272,361 | <p>I wrote a PHP code like this</p>
<pre><code>$site="http://www.google.com";
$content = file_get_content($site);
echo $content;
</code></pre>
<p>But when I remove "http://" from <code>$site</code> I get the following warning:</p>
<blockquote>
<p>Warning:
file_get_contents(www.google.com)
[function.file-get-contents]: failed
to open stream:</p>
</blockquote>
<p>I tried <code>try</code> and <code>catch</code> but it didn't work.</p>

272,368 | <p>If I have a method with a parameter that's an interface, whats the fasts way to see if the interface's reference is of a specific generic type?</p>
<p>More specifically, if I have:</p>
<pre><code>interface IVehicle{}
class Car<T> : IVehicle {}
CheckType(IVehicle param)
{
// How do I check that param is Car<int>?
}
</code></pre>
<p>I'm also going to have to cast after the check. So if there is a way to kill 2 birds with one stone on this one let me know.</p>

272,387 | <p>In SQL Server 2005, I want to print out a blank line with the PRINT statement, however, when I run</p>
<pre><code>PRINT ''
</code></pre>
<p>it actually prints a line with a single space.</p>
<p>Does anyone know if it's possible to just print a blank line without the space?</p>
<p>If I print a new line character, it doesn't print a space, but I end up with two new lines.</p>

272,409 | <p>I'd like to be able to place all my ASP Classic include files outside of the web root. This assures no include files can be called directly via the URL. </p>
<p>What is the best way to accomplish this?</p>
<p>I know I can use a <a href="http://msdn.microsoft.com/en-us/library/zwk103ab.aspx" rel="nofollow noreferrer">virtual directory</a> to reference an includes folder outside of web root, but doesn't that still allow direct access to that directory via the URL? Perhaps I'm misunderstanding the nature of virtual directories.</p>

272,428 | <p>What is the meaning of the concepts 'covariance' and 'contravariance'?</p>
<p>Given 2 classes, <strong>Animal</strong> and <strong>Elephant</strong> (which inherits from <strong>Animal</strong>), my understanding is that you would get a run-time errors if you try and put an Elephant into an array of Animals, and this happens because Elephant is "bigger" (more specific) than Animal. But could you place an Animal into an array of Elephant, seeing how Elephant is guaranteed to contain the Animal properties?</p>

272,429 | <p>I have 4 different named instances of SQL Server 2005 on a single server (for testing purposes). There is no default instance on the server.</p>
<p>Because I will eventually need to allow communication to these instances across the firewall, I have set the ports of each instance statically listening on all IPs for the server.</p>
<p><strong>Edit</strong>: TCP/IP, Shared Memory, and Named Pipes are all enabled. VIA is disabled. The ports are statically set for All IPs on the TCP/IP protocol, and each named instance is using a separate port.</p>
<p>I also have SQLBrowser service running, and all instances are configured to allow remote connections.</p>
<p>One instance is set to the default port (1433), and it works fine.</p>
<p>The other instances, however, exhibit very strange behavior. When I connect to them using the Sql Server Management Studio within the network (so I'm not even crossing the firewall yet), the studio connects without complaining. However, as soon as I try to expand the Database list for the instance, or refresh the instance, or pretty much anything else, I get the following error:</p>

272,438 | <p>Suppose I create a table in Postgresql with a comment on a column:</p>
<pre><code>create table t1 (
c1 varchar(10)
);
comment on column t1.c1 is 'foo';
</code></pre>
<p>Some time later, I decide to add another column:</p>
<pre><code>alter table t1 add column c2 varchar(20);
</code></pre>
<p>I want to look up the comment contents of the first column, and associate with the new column:</p>
<pre><code>select comment_text from (what?) where table_name = 't1' and column_name = 'c1'
</code></pre>
<p>The (what?) is going to be a system table, but after having looked around in pgAdmin and searching on the web I haven't learnt its name.</p>
<p>Ideally I'd like to be able to:</p>
<pre><code>comment on column t1.c1 is (select ...);
</code></pre>
<p>but I have a feeling that's stretching things a bit far. Thanks for any ideas.</p>
<p>Update: based on the suggestions I received here, I wound up writing a program to automate the task of transferring comments, as part of a larger process of changing the datatype of a Postgresql column. You can read about that <a href="http://wirespeed.wordpress.com/2008/11/07/alter-column-type-postgres/" rel="nofollow noreferrer">on my blog</a>.</p>

272,457 | <p>I'm looking into tightening up our ad code by moving it to an external jQuery script, but I obviously still need some HTML to target the ad to. So I was wondering if I can target a noscript element (or within a noscript element) since I'm going to have to leave that on the page anyway, or if I need to have some other element for the JavaScript to target?</p>
<pre><code><noscript>
<div class="ad"><a href="foo"><img src="bar" alt="ad" /></a></div>
</noscript>
</code></pre>
<p>My intention would be to change or strip the noscript element.</p>

272,458 | <p>I want my validation.xml to only check for a null if certain options are selected from a dropdown. So far I have</p>
<pre><code><field property="empFDServiceStartDate" depends="requiredif, date">
<arg0 key="Service Start date" resource="false"/>
<var>
<var-name>field[0]</var-name>
<var-value>moverChangeType</var-value>
</var>
<var>
<var-name>fieldTest[0]</var-name>
<var-value>EQUALS</var-value>
</var>
<var>
<var-name>fieldValue[0]</var-name>
<var-value>Conversion</var-value>
</var>
</field>
</code></pre>
<p>When the value "Conversion" is selected from the moverChangeType dropdown, I was hoping that the empFDServiceStartDate field would be checked for nulls before being saved. At the moment this doesn't work and it allows me to save nulls.</p>
<p>Any idea?</p>
<p>I am tied to struts 1.1 and therefore can't use newer commands.</p>

272,504 | <p>I am using the following code fragment in a php script to safely update a shared resource. </p>
<pre><code>$lock_id = sem_get( ftok( 'tmp/this.lock', 'r'));
sem_acquire($lock_id)
//do something
sem_release($lock_id)
</code></pre>
<p>When I stress test this code with large number of requests I get an error:</p>
<pre><code>Warning: semop() failed acquiring SYSVSEM_SETVAL for key 0x1e: No space left on device in blahblah.php on line 1293
</code></pre>
<p>php sources show the following code for failed acquiring SYSVSEM_SETVAL</p>
<pre><code>while (semop(semid, sop, 3) == -1) {
if (errno != EINTR) {
php3_error(E_WARNING, "semop() failed acquiring SYSVSEM_SETVAL for key 0x%x: %s", key, strerror(errno));
break;
}
}
</code></pre>
<p>which means semop fails with EINTR. man page reveals that the semop() system call was interrupted by a signal. </p>
<p>My question is can I safely ignore this error and retry sem_acquire? </p>

272,511 | <p>Is it possible to write a GUI from inside a function?</p>
<p>The problem is that the callback of all GUI-functions are evaluated in the global workspace. But functions have their own workspace and can not access variables in the global workspace. Is it possible to make the GUI-functions use the workspace of the function? For example:</p>
<pre><code>function myvar = myfunc()
myvar = true;
h_fig = figure;
% create a useless button
uicontrol( h_fig, 'style', 'pushbutton', ...
'string', 'clickme', ...
'callback', 'myvar = false' );
% wait for the button to be pressed
while myvar
pause( 0.2 );
end
close( h_fig );
disp( 'this will never be displayed' );
end
</code></pre>
<p>This event-loop will run indefinitely, since the callback will not modify <code>myvar</code> in the function. Instead it will create a new <code>myvar</code> in the global workspace.</p>

272,523 | <p>I am using winsock and C++ to set up a server application. The problem I'm having is that the call to <code>listen</code> results in a first chance exception. I guess normally these can be ignored (?) but I've found others having the same issue I am where it causes the application to hang every once in a while. Any help would be greatly appreciated.</p>
<p>The first chance exception is:</p>
<blockquote>
<p>First-chance exception at 0x*12345678* in <em>MyApp</em>.exe: 0x000006D9: There are no more endpoints available from the endpoint mapper.</p>
</blockquote>
<p>I've found some evidence that this could be cause by the socket And the code that I'm working with is as follows. The exception occurs on the call to <code>listen</code> in the fifth line from the bottom.</p>
<pre><code> m_accept_fd = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);
if (m_accept_fd == INVALID_SOCKET)
{
return false;
}
int optval = 1;
if (setsockopt (m_accept_fd, SOL_SOCKET, SO_REUSEADDR,
(char*)&optval, sizeof(optval)))
{
closesocket(m_accept_fd);
m_accept_fd = INVALID_SOCKET;
return false;
}
struct sockaddr_in local_addr;
local_addr.sin_family = AF_INET;
local_addr.sin_addr.s_addr = INADDR_ANY;
local_addr.sin_port = htons(m_port);

272,528 | <p>I was thinking of adding some <strong>Achievements</strong> to our internal bug-tracking and time logging system. It's connected to an SQL Server back-end.</p>
<p>At first I thought that the system could be run on the database, using triggers to, for example, know when:</p>
<ul>
<li>you've logged 1000 hours</li>
<li>created 1000 tickets</li>
<li>closed your own ticket</li>
<li>worked on a ticket that has been not touched in a while.</li>
<li>etc (you know - database-ish things)</li>
</ul>
<p>But then I realized that I would also want purely <strong>front-end achivements</strong> </p>
<ul>
<li>used the advanced search abiltiy</li>
<li>sorted by a column</li>
<li>reset settings to default</li>
<li>searched 500 times</li>
</ul>
<p>It seems like the logic of every achievement must be hand coded. Could anyone imagine an some sort of <em>Achievements Rules Engine</em>, that you for example create scripts for?</p>
<p>And how to store them? If the achievement is:</p>
<ul>
<li>change column sort order 50 times in one session</li>
</ul>
<p>that would imply that every time they sort a listview column it updates the database. </p>
<p>Any thoughts on this Win32 application design problem? I don't think that the <a href="http://en.wikipedia.org/wiki/Gang_of_Four" rel="nofollow noreferrer">Gang of Four</a> have an Achievements <strong>design pattern</strong>.</p>
<hr>
<p><strong>Note:</strong> It's a Win32 client application, not a web-site.</p>
<hr>
<p>i definetly like the idea of an eventing system. Various actions the user takes can raise events through a single eventing object:</p>
<pre><code>protected void TimeEntriesListView_ColumnSort(object sender, EventArgs e)
{
_globalListener.RaiseEvent(EventType.ListViewColumnSort, sender, e);
}
protected void TimeEntriesListView_ColumnDrag(object sender, EventArgs e)
{
_globalListener.RaiseEvent(EventType.ListViewColumnDrag, sender, e);
}
</code></pre>
<p>That object can then have logic added to it to decide which events it wants to count. But more reasonably, various event listeners can attached to the central event listener, and have their custom achievement logic.</p>

272,544 | <p>I'm reading Erica Sadun's <em>iPhone Developer's Cookbook</em>, and ran into a question.</p>
<p>She says in the book that the way to find the user's Documents directory is with the code:</p>
<pre><code>[NSHomeDirectory() stringByAppendingPathComponent:@"Documents"];
</code></pre>
<p>but that seems slightly brittle, and dissimiliar to the normal Mac way of doing it, which would be:</p>
<pre><code>NSSearchPathForDirectoriesInDomains(NSDocumentsDirectory, NSUserDomainMask, YES);
</code></pre>
<p>Are there any particular reasons to use one over the other?</p>

272,618 | <p>I've created a MATLAB class, something like:</p>
<pre><code>classdef myclass
properties
x_array = [];
end
methods
function increment(obj,value)
obj.x_array = [obj.x_array ; value);
end
end
end
</code></pre>
<p>The problem is, the property <code>x_array</code> is never modified when I invoke the <code>increment()</code> function:
ex:</p>
<pre><code>>>s = myclass
>>increment(s,5)
>>s.x_array
ans = []
</code></pre>
<p>I did some research, and I reached a conclusion that this is because of MATLAB using Lazy Copy for objects, making my class inherit the HANDLE class should have solved this, but it didn't, does anybody know why this is happening? And if extending the handle class is indeen the solution, isn't this the right way to do it:</p>
<pre><code>classdef myclass < handle
</code></pre>
<p>or are there any extra steps?</p>

272,635 | <p>I'm doing some shennanigans with jQuery to put little plus/minus icons next to my expanders. Its similar to the windows file trees, or firebugs code expanders.</p>
<p>It works, but its not specific enough. </p>
<p>Hopefully this makes sense...</p>
<pre><code>$('div.toggle').hide();//hide all divs that are part of the expand/collapse
$('ul.product-info li a').toggle(function(event){
event.preventDefault();
$(this).next('div').slideToggle(200);//find the next div and sliiiide it
$('img.expander').attr('src','img/content/info-close.gif');//this is the part thats not specific enough!!!
},function(event) { // opposite here
event.preventDefault();
$(this).next('div').slideToggle(200);
$('img.expander').attr('src','img/content/info-open.gif');
});
<ul class="product-info">
<li>
<a class="img-link" href="#"><img class="expander" src="img/content/info-open.gif" alt="Click to exand this section" /> <span>How it compares to the other options</span>
</a>
<div class="toggle"><p>Content viewable when expanded!</p></div>
</li>
</ul>
</code></pre>
<p>There are loads of <code>$('img.expander')</code> tags on the page, but I need to be specific. I've tried the next() functionality ( like I've used to find the next div), but it says that its undefined. How can I locate my specific img.expander tag? Thanks.</p>
<p>EDIT, updated code as per Douglas' solution:</p>
<pre><code>$('div.toggle').hide();
$('ul.product-info li a').toggle(function(event){
//$('#faq-copy .answer').hide();
event.preventDefault();
$(this).next('div').slideToggle(200);
$(this).contents('img.expander').attr('src','img/content/info-close.gif');
//alert('on');
},function(event) { // same here
event.preventDefault();
$(this).next('div').slideToggle(200);
$(this).contents('img.expander').attr('src','img/content/info-open.gif');
});
</code></pre>

272,644 | <p>I have a class called <code>Ship</code> and a class called <code>Lifeboat</code></p>
<p>Lifeboat inherits from Ship.</p>
<p>Ship contains a method called <code>Validate()</code> which is called before save and it has an abstract method called <code>FurtherValidate()</code> which it calls from Validate. The reason this is in place is so when you call validate on the base it also validates the class that is inheriting. So we have</p>
<pre><code>public class Ship
public bool Validate()
{
//validate properties only found on a ship
FurtherValidate();
}
public abstract bool FurtherValidate();
</code></pre>
<p>So <code>Lifeboat</code> has </p>
<pre><code>public override bool FurtherValidate()
{
//validate properties only found on a lifeboat
}
</code></pre>
<p>This means anyone implementing <code>Ship</code> also needs to provide their own validation for their class and it's guaranteed to be called on the save as the base ship. <code>Validate()</code> is called which in turns calls the inherited validate.</p>
<p>How can we re work this so we still force inherited classes to implement <code>FurtherValidate()</code> but <code>FurtherValidate()</code> can never be called by the programmer. Currently you can called <code>Lifeboat.FurtherValidate()</code> and I want to somehow prevent this.</p>

272,665 | <p>First of all, some background.</p>
<p>We have an order processing system, where staff enter billing data about orders in an app that stores it in a sql server 2000 database. This database isn't the real billing system: it's just a holding location so that the records can be run into a mainframe system via a nightly batch process. </p>
<p>This batch process is a canned third party package provided by an outside vendor. Part of what it's supposed to do is provide a report for any records that were rejected. The reject report is worked manually.</p>
<p>Unfortunately, it turns out the third party software doesn't catch all the errors. We have separate processes that pull back the data from the mainframe into another table in the database and load the rejected charges into yet another table. </p>
<p>An audit process then runs to make sure everything that was originally entered by the staff can be accounted for somewhere. This audit takes the form of an sql query we run, and it looks something like this:</p>
<pre><code>SELECT *
FROM [StaffEntry] s with (nolock)
LEFT JOIN [MainFrame] m with (nolock)
ON m.ItemNumber = s.ItemNumber
AND m.Customer=s.Customer
AND m.CustomerPO = s.CustomerPO -- purchase order
AND m.CustPORev = s.CustPORev -- PO revision number
LEFT JOIN [Rejected] r with (nolock) ON r.OrderID = s.OrderID
WHERE s.EntryDate BETWEEN @StartDate AND @EndDate
AND r.OrderID IS NULL AND m.MainFrameOrderID IS NULL
</code></pre>
<p>That's heavily modified, of course, but I believe the important parts are represented. The problem is that this query is starting to take too long to run, and I'm trying to figure out how to speed it up.</p>
<p>I'm pretty sure the problem is the JOIN from the <code>StaffEntry</code> table to the <code>MainFrame</code> table. Since both hold data for every order since the beginning of time (2003 in this system), they tend to be a little large. The <code>OrderID</code> and <code>EntryDate</code> values used in the <code>StaffEntry</code> table are not preserved when imported to the mainframe, which is why that join is a little more complicated. And finally, since I'm looking for records in the <code>MainFrame</code> table that don't exist, after doing the JOIN we have that ugly <code>IS NULL</code> in the where clause.</p>
<p>The <code>StaffEntry</code> table is indexed by EntryDate (clustered) and separately on Customer/PO/rev. <code>MainFrame</code> is indexed by customer and the mainframe charge number (clustered, this is needed for other systems) and separately by customer/PO/Rev. <code>Rejected</code> is not indexed at all, but it's small and testing shows it's not the problem. </p>
<p>So, I'm wondering if there is another (hopefully faster) way I can express that relationship?</p>

272,674 | <p>I am looking for a data structure that operates similar to a hash table, but where the table has a size limit. When the number of items in the hash reaches the size limit, a culling function should be called to get rid of the least-retrieved key/value pairs in the table.</p>
<p>Here's some pseudocode of what I'm working on:</p>
<pre><code>class MyClass {
private Map<Integer, Integer> cache = new HashMap<Integer, Integer>();
public int myFunc(int n) {
if(cache.containsKey(n))
return cache.get(n);
int next = . . . ; //some complicated math. guaranteed next != n.
int ret = 1 + myFunc(next);
cache.put(n, ret);
return ret;
}
}
</code></pre>
<p>What happens is that there are some values of <code>n</code> for which <code>myFunc()</code> will be called lots of times, but many other values of <code>n</code> which will only be computed once. So the cache could fill up with millions of values that are never needed again. I'd like to have a way for the cache to automatically remove elements that are not frequently retrieved.</p>
<p>This feels like a problem that must be solved already, but I'm not sure what the data structure is that I would use to do it efficiently. Can anyone point me in the right direction?</p>
<hr>
<p><strong>Update</strong> I knew this had to be an already-solved problem. It's called an LRU Cache and is easy to make by extending the LinkedHashMap class. Here is the code that incorporates the solution:</p>
<pre><code>class MyClass {
private final static int SIZE_LIMIT = 1000;
private Map<Integer, Integer> cache =
new LinkedHashMap<Integer, Integer>(16, 0.75f, true) {
protected boolean removeEldestEntry(Map.Entry<Integer, Integer> eldest)
{
return size() > SIZE_LIMIT;
}
};
public int myFunc(int n) {
if(cache.containsKey(n))
return cache.get(n);
int next = . . . ; //some complicated math. guaranteed next != n.
int ret = 1 + myFunc(next);
cache.put(n, ret);
return ret;
}
}
</code></pre>

272,694 | <p>I've got a strange problem with indexing PDF files in SQL Server 2005, and hope someone can help. My database has a table called MediaFile with the following fields - MediaFileId int identity pk, FileContent image, and FileExtension varchar(5). I've got my web application storing file contents in this table with no problems, and am able to use full-text searching on doc, xls, etc with no problems - the only file extension not working is PDF. When performing full-text searches on this table for words which I know exist inside of PDF files saved in the table, these files are not returned in the search results.</p>
<p>The OS is Windows Server 2003 SP2, and I've installed <a href="http://www.adobe.com/support/downloads/detail.jsp?ftpID=2611" rel="noreferrer">Adobe iFilter 6.0</a>. Following the instructions on <a href="http://weblogs.asp.net/wallym/archive/2005/02/28/382060.aspx" rel="noreferrer">this blog entry</a>, I executed the following commands:</p>
<pre><code>exec sp_fulltext_service 'load_os_resources', 1;
exec sp_fulltext_service 'verify_signature', 0;
</code></pre>
<p>After this, I restarted the SQL Server, and verified that the iFilter for the PDF extensions is installed correctly by executing the following command:</p>
<pre><code>select document_type, path from sys.fulltext_document_types where document_type = '.pdf'
</code></pre>
<p>This returns the following information, which looks correct:</p>
<blockquote>
<p>document_type: .pdf<br/>
path: C:\Program Files\Adobe\PDF IFilter 6.0\PDFFILT.dll</p>
</blockquote>
<p>Then I (re)created the index on the MediaFile table, selecting FileContent as the column to index and the FileExtension as its type. The wizard creates the index and completes successfully. To test, I'm performing a search like this:</p>
<pre><code>SELECT MediaFileId, FileExtension FROM MediaFile WHERE CONTAINS(*, '"house"');
</code></pre>
<p>This returns DOC files which contain this term, but not any PDF files, although I know that there are definitely PDF files in the table which contain the word <em>house</em>.</p>
<p>Incidentally, I got this working once for a few minutes, where the search above returned the correct PDF files, but then it just stopped working again for no apparent reason.</p>
<p>Any ideas as to what could be stopping SQL Server 2005 from indexing PDF's, even though Adobe iFilter is installed and appears to be loaded?</p>

272,726 | <p>I have a Stored Procedure that is constantly failing with the error message "Timeout expired," on a specific user.</p>
<p>All other users are able to invoke the sp just fine, and even I am able to invoke the sp normally using the Query Analyzer--it finishes in just 10 seconds. However with the user in question, the logs show that the ASP always hangs for about 5 minutes and then aborts with a timeout.</p>
<p>I invoke from the ASP page like so "<code>EXEC SP_TV_GET_CLOSED_BANKS_BY_USERS '006111'</code>"</p>
<p>Anybody know how to diagnose the problem? I have already tried looking at deadlocks in the DB, but didn't find any.</p>

272,750 | <p>I am writing an application which blocks on input from two <code>istreams</code>.</p>
<p>Reading from either <code>istream</code> is a synchronous (blocking) call, so, I decided to create two <code>Boost::thread</code>s to do the reading.</p>
<p>Either one of these threads can get to the "end" (based on some input received), and once the "end" is reached, both input streams stop receiving. Unfortunately, I cannot know which will do so.</p>
<p>Thus, I cannot <code>join()</code> on both threads, because only one thread (cannot be predetermined which one) will actually return (unblock).</p>
<p>I must somehow force the other to exit, but it is blocked waiting for input, so it cannot itself decide it is time to return (condition variables or what not).</p>
<p>Is their a way to either:</p>
<ul>
<li>Send a signal a boost::thread, or</li>
<li>Force an <code>istream</code> to "fail", or</li>
<li>Kill a Boost::thread?</li>
</ul>
<p>Note:</p>
<ul>
<li>One of the <code>istreams</code> is <code>cin</code></li>
<li>I am trying to restart the process, so I cannot close the input streams in a way that prohibits reseting them.</li>
</ul>
<p>Edit:</p>
<ul>
<li>I do know when the "end" is reached, and I do know which thread has successfully finished, and which needs to be killed. Its the killing I need to figure out (or a different strategy for reading from an istream).</li>
<li>I need both threads to exit and cleanup properly :(</li>
</ul>
<p>Thanks!</p>

272,765 | <p>I've created a c# webservice that allows our front end support teams to view and update a few selected Active Directory values using system.directoryservices</p>
<p>Fields that I want to update are [job] title, department, telephone and employeeid.</p>
<p>I can use a service account with "delegates rights" to update [job] title, department, telephone etc. but when I try to update employeeid I get an "not authorised" error message.</p>
<p>If I use a domain admin account then the same code works fine.</p>
<p>I don't want to use a domain admin account for this webservice, so what privileges do I need?</p>

272,783 | <p>I have a delphi (Win32) web application that can run either as a CGI app, ISAPI or Apache DLL. I want to be able to generate a unique filename prefix (unique for all current requests at a given moment), and figure that the best way to do this would be to use processID (to handle CGI mode) as well as threadID (to handle dll mode).</p>
<p>How would I get a unique Process ID and Thread ID in Delphi?</p>
<p>Will these be unique in a Multi-Core/Multi-Processor situation (on a single webserver machine)?</p>
<p><em>Edit: please note that I was advised against this approach, and thus the accepted answer uses a different method to generate temporary filenames</em></p>

272,791 | <p>I'm not that familiar with WCF, but I thought I'll learn while trying to consume an existing service.</p>
<p>One of the REST APIs I thought of was the <a href="http://apiwiki.twitter.com/REST+API+Documentation" rel="noreferrer">Twitter API</a>. I thought of developing a WPF client that will just output to the screen the last 5 tweets by a certain Twitter user.</p>
<p>I was wondering if someone could please briefly outline the steps I need to take in Visual Studio to consume these services, using WCF (classes, wizards, proxies etc.).I already know how to just call them using a web request and parse the XML that returns - I really want to see the WCF part at work.</p>
<p>Thanks in advance to anyoine who helps further my education :)</p>

272,803 | <p>I have an interesting problem and would appreciate your thoughts for the best solution.
I need to parse a set of logs. The logs are produced by a multi-threaded program and a single process cycle produces several lines of logs.</p>
<p>When parsing these logs I need to pull out specific pieces of information from each process - naturally this information is across the multiple lines (I want to compress these pieces of data into a single line). Due to the application being multi-threaded, the block of lines belonging to a process can be fragmented as other processes at written to the same log file at the same time.</p>
<p>Fortunately, each line gives a process ID so I'm able to distinguish what logs belong to what process.</p>
<p>Now, there are already several parsers which all extend the same class but were designed to read logs from a single threaded application (no fragmentation - from original system) and use a readLine() method in the super class. These parsers will keep reading lines until all regular expressions have been matched for a block of lines (i.e. lines written in a single process cycle).</p>
<p>So, what can I do with the super class so that it can manage the fragmented logs, and ensure change to the existing implemented parsers is minimal?</p>

272,826 | <p>I've got a PHP command line program running. And I want to connect to a mysql shell straight from PHP. I've done this before in Python using os.execvp But I can't get the same thing to work in PHP.</p>
<p>I've tried the following functions:</p>
<ul>
<li>system</li>
<li>passthru</li>
<li>exec</li>
<li>shell_exec</li>
</ul>
<p>example:</p>
<pre><code>system('mysql -u root -pxxxx db_name');
</code></pre>
<p>But they all seem to wait for mysql to exit and return something. What I really want is for PHP to launch the mysql shell and then exit it self. any ideas?</p>

272,868 | <p>I thought that it would be fun to present some classic CS problems and let people show their algorithm optimization skills. The hope is that we get to see some clever techniques to solve abstract problems that we may be able to implement in practice.</p>
<p>Ideally solutions would be presented in pseudo code with a big O classification. Proof of that classification is gravy. On to the problem:</p>
<p>There are N closed lockers and N students present. The first student opens each locker. The second student opens or closes every second locker. This continues where the nth student opens and closes every nth locker. After N students what lockers are open? How many lockers are open?</p>

<p>char *strtok(char *s1, const char *s2)</p>
<p>repeated calls to this function break string s1 into "tokens"--that is
the string is broken into substrings,
each terminating with a '\0', where
the '\0' replaces any characters
contained in string s2. The first call
uses the string to be tokenized as s1;
subsequent calls use NULL as the first
argument. A pointer to the beginning
of the current token is returned; NULL
is returned if there are no more
tokens.</p>
</blockquote>
<p>Hi, </p>
<p>I have been trying to use <code>strtok</code> just now and found out that if I pass in a <code>char*</code> into <code>s1</code>, I get a segmentation fault. If I pass in a <code>char[]</code>, <code>strtok</code> works fine. </p>
<p>Why is this?</p>
<p>I googled around and the reason seems to be something about how <code>char*</code> is read only and <code>char[]</code> is writeable. A more thorough explanation would be much appreciated.</p>

272,908 | <p>I'm trying to install RSpec as a gem after having it installed as a plugin. I've gone ahead and followed the directions found here <a href="http://github.com/dchelimsky/rspec-rails/wikis" rel="noreferrer">http://github.com/dchelimsky/rspec-rails/wikis</a> for the section titled <strong>rspec and rspec-rails gems</strong>. When I run <code>ruby script/generate rspec</code>, I get the error <code>Couldn't find 'rspec' generator</code>. Do only the plugins work? If so, why do they even offer the gems for rspec and rspec-rails? I'm running a frozen copy of Rails 2.1.2, and the version of rpsec and rspec-rails I'm using is the newest for today (Nov 7, 2008) 1.1.11.</p>
<p>EDIT Nov 12, 2008
I have both the rspec and rspec-rails gems installed. I've unpacked the gems into the vender/gems folder. Both are version 1.1.11.</p>

272,928 | <p>I need to generate buttons initially based on quite a processor and disk intensive search. Each button will represent a selection and trigger a postback. My issue is that the postback does not trigger the command b_Command. I guess because the original buttons have not been re-created. I cannot affort to execute the original search in the postback to re-create the buttons so I would like to generate the required button from the postback info.</p>
<p>How and where shoud I be doing this? Should I be doing it before Page_Load for example? How can I re-construct the CommandEventHandler from the postback - if at all?</p>
<pre><code> namespace CloudNavigation
{
public partial class Test : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (IsPostBack)
{
// how can I re-generate the button and hook up the event here
// without executing heavy search 1
}
else
{
// Execute heavy search 1 to generate buttons
Button b = new Button();
b.Text = "Selection 1";
b.Command += new CommandEventHandler(b_Command);
Panel1.Controls.Add(b);
}
}
void b_Command(object sender, CommandEventArgs e)
{
// Execute heavy search 2 to generate new buttons
Button b2 = new Button();
b2.Text = "Selection 2";
b2.Command += new CommandEventHandler(b_Command);
Panel1.Controls.Add(b2);
}
}

272,941 | <p>I've done development in both VB6 and VB.NET, and I've used ADODB objects in VB6 to handle recordset navigation (i.e. the MoveFirst, MoveNext, etc. methods), and I have used ADO.NET to handle queries in a row-by-row nature (i.e For Each Row In Table.Rows ...)</p>
<p>But now I seem to have come to a dilemma. I am now building a program in VB.NET where I need to use the equivalent functionality of the Move commands of the old Recordset object. Does VB.NET have some sort of object that supports this functionality, or do I have to resort to using the old ADODB COM object?</p>
<p>Edit: Just for clarification, I want the user to be able to navigate through the query moving forwards or backwards. Looping through the rows is a simple task.</p>

272,964 | <p>If I have a function that returns an object, but this return value is never used by the caller, will the compiler optimize away the copy? (Possibly an always/sometimes/never answer.)</p>
<p>Elementary example:</p>
<pre><code>ReturnValue MyClass::FunctionThatAltersMembersAndNeverFails()
{
//Do stuff to members of MyClass that never fails
return successfulResultObject;
}
void MyClass::DoWork()
{
// Do some stuff
FunctionThatAltersMembersAndNeverFails();
// Do more stuff
}
</code></pre>
<p>In this case, will the <code>ReturnValue</code> object get copied at all? Does it even get constructed? (I know it probably depends on the compiler, but let's narrow this discussion down to the popular modern ones.)</p>
<p>EDIT: Let's simplify this a bit, since there doesn't seem to be a consensus in the general case. What if <code>ReturnValue</code> is an int, and we return 0 instead of <code>successfulResultObject</code>?</p>

272,970 | <p>It seems that all of the documentation I can find about OpenGL-ES says something to the effect of "OpenGL-ES is just like OpenGL, but without a lot of stuff. For example, there's no glBegin or glEnd."</p>
<p>Ok, that's great. So, what ELSE isn't there any of? Or is there a list of what's <em>in</em>? Or maybe a porting guide?</p>

272,973 | <p>I have a single form for editing an event, in which the user can (a) edit the details of the event (title, description, dates, etc.) in a FormView and (b) view and edit a ListView of contacts who are registered for the event. </p>
<p>Here's my LinqDataSource, which allows me to add and remove contacts to the event. </p>
<pre><code><asp:linqdatasource runat="server" id="ContactsDatasource" contexttypename="Db" tablename="ContactsCalendarEventsXtabs" autogeneratewhereclause="true" enabledelete="true" enableinsert="true">
<whereparameters>
<asp:querystringparameter name="CalendarEventID" querystringfield="id" type="Int32" />
</whereparameters>
<insertparameters>
<asp:querystringparameter name="CalendarEventID" querystringfield="id" type="Int32" />
</insertparameters>
</asp:linqdatasource>
</code></pre>
<p>This works fine, but of course it persists the changes to the database as they're made; and it only works when the event has already been created. Ideally, I'd like for my changes to the ListView to be persisted only once the FormView saves (so if someone makes some changes to the ListView and then cancels out of the FormView, the changes are discarded). Along the same lines, I'd like to be able to create a new event, enter its details, and sign some people up for it, all at once; when the FormView saves, it gets the new ID for the event, and then the ListView saves using that ID.</p>
<p>In the past (pre-Linq) I've accomplished this with my own extensively customized FormView and SqlDataSource objects, which take care of temporarily persisting the data changes, getting the event ID from the FormView, etc. Is there a more standard way of dealing with this scenario using the LinqDataSource? </p>

272,987 | <p>We have a pretty mature COM dll, which we test using DUnit. One of our recent tests creates a few threads, and tests the object from those threads. This test works fine when running the test using the gui front-end, but hangs when running as a console application. Here's a quick pseudo view of what we have in the test</p>
<pre><code>SetupTest;
fThreadRefCount := 0; //number of active threads
Thread1 := TMyThread.Create(True);
Inc(fThreadRefCount);
Thread1.OnTerminate := HandleTerminate; //HandleOnTerminate decrements fThreadRefCount
Thread3 := TMyThread.Create(True);
Inc(fThreadRefCount);
Thread2.OnTerminate := HandleTerminate; //HandleOnTerminate decrements fThreadRefCount
Thread3 := TMyThread.Create(True);
Inc(fThreadRefCount);
Thread3.OnTerminate := HandleTerminate; //HandleOnTerminate decrements fThreadRefCount
Thread1.Resume;
Thread2.Resume;
Thread3.Resume;
while fThreadRefCount > 0 do
Application.ProcessMessages;
</code></pre>
<p>I have tried doing nothing in the OnExecute, so I'm sure it's not the actual code I'm testing. In the console, fThreadRefCount never decrements, while if I run it as a gui app, it's fine!</p>
<p>As far as I can see, the OnTerminate event is just not called.</p>

272,993 | <p>I have a rails template (.rhtml file) generating a Javascript object. It looks something like the following:</p>
<pre><code>var volumes = {
<% for volume in @volumes %>
<%= volume.id %> : <%= volume.data %>
<%= ',' unless volume === @volumes.last %>
<% end %>
};
</code></pre>
<p>Note the <code>unless</code> statement modifier to suppress printing the comma after the last element (to satisfy Internet Explorer, which incredibly doesn't support trailing commas in JSON properties declarations).</p>
<p>This appears to work, but as a matter of style, do people think it is reasonable to rely on <code><%= value unless condition %></code> in the template generating an appropriate <code>render</code> call?</p>

273,002 | <p>First of all, I will admit I am a novice to web services, although I'm familiar with HTML and basic web stuff. I created a quick-and-dirty web service using Python that calls a stored procedure in a MySQL database, that simply returns a BIGINT value. I want to return this value in the web service, and I want to generate a WSDL that I can give our web developers. I might add that the stored procedure only returns one value.</p>
<p>Here's some example code:</p>
<pre><code>#!/usr/bin/python
import SOAPpy
import MySQLdb
def getNEXTVAL():
cursor = db.cursor()
cursor.execute( "CALL my_stored_procedure()" ) # Returns a number
result=cursor.fetchall()
for record in result:
return record[0]
db=MySQLdb.connect(host="localhost", user="myuser", passwd="********", db="testing")
server = SOAPpy.SOAPServer(("10.1.22.29", 8080))
server.registerFunction(getNEXTVAL)
server.serve_forever()
</code></pre>
<p>I want to generate a WSDL that I can give to the web folks, and I'm wondering if it's possible to have SOAPpy just generate one for me. Is this possible?</p>

<blockquote>

<p>which would appear to be either a programming error on the part of the library, or a symptom of memory corruption. Is there any way to know the last line of Python source code it executed, given a core file? Or if it is attached in GDB? I realize it is probably all compiled bytecode, but I'm hoping there someone out there may have dealt with this. Currently it is running with the trace module active and we're hoping it will happen again, but it could be a long while.</p>

273,054 | <p>I'm building the HTML code within an XML DOM object to be used as the contents of the innerHTML of a div element using an XSL template. Traditionally we create a new XML DOM document and add the input parameters as XML Elements for the transform via javascript. This is all very time-consuming as we are basically hand picking the data from another XML document that represents our current account and copying the data into a transient XML DOM document. </p>
<p>What I'd like to do is clone the relevant node of the account document (i.e. customer info) and use it as the basis for the transform. I don't want to use the account document directly as I'd like to be able to add transform specific input, without making changes to the account object.</p>
<p>How efficient is using .cloneNode(true) for a desired node of about typically less than 200 elements from a document of typically 2000+ elements? The target platform is IE6 with no external tools (i.e. ActiveX).</p>

273,067 | <p>Sometimes, my UIWebView will have a grey box over part or all of the content. I can't make heads or tails of why it's happening. It happens regularly for certain content.</p>
<p>Thanks!</p>
<p>--Update--</p>
<p>It seems to occur when the webview is not immediately viewable on the screen -- ie i've got a scrollview, and the webview is below the fold.</p>
<p>--Update #2--</p>
<p>When I bring the content above the fold, it loads fine most of the time. There are still instances when the grey box is still showing up. The weird part is if i double-tap it, it finishes loading the content just fine. bizarre</p>
<p>--Update #3--</p>
<p>Okay, so it seems to be that if my uiwebview has a height greater than 1000px, a grey box appears on the rest of the content below 1000px. A double-tap reveals the actual content.</p>

273,081 | <p>I have an application that needs to hit the ActiveDirectory to get user permission/roles on startup of the app, and persist throughout. </p>
<p>I don't want to hit AD on every form to recheck the user's permissions, so I'd like the user's role and possibly other data on the logged-in user to be globally available on any form within the application, so I can properly hide functionality, buttons, etc. where necessary.</p>
<p>Something like:</p>
<pre><code>if (UserProperties.Role == Roles.Admin)
{
btnDelete.Visible = false;
}
</code></pre>
<p>What are the best practices for storing static user data in a windows app? Solutions such as a Singleton, or global variables may work, but I was trying to avoid these.</p>
<p>Is a User object that gets passed around to each form's contructor just as bad?</p>

273,103 | <p>I have a class that inherits from a base class and implements the following...</p>
<pre><code> Public Function CompareTo(ByVal obj As Object) As Integer Implements System.IComparable.CompareTo
</code></pre>
<p>Now the base class it inherits from also implements this System.IComparable.CompareTo so I'm getting the following compiler warning:</p>
<p><em>Warning: 'System.IComparable.CompareTo' is already implemented by the base class. Re-implementation of function assumed.</em> </p>
<p>I'm fine with that so my question is how can I suppress this warning for just this function (i.e. not all such warnings).</p>
<p><strong>Clarifications:</strong> </p>
<ul>
<li>Here is a <a href="http://msdn.microsoft.com/en-us/library/dwwt4s94(VS.80).aspx" rel="noreferrer">link</a> to the error on MSDN. </li>
<li>I've already tried both Shadows and Overrides and neither eliminates the warning. </li>
<li>The warning isn't on the method itself (unless Shadows or Overrides are omitted), but rather it's on "Implements System.IComparable.CompareTo" specifically.</li>
<li>I am not looking to suppress all warnings of this type (if they crop up), just this one.</li>
</ul>
<p><strong>Solution:</strong><br>
I was hoping to use the System.Diagnostics.CodeAnalysis.SuppressMessage attribute or something like C#'s #pragma but looks like there's no way to suppress the warning for a single line. There is a way to turn this message off for this project though, without turning <em>all</em> warnings off.</p>
<p>I manually edited the .vbproj file and included 42015 in the node for Debug and Release compilations. Not ideal but better than always seeing the warning in the IDE.</p>
<p>If someone has a better solution please add it and I'll gladly try it flag the answer.</p>

273,126 | <p>I am wondering how the HttpContext is maintained given that the request-response nature of the web is essentially stateless.</p>
<p>Is an identifier being for the HttpContext object being sent as part of the __EVENTTarget / __EVENTARGUMENTS hidden fields so that the HttpRuntime class can create the HttpContext class by reading this section from the request (HttpWorkerRequest)? I don't think</p>
<p>Please let me know as I am trying to fill some holes in my understanding of the http pipeline and I was unable to find any information about this.</p>
<p>I understand something like
HttpContext.Current.Session["myKey"] = Value;</p>
<p>just works but if I had to do something similar in a different language (say perl), I would have to use hidden fields for the same, wouldn't I?</p>
<p>Thanks

273,141 | <p>I haven't used regular expressions at all, so I'm having difficulty troubleshooting. I want the regex to match only when the contained string is all numbers; but with the two examples below it is matching a string that contains all numbers plus an equals sign like "1234=4321". I'm sure there's a way to change this behavior, but as I said, I've never really done much with regular expressions.</p>
<pre><code>string compare = "1234=4321";
Regex regex = new Regex(@"[\d]");
if (regex.IsMatch(compare))
{
//true
}
regex = new Regex("[0-9]");
if (regex.IsMatch(compare))
{
//true
}
</code></pre>
<p>In case it matters, I'm using C# and .NET2.0.</p>

273,142 | <p>I'm looking to patch a piece of abandonware with some code.</p>
<p>The software is carbon based, so I can not use an InputManager (at least, I do not think I can). My idea was to add a dylib reference to the mach-o header, and launch a new thread when the initialization routine is called.</p>
<p>I have mucked around with the mach-o header using a hexeditor to add the appropriate load command (LC_ LOAD_DYLIB). </p>
<p>otool reports what I expect to see, so I'm fairly confident that the file is correctly formatted.</p>
<pre>
Load command 63
cmd LC_LOAD_DYLIB
cmdsize 60
name @executable_path/libAltInput.dylib (offset 24)
time stamp 1183743291 Fri Jul 6 19:34:51 2007
current version 0.0.0
compatibility version 0.0.0
</pre>
<p>However, launching the binary gives me the following error</p>
<pre>
dyld: bad external relocation length
</pre>
<p>All I can guess this means is that I need to modify the LC_ SYMTAB or LC_ DYNSYMTAB sections...</p>
<p>Anyone have any ideas?</p>

273,148 | <p>Has anyone tried using these new VS2008 MFC classes yet? I can't seem to find any examples anywhere. Even the VS2008 samples(1) don't mention these classes. (They use CToolTip.)</p>
<p><em>(1) Update: My mistake. I had downloaded the <a href="http://www.microsoft.com/downloads/details.aspx?FamilyId=01AE159F-08CD-495B-8BF4-A48CC395AD7B&displaylang=en" rel="nofollow noreferrer">non-SP1 samples</a>. I see that the <a href="http://www.microsoft.com/downloads/details.aspx?FamilyID=9761bb57-f066-4b70-9318-3965c5e68aad&DisplayLang=en" rel="nofollow noreferrer">SP1 samples</a> have samples specifically for the 2008 Feature Pack, including the DlgToolTips and ToolTipDemo projects mentioned in an answer. Unfortunately, they don't address doc/view or CTooltipManager.</em></p>
<p>Specifically, I'm trying to display tooltips in a standard MFC view/document application where there are two side-by-side views whose parent is CSplitterWnd. I had this working pre-SP1, and I thought this'd be a good time to try the new Feature Pack tooltip classes.</p>
<p>Is there any way to make these things work without overriding PreTranslateMessage() and manually calling RelayEvent()? (I don't think I've seen anything in MFC as poorly designed as tooltips.)</p>
<p>It doesn't seem as simple as merely calling CTooltipManager::CreateToolTip() and then AddTool() on the created tip.</p>

273,151 | <p>I've used MS Word automation to save a .doc to a .htm. If there are bullet characters in the .doc file, they are saved fine to the .htm, but when I try to read the .htm file into a string (so I can subsequently send to a database for ultimate storage as a string, not a blob), the bullets are converted to question marks or other characters depending on the encoding used to load into a string.</p>
<p>I'm using this to read the text:</p>
<pre><code>string html = File.ReadAllText(myFileSpec);
</code></pre>
<p>I've also tried using StreamReader, but get the same results (maybe it's used internally by File.ReadAllText).</p>
<p>I've also tried specifying every type of Encoding in the second overload of File.ReadAllText:</p>
<pre><code>string html = File.ReadAllText(originalFile, Encoding.ASCII);
</code></pre>
<p>I've tried all the available enums for the Encoding type.</p>
<p>Any ideas?</p>

273,169 | <p>How can I dynamically invoke a class method in PHP? The class method is not static. It appears that </p>
<pre><code>call_user_func(...)
</code></pre>
<p>only works with static functions?</p>

273,199 | <p>I'm trying to convert some Xaml to HTML using the .NET XslCompiledTransform and am running into difficulties getting the xslt to match Xaml tags. For instance with this Xaml input:</p>
<pre><code><FlowDocument PagePadding="5,0,5,0" AllowDrop="True" NumberSubstitution.CultureSource="User" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation">
<Paragraph>a</Paragraph>
</FlowDocument>
</code></pre>
<p>And this xslt:</p>
<pre><code><?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:msxsl="urn:schemas-microsoft-com:xslt" exclude-result-prefixes="msxsl"
>
<xsl:output method="html" indent="yes"/>
<xsl:template match="/">
<html>
<body>
<xsl:apply-templates />
</body>
</html>
</xsl:template>
<xsl:template match="FlowDocument">
<xsl:apply-templates />
</xsl:template>
<xsl:template match="Paragraph" >
<p>
<xsl:apply-templates />
</p>
</xsl:template>
</code></pre>
<p>I get this output:</p>
<pre><code><html>
<body>
a
</body>
</html>
</code></pre>
<p>Rather than the expected:</p>
<pre><code><html>
<body>
<p>a</p>
</body>
</html>
</code></pre>
<p>Could this be a problem with the namespace? This is my first attempt at an xsl transform, so I'm at a loss.</p>

273,203 | <p>I'm using python\pyodbc and would like to access the second result set of a stored procedure. As near as I can tell, pyodbc does not support multiple result sets. Additionally, I can't modify the stored procedure. Are there any options to access the second result set using SQL or some other work-around? Perhaps create a second stored procedure that only returns the second result set of the first?</p>

273,209 | <p>Is it ever acceptable to have a <a href="http://en.wikipedia.org/wiki/Memory_leak" rel="noreferrer">memory leak</a> in your C or C++ application?</p>
<p>What if you allocate some memory and use it until the very last line of code in your application (for example, a global object's destructor)? As long as the memory consumption doesn't grow over time, is it OK to trust the OS to free your memory for you when your application terminates (on Windows, Mac, and Linux)? Would you even consider this a real memory leak if the memory was being used continuously until it was freed by the OS.</p>
<p>What if a third party library forced this situation on you? Would refuse to use that third party library no matter how great it otherwise might be?</p>
<p>I only see one practical disadvantage, and that is that these benign leaks will show up with memory leak detection tools as false positives.</p>

273,217 | <p>Does anybody know what's going on here:</p>
<p>I run hibernate 3.2.6 against a PostgreSQL 8.3 (installed via fink) database on my Mac OS X. The setup works fine when I use Java 6 and the JDBC 4 driver (postgresql-8.3-603.jdbc4). However, I need this stuff to work with Java 5 and (hence) JDBC 3 (postgresql-8.3-603.jdbc3). When I change the jar in the classpath and switch to Java 5 (I do this in eclipse), I get the following error:</p>
<pre><code>Exception in thread "main" org.hibernate.exception.JDBCConnectionException: Cannot open connection
at org.hibernate.exception.SQLStateConverter.convert(SQLStateConverter.java:74)
<Rows clipped for readability>
Caused by: java.sql.SQLException: No suitable driver
at java.sql.DriverManager.getConnection(DriverManager.java:545)
at java.sql.DriverManager.getConnection(DriverManager.java:140)
at org.hibernate.connection.DriverManagerConnectionProvider.getConnection(DriverManagerConnectionProvider.java:110)
at org.hibernate.jdbc.ConnectionManager.openConnection(ConnectionManager.java:423)
</code></pre>
<p>What's the problem here? I cannot see it. Here is my hibernate configuration:</p>
<pre><code><hibernate-configuration>
<session-factory>
<property name="connection.url">jdbc:postgresql:test</property>
<property name="connection.username">postgres</property>
<property name="connection.password">p</property>
<property name="connection.pool_size">1</property>
<property name="dialect">org.hibernate.dialect.PostgreSQLDialect</property>
<property name="current_session_context_class">thread</property>
<property name="show_sql">true</property>
<mapping resource="com/mydomain/MyClass.hbm.xml"/>
</session-factory>
</hibernate-configuration>
</code></pre>
<p><strong>EDIT:</strong> The longer, more usual form of the connection URL: <em>jdbc:postgresql://localhost/test</em> has the exact same behaviour.</p>
<p>The driver jar is definitely in the classpath, and I also do not manage to get any errors with this direct JDBC test code:</p>
<pre><code>public static void main(String[] args) throws Exception {
Class.forName("org.postgresql.Driver");
Connection con=DriverManager.getConnection("jdbc:postgresql://localhost/test","postgres", "p");
}
</code></pre>

273,261 | <p>I have an application where I accept a socket connection from a telnet client and put up a simple, keyboard driven character GUI.</p>
<p>The telnet client, at least on Linux, defaults into line-at-a-time mode, so I always have to do <code>^]mode char</code> manually.</p>
<p>A skim of the relevant RFCs suggests that if my application simply sent the characters <code>IAC DONT LINEMODE (\377\376\042)</code> as soon as the client connects, the client should be forced into character mode. However, it doesn't make any difference.</p>
<p>What's the simplest bit of code that would do the job? Ideally just a string to be sent. My application can absorb whatever junk the client sends back.</p>

273,273 | <p>I'm looking for a small and fast library implementing an HTTP server in .NET</p>
<p>My general requirements are:</p>
<ul>
<li>Supports multiple simultaneous connections</li>
<li>Only needs to support static content (no server side processing)</li>
<li>HTTP only, HTTPS not needed</li>
<li>Preferably be able to serve a page from an in memory source. I want to integrate it into another app to be able to make changing data available via a browser, but I don't want to have to write it to a file on disk first. For example, just pass it a C# string to use as the current page content.</li>
<li>Preferably open source so I can modify it if needed</li>
<li><em>Definitely</em> needs to be free... it's for a personal project with no budget other than my own time. I also want to be able to release the final product that would use this library freely (even if that means complying to the particular OSS license of that library.</li>
</ul>
<p>Edit: To clarify some more, what I need can be REALLY simple. I need to be able to serve essentially 2 documents, which I would like to be served directly from memory. And that's it. Yes, I could write my own, but I wanted to make sure I wasn't doing something that was already available.</p>

273,275 | <p>Rails has an awesome way of looking up column names and expected datatypes from the DB, alleviating a lot of programming.</p>
<p>I'm trying to build something like this in C#.NET, because we have large tables that are ever changing. I'll be adding parameters like so:</p>
<pre><code>SqlParameter param = new SqlParameter("parametername", *SqlDbType.Int*);
param.Direction = ParameterDirection.Input;
param.Value = 0;
comm.Parameters.Add(param);
</code></pre>
<p>Notice the SqlDbType. How can I get that? If I get DataColumns from the DataSet, all I can get is System types like System.string.</p>

273,283 | <p>I just added printing capability to a web site using a style sheet (ie. @media print, etc.) and was wondering if I could use a similar method for adding support for mobile devices.</p>
<p>If not, how do I detect a mobile device? My pages are C# (.aspx) and I'd like to scale back the pages for ease of use on a mobile device.</p>
<p>Any advice for me?</p>
<p>EDIT: My wife has a BlackBerry, so at a miminum I'd like to enable our company's web site for that.</p>

273,297 | <p>Few of us would deny the awesomeness of debuggers, but to make it more useful, some tricks can be used. </p>
<p>For example in Python, you can use <strong><em>pass</em></strong> to do absolutely nothing except to leave you room to put a break point and allow you to observe the values in the Watch window. </p>
<p>In C#, I used to do <strong><em>GC.Collect()</em></strong>, but now I use <strong><em>if (false){}</em></strong></p>
<p>What's your most playful dummy line?</p>

273,307 | <p>I've got a very small standalone vb.net app that gets run automatically. Every now and then it hits an error condition that I want to log and then keep processing. But, this is far too minor a thing to store in the system's main log - I really just want to append a line to a text file.</p>
<p>What's the least stress way to append a line of text to a file (and have it create the file if it's not there) under .net?</p>
