<p>Is there a performance hit if we use a loop instead of recursion or vice versa in algorithms where both can serve the same purpose? Eg: Check if the given string is a palindrome.
I have seen many programmers using recursion as a means to show off when a simple iteration algorithm can fit the bill.
Does the compiler play a vital role in deciding what to use?</p>

<p>I'm a Java-developer toying with Ruby, and loving it. I have understood that because of Ruby's metaprogramming facilities my unit-tests become much cleaner and I don't need nasty mocking frameworks. I have a class which needs the <code>File</code> class's services and in my test I don't want to touch my real filesystem. In Java I would use some virtual file system for easier "seams" to pass fake-objects in but in Ruby that's obviously overkill. What I come up seems already really nice compared to the Java-world. In my class under test I have an optional constructor parameter: </p>
<pre><code>def initialize(file_class=File)
</code></pre>
<p>When I need to open files within my class, I can then do this:</p>
<pre><code>@file_class.open(filename)
</code></pre>
<p>And the call goes to either the real File-class, or in case of my unit-test, it goes to a fake-class which doesn't touch the filesystem. I know there must be a better way to do this with metaprogramming?</p>

<p>I recently came across an issue with Windows 2003 (apparently it also exists in other versions too), where if an SSL/TLS server is requesting client certificate authentication and it has more than 16KB of trusted certificate DNs, Internet Explorer (or any other app that uses schannel.dll) is unable to complete the SSL handshake. (In a nutshell, the server breaks the message into chunks of 2^14 bytes, as per RFC 2246 sec. 6.2.1, but Schannel wasn't written to support that. I've gotten confirmation from Microsoft support that this is a flaw in Schannel and that they're considering fixing it in a future release.)</p>
<p>So I'm trying to find a way to easily parse through my trusted certificates (I use Apache as my server, so all of them are in PEM format) to get the total ASN.1-format length of the DNs (which is how they get sent over the wire during the handshake), and thereby see if I'm getting too close to the limit. I haven't yet been able to find a way to do this, though: the OpenSSL asn1parse function comes close, but it doesn't seem to provide a way to get the ASN.1 sequence for just the issuer name, which is what I need.</p>
<p>Any suggestions?</p>

<p>Visual Studio solutions contain two types of hidden user files. One is the solution <code>.suo</code> file which is a binary file. The other is the project <code>.user</code> file which is a text file. Exactly what data do these files contain?</p>
<p>I've also been wondering whether I should add these files to source control (Subversion in my case). If I don't add these files and another developer checks out the solution, will Visual Studio automatically create new user files?</p>

<p>here is what a I'm doing: </p>
<pre><code>object ReturnMatch(System.Type type)
{
foreach(object obj in myObjects)
{
if (obj == type)
{
return obj;
}
}
}
</code></pre>
<p>However, if obj is a subclass of <code>type</code>, it will not match. But I would like the function to return the same way as if I was using the operator <code>is</code>.</p>
<p>I tried the following, but it won't compile:</p>
<pre><code>if (obj is type) // won't compile in C# 2.0
</code></pre>
<p>The best solution I came up with was:</p>
<pre><code>if (obj.GetType().Equals(type) || obj.GetType().IsSubclassOf(type))
</code></pre>
<p>Isn't there a way to use operator <code>is</code> to make the code cleaner?</p>

<p>A tutorial I have on Regex in python explains how to use the re module in python, I wanted to grab the URL out of an A tag so knowing Regex I wrote the correct expression and tested it in my regex testing app of choice and ensured it worked. When placed into python it failed:</p>
<pre><code>result = re.match("a_regex_of_pure_awesomeness", "a string containing the awesomeness")
# result is None`
</code></pre>
<p>After much head scratching I found out the issue, it automatically expects your pattern to be at the start of the string. I have found a fix but I would like to know how to change:</p>
<pre><code>regex = ".*(a_regex_of_pure_awesomeness)"
</code></pre>
<p>into</p>
<pre><code>regex = "a_regex_of_pure_awesomeness"
</code></pre>
<p>Okay, it's a standard URL regex but I wanted to avoid any potential confusion about what I wanted to get rid of and possibly pretend to be funny.</p>

<p>How should I store (and present) the text on a website intended for worldwide use, with several languages? The content is mostly in the form of 500+ word articles, although I will need to translate tiny snippets of text on each page too (such as "print this article" or "back to menu").</p>
<p>I know there are several CMS packages that handle multiple languages, but I have to integrate with our existing ASP systems too, so I am ignoring such solutions.</p>
<p>One concern I have is that Google should be able to find the pages, even for foreign users. I am less concerned about issues with processing dates and currencies.</p>
<p>I worry that, left to my own devices, I will invent a way of doing this which work, but eventually lead to disaster! I want to know what professional solutions you have actually used on real projects, not untried ideas! Thanks very much.</p>
<hr>
<p>I looked at RESX files, but felt they were unsuitable for all but the most trivial translation solutions (I will elaborate if anyone wants to know).</p>
<p>Google will help me with translating the text, but not storing/presenting it.</p>
<p>Has anyone worked on a multi-language project that relied on their own code for presentation?</p>
<hr>
<p>Any thoughts on serving up content in the following ways, and which is best?</p>
<ul>
<li><a href="http://www.website.com/text/view.asp?id=12345&lang=fr" rel="nofollow noreferrer">http://www.website.com/text/view.asp?id=12345&lang=fr</a></li>
<li><a href="http://www.website.com/text/12345/bonjour_mes_amis.htm" rel="nofollow noreferrer">http://www.website.com/text/12345/bonjour_mes_amis.htm</a></li>
<li><a href="http://fr.website.com/text/12345" rel="nofollow noreferrer">http://fr.website.com/text/12345</a></li>

<p>I have a nullable property, and I want to return a null value. How do I do that in VB.NET ?</p>
<p>Currently I use this solution, but I think there might be a better way.</p>
<pre><code> Public Shared ReadOnly Property rubrique_id() As Nullable(Of Integer)
Get
If Current.Request.QueryString("rid") <> "" Then
Return CInt(Current.Request.QueryString("rid"))
Else
Return (New Nullable(Of Integer)).Value
End If
End Get
End Property
</code></pre>

<p><strong>Problem</strong></p>
<p>I need to redirect some short convenience URLs to longer actual URLs. The site in question uses a set of subdomains to identify a set of development or live versions.</p>
<p>I would like the URL to which certain requests are redirected to include the HTTP_HOST such that I don't have to create a custom .htaccess file for each host.</p>
<p><strong>Host-specific Example (snipped from .htaccess file)</strong></p>
<pre><code>Redirect /terms http://support.dev01.example.com/articles/terms/
</code></pre>
<p>This example works fine for the development version running at dev01.example.com. If I use the same line in the main .htaccess file for the development version running under dev02.example.com I'd end up being redirected to the wrong place.</p>
<p><strong>Ideal rule (not sure of the correct syntax)</strong></p>
<pre><code>Redirect /terms http://support.{HTTP_HOST}/articles/terms/
</code></pre>
<p>This rule does not work and merely serves as an example of what I'd like to achieve. I could then use the exact same rule under many different hosts and get the correct result.</p>
<p><strong>Answers?</strong></p>
<ul>
<li>Can this be done with mod_alias or does it require the more complex mod_rewrite?</li>
<li>How can this be achieved using mod_alias or mod_rewrite? I'd prefer a mod_alias solution if possible.</li>
</ul>
<p><strong>Clarifications</strong></p>
<p>I'm not staying on the same server. I'd like:</p>
<ul>
<li>http://<strong>example.com</strong>/terms/ -> <a href="http://support" rel="nofollow noreferrer">http://support</a>.<strong>example.com</strong>/articles/terms/</li>
<li><a href="https://secure" rel="nofollow noreferrer">https://secure</a>.<strong>example.com</strong>/terms/ -> <a href="http://support" rel="nofollow noreferrer">http://support</a>.<strong>example.com</strong>/articles/terms/</li>
<li>http://<strong>dev.example.com</strong>/terms/ -> <a href="http://support" rel="nofollow noreferrer">http://support</a>.<strong>dev.example.com</strong>/articles/terms/</li>
<li><a href="https://secure" rel="nofollow noreferrer">https://secure</a>.<strong>dev.example.com</strong>/terms/ -> <a href="http://support" rel="nofollow noreferrer">http://support</a>.<strong>dev.example.com</strong>/articles/terms/</li>
</ul>
<p>I'd like to be able to use the same rule in the .htaccess file on both example.com and dev.example.com. In this situation I'd need to be able to refer to the HTTP_HOST as a variable rather than specifying it literally in the URL to which requests are redirected.</p>
<p>I'll investigate the HTTP_HOST parameter as suggested but was hoping for a working example.</p>

<p>Can anyone tell me what exactly does this Java code do?</p>
<pre><code>SecureRandom random = SecureRandom.getInstance("SHA1PRNG");
byte[] bytes = new byte[20];
synchronized (random)
{
random.nextBytes(bytes);
}
return Base64.encode(bytes);
</code></pre>
<hr>
<p>Step by step explanation will be useful so that I can recreate this code in VB. Thanks</p>

Can this be done without creating a custom editor class?</p>

<p>How would you create a database in Microsoft Access that is searchable only by certain fields and controlled by only a few (necessary) text boxes and check boxes on a form so it is easy to use - no difficult queries?</p>
<p>Example:
You have several text boxes and several corresponding check boxes on a form, and when the check box next to the text box is checked, the text box is enabled and you can then search by what is entered into said text box</p>
<p>(Actually I already know this, just playing stackoverflow jeopardy, where I ask a question I know the answer just to increase the world's coding knowledge! answer coming in about 5 mins)</p>

<p>I am playing with Microsoft's TreeView control and I am trying to force a data update of some sorts while editing a node's label, similar to UpdateData for a grid.</p>
<p>Basically, in my editor, I have a Save button and this TreeView control: what I want is when I am editing a node's label in the TreeView, if I click on the Save button I want to be able to commit the node's label I was editing.</p>

<p>Is there a good way to find out which exceptions a procedure/function can raise in Delphi (including it's called procedures/functions)? </p>
<p>In Java you always have to declare which exceptions that can be thrown, but this is not the case in Delphi, which could lead to unhandled exceptions. </p>
<p>Are there any code analysis tools that detects unhandled exceptions?</p>

<p>I'm kind of interested in getting some feedback about this technique I picked up from somewhere.</p>
<p>I use this when a function can either succeed or fail, but you'd like to get more information about why it failed. A standard way to do this same thing would be with exception handling, but I often find it a bit over the top for this sort of thing, plus PHP4 does not offer this.</p>
<p>Basically the technique involves returning true for success, and <em>something</em> which <em>equates</em> to false for failure. Here's an example to show what I mean:</p>
<pre><code>define ('DUPLICATE_USERNAME', false);
define ('DATABASE_ERROR', 0);
define ('INSUFFICIENT_DETAILS', 0.0);
define ('OK', true);
function createUser($username) {
// create the user and return the appropriate constant from the above
}
</code></pre>
<p>The beauty of this is that in your calling code, if you don't care WHY the user creation failed, you can write simple and readable code:</p>
<pre><code>if (createUser('fred')) {
// yay, it worked!
} else {
// aww, it didn't work.
}
</code></pre>
<p>If you particularly want to check why it didn't work (for logging, display to the user, or do whatever), use identity comparison with ===</p>
<pre><code>$status = createUser('fred');
if ($status) {
// yay, it worked!
} else if ($status === DUPLICATE_USERNAME) {
// tell the user about it and get them to try again.
} else {
// aww, it didn't work. log it and show a generic error message? whatever.
}
</code></pre>
<p>The way I see it, the benefits of this are that it is a normal expectation that a successful execution of a function like that would return true, and failure return false.</p>
<p>The downside is that you can only have <code>7 "error" return values: false, 0, 0.0, "0", null, "", and (object) null.</code> If you forget to use identity checking you could get your program flow all wrong. Someone else has told me that using constants like an <code>enum</code> where they all equate to false is <code>"ick"</code>.</p>
<hr>
<p>So, to restate the question: how acceptable is a practise like this? Would you recommend a different way to achieve the same thing? </p>

<p>I have an app that I've written in C#/WinForms (<a href="http://www.thekbase.com" rel="nofollow noreferrer" title="TheKBase">my little app</a>). To make it cross-platform, I'm thinking of redoing it in Adobe AIR. Are there any arguments in favor of WinForms as a cross-platform app? Is there a cross-platform future for Winforms (e.g., Mono, etc.)? Suggestions for cross-platform UI development?</p>
<p>By cross-platform I mean, currently, Mac OSX, Windows and Linux.</p>
<p>This question was <a href="https://stackoverflow.com/questions/116468/winforms-for-mono-on-mac-linux-and-pc-redux">asked again and answered with better success</a>.</p>

<p>I've got a C++ program that uses SQLite. I want to store the SQL queries in a separate file -- a plain-text file, <em>not</em> a source code file -- but embed that file in the executable file like a resource.</p>
<p>(This has to run on Linux, so I can't store it as an actual resource as far as I know, though that would be perfect if it were for Windows.)</p>
<p>Is there any simple way to do it, or will it effectively require me to write my own resource system for Linux? (Easily possible, but it would take a lot longer.)</p>

<p>I need to create a batch file which starts multiple console applications in a Windows .cmd file. This can be done using the start command.</p>
<p>However, the command has a path in it. I also need to pass paramaters which have spaces as well. How to do this?</p>
<p>E.g. batch file</p>
<pre><code>start "c:\path with spaces\app.exe" param1 "param with spaces"
</code></pre>

<p>Has anyone written an 'UnFormat' routine for Delphi?</p>
<p>What I'm imagining is the <em>inverse</em> of <em>SysUtils.Format</em> and looks something like this </p>
<p>UnFormat('a number %n and another %n',[float1, float2]); </p>
<p>So you could unpack a string into a series of variables using format strings.</p>
<p>I've looked at the 'Format' routine in SysUtils, but I've never used assembly so it is meaningless to me.</p>

<p>Let me start by saying that I do not advocate this approach, but I saw it recently and I was wondering if there was a name for it I could use to point the guilty party to. So here goes.</p>
<p>Now you have a method, and you want to return a value. You <em>also</em> want to return an error code. Of course, exceptions are a much better choice, but for whatever reason you want an error code instead. Remember, I'm playing devil's advocate here. So you create a generic class, like this:</p>
<pre><code>class FunctionResult<T>
{
public T payload;
public int result;
}
</code></pre>
<p>And then declare your functions like this:</p>
<pre><code>FunctionResult<string> MyFunction()
{
FunctionResult<string> result;
//...
return result;
}
</code></pre>
<p>One variation on this pattern is to use an enum for the error code instead of a string. Now, back to my question: is there a name for this, and if so what is it?</p>

<p>For example which is better:</p>
<pre><code>select * from t1, t2 where t1.country='US' and t2.country=t1.country and t1.id=t2.id
</code></pre>
<p>or</p>
<pre><code>select * from t1, t2 where t1.country'US' and t2.country='US' and t1.id=t2.id
</code></pre>
<p>better as in less work for the database, faster results.</p>
<p><strong>Note:</strong> Sybase, and there's an index on both tables of <code>country+id</code>.</p>

<p>I have a svn repository, R, that depends on a library, l, in another repository.</p>
<p>The goal is that when someone checks out R, they also check out l. We want l to still be in its own repository so that l can be updated without dependence on R.</p>
<p>I don't know much about external svn links, but I believe that when depending on a svn-based library one can link to it externally, 'ext'.</p>
<p>If l is in a git repository, can I do something similar? I'd like to preserve the goal stated above.</p>

<p>Problem (simplified to make things clearer):</p>
<ul>
1. there is one statically-linked static.lib that has a function that increments:
<pre><code>
extern int CallCount = 0;
int TheFunction()
{
void *p = &CallCount;
printf("Function called");
return CallCount++;
}
</code></pre>
2. static.lib is linked into a managed C++/CLI managed.dll that wraps TheFunction method:
<pre><code>
int Managed::CallLibFunc()
{
return TheFunction();
}
</code></pre>
3. Test app has a reference to managed.dll and creates multiple domains that call C++/CLI wrapper:
<pre><code>
static void Main(string[] args)
{
Managed c1 = new Managed();
int val1 = c1.CallLibFunc();
// value is zero
AppDomain ad = AppDomain.CreateDomain("NewDomain");
Managed c = ad.CreateInstanceAndUnwrap(a.FullName, typeof(Managed).FullName) as Managed;
int val2 = c.CallLibFunc();
// value is one
}
</code></pre>
</ul>
<p>Question:</p>
<p>Based on what I have read in Essential .NET Vol1 The CLR by Don Box, I would expect val2 to be zero since a brand new copy of managed.dll/static.lib is loaded when CreateInstanceAndUnwrap is called. Am I misunderstanding what is happening? The static library does not seem to be respecting the appdomain boundaries since it's unmanaged code. Is there a way to get around this issue other than by creating a brand new process for instantiating Managed?</p>
<p>Thank you very much everyone!</p>

<p>I'd like to use a different icon for the demo version of my game, and I'm building the demo with a different build config than I do for the full verison, using a preprocessor define to lockout some content, use different graphics, etc. Is there a way that I can make Visual Studio use a different icon for the app Icon in the demo config but continue to use the regular icon for the full version's config?</p>

<p>Imagine this directory structure:</p>
<pre><code>app/
__init__.py
sub1/
__init__.py
mod1.py
sub2/
__init__.py
mod2.py
</code></pre>
<p>I'm coding <code>mod1</code>, and I need to import something from <code>mod2</code>. How should I do it? </p>
<p>I tried <code>from ..sub2 import mod2</code> but I'm getting an "Attempted relative import in non-package".</p>
<p>I googled around but found only "<code>sys.path</code> manipulation" hacks. Isn't there a clean way? </p>
<hr>
<p>Edit: all my <code>__init__.py</code>'s are currently empty </p>
<p>Edit2: I'm trying to do this because sub2 contains classes that are shared across sub packages (<code>sub1</code>, <code>subX</code>, etc.).</p>
<p>Edit3: The behaviour I'm looking for is the same as described in <a href="http://www.python.org/dev/peps/pep-0366/" rel="noreferrer">PEP 366</a> (thanks John B)</p>

<pre><code>[{'name': 'Homer', 'age': 39}, {'name': 'Bart', 'age': 10}]

<p>When sorted by <code>name</code>, it should become:</p>
<pre><code>[{'name': 'Bart', 'age': 10}, {'name': 'Homer', 'age': 39}]

<p>I am just starting to learn javascript, so I don't have the skills to figure out what I assume is a trivial problem.</p>
<p>I'm working with a Wordpress blog that serves as a FAQ for our community and I am trying to pull together some tools to make managing the comments easier. <a href="https://stackoverflow.com/users/4465/levik">Internet Duct Tape's Greasemonkey tools, like Comment Ninja</a>, are helpful for most of it, but I want to be able to get a list of all the IP addresses that we're getting comments from in order to track trends and so forth.</p>
<p>I just want to be able to select a bunch of text on the comments page and click a bookmarklet (<a href="https://stackoverflow.com/users/8119/jacob">http://bookmarklets.com</a>) in Firefox that pops up a window listing all the IP addresses found in the selection.</p>
<p><strong>Update:</strong></p>
<p>I kind of combined a the answers from <a href="https://stackoverflow.com/users/4465/levik">levik</a> and <a href="https://stackoverflow.com/users/8119/jacob">Jacob</a> to come up with this:</p>
<pre><code>javascript:ipAddresses=document.getSelection().match(/\b\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}\b/g).join("<br>");newWindow=window.open('', 'IP Addresses in Selection', 'innerWidth=200,innerHeight=300,scrollbars');newWindow.document.write(ipAddresses)
</code></pre>
<p>The difference is that instead of an <em>alert</em> message, as in levik's answer, I open a new window similar to Jacob's answer. The <em>alert</em> doesn't provide scroll bars which can be a problem for pages with many IP addresses. However, I needed the list to be vertical, unlike Jacob's solution, so I used the hint from levik's to make a <em><br></em> for the join instead of levik's <em>\n</em>. </p>
<p>Thanks for all the help, guys.</p>

<p>C++ just sucks too much of my time by making me micro-manage my own memory, making me type far too much (hello <code>std::vector<Thingy>::const_iterator it = lotsOfThingys.begin()</code>), and boring me with long compile times. What's the single best alternative for serious real-time graphics programming? Garbage collection is a must (as is the ability to avoid its use when necessary), and speed must be competitive with C++. A reasonable story for accessing C libs is also a must.</p>
<p>(Full disclosure: I have my own answer to this, but I'm interested to see what others have found to be good alternatives to C++ for real-time graphics work.)</p>
<p><strong>Edit:</strong> Thanks everyone for the thoughtful replies. Given that there's really no "right" answer to this question I won't be selecting any particular answer. Besides I'd just pick the language I happen to like as a C++ alternative, which wouldn't really be fair.</p>

<p>Using Django's built in models, how would one create a triple-join between three models.</p>
<p>For example:</p>
<ul>
<li>Users, Roles, and Events are the models.</li>
<li>Users have many Roles, and Roles many Users. (ManyToMany)</li>
<li>Events have many Users, and Users many Events. (ManyToMany)</li>
<li>But for any given Event, any User may have only one Role.</li>
</ul>
<p>How can this be represented in the model?</p>

<p>I want to simulate a 'Web 2.0' Lightbox style UI technique in a <a href="http://en.wikipedia.org/wiki/Windows_Forms" rel="noreferrer">Windows Forms</a> application. That is, to draw attention to some foreground control by 'dimming' all other content in the client area of a window. </p>
<p>The obvious solution is to create a control that is simply a partially transparent rectangle that can be docked to the client area of a window and brought to the front of the Z-Order. It needs to act like a dirty pain of glass through which the other controls can still be seen (and therefore continue to paint themselves). Is this possible? </p>
<p>I've had a good hunt round and tried a few techniques myself but thus far have been unsuccessful.
If it is not possible, what would be another way to do it?</p>
<p>See: <a href="http://www.useit.com/alertbox/application-design.html" rel="noreferrer">http://www.useit.com/alertbox/application-design.html</a> (under the Lightbox section for a screenshot to illustrate what I mean.)</p>

<p>I am creating an installer in IzPack. It is quite large, and I have broken up my XML files appropriately using <xinclude> and <xfragment> tags. Unfortunately, IzPack does not combine them together when you build your installer. This requires you to package the files with the installer, which just won't work. </p>
<p>I was about to start writing a tool in Java to load the XML files and combine them, but I don't want to go reinventing the wheel. </p>
<p>Do the Java XML libraries provide native handling of xinclude? A google didn't seem to turn up much. </p>
<p>Not a big deal if I have to write this myself, just wanted to check with you guys. Thanks.</p>
<p>Format of XML for example purposes:
File1.xml</p>
<pre><code><?xml version="1.0" encoding="iso-8859-1" standalone="yes" ?>
<installation version="1.0">
<packs>
<pack name="Transaction Service" id="Transaction Service" required="no" >
<xinclude href="example/File2.xml" />
</pack>
</packs>
</code></pre>
<p>File2.xml</p>
<pre><code><xfragment>
<file src="..." />
</xfragment>
</code></pre>
<p>File2 does not need the standard XML header. The xml file is parsed at build time, because the resources it specifies are included in the installer. What isn't included is the actual XML information (order to write the files, where to put them etc.)</p>
<p>What I am looking to have produced:</p>
<pre><code><?xml version="1.0" encoding="iso-8859-1" standalone="yes" ?>
<installation version="1.0">
<packs>
<pack name="Transaction Service" id="Transaction Service" required="no" >
<file src="..." />
</pack>
</packs>
</code></pre>
<p>Thanks, I am going to start whipping it together in Java now, but hopefully someone has a simple answer. </p>
<p>Tim Reynolds</p>

<p>I have to write an applet that brings up a password dialog. The problem is that dialog is set to be always on top but when user clicks on IE window dialog gets hidden behind IE window nevertheless. And since dialog is modal and holds <strong>all</strong> IE threads IE pane does not refresh and dialog window is still painted on top of IE (but not refreshed). This behaviour confuses users (they <em>see</em> dialog on top of IE but it looks like it has hanged since it is not refreshe). </p>
<p>So I need a way to keep that dialog on top of everything. But any other solution to this problem would be nice. </p>
<p>Here's the code:</p>
<pre><code> PassDialog dialog = new PassDialog(parent);
/* do some non gui related initialization */
dialog.pack();
dialog.setLocationRelativeTo(null);
dialog.setAlwaysOnTop(true);
dialog.setVisible(true);
</code></pre>
<p>Resolution: As @shemnon noted I should make a window instead of (null, Frame, Applet) parent of modal dialog. So good way to initlialize parent was: </p>
<pre><code>parent = javax.swing.SwingUtilities.getWindowAncestor(theApplet);
</code></pre>

<p>This is from an example accompanying the agsXMPP .Net assembly. I've read up on delegates, but am not sure how that fits in with this line of code (which waits for the logon to occur, and then sends a message. I guess what I'm looking for is an understanding of why <code>delegate(0)</code> accomplishes this, in the kind of simple terms I can understand.</p>
<pre><code>xmpp.OnLogin += delegate(object o) {
xmpp.Send(new Message(new Jid(JID_RECEIVER),
MessageType.chat,
"Hello, how are you?"));
};
</code></pre>

<p>I try to use the Forms-Based authentication within an embedded Jetty 6.1.7 project.</p>
<p>That's why I need to serve servlets and html (login.html) under the same context
to make authentication work. I don't want to secure the hole application since
different context should need different roles. The jetty javadoc states that a
ContextHandlerCollection can handle different handlers for one context but I don't
get it to work. My sample ignoring the authentication stuff will not work, why?</p>
<pre><code>ContextHandlerCollection contexts = new ContextHandlerCollection();
// serve html
Context ctxADocs= new Context(contexts,"/ctxA",Context.SESSIONS);
ctxADocs.setResourceBase("d:\\tmp\\ctxA");
ServletHolder ctxADocHolder= new ServletHolder();
ctxADocHolder.setInitParameter("dirAllowed", "false");
ctxADocHolder.setServlet(new DefaultServlet());
ctxADocs.addServlet(ctxADocHolder, "/");
// serve a sample servlet
Context ctxA = new Context(contexts,"/ctxA",Context.SESSIONS);
ctxA.addServlet(new ServletHolder(new SessionDump()), "/sda");
ctxA.addServlet(new ServletHolder(new DefaultServlet()), "/");
contexts.setHandlers(new Handler[]{ctxA, ctxADocs});
// end of snippet
</code></pre>
<p>Any helpful thought is welcome!</p>
<p>Thanks.</p>

<p>I'd really like to handle this without monkey-patching but I haven't been able to find another option yet.</p>
<p>I have an array (in Ruby) that I need to sort by multiple conditions. I know how to use the sort method and I've used the trick on sorting using an array of options to sort by multiple conditions. However, in this case I need the first condition to sort ascending and the second to sort descending. For example:</p>
<pre><code>ordered_list = [[1, 2], [1, 1], [2, 1]]
</code></pre>
<p>Any suggestions?</p>
<p>Edit: Just realized I should mention that I can't easily compare the first and second values (I'm actually working with object attributes here). So for a simple example it's more like:</p>
<pre><code>ordered_list = [[1, "b"], [1, "a"], [2, "a"]]
</code></pre>

<p>This is a 3 part question regarding embedded RegEx into SQL statements. </p>
<ol>
<li><p>How do you embed a RegEx expression into an Oracle PL/SQL
select statement that will parse out
the “DELINQUENT” string in the text
string shown below?</p></li>
<li><p>What is the performance impact if used within a
mission critical business
transaction?</p></li>
<li><p>Since embedding regex
into SQL was introduced in Oracle
10g and SQL Server 2005, is it
considered a recommended practice?</p></li>

<p>In my web application there is a process that queries data from all over the web, filters it, and saves it to the database. As you can imagine this process takes some time. My current solution is to increase the page timeout and give an AJAX progress bar to the user while it loads. This is a problem for two reasons - 1) it still takes to long and the user must wait 2) it sometimes still times out.</p>
<p>I've dabbled in threading the process and have read I should async post it to a web service ("Fire and forget").</p>
<p>Some references I've read:<br>
- <a href="http://msdn.microsoft.com/en-us/library/ms978607.aspx#diforwc-ap02_plag_howtomultithread" rel="nofollow noreferrer">MSDN</a><br>
- <a href="http://aspalliance.com/329" rel="nofollow noreferrer">Fire and Forget</a></p>
<p>So my question is - what is the best method?</p>
<p>UPDATE: After the user inputs their data I would like to redirect them to the results page that incrementally updates as the process is running in the background.</p>

<p>I'm not talking about how to indent here. I'm looking for suggestions about the best way of organizing the chunks of code in a source file.</p>
<p>Do you arrange methods alphabetically? In the order you wrote them? Thematically? In some kind of 'didactic' order?</p>
<p>What organizing principles do you follow? Why?</p>

<p>I need to run a stored procedure from a C# application.</p>
<p>I use the following code to do so:</p>
<pre><code>Process sqlcmdCall = new Process();
sqlcmdCall.StartInfo.FileName = "sqlcmd.exe";
sqlcmdCall.StartInfo.Arguments = "-S localhost\\SQLEXPRESS -d some_db -Q \":EXIT(sp_test)\""
sqlcmdCall.Start();
sqlcmdCall.WaitForExit();
</code></pre>
<p>From the sqlcmdCall object after the call completes, I currently get an ExitCode of -100 for success and of 1 for failure (i.e. missing parameter, stored proc does not exist, etc...).</p>
<p>How can I customize these return codes?</p>
<p>H.</p>

<p>In Visual Studio 2005-2015 it is possible to find all lines containing certain references and display them in a "Find Results" window.</p>
<p>Now that these result lines are displayed, is there any keyboard shortcut that would allow adding debug breakpoints to all of them?</p>

<p>I'm convinced from <a href="http://www.masukomi.org/talks/unit_testing_talk_2/index.xul?data=slide_data.txt#page2" rel="nofollow noreferrer">this presentation</a> and other commentary here on the site that I need to learn to Unit Test. I also realize that there have been many questions about what unit testing is here. Each time I go to consider how it should be done in the application I am currently working on, I walk away confused. It is a xulrunner application application, and a lot of the logic is event-based - when a user clicks here, this action takes place.</p>
<p>Often the examples I see for testing are testing classes - they instantiate an object, give it mock data, then check the properties of the object afterward. That makes sense to me - but what about the non-object-oriented pieces?</p>
<p><a href="https://stackoverflow.com/questions/2364/what-is-your-experience-with-unit-testing-in-practice#2390">This guy mentioned</a> that GUI-based unit testing is difficult in most any testing framework, maybe that's the problem. The presentation linked above mentions that each test should only touch one class, one method at a time. That seems to rule out what I'm trying to do.</p>
<p>So the question - how does one unit testing procedural or event-based code? Provide a link to good documentation, or explain it yourself.</p>
<p>On a side note, I also have a challenge of not having found a testing framework that is set up to test xulrunner apps - it seems that the tools just aren't developed yet. I imagine this is more peripheral than my understanding the concepts, writing testable code, applying unit testing.</p>

<p>I'm working with a fairly simple database, from a Java application. We're trying to insert about 200k of text at a time, using the standard JDBC mysql adapter. We intermittently get a <code>com.mysql.jdbc.MysqlDataTruncation: Data truncation: Data too long for column error.</code></p>
<p>The column type is <code>longtext</code>, and database collation is <code>UTF-8</code>. The error shows up using both <code>MyISAM</code> and <code>InnoDB</code> table engines. Max packet size has been set ot 1 GB on both client and server sides, so that shouldn't be causing a problem, either.</p>

<p>For a System.Windows.Forms.TextBox with Multiline=True, I'd like to only show the scrollbars when the text doesn't fit.</p>
<p>This is a readonly textbox used only for display. It's a TextBox so that users can copy the text out. Is there anything built-in to support auto show of scrollbars? If not, should I be using a different control? Or do I need to hook TextChanged and manually check for overflow (if so, how to tell if the text fits?)</p>
<hr/>
<p>Not having any luck with various combinations of WordWrap and Scrollbars settings. I'd like to have no scrollbars initially and have each appear dynamically only if the text doesn't fit in the given direction.</p>
<hr/>
<p>@nobugz, thanks, that works when WordWrap is disabled. I'd prefer not to disable wordwrap, but it's the lesser of two evils.</p>
<hr/>
<p>@André Neves, good point, and I would go that way if it was user-editable. I agree that consistency is the cardinal rule for UI intuitiveness.</p>

<p>I wanted to "emulate" a popular flash game, Chrontron, in C++ and needed some help getting started. (NOTE: Not for release, just practicing for myself)</p>
<pre>
Basics:
Player has a time machine. On each iteration of using the time machine, a parallel state
is created, co-existing with a previous state. One of the states must complete all the
objectives of the level before ending the stage. In addition, all the stages must be able
to end the stage normally, without causing a state paradox (wherein they should have
been able to finish the stage normally but, due to the interactions of another state,
were not).
</pre>
<p>So, that sort of explains how the game works. You should play it a bit to really
understand what my problem is. <br /></p>
<p>I'm thinking a good way to solve this would be to use linked lists to store each state,
which will probably either be a hash map, based on time, or a linked list that iterates
based on time. I'm still unsure.<br /></p>
<p>ACTUAL QUESTION:</p>
<p>Now that I have some rough specs, I need some help deciding on which data structures to use for this, and why. Also, I want to know what Graphics API/Layer I should use to do this: SDL, OpenGL, or DirectX (my current choice is SDL). And how would I go about implementing parallel states? With parallel threads?</p>
<p>EDIT (To clarify more):<br />
OS -- Windows (since this is a hobby project, may do this in Linux later)<br />
Graphics -- 2D
Language -- C++ (must be C++ -- this is practice for a course next semester)</p>
<p>Q-Unanswered: SDL : OpenGL : Direct X <br />
Q-Answered: Avoid Parallel Processing <br />
Q-Answered: Use STL to implement time-step actions.<br /></p>
<pre>
So far from what people have said, I should:
1. Use STL to store actions.
2. Iterate through actions based on time-step.
3. Forget parallel processing -- period. (But I'd still like some pointers as to how it
could be used and in what cases it should be used, since this is for practice).
</pre>
<p>Appending to the question, I've mostly used C#, PHP, and Java before so I wouldn't describe myself as a hotshot programmer. What C++ specific knowledge would help make this project easier for me? (ie. Vectors?)</p>

<p>Is it possible to use .htaccess to process all six digit URLs by sending them to a script, but handle every other invalid URL as an error 404?</p>
<p>For example:</p>
<pre><code>http://mywebsite.com/132483
</code></pre>
<p>would be sent to:</p>
<pre><code>http://mywebsite.com/scriptname.php?no=132483
</code></pre>
<p>but</p>
<pre><code>http://mywebsite.com/132483a or
http://mywebsite.com/asdf
</code></pre>
<p>would be handled as a 404 error.</p>
<p>I presently have this working via a custom PHP 404 script but it's kind of kludgy. Seems to me that .htaccess might be a more elegant solution, but I haven't been able to figure out if it's even possible.</p>

<p>I have been working on some legacy C++ code that uses variable length structures (TAPI), where the structure size will depend on variable length strings. The structures are allocated by casting array <code>new</code> thus:</p>
<pre class="lang-cpp prettyprint-override"><code>STRUCT* pStruct = (STRUCT*)new BYTE[sizeof(STRUCT) + nPaddingSize];
</code></pre>
<p>Later on however the memory is freed using a <code>delete</code> call:</p>
<pre class="lang-cpp prettyprint-override"><code>delete pStruct;
</code></pre>
<p>Will this mix of array <code>new[]</code> and non-array <code>delete</code> cause a memory leak or would it depend on the compiler? Would I be better off changing this code to use <code>malloc</code> and <code>free</code> instead?</p>

<p>I am trying to scrape an html table and save its data in a database. What strategies/solutions have you found to be helpful in approaching this program.</p>
<p>I'm most comfortable with Java and PHP but really a solution in any language would be helpful.</p>
<p>EDIT: For more detail, the UTA (Salt Lake's Bus system) provides bus schedules on its website. Each schedule appears in a table that has stations in the header and times of departure in the rows. I would like to go through the schedules and save the information in the table in a form that I can then query. </p>
<p>Here's the <a href="http://www.rideuta.com/ridingUTA/schedules/routeSchedules.aspx" rel="nofollow noreferrer">starting point</a> for the schedules </p>

<p>Many of the parameters for interacting with the Office Object model in VSTO require object parameters that are passed by reference, even when the notional type of the parameter is an int or string.</p>
<ol>
<li>I suppose that this mechanism is used so that code can modify the parameter, although I can't figure out why these need to be passed as generic object instead of as their more appropriate types. Can anyone enlighten me?</li>
<li><p>The mechanism I've been using (cribbed from help and MSDN resources) essentially creates a generic object that contains the appropriate data and then passes that to the method, for example:</p>
<p>object nextBookmarkName = "NextContent";
object nextBookmark = this.Bookmarks.get_Item( ref nextBookmarkName ).Range;</p>
<p>Microsoft.Office.Interop.Word.Range newRng = this.Range( ref nextBookmark, ref nextBookmark );</p></li>
</ol>
<p>This seems like a lot of extra code, but I can't see a better way to do it. I'm sure I'm missing something; what is it? Or is this really the best practice?</p>

<p>I am trying to implement a request to an unreliable server. The request is a nice to have, but not 100% required for my perl script to successfully complete. The problem is that the server will occasionally deadlock (we're trying to figure out why) and the request will never succeed. Since the server thinks it is live, it keeps the socket connection open thus LWP::UserAgent's timeout value does us no good what-so-ever. What is the best way to enforce an absolute timeout on a request? </p>
<p>FYI, this is not an DNS problem. The deadlock has something to do with a massive number of updates hitting our Postgres database at the same time. For testing purposes, we've essentially put a while(1) {} line in the servers response handler. </p>
<p>Currently, the code looks like so:</p>
<pre><code>my $ua = LWP::UserAgent->new;
ua->timeout(5); $ua->cookie_jar({});
my $req = HTTP::Request->new(POST => "http://$host:$port/auth/login");
$req->content_type('application/x-www-form-urlencoded');
$req->content("login[user]=$username&login[password]=$password");
# This line never returns
$res = $ua->request($req);
</code></pre>
<p>I've tried using signals to trigger a timeout, but that does not seem to work. </p>
<pre><code>eval {
local $SIG{ALRM} = sub { die "alarm\n" };
alarm(1);
$res = $ua->request($req);
alarm(0);
};
# This never runs
print "here\n";
</code></pre>
<p>The final answer I'm going to use was proposed by someone offline, but I'll mention it here. For some reason, SigAction works while $SIG(ALRM) does not. Still not sure why, but this has been tested to work. Here are two working versions:</p>
<pre><code># Takes a LWP::UserAgent, and a HTTP::Request, returns a HTTP::Request
sub ua_request_with_timeout {
my $ua = $_[0];
my $req = $_[1];
# Get whatever timeout is set for LWP and use that to
# enforce a maximum timeout per request in case of server
# deadlock. (This has happened.)
use Sys::SigAction qw( timeout_call );
our $res = undef;
if( timeout_call( 5, sub {$res = $ua->request($req);}) ) {
return HTTP::Response->new( 408 ); #408 is the HTTP timeout
} else {
return $res;
}
}
sub ua_request_with_timeout2 {
print "ua_request_with_timeout\n";
my $ua = $_[0];
my $req = $_[1];
# Get whatever timeout is set for LWP and use that to
# enforce a maximum timeout per request in case of server
# deadlock. (This has happened.)
my $timeout_for_client = $ua->timeout() - 2;
our $socket_has_timedout = 0;
use POSIX;
sigaction SIGALRM, new POSIX::SigAction(
sub {
$socket_has_timedout = 1;
die "alarm timeout";
}
) or die "Error setting SIGALRM handler: $!\n";
my $res = undef;
eval {
alarm ($timeout_for_client);
$res = $ua->request($req);
alarm(0);
};
if ( $socket_has_timedout ) {
return HTTP::Response->new( 408 ); #408 is the HTTP timeout
} else {
return $res;
}
}
</code></pre>

<p>How do I set the column which has the header sort glyph, and its direction, in a .NET 2.0 WinForms ListView?</p>
<h2>Bump</h2>
<p>The listview is .net is not a managed control, it is a very thin wrapper around the Win32 ListView common control. It's not even a very good wrapper - it doesn't expose all the features of the real listview.</p>
<p>The Win32 listview common control supports drawing itself with themes. One of the themed elements is the header sort arrow. Windows Explorer's listview common control knows how to draw one of its columns with that theme element.</p>
<ul>
<li>does the Win32 listview support specifying which column has what sort order? </li>
<li>does the Win32 header control that the listview internally uses support specifying which column has what sort order? </li>
<li>does the win32 header control support custom drawing, so I can draw the header sort glyph myself?</li>
<li>does the win32 listview control support custom header drawing, so I can draw the header sort glyph myself?</li>

<p>What tools/websites do you use to read JavaDocs? </p>
<p>I currently use Firefox with 20+ tabs open when working on a J2EE project to have all the documentation available which is not very usable, is eating too much memory and is not searchable.</p>
<p>What I would expect from such a tool/website:</p>
<ul>
<li>Aggregate JavaDocs from different locations</li>
<li>Direct access to types like Ctrl+T in Eclipse or similar</li>
<li>Fulltext search</li>
<li>Cross referencing between all the Java libraries I've chosen</li>
<li>For a tool: offline support</li>
<li>Speed</li>
</ul>
<p>not mandatory: </p>
<ul>
<li>possibility to annotate things</li>
<li>support for different versions of a library (+ diffing ?)</li>
<li>IDE integration</li>
</ul>
<p>Edit:</p>
<p>Thanks for your answers. I knew most of the sites but gave them another try. Here is my judgement:</p>
<ul>
<li>built-in Eclipse/IDE features
<ul>
<li>tightly integrated</li>
<li>offline/online support</li>
</ul></li>
<li><a href="http://www.javadoconline.com" rel="noreferrer"><strike>javadoconline.com</strike></a> (no longer maintained)
<ul>
<li>works</li>
<li>clean looks</li>
<li>finds matches in more than one version of the api and allows easy switching</li>
<li>simple but working</li>
<li>fast</li>
</ul></li>
<li><a href="http://www.jdocs.com/" rel="noreferrer"><strike>jdocs</strike></a> (offline)
<ul>
<li>seems very sophisticated</li>
<li>sometimes slow</li>
<li>some recent versions of libraries seem to be missing (Seam 2.0.0, Hibernate Validators) but it looks like you can add them yourself</li>
<li>IDE integration (not tested)</li>
<li>wiki style comments to each item</li>
</ul></li>
<li><a href="http://www.docjar.com/" rel="noreferrer">docjar.com</a>
<ul>
<li>works</li>
<li>fast</li>
<li>cluttered UI</li>
</ul></li>
<li><a href="http://www.teria.com/~koseki/tools/gm/javadoc_isearch/" rel="noreferrer">javadoc_isearch</a>
<ul>
<li>greasemonkey script for firefox which makes navigating javadocs easier</li>
<li>works smooth and perfectly</li>
</ul></li>
</ul>

<p>I have a weird problem with a dropdownbox selectedIndex always being set to 0 upon postback. I'm not accidentally rebinding it in my code. In fact I've placed a breakpoint at the very first line of the page_load event and the value is already set to zero. The dropdown is in the master page of my project, I don't know if that makes a difference. I'm not referencing the control in my content holder. </p>
<p>If I set my autoPostBack = 'true' the page works fine. I don't have to change any code and the selectedIndex is maintained. I have also tried setting enableViewState on and off and it doesn't make a difference. At this point I'm grasping at straws to figure out what's going on. I've never had this problem before.</p>
<p>Here is the code in my page_load event.</p>
<pre><code> If CartEstablished Then
txtCustNum.Visible = False
btnCustSearch.Visible = False
lblCustNum.Visible = True
ddlSalesType.Visible = False
lblSalesType.Visible = True
ddlTerms.Visible = False
lblTerms.Visible = True
lblTerms.Text = TermsDescription
Else
txtCustNum.Visible = True
btnCustSearch.Visible = True
lblCustNum.Visible = False
lblSalesType.Visible = False
ddlSalesType.Visible = True
lblTerms.Visible = False
ddlTerms.Visible = True
End If
If Page.IsPostBack Then
GetUIValues()
Else
LoadTermCodes()
End If
</code></pre>
<p>The LoadTermCodes is where I bind the dropdownlist that is causing me problems.</p>

<p>I've got a custom handler applied to a class (using the Policy Injection Application Block in entlib 4) and I would like to know whether the input method is a property when Invoke is called. Following is what my handler looks like.</p>
<pre><code>[ConfigurationElementType(typeof(MyCustomHandlerData))]
public class MyCustomHandler : ICallHandler
{
public IMethodReturn Invoke(IMethodInvocation input, GetNextHandlerDelegate getNext)
{
if (input.MethodBase.IsPublic && (input.MethodBase.Name.Contains("get_") || input.MethodBase.Name.Contains("set_")))
{
Console.WriteLine("MyCustomHandler Invoke called with input of {0}", input.MethodBase.Name);
}
return getNext().Invoke(input, getNext);
}
public int Order { get; set; }
}
</code></pre>
<p>As you can see from my code sample, the best way I've thought of so far is by parsing the method name. Isn't there a better way to do this?</p>

<p>I'm coding the shutdown of a multithreaded server.If everything goes as it should all the threads exit by their own, but there's a small chance that a thread gets stuck.In this case it would be convenient to have a non-blocking join so I could do.</p>
<p><strong>Is there a way of doing a non-blocking pthread_join?
Some sort of timed join would be good too.</strong></p>
<p>something like this:</p>
<pre>
foreach thread do
nb_pthread_join();
if still running
pthread_cancel();
</pre>
<p>I can think more cases where a a non-bloking join would be useful.</p>
<p>As it seems there is no such a function so I have already coded a workaround, but it's not as simple as I would like.</p>

<p>I have an editable DataGridView with SelectionMode set to FullRowSelect (so the whole row is highlighted when the user clicks on any cell). However I would like the cell that currently has focus to be highlighted with a different back color (so the user can clearly see what cell they are about to edit). How can I do this (I do not want to change the SelectionMode)?</p>

<p>I am having a frequent problems with my web hosting (its shared)</p>
<p>I am not able to delete or change permission for a particular directory. The response is,</p>
<pre><code>Cannot delete. Directory may not be empty
</code></pre>
<p>I checked the permissions and it looks OK. There are 100's of files in this folder which I don't want. </p>
<p>I contacted my support and they solved it saying it was permission issue. But it reappeared. Any suggestions?</p>
<p>The server is Linux.</p>

<p>We use SAX to parse XML because it does not require the entire XML document to be read into memory in order to parse a single value. I read many articles that insisted SAX can only be used to parse/decode XML and not create it. Is this true?</p>

<p>Basically I would like to find a way to ddo something like:</p>
<pre><code><asp:Label ID="lID" runat="server" AssociatedControlID="txtId" Text="<%# MyProperty %>"></asp:Label>
</code></pre>
<p>I know I could set it from code behind (writing lId.Text = MyProperty), but I'd prefer doing it in the markup and I just can't seem to find the solution.
(MyProperty is a string property)
cheers</p>

<p>I'm trying to use maven2 to build an axis2 project. My project is configured as a parent project with AAR, WAR, and EAR modules. When I run the parent project's package goal, the console shows a successful build and all of the files are created. However the AAR file generated by AAR project is not included in the generated WAR project. The AAR project is listed as a dependency of WAR project. When I explicitly run the WAR's package goal, the AAR file is then included in the WAR file.</p>
<p>Why would the parent's package goal not include the necessary dependency while running the child's package goal does?</p>
<p>I'm using the maven-war-plugin v2.1-alpha-2 in my war project.</p>

<p>When I'm initializing a dialog, I'd like to select one of the radio buttons on the form. I don't see a way to associate a Control variable using the Class Wizard, like you would typically do with CButtons, CComboBoxes, etc...</p>
<p>Further, it doesn't like a CRadioButton class even exists.</p>
<p>How can I select one of the several radio buttons?</p>

<p>I am getting some errors thrown in my code when I open a Windows Forms form in Visual Studio's designer. I would like to branch in my code and perform a different initialization if the form is being opened by designer than if it is being run for real. </p>
<p>How can I determine at run-time if the code is being executed as part of designer opening the form?</p>

<p>Linux/Gcc/LD - Toolchain.</p>
<p>I would like to remove STL/Boost debug symbols from libraries and executable, for two reasons:</p>
<ol>
<li>Linking gets very slow for big programs</li>
<li>Debugging jumps into stl/boost code, which is annoying</li>
</ol>
<p>For 1. incremental linking would be a big improvement, but AFAIK ld does not support incremental linking. There is a workaround "pseudo incremental linking" in an 1999 dr.dobb's journal (not in the web any more, but at <a href="http://web.archive.org/web/20000131063231/www.ddj.com/articles/1999/9910/9910d/9910d.htm" rel="nofollow noreferrer">archive.org</a> (the idea is to put everything in a dynamic library and all updated object files in an second one that is loaded first) but this is not really a general solution.</p>
<p>For 2. there is a script <a href="http://ubuntuforums.org/showthread.php?p=4368377" rel="nofollow noreferrer">here</a>, but a) it did not work for me (it did not remove symbols), b) it is very slow as it works at the end of the pipe, while it would be more efficient to remove the symbols earlier.</p>
<p>Obviously, the other debug symbols should stay in place.</p>

<p>I have a list of addresses from a Database for which I'd like to put markers on a Yahoo Map. The <a href="http://developer.yahoo.com/maps/ajax/V3.8/index.html#YMap" rel="nofollow noreferrer"><code>addMarker()</code> method</a> on YMap takes a YGeoPoint, which requires a latitude and longitude. However, Yahoo Maps must know how to convert from addresses because <code>drawZoomAndCenter(LocationType,ZoomLevel)</code> can take an address. I could convert by using <code>drawZoomAndCenter()</code> then <code>getCenterLatLon()</code> but is there a better way, which doesn't require a draw?</p>
