<p>How to you find the URL that represents the documentation of a .NET framework method on the MSDN website?</p>
<p>For example, I want to embed the URL for the .NET framework method into some comments in some code. The normal "mangled" URL that one gets searching MSDN isn't very friendly looking: <a href="http://msdn.microsoft.com/library/xd12z8ts.aspx" rel="nofollow noreferrer">http://msdn.microsoft.com/library/xd12z8ts.aspx</a>. Using a Google search URL isn't all that pretty looking either.</p>
<p>What I really want a URL that can be embedded in comments that is plain and easy to read. For example,</p>
<p>// blah blah blah. See http://<....>/System.Byte.ToString for more information</p>

<p>This is a shared hosting environment. I control the server, but not necessarily the content. I've got a client with a Perl script that seems to run out of control every now and then and suck down 50% of the processor until the process is killed.</p>
<p>With ASP scripts, I'm able to restrict the amount of time the script can run, and IIS will simply shut it down after, say, 90 seconds. This doesn't work for Perl scripts, since it's running as a cgi process (and actually launches an external process to execute the script). </p>
<p>Similarly, techniques that look for excess resource consumption in a worker process will likely not see this, since the resource that's being consumed (the processor) is being chewed up by a child process rather than the WP itself.</p>
<p>Is there a way to make IIS abort a Perl script (or other cgi-type process) that's running too long? How??</p>

<p>I need to provide statistics on how many lines of code <code>(LOC)</code> associated with a system. The application part is easy but I need to also include any code residing within the SQL Server database. This would apply to stored procedures, functions, triggers, etc. </p>
<p>How can I easily get that info? Can it be done (accurately) with <strong>TSQL</strong> by querying the system <code>tables\sprocs</code>, etc?</p>

<p>Is it possible to create an instance of a generic type in Java? I'm thinking based on what I've seen that the answer is <code>no</code> (<em>due to type erasure</em>), but I'd be interested if anyone can see something I'm missing:</p>
<pre><code>class SomeContainer<E>
{
E createContents()
{
return what???
}
}
</code></pre>
<p>EDIT: It turns out that <a href="http://www.artima.com/weblogs/viewpost.jsp?thread=208860" rel="noreferrer">Super Type Tokens</a> could be used to resolve my issue, but it requires a lot of reflection-based code, as some of the answers below have indicated.</p>
<p>I'll leave this open for a little while to see if anyone comes up with anything dramatically different than Ian Robertson's <a href="http://www.artima.com/weblogs/viewpost.jsp?thread=208860" rel="noreferrer">Artima Article</a>.</p>

<p>If you have a statically allocated array, the Visual Studio debugger can easily display all of the array elements. However, if you have an array allocated dynamically and pointed to by a pointer, it will only display the first element of the array when you click the + to expand it. Is there an easy way to tell the debugger, show me this data as an array of type Foo and size X?</p>

<p>How can one detect being in a chroot jail without root privileges? Assume a standard BSD or Linux system. The best I came up with was to look at the inode value for "/" and to consider whether it is reasonably low, but I would like a more accurate method for detection.</p>
<p><code>[edit 20080916 142430 EST]</code> Simply looking around the filesystem isn't sufficient, as it's not difficult to duplicate things like /boot and /dev to fool the jailed user.</p>
<p><code>[edit 20080916 142950 EST]</code> For Linux systems, checking for unexpected values within /proc is reasonable, but what about systems that don't support /proc in the first place?</p>

<p>How can I detect when an Exception has been thrown anywhere in my application?</p>
<p>I'm try to auto-magically send myself an email whenever an exception is thrown anywhere in my Java Desktop Application. I figure this way I can be more proactive.</p>
<p>I know I could just explicitly log and notify myself whenever an exception occurs, but I'd have to do it everywhere and I might(more likely will) miss a couple.</p>
<p>Any suggestions?</p>

<p>How do you quickly find the URL for a Win32 API on MSDN? It's easy for .NET methods -- just add the method name (for example, System.Byte.ToString) to <a href="http://msdn.microsoft.com/library/" rel="nofollow noreferrer">http://msdn.microsoft.com/library/</a>.</p>
<p>However, for Win32 APIs (say GetLongPathName), this doesn't work: <a href="http://msdn.microsoft.com/en-us/library/GetLongPathName" rel="nofollow noreferrer">http://msdn.microsoft.com/en-us/library/GetLongPathName</a>.</p>
<p>I want to be able to use the URL in code comments or documentation. So the URL one gets with an MSDN or Google search (for example, <a href="http://msdn.microsoft.com/library/aa364980.aspx" rel="nofollow noreferrer">http://msdn.microsoft.com/library/aa364980.aspx</a>) isn't really what I'm looking for. I'd really like my code comments to look something like:</p>
<p>// blah blah blah. See <a href="http://msdn.microsoft.com/en-us/library/GetLongPathName" rel="nofollow noreferrer">http://msdn.microsoft.com/en-us/library/GetLongPathName</a> for more information.</p>
<p>What's the magic pixie dust for Win32 APIs? Or does it only work for .NET methods?</p>

<p>When you're doing a usual gdb session on an executable file on the same computer, you can give the run command and it will start the program over again.</p>
<p>When you're running gdb on an embedded system, as with the command <code>target localhost:3210</code>, how do you start the program over again without quitting and restarting your gdb session?</p>

There's a new CPAN.pm version (v1.9205) available!
[Current version is v1.7602]
You might want to try
install Bundle::CPAN
reload cpan
without quitting the current session. It should be a seamless upgrade
while we are running...

<p>Does anyone know of a good open source plugin for database querying and exploring within Eclipse? </p>
<p>The active Database Exploring plugin within Eclipse is really geared around being associated with a Java project. While I am just trying to run ad-hoc queries and explore the schema. I am effectively looking for a just a common, quick querying tool without the overhead of having to create a code project. I have found a couple open source database plugins for Eclipse but these have not seen active development in over a year.</p>
<p>Any suggestions?</p>

<p>I'm in an <strong>ASP.NET UserControl</strong>. When I type Control-K, Control-D to reformat all the markup, I get a series of messages from VS 2008:</p>
<p>"Could not reformat the document. The original format was restored."</p>
<p>"Could not complete the action."</p>
<p>"The operation could not be completed. The parameter is incorrect."</p>
<p>Anybody know what causes this?</p>
<p><strong>Edit</strong>: OK, that is just...weird.</p>
<p>The problem is here:</p>
<pre><code><asp:TableCell>
<asp:Button Text="Cancel" runat="server" ID="lnkCancel" CssClass="CellSingleItem" />
</asp:TableCell>
</code></pre>
<p>Somehow that asp:Button line is causing the problem. But if I delete any individual attribute, the formatting works. Or if I add a new attribute, the formatting works. Or if I change the tag to be non-self-closing, it works. But if I undo and leave it as-is, it doesn't work.</p>
<p>All I can figure is that this is some sort of really obscure, bizarre bug.</p>

<p>I'm handling the <code>onSelectIndexChanged</code> event. An event is raised when the DropDownList selection changes. the problem is that the DropDownList still returns the old values for <code>SelectedValue</code> and <code>SelectedIndex</code>. What am I doing wrong?</p>
<p>Here is the DropDownList definition from the aspx file:</p>
<pre><code><div style="margin: 0px; padding: 0px 1em 0px 0px;">
<span style="margin: 0px; padding: 0px; vertical-align: top;">Route:</span>
<asp:DropDownList id="Select1" runat="server" onselectedindexchanged="index_changed" AutoPostBack="true">
</asp:DropDownList>
<asp:Literal ID="Literal1" runat="server"></asp:Literal>
</div>
</code></pre>
<p>Here is the DropDownList <code>OnSelectedIndexChanged</code> event handler:</p>
<pre><code>protected void index_changed(object sender, EventArgs e)
{
decimal d = Convert.ToDecimal( Select1.SelectedValue );
Literal1.Text = d.ToString();
}
</code></pre>

<p>I have an ASP.Net/AJAX control kit project that i am working on. 80% of the time there is no problem. The page runs as it should. If you refresh the page it will sometimes show a javascript error "Sys is undefined".</p>
<p>It doesn't happen all the time, but it is reproducible. When it happens, the user has to shut down their browser and reopen the page.</p>
<p>This leads me to believe that it could be an IIS setting.</p>
<p>Another note. I looked at the page source both when I get the error, and when not. When the page throws errors the following code is missing:</p>
<pre><code><script src="/ScriptResource.axd?d=EAvfjPfYejDh0Z2Zq5zTR_TXqL0DgVcj_h1wz8cst6uXazNiprV1LnAGq3uL8N2vRbpXu46VsAMFGSgpfovx9_cO8tpy2so6Qm_0HXVGg_Y1&amp;t=baeb8cc" type="text/javascript"></script>
<script type="text/javascript">
//<![CDATA[
if (typeof(Sys) === 'undefined') throw new Error('ASP.NET Ajax client-side framework failed to load.');
//]]>
</script>
</code></pre>

<p>Can anyone recommend an efficient method to execute XSLT transforms of XML data within a Ruby application? The XSL gem (REXSL) is not available yet, and while I have seen a project or two that implement it, I'm wary of using them so early on. A friend had recommended a shell out call to Perl, but I'm worried about resources. </p>
<p>This is for a linux environment.</p>

<p>I've been asked to implement some code that will update a row in a MS SQL Server database and then use a stored proc to insert the update in a history table. We can't add a stored proc to do this since we don't control the database. I know in stored procs you can do the update and then call execute on another stored proc. Can I set it up to do this in code using one SQL command?</p>

<p>I have a column containing the strings 'Operator (1)' and so on until 'Operator (600)' so far.</p>
<p>I want to get them numerically ordered and I've come up with</p>
<pre><code>select colname from table order by
cast(replace(replace(colname,'Operator (',''),')','') as int)
</code></pre>
<p>which is very very ugly.</p>
<p>Better suggestions?</p>

<p>The problem is simple, but I'm struggling a bit already.</p>
<pre><code>Server server = new Server(8080);
Context context = new Context(server, "/", Context.NO_SESSIONS);
context.addServlet(MainPageView.class, "/");
context.addServlet(UserView.class, "/signup");
server.start();
</code></pre>
<p>That's a pretty standard piece of code that you can find anywhere in Jetty world. I have an application that embeds Jetty as a servlet engine and has some servlets. </p>
<p>Instantiation of some of these servlets requires heavy work on startup. Say – reading additional config files, connecting to the database, etc. How can I make the servlet engine instantiate all servlets eagerly, so that I can do all the hard work upfront and not on the first user request?</p>

<p>The Visual Studio compiler does not seem to warn on signed/unsigned assignments, only on comparisons. For example the code below will generate a warning on the if statement but not the initial assignments.</p>
<p>Is there anyway to make it catch these? I'm already at W4 but thought (hoped) there may be another setting somewhere.</p>
<p>Thanks,</p>
<pre><code>int foo(void)
{
unsigned int fooUnsigned = 0xffffffff;
int fooSigned = fooUnsigned; // no warning
if (fooSigned < fooUnsigned) // warning
{
return 0;
}
return fooSigned;
}
</code></pre>
<p>Update:</p>
<p>Quamrana is right, this is controlled by warning 4365 which appears to be off by default, even at W4. However you can explicitly enable it for a given warning level like so;</p>
<pre><code>#pragma warning (4 : 4365)
</code></pre>
<p>Which results in;</p>
<pre><code>warning C4365: 'initializing' : conversion from 'unsigned int' to 'int', signed/unsigned mismatch
</code></pre>

<p>Does anyone know of some good resources related to setting up heirarchical user account systems? I'm currently setting one up and am struggling with some of the more complex logic (especially with determining permissions). I was hoping I might be able to find some resources to help me along.</p>
<p><strong>Some Background:</strong>
I'm building a user account system for a web CMS that allows for a nested group hierarchy. Each group can be allowed/denied access to read, write, add, and delete (either explicitly for that group, or implicitly by one of its parents). As if that weren't complicated enough, the system also allows for users to be members of multiple groups. -- This is where I'm stuck. I've got everything set up, but I'm struggling with the actual logic for determining pemissions for a given user.</p>

<p>I am serving all content through apache with <code>Content-Encoding: zip</code> but that compresses on the fly. A good amount of my content is static files on the disk. I want to gzip the files beforehand rather than compressing them every time they are requested.</p>
<p>This is something that, I believe, <code>mod_gzip</code> did in Apache 1.x automatically, but just having the file with .gz next to it. That's no longer the case with <code>mod_deflate</code>.</p>

<p>I am pulling a long timestamp from a database, but want to present it as a Date using Tags only, no embedded java in the JSP.<br><br> I've created my own tag to do this because I was unable to get the parseDate and formatDate tags to work, but that's not to say they don't work.<br>
<br>
Any advice?</p>
<p>Thanks.</p>

<p>When creating a UserControl in WPF, I find it convenient to give it some arbitrary Height and Width values so that I can view my changes in the Visual Studio designer. When I run the control, however, I want the Height and Width to be undefined, so that the control will expand to fill whatever container I place it in. How can I acheive this same functionality without having to remove the Height and Width values before building my control? (Or without using DockPanel in the parent container.)</p>
<p>The following code demonstrates the problem:</p>
<pre><code><Window x:Class="ExampleApplication3.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:loc="clr-namespace:ExampleApplication3"
Title="Example" Height="600" Width="600">
<Grid Background="LightGray">
<loc:UserControl1 />
</Grid>
</Window>
</code></pre>
<p>The following definition of <code>UserControl1</code> displays reasonably at design time but displays as a fixed size at run time:</p>
<pre><code><UserControl x:Class="ExampleApplication3.UserControl1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Height="300" Width="300">
<Grid Background="LightCyan" />
</UserControl>
</code></pre>
<p>The following definition of <code>UserControl1</code> displays as a dot at design time but expands to fill the parent <code>Window1</code> at run time:</p>
<pre><code><UserControl x:Class="ExampleApplication3.UserControl1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<Grid Background="LightCyan" />
</UserControl>
</code></pre>

<p>I have around 1000 pdf filesand I need to convert them to 300 dpi tiff files. What is the best way to do this? If there is an SDK or something or a tool that can be scripted that would be ideal. </p>

<p>I have 28,000 images I need to convert into a movie.

<p>The files are named

webcam_2007-04-16_071404.jpg
Up to march 2008 or so.</p>
<p>Is there another way I can pass the filenames to mencoder so it doesn't stop part way?</p>

<p>I'm trying to have the same KDE Konsole experience within Mac OS X.</p>
<p>Here's my (overly complicated?) setup:</p>
<ul>
<li>I have Control and Command swapped at the System Preferences level. (Can't live without this)</li>
<li>Parallels lets you, at the Parallels application level, also reverse Control and Command. So I can undo the System Preferences setting (and get the setup I want within virtual Linux)</li>
</ul>
<p>I want this same per-application-opt-out for the Mac OS X Terminal app. Is it possible?</p>

<p>I'm working on a product feature that will allow the user to export data from a SQL CE database on one copy of my application and re-import it into SQL CE on the other end. This data is not whole tables, but the result of queries.</p>
<p>I had hoped to take advantage of .net's built-in XML-based serialization like in DataTable.WriteXML. But, none of the methods for executing queries against a SqlCeCommand provide an obvious way of serializing to XML or extracting a DataTable, which could provide the method.</p>
<p>Is there something I'm missing? Do I have to write my own serialization-deserialization methods or is there a built-in way.</p>

<p>The following question answers how to get large memory pages on Windows :<br>
"<a href="https://stackoverflow.com/questions/39059/how-do-i-run-my-app-with-large-pages-in-windows">how do i run my app with large pages in windows</a>".</p>
<p>The problem I'm trying to solve is how do I configure it on Vista and 2008 Server.</p>
<p>Normally you just allow a specific user to lock pages in memory and you are done. However on Vista and 2008 this only works if you are using an Administrator account. It doesn't help if the user is actually part of the Administrators group. All other users always get a 1300 error code stating that some rights are missing.</p>
<p>Anyone have a clue as to what else needs to be configured?</p>
<p>Thanks,
Staffan</p>

<p>I have a web report that uses a Django form (new forms) for fields that control the query used to generate the report (start date, end date, ...). The issue I'm having is that the page should work using the form's initial values (unbound), but I can't access the cleaned_data field unless I call <code>is_valid()</code>. But <code>is_valid()</code> always fails on unbound forms.</p>
<p>It seems like Django's forms were designed with the use case of editing data such that an unbound form isn't really useful for anything other than displaying HTML.</p>
<p>For example, if I have:</p>
<pre><code>if request.method == 'GET':
form = MyForm()
else:
form = MyForm(request.method.POST)
if form.is_valid():
do_query(form.cleaned_data['start_date'], form.cleaned_data['end_date'])
</code></pre>
<p>is_valid() will fail if this is a GET (since it's unbound), and if I do:</p>
<pre><code>if request.method == 'GET':
form = MyForm()
do_query(form.cleaned_data['start_date'], form.cleaned_data['end_date'])
else:
form = MyForm(request.method.POST)
if form.is_valid():
do_query(form.cleaned_data['start_date'], form.cleaned_data['end_date'])
</code></pre>
<p>the first call to do_query triggers exceptions on form.cleaned_data, which is not a valid field because <code>is_valid()</code> has not been called. It seems like I have to do something like:</p>
<pre><code>if request.method == 'GET':
form = MyForm()
do_query(form['start_date'].field.initial, form['end_date'].field.initial)
else:
form = MyForm(request.method.POST)
if form.is_valid():
do_query(form.cleaned_data['start_date'], form.cleaned_data['end_date'])
</code></pre>
<p>that is, there isn't a common interface for retrieving the form's values between a bound form and an unbound one.</p>
<p>Does anyone see a cleaner way to do this?</p>

<p>I have a JSP page that contains a scriplet where I instantiate an object. I would like to pass that object to the JSP tag without using any cache. </p>
<p>For example I would like to accomplish this: </p>
<pre><code><%@ taglib prefix="wf" uri="JspCustomTag" %>
<%
Object myObject = new Object();
%>
<wf:my-tag obj=myObject />
</code></pre>
<p>I'm trying to avoid directly interacting with any of the caches (page, session, servletcontext), I would rather have my tag handle that.</p>

<p>I'm working in a team environment where each developer works from their local desktop and deploys to a virtual machine that they own on the network. What I'm trying to do is set up the Visual Studio solution so that when they build the solution each projects deployment is handled in the post-build event to that developers virtual machine.</p>
<p>What I'd really like to do is give ownership of those scripts to the individual developer as well so that they own their post build steps and they don't have to be the same for everyone.</p>
<p>A couple of questions:</p>
<ul>
<li>Is a post build event the place to execute this type of deployment operation? If not what is the best place to do it?</li>
<li>What software, tools, or tutorials/blog posts are available to assist in developing an automatic deployment system that supports these scenarios?</li>
</ul>
<p><strong>Edit:</strong> MSBuild seems to be the way to go in this situation. Anyone use alternative technologies with any success?</p>
<p><strong>Edit:</strong> If you are reading this question and wondering how to execute a different set of MSBuild tasks for each developer please see this question; <a href="https://stackoverflow.com/questions/78018/executing-different-set-of-msbuild-tasks-for-each-user">Executing different set of MSBuild tasks for each user?</a></p>

<p>How do I dump the data, and only the data, not the schema, of some SQLite3 tables of a database (not all the tables)?
The dump should be in SQL format, as it should be easily re-entered into the database later and should be done from the command line. Something like</p>
<pre><code>sqlite3 db .dump
</code></pre>
<p>but without dumping the schema and selecting which tables to dump.</p>

<p>I have one applicationContext.xml file, and it has two org.springframework.orm.jpa.JpaTransactionManager (each with its own persistence unit, different databases) configured in a Spring middleware custom application.
<br><br>I want to use annotation based transactions (@Transactional), to not mess around with TransactionStatus commit, save, and rollback.<br><br>
A coworker mentioned that something gets confused doing this when there are multiple transaction managers, even though the context file is set configured correctly (the references go to the correct persistence unit.
Anyone ever see an issue?</p>
<hr>
<p>In your config, would you have two transaction managers?
Would you have txManager1 and txManager2?<br><br>
That's what I have with JPA, two different Spring beans that are transaction managers.</p>

<p>I see that within MySQL there are <code>Cast()</code> and <code>Convert()</code> functions to create integers from values, but is there any way to check to see if a value is an integer? Something like <code>is_int()</code> in PHP is what I am looking for.</p>

<p>I'm using membership and roles for authentication in my vb .net application. We have about 5 roles in the application with certain roles filling out a specific profile value. Example is the role is store and the profile value is store number. Obviously if you work for headquarters you don't have a store number so I don't care about it. Each store can also have more than 1 employee.</p>
<p>I need to get the users for a specific store number. Meaning I would only want the users that belong to store number 101 to show up that list. The way that we are doing this now is going through all the users and adding the users that fit the criteria into a sorted list. This functions but the problem is when you start passing about 3,000 users or so. It just becomes to slow to be any good. </p>
<p>How would you guys find a different way of doing it? I really don't want to do custom stored procedure or changing the underlying classes because I'm afraid of it all breaking on a later version of .net that they change membership and roles.</p>

<p>I'm trying to bind controls in a WPF form to an interface and I get a runtime error that it can't find the interface's properties.</p>
<p>Here's the class I'm using as a datasource:</p>
<pre><code>public interface IPerson
{
string UserId { get; set; }
string UserName { get; set; }
string Email { get; set; }
}
public class Person : EntityBase, IPerson
{
public virtual string UserId { get; set; }
public string UserName { get; set; }
public virtual string Email { get; set; }
}
</code></pre>
<p>Here's the XAML (an excerpt):</p>
<pre><code><TextBox Name="userIdTextBox" Text="{Binding UserId}" />
<TextBox Name="userNameTextBox" Text="{Binding UserName}" />
<TextBox Name="emailTextBox" Text="{Binding Email}" />
</code></pre>
<p>Here's the code behind (again, an excerpt):</p>
<pre><code>var person = PolicyInjection.Wrap<IPerson>(new Person());
person.UserId = "jdoe";
person.UserName = "John Doe";
person.Email = "[email protected]";
this.DataContext = person;
</code></pre>
<p>Note that the class I'm using as the data source needs to be an entity because I'm using Policy Injection through the entlib's Policy Injection Application Block.</p>
<p>I'm getting this error at runtime:</p>
<pre><code>System.Windows.Data Error: 16 : Cannot get 'Email' value (type 'String') from '' (type 'Person'). BindingExpression:Path=Email; DataItem='Person' (HashCode=22322349); target element is 'TextBox' (Name='emailTextBox'); target property is 'Text' (type 'String') TargetException:'System.Reflection.TargetException: Object does not match target type.

<p>In C#, if I want to deterministically clean up non-managed resources, I can use the "using" keyword. But for multiple dependent objects, this ends up nesting further and further:</p>
<pre><code>using (FileStream fs = new FileStream("c:\file.txt", FileMode.Open))
{
using (BufferedStream bs = new BufferedStream(fs))
{
using (StreamReader sr = new StreamReader(bs))
{
// use sr, and have everything cleaned up when done.
}
}
}
</code></pre>
<p>In C++, I'm used to being able to use destructors to do it like this:</p>
<pre><code>{
FileStream fs("c:\file.txt", FileMode.Open);
BufferedStream bs(fs);
StreamReader sr(bs);
// use sr, and have everything cleaned up when done.
}
</code></pre>
<p>Is there a better way in C# to do this? Or am I stuck with the multiple levels of nesting?</p>

<pre><code>EmployeeNumber =
string.IsNullOrEmpty(employeeNumberTextBox.Text)
? null
: Convert.ToInt32(employeeNumberTextBox.Text),
</code></pre>
<p>I often find myself wanting to do things like this (<code>EmployeeNumber</code> is a <code>Nullable<int></code> as it's a property on a LINQ-to-SQL dbml object where the column allows NULL values). Unfortunately, the compiler feels that</p>
<blockquote>
<p>There is no implicit conversion between 'null' and 'int'</p>
</blockquote>
<p>even though both types would be valid in an assignment operation to a nullable int on their own.</p>
<p>Using the null coalescing operator is not an option as far as I can see because of the inline conversion that needs to happen on the <code>.Text</code> string if it's not null.</p>
<p>As far as I know the only way to do this is to use an if statement and/or assign it in two steps. In this particular case I find that very frustrating because I wanted to use the object initializer syntax and this assignment would be in the initialization block...</p>
<p>Does anyone know a more elegant solution?</p>

<p>I'm building a quick csv from a mysql table with a query like:</p>
<pre><code>select DATE(date),count(date) from table group by DATE(date) order by date asc;
</code></pre>
<p>and just dumping them to a file in perl over a:</p>
<pre><code>while(my($date,$sum) = $sth->fetchrow) {
print CSV "$date,$sum\n"
}
</code></pre>
<p>There are date gaps in the data, though:</p>
<pre><code>| 2008-08-05 | 4 |
| 2008-08-07 | 23 |
</code></pre>
<p>I would like to pad the data to fill in the missing days with zero-count entries to end up with:</p>
<pre><code>| 2008-08-05 | 4 |
| 2008-08-06 | 0 |
| 2008-08-07 | 23 |
</code></pre>
<p>I slapped together a really awkward (and almost certainly buggy) workaround with an array of days-per-month and some math, but there has to be something more straightforward either on the mysql or perl side. </p>
<p>Any genius ideas/slaps in the face for why me am being so dumb?</p>
<hr>
<p>I ended up going with a stored procedure which generated a temp table for the date range in question for a couple of reasons:</p>
<ul>
<li>I know the date range I'll be looking for every time</li>
<li>The server in question unfortunately was not one that I can install perl modules on atm, and the state of it was decrepit enough that it didn't have anything remotely Date::-y installed</li>
</ul>
<p>The perl Date/DateTime-iterating answers were also very good, I wish I could select multiple answers!</p>

<p>What's the best way to implement the enum idiom in Ruby? I'm looking for something which I can use (almost) like the Java/C# enums.</p>

<p>I assumed that the C# margin property had a meaning like in CSS - the spacing around the outside of the control. But Margin values seem to be ignored to matter what values I enter.</p>
<p>Then I read on the SDK: </p>
<blockquote>
<p>Setting the Margin property on a
docked control has no effect on the
distance of the control from the the
edges of its container.</p>
</blockquote>
<p>Given that I'm placing controls on forms, and perhaps docking them, what does the Margin property get me?</p>

<p>Is there any complete guidance on doing AppBar docking (such as locking to the screen edge) in WPF? I understand there are InterOp calls that need to be made, but I'm looking for either a proof of concept based on a simple WPF form, or a componentized version that can be consumed.</p>

<p>(Eclipse 3.4, Ganymede)</p>
<p>I have an existing Dynamic Web Application project in Eclipse. When I created the project, I specified 'Default configuration for Apache Tomcat v6' under the 'Configuration' drop down.</p>
<p>It's a month or 2 down the line, and I would now like to change the configuration to Tomcat 'v5.5'. (This will be the version of Tomcat on the production server.)</p>
<p>I have tried the following steps (without success):</p>
<ul>
<li>I selected <code>Targeted Runtimes</code> under the Project <code>Properties</code><br>
The <code>Tomcat v5.5</code> option was disabled and The UI displayed this message:<br>
<code>If the runtime you want to select is not displayed or is disabled you may need to uninstall one or more of the currently installed project facets.</code> </li>
<li>I then clicked on the <code>Uninstall Facets...</code> link.<br>
Under the <code>Runtimes</code> tab, only <code>Tomcat 6</code> displayed.<br>
For <code>Dynamic Web Module</code>, I selected version <code>2.4</code> in place of <code>2.5</code>.<br>
Under the <code>Runtimes</code> tab, <code>Tomcat 5.5</code> now displayed.<br>
However, the UI now displayed this message:<br>
<code>Cannot change version of project facet Dynamic Web Module to 2.4.</code><br>
The <code>Finish</code> button was disabled - so I reached a dead-end.</li>
</ul>
<p>I CAN successfully create a NEW Project with a Tomcat v5.5 configuration. For some reason, though, it will not let me downgrade' an existing Project.</p>
<p>As a work-around, I created a new Project and copied the source files from the old Project. Nonetheless, the work-around was fairly painful and somewhat clumsy.</p>
<p>Can anyone explain how I can 'downgrade' the Project configuration from 'Tomcat 6' to 'Tomcat 5'? Or perhaps shed some light on why this happened?</p>
<p>Thanks<br>
Pete</p>

<p>I'm wondering if there's such a thing as Django-like ease of web app development combined with good deployment, debugging and other tools? </p>
<p>Django is a very productive framework for building content-heavy sites; the best I've tried and a breath of fresh air compared to some of the Java monstrosities out there. However it's written in Python which means there's little real support in the way of deployment/packaging, debugging, profilers and other tools that make building and maintaining applications much easier. </p>
<p>Ruby has similar issues and although I do like Ruby <strong>much</strong> better than I like Python, I get the impression that Rails is roughly in the same boat at Django when it comes to managing/supporting the app. </p>
<p>Has anyone here tried both Django and Grails (or other web frameworks) for non-trivial projects? How did they compare?</p>

<p>Given the case I made <strong>two independent changes</strong> in <em>one</em> file: eg. added a new method and changed another method.</p>
<p>I often don't want to commit both changes as <strong>one</strong> commit, but as <strong>two</strong> independent commits.</p>
<p>On a git repository I would use the <strong>Interactive Mode</strong> of <a href="http://linux.die.net/man/1/git-add" rel="noreferrer">git-add(1)</a> to split the <em>hunk</em> into smaller ones:</p>
<pre><code> git add --patch
</code></pre>
<p>What's the easiest way to do this with Subversion? (Maybe even using an Eclipse plug-in)</p>
<p><strong>Update:</strong><br/>
In <a href="http://tomayko.com/writings/the-thing-about-git" rel="noreferrer">The Thing About Git</a>, Ryan calls it: <em>“The Tangled Working Copy Problem.”</em></p>

<p>I'm having an issue with a query that currently uses </p>
<pre><code>LEFT JOIN weblog_data AS pwd
ON (pwd.field_id_41 != ''
AND pwd.field_id_41 LIKE CONCAT('%', ewd.field_id_32, '%'))
</code></pre>
<p>However I'm discovering that I need it to only use that if there is no exact match first. What's happening is that the query is double dipping due to the use of <code>LIKE</code>, so if it tests for an exact match first then it will avoid the double dipping issue. Can anyone provide me with any further guidance?</p>

<p>All the docs for SQLAlchemy give <code>INSERT</code> and <code>UPDATE</code> examples using the local table instance (e.g. <code>tablename.update()</code>... )</p>
<p>Doing this seems difficult with the declarative syntax, I need to reference <code>Base.metadata.tables["tablename"]</code> to get the table reference.</p>
<p>Am I supposed to do this another way? Is there a different syntax for <code>INSERT</code> and <code>UPDATE</code> recommended when using the declarative syntax? Should I just switch to the old way?</p>

<p>I need an algorithm that can determine whether two images are 'similar' and recognizes similar patterns of color, brightness, shape etc.. I might need some pointers as to what parameters the human brain uses to 'categorize' images. .. </p>
<p>I have looked at hausdorff based matching but that seems mainly for matching transformed objects and patterns of shape.</p>

<p>This may be a no-brainer for the WPF cognoscenti, but I'd like to know if there's a simple way to put text on the WPF ProgressBar. To me, an empty progress bar looks naked. That's screen real estate that could carry a message about <strong>what</strong> is in progress, or even just add numbers to the representation. Now, WPF is all about containers and extensions and I'm slowly wrapping my mind around that, but since I don't see a "Text" or "Content" property, I'm thinking I'm going to have to add something to the container that is my progress bar. Is there a technique or two out there that is more natural than my original WinForms impulses will be? What's the best, most WPF-natural way to add text to that progress bar?</p>

<p>I'm working on a web page where I'm making an AJAX call that returns a chunk of HTML like: </p>
<pre><code><div>
<!-- some html -->
<script type="text/javascript">
/** some javascript */
</script>
</div>
</code></pre>
<p>I'm inserting the whole thing into the DOM, but the JavaScript isn't being run. Is there a way to run it? </p>
<p>Some details: I can't control what's in the script block (so I can't change it to a function that could be called), I just need the whole block to be executed. I can't call eval on the response because the JavaScript is within a larger block of HTML. I could do some kind of regex to separate out the JavaScript and then call eval on it, but that's pretty yucky. Anyone know a better way?</p>

<p>I've always been told that adding an element to an array happens like this:</p>
<blockquote>
<p>An empty copy of the array+1element is
created and then the data from the
original array is copied into it then
the new data for the new element is
then loaded</p>
</blockquote>
<p>If this is true, then using an array within a scenario that requires a lot of element activity is contra-indicated due to memory and CPU utilization, correct?</p>
<p>If that is the case, shouldn't you try to avoid using an array as much as possible when you will be adding a lot of elements? Should you use iStringMap instead? If so, what happens if you need more than two dimensions AND need to add a lot of element additions. Do you just take the performance hit or is there something else that should be used?</p>

<p>I know that with mysql you can write SQL statements into a .sql file and run the file from the mysql command line like this:</p>
<pre><code>mysql> source script.sql
</code></pre>
<p>How do I pass a variable to the script? For example, if I want to run a script that retrieves all the employees in a department, I want to be able to pass in the number of the department as a variable.</p>
<p>I am not trying to run queries through a shell script. There are simple queries I run from the mysql command line. I'm tired of retyping them all the time, and writing a shell script for them would be overkill.</p>

<p>I am trying to solve numerically a set of partial differential equations in three dimensions. In each of the equations the next value of the unknown in a point depends on the current value of each unknown in the closest points.</p>
<p>To write an efficient code I need to keep the points close in the three dimensions close in the (one-dimensional) memory space, so that each value is called from memory just once.</p>
<p>I was thinking of using octtrees, but I was wondering if someone knows a better method.</p>

<p>We need to reliably get the Quick Launch folder for both All and Current users under both Vista and XP. I'm developing in C++, but this is probably more of a general Windows API question.</p>
<p>For reference, here is code to get the Application Data folder under both systems:</p>
<pre><code> HRESULT hres;
CString basePath;
hres = SHGetSpecialFolderPath(this->GetSafeHwnd(), basePath.GetBuffer(MAX_PATH), CSIDL_APPDATA, FALSE);
basePath.ReleaseBuffer();
</code></pre>
<p>I suspect this is just a matter of knowing which sub-folder Microsoft uses.</p>
<p>Under Windows XP, the app data subfolder is:</p>
<p>Microsoft\Internet Explorer\Quick Launch</p>
<p>Under Vista, it appears that the sub-folder has been changed to:</p>
<p>Roaming\Microsoft\Internet Explorer\Quick Launch</p>
<p>but I'd like to make sure that this is the correct way to determine the correct location.</p>
<p>Finding the <em>correct</em> way to determine this location is quite important, as relying on hard coded folder names almost always breaks as you move into international installs, etc... The fact that the folder is named 'Roaming' in Vista makes me wonder if there is some special handling related to that folder (akin to the Local Settings folder under XP).</p>
<p>EDIT:
The following msdn article: <a href="http://msdn.microsoft.com/en-us/library/bb762494.aspx" rel="nofollow noreferrer">http://msdn.microsoft.com/en-us/library/bb762494.aspx</a> indicates that CSIDL_APPDATA has an equivalent ID of FOLDERID_RoamingAppData, which does seem to support StocksR's assertion that CSIDL_APPDATA does return C:\Users\xxxx\AppData\Roaming, so it should be possible to use the same relative path for CSIDL_APPDATA to get to quick launch (\Microsoft\Internet Explorer\Quick Launch).</p>
<p>So the following algorithm is correct per MS:</p>
<pre><code>HRESULT hres;
CString basePath;
hres = SHGetSpecialFolderPath(this->GetSafeHwnd(), basePath.GetBuffer(MAX_PATH), CSIDL_APPDATA, FALSE);
basePath.ReleaseBuffer();
CString qlPath = basePath + "\\Microsoft\\Internet Explorer\\Quick Launch";
</code></pre>
<p>it would also be a good idea to check hres to ensure that the call to SHGetSpecialFolderPath was successful.</p>

<p>I'm trying to keep dependencies to a minimum for a program I contribute to, it's a small text editor.</p>
<p>GTK Textview doesn't seem to come with a built-in undo function. Is there any reference implementation I've been missing on so far? Is everyone writing their own undo function for their TextView widgets?</p>
<p>I'll be happy about any sample code - most happy about python sample code, as our project is in python.</p>

<p>I have 4 2D points in screen-space, and I need to reverse-project them back into 3D space. I know that each of the 4 points is a corner of a 3D-rotated rigid rectangle, and I know the size of the rectangle. How can I get 3D coordinates from this?</p>
<p>I am not using any particular API, and I do not have an existing projection matrix. I'm just looking for basic math to do this. Of course there isn't enough data to convert a single 2D point to 3D with no other reference, but I imagine that if you have 4 points, you know that they're all at right-angles to each other on the same plane, and you know the distance between them, you should be able to figure it out from there. Unfortunately I can't quite work out how though.</p>
<p>This might fall under the umbrella of photogrammetry, but google searches for that haven't led me to any helpful information. </p>

<p>I seldom use inheritance, but when I do, I never use protected attributes because I think it breaks the encapsulation of the inherited classes.</p>
<p>Do you use protected attributes ? what do you use them for ?</p>

<p>I am receiving a 3rd party feed of which I cannot be certain of the namespace so I am currently having to use the local-name() function in my XSLT to get the element values. However I need to get an attribute from one such element and I don't know how to do this when the namespaces are unknown (hence need for local-name() function).</p>
<p>N.B. I am using .net 2.0 to process the XSLT</p>

<p>I am working on a project where the requirement is to have a date calculated as being the last Friday of a given month. I think I have a solution that only uses standard Java, but I was wondering if anyone knew of anything more concise or efficient. Below is what I tested with for this year:</p>
<pre><code> for (int month = 0; month < 13; month++) {
GregorianCalendar d = new GregorianCalendar();
d.set(d.MONTH, month);
System.out.println("Last Week of Month in " + d.getDisplayName(d.MONTH, Calendar.LONG, Locale.ENGLISH) + ": " + d.getLeastMaximum(d.WEEK_OF_MONTH));
d.set(d.DAY_OF_WEEK, d.FRIDAY);
d.set(d.WEEK_OF_MONTH, d.getActualMaximum(d.WEEK_OF_MONTH));
while (d.get(d.MONTH) > month || d.get(d.MONTH) < month) {
d.add(d.WEEK_OF_MONTH, -1);
}
Date dt = d.getTime();
System.out.println("Last Friday of Last Week in " + d.getDisplayName(d.MONTH, Calendar.LONG, Locale.ENGLISH) + ": " + dt.toString());
}
</code></pre>

<p>I'm teaching a kid programming, and am introducing some basic artificial intelligence concepts at the moment. To begin with we're going to implement a tic-tac-toe game that searches the entire game tree and as such plays perfectly. Once we finish that I want to apply the same concepts to a game that has too many positions to evaluate every single one, so that we need to implement a heuristic to evaluate intermediate positions.</p>
<p>The best thing I could think of was <a href="http://en.wikipedia.org/wiki/Dots-and-boxes" rel="nofollow noreferrer">Dots and Boxes</a>. It has the advantage that I can set the board size arbitrarily large to stop him from searching the entire tree, and I can make a very basic scoring function be the number of my boxes minus the number of opponent boxes. Unfortunately this means that for most of the beginning of the game every position will be evaluated equivalently with a score of 0, because it takes quite a few moves before players actually start making boxes.</p>
<p>Does anyone have any better ideas for games? (Or a better scoring function for dots and boxes)?</p>

<p>I know how to do this in SQL for several DB platforms, but would like to know what database independent interfaces exist in <code>java.sql</code> to do this, and any input on people's experience with this across DB platforms.</p>

<p>In Microsoft IL, to call a method on a value type you need an indirect reference. Lets say we have an ILGenerator named "il" and that currently we have a Nullable on top of the stack, if we want to check whether it has a value then we could emit the following:</p>
<pre><code>var local = il.DeclareLocal(typeof(Nullable<int>));
il.Emit(OpCodes.Stloc, local);
il.Emit(OpCodes.Ldloca, local);
var method = typeof(Nullable<int>).GetMethod("get_HasValue");
il.EmitCall(OpCodes.Call, method, null);
</code></pre>
<p>However it would be nice to skip saving it as a local variable, and simply call the method on the address of the variable already on the stack, something like:</p>
<pre><code>il.Emit(/* not sure */);
var method = typeof(Nullable<int>).GetMethod("get_HasValue");
il.EmitCall(OpCodes.Call, method, null);
</code></pre>
<p>The ldind family of instructions looks promising (particularly ldind_ref) but I can't find sufficient documentation to know whether this would cause boxing of the value, which I suspect it might.</p>
<p>I've had a look at the C# compiler output, but it uses local variables to achieve this, which makes me believe the first way may be the only way. Anyone have any better ideas?</p>
<p>**** Edit: Additional Notes ****</p>
<p>Attempting to call the method directly, as in the following program with the lines commented out, doesn't work (the error will be "Operation could destabilise the runtime"). Uncomment the lines and you'll see that it does work as expected, returning "True".</p>
<pre><code>var m = new DynamicMethod("M", typeof(bool), Type.EmptyTypes);
var il = m.GetILGenerator();
var ctor = typeof(Nullable<int>).GetConstructor(new[] { typeof(int) });
il.Emit(OpCodes.Ldc_I4_6);
il.Emit(OpCodes.Newobj, ctor);
//var local = il.DeclareLocal(typeof(Nullable<int>));
//il.Emit(OpCodes.Stloc, local);
//il.Emit(OpCodes.Ldloca, local);
var getValue = typeof(Nullable<int>).GetMethod("get_HasValue");
il.Emit(OpCodes.Call, getValue);
il.Emit(OpCodes.Ret);
Console.WriteLine(m.Invoke(null, null));
</code></pre>
<p>So you can't simply call the method with the value on the stack because it's a value type (though you could if it was a reference type).</p>
<p>What I'd like to achieve (or to know whether it is possible) is to replace the three lines that are shown commented out, but keep the program working, without using a temporary local.</p>

<p>In my SWT Java app I often want to return information from inside a Display.syncExec() call. The best way I've found so far to do this is:</p>
<pre><code>final ArrayList<Integer> result = new ArrayList<Integer>();
GUI.display().syncExec(new Runnable(){ public void run() {
MessageBox mb = /* ... */;
/* set up messagebox */
result.add(mb.open());
}});
if (SWT.OK == result.get(0)) { /* ... */ }
</code></pre>
<p>I think this is allowed because ArrayList is thread-safe, but is there a better container I should be using, or an easier way altogether?</p>

<p>I really want to get the google Calendar Api up an running. I found a <a href="http://www.ibm.com/developerworks/library/x-googleclndr/" rel="nofollow noreferrer">great article</a> about how to get started. I downloaded the Zend GData classes. I have php 5 running on my dev box and all the exetensions should be loading.</p>
<p>I cant get openssl running and recieve the following error when I try to run any of the example page which should connect to my Google Calendar.</p>
<pre><code>Uncaught exception 'Zend_Gdata_App_HttpException' with message 'Unable to Connect to ssl://www.google.com:443. Error #24063472: Unable to find the socket transport "ssl" - did you forget to enable it when you configured PHP?'
</code></pre>
<p>I have looked in many places to try to get OpenSSL running on my machine and installed. </p>
<p>Does anyone know of a simple failsafe tutorial to get this combination up and running?</p>

<p>PHP5 has a "magic method" <code>__call()</code>that can be defined on any class that is invoked when an undefined method is called -- it is roughly equivalent to Ruby's <code>method_missing</code> or Perl's <code>AUTOLOAD</code>. Is it possible to do something like this in older versions of PHP?</p>

<p>Does anyone know a mechanism to calculate at compile-time the LCM (Least Common Multiple) and/or GCD (Greatest Common Denominator) of at least two number in <strong>C</strong> (<strong>not C++</strong>, I know that template magic is available there)?</p>
<p>I generally use <strong>GCC</strong> and recall that it can calculate certain values at compile-time when all inputs are known (ex: sin, cos, etc...).</p>
<p>I'm looking for how to do this in <strong>GCC</strong> (preferably in a manner that other compilers could handle) and hope the same mechanism would work in Visual Studio.</p>

<p>I just got surprised by something in TSQL. I thought that if xact_abort was on, calling something like</p>
<pre><code>raiserror('Something bad happened', 16, 1);
</code></pre>
<p>would stop execution of the stored procedure (or any batch).</p>
<p>But my ADO.NET error message just proved the opposite. I got both the raiserror error message in the exception message, plus the next thing that broke after that.</p>
<p>This is my workaround (which is my habit anyway), but it doesn't seem like it should be necessary:</p>
<pre><code>if @somethingBadHappened
begin;
raiserror('Something bad happened', 16, 1);
return;
end;
</code></pre>
<p>The docs say this:</p>
<blockquote>
<p>When SET XACT_ABORT is ON, if a Transact-SQL statement raises a run-time error, the entire transaction is terminated and rolled back.</p>
</blockquote>
<p>Does that mean I must be using an explicit transaction?</p>

I want to change some code around in the code behind file, but every time I stop at a break point and try to edit something I get the following error message: "Changes are not allowed when the debugger has been attached to an already running process or the code being debugged is optimized."</p>
<p>I'm pretty sure I have all the "Edit and Continue" options enabled. Any suggestions?</p>

<p>How can I create a regular expression that will grab delimited text from a string? For example, given a string like </p>
<pre><code>text ###token1### text text ###token2### text text
</code></pre>
<p>I want a regex that will pull out <code>###token1###</code>. Yes, I do want the delimiter as well. By adding another group, I can get both:</p>
<pre><code>(###(.+?)###)

<p>When developing WPF UserControls, what is the best way to expose a DependencyProperty of a child control as a DependencyProperty of the UserControl? The following example shows how I would currently expose the Text property of a TextBox inside a UserControl. Surely there is a better / simpler way to accomplish this?</p>
<pre class="lang-xml prettyprint-override"><code> <UserControl x:Class="WpfApplication3.UserControl1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<StackPanel Background="LightCyan">
<TextBox Margin="8" Text="{Binding Text, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type UserControl}}}" />
</StackPanel>
</UserControl>
</code></pre>
<pre class="lang-cs prettyprint-override"><code> using System;
using System.Windows;
using System.Windows.Controls;
namespace WpfApplication3
{
public partial class UserControl1 : UserControl
{
public static DependencyProperty TextProperty = DependencyProperty.Register("Text", typeof(string), typeof(UserControl1), new PropertyMetadata(null));
public string Text
{
get { return GetValue(TextProperty) as string; }
set { SetValue(TextProperty, value); }
}
public UserControl1() { InitializeComponent(); }
}
}

<p>XmlElement.Attributes.Remove* methods are working fine for arbitrary attributes resulting in the removed attributes being removed from XmlDocument.OuterXml property. Xmlns attribute however is different. Here is an example:</p>
<pre><code>XmlDocument doc = new XmlDocument();
doc.InnerXml = @"<Element1 attr1=""value1"" xmlns=""http://mynamespace.com/"" attr2=""value2""/>";
doc.DocumentElement.Attributes.RemoveNamedItem("attr2");
Console.WriteLine("xmlns attr before removal={0}", doc.DocumentElement.Attributes["xmlns"]);
doc.DocumentElement.Attributes.RemoveNamedItem("xmlns");
Console.WriteLine("xmlns attr after removal={0}", doc.DocumentElement.Attributes["xmlns"]);
</code></pre>
<p>The resulting output is</p>
<pre><code>xmlns attr before removal=System.Xml.XmlAttribute
xmlns attr after removal=
<Element1 attr1="value1" xmlns="http://mynamespace.com/" />
</code></pre>
<p>The attribute seems to be removed from the Attributes collection, but it is not removed from XmlDocument.OuterXml.
I guess it is because of the special meaning of this attribute.</p>
<p>The question is how to remove the xmlns attribute using .NET XML API.
Obviously I can just remove the attribute from a String representation of this, but I wonder if it is possible to do the same thing using the API.</p>
<p>@Edit: I'm talking about .NET 2.0.</p>
