289,434 | <p>I'm making a Java application with an application-logic-thread and a database-access-thread.
Both of them persist for the entire lifetime of the application and both need to be running at the same time (one talks to the server, one talks to the user; when the app is fully started, I need <em>both</em> of them to work).</p>
<p>However, on startup, I need to make sure that initially the app thread waits until the db thread is ready (currently determined by polling a custom method <code>dbthread.isReady()</code>).
I wouldn't mind if app thread blocks until the db thread was ready.</p>
<p><code>Thread.join()</code> doesn't look like a solution - the db thread only exits at app shutdown.</p>
<p><code>while (!dbthread.isReady()) {}</code> kind of works, but the empty loop consumes a lot of processor cycles.</p>
<p>Any other ideas? Thanks.</p>

289,438 | <p>My company is currently migrating some of their really old db's to sql server 2005. Some legacy apps have problems connecting to the new server. The connection string works in Asp.NET 2.0, probably because it assumes tcp:1433 automatically.</p>
<p>I have to construct the connection string like this in ASP.NET 1.1 for it to work:</p>
<pre><code>"Server=tcp:my.server.com,1433;..."
</code></pre>
<p>Without the protocol and the port, the connection fails ("Invalid Connection exception")</p>
<p>TCP 1433 and UDP 1434 are open on our firewall. On SQL Server 2005 Remote Access is enabled, so is TCPIP, the SQL Browser service is running, I use the proper login credentials.</p>
<p>Any ideas why I can't just specify the server name without protocol and port number?</p>

289,440 | <p>I have a quite big XML output from an application. I need to process it with my program and then feed it back to the original program. There are pieces in this XML which needs to be filled out our replaced. The interesting part looks like this:</p>
<pre><code><sys:customtag sys:sid="1" sys:type="Processtart" />
<sys:tag>value</sys:tag>
here are some other tags
<sys:tag>value</sys.tag>
<sys:customtag sys:sid="1" sys:type="Procesend" />
</code></pre>
<p>and the document contains several pieces like this.</p>
<p>I need to get all XML pieces inside these tags to be able to make modifications on it. I wrote a regular expression to get those pieces but it does not work:</p>
<pre><code>XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(@"output.xml");
Regex regExp = new Regex(@"<sys:customtag(.*?)Processtart(.*?)/>(.*?)<sys:customtag (.*?)Procesend(.*?)/>", RegexOptions.Multiline & RegexOptions.IgnorePatternWhitespace & RegexOptions.CultureInvariant);
MatchCollection matches = regExp.Matches(xmlDoc.InnerXml);
</code></pre>
<p>If I leave the whole stuff in one line and call this regexp without the multiline option, it does find every occurences. By leaving the file as it is and set the multiline option, it does not work. What is the problem, what should I change? Or is there any easier way to get the XML parts between these tags without regexp?</p>

289,441 | <p>Is it possible to set some image as title of Navigation bar?</p>
<p>I think NYTimes application used a Navigation bar and title is look like image file (the reason why it's seems <code>UINavigationBar</code> is because they use right button to search).</p>

289,443 | <p>We have a custom project management tool built in ASP,net 3.5 and we use VisualSVN for our version management. However, we are looking a way to report the version changes through the project management tool by integrating VisualSVN with our project management tool, i.e. pretty much similar to what Trac [python based SCM tool] provides. </p>
<p>Basically looking for a simple VisualSVN Client API to be able to detect & report the file changes based on the revision set provided.</p>

289,468 | <p>I am working on an algorithm that will try to pick out, given an HTML file, what it thinks is the parent element that most likely contains the majority of the page's content text.
For example, it would pick the div "content" in the following HTML:</p>
<pre><code><html>
<body>
<div id="header">This is the header we don't care about</div>
<div id="content">This is the <b>Main Page</b> content. it is the
longest block of text in this document and should be chosen as
most likely being the important page content.</div>
</body>
</html>
</code></pre>
<p>I have come up with a few ideas, such as traversing the HTML document tree to its leaves, adding up the length of the text, and only seeing what other text the parent has if the parent gives us more content than the children do.</p>
<p>Has anyone ever tried something like this, or know of an algorithm that can be applied? It doesn't have to be solid, but as long as it can guess a container that contains most of the page content text (for articles or blog posts, for example), that would be awesome.</p>

289,472 | <p>I just uploaded my first ASP.NET (as part of my learning of vb.net) and got into awful mess with the connection pooling (funny things happen when there are more than 1 user of your web site) all sorted now by better use of the try catch statements (well the idea was to learn) BUT I was wondering if this is the best / final method, now if the try fails, then a LOT of the detail on the page isn't placed/updated, so if you are doing some database work and the try fails, do you reload the page ... redirect to self and hope it work the next time ... or just inform the user there was a error and they should try again ?</p>
<p>Thanks</p>

289,475 | <p>I mean what the most efficient way to get information about the quantity of your page's items and make sql query with LIMIT that you need. or I should get all items and then crop array with php functions?</p>
<p>now I do 2 queries: first to count all items and second to get items that I need with LIMIT. </p>
<p>OK, I'll be more concrete. For example I need to show a question on my page and 20 answers to this question. At the bottom there shold be page control: links to the next, prev page and so on. I want to show proper number of links (number of answers/20) and when I go to any link I want to recieve proper answers (for example 41 to 60 on the 3d page). So what's the best way to get number of items (answers) to show proper number of links and to get proper answers for each link?</p>

289,483 | <p>I have two machines setup to run Visual Studio 2008 (SP1) & NET Framework 3.5 (SP1). If I create a .tt file in a console appliaction on machine #1 it automatically creates the sub .cs file for me, however if I do the exact same on machine #2 then no sub .cs file is created.</p>
<p>I have tried toggling the "Show All Files" option, restarting visual studio (multiple times), added new <code>.tt</code> files (with the same outcome), tried it in both a C# and a VB.NET project and Google is drawing up blanks. </p>
<p>Is it possible for T4 text templates to have been disabled somehow? If so, then how the heck do I turn them back on, it's annoying :-).?</p>

289,512 | <p>I can't figure out how to define the default constructor (when it exists overloads) for a type in StructureMap (version 2.5) by code.</p>
<p>I want to get an instance of a service and the container has to inject a Linq2Sql data context instance into it.</p>
<p>I wrote this in my 'bootstrapper' method :</p>
<pre><code>ForRequestedType<MyDataContext>().TheDefault.Is.OfConcreteType<MyDataContext>();
</code></pre>
<p>When I run my app, I got this error :</p>
<blockquote>
<p>StructureMap Exception Code: 202<br>
No Default Instance defined for PluginFamily MyNamespace.Data.SqlRepository.MyDataContext, MyNamespace.Data, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null</p>
</blockquote>
<p>If I comment out all Linq2Sql generated contructors that I don't need, it works fine.</p>
<p>Update : Oh, and I forgot to say that I would not use the <code>[StructureMap.DefaultConstructor]</code> attribute.</p>

289,529 | <p>I am new to decoding techniques and have just learnt about base64, sha-1, md5 and a few others yesterday. </p>
<p>I have been trying to figure out what "orkut" worms actually contain. </p>
<p>I was attacked by many orkut spammers and hackers in the past few days, and there is a similarity in the URLs that they send to us. </p>
<p>I don't know what information it contains but I need to figure it out. </p>
<p>The problem lies in the following texts:</p>
<pre><code>Foo+bZGMiDsstRKVgpjhlfxMVpM=
lmKpr4+L6caaXii9iokloJ1A4xQ=
</code></pre>
<p>The encoding above appears to be base64 but it is not, because whenever I try to decode it using online base64 decoders, I get raw output and it doesn't decode accurately. </p>
<p>Maybe some other code has been mixed with base64. </p>
<p>Can anyone please help me to decode it?</p>

289,559 | <p>The C++ standard dictates that member variables inside a single access section must be layed out in memory in the same order they were declared in. At the same time, compilers are free to choose the mutual ordering of the access sections themselves. This freedom makes it impossible in theory to link binaries created by different compilers. So what are the remaining reasons for the strict in-section ordering? And does the <s>upcoming C++09</s> new C++11 standard provide a way to fully determine object layouts "by hand"?</p>

289,568 | <p>The C++ standard imposes an ordering on class member variables in memory. It says that the addresses of member variables have to increase in the order of declaration, but only inside one access section. Very specifically, this does not seem to prevent compilers from laying out access sections in an interleaved way. For example:</p>
<pre><code>class X {
public:
int i;
int j;
private:
int k;
int n;
}
</code></pre>
<p>Does the standard allow compilers to lay out the data members in the order i, k, j, n? This would give compilers some (limited) freedom in optimizing object layout without violating the standard.</p>

289,572 | <p>Is there a USB HID pen driver in Windows Vista?
If so, what are the requirements for USB descriptors, in order to make Windows Vista recognize the pen and load the pen driver?</p>
<p>What I'm searching for is the pen equivalent to the HID mouse driver, HID keyboard driver and mass storage driver. The mentioned example drivers makes it possible for Windows, Linux and Mac OS to recognize mouse, keyboard and memory sticks without installing new drivers.</p>
<p>Windows Vista has a lot of native support for pen, and it is possible to define a USB pen device only using standard HID usage tables (from a USB protocol point of view). So far I'm able to make USB HID descriptors that qualify as mouse and keyboard (from OS point of view), and automatically uses the standard driver supplied by the OS. </p>
<p>For my Pen, however, Windows Vista just loads the generic HID driver, and does not realize that the device is a "pen". The motivation for defining a pen rather than a mouse with absolute coordinates, is that Vista supports special features like "gestures", but this is only enabled for Pen/Digitizer devices.</p>

289,578 | <p>Recently when I looked into iPhone memory management, I tried to compare the convenience method and init method on the same object. For example, I have UIImageView where it displays a downloaded NSData:</p>
<p>Convenience method:</p>
<pre><code>imageView.image = [UIImage imageWithData:[downloads dataAtIndex:0]];
</code></pre>
<p>init method:</p>
<pre><code>UIImage *aImage = [[UIImage alloc] initWithData:[downloads dataAtIndex:0]];
imageView.image = aImage;
[aImage release];
</code></pre>
<p>When I try to go back and forth on the views to increase the memory usage and hit "Simulate Memory Warning", the memory usage for the app went from 20MB to 18MB with convenience method, and init method went from 20MB to 13MB immediately.</p>
<p>I also waited and interacted with the app to give time on releasing on the convenience method's autorelease. But it didn't drop much.</p>
<p>Other than the autorelease vs release, what else contributed the difference?</p>

289,601 | <p><strong>Sorry answer found while typing</strong> </p>
<p>I am trying to connect to an external webservice that requires username/password authentication through a proxy. I am using Visual Studio Express 2008 to generate a service reference</p>
<ul>
<li>I have connected to the same
webservice using a web reference.We
only had to set a larger timeout
because it takes a long time to
finish. </li>
<li>I have connected to another
webservice that does not require
username/password authentication
with a generated service reference
and some settings to get it through
the proxy. </li>
</ul>
<p>So my thought would be to
take this reference, point it to the
correct webservice and add
authentication.</p>
<p>The config I am using without security:</p>
<pre><code> <?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.net>
<defaultProxy useDefaultCredentials="true">
<proxy bypassonlocal="False" proxyaddress="http://***.***.****:80" />
</defaultProxy>
</system.net>
<system.serviceModel>
<bindings>
<customBinding>
<binding name="AreaWebServiceSoap12">
<textMessageEncoding maxReadPoolSize="64" maxWritePoolSize="16"
messageVersion="Soap12" writeEncoding="utf-8">
<readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"
maxBytesPerRead="4096" maxNameTableCharCount="16384" />
</textMessageEncoding>
<httpTransport manualAddressing="false" maxBufferPoolSize="524288"
maxReceivedMessageSize="65536" allowCookies="false" authenticationScheme="Anonymous"
bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
keepAliveEnabled="true" maxBufferSize="65536" proxyAuthenticationScheme="Anonymous"
realm="" transferMode="Buffered" unsafeConnectionNtlmAuthentication="false"
useDefaultWebProxy="true" />
</binding>
</customBinding>
</bindings>
<client>
<endpoint address="http://www.****.*****.****.com/samplewebservice/service.asmx"
binding="customBinding" bindingConfiguration="AreaWebServiceSoap12"
contract="ServiceReference1.ServiceSoap" name="ServiceSoap" />
</client>
</system.serviceModel>
</configuration>
</code></pre>
<p>I have added te following code to my call for authentication:</p>
<pre><code>static void Main(string[] args)
{
ServiceSoapClient s = new ServiceSoapClient();
s.ClientCredentials.UserName.UserName = @"username";
s.ClientCredentials.UserName.Password = @"password";
Service.RawGpsData[] result = s.GetRawGpsData(0);
Console.WriteLine(String.Format("done:{0}",result.Length));
Console.ReadLine();
}
</code></pre>
<p>Just using this setup gives an error as expected:</p>
<p><em>The HTTP request is not authorized with client authentication scheme Anonymous. The authentication header from the server is received, is NTLM.</em></p>
<p>Now I get lost and start trying silly things because I am just starting to use WCF.</p>
<p>When I add the following section to the config</p>
<pre><code> <security authenticationMode="UserNameOverTransport"></security>
</code></pre>
<p>I get the following error:</p>
<p><em>The binding CustomBinding.http: / / tempuri.org / for the contract AreaWebServiceSoap.AreaWebServices is configured with a verification mode for which a transport level with integrity and confidentiality is required. The transport can not provide integrity and confidentiality.</em></p>
<p>Sorry, while typing this question I stumbled upon the answer myself. I still think people might be interested in this and all comments and thoughts are still welcome. So I will leave the question here and make it community and post the answer myself.</p>

289,622 | <p>Now that I've finnaly moved to doing some development/support work for Windows 2008 I find myself annoyed by the lack of one feature I just can't enable: the desktop shortcut to "My Computer" I've grown used to. I know how to enable this on XP and 2003, but I just can't find the setting on 2008.</p>
<p>How can a user configure which desktop icons (My Computer, My Documents, Recycling Bin etc) on Windows 2008 Server?</p>

289,649 | <p>I'm trying to reorder/group a set of results using SQL. I have a few fields (which for the example have been renamed to something a bit less specific), and each logical group of records has a field which remains constant - the address field. There are also fields which are present for each address, these are the same for every address.</p>
<pre><code>id forename surname address
1 John These Address1
2 Lucy Values Address1
3 Jenny Are Address1
4 John All Address2
5 Lucy Totally Address2
6 Jenny Different Address2
7 Steve And Address2
8 Richard Blah Address2
address John Lucy Jenny Steve Richard
Address1 These Values Are (null) (null)
Address2 All Totally Different And Blah
</code></pre>
<p>For example: John,Lucy,Jenny,Steve and Richard are the only possible names at each address. I know this because it's stored in another location.</p>
<p>Can I select values from the actual records in the left hand image, and return them as a result set like the one on the right? I'm using MySQL if that makes a difference.</p>

289,665 | <p>I'm an avid vim user and have started to write some SQL code recently. I like to write my SQL statements in CAPS and sometimes forget to switch <kbd>CapsLock</kbd> 'off' and I then quickly wreak havoc on my code before I realise what's happening.</p>
<p>I have so far not found any way to tell whether the <kbd>CapsLock</kbd> key is on other than looking at my keyboard (which requires me to look away from the screen which I consider a big delay). </p>
<p>Ideally I would like vim to automatically change my background colour whenever <kbd>CapsLock</kbd> is 'on' but I'd be willing to settle for some other on-screen indicator of <kbd>CapsLock</kbd> status as a compromise.</p>

289,672 | <p>Delphi object inspector doesn't show TFrame descendants's additional properties by design.
People tend to suggest using a known trick which is commonly used for showing TForm descendant's properties on the Object inspector. The trick is: registering custom module for TForm descendants to Delphi IDE via design time package like:</p>
<pre><code>RegisterCustomModule(TMyFrame, TCustomModule);
</code></pre>
<p>The object inspector can show additional properties of the TFrame Descendant's instance with this way but it loses its frame behaviours while it is embedded in a form. Not redesignable, not possible to implement events for its subcomponents and it accepts child controls (which it musn't). But it behaves normally in its own design area.</p>
<p>Looks like, those behaviours provided by Delphi IDE specially just for TFrame. They problaly are not kind of generic facilities. </p>
<p>Is there any other way to accomplish this without losing frame behaviours ?</p>
<p>I'm using Delphi 2007</p>

289,681 | <p>I'm trying to use the < C-a> (<kbd>CTRL</kbd>+<kbd>A</kbd>) shorcut under vim to increment a variable under the cursor. This works fine under vim running on Linux. However when I try to do this in gvim under windows it "selects all" (i.e. highlights or visually selects all text in the current window). How can I change this behaviour or alternatively how can I recover the increment variable functionality (e.g. perhaps with a different key mapping)?</p>

289,688 | <p>I have hit a classic problem of needing to do a string replace on a text field in an sql 2000 database. This could either be an update over a whole column or a single field I'm not fussy.</p>
<p>I have found a few examples of how to use updatetext to achieve it but they tend to be in stored procedures, does anyone know of a similar thing that is wrapped into a function so I can use it like I would usually use Replace(). The problem with the Replace() function for anyone who isn't aware is that it doesn't support text fields.</p>
<p>Edit: I realised I could probably get away with varchar(8000) so have swapped the fields to this type which fixes the issue. I never found a true solution.</p>

289,702 | <p>I am writing unit tests for a class, which has a static final variable.
However, since the state of the static final var is modified in each test, I need some way to reinitialize it.</p>
<p>
How would this be possible? Would i need to use some sort of a custom classloader? </p>
<p>
The variable is initialized as -
<pre>
static final CountdownLatch latch = new CountdownLatch(1);

289,712 | <p>As a long time Pascal and Delphi developer, I always line up my begin and ends thus :</p>

<p>What drives me nuts is code formatted thus :</p>
<pre><code>begin
if x = y then begin
...
...
end
else
for i := 0 to 20 do begin
...
...
end;
end;
</code></pre>
<p>When there are a few levels of compound statements I find this hard to read. The above code is ok, because it's not that complicated, but for consistency I'd prefer all begins and ends aligned.</p>
<p>As I start using c#, I find myself aligning curly brackets too. What's the norm in the C# world? </p>
<p><strong>Edit :</strong></p>
<p>Someone has pointed out that this is the type of question that shouldn't be asked on SO. I don't see why not. I'm in the process of setting up a coding guidelines document. I know I'll get some resistance to certain things, I'm hoping to get a few answers here, so I can be ready to meet that resistance head-on.</p>

289,715 | <p>I am looking for the highest key value (a defined by the comparison operator) of a std::map.</p>
<p>Is this guaranteed to be </p>

<p>(I am a bit shaky on reverse iterators, and how much freedom there is in the implementation of std::map) </p>

289,727 | <p>Since MySQL doesn't seem to have any 'boolean' data type, which data type do you 'abuse' for storing true/false information in MySQL?</p>
<p>Especially in the context of writing and reading from/to a PHP script.</p>
<p>Over time I have used and seen several approaches:</p>
<ul>
<li>tinyint, varchar fields containing the values 0/1,</li>
<li>varchar fields containing the strings '0'/'1' or 'true'/'false'</li>
<li>and finally enum Fields containing the two options 'true'/'false'.</li>
</ul>
<p>None of the above seems optimal. I tend to prefer the tinyint 0/1 variant, since automatic type conversion in PHP gives me boolean values rather simply.</p>
<p>So which data type do you use? Is there a type designed for boolean values which I have overlooked? Do you see any advantages/disadvantages by using one type or another?</p>

289,729 | <p>I'm just starting to try out phpunit on some existing code. The naming convention we use is that the MyClass class should be in MyClass.class.php. PHPUnit seems to require that the file should be called MyClass.php. </p>

Could not find class "MyClass.class" in "/home/jd/skeleton/classes/MyClass.class.php".

289,743 | <p>Our coding standards ask that we minimise the use of C# var (suggests limiting it's use to being in conjunction with Linq). However there are times when using generics where it's reasonably convenient e.g.</p>
<pre><code>Dictionary<DateTime, Dictionary<string, float>> allValues = ...
// ...
foreach (var dateEntry in allValue)
</code></pre>
<p>is easier to type </p>
<pre><code>foreach (KeyValue<DateTime, Dictionary<string, float>> dateEntry in allValue)
</code></pre>
<p>(and easier than remembering what the explicit type is in some cases). </p>
<p>Do any of the refactoring tools have the ability to convert the former to the latter. I've had a look at Resharper but it doesn't seem to do (indeed it's default suggestion is to go in the opposite direction).</p>

289,770 | <p>In the past I've always gone and called my namespace for a particular project the same as the project (and principle class) e.g.:</p>
<pre><code>namespace KeepAlive
{
public partial class KeepAlive : ServiceBase
{...
</code></pre>
<p>Then from other projects whenever i've called that class its always been:</p>
<pre><code>KeepAlive.KeepAlive()...
</code></pre>
<p>I'm now beginning to think that this might not be such a good idea, but I'm sort of stumped what to actually call my namespace. What do other people do? Do you just have one namespace for all your projects?</p>

289,773 | <p>I use the app.config file to store some values (path to a mapping database, data connection selections). These settings differ on the user machines and I would like the installer to set them right. Is there an installer that can work with .NET config files during setup and allow me to create some dialogs that would help me fill in these values ?</p>
<p>I know this question may be similar to : <a href="https://stackoverflow.com/questions/75546/initializing-userconfig-or-appexeconfig-during-install">Initializing user.config or app.exe.config during install</a>, but I am not limited to VS 2008 setup project and I want to change the settings in the config files.</p>
<p>EDIT: I see that using WIX is one option, but I feel like cracking a walnut with a sledgehammer. It may be the only solution, but I still hope for something simple.</p>

289,779 | <p>I am working on a project where I need to create a boundary around a group of rectangles.</p>
<p>Let's use this picture as an example of what I want to accomplish.</p>
<p>EDIT: Couldn't get the image tag to work properly, so here is the full link:
<a href="http://www.flickr.com/photos/21093416@N04/3029621742/" rel="nofollow noreferrer">http://www.flickr.com/photos/21093416@N04/3029621742/</a> </p>
<p>We have rectangles A and C who are linked by a special link rectangle B. You could think of this as two nodes in a graph (A,C) and the edge between them (B). That means the rectangles have pointers to each other in the following manner: A->B, A<-B->C, C->B</p>
<p>Each rectangle has four vertices stored in an array where index 0 is bottom left, and index 3 is bottom right.</p>
<p>I want to "traverse" this linked structure and calculate the vertices making up the boundary (red line) around it. I already have some small ideas around how to accomplish this, but want to know if some of you more mathematically inclined have some neat tricks up your sleeves.</p>
<p>The reason I post this here is just that someone might have solved a similar problem before, and have some ideas I could use. I don't expect anyone to sit down and think this through long and hard. I'm going to work on a solution in parallell as I wait for answers.</p>
<p>Any input is greatly appreciated.</p>

289,794 | <p>I have an arraylist that contains items called Room. Each Room has a roomtype such as kitchen, reception etc.
I want to check the arraylist to see if any rooms of that type exist before adding it to the list.
Can anyone recommend a neat way of doing this without the need for multiple foreach loops?</p>
<p>(.NET 2.0)</p>
<hr>
<p>I havent got access to the linq technology as am running on .net 2.0. I should have stated that in the question.
Apologies</p>

289,804 | <p>I've written a program that counts lines, words, and characters in a text: it does this with threads. It works great sometimes, but not so great other times. What ends up happening is the variables pointing to the number of words and characters counted sometimes come up short and sometimes don't.</p>
<p>It seems to me that the threads are sometimes ending before they can count all the words or characters that they want to. Is it because these threads go out of scope when the while (true) loop breaks?</p>
<p>I've included the code from the thready part of my problem below:</p>
<pre><code>private void countText() {
try {
reader = new BufferedReader(new FileReader("this.txt"));
while (true) {
final String line = reader.readLine();
if(line == null) {break;}
lines++;
new Thread(new Runnable() {public void run() {chars += characterCounter(line);}}).start();
new Thread(new Runnable() {public void run() {words += wordCounter(line);}}).start();
println(line);
}
} catch(IOException ex) {return;}
}
</code></pre>
<p>(Sub Question: This is the first time I've asked about something and posted code. I don't want to use StackOverflow in place of google and wikipedia and am worried that this isn't an appropriate question? I tried to make the question more general so that I'm not just asking for help with my code... but, is there another website where this kind of question might be more appropriate?)</p>

289,812 | <p>What is the best approach to play a sequence of flv video files in Flash (with actionscript)? My goal is to have the transitions occur as smoothly as possible.</p>
<p>Currently i'm using the netStream class and capturing the onStatus events to play the next video when the current video has reached it's end duration. Althought this approach works fine, there is still a small gap between the ending of the current video and start of the next. Any ideas on how to optimize this method? </p>
<p>Thanks in advance :) </p>

<p>Our sites are fairly large in size, with a few hundred pages/views/controls/etc. however the time taken seems excessive in the 10-15 minute range (for reference, this is longer than it takes the entire solution with approx 40 projects to compile, and we're only pre-compiling two website projects).</p>
<p>I doubt that hardware is the issue as I'm running on the latest Quad core Intel chip, with 4GB RAM and a WD Velociraptor 10,000rpm hard disk. And part of what's odd is that the EXE doesn't seem to be using much CPU (1-5%) and doesn't seem to be doing an awful lot of I/O either.</p>
<p>So... is this a known issue? Why is it so slow? And is there any way to speed it up?</p>
<p><strong>Note:</strong> To clarify a couple of things people have answered about, I am not talking about the compilation of code within Visual Studio. We're using web application projects already, and the speed of compilation of those is not the issue. The problem is the pre-compilation of the site <em>after</em> these projects have already been compiled (<a href="http://msdn.microsoft.com/en-us/library/ms229863.aspx" rel="noreferrer">see this MSDN page for more details</a>) as part of the dev build script. We are performing in-place pre-compilation, not copying the files to a target directory.</p>

289,841 | <p>In OOP languages like C# or VB.NET, if I make the properties or methods in a super class <code>protected</code> I can't access them in my Form - they can only be accessed in my class that inherits from that super class.</p>
<p>To access those properties or methods I need to make them <code>public</code>, which defeats encapsulation, or re-write them into my class, which defeats inheritance.</p>
<p>What is the right way to do this?</p>

289,845 | <p>Why must <code>Type.Equals(t1, t2)</code> be used to determine equivalent types, and not the equality operator (e.g. for VB.NET, <code>t1 = t2</code>)? </p>
<p>It seems inconsistent with other parts of the .NET API.</p>
<p>Example in VB.NET:</p>
<p><code>If GetType(String) = GetType(String) Then
Debug.Print("The same, of course")

289,865 | <p>I have a web page that uses a frameset.</p>
<p>Due to scripting and object dependencies, I need to load the frames in a specific order.</p>
<p>I have used this example as a template:
<a href="http://javascript.internet.com/navigation/frames-load-order.html" rel="nofollow noreferrer">The JavaScript Source: Navigation: Frames Load Order</a></p>
<p>This loads an empty page in place of the page I need to load last, then replaces it with the correct page after the first page has loaded.</p>
<p>However: I also need to use the browser Back button. If you run the sample at the above link, let both frames load, then click the Back button, the top frame reverts to the temporary blank page. It is then necessary to click the Back button again to navigate to the page before the frameset.</p>
<p>Is there a way to force frames to load in a specific order without this Back button behavior - or a way to force the Back button to skip the empty page?</p>
<p>This needs to work with Internet Explorer 6 and 7 and preferably with Firefox 3 as well.</p>

289,900 | <p>I am working on turbo C on windows where char takes one byte.Now my problem is with the below union.</p>
<pre><code>union a
{
unsigned char c:2;
}b;
void main()
{
printf("%d",sizeof(b)); \\or even sizeof(union a)
}
</code></pre>
<p><p>This program is printing output as 2 where as union should be taking only 1 byte. Why is it so?
<p>for struct it is fine giving 1 byte but this union is working inappropriately.
<p><b>And one more </b>thing how to access these bit fields.</p>
<pre><code>scanf("%d",&b.c); //even scanf("%x",b.c);
</code></pre>
<p><p>is not working because we cannot have address for bits.So we have to use another variable like below</p>
<pre><code>int x;
scanf("%d",&x);
b.c=x;
</code></pre>
<p><p>cant we avoid it?? is there any other way???</p>

289,916 | <p>I always hear that using "lastInsertId" (or mysql_insert_id() if you're not using PDO) is evil. In case of triggers it obviously is, because it could return something that's totally not the last ID that your INSERT created.</p>
<pre><code>$DB->exec("INSERT INTO example (column1) VALUES ('test')");
// Usually returns your newly created ID.
// However when a TRIGGER inserts into another table with auto-increment:
// -> Returns newly created ID of trigger's INSERT
$id = $DB->lastInsertId();
</code></pre>
<p>What's the alternative?</p>

289,965 | <p>I would like to create a simple program (in Java) which edits text files - particularly one which performs inserting arbitrary pieces of text at random positions in a text file. This feature is part of a larger program I am currently writing.</p>
<p>Reading the description about java.util.RandomAccessFile, it appears that any write operations performed in the middle of a file would actually overwrite the exiting content. This is a side-effect which I would like to avoid (if possible).</p>
<p>Is there a simple way to achieve this?</p>
<p>Thanks in advance.</p>

289,978 | <p>I've got mssql 2005 running on my personal computer with a database I'd like to run some python scripts on. I'm looking for a way to do some really simple access on the data. I'd like to run some select statements, process the data and maybe have python save a text file with the results.</p>
<p>Unfortunately, even though I know a bit about python and a bit about databases, it's very difficult for me to tell, just from reading, if a library does what I want. Ideally, I'd like something that works for other versions of mssql, is free of charge and licensed to allow commercial use, is simple to use, and possibly works with ironpython.</p>

290,007 | <p>Imagine you had a group of product categories organized in a nice tree hierarchy and you wanted to provide hackable urls to browse these. You could do something like this</p>
<pre><code>/catalog/categorya/categoryb/categoryc
</code></pre>
<p>You could then quite easily figure out which category you should list the products for (note that the full URL is needed since you could have categories with the same name but at different locations in the hierarchy)</p>
<p>Now what would be a good approach to add product information in that as well? To give you an example, you wanted to display the product Oblivion for this category </p>
<pre><code>/catalog/games/consoles/playstation/adventure
</code></pre>
<p>It's tempting to just add the product at the end of the url</p>
<pre><code>/catalog/games/consoles/playstation/adventure/oblivion
</code></pre>
<p>but the moment you do so you loose the ability to know if its category or a product which is called oblivion. I personally feel that not being forced to add a suffix such as .html</p>
<pre><code>/catalog/games/consoles/playstation/adventure/oblivion.html
</code></pre>
<p>would be the nicest solution and using some sort of prefix, such as </p>
<pre><code>/catalog/games/consoles/playstation/adventure/product:oblivion
</code></pre>
<p>You could also add some sort of trigger like</p>
<pre><code>/catalog/games/consoles/playstation/adventure/PRODUCT/oblivion
</code></pre>
<p>not as nice either and you would (even though its very unlikely it would be a problem) restrict yourself from having a category called <em>product</em></p>
<p>So far a suffix solution looks like the most user-friendly approach that I can think of from the top of my head but I'm not fond of having to use an extension</p>
<p>What are your thoughts on this?</p>

290,011 | <p>I distribute my application using a VS2008 install package, which normally works great. When I create new versions of the app, I go in and increment the <code>Version</code> property on the install package and verify the <code>RemovePreviousVersions</code> property is set to True.</p>
<p>This works just fine most of the time - I just run the install package for the newer version and the older version is uninstalled and the newer version replaces it.</p>
<p>However, occasionally the install package will run successfully, but when I start the program the old version starts up. Apparently the old version of the .exe is still present.</p>
<p>I end up having to completely uninstall the software and install the new version, which always works, but is a pain.</p>
<p>The file isn't in use as far as I can tell and the install package doesn't tell me to reboot.</p>
<p>Any ideas about what's going on here?</p>

290,034 | <p>I've got a bunch of legacy code that I need to write unit tests for. It uses pre-compiled headers everywhere so almost all .cpp files have a dependecy on stdafx.h which is making it difficult to break dependencies in order to write tests.</p>
<p>My first instinct is to remove all these stdafx.h files which, for the most part, contain #include directives and place those #includes directly in the source files as needed.</p>
<p>This would make it necessary to turn off pre-compiled headers since they are dependent on having a file like stdafx.h to determine where the pre-compiled headers stop.</p>
<p>Is there a way to keep pre-compiled headers without the stdafx.h dependencies? Is there a better way to approach this problem?</p>

290,035 | <p>Does anyone know in .Net 2.0 - .Net 3.5 how to load a jpeg into a System.Windows.Forms.WebControl as a byte-array and with the right mimetypes set so it will show?</p>
<p>Something like:<br></p>
<pre><code>webBrowser1.DocumentStream = new MemoryStream(File.ReadAllBytes("mypic.jpg"));
webBrowser1.DocumentType = "application/jpeg";
</code></pre>
<p>The webBrowser1.DocumentType seems to be read only, so I do not know how to do this. In general I want to be able to load any kind of filesource with a mimetype defined into the browser to show it.</p>
<p>Solutions with writing temp files are not good ones. Currently I have solved it with having a little local webserver socket listener that delivers the jpeg I ask for with the right mimetype.</p>
<p>UPDATE: Since someone deleted a answer-my-own question where I had info that others could use, I will add it as an update instead. (to those who delete that way, please update the questions with the important info).</p>
<p>Sample solution in C# here that works perfectly: <a href="http://www.codeproject.com/KB/aspnet/AspxProtocol.aspx" rel="nofollow noreferrer">http://www.codeproject.com/KB/aspnet/AspxProtocol.aspx</a></p>

290,055 | <p>I have an have an ASP.Net page which contains a button. This Page contains a ServerSide Paypal button.</p>
<p>When pushed my server does various clever things on the back end and then rewrites the response as a form and some javascript which posts this form to paypal..</p>
<p>This all works great.</p>
<p>However, if the user then elects to click back, they will arrive at my generated self-posting form and that will forward them again to Paypal. </p>
<p>I thought if I could find a way to have my generated form page not exist in the history, then this will solve my problem. but I have no idea how to correct this.</p>
<p><strong>How can I remove my page from the history or just have it never appear?</strong></p>
<p>Update: Thanks to all... Those are some great answers. Upvoted all good ones but went with splattne on account of clever use of hidden field rather than cookies for basis of decision.</p>

<p>I'm trying to change an element (li) to another element (div) after the (li) has been dropped.</p>
<p>Sample code:</p>
<pre><code>$("#inputEl>li").draggable({
revert: true,
opacity: 0.4,
helper: "clone"
});
$("#dropEl")
.droppable({
accept: ".drag",
hoverClass: "dropElhover",
drop: function(ev, ui) {
// change the li element to div here
}
});
</code></pre>
<p>The problem is, when i use</p>
<pre><code>drop: function(ev, ui) {
$(ui.draggable).replaceWith("<div>Some content</div>");
}
</code></pre>
<p>the original draggable elements will be disabled when the function above is triggered.</p>
<p>I'm using the latest jQuery and jQuery UI stable versions.</p>

290,112 | <p>I have a Panel and I am adding controls inside this panel. But there is a specific control that I would like to float. How would I go about doing that?</p>
<p>pnlOverheadDetails is the panel name</p>
<pre><code>pnlOverheadDetails.Controls.Add(lnkCalcOverhead);
</code></pre>
<p>The control named lnkCalcOverhead is the control I'd like to float.</p>
<p>Thanks in advance</p>
<p>EDIT: By float I meant the css style not anything fancy :)</p>

<p>So its obviously some sort of server timeout or the server's just returning back mangled garbage. This generally, unfortunately not always, happe</p>

290,133 | <p>Our website uses Perl to provide a simple mechanism for our HR people to post vacancies to our website. It was developed by a third party, but they have been long since kicked into touch, and sadly we do not have any Perl skills in-house. This is what happens when Marketing people circumvent their in-house IT team!</p>
<p>I need to make a simple change to this application. Currently, the vacancies page says 'We currently have the following vacancies:', regardless of whether there are any vacancies! So we want to change it so that this line is only displayed at the appropriate times.</p>
<p>I could, obviously, start to learn a bit of Perl, but we are already planning a replacement site, and it certainly won't be using Perl. So since the solution will be trivial for those with these skills, I thought I'd ask for some focused help.</p>
<p>Below is the start of the procedure that lists the vacancies. </p>
<pre><code>sub list {
require HTTP::Date;
import HTTP::Date;
my $date = [split /\s+/, HTTP::Date::time2iso(time())]->[0];
my $dbh = DBI->connect($dsn, $user, $password)
|| die "cannot connect to $database: $!\n";
my $sql = <<EOSQL;
SELECT * FROM $table where expiry >= '$date' order by expiry
EOSQL
my $sth = $dbh->prepare($sql);
$sth->execute();
while (my $ref = $sth->fetchrow_hashref()) {
my $temp = $template;
$temp =~ s#__TITLE__#$ref->{'title'}#;
my $job_spec = $ref->{'job_spec'};
...etc...
</code></pre>
<p>The key line is <code>while (my $ref = $sth->fetchrow_hashref()) {</code>. I'm figuring that this is saying 'while I can pull off another vacancy from the returned recordset...'. If I place my print statement before this line, it will always be shown; after this line and it was be repeated for every vacancy.</p>
<p>How do I determine that there are some vacancies to be displayed, without prematurely moving through the returned recordset?</p>
<p>I could always copy the code within the while loop, and place it within an if() statement (preceding the while loop) which will also include my print statement. But I'd prefer to just have the simpler approach of <code>If any records then print "We currently have.." line</code>. Unfortunately, I haven't a clue to code even this simple line.</p>
<p>See, I told you it was a trivial problem, even considering my fumbled explanation!</p>
<p>TIA</p>
<p>Chris</p>

290,187 | <p>I have a script that takes a command and executes it on a remote host. It works fine, for example:</p>
<pre><code>$ rexec "ant build_all"
</code></pre>
<p>will execute the "ant build_all" command on the remote system (passing it through SSH, etc).</p>
<p>Because I'm lazy, I want to set up an alias for this command (and ultimately, several others), such that, for example, I can just invoke</p>
<pre><code>$ rant build_all
</code></pre>
<p>and bash will it will automatically invoke </p>
<pre><code>$ rexec "ant build_all"
</code></pre>
<p>I tried doing this with alias, but if I define</p>
<pre><code>alias rant=rexec ant
</code></pre>
<p>then any arguments passed to "rant" will just be appended to the end, like so:</p>
<pre><code>$ rant build_all -Dtarget=Win32
(interpreted as:)
$ rexec "ant" build_all -Dtarget=Win32
</code></pre>
<p>This fails, because rexec really takes just one argument, and ignores the others.</p>
<p>I could probably do this with a bash wrapper script, but I was wondering if bash had any built-ins for doing this for me, perhaps a named-argument version of alias, or a perl-like quote string command (e.g. qw/ / ), or some such.</p>

290,214 | <p>Is it possible to retrieve variable set in <code>onreadystatechange</code> function from outside the function?
<bR>--edit--<BR>
Regarding execution of functions:<BR>
If its possible i would like to execute ajaxFunction() with one click<BR>
and then popup() with next click, or
somehow wait for ajax function to end and then call for alert box<BR></p>
<p><BR>In pseudocode:</p>
<pre><code>function ajaxFunction(){
//creating AJAX
...
// Create a function that will receive data sent from the server
ajaxRequest.onreadystatechange = function (){
if(ajaxRequest.readyState == 4){
//success code
======>Here i want to set variable <=====
var MyVariable='MyContent';
}
}
//Retrieving page
....
}
function popup(){
ajaxFunction();
alert(MyVariable);
}
</code></pre>

290,226 | <p>I have a query that works on Postgresql 7.4 but not on Postgresql 8.3 with same database.</p>
<p>Query:</p>
<pre><code>SELECT * FROM login_session WHERE (now()-modified) > timeout;
</code></pre>
<p>Gets the following error:</p>
<pre><code>ERROR: operator does not exist: interval > integer
LINE 1: ...ELECT * FROM login_session WHERE (now()-modified) > timeout ...
^
HINT: No operator matches the given name and argument type(s). You might need to add explicit type casts.
</code></pre>
<p>Column <code>modified</code> is a <code>timestamp</code> and <code>timeout</code> is an <code>integer</code>.</p>
<p>Is there some settings I need to change on server?</p>
<p>I'm installing an application for a client on new server (ubuntu) so I can't change queries in the application.</p>
