You either change it for the whole system using the Display control panel, or you complete draw the window frame yourself, which requires knowledge about the Window APIs and P/Invoke. If you want to venture down that route, I highly suggest you read all of Interoperating with Unmanaged Code[^] (pay close attention to the marshaling topics) and search this site for examples of owner-drawn window frames.
BTW, the link doesn't work.

I have a usercontrol with a few controls on it. In the load of my usercontrol I read the settings from the registry. I also want to write these settings back to the registry when my usercontrol is unloaded. But there is no such thing as unload.
Can anyone tell me which event to use to write these settings to the registry?

That wouldn't work. Disposed happens after the control is disposed, so his controls that contains the values and any fields or properties that might reflect those values are already gone.

Handling the Disposed event is too late. You need to override Dispose(bool), persist your data, then call base.Dispose(bool) like so:
protected override void Dispose(bool disposing)
{
PersistToRegistry();
base.Dispose(disposing);
}That way the child controls and other data is disposed after you get the data contained within. Once those controls are disposed you can't get their data (because it's been disposed).

Hi,
my chat client is easily connecting to the Server program using Sockets (in c-sharp). But
now i want to provide the functionality in my chat client program to be able to connect
through proxy. How can I do this.
Besides, I see in MSN, that there are 3 types of Proxy setting in it i.e.
- SOCKS VERSION 4
- SOCKS VERSION 5
- HTTP Proxy
would it make a major difference in the client side coding if i have to support all the
above types?
A prompt reply will be appreciated.
Regards,
Kamran

Your protocol has to be defined to work with proxies - it isn't automatic. The only advice anyone can really give you is to read the RFCs from http://www.ietf.com/rfc[^] for those proxy types to determine how you could include them along with your protocol definition.
HTTP, for example, allows for proxies. This is why the HTTP-related classes (like HttpWebRequest) support proxies (a la the WebProxy) in the .NET BCL. It's common enough to warrant inclusion in the .NET BCL. How other protocols work with proxies is up to the protocol authors. Many typically work the same (there's a lot of HTTP-like protocols, like SMTP, DICT, etc.) so I'd imagine the proxy support works the same, making it easy to use the same proxies.
What I'd recommend is using a good OO design to encapsulate your Socket client in a class and actually make use of the WebProxy for consistency (so people can reuse the same proxy; WebProxy also defaults to using the Internet Explorer settings for proxies, making it easy for your users to default to settings they might've already configured). You still need to work out how it'll work with your chat protocol, though.

From what I can tell, the MDIList property that you used to set on a menu to make it display an MDI window list has been changed to become a MdiWindowListItem property on the MenuStrip itself
I set this to my Window menu, and it works fine when I open the first child window - Screenshot 1[^] but when I have more than one child it goes out of control: Screenshot 2[^]
(basically every time a new child window is created, it seems to add new menu items from scratch, so the existing items get left behind)
Am I doing something drastically wrong here, or is this just incomplete .NET 2.0 stuff? (I've searched everywhere for documentation on this, but haven't been able to find anything!)

There's a reason they call it ".NET 2.0 Beta 1".  Beta 2 is to be released early next year and you could probably expect it to be fixed by then. There's been a lot of bugs that the feature teams have been getting through so build a solid framework.
Honestly I've never used the MdiWindowListItem in a winbar, though, so I don't know if this is a common problem or if your environment enables such a bug. Therefore, I suggest you go to http://lab.msdn.microsoft.com/vs2005/[^] and search to see if this has been reported. Keep the query simple, like just "MdiWindowListItem".

Again, it's beta so they probably don't want anything indexed. Some web crawlers cache for a long time.

Hello,
I get this error when the program compiles, when the message box asks me to continue i can click yes and the program will still run. However, l would like to get rid of this error.
The only things l have done before l got this error was changing the startup object in the project properties and changing the Void main into another form. Thats all l think.
Could not open incremental build file 'C:\IBS LibrarySystem\LibrarySystem\obj\Debug\LibrarySystem.exe.incr' for writing
Hope someone can help me,
Steve

While all those changes should've touched the files so that they get rebuilt and re-linked correctly, that apparently hasn't happened.
Use Rebuild instead of Build and see if that sorts out the problem. That will clean (delete) the project targets and rebuild again.

Hi,
I am using Process.Start("file.pdf") to launch the default pdf reader and open a file. This works the majority of the time. However during deployment I came across a few computers where this does not work. It does absolutely nothing. The reader is not launched and the file is not opened. However, on those computers if they manually launch their reader and then run the above code the file gets opened.
Has anyone come across this problem before? Does anyone know what is happening?
It is not a problem with the reader not being associated with the pdf file format. I know this because when they double click a pdf file from explorer it opens just fine.
Thanks,
Karl

And what exception handling do you have around Process.Start? Are you just catching exceptions and not doing anything with the exception data (like displaying a user-friendly error, which is the least you should do)?
Process.Start - the way you're calling it - uses ShellExecuteEx, the same API that the Windows Shell uses when you double-click files. There's really no difference.
So then you should ask yourself what the other factors may be. Are you expecting that the current working directory will be the directory in which the EXE is located? This doesn't have to be the case. The working directory can be any directory.
So, if this was some sort of help file and you expected it to be in the same directory as your application, then you should construct the fully-qualified path using either the Assembly.Location property or Application.StartupPath like so:
string path = Path.GetDirectoryName(Application.StartupPath);
path = Path.Combine(path, "help.pdf");
Process.Start(path);

Thanks for your response. I am dealing with exceptions and none are getting thrown. It is also not a problem with the path. I can be sure of this because if you already have your reader open then the code will open the pdf file in your reader.
Why would Process.Start behave differently when the reader is already open? This may not be a problem with my code, it may be a problem with the .NET framework, the windows API, or even Adobe's stuff. I am unable to find the cause.
Thanks

Some applications - like Office and Adobe Acrobat/Reader - register documents (file monikers) into the ROT (running object table) associated with the application. When a new document is opened, the file persistence handler (typically; this is actually implementation-specific, but is a fundamental technology in COM) checks for running objects and if it is found, activates it. Since the application is running, it doesn't need to be opened again. The new document is opened and registered in the ROT. If this was an existing document, it activates it.
It still shouldn't behave differently, however.
Perhaps try being more explicit, like so:
ProcessStartInfo psi = new ProcessStartInfo("file.pdf");
psi.UseShellExecute = true;
psi.Verb = "open";
Process.Start(psi);Depending on the operating system this could yield different results. On Win96 the verb "open" is always assumed where with NT its whatever the default is (which could be different than "open"). You can find this out by looking at the File Types tab in the Folder Options control panel.

If you don't like it - and I'd certainly say the same thing - then don't post non-C#-related questions here. Do you ask your doctor about car troubles?
This forum is only for C#-related question and how to make the proper calls with the .NET BCL. No third-party library questions are accepted, and ASP.NET-related questions (whether written in C#, VB.NET, or any other managed language) should be sent to the ASP.NET forum (it's more specific).

Wow.  I'm not sure how to help you. There's a lot of information that you want to insert into a small table. Well the syntax for insert goes as follows:
INSERT INTO table_name(colname, colname, colname) VALUES (val, val, val...)
Try asking in SQL forum[^] next time.
