373,731 | <p>An example of what I'm talking about:</p>
<pre><code>class Person < ActiveRecord::Base
def name=(name)
super(name.capitalize)
end
def name
super().downcase # not sure why you'd do this; this is just an example
end
end
</code></pre>
<p>This seems to work, but I was just read the section on overriding attribute methods in the <a href="http://rails.rubyonrails.com/classes/ActiveRecord/Base.html" rel="noreferrer">ActiveRecord::Base docs</a>, and it suggests using the <code>read_attribute</code> and <code>write_attribute</code> methods. I thought there must be something wrong with what I'm doing in the example above; otherwise, why would they bless these methods as the "right way" to override attribute methods? They're also forcing a much uglier idiom, so there must be a good reason...</p>
<p>My real question: Is there something wrong with this example?</p>

<p>Thanks to all who posted. As has been mentioned in the comments, this is a duplicate, but there are so many great answers here I want to preserve them for the community so I'm turning it into a community post. Here is the link to the other question:</p>

373,856 | <p>I'm hosting a custom editing control in a <code>DataGridView</code>, which for the record is a <code>TextBox</code> and <code>Button</code> together in a <code>UserControl</code>. I have inherited from <code>DataGridViewColumn</code> for the new column and <code>DataGridViewTextBoxCell</code> for the new cell.</p>
<p>With a normal <code>DataGridViewTextBoxCell</code>, if you press a key when the cell has focus, it will begin edit mode <b>and</b> the character you typed will appear in the <code>TextBoxEditingControl</code>. However, in my inherited cell, no value is being passed down on keypress. (In fact, you have to manually pass the current cell value in <code>InitializeEditingControl</code> or nothing will show up at all.) So, the first character you type (the one that begins edit mode) is lost.</p>
<p>I have tried <code>OnKeyPress</code>, <code>OnKeyDown</code>, and <code>OnKeyUp</code> in the <code>DataGridViewCell</code> but they never get called. <code>KeyEntersEditMode</code>, however, does seem to get called, and only when it is checking against a pressed key, so this might be a good place to start. The problem then becomes how to translate a KeyEventArgs to a <code>char</code>. This is trivial for alphabet and numbers, but since not all keyboards are created equal, handling other keys is messy and complicated at best. If there's a converter class that will do this automagically, please enlighten me.</p>
<p>Has anyone else encountered this problem or found a good workaround?</p>
<p>Note: This problem applies when <code>EditMode</code> is set to any variation of <code>EditOnKeystroke</code>. Setting to <code>EditOnEnter</code> is a valid workaround for my project, but I'd like to emulate the default behavior of the <code>TextBoxEditingControl</code> as well.</p>

373,888 | <p>When I use (in MS Access 2003 SP3): </p>
<pre><code>SELECT * INTO NewTable FROM SomeQuery;
</code></pre>
<p>MEMO fields are converted to TEXT fields (which are limited to 255 characters), so longer texts are cut.</p>
<p>The output of the query itself is fine and not truncated; the text is cut only in the new table that is created.</p>
<p>An update: I managed to focus the problem on the IIF statement in my query.
When I remove the IIF, the new table contains the MEMO field, but with the IIF the same field appears as TEXT. The weird thing is that the query output shows the long strings in full, even when the IIF is being used. Only when it is 'copied' to the new table (by the INTO statement), the text is cut.</p>
<p>Do you know of any problems that IIF may cause to MEMO fields?</p>

373,900 | <p>As usual, when my brain's messing with something I can't figure out myself, I come to you guys for help :)</p>
<p>This time I've been wondering why stdafx.h works the way it does? To my understanding it does 2 things:</p>
<ul>
<li>Includes standard headers which we
<em>might</em> (?) use and which are rarely changed</li>
<li>Work as a compiler-bookmark for when
code is no longer precompiled.</li>
</ul>
<p>Now, these 2 things seems like two very different tasks to me, and I wonder why they didn't do two seperate steps to take care of them? To me it seems reasonable to have a #pragma-command do the bookmarking stuff and to optionally have a header-file a long the lines of windows.h to do the including of often-used headers... Which brings me to my next point: Why are we forced to include often-used headers through stdafx.h? Personally, I'm not aware of any often used headers I use that I'm not already doing my own includes for - but maybe these headers are necessary for .dll generation?</p>
<p>Thx in advance</p>

373,968 | <p>I have a class that parses very large file (that can't fit in memory) and I'm currently utilizing the IEnumerable interface to use foreach so I can easily grab the parsed contents of the file line by line. Currently, I'm trying to write this to file using an XMLSerializer. It insists on enumerating the class and in my case, this means dumping large, parsed content of files to the XML. Is there anyway (hackish or elegant) to use this interface and still get the "expected" functionality out of a XMLSerializer? </p>
<p>(I only call this "expected" because this seems an expected outcome if I was implementing some collection interface rather than IEnumerable. Perhaps my concepts of IEnumerable and collections is all out of whack. :( )</p>

373,988 | <p>I'm curious How do you people think ? (I mean a way of thinking) about design architecture of your Libraries, Systems, Frameworks, etc. before start coding it.</p>
<p>I recently find my self feeling pain in what I've done, and practically every time I want to start everything from scratch..</p>
<p>I do design before, painting some schemes on the paper and imagine how it will work, but maybe I do it in a wrong way ?</p>
<p>For example how do you decide what Interfaces you will need, or how everything will be connected in a best way ? </p>
<p>(I had a problem some day ago, my friend asked me a library what I've done some time ago, and instead of giving him just one file, I had to give him about 3-4 files, and that's because they're connected in some way.. but not in the right one I think :) so it was my mistake in design..)</p>

374,007 | <p>Everything was going well. Nightly builds ran for more than a month with no problems. However, suddenly when invoking the feature builder from Eclipse the execution ends right away with the message.</p>
<p>ERRORLEVEL 13</p>
<p>As far as I know I haven't changed anything, as this computer is normally not touched. (It is only used for the nightly builds).</p>
<p>I've googled around to see what this error means but to no avail. <a href="http://www.ibm.com/developerworks/websphere/library/techarticles/0505_weisz/0505_weisz.html" rel="nofollow noreferrer">I found a link from IBM that shows a custom bat file that catches this error, but the explanation given is not very useful.</a></p>
<p>My guess is that this is related to the workspace, somehow, or that the whole eclipse installation is corrupted.</p>
<p>Do you have any idea what this error means and how can it be corrected?</p>

374,009 | <p>Setup is SQL2005 SP2 with Reporting Services installed local on Win2003 64bit.
When users browse report manager on <a href="http://server/reports" rel="nofollow noreferrer">http://server/reports</a> they get login dialog for every request, but only if they use IE7. In FireFox all works.</p>
<p>The site is in "local intranet" zone on IE.</p>

374,024 | <p>We have a web application project (not a web site), until the day we have added batch="false" to web.config web development server was compiling all the web application instead of the page that was requested.</p>
<pre><code><compilation debug="true" batch="false">
<assemblies>
...
</assemblies>
</compilation>
</code></pre>
<p>This make us faster. But I don't know what changed (I have inspected both foo.cproj and web.config from repository, comparing older versions but find nothing can cause this slowness).</p>
<p>I looked at %temp%/Temporary ASP.NET Files; after I compile my web app (not recompile, shift + f6), then I request a page and I see that web server deletes all of already compiled files from %temp%/Temporary ASP.NET Files and recreates. I don't know if this is normal but it seemed to me a full recompilation of all web app, which is very slow. (I looked via process explorer to wevdev.wevserver.exe it calls csc.exe several times)</p>
<p>How can I can make compilation faster? Thanks...</p>

374,043 | <p>We have a fairly large group of Maven2 projects, with a root POM file listing 10+ modules and a lot of properties used by the modules (dependency version numbers, plugin configuration, common dependencies, etc). Some of the modules are, like the root project, parents to other sets of modules. </p>
<p>To clarify, the root project and said parent projects are set to pom packaging (as opposed to e.g. jar).</p>
<p>Because there are many dependencies between the different projects, I like to use mvn eclipse:eclipse on the root project, which enables me to debug/step into any project at any time. </p>
<p>However, with this approach, the root POM itself, and all other pom-packaged projects, are unavailable in Eclipse. So, if I want to edit them, I have to open them some other way. This is becoming a bit of a hassle. </p>
<p>So, my question is: is it possible to somehow make pom-packaged projects available in Eclipse? If not, do you have any tips that could make my work with these projects easier? </p>
<p>For the record, I'm currently using MyEclipse 7.0.</p>

374,059 | <p>I am using http remoting in C# to talk between two applications.
Earlier when I was running both applications on a single machine/two machines, it was very slow.
We have a proxy server to connect to the internet. We set "Bypass proxy server for local addresses" in IE and now when I run both applications on one machine the communication is happening quite fast. (by a factor of 10 nearly)</p>
<p>But if I run each application on a different machine then it is still slow, like it was the case before setting the "Bypass proxy server..."</p>
<p>Any insight will be helpful.</p>

374,061 | <p>I build JQuery/JS/PHP/mySQL app with DB records management and need to provide reliable & complete feedback to the user on AJAX calls, modifying back end DB records. The problem IMHO is <code>$.ajax</code> <code>success:</code> and <code>error:</code> functions indicate just AJAX transport layer success and not the whole process. What if DB modification fail? How can one provide the complete feedback to the user?</p>
<p>I ended up with </p>
<pre>
$.ajax({
url: "/action/delete",
data: "rowid="+rowid,
complete: function(xmlHttp) {
if ( xmlHttp.responseText ) alert('Success - back end returned "success"');
else alert('failure - back end returned NULL')
}
});
</pre>
<p>and PHP response:</p>
<pre>
$success = deleteRecord( $_GET(rowid) );
if($success) {
print 'success';
} else {
print NULL;
}
exit();
</pre>
<p>The idea is simple - if I manage to get positive feedback from the back end, then the whole operation succeeded, if not - user don't care where problem occurred.</p>
<p>Thank you in advance, your feedback is highly appreciated.</p>

<p>ListView has a IsSynchronizedWithCurrentItem property, which rocks. e.g. If I had another ListView showing a list of nodes and both listViews have this property set to true. Changing selection of node in NodesListView will update the PropertiesListView automatically.</p>

<p>Is there a more 'the WPF way' kind of solution to this problem ? Or do I have to handle the NodeSelectionChanged event of the Tree and refresh the listView via code.</p>

<item name='GenMsgText'><text>The signature will be discarded.<break/>

if ($t =~m {\n}i)

374,135 | <p>We have several legacy applications which use Access databases for storing data and/or configuration. </p>
<p>Sometimes we have to do small changes or corrections at our customers databases. (Adding an index, modifying a data row, ...) In many cases Access is available on the customers' workstations, but sometimes it's not.</p>
<p>Is there any small tool for doing small maintenance operations on Access databases which needs not to be installed? (i.e. can be started from a USB stick)</p>
<p>I know of Squirrel SQL, but I'm hoping for something more lightweight.</p>

374,152 | <p>I am trying to format some bad html to output into a pop window. The html is stored in a field in a mysql database.</p>
<p>I have been performing json_encode and htmlspecialchars on the row in the php like so:</p>
<pre><code>$html = htmlentities(json_encode($row2['ARTICLE_DESC']));
</code></pre>
<p>and calling my makewindows function, which simply takes the html as a paramter and uses it withdocument.write like so:</p>
<pre><code> <p><a href='#' onclick=\"makewindows('".$html."'); return false;\">Click for full description </a></p>
</code></pre>
<p>This works ok, as in some html code is produced, such as the following:</p>
<p><a href="http://www.nomorepasting.com/getpaste.php?pasteid=22823&seen=true&wrap=on&langoverride=html4strict" rel="nofollow noreferrer">http://www.nomorepasting.com/getpaste.php?pasteid=22823&seen=true&wrap=on&langoverride=html4strict</a></p>
<p>pasted there because I do not know how to wrap lines in SO</p>
<p>The problem is that htmlspecialchars does not seem to be stripping bad html data, as no popup window is created. The error I receive with firebug is</p>
<p>missing ) after argument list</p>
<p>However the html is outside of my control.</p>
<p>From what I have read, I am taking the correct steps. If I am missing something out, what is it?</p>
<p>My full make windows function:</p>
<pre><code>function makewindows(html){
child1 = window.open ("about:blank");
child1.document.write(html);
child1.document.close();
}
</code></pre>

374,156 | <p>I have the following Query and i need the query to fetch data from SomeTable based on the filter criteria present in the Someothertable. If there is nothing present in SomeOtherTable Query should return me all the data present in SomeTable</p>
<p>SQL SERVER 2005</p>
<p>SomeOtherTable does not have any indexes or any constraint all fields are char(50)</p>
<p>The Following Query work fine for my requirements but it causes performance problems when i have lots of parameters.</p>
<p>Due to some requirement of Client, We have to keep all the Where clause data in SomeOtherTable. depending on subid data will be joined with one of the columns in SomeTable.</p>
<p>For example the Query can can be </p>
<pre><code>SELECT
*
FROM
SomeTable
WHERE
1=1
AND
(
SomeTable.ID in (SELECT DISTINCT ID FROM SomeOtherTable WHERE Name = 'ABC' and subid = 'EF')
OR
0=(SELECT Count(1) FROM SomeOtherTable WHERE spName = 'ABC' and subid = 'EF')
)
AND
(
SomeTable.date =(SELECT date FROM SomeOtherTable WHERE Name = 'ABC' and subid = 'Date')
OR
0=(SELECT Count(1) FROM SomeOtherTable WHERE spName = 'ABC' and subid = 'Date')
)
</code></pre>
<p>EDIT----------------------------------------------</p>
<p>I think i might have to explain my problem in detail:</p>
<p>We have developed an ASP.net application that is used to invoke parametrize crystal reports, parameters to the crystal reports are not passed using the default crystal reports method.</p>
<p>In ASP.net application we have created wizards which are used to pass the parameters to the Reports, These parameters are not directly consumed by the crystal report but are consumed by the Query embedded inside the crystal report or the Stored procedure used in the Crystal report.</p>
<p>This is achieved using a table (SomeOtherTable) which holds parameter data as long as report is running after which the data is deleted, as such we can assume that SomeOtherTable has max 2 to 3 rows at any given point of time.</p>
<p>So if we look at the above query initial part of the Query can be assumed as the Report Query and the where clause is used to get the user input from the SomeOtherTable table.</p>
<p>So i don't think it will be useful to create indexes etc (May be i am wrong).</p>

374,157 | <p>We need to interface to 3rd party app, but company behind the app doesn't disclose message protocol and provides only Windows DLL to interface to.</p>
<p>Our application is Linux-based so I cannot directly communicate with DLL. I couldn't find any existing solution so I'm considering writing socket-based bridge between Linux and Windows, however I'm sure it is not such a unique problem and somebody should have done it before.</p>
<p>Are you aware of any solution that allows to call Windows DDL functions from C app on Linux? It can use Wine or separate Windows PC - doesn't matter.</p>
<p>Many thanks in advance.</p>

374,305 | <p>I was wondering if anyone has any preference for referencing images/ css or javascript files in their sites?</p>
<p>The reason I ask is if a client wants to host the site we've writen under a virtual directory, the site usually has to have it's file references changed - even down to url (...image path) in CSS files because we usually develop the site as if it's a root application - sometimes the client doesn't know where they're going to host it until the day before drop-date!</p>
<p>Using ASP.NET we can get around the problem in the forms by referencing items using the '~' when using runat server components or the Url.Content method when using ASP.NET MVC...</p>
<p>So, are there any good solutions for keeping the file references generic or are we faced with having to change the file references everytime?</p>

374,313 | <p>Recently our svn server was changed and we did a svn switch.</p>
<p>Since the working copy had a huge amount of unversioned resources, the working copy got locked and we started switching folder by folder for all folders under svn, which works perfectly fine.</p>
<p>But at the top most level of the repository, when I try to update files, I get the <em>svn: Working copy '.' locked</em> error and cleanup is not helping either. When I do cleanup, I get errors like these - <em>svn: 'content' is not a working copy directory</em></p>
<p>Fresh checkout is NOT an option at all. Are there any other ways to cleanup and release the locks and do the switch completely ?</p>
<p><strong>EDIT:</strong>
The last paragraph in JesperE's answer</p>
<blockquote>
<p>If you get a "not a working copy" when
doing a recursive "svn cleanup" my
guess is that you have a directory
which should be a working copy (i.e.
the .svn directory at the toplevel
says so), but it is missing its own
.svn directory. In that case, you
could try to just remove/move that
directory and then do a local update</p>
</blockquote>
<p>seems to be the solution to the problem in the repository. I have identified those folders and did a fresh checkout of those specific folders alone and wow, the locks are released in the subsequent cleanup! Thanks a lot JesperE !!</p>
<p>But, I still cannot figure out the svn switch error which now reads something like,</p>
<blockquote>
<p>svn: The repository at
'svn://repourl/reponame/foldername'
has uuid 'm/reponame', but the WC
has 'b5b39681-0ff6-784b-ad26-2846b9ea8e7d'</p>
</blockquote>
<p>Any ideas ?</p>

374,398 | <p>Is it safe to assume that event subscribers are called in order of subscription?<br>
Example: </p>
<pre><code>void One(object sender, EventArgs e) {}
void Two(object sender, EventArgs e) {}
event EventHandler foo;
foo += One;
foo += Two;
</code></pre>
<p>Is One() always called before Two() when the event is fired?</p>
<p>Edit:<br>
You should ofcourse not rely on it, I was just thinking. The idea was, that multicast delegates are similary to the COMMAND pattern. So I was just wondering. Ususally you would use a collection that keeps the order for COMMANDs so you can do undo/redo/whatever.</p>

374,417 | <p>I'm trying to save a couple of files to a container file. The files can be modified later which means the container might have to be enlarged. The user should only see this container as a single file in the file system. The application is written in C++ and running on Windows, but the files should be portable to other platforms as well.</p>
<p>The requirements for the container format are:<br>
1. <em>Size</em>: Allow files bigger than 4GB.<br>
2. <em>Portability</em>: It should be feasible to open the container files on other platforms.<br>
3. <em>Performance</em>: When changing a file inside the container, only the "chunks" that represent that specific file may be changed. Especially, there may not be a complete rewrite of that file.<br>
4. <em>Structure</em>: It should provide a directory structure that allows to build a hierarchy of files and directories. </p>
<p>When leaving out requirement 1.) and 2.) compound files (like used by Word and Excel) are a good fit. </p>
<p>Of course, it's possible to design an API that fulfills all the requirements, but I wonder if there is already some open-source solution that tackles the very problem? </p>
<p>Any suggestions?</p>

374,425 | <p>Some of my script are using different encoding, and when I try to combine them, this has becom an issue.</p>
<p>But I can't change the encoding they use, instead I want to change the encodig of the result from script A, and use it as parameter in script B. </p>
<p>So: is there any simple way to change a string from UTF-8 to ISO-88591 in PHP? I have looked at utf_encode and _decode, but they doesn't do what i want. Why doesn't there exsist any "utf2iso()"-function, or similar?</p>
<p>I don't think I have characters that can't be written in ISO-format, so that shouldn't be an huge issue.</p>

374,451 | <p>I have written a custom control, that has several sub panels. I want these sub panels to accept any additional controls dropped on them at design time.</p>
<p>Unfortunately any control that gets dropped at design time ends up on my custom control, not on the panels. This shows in particular if I try to drop a label: The label's blue dots are shown, but it's caption isn't and if I deselect the label, it is no longer visible at all.</p>
<p>simplified code (only one sub panel):</p>
<pre><code>type
TMyContainer = class(TPanel)
p_SubPanel: TPanel;
public
constructor Create(_Owner: TComponent); override;
end;
constructor TMyContainer.Create(_Owner: TComponent);
begin
inherited;
p_SubPanel := TPanel.Create(Self);
p_SubPanel.Parent := Self;
p_SubPanel.Align := alClient;
end;
</code></pre>
<p>What am I doing wrong here?</p>
<p>(Just in case it matters: I am using Delphi 2007.)</p>
<p>[edit]</p>
<p>I have now solved it differently. The component no longer contains panels but refers to external panels. This makes it actually much more flexible, but on the downside it is no longer as intuitive to use.</p>
<p>I would still like to know how to accomplish what I described originally. Isn't there an open source component somewhere that does this, so I can study the source code?</p>

<li>the code is distributed in many packages, there are more that one level of packages </li>
<li>all the test can be run with a single command, for example with <code>python test.py</code></li>
</ol>
<p>I need that the project should use the same test convention for all the code contained. I saw the whole python project but the the various packages are tested with different conventions. For example the setuptools packages uses an ad hoc adaption of unittest library while the other packages doesn't. </p>
<p>I need that the project doesn't use a ad-hoc or a highly customized testing framework, because I want reuse its test architecture in my project.</p>

<p>I use <a href="http://msdn.microsoft.com/en-us/library/y99d1cd3.aspx" rel="nofollow noreferrer">resx</a> files to localize the WinForms, which VS2008 manages quite well.</p>

When I build the solution, Visual Studio automatically generates satellite assemblies for me but only for the WinForms resources in the resx files.
Then, when I use the LocBaml command-line tool, it generates satellite assemblies for me but only for the WPF resources in the xaml files.</p>
<p>I haven't figured out how to merge the two resulting DLLs (WPF & WinForms) into a single satellite assembly.</p>

374,535 | <p>This is a very basic question. I'm just on my mission to learn ASP.NET (C#). I've done classic ASP and PHP before.</p>
<p>For this project I have <strong>ASP.NET 2.0</strong> at my hands.</p>
<p>I have a Web Form that has a <a href="http://www.trirand.com/blog/" rel="nofollow noreferrer">jqGrid</a> Datagrid that I want to feed XML data via AJAX. jqGrid is not the problem here, though. The "problem" is the approach that I should take to generate the XML.</p>
<p>How do I do that in ASP.NET?</p>
<ul>
<li>Do I create a new Web Form that generates that data?</li>
<li>Do I use a new Web Service (that would not return the XML I need, would it?)?</li>
<li>Do I somehow put a function in the existing Web Form that shows the table? If so, how?</li>
</ul>
<p>After that decision is made: How do I output the XML? I don't want to use any XML components of ASP.NET, because it's just plain, simplistic XML with one record after each other. Using System.Xml would be too much overhead to be justified here.</p>
<pre><code><?xml version='1.0' encoding='utf-8'?>
<rows>
<page>1</page>
<total>25</total>
<records>3</records>
<row id='1'>
<cell>Row 1, Column 1</cell>
<cell>Row 1, Column 2</cell>
<cell>Row 1, Column 3</cell>
</row>
<row id='2'>
<cell>Row 2, Column 1</cell>
<cell>Row 2, Column 2</cell>
<cell>Row 2, Column 3</cell>
</row>
<row id='3'>
<cell>Row 3, Column 1</cell>
<cell>Row 3, Column 2</cell>
<cell>Row 3, Column 3</cell>
</row>
</rows>
</code></pre>
<p>From my previous experience with the other scripting languages, I'd just like to print out a stream of XML tags (Response.Write). Will I go to hell if I do so in ASP.NET?</p>

<p>How it works is that the client polls the server every 1 second to see if there are any new actions to take (for example display a message in a channel, or whatever). The polling is done in a thread of its own.</p>
<p>Now, I want the polling thread to open a new MDI form when a channel open action is received (meaning the user has entered a new channel). The thing is, the new form should run on the MAIN program thread, and not on the worker thread.</p>
<p>So basically I'm asking, how do I create a new windows form, and associate it with an already existing thread? (instead of the thread that created it).</p>
<p>Also, if you know of a better way to do this, please tell me. I love improving my program architecture!</p>
<p>Thanks all</p>

374,555 | <p>In my code, I am using JavaScript to fire off an <code>window.open()</code> event on an ASPX page. I´m outputting a file in the <code>Page_Load()</code> event of this page:</p>
<pre><code>Response.Clear();
Response.ClearContent();
Response.ClearHeaders();
Response.Charset = "";
Response.ContentType = "application/octet-stream";
Response.AddHeader("Content-Disposition", "attachment;filename=\"" + filename + "\";");
outputStream.WriteTo(Response.OutputStream);
outputStream.Flush();
outputStream.Close();
Response.Flush();
Response.Close();
</code></pre>
<p>Afterwards i want to close this popup window. But because I have changed my response type, I cant execute <code>window.close()</code> in JavaScript. It will just get appended to the file being given to the users. This thread is the most suitable source i found to solve my problem:</p>
<p><a href="http://forums.asp.net/t/1186371.aspx?PageIndex=1" rel="nofollow noreferrer">Closing window after export to excel</a></p>
<p>But the given answers dont help me, so i am basically stuck. I dont want to tell the user to close the window manually. Do you know how to achieve what i aim for?</p>

374,567 | <p><strong>Final Edit:</strong> I found a solution to the problem (at the bottom of the question).</p>
<p>I've got an Nunit problem that's causing me grief. <strong>Edit:</strong> actually it looks more like a SQLite problem, but I'm not 100% certain yet.</p>
<p>My TestFixture has a setup that generates a random filename that's used as a SQLite database in each of my tests.</p>
<pre><code>[Setup]
public void Setup()
{
// "filename" is a private field in my TestFixture class
filename = ...; // generate random filename
}
</code></pre>
<p>Each of my tests use this construct in each method that accesses the database:</p>
<pre><code>[Test]
public void TestMethod()
{
using (var connection = Connect())
{
// do database activity using connection
// I've tried including this line but it doesn't help
// and is strictly unnecessary:
connection.Close();
}
}
private DbConnection Connect()
{
var connection = DbProviderFactories.GetFactory("System.Data.SQLite").CreateConnection();
connection.ConnectionString = "Data Source=" + filename;
connection.Open();
return connection;
}
</code></pre>
<p>So that one helper method <code>Connect()</code> is used by all the methods. I'm assuming that the <code>using() { }</code> construct is calling <code>Dispose()</code> on the connection at the end of <code>TestMethod()</code> and freeing up the connection to the SQLite database file.</p>
<p>The problem I have is in my [TearDown] method:</p>
<pre><code> [TearDown]
public void Cleanup()
{
File.Delete(filename); // throws an IOException!
}
</code></pre>
<p>With every test I get an exception:</p>
<pre><code>System.IO.IOException: The process cannot access the file 'testdatabase2008-12-17_1030-04.614065.sqlite' because it is being used by another process.
</code></pre>
<p>All of the tests fail when they get to the [TearDown], so I end up with a directory full of temporary databse files (one per test, each with a different name) and a whole bunch of failed tests.</p>
<p>What process is accessing the file? I don't get how a second process could be accessing the file. The <code>connection</code> has completely gone out of scope and been Dispose()d by the time I'm trying to delete the file, so it can't be something SQLite related. Can it?</p>
<p>Note that I get the same result if I run all the tests or just a single test.</p>
<p><strong>Update:</strong> So I tried Dispose()ing of my DbCommand objects as well, since I wasn't doing that (I assumed that every other ADO.NET provider that Dispose()ing the DbConnection also Dispose()s any commands on that connection.) So now they look like:</p>
<pre><code>[Test]
public void TestMethod()
{
using (var connection = Connect())
{
using (var command = connection.CreateCommand())
{
// do database activity using connection
}
}
}
</code></pre>
<p>It didn't make any difference -- the File.Delete() line still throws an IOException. :-(</p>
<p>If I remove that one line in [TearDown] then all my tests pass, but I'm left with a whole bunch of temporary database files.</p>
<p><strong>Another Update:</strong>
This works just fine:</p>
<pre><code>var filename = "testfile.sqlite";
using (var connection = BbProviderFactories.GetFactory("System.Data.SQLite").CreateConnection())
{
connection.ConnectionString = "Data Source=" + filename;
connection.Open();
var createCommand = connection.CreateCommand();
createCommand.CommandText =
"CREATE TABLE foo (id integer not null primary key autoincrement, bar text not null);";
createCommand.ExecuteNonQuery();
var insertCommand = connection.CreateCommand();
insertCommand.CommandText = "INSERT INTO foo (bar) VALUES (@bar)";
insertCommand.Parameters.Add(insertCommand.CreateParameter());
insertCommand.Parameters[0].ParameterName = "@bar";
insertCommand.Parameters[0].Value = "quux";
insertCommand.ExecuteNonQuery();
}
File.Delete(filename);
</code></pre>
<p>I don't understand!</p>
<p><strong>Update:</strong> Solution found:</p>
<pre><code> [TearDown]
public void Cleanup()
{
GC.Collect();
File.Delete(filename);
}
</code></pre>
<p>I ran the unit tests through the debugger, and when the <code>[TearDown]</code> method starts there are definitely no references to the SQLite DbConnection around any more. Forcing a GC must clean them up though. There must be a bug in SQLite.</p>

374,571 | <p>I configured apache on 4 ports (with virtual hosts as some ports used HTTPS) and the aim is to redirect post requests to different servlets running in a TOMCAT instance on some other machine. The calls are made from a <code>httpclient</code> (java client) . When I run the client it throws the error 301 Error: Moved Permanently. Need hints/tips/help on how to solve the this problem.</p>
<p>It would be nice if someone can give me a example. My virtual host (with the re-direction)
looks like something like this </p>
<pre><code><VirtualHost _default_:3334>
RewriteEngine On
RewriteRule ^/$ https://192.168.100.23:38443/Lang/Englangservices/Alapbhet_service
<\VirtualHost>
</code></pre>
<hr>
<p>I am now able to get mod proxy working with mod rewrite and now I dont get the 302 error, but as it always happens to a newbie there is this another problem. </p>
<p>HTTP POST requests are not working. When I issue the post request, the proxy fails as it goes on to look for index.htm. </p>
<p>My httpd.conf snippet</p>
<pre><code><VirtualHost *:3331>

374,573 | <p>I have this Web Application in JSP running on JBoss Application Server. I am using <a href="https://stackoverflow.com/questions/359147/mask-urls-in-jsp">Servlets for friendly urls</a>. I'm sending search parameters through my JSP's and Servlets. I am using a form with a text box, the Servlet </p>
<p>The first Servlet uses <code>request.getParameter()</code> to get the text, and sends it to another Servlet with <code>response.sendRedirect</code> (masking the URL to something "friendly"). This final Servlet uses <code>request.getRequestDispatcher().forward()</code> to send the parameters to the JSP in the "ugly" way: <code>searchResults.jsp?searchParameters=Parameters</code>.</p>
<p>Now, when the Search Results page is displayed, the URL displays the correct search term with "friendly url". Example: <code>http://site.com/search/My-Search-Query</code> even when using special characters like: <code>http://site.com/search/Busqué-tildes-y-eñies</code>. But when I try to use that search term in my JSP, the special characters are not displayed correctly.</p>
<p>The whole system uses i18n, and we've had no problems with special characters so far. But when the information is sent through the form (say from index.jsp to searchResults.jsp) special characters are not correctly displayed:</p>
<p><code>á - á</code> <br/>
<code>é - é</code><br/>
<code>í - Ã</code><br/>
<code>ó - ó</code><br/>
<code>ú - ú</code><br/>
<code>ñ - ñ</code><br/></p>
<p>The whole code base is supposed to be in UTF-8, but apparently I'm missing something when passing the parameters. As I said, they are correctly displayed in the URL, but not inside the JSP.</p>
<p>I was thinking of converting those <code>á</code> manually, but I guess there's a better way to do it correctly, using the correct encoding. Besides, there can be new characters later which I may not be aware of right now (French, Spanish, etc.)</p>
<p>Just in case, I'll let you know I have these lines on each JSP:</p>
<p><code><?xml version="1.0" encoding="UTF-8" ?></code><br/>
<code><%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%></code></p>
<p><strong>EDIT</strong></p>
<p>Thanks for your answers. I tried a few things, but nothing has fixed the problem.</p>
<p>Here's what I've done:</p>
<ul>
<li><p>I added a ServletRequestListener which sets the session's character encoding to UTF-8, and a Filter for every Http request, which does the same.</p></li>
<li><p>As I said, everything in the JSPs is encoded with UTF-8 (see headers in question). </p></li>
<li><p>I printed the Servlets' character encoding to the console, which were null by default, set them to UTF-8 like @kgiannakakis and @saua said. </p></li>
</ul>
<p>None of these actions fixes the problem. I'm wondering if there's something else wrong with this...</p>

374,626 | <p>I am writing a program in Python, and I realized that a problem I need to solve requires me, given a set <code>S</code> with <code>n</code> elements (|S|=n), to test a function on all possible subsets of a certain order <code>m</code> (i.e. with <em>m</em> number of elements). To use the answer to produce a partial solution, and then try again with the next order m=m+1, until m=n.</p>
<p>I am on my way to write a solution of the form:</p>
<pre><code>def findsubsets(S, m):
subsets = set([])
...
return subsets
</code></pre>
<p>But knowing Python I expected a solution to be already there.</p>
<p>What is the best way to accomplish this?</p>

<p><code>obj</code> now refers to an object of type <code>bool</code> (<code>System.Boolean</code>) with value equal to <code>true</code>. What I really wanted was an object of type <code>Nullable<bool></code></p>
<p>So now as a work around I decided to check if o is nullable and create a nullable wrapper around obj.</p>

<p>I'm asking because the compilation is too long, and kept up-to-date by a continuous integration server ; and I'm chasing after an issue with the unit tests. </p>

374,684 | <p>I am looking for a simple templating solution for ruby, i.e. something that will let me write php-like or jsp-like templates (html with embedded code tags), but in ruby.
jsp is no good for me, because most hosting services (I'm on dreamhost) don't support it on their default package, and it's a little cumbersome to set up.
php is easy to get up and running, but I hate the syntax, and I miss all the greatness of ruby.</p>
<p>erb seems to be close to what I'm looking for, but how do I set up the server (htaccess file etc) to serve it?</p>
<p>P.S. Please do not suggest Ruby On Rails. It's a huge overkill for what I'm doing.</p>
