1,042 | <p>For instance, my query is like the following using SQL Server 2005:</p>
<pre><code>SELECT * FROM Table WHERE FREETEXT(SearchField, 'c#')
</code></pre>
<p>I have a full text index defined to use the column SearchField which returns results when using:</p>
<pre><code>SELECT * FROM Table WHERE SearchField LIKE '%c#%'
</code></pre>
<p>I believe # is a special letter, so how do I allow FREETEXT to work correctly for the query above?</p>

1,069 | <p>I'm working on a <strong>multithreaded</strong> C++ application that is corrupting the heap. The usual tools to locate this corruption seem to be inapplicable. Old builds (18 months old) of the source code exhibit the same behaviour as the most recent release, so this has been around for a long time and just wasn't noticed; on the downside, source deltas can't be used to identify when the bug was introduced - there are <em>a lot</em> of code changes in the repository.</p>
<p>The prompt for crashing behaviuor is to generate throughput in this system - socket transfer of data which is munged into an internal representation. I have a set of test data that will periodically cause the app to exception (various places, various causes - including heap alloc failing, thus: heap corruption).</p>
<p>The behaviour seems related to CPU power or memory bandwidth; the more of each the machine has, the easier it is to crash. Disabling a hyper-threading core or a dual-core core reduces the rate of (but does not eliminate) corruption. This suggests a timing related issue.</p>
<p>Now here's the rub:<br>
When it's run under a lightweight debug environment (say <code>Visual Studio 98 / AKA MSVC6</code>) the heap corruption is reasonably easy to reproduce - ten or fifteen minutes pass before something fails horrendously and exceptions, like an <code>alloc;</code> when running under a sophisticated debug environment (Rational Purify, <code>VS2008/MSVC9</code> or even Microsoft Application Verifier) the system becomes memory-speed bound and doesn't crash (Memory-bound: CPU is not getting above <code>50%</code>, disk light is not on, the program's going as fast it can, box consuming <code>1.3G</code> of 2G of RAM). So, <strong>I've got a choice between being able to reproduce the problem (but not identify the cause) or being able to idenify the cause or a problem I can't reproduce.</strong></p>
<p>My current best guesses as to where to next is:</p>
<ol>
<li>Get an insanely grunty box (to replace the current dev box: 2Gb RAM in an <code>E6550 Core2 Duo</code>); this will make it possible to repro the crash causing mis-behaviour when running under a powerful debug environment; or</li>
<li>Rewrite operators <code>new</code> and <code>delete</code> to use <code>VirtualAlloc</code> and <code>VirtualProtect</code> to mark memory as read-only as soon as it's done with. Run under <code>MSVC6</code> and have the OS catch the bad-guy who's writing to freed memory. Yes, this is a sign of desperation: who the hell rewrites <code>new</code> and <code>delete</code>?! I wonder if this is going to make it as slow as under Purify et al.</li>
</ol>
<p>And, no: Shipping with Purify instrumentation built in is not an option.</p>
<p>A colleague just walked past and asked "Stack Overflow? Are we getting stack overflows now?!?"</p>
<p>And now, the question: <strong>How do I locate the heap corruptor?</strong></p>
<hr>
<p>Update: balancing <code>new[]</code> and <code>delete[]</code> seems to have gotten a long way towards solving the problem. Instead of 15mins, the app now goes about two hours before crashing. Not there yet. Any further suggestions? The heap corruption persists.</p>
<p>Update: a release build under Visual Studio 2008 seems dramatically better; current suspicion rests on the <code>STL</code> implementation that ships with <code>VS98</code>.</p>
<hr>
<blockquote>
<ol start="3">
<li>Reproduce the problem. <code>Dr Watson</code> will produce a dump that might be helpful in further analysis. </li>
</ol>
</blockquote>
<p>I'll take a note of that, but I'm concerned that Dr Watson will only be tripped up after the fact, not when the heap is getting stomped on.</p>
<blockquote>
<p>Another try might be using <code>WinDebug</code> as a debugging tool which is quite powerful being at the same time also lightweight.</p>
</blockquote>
<p>Got that going at the moment, again: not much help until something goes wrong. I want to catch the vandal in the act.</p>
<blockquote>
<p>Maybe these tools will allow you at least to narrow the problem to certain component.</p>
</blockquote>
<p>I don't hold much hope, but desperate times call for...</p>
<blockquote>
<p>And are you sure that all the components of the project have correct runtime library settings (<code>C/C++ tab</code>, Code Generation category in VS 6.0 project settings)?</p>
</blockquote>
<p>No I'm not, and I'll spend a couple of hours tomorrow going through the workspace (58 projects in it) and checking they're all compiling and linking with the appropriate flags.
<hR>
Update: This took 30 seconds. Select all projects in the <code>Settings</code> dialog, unselect until you find the project(s) that don't have the right settings (they all had the right settings).</p>

1,145 | <p>I've tried to write a string replace function in C, which works on a <code>char *</code>, which has been allocated using <code>malloc()</code>. It's a little different in that it will find and replace strings, rather than characters in the starting string.</p>
<p>It's trivial to do if the search and replace strings are the same length (or the replace string is shorter than the search string), since I have enough space allocated. If I try to use <code>realloc()</code>, I get an error that tells me I am doing a double free - which I don't see how I am, since I am only using <code>realloc()</code>.</p>
<p>Perhaps a little code will help:</p>
<pre><code>void strrep(char *input, char *search, char *replace) {
int searchLen = strlen(search);
int replaceLen = strlen(replace);
int delta = replaceLen - searchLen;
char *find = input;
while (find = strstr(find, search)) {
if (delta > 0) {
realloc(input, strlen(input) + delta);
find = strstr(input, search);
}
memmove(find + replaceLen, find + searchLen, strlen(input) - (find - input));
memmove(find, replace, replaceLen);
}
}
</code></pre>
<p>The program works, until I try to <code>realloc()</code> in an instance where the replaced string will be longer than the initial string. (It still kind of works, it just spits out errors as well as the result).</p>
<p>If it helps, the calling code looks like:</p>
<pre><code>#include <stdio.h>
#include <string.h>
#include <stdlib.h>
void strrep(char *input, char *search, char *replace);
int main(void) {
char *input = malloc(81);
while ((fgets(input, 81, stdin)) != NULL) {
strrep(input, "Noel", "Christmas");
}
}
</code></pre>

1,171 | <p>I need to be able to manipulate a large (10^7 nodes) graph in python. The data corresponding to each node/edge is minimal, say, a small number of strings. What is the most efficient, in terms of <strong><em>memory and speed</em></strong>, way of doing this? </p>
<p>A dict of dicts is more flexible and simpler to implement, but I intuitively expect a list of lists to be faster. The list option would also require that I keep the data separate from the structure, while dicts would allow for something of the sort:</p>
<pre><code>graph[I][J]["Property"]="value"
</code></pre>
<p>What would you suggest?</p>
<hr>
<p>Yes, I should have been a bit clearer on what I mean by efficiency. In this particular case I mean it in terms of random access retrieval.</p>
<p>Loading the data in to memory isn't a huge problem. That's done once and for all. The time consuming part is visiting the nodes so I can extract the information and measure the metrics I'm interested in.</p>
<p>I hadn't considered making each node a class (properties are the same for all nodes) but it seems like that would add an extra layer of overhead? I was hoping someone would have some direct experience with a similar case that they could share. After all, graphs are one of the most common abstractions in CS.</p>

<p>If you are given N maximally distant colors (and some associated distance metric), can you come up with a way to sort those colors into some order such that the first M are also reasonably close to being a maximally distinct set?</p>
<p>In other words, given a bunch of distinct colors, come up with an ordering so I can use as many colors as I need starting at the beginning and be reasonably assured that they are all distinct and that nearby colors are also very distinct (e.g., bluish red isn't next to reddish blue).</p>
<p>Randomizing is OK but certainly not optimal.</p>
<p><em>Clarification: Given some large and visually distinct set of colors (say 256, or 1024), I want to sort them such that when I use the first, say, 16 of them that I get a relatively visually distinct subset of colors. This is equivalent, roughly, to saying I want to sort this list of 1024 so that the closer individual colors are visually, the farther apart they are on the list.</em></p>

1,390 | <p>I'm setting up a dedicated SQL Server 2005 box on Windows Server 2008 this week, and would like to pare it down to be as barebones as possible while still being fully functional.</p>
<p>To that end, the "Server Core" option sounds appealing, but I'm not clear about whether or not I can run SQL Server on that SKU. Several services are addressed on the <a href="http://www.microsoft.com/windowsserver2008/en/us/compare-core-installation.aspx" rel="noreferrer">Microsoft website</a>, but I don't see any indication about SQL Server.</p>
<p>Does anyone know definitively?</p>

1,401 | <p>I have a custom validation function in JavaScript in a user control on a .Net 2.0 web site which checks to see that the fee paid is not in excess of the fee amount due. </p>
<p>I've placed the validator code in the <code>ascx</code> file, and I have also tried using <code>Page.ClientScript.RegisterClientScriptBlock()</code> and in both cases the validation fires, but cannot find the JavaScript function.</p>
<p>The output in Firefox's error console is <code>"feeAmountCheck is not defined"</code>. Here is the function (this was taken directly from firefox->view source)</p>
<pre><code><script type="text/javascript">
function feeAmountCheck(source, arguments)
{
var amountDue = document.getElementById('ctl00_footerContentHolder_Fees1_FeeDue');
var amountPaid = document.getElementById('ctl00_footerContentHolder_Fees1_FeePaid');
if (amountDue.value > 0 && amountDue >= amountPaid)
{
arguments.IsValid = true;
}
else
{
arguments.IsValid = false;
}
return arguments;
}
</script>
</code></pre>
<p>Any ideas as to why the function isn't being found? How can I remedy this without having to add the function to my master page or consuming page?</p>

1,408 | <p>Is it possible to configure <a href="http://www.apachefriends.org/en/xampp.html" rel="noreferrer">xampp</a> to serve up a file outside of the <code>htdocs</code> directory?</p>

1,451 | <p>I often encounter the following scenario where I need to offer many different types of permissions. I primarily use ASP.NET / VB.NET with SQL Server 2000.</p>
<p><strong>Scenario</strong></p>
<p>I want to offer a dynamic permission system that can work on different parameters. Let's say that I want to give either a department or just a specific person access to an application. And pretend that we have a number of applications that keeps growing.</p>
<p>In the past, I have chosen one of the following two ways that I know to do this.</p>
<ol>
<li><p>Use a single permission table with special columns that are used for
determining a how to apply the parameters. The special columns in
this example are <code>TypeID</code> and <code>TypeAuxID</code>. The SQL would look something
like this.</p>
<pre><code>SELECT COUNT(PermissionID)
FROM application_permissions
WHERE
(TypeID = 1 AND TypeAuxID = @UserID) OR
(TypeID = 2 AND TypeAuxID = @DepartmentID)
AND ApplicationID = 1
</code></pre>
</li>
<li><p>Use a mapping table for each type of permission, then joining them
all together.</p>
<pre><code>SELECT COUNT(perm.PermissionID)
FROM application_permissions perm
LEFT JOIN application_UserPermissions emp
ON perm.ApplicationID = emp.ApplicationID
LEFT JOIN application_DepartmentPermissions dept
ON perm.ApplicationID = dept.ApplicationID
WHERE q.SectionID=@SectionID
AND (emp.UserID=@UserID OR dept.DeptID=@DeptID OR
(emp.UserID IS NULL AND dept.DeptID IS NULL)) AND ApplicationID = 1
ORDER BY q.QID ASC
</code></pre>
</li>
</ol>
<p><strong>My Thoughts</strong></p>
<p>I hope that the examples make sense. I cobbled them together.</p>
<p>The first example requires less work, but neither of them feel like the best answer. Is there a better way to handle this?</p>

1,476 | <p>How do you express an integer as a binary number with Python literals?</p>
<p>I was easily able to find the answer for hex:</p>
<pre><code>>>> 0x12AF
4783
>>> 0x100
256
</code></pre>
<p>and octal:</p>
<pre><code>>>> 01267
695
>>> 0100
64
</code></pre>
<p><strong>How do you use literals to express binary in Python?</strong></p>
<hr>
<p><strong><em>Summary of Answers</em></strong></p>
<ul>
<li>Python 2.5 and earlier: can express binary using <code>int('01010101111',2)</code> but not with a literal.</li>
<li>Python 2.5 and earlier: there is <em>no way</em> to express binary literals.</li>
<li>Python 2.6 beta: You can do like so: <code>0b1100111</code> or <code>0B1100111</code>.</li>
<li>Python 2.6 beta: will also allow <code>0o27</code> or <code>0O27</code> (second character is the letter O) to represent an octal.</li>
<li>Python 3.0 beta: Same as 2.6, but will no longer allow the older <code>027</code> syntax for octals.</li>

1,528 | <p>I'm looking for some way to effectively hide inherited members. I have a library of classes which inherit from common base classes. Some of the more recent descendant classes inherit dependency properties which have become vestigial and can be a little confusing when using <em>IntelliSense</em> or using the classes in a visual designer.</p>
<p>These classes are all controls that are written to be compiled for either WPF or Silverlight 2.0. I know about <code>ICustomTypeDescriptor</code> and <code>ICustomPropertyProvider</code>, but I'm pretty certain those can't be used in Silverlight. </p>
<p>It's not as much a functional issue as a usability issue. What should I do?</p>
<p><strong>Update</strong></p>
<p>Some of the properties that I would really like to hide come from ancestors that are not my own and because of a specific tool I'm designing for, I can't do member hiding with the <code>new</code> operator. (I know, it's ridiculous)</p>

1,535 | <p>I've never been completely happy with the way exception handling works, there's a lot exceptions and try/catch brings to the table (stack unwinding, etc.), but it seems to break a lot of the OO model in the process.</p>
<p>Anyway, here's the problem:</p>
<p>Let's say you have some class which wraps or includes networked file IO operations (e.g. reading and writing to some file at some particular UNC path somewhere). For various reasons you don't want those IO operations to fail, so if you detect that they fail you retry them and you keep retrying them until they succeed or you reach a timeout. I already have a convenient RetryTimer class which I can instantiate and use to sleep the current thread between retries and determine when the timeout period has elapsed, etc.</p>
<p>The problem is that you have a bunch of IO operations in several methods of this class, and you need to wrap each of them in try-catch / retry logic.</p>
<p>Here's an example code snippet:</p>
<pre><code>RetryTimer fileIORetryTimer = new RetryTimer(TimeSpan.FromHours(10));
bool success = false;
while (!success)
{
try
{
// do some file IO which may succeed or fail
success = true;
}
catch (IOException e)
{
if (fileIORetryTimer.HasExceededRetryTimeout)
{
throw e;
}
fileIORetryTimer.SleepUntilNextRetry();
}
}
</code></pre>
<p>So, how do you avoid duplicating most of this code for every file IO operation throughout the class? My solution was to use anonymous delegate blocks and a single method in the class which executed the delegate block passed to it. This allowed me to do things like this in other methods:</p>
<pre><code>this.RetryFileIO( delegate()
{
// some code block
} );
</code></pre>
<p>I like this somewhat, but it leaves a lot to be desired. I'd like to hear how other people would solve this sort of problem.</p>

1,607 | <p>What are the best methods for tracking and/or automating DB schema changes? Our team uses Subversion for version control and we've been able to automate some of our tasks this way (pushing builds up to a staging server, deploying tested code to a production server) but we're still doing database updates manually. I would like to find or create a solution that allows us to work efficiently across servers with different environments while continuing to use Subversion as a backend through which code and DB updates are pushed around to various servers.</p>
<p>Many popular software packages include auto-update scripts which detect DB version and apply the necessary changes. Is this the best way to do this even on a larger scale (across multiple projects and sometimes multiple environments and languages)? If so, is there any existing code out there that simplifies the process or is it best just to roll our own solution? Has anyone implemented something similar before and integrated it into Subversion post-commit hooks, or is this a bad idea?</p>
<p>While a solution that supports multiple platforms would be preferable, we definitely need to support the Linux/Apache/MySQL/PHP stack as the majority of our work is on that platform.</p>

1,709 | <p>My dilemma is, basically, how to share an enumeration between two applications.</p>
<p>The users upload documents through a front-end application that is on the web. This application calls a web service of the back-end application and passes the document to it. The back-end app saves the document and inserts a row in the <em>Document</em> table.</p>
<p>The document type (7 possible document types: <em>Invoice</em>, <em>Contract</em> etc.) is passed as a parameter to the web service's <em>UploadDocument</em> method. The question is, what should the type (and possible values) of this parameter be?</p>
<p>Since you need to hardcode these values in both applications, I think it is O.K. to use a descriptive string (<em>Invoice</em>, <em>Contract</em>, <em>WorkOrder</em>, <em>SignedWorkOrder</em>). </p>
<p>Is it maybe a better approach to create a <em>DocumentTypes</em> enumeration in the first application, and to reproduce it also in the second application, and then pass the corresponding integer value to the web service between them?</p>

As in one server at location A and another at location B that sync up their local versions of the repository automatically. That way when someone at either location interacts with the repository they are accessing their respective local server and therefore has faster response times.</p>

1,829 | <p>I've got a menu in Python. That part was easy. I'm using <code>raw_input()</code> to get the selection from the user. </p>
<p>The problem is that <code>raw_input</code> (and input) require the user to press <kbd>Enter</kbd> after they make a selection. Is there any way to make the program act immediately upon a keystroke? Here's what I've got so far:</p>
<pre><code>import sys
print """Menu
1) Say Foo
2) Say Bar"""
answer = raw_input("Make a selection> ")
if "1" in answer: print "foo"
elif "2" in answer: print "bar"
</code></pre>
<p>It would be great to have something like</p>
<pre><code>print menu
while lastKey = "":
lastKey = check_for_recent_keystrokes()
if "1" in lastKey: #do stuff...
</code></pre>

1,836 | <p>OK. This is a bit of a vanity app, but I had a situation today at work where I was in a training class and the machine was set to lock every 10 minutes. Well, if the trainers got excited about talking - as opposed to changing slides - the machine would lock up.</p>
<p>I'd like to write a teeny app that has nothing but a taskbar icon that does nothing but move the mouse by 1 pixel every 4 minutes. </p>
<p>I can do that in 3 ways with Delphi (my strong language) but I'm moving to C# for work and I'd like to know the path of least resistance there.</p>

1,873 | <p>How do I delimit a Javascript data-bound string parameter in an anchor <code>OnClick</code> event?</p>
<ul>
<li>I have an anchor tag in an ASP.NET Repeater control.</li>
<li>The <code>OnClick</code> event of the anchor contains a call to a Javascript function.</li>
<li>The Javascript function takes a string for its input parameter.</li>
<li>The string parameter is populated with a data-bound value from the Repeater.</li>
</ul>
<p>I need the "double quotes" for the <code>Container.DataItem</code>.<br />
I need the 'single quotes' for the <code>OnClick</code>.</p>
<p>And I still need <em>one more delimiter</em> (triple quotes?) for the input string parameter of the Javascript function call.</p>
<p>Since I can't use 'single quotes' again, how do I ensure the Javascript function knows the input parameter is a string and not an integer?</p>
<p>Without the extra quotes around the input string parameter, the Javascript function thinks I'm passing in an integer.</p>
<p>The anchor:</p>
<pre><code><a id="aShowHide" onclick='ToggleDisplay(<%# DataBinder.Eval(Container.DataItem, "JobCode") %>);' >Show/Hide</a>
</code></pre>
<p>And there is my Javascript:</p>
<pre><code><script language="JavaScript" type="text/javascript">
/* Shows/Hides the Jobs Div */
function ToggleDisplay(jobCode)
{
/* Each div has its ID set dynamically ('d' plus the JobCode) */
var elem = document.getElementById('d' + jobCode);
if (elem)
{
if (elem.style.display != 'block')
{
elem.style.display = 'block';
elem.style.visibility = 'visible';
}
else
{
elem.style.display = 'none';
elem.style.visibility = 'hidden';
}
}
}
</script>

1,908 | <p>I have a bunch of latitude/longitude pairs that map to known x/y coordinates on a (geographically distorted) map.</p>
<p>Then I have one more latitude/longitude pair. I want to plot it on the map as best is possible. How do I go about doing this?</p>
<p>At first I decided to create a system of linear equations for the three nearest lat/long points and compute a transformation from these, but this doesn't work well at all. Since that's a linear system, I can't use more nearby points either.</p>
<p>You can't assume North is up: all you have is the existing lat/long->x/y mappings.</p>
<p>EDIT: it's not a Mercator projection, or anything like that. It's arbitrarily distorted for readability (think subway map). I want to use only the nearest 5 to 10 mappings so that distortion on other parts of the map doesn't affect the mapping I'm trying to compute.</p>
<p>Further, the entire map is in a very small geographical area so there's no need to worry about the globe--flat-earth assumptions are good enough.</p>

1,936 | <p>Using ASP.NET MVC there are situations (such as form submission) that may require a <code>RedirectToAction</code>. </p>
<p>One such situation is when you encounter validation errors after a form submission and need to redirect back to the form, but would like the URL to reflect the URL of the form, not the action page it submits to.</p>
<p>As I require the form to contain the originally <code>POST</code>ed data, for user convenience, as well as validation purposes, how can I pass the data through the <code>RedirectToAction()</code>? If I use the viewData parameter, my <code>POST</code> parameters will be changed to <code>GET</code> parameters.</p>

1,949 | <p>In order to fully use LinqToSql in an ASP.net 3.5 application, it is necessary to create <a href="http://msdn.microsoft.com/en-us/library/system.data.linq.datacontext.aspx" rel="noreferrer">DataContext</a> <a href="http://dotnetslackers.com/articles/csharp/InsideTheLINQToSQLDataContextClass.aspx" rel="noreferrer">classes</a> (which is usually done using the designer in VS 2008). From the UI perspective, the DataContext is a design of the sections of your database that you would like to expose to through LinqToSql and is integral in setting up the ORM features of LinqToSql.</p>
<p>My question is: I am setting up a project that uses a large database where all tables are interconnected in some way through Foreign Keys. My first inclination is to make one huge DataContext class that models the entire database. That way I could in theory (though I don't know if this would be needed in practice) use the Foreign Key connections that are generated through LinqToSql to easily go between related objects in my code, insert related objects, etc.</p>
<p>However, after giving it some thought, I am now thinking that it may make more sense to create multiple DataContext classes, each one relating to a specific namespace or logical interrelated section within my database. My main concern is that instantiating and disposing one huge DataContext class all the time for individual operations that relate to specific areas of the Database would be impose an unnecessary imposition on application resources. Additionally, it is easier to create and manage smaller DataContext files than one big one. The thing that I would lose is that there would be some distant sections of the database that would not be navigable through LinqToSql (even though a chain of relationships connects them in the actual database). Additionally, there would be some table classes that would exist in more than one DataContext.</p>
<p>Any thoughts or experience on whether multiple DataContexts (corresponding to DB namespaces) are appropriate in place of (or in addition to) one very large DataContext class (corresponding to the whole DB)?</p>

1,988 | <p>I have read a lot that LISP can redefine syntax on the fly, presumably with macros. I am curious how far does this actually go? Can you redefine the language structure so much that it borderline becomes a compiler for another language? For example, could you change the functional nature of LISP into a more object oriented syntax and semantics, maybe say having syntax closer to something like Ruby?</p>
<p>Especially, is it possible to get rid of the parenthesis hell using macros? I have learned enough (Emacs-)LISP to customize Emacs with my own micro-features, but I am very curious how far macros can go in customizing the language.</p>

1,995 | <p>I have values stored as strings in a <code>DataTable</code> where each value could really represent an <code>int</code>, <code>double</code>, or <code>string</code> (they were all converted to strings during an import process from an external data source).

2,027 | <p>When learning a new programming language, one of the possible roadblocks you might encounter is the question whether the language is, by default, <em>pass-by-value or pass-by-reference</em>.</p>

2,046 | <p>As a novice in practicing test-driven development, I often end up in a quandary as to how to unit test persistence to a database.</p>
<p>I know that technically this would be an integration test (not a unit test), but I want to find out the best strategies for the following:</p>
<ol>
<li>Testing queries. </li>
<li>Testing inserts. How do I know that the insert that has gone wrong if it fails? I can test it by inserting and then querying, but how can I know that the query wasn't wrong? </li>
<li>Testing updates and deletes -- same as testing inserts</li>
</ol>
<p>What are the best practices for doing these?</p>
<hr>
<p>Regarding testing SQL: I am aware that this could be done, but if I use an O/R Mapper like NHibernate, it attaches some naming warts in the aliases used for the output queries, and as that is somewhat unpredictable I'm not sure I could test for that.</p>
<p>Should I just, abandon everything and simply trust NHibernate? I'm not sure that's prudent.</p>

2,120 | <p>I want to get the MD5 Hash of a string value in SQL Server 2005. I do this with the following command:</p>

2,256 | <p>Is there a way of mapping data collected on a stream or array to a data structure or vice-versa?
In C++ this would simply be a matter of casting a pointer to the stream as a data type I want to use (or vice-versa for the reverse)
eg: in C++</p>
<pre><code>Mystruct * pMyStrct = (Mystruct*)&SomeDataStream;
pMyStrct->Item1 = 25;
int iReadData = pMyStrct->Item2;
</code></pre>
<p>obviously the C++ way is pretty unsafe unless you are sure of the quality of the stream data when reading incoming data, but for outgoing data is super quick and easy.</p>

2,311 | <p>I have created a PHP-script to update a web server that is live inside a local directory.
I'm migrating the script into Python. It works fine for the most part, but after a PUT command, the size of the file appears to change. Thus, the size of the file is different from that of the file on the server. </p>
<p>Once I download again the file from the FTP server, the only difference is the CR/LF mark. This annoys me because the same script is comparing the size of the files to update. Also, in case it means anything, the script works perfectly in PHP vía ftp_put.</p>
<pre><code>from ftplib import FTP
ftpserver = "myserver"
ftpuser = "myuser"
ftppass = "mypwd"
locfile = "g:/test/style.css"
ftpfile = "/temp/style.css"

ftp = FTP(ftpserver, ftpuser, ftppass)
except:

f = open (locfile, "r")

2,328 | <p>I have a problem with maintaining state in an ASP.NET AJAX page. Short version: I need some way to update the page ViewState after an async callback has been made, to reflect any state changes the server made during the async call. </p>
<p>This seems to be a common problem, but I will describe my scenario to help explain:</p>
<p>I have a grid-like control which has some JavaScript enhancements - namely, the ability to drag and drop columns and rows. When a column or row is dropped into a new position, an AJAX method is invoked to notify the control server-side and fire a corresponding server-side event ("OnColumnMoved" or "OnRowMoved").</p>
<p>ASP.NET AJAX calls, by default, send the entire page as the request. That way the page goes through a complete lifecycle, viewstate is persisted and the state of the control is restored before the RaiseCallbackEvent method is invoked.</p>
<p>However, since the AJAX call does not update the page, the ViewState reflects the <em>original</em> state of the control, even after the column or row has been moved. So the second time a client-side action occurs, the AJAX request goes to the server and the page & control are built back up again to reflect the <em>first</em> state of the control, not the state after the first column or row was moved.</p>
<p>This problem extends to many implications. For example if we have a client-side/AJAX action to add a new item to the grid, and then a row is dragged, the grid is built server-side with one less item than on the client-side.</p>
<p>And finally & most seriously for my specific example, the actual data source object we are acting upon is stored in the page ViewState. That was a design decision to allow keeping a stateful copy of the manipulated data which can either be committed to DB after many manipulations or discarded if the user backs out. That is very difficult to change.</p>
<p>So, again, I need a way for the page ViewState to be updated on callback after the AJAX method is fired.</p>

2,349 | <p>In Windows, in any windows form or web browser, you can use the tab button to switch focus through all of the form fields. </p>
<p>It will stop on textboxes, radiobuttons, checkboxes, dropdown menus, etc. </p>
<p>However, in Mac OSX, tab skips dropdown menus. Is there anyway to change this behavior, or access the above items mentioned, without using a mouse?</p>

2,384 | <p>I'm trying to read binary data using C#. I have all the information about the layout of the data in the files I want to read. I'm able to read the data "chunk by chunk", i.e. getting the first 40 bytes of data converting it to a string, get the next 40 bytes.</p>
<p>Since there are at least three slightly different version of the data, I would like to read the data directly into a struct. It just feels so much more right than by reading it "line by line".</p>
<p><strong>I have tried the following approach but to no avail:</strong></p>
<pre><code>StructType aStruct;
int count = Marshal.SizeOf(typeof(StructType));
byte[] readBuffer = new byte[count];
BinaryReader reader = new BinaryReader(stream);
readBuffer = reader.ReadBytes(count);
GCHandle handle = GCHandle.Alloc(readBuffer, GCHandleType.Pinned);
aStruct = (StructType) Marshal.PtrToStructure(handle.AddrOfPinnedObject(), typeof(StructType));
handle.Free();
</code></pre>
<p>The stream is an opened FileStream from which I have began to read from. I get an <code>AccessViolationExceptio</code>n when using <code>Marshal.PtrToStructure</code>.</p>
<p>The stream contains more information than I'm trying to read since I'm not interested in data at the end of the file.</p>
<p><strong>The struct is defined like:</strong></p>
<pre><code>[StructLayout(LayoutKind.Explicit)]
struct StructType
{
[FieldOffset(0)]
public string FileDate;
[FieldOffset(8)]
public string FileTime;
[FieldOffset(16)]
public int Id1;
[FieldOffset(20)]
public string Id2;
}
</code></pre>
<p>The examples code is changed from original to make this question shorter.</p>
<p>How would I read binary data from a file into a struct?</p>

2,481 | <p>I've been able to find details on several self-balancing <code>BST</code>s through several sources, but I haven't found any good descriptions detailing which one is best to use in different situations (or if it really doesn't matter). </p>
<p>I want a <code>BST</code> that is optimal for storing in excess of ten million nodes. The order of insertion of the nodes is basically random, and I will never need to delete nodes, so insertion time is the only thing that would need to be optimized. </p>
<p>I intend to use it to store previously visited game states in a puzzle game, so that I can quickly check if a previous configuration has already been encountered.</p>

2,525 | <p>My product has several components: ASP.NET, Windows Forms App and Windows Service. 95% or so of the code is written in VB.NET.</p>
<p>For Intellectual Property reasons, I need to obfuscate the code, and until now I have been using a version of dotfuscator which is now over 5 years old. I'm thinking it is time to move to a new generation tool. What I'm looking for is a list of requirements which I should consider when searching for a new obfuscator.</p>
<p>What I know I should look for so far:</p>
<ul>
<li><strong><em>Serialization/De-serialization</em></strong>. In my current solution, I simply tell the tool <strong>not</strong> to obfuscate any class data members because the pain of not being able to load data which was previously serialized is simply too big.</li>
<li><strong><em>Integration with Build Process</em></strong></li>
<li><strong><em>Working with ASP.NET</em></strong>. In the past, I have found this problematic due to changing .dll names (you often have one per page) - which not all tools handle well.</li>

2,770 | <p>When working on ASP.NET 1.1 projects I always used the Global.asax to catch all errors. I'm looking for a similar way to catch all exceptions in a Windows Forms user control, which ends up being a hosted IE control. What is the proper way to go about doing something like this?</p>
