<p>Using C# 2.0 what is the best way to implement dynamic form controls?</p>
<p>I need to provide a set of controls per data object, so should i just do it manually and lay them out while increment the top value or is there a better way?</p>

<p>Let's say you want to save a bunch of files somewhere, for instance in BLOBs. Let's say you want to dish these files out via a web page and have the client automatically open the correct application/viewer.</p>
<p>Assumption: The browser figures out which application/viewer to use by the mime-type (content-type?) header in the HTTP response.</p>
<p>Based on that assumption, in addition to the bytes of the file, you also want to save the MIME type.</p>
<p>How would you find the MIME type of a file? I'm currently on a Mac, but this should also work on Windows. </p>
<p>Does the browser add this information when posting the file to the web page?</p>
<p>Is there a neat python library for finding this information? A WebService or (even better) a downloadable database?</p>

<p>A very niche problem:</p>
<p>I sometimes (30% of the time) get an 'undefined handler' javascript error on line 3877 of the prototype.js library (version 1.6.0.2 from google: <a href="http://ajax.googleapis.com/ajax/libs/prototype/1.6.0.2/prototype.js" rel="nofollow noreferrer">http://ajax.googleapis.com/ajax/libs/prototype/1.6.0.2/prototype.js</a>).</p>
<p>Now on this page I have a Google Map and I use the Prototype Window library.</p>
<p>The problem occurs in IE7 and FF3.</p>
<p>This is the info FireBug gives:</p>
<pre><code>handler is undefined
? in prototype.js@3871()prototype.js (line 3877)
handler.call(element, event);
</code></pre>
<p>I switched to a local version of prototypejs and added some debugging in the offending method (createWraper) but the debugging never appears before the error...</p>
<p>I googled around and found 1 other mention of the error on the same line, but no answer so I'm posting it here where maybe, some day someone will have an answer :).</p>

<p>I've seen lots of examples of making an entire regular expression case-insensitive. What I'm wondering about is having just part of the expression be case-insensitive.</p>
<p>For example, let's say I have a string like this:</p>
<pre><code>fooFOOfOoFoOBARBARbarbarbAr
</code></pre>
<p>What if I want to match all occurrences of "foo" regardless of case but I only want to match the upper-case "BAR"s?</p>
<p>The ideal solution would be something that works across regex flavors but I'm interested in hearing language-specific ones as well (Thanks <a href="https://stackoverflow.com/questions/43632/can-you-make-just-part-of-a-regex-case-insensitive#43636">Espo</a>)</p>
<p><strong><em>Edit</em></strong></p>
<p>The link Espo provided was very helpful. There's a good example in there about turning modifiers on and off within the expression.</p>
<p>For my contrived example, I can do something like this:</p>
<pre><code>(?i)foo*(?-i)|BAR
</code></pre>
<p>which makes the match case-insensitive for just the foo portion of the match.</p>
<p>That seemed to work in most regex implementations except Javascript, Python, and a few others (as Espo mentioned). </p>
<p>The big ones that I was wondering about (Perl, PHP, .NET) all support inline mode changes.</p>

<p>Given the code bellow, how do I style the radio buttons to be next to the labels and style the label of the selected radio button differently than the other labels?</p>
<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-html lang-html prettyprint-override"><code><link href="http://yui.yahooapis.com/2.5.2/build/reset-fonts-grids/reset-fonts-grids.css" rel="stylesheet">
<link href="http://yui.yahooapis.com/2.5.2/build/base/base-min.css" rel="stylesheet">
<div class="input radio">
<fieldset>
<legend>What color is the sky?</legend>
<input type="hidden" name="color" value="" id="SubmitQuestion" />
<input type="radio" name="color" id="SubmitQuestion1" value="1" />
<label for="SubmitQuestion1">A strange radient green.</label>
<input type="radio" name="color" id="SubmitQuestion2" value="2" />
<label for="SubmitQuestion2">A dark gloomy orange</label>
<input type="radio" name="color" id="SubmitQuestion3" value="3" />
<label for="SubmitQuestion3">A perfect glittering blue</label>
</fieldset>
</div></code></pre>
</div>
</div>
</p>
<p>Also let me state that I use the yui css styles as base. If you are not familir with them, they can be found here:</p>
<ul>
<li><a href="http://yui.yahooapis.com/2.5.2/build/reset-fonts-grids/reset-fonts-grids.css" rel="nofollow noreferrer">reset-fonts-grids.css</a></li>
<li><a href="http://yui.yahooapis.com/2.5.2/build/base/base-min.css" rel="nofollow noreferrer">base-min.css</a></li>
</ul>
<p>Documentation for them both here : <a href="http://developer.yahoo.com/yui/reset/" rel="nofollow noreferrer">Yahoo! UI Library</a></p>
<p>@pkaeding: Thanks. I tried some floating both thing that just looked messed up. The styling active radio button seemed to be doable with some input[type=radio]:active nomination on a google search, but I didnt get it to work properly. So the question I guess is more: Is this possible on all of todays modern browsers, and if not, what is the minimal JS needed?</p>

<p>I've got some (C#) code that relies on today's date to correctly calculate things in the future. If I use today's date in the testing, I have to repeat the calculation in the test, which doesn't feel right. What's the best way to set the date to a known value within the test so that I can test that the result is a known value?</p>

<p>I have a line color property in my custom grid control. I want it to default to <code>Drawing.SystemColors.InactiveBorder</code>. I tried:</p>
<pre><code>[DefaultValue(typeof(System.Drawing.SystemColors), "InactiveBorder")]
public Color LineColor { get; set; }
</code></pre>
<p>But it doesn't seem to work. How do I do that with the default value attribute?</p>

<p>For my day job, I live in Emacs. Utterly. I also have become pretty dependent on CScope to help me find things in the code.</p>
<p>Normally, I have 2 windows in a split (C-x 3):
<a href="http://bitthicket.com/files/emacs-2split.JPG">alt text http://bitthicket.com/files/emacs-2split.JPG</a></p>
<p>And I use the right window for code buffers and the left window for the CScope search buffer. When you do a CScope search and select a result, it automatically updates the right-side window to show the buffer referred to by the result. This is all well and good, except that it causes me to lose my place in some other buffer that I was studying. Sometimes this is no biggie, because [C-s u] gets me back to where I was.</p>
<p>What would be better, though, is to have 3 split windows like this ([C-x 2] in the left window):
<a href="http://bitthicket.com/files/emacs-3split.jpg">alt text http://bitthicket.com/files/emacs-3split.jpg</a></p>
<p>And have the bottom left window contain the CScope search buffer, and the top left window be the only buffer that CScope ever updates. That way, I can see my CScope searches and navigate around the code without losing the buffer I'm focused on.</p>
<p>Anyone know how I can do that?</p>

<p>Can you please tell me how much is <code>(-2) % 5</code>?
According to my Python interpreter is 3, but do you have a wise explanation for this?</p>
<p>I've read that in some languages the result can be machine-dependent, but I'm not sure though.</p>

<p>I have a <code>String</code> representation of a date that I need to create a <code>Date</code> or <code>Calendar</code> object from. I've looked through <code>Date</code> and <code>Calendar</code> APIs but haven't found anything that can do this other than creating my own ugly parse method. I know there must be a way, does anyone know of a solution?</p>

<p>I have a distributed Java application running on 5 application servers. The servers all use the same Oracle 9i database running on a 6th machine.</p>
<p>The application need to prefetch a batch of 100 IDs from a sequence. It's relatively easy to do in a single-threaded, non-distributed environment, you can just issue these queries:</p>
<pre class="lang-sql prettyprint-override"><code>SELECT seq.nextval FROM dual;
ALTER SEQUENCE seq INCREMENT BY 100;
SELECT seq.nextval FROM dual;
</code></pre>
<p>The first select fetches the first sequence ID that the application can use, the second select returns the last one that can be used.</p>
<p>Things get way more interesting in a multithreaded environment. You can't be sure that before the second select another thread doesn't increase the sequence by 100 again. This issue can be solved by synchronizing the access on the Java side - you only let one thread begin fetching the IDs at one time.</p>
<p>The situation becomes really hard when you can't synchronize because parts of the application doesn't run on the same JVM, not even on the same physical machine. I found some references on forums that others have problems with solving this problem too, but none of the answers are really working not to mention being reasonable.</p>
<p>Can the community provide a solution for this problem?</p>
<p>Some more information:</p>
<ul>
<li>I can't really play with the transaction isolation levels. I use JPA and the change would affect the entire application, not only the prefetching queries and that's not acceptable for me.</li>
<li><p>On PostgreSQL I could do the following:
<code>SELECT setval('seq', NEXTVAL('seq') + n - 1)</code></p></li>
<li><p>The solution by Matthew works when you can use a fixed increment value (which is perfectly acceptable in my case). However is there a solution when you don't want to fix the size of the increment, but want to adjust it dynamically?</p></li>
</ul>

<p>This is probably a really simple jQuery question, but I couldn't answer it after 10 minutes in the documentation so...</p>
<p>I have a list of checkboxes, and I can get them with the selector <code>'input[type=checkbox]'</code>. I want the user to be able to shift-click and select a range of checkboxes. To accomplish this, I need to get the index of a checkbox in the list, so I can pass that index to <code>.slice(start, end)</code>. How do I get the index when the user clicks a box?</p>

<p>We are now using NHibernate to connect to different database base on where our software is installed. So I am porting many SQL Procedures to Oracle.</p>
<p>SQL Server has a nice function called DateDiff which takes a date part, startdate and enddate.</p>
<p>Date parts examples are day, week, month, year, etc. . . </p>
<p>What is the Oracle equivalent?</p>
<p>I have not found one do I have to create my own version of it?</p>
<p><strong>(update by Mark Harrison)</strong> there are several nice answers that explain Oracle date arithmetic. If you need an Oracle datediff() see Einstein's answer. (I need this to keep spme SQL scripts compatible between Sybase and Oracle.) Note that this question applies equally to Sybase.</p>

<p>I think I might be missing something here. Here is the relevant part of the trigger:</p>
<pre><code> CURSOR columnNames (inTableName IN VARCHAR2) IS
SELECT COLUMN_NAME FROM USER_TAB_COLUMNS WHERE TABLE_NAME = inTableName;
/* Removed for brevity */
OPEN columnNames('TEMP');
</code></pre>
<p>And here is the error message that I'm getting back,</p>
<pre>
27/20 PLS-00306: wrong number or types of arguments in call to 'COLUMNNAMES'
27/2 PL/SQL: Statement ignored
</pre>
<p>If I am understanding the documentation correctly, that should work, but since it is not I must be doing something wrong. Any ideas?</p>
<hr />
<p>@<a href="https://stackoverflow.com/questions/43832/pls-00306-error-on-call-to-cursor#43859">Matthew</a> - I appreciate the help, but the reason that I am confused is because this bit of code isn't working for me and is raising the errors referenced. We have other triggers in the database with code almost exactly the as that so I'm not sure if it is something that I did wrong, or something with how I am trying to store the trigger, etc.</p>
<hr />
<p>@<a href="https://stackoverflow.com/questions/43832/pls-00306-error-on-call-to-cursor#43859">Matthew</a> - Well, now I get to feel embarrassed. I did a copy/paste of the code that you provided into a new trigger and it worked fine. So I went back into the original trigger and tried it and received the error message again, except this time I started to delete stuff out of the trigger and after getting rid of this line,</p>
<pre><code>FOR columnName IN columnNames LOOP
</code></pre>
<p>Things saved fine. So it turns out that where I thought the error was, wasn't actually were the error was.</p>

<p>I have a string that contains the representation of a date. It looks like: </p>
<p><strong>Thu Nov 30 19:00:00 EST 2006</strong></p>
<p>I'm trying to create a Date object using SimpleDateFormat and have 2 problems. </p>
<p>1.) I can't figure out the pattern to hard-code the solution into the SimpleDateFormat constructor</p>
<p>2.) I can't find a way I could parse the string using API to determine the pattern so I could reuse this for different patterns of date output </p>
<p>If anyone knows a solution using API or a custom solution I would greatly appreciate it.</p>

<p>I have a multiple selection SELECT field which I don't want the end user to be able to change the value of. </p>
<p>For UI reasons, I would like to be able to do this without using the disabled="true" attribute. I've tried using onmousedown, onfocus, onclick and setting each to blur or return false but with no success.</p>
<p>Can this be done or am I trying to do the impossible?</p>

<p><strong>Original Question</strong></p>
<p>I want to be able to generate a new (fully valid) MP3 file from an existing MP3 file to be used as a preview -- try-before-you-buy style. The new file should only contain the first <em>n</em> seconds of the track.</p>
<p>Now, I know I could just "chop the stream" at <em>n</em> seconds (calculating from the bitrate and header size) when delivering the file, but this is a bit dirty and a real PITA on a VBR track. I'd like to be able to generate a proper MP3 file.</p>
<p>Anyone any ideas?</p>
<p><strong>Answers</strong></p>
<p>Both <code>mp3split</code> and <code>ffmpeg</code> are both good solutions. I chose ffmpeg as it is commonly installed on linux servers and is also <a href="http://sourceforge.net/project/showfiles.php?group_id=205275&package_id=248632" rel="noreferrer">easily available for windows</a>. Here's some more good command line parameters for generating previews with ffmpeg</p>
<ul>
<li><strong><code>-t <seconds></code></strong> chop after specified number of seconds</li>
<li><strong><code>-y</code></strong> force file overwrite</li>
<li><strong><code>-ab <bitrate></code></strong> set bitrate e.g. <em>-ab 96k</em></li>
<li><strong><code>-ar <rate Hz></code></strong> set sampling rate e.g. <em>-ar 22050</em> for 22.05kHz</li>
<li><strong><code>-map_meta_data <outfile>:<infile></code></strong> copy track metadata from infile to outfile</li>
</ul>
<p>instead of setting -ab and -ar, you can copy the original track settings, as Tim Farley suggests, with:</p>
<ul>
<li><strong><code>-acodec copy</code></strong></li>
</ul>

<p>A <code>.container</code> can contain many <code>.components</code>, and <code>.components</code> themselves can contain <code>.containers</code> (which in turn can contain .components etc. etc.)</p>
<p>Given code like this:</p>
<pre><code>$(".container .component").each(function(){
$(".container", this).css('border', '1px solid #f00');
});
</code></pre>
<p>What do I need to add to the line within the braces to select only the nested <code>.containers</code> that have their <code>width</code> in CSS set to <code>auto</code>? I'm sure it's something simple, but I haven't really used jQuery all that much.</p>

<p>Is it possible to modify the title of the message box the confirm() function opens in JavaScript? </p>
<p>I could create a modal popup box, but I would like to do this as minimalistic as possible.
I would like to do something like this:</p>
<pre><code>confirm("This is the content of the message box", "Modified title");
</code></pre>
<p>The default title in Internet Explorer is "Windows Internet Explorer" and in Firefox it's "[JavaScript-program]." Not very informative. Though I can understand from a browser security stand point that you shouldn't be able to do this.</p>

<p>I'm setting up a server which is on a network behind a firewall and I want programs on this computer to be able to use sendmail to send emails to any email address. We have an SMTP server running on this network (let's call it mailrelay.example.com) which is how we're supposed to get outgoing emails through the firewall.</p>
<p>So how do I configure sendmail to send all mail through mailrelay.example.com? Googling hasn't given me the answer yet, and has only revealed that sendmail configuration is extremely complex and annoying.</p>

<p>Let's say I have a web site for hosting community generated content that targets a very specific set of users. Now, let's say in the interest of fostering a better community I have an off-topic area where community members can post or talk about anything they want, regardless of the site's main theme.</p>
<p>Now, I <em>want</em> most of the content to get indexed by Google. The notable exception is the off-topic content. Each thread has it's own page, but all the threads are listed in the same folder so I can't just exclude search engines from a folder somewhere. It has to be per-page. A traditional robots.txt file would get huge, so how else could I accomplish this?</p>

<p>I want to allow my users to embed their own Flash animations in their posts. Usually the actual file is hosted on some free image hosting site. I wouldn't actually load the flash unless the user clicked a button to play (so that nothing auto-plays on page load). I know people can make some really annoying crap in flash, but I can't find any information about potential <em>serious</em> damage a flash app could cause to the viewer.</p>
<p>Is it unsafe to embed just any flash file from the internets? If so, how can I let users embed innocent animations but still keep out the harmful apps?</p>
<p>edit:</p>
<p>From what I can gather, the most obvious threat is for actionscript to redirect you to a malicious site.</p>
<p>Adobe <a href="http://www.adobe.com/devnet/flashplayer/articles/secure_swf_apps_04.html" rel="nofollow noreferrer">says</a> you can set <strong>allowScriptAccess=never</strong> and <strong>allowNetworking=none</strong> and the swf should have no access to anything outside of itself. <strong>Will this solve all my problems?</strong></p>

<p>Handling multiple merges onto branches in Subversion or CVS is just one of those things that has to be experienced. It is inordinately easier to keep track of branches and merges in Mercurial (and probably any other distributed system) but I don't know why. Does anyone else know?</p>
<p>My question stems from the fact that with Mercurial you can adopt a working practice similar to that of Subversions/CVSs central repository and everything will work just fine. You can do multiple merges on the same branch and you won't need endless scraps of paper with commit numbers and tag names.</p>
<p>I know the latest version of Subversion has the ability to track merges to branches so you don't get quite the same degree of hassle but it was a huge and major development on their side and it still doesn't do everything the development team would like it to do.</p>
<p>There must be a fundamental difference in the way it all works.</p>

<p>I need to diff two log files but ignore the time stamp part of each line (the first 12 characters to be exact). Is there a good tool, or a clever awk command, that could help me out?</p>

<p>Unable to find a SQL diff tool that meets my needs, I am writing my own. Between the INFORMATION_SCHEMA and sys tables, I have a mostly-complete working version. But one thing I can't find in the metadata is the <em>definition</em> of a trigger, you know, the actual SQL code. Am I overlooking something?</p>
<p>Thanks.</p>
<hr>
<p>Thanks, Pete, I didn't know about that!</p>
<p>Scott, I'm working with very basic hosting packages that don't allow remote connections to the DB. I don't know from the specs on RedGate (which I can't afford anyway) whether they provide a workaround for that, and although there are also API's out there (such as the one from Apex), I didn't see the point in investing in a solution that was still going to require more programming on my part. :)</p>
<p>My solution is to drop an ASPX page on the site that acts as a kind of "schema service", returning the collected metadata as XML. I set up a little AJAX app that compares any number of catalog instances to a master and shows the diffs. It's not perfect, but a major step forward for me.</p>
<p>Thanks again!</p>

<p>I'm trying to determine the best way to truncate or drop extra decimal places in SQL without rounding. For example:</p>
<pre><code>declare @value decimal(18,2)
set @value = 123.456
</code></pre>
<p>This will automatically round <code>@value</code> to be <code>123.46</code>, which is good in most cases. However, for this project, I don't need that. Is there a simple way to truncate the decimals I don't need? I know I can use the <code>left()</code> function and convert back to a decimal. Are there any other ways?</p>

What software or modules for Apache are available that will make a daily copy of my access file to make it more manageable?</p>

<p>I am trying to write a regular expression to strip all HTML with the exception of links (the <code><a href</code> and <code></a></code> tags respectively. It does not have to be 100% secure (I am not worried about injection attacks or anything as I am parsing content that has already been approved and published into a <a href="http://en.wikipedia.org/wiki/SWF" rel="noreferrer">SWF</a> movie).</p>
<p>The original "strip tags" regular expression I'm using was <code><(.|\n)+?></code>, and I tried to modify it to <code><([^a]|\n)+?></code>, but that of course will allow any tag that has an <strong>a</strong> in it rather than one that has it in the beginning, with a space.</p>
<p>Not that it should really matter, but in case anyone cares to know I am writing this in <a href="http://en.wikipedia.org/wiki/ActionScript#ActionScript_3.0" rel="noreferrer">ActionScript 3.0</a> for a <a href="http://en.wikipedia.org/wiki/Adobe_Flash" rel="noreferrer">Flash</a> movie.</p>

<p>That's it. If you want to document a function or a class, you put a string just after the definition. For instance:</p>
<pre><code>def foo():
"""This function does nothing."""
pass
</code></pre>
<p>But what about a module? How can I document what a <em>file.py</em> does?</p>

<p>I have connected to a server via SFTP using FileZilla and accepted adding the server's SSH key to the key cache in FileZilla. </p>
<p>How can I extract this cached key to a keyfile so that may use it through other SFTP applications that require a keyfile be made available? </p>
<p>I have not been able to find anything in the FileZilla documentation related to this.</p>

<p>This is a fairly trivial matter, but I'm curious to hear people's opinions on it.</p>
<p>If I have a Dictionary which I'm access through properties, which of these formats would you prefer for the property?</p>
<pre><code>/// <summary>
/// This class's FirstProperty property
/// </summary>
[DefaultValue("myValue")]
public string FirstProperty {
get {
return Dictionary["myKey"];
}
set {
Dictionary["myKey"] = value;
}
</code></pre>
<p>This is probably the typical way of doing it. It's fairly efficient, easy to understand, etc. The only disadvantage is with a longer or more complex key it would be possible to misspell it or change only one instance or something, leading me to this:</p>
<pre><code>/// <summary>
/// This class's SecondProperty property
/// </summary>
[DefaultValue("myValue")]
private const string DICT_MYKEY = "myKey"
public string SecondProperty {
get {
return Dictionary[DICT_MYKEY];
}
set {
Dictionary[DICT_MYKEY] = value;
}
</code></pre>
<p>Which is marginally more complicated, but seems to offer additional safety, and is closer to what I would think of as the "Code Complete" solution. The downside is that when you also have a /// block and a [DefaultValue()] block above the property already, it starts getting a bit crowded up there.</p>
<p>So which do you like better, and why? Does anybody have any better ideas?</p>

<p>What's the best way to extend the User model (bundled with Django's authentication app) with custom fields? I would also possibly like to use the email as the username (for authentication purposes).</p>
<p>I've already seen a <a href="http://scottbarnham.com/blog/2008/08/21/extending-the-django-user-model-with-inheritance/" rel="noreferrer">few</a> <a href="http://www.b-list.org/weblog/2006/jun/06/django-tips-extending-user-model/" rel="noreferrer">ways</a> to do it, but can't decide on which one is the best.</p>

<p>I need to display a variable-length message and allow the text to be selectable. I have made the TextBox ReadOnly which does not allow the text to be edited, but the input caret is still shown. </p>
<p>The blinking input caret is confusing. How do I hide it?</p>

<p>What's the best way to deal with a sharded database in Rails? Should the sharding be handled at the application layer, the active record layer, the database driver layer, a proxy layer, or something else altogether? What are the pros and cons of each?</p>

<p>Like the title says: Can reflection give you the name of the currently executing method.</p>
<p>I'm inclined to guess not, because of the Heisenberg problem. How do you call a method that will tell you the current method without changing what the current method is? But I'm hoping someone can prove me wrong there.</p>
<p><strong>Update:</strong> </p>
<ul>
<li>Part 2: Could this be used to look inside code for a property as well? </li>
<li>Part 3: What would the performance be like?</li>
</ul>
<p><strong>Final Result</strong><br>
I learned about MethodBase.GetCurrentMethod(). I also learned that not only can I create a stack trace, I can create only the exact frame I need if I want. </p>
<p>To use this inside a property, just take a .Substring(4) to remove the 'set_' or 'get_'.</p>

<p>Is there a way to perform a full text search of a subversion repository, including all the history?</p>
<p>For example, I've written a feature that I used somewhere, but then it wasn't needed, so I svn rm'd the files, but now I need to find it again to use it for something else. The svn log probably says something like "removed unused stuff", and there's loads of checkins like that.</p>
<p><strong>Edit 2016-04-15:</strong> Please note that what is asked here by the term "full text search", is to <strong>search the actual diffs of the commit history, and not filenames and/or commit messages</strong>. I'm pointing this out because the author's phrasing above does not reflect that very well - since in his example he might as well be only looking for a filename and/or commit message. Hence a lot of the <code>svn log</code> answers and comments.</p>

<p>A friend of mine told me there was a way to connect two private IPs without using a proxy server. The idea was that both computers connected to a public server and some how the server joined the private connections and won't use any more bandwidth.</p>
<p>Is this true? How's this technique named?</p>

<p>I have a database with two tables (<code>Table1</code> and <code>Table2</code>). They both have a common column <code>[ColumnA]</code> which is an <code>nvarchar</code>. </p>
<p>How can I select this column from both tables and return it as a single column in my result set?</p>
<p>So I'm looking for something like:</p>
<pre><code>ColumnA in Table1:
a
b
c
ColumnA in Table2:
d
e
f
Result set should be:
a
b
c
d
e
f
</code></pre>

<p>I have been told that there is a performance difference between the following code blocks.</p>
<pre><code>foreach (Entity e in entityList)
{
....
}
</code></pre>
<p>and </p>
<pre><code>for (int i=0; i<entityList.Count; i++)
{
Entity e = (Entity)entityList[i];
...
}
</code></pre>
<p>where</p>
<pre><code>List<Entity> entityList;
</code></pre>
<p>I am no CLR expect but from what I can tell they should boil down to basically the same code. Does anybody have concrete (heck, I'd take packed dirt) evidence one way or the other?</p>

<p>Is there a way to track which window currently has keyboard focus. I could handle WM_SETFOCUS for every window but I'm wondering if there's an alternative, simpler method (i.e. a single message handler somewhere).</p>
<p>I could use OnIdle() in MFC and call GetFocus() but that seems a little hacky.</p>

<p>We've got an interesting case where we are trying to determine how different instances of our app were launched. Is there any way for .NET to be able to query another running instance and get the command line parameters passed to that instance? I've not been able to find any way to do it in .NET so far, so I thought I'd check here to see if anyone had done anything like this before.</p>

<p>What is the best algorithm to take array like below:</p>
<p><code>A {0,1,2,3}</code></p>
<p>I expected to order it like array below:</p>
<p><code>B {3,1,0,2}</code> </p>
<p>Any ideas?</p>

<p>This is a php example, but an algorithm for any language would do. What I specifically want to do is bubble up the United States and Canada to the top of the list. Here is an example of the array shortened for brevity. </p>
<pre><code>array(
0 => '-- SELECT --',
1 => 'Afghanistan',
2 => 'Albania',
3 => 'Algeria',
4 => 'American Samoa',
5 => 'Andorra',)
</code></pre>
<p>The id's need to stay intact. So making them -1 or -2 will unfortunately not work.</p>

<p>Are there any good programs for dealing with reading large CSV files? Some of the datafiles I deal with are in the 1 GB range. They have too many lines for Excel to even deal with. Using Access can be a little slow, as you have to actually import them into a database to work with them directly. Is there a program that can open large CSV files and give you a simple spreadsheet layout to help you easily and quickly scan through the data?</p>

<p>Comparing string in C# is pretty simple. In fact there are several ways to do it. I have listed some in the block below. What I am curious about are the differences between them and when one should be used over the others? Should one be avoided at all costs? Are there more I haven't listed? </p>
<pre><code>string testString = "Test";
string anotherString = "Another";
if (testString.CompareTo(anotherString) == 0) {}
if (testString.Equals(anotherString)) {}
if (testString == anotherString) {}
</code></pre>
<p>(Note: I am looking for equality in this example, not less than or greater than but feel free to comment on that as well)</p>

<p>I have a databound TextBox in my application like so: (The type of <code>Height</code> is <code>decimal?</code>)</p>
<pre class="lang-xml prettyprint-override"><code> <TextBox Text="{Binding Height, UpdateSourceTrigger=PropertyChanged,
ValidatesOnExceptions=True,
Converter={StaticResource NullConverter}}" />
</code></pre>
<pre class="lang-cs prettyprint-override"><code> public class NullableConverter : IValueConverter {
public object Convert(object o, Type type, object parameter, CultureInfo culture) {
return o;
}
public object ConvertBack(object o, Type type, object parameter, CultureInfo culture) {
if (o as string == null || (o as string).Trim() == string.Empty)
return null;
return o;
}
}
</code></pre>
<p>Configured this way, any non-empty strings which cannot be converted to decimal result in a validation error which will immediately highlight the textbox. However, the TextBox can still lose focus and remain in an invalid state. What I would like to do is either:</p>
<ol>
<li>Not allow the TextBox to lose focus until it contains a valid value.</li>
<li>Revert the value in the TextBox to the last valid value.</li>
</ol>
<p>What is the best way to do this?</p>
<p><strong>Update:</strong></p>
<p>I've found a way to do #2. I don't love it, but it works:</p>
<pre><code>private void TextBox_LostKeyboardFocus(object sender, RoutedEventArgs e) {
var box = sender as TextBox;
var binding = box.GetBindingExpression(TextBox.TextProperty);
if (binding.HasError)
binding.UpdateTarget();
}
</code></pre>
<p>Does anyone know how to do this better? (Or do #1.)</p>

<p>As an exercise for myself, I was translating a sample program into various languages. Starting in C#, I had a visitor-pattern interface like so:</p>
<pre><code>interface Visitor
{
void Accept(Bedroom x);
void Accept(Bathroom x);
void Accept(Kitchen x);
void Accept(LivingRoom x);
}
</code></pre>
<p>Moving to ruby (or python, or whatever), I no longer get dispatch from the compiler based on type. Should I do the dispatch in the visitor itself?</p>
<pre><code>class Cleaner
def accept(x)
acceptBedroom(x) if Bedroom === x
acceptBathroom(x) if Bathroom === x
acceptKitchen(x) if Kitchen===x
acceptLivingRoom(x) if LivingRoom===x
end
...
</code></pre>
<p>Or should I do the dispatch in the different specializaions of the room:</p>
<pre><code>class Bathroom<Room
def initialize(name)
super(name)
end
def accept(visitor)
visitor.acceptBathroom(self)
end
end
</code></pre>
<p>Or is there another preferred idiom that is used in dynamic languages?</p>

<p>I'm trying to be better about unit testing my code, but right now I'm writing a lot of code that deals with remote systems. SNMP, WMI, that sort of thing. With most classes I can mock up objects to test them, but how do you deal with unit testing a real system? For example, if my class goes out and gets the Win32_LogicalDisk object for a server, how could I possibly unit test it?</p>

<p>I have built a basic data entry application allowing users to browse external content in iframe and enter data quickly from the same page. One of the data variables is the URL.
Ideally I would like to be able to load the iframes current url into a textbox with javascript. I realize now that this is not going to happen due to security issues.</p>
<p>Has anyone done anything on the server side? or know of any .Net browser in browser controls. The ultimate goal is to just give the user an easy method of extracting the url of the page they are viewing in the iframe It doesn't necessarily HAVE to be an iframe, a browser in the browser would be ideal.</p>
<p>Thanks,
Adam</p>

<p>So, I was reading the Google testing blog, and it says that global state is bad and makes it hard to write tests. I believe it--my code is difficult to test right now. So how do I avoid global state?</p>
<p>The biggest things I use global state (as I understand it) for is managing key pieces of information between our development, acceptance, and production environments. For example, I have a static class named "Globals" with a static member called "DBConnectionString." When the application loads, it determines which connection string to load, and populates Globals.DBConnectionString. I load file paths, server names, and other information in the Globals class.</p>
<p>Some of my functions rely on the global variables. So, when I test my functions, I have to remember to set certain globals first or else the tests will fail. I'd like to avoid this.</p>
<p>Is there a good way to manage state information? (Or am I understanding global state incorrectly?)</p>

<p>I am looking for a method of reading emails using Pop3 in C# 2.0. Currently, I am using code found in <a href="http://www.codeproject.com/KB/IP/Pop3MimeClient.aspx?fid=341657" rel="noreferrer">CodeProject</a>. However, this solution is less than ideal.

<p>This is related to <a href="https://stackoverflow.com/questions/43324/can-i-put-an-aspnet-session-id-in-a-hidden-form-field">another question I asked</a>. In summary, I have a special case of a URL where, when a form is POSTed to it, I can't rely on cookies for authentication or to maintain the user's session, but I somehow need to know who they are, and I need to know they're logged in!</p>
<p>I think I came up with a solution to my problem, but it needs fleshing out. Here's what I'm thinking. I create a hidden form field called "username", and place within it the user's username, encrypted. Then, when the form POSTs, even though I don't receive any cookies from the browser, I know they're logged in because I can decrypt the hidden form field and get the username.</p>
<p>The major security flaw I can see is replay attacks. How do I prevent someone from getting ahold of that encrypted string, and POSTing as that user? I know I can use SSL to make it harder to steal that string, and maybe I can rotate the encryption key on a regular basis to limit the amount of time that the string is good for, but I'd really like to find a bulletproof solution. Anybody have any ideas? Does the ASP.Net ViewState prevent replay? If so, how do they do it?</p>
<p><strong>Edit</strong>: I'm hoping for a solution that doesn't require anything stored in a database. Application state would be okay, except that it won't survive an IIS restart or work at all in a web farm or garden scenario. I'm accepting Chris's answer, for now, because I'm not convinced it's even possible to secure this without a database. But if someone comes up with an answer that does not involve the database, I'll accept it!</p>

<p>I have a MemoryStream with the contents of a Font File (.ttf) and I would like to be able to create a FontFamily WPF object from that stream <strong>WITHOUT</strong> writing the contents of the stream to disk. I know this is possible with a System.Drawing.FontFamily but I cannot find out how to do it with System.Windows.Media.FontFamily.</p>
<p>Note: I will only have the stream, so I can't pack it as a resource in the application and because of disk permissions issues, will not be able to write the font file to disk for reference as "content"</p>
<p><strong>UPDATE:</strong></p>
<p>The <a href="https://learn.microsoft.com/en-us/dotnet/api/system.windows.media.fontfamily?view=netframework-4.6.1" rel="nofollow noreferrer">API docs</a> how describe how an application resource can be used, though it is not clear to me whether that is an Embedded resource in the assembly or a file on disk.</p>
<blockquote>
<p>You can use a base URI value when you reference a font that is packaged as part of the application. For example, the base URI value can be a "pack://application" URI, which lets you reference fonts that are packaged as application resources. The following code example shows a font reference that is composed of a base URI value and a relative URI value.</p>

<p>I use Eclipse, Maven, and Java in my development. I use Maven to download dependencies (jar files and javadoc when available) and Maven's eclipse plug-in to generate the .project and .classpath files for Eclipse. When the dependency downloaded does not have attached javadoc I manually add a link for the javadoc in the .classpath file so that I can see the javadoc for the dependency in Eclipse. Then when I run Maven's eclipse plugin to regenerate the .classpath file it of course wipes out that change.</p>
<p>Is there a way to configure Maven's eclipse plug-in to automatically add classpath attributes for javadoc when running Maven's eclipse plug-in? </p>
<p>I'm only interested in answers where the javadoc and/or sources are not provided for the dependency in the maven repository, which is the case most often for me. Using downloadSources and/or downloadJavadocs properties won't help this problem.</p>

<p>I've got a sign up form that requires the user to enter their email and password, both are in two separate text boxes. I want to provide a button that the user can click so that the password (which is masked) will appear in a popup when the user clicks the button.</p>
<p>Currently my JavaScript code for this is as follows:</p>
<pre><code> function toggleShowPassword() {
var button = $get('PASSWORD_TEXTBOX_ID');
var password;
if (button)
{
password = button.value;
alert(password);
button.value = password;
}
}
</code></pre>
<p>The problem is that every time the user clicks the button, the password is cleared in both Firefox and IE. I want them to be able to see their password in clear text to verify without having to retype their password.</p>
<p>My questions are:</p>
<ol>
<li><p>Why does the password field keep getting reset with each button click?</p></li>
<li><p>How can I make it so the password field is NOT cleared once the user has seen his/her password in clear text?</p></li>
</ol>

<p>I have a web application developed with ASP.net and C# that is running on my companies' intranet. Because all the users for this application are all using Microsoft Outlook without exception, I would like for the the application to open up an Outlook message on the client-side. <strong>I understand that Office is designed to be run on the desktop and not from a server, however I have no trouble creating a Word or Excel document on the client-side.</strong> </p>
<p>I have code that instantiates the Outlook object using the Microsoft.Office.Interop.Outlook namespace and Outlook installed on the server. When I try to run the code from the server, I get a DCOM source error message that states "The machine-default permission settings do not grant Local Activation permission for the COM Server application with CLSID {000C101C-0000-0000-C000-000000000046} to the user This security permission can be modified using the Component Services administrative tool." I have modified the permissions using the Component Services tool, but still get this same error. </p>
<p>Is there a way to overcome this or is this a fruitless exercise because Outlook cannot be opened on the client side from the server-side code?</p>
<p>Mailto will not work due to the extreme length that the emails can obtain. Also, the user that sends it needs add in eye-candy to the text for the recipients.</p>

<p>I've got a web application working using VB and Ajax. I'm using updatepanels to avoid the irritating "flicker" on postbacks to the server. </p>
<p>I would like to have a button control defined within the updatepanel itself (tried moving it outside and got some catastrophic error, so left it there) that makes the current panel not visible and a sibling panel visible. This works with the exception that the button must be clicked twice. Not double clicked, but clicked once than clicked again. </p>
<p>In setting breakpoints I discovered the code behind that's attached to the button is actually being executed on the first click, but the panels don't switch as expected. If I click the same button OR worse yet, a different button, the expected behavior of the second panel appearing occurs. However, with the second button being clicked there's an unwanted bonus of a third panel being displayed, the third panel being made visible due to the second button being clicked.</p>
<p>I'm assuming this behavior is due to the updatepanel and its Ajax nature. Is there a way to avoid the second click? Am I misusing the updatepanel? I really wanted to use a modal popup (right out of the AjaxToolKit) but had problems with posting back the data so I opted for this approach. Any insights, assistance, even criticism would be welcome as this has plagued me long enough. Thanks</p>

<p>Our company has multiple domains set up with one website hosted on each of the domains. At this time, each domain has its own authentication which is done via cookies. </p>
<p>When someone logged on to one domain needs to access anything from the other, the user needs to log in again using different credentials on the other website, located on the other domain. </p>
<p>I was thinking of moving towards single sign on (SSO), so that this hassle can be eliminated. I would appreciate any ideas on how this could be achieved, as I do not have any experience in this regard.</p>
<p>Thanks.</p>
<p><strong>Edit:</strong>
The websites are mix of internet (external) and intranet (internal-used within the company) sites.</p>

<p>I keep racking my brain but can't think of a decent way to build the dynamic links that always show the 2 pages around the current, plus the first and last.</p>

<p>I have never used octal numbers in my code nor come across any code that used it (hexadecimal and bit twiddling notwithstanding).</p>
<p>I started programming in C/C++ about 1994 so maybe I'm too young for this? Does older code use octal? C includes support for these by prepending a 0, but where is the code that uses these base 8 number literals?</p>

<p>I would like to be able to add a "message" to a unit test, such that it actually appears within the TestResult.xml file generated by NUnit. For example, this is currently generated:</p>
<pre><code><results>
<test-case name="MyNamespace.Tests.MyTest" executed="True" success="True" time="0.203" asserts="4" />
</results>
</code></pre>
<p>I would like to be able to have an additional attribute (or node as the case may be), such as:</p>
<pre><code><results>
<test-case name="MyNamespace.Tests.MyTest" executed="True" success="True" time="0.203" asserts="4" message="Tested that some condition was met." />
</results>
</code></pre>
<p>The idea is that "message" above would somehow be defined within the test method itself (in my case, generated at run-time). Is there a property somewhere that I'm missing to be able to do something like this?</p>

<p>The code that I want to write is like this:</p>
<pre><code>void MethodOnThreadA()
{
for (;;)
{
// Do stuff
if (ErrorConditionMet)
ThrowOnThread(threadB, new MyException(...));
}
}
void MethodOnThreadB()
{
try
{
for (;;)
{
// Do stuff
}
}
catch (MyException ex)
{
// Do the right thing for this exception.
}
}
</code></pre>
<p>I know I can have thread B periodically check, in thread safe way, to see if a flag has been set by thread A, but that makes the code more complicated. Is there a better mechanism that I can use?</p>
<p>Here is a more fleshed out example of periodically checking:</p>
<pre><code>Dictionary<Thread, Exception> exceptionDictionary = new Dictionary<Thread, Exception>();
void ThrowOnThread(Thread thread, Exception ex)
{
// the exception passed in is going to be handed off to another thread,
// so it needs to be thread safe.
lock (exceptionDictionary)
{
exceptionDictionary[thread] = ex;
}
}
void ExceptionCheck()
{
lock (exceptionDictionary)
{
Exception ex;
if (exceptionDictionary.TryGetValue(Thread.CurrentThread, out ex))
throw ex;
}
}
void MethodOnThreadA()
{
for (;;)
{
// Do stuff
if (ErrorConditionMet)
ThrowOnThread(threadB, new MyException(...));
}
}
void MethodOnThreadB()
{
try
{
for (;;)
{
// Do stuff
ExceptionCheck();
}
}
catch (MyException ex)
{
// Do the right thing for this exception.

<p>I need to write a program that can sift through specially-formatted text files (essentially CSV files with a fixed set of column types that have different delimiters for some columns ... comma in most places, colons in others) to search for formatting errors. I figure regular expressions will be the way to go.</p>
<p>The question: Is there a good regex library for VB6?</p>
<p>Thank you!</p>
<p>Edit: Holy crap, 3 responses in under an hour. Thanks a ton, folks! I've heard such good things about Regex Buddy from Jeff's postings / podcasting, that I will have to take a look.</p>

<p>In C++, what alternatives do I have for exposing a collection, from the point of view of performance and data integrity?</p>
<p>My problem is that I want to return an internal list of data to the caller, but I don't want to generate a copy. Thant leaves me with either returning a reference to the list, or a pointer to the list. However, I'm not crazy about letting the caller change the data, I just want to let it read the data. </p>
<ul>
<li>Do I have to choose between performance and data integrity? </li>
<li>If so, is in general better to go one way or is it particular to the case? </li>
<li>Are there other alternatives?</li>
</ul>

<p>Ruby setters—whether created by <code>(c)attr_accessor</code> or manually—seem to be the only methods that need <code>self.</code> qualification when accessed within the class itself. This seems to put Ruby alone the world of languages:</p>
<ul>
<li>All methods need <code>self</code>/<code>this</code> (like Perl, and I think Javascript)</li>
<li>No methods require <code>self</code>/<code>this</code> is (C#, Java)</li>
<li>Only setters need <code>self</code>/<code>this</code> (Ruby?)</li>
</ul>
<p>The best comparison is C# vs Ruby, because both languages support accessor methods which work syntactically just like class instance variables: <code>foo.x = y</code>, <code>y = foo.x</code> . C# calls them properties.</p>
<p>Here's a simple example; the same program in Ruby then C#:</p>
<pre><code>class A
def qwerty; @q; end # manual getter
def qwerty=(value); @q = value; end # manual setter, but attr_accessor is same
def asdf; self.qwerty = 4; end # "self." is necessary in ruby?
def xxx; asdf; end # we can invoke nonsetters w/o "self."
def dump; puts "qwerty = #{qwerty}"; end
end
a = A.new
a.xxx
a.dump
</code></pre>
<p>take away the <code>self.qwerty =()</code> and it fails (Ruby 1.8.6 on Linux & OS X). Now C#:</p>
<pre><code>using System;
public class A {
public A() {}
int q;
public int qwerty {
get { return q; }
set { q = value; }
}
public void asdf() { qwerty = 4; } // C# setters work w/o "this."
public void xxx() { asdf(); } // are just like other methods
public void dump() { Console.WriteLine("qwerty = {0}", qwerty); }
}
public class Test {
public static void Main() {
A a = new A();
a.xxx();
a.dump();
}
}
</code></pre>
<p>Question: Is this true? Are there other occasions besides setters where self is necessary? I.e., are there other occasions where a Ruby method <em>cannot</em> be invoked <em>without</em> self?</p>
<p>There are certainly lots of cases where self <em>becomes</em> necessary. This is not unique to Ruby, just to be clear:</p>
<pre><code>using System;
public class A {
public A() {}
public int test { get { return 4; }}
public int useVariable() {
int test = 5;
return test;
}
public int useMethod() {
int test = 5;
return this.test;
}
}
public class Test {
public static void Main() {
A a = new A();
Console.WriteLine("{0}", a.useVariable()); // prints 5
Console.WriteLine("{0}", a.useMethod()); // prints 4
}
}
</code></pre>
<p>Same ambiguity is resolved in same way. But while subtle I'm asking about the case where </p>
<ul>
<li>A method <em>has</em> been defined, and</li>
<li><em>No</em> local variable has been defined, and</li>
</ul>
<p>we encounter</p>
<pre><code>qwerty = 4
</code></pre>
<p>which is ambiguous—is this a method invocation or an new local variable assignment?</p>
<hr>
<p>@Mike Stone</p>
<p>Hi! I understand and appreciate the points you've made and your
example was great. Believe me when I say, if I had enough reputation,
I'd vote up your response. Yet we still disagree: </p>
<ul>
<li>on a matter of semantics, and</li>
<li>on a central point of fact</li>
</ul>
<p>First I claim, not without irony, we're having a semantic debate about the
meaning of 'ambiguity'.</p>
<p>When it comes to parsing and programming language semantics (the subject
of this question), surely you would admit a broad spectrum of the notion
'ambiguity'. Let's just adopt some random notation: </p>
<ol>
<li>ambiguous: lexical ambiguity (lex must 'look ahead')</li>
<li>Ambiguous: grammatical ambiguity (yacc must defer to parse-tree analysis)</li>
<li>AMBIGUOUS: ambiguity knowing everything at the moment of execution</li>
</ol>
<p>(and there's junk between 2-3 too). All these categories are resolved by
gathering more contextual info, looking more and more globally. So when you
say,</p>
<blockquote>
<p>"qwerty = 4" is UNAMBIGUOUS in C#
when there is no variable defined...</p>
</blockquote>
<p>I couldn't agree more. But by the same token, I'm saying </p>
<blockquote>
<p>"qwerty = 4" is un-Ambiguous in ruby
(as it now exists)</p>
<p>"qwerty = 4" is Ambiguous in C#</p>
</blockquote>
<p>And we're not yet contradicting each other. Finally, here's where we really
disagree: Either ruby could or could not be implemented without any further
language constructs such that,</p>
<blockquote>
<p>For "qwerty = 4," ruby UNAMBIGUOUSLY
invokes an existing setter if there<br>
is no local variable defined</p>
</blockquote>
<p>You say no. I say yes; another ruby could exist which behaves exactly like
the current in every respect, <em>except</em> "qwerty = 4" defines a new
variable when no setter and no local exists, it invokes the setter if one
exists, and it assigns to the local if one exists. I fully accept that I
could be wrong. In fact, a reason why I might be wrong would be interesting.</p>
<p>Let me explain.</p>
<p>Imagine you are writing a new OO language with accessor methods looking
like instances vars (like ruby & C#). You'd probably start with
conceptual grammars something like:</p>
<pre><code> var = expr // assignment
method = expr // setter method invocation
</code></pre>
<p>But the parser-compiler (not even the runtime) will puke, because even after
all the input is grokked there's no way to know which grammar is pertinent.
You're faced which a classic choice. I can't be sure of the details, but
basically ruby does this:</p>
<pre><code> var = expr // assignment (new or existing)
// method = expr, disallow setter method invocation without .
</code></pre>
<p>that is why it's un-Ambiguous, while and C# does this:</p>
<pre><code> symbol = expr // push 'symbol=' onto parse tree and decide later
// if local variable is def'd somewhere in scope: assignment
// else if a setter is def'd in scope: invocation
</code></pre>
<p>For C#, 'later' is still at compile time.</p>
<p>I'm sure ruby could do the same, but 'later' would have to be at runtime, because
as ben points out you don't know until the statement is executed which case
applies.</p>
<p>My question was never intended to mean "do I really need the 'self.'?" or "what
potential ambiguity is being avoided?" Rather I wanted to know why was this
particular choice made? Maybe it's not performance. Maybe it just got the job
done, or it was considered best to always allow a 1-liner local to override a
method (a pretty rare case requirement) ...</p>
<p>But I'm sort of suggesting that the most dynamical language might be the one which
postpones this decision the longest, and chooses semantics based on the most contextual
info: so if you have no local and you defined a setter, it would use the setter. Isn't
this why we like ruby, smalltalk, objc, because method invocation is decided at runtime,
offering maximum expressiveness?</p>

<p>How can I go about caching just those controls?</p>

<p>Ok, so my method in my webservice requires a type to be passed, it is called in the ServiceMethod property of the AutoCompleteExtender, I am fuzzy about how I should do that so I called it like this:</p>
<pre><code>ServiceMethod="DropDownLoad<<%=(typeof)subCategory%>>"
</code></pre>
<p>where subCategory is a page property that looks like this:</p>
<pre><code>protected SubCategory subCategory
{
get
{
var subCategory = NHibernateObjectHelper.LoadDataObject<SubCategory>(Convert.ToInt32(Request.QueryString["SCID"]));
return subCategory;
}
}
</code></pre>

<p>I'm sending mail from my C# Application, using the SmtpClient. Works great, but I have to decide if I want to send the mail as Plain Text or HTML. I wonder, is there a way to send both? I think that's called multipart.</p>
<p>I googled a bit, but most examples essentially did not use SmtpClient but composed the whole SMTP-Body themselves, which is a bit "scary", so I wonder if something is built in the .net Framework 3.0?</p>
<p>If not, is there any really well used/robust Third Party Library for sending e-Mails?</p>

<p>What would be your preferred way to concatenate strings from a sequence such that between every two consecutive pairs a comma is added. That is, how do you map, for instance, <code>['a', 'b', 'c']</code> to <code>'a,b,c'</code>? (The cases <code>['s']</code> and <code>[]</code> should be mapped to <code>'s'</code> and <code>''</code>, respectively.)</p>
<p>I usually end up using something like <code>''.join(map(lambda x: x+',',l))[:-1]</code>, but also feeling somewhat unsatisfied.</p>

<p>What's the best way to implement a SQL script that will grant select, references, insert, update, and delete permissions to a database role on all the user tables in a database?</p>
<p>Ideally, this script could be run multiple times, as new tables were added to the database. SQL Server Management Studio generates scripts for individual database objects, but I'm looking for more of a "fire-and-forget" script.</p>

<p>Scenario: You have an ASP.Net webpage that should display the next image in a series of images. If 1.jpg is currently loaded, the refresh should load 2.jpg.<br>
Assuming I would use this code, where do you get the current images name.</p>
<pre><code>string currImage = MainPic.ImageUrl.Replace(".jpg", "");
currImage = currImage.Replace("~/Images/", "");
int num = (Convert.ToInt32(currImage) + 1) % 3;
MainPic.ImageUrl = "~/Images/" + num.ToString() + ".jpg";
</code></pre>
<p>The problem with the above code is that the webpage used is the default site with the image set to 1.jpg, so the loaded image is always 2.jpg.<br>
So in the process of loading the page, is it possible to pull the last image used from the pages properties?</p>

<p>I'm on .NET 2.0, running under Medium Trust (so <a href="http://msdn.microsoft.com/en-us/library/system.timezoneinfo.aspx" rel="nofollow noreferrer">TimeZoneInfo</a> and the Registry are not allowed options). I'm asking the user for two dates and a time zone, and would really love to be able to automatically determine whether I need to adjust the time zone for DST. </p>
<p>This probably isn't even a valid scenario unless I have some <em>very</em> robust support, a la <a href="http://msdn.microsoft.com/en-us/library/system.timezoneinfo.aspx" rel="nofollow noreferrer">TimeZoneInfo</a>, to differentiate between all of the different varieties of Time Zones in the first place.</p>

<p>We're currently building an application that executes a number of external tools. We often have to pass information entered into our system by users to these tools.</p>
<p>Obviously, this is a big security nightmare waiting to happen.</p>
<p>Unfortunately, we've not yet found any classes in the .NET Framework that execute command line programs while providing the same kind of guards against injection attacks as the IDbCommand objects do for databases.</p>
<p>Right now, we're using a very primitive string substitution which I suspect is rather insufficient:</p>
<blockquote>
<pre><code>protected virtual string Escape(string value)
{
return value
.Replace(@"\", @"\\")
.Replace(@"$", @"\$")
.Replace(@"""", @"\""")
.Replace("`", "'")
;
}
</code></pre>
</blockquote>
<p>What do you guys do to prevent command-line injection attacks? We're planning to implement a regex that is very strict and only allows a very small subset of characters through, but I was wondering if there was a better way.</p>
<p>Some clarifications:</p>
<ul>
<li>Some of these tools do not have APIs we can program against. If they did, we wouldn't be having this problem.</li>
<li>The users don't pick tools to execute, they enter meta-data which the tools we've chosen use (for example, injecting meta data such as copyright notices into target files). </li>
</ul>
