Hi,
How to get the handle of a ListBox control in VB.NET 2005?
I am using
Dim i_Handle As ListBox i_Handle = ListBox1.Handle
But this is not working

Instead of ListBox you must use IntPtr :
Dim i_Handle As IntPtr i_Handle.
You're creating a new ListBox) // You'll see numbers.
Hi,
Handle is an IntPrt (A handle is just a 32-bit integer).

Given a handle of type HWND is it possible to confirm that the handle represents a real window?

By the time you've got confirmation that a Window is valid another process/thread ... .
Generally no.
BOOL isRealHandle = IsWindow(unknwodnHandle);
Look at this link for more information .
There is a function IsWindow which does exactly what you asked for .

I need to determine whether a handle that my code did not create, for which GetFileType()==FILE_TYPE_PIPE , is a socket or not. There does not seem to be an API for this.
I have tried the following. The general idea is to use a socket-specific function...
Answer Snippets (Read the full thread at stackoverflow):
If the call succeeds you know that the handle is a pipe handle, otherwise it must be a socket..
I'm thinking that perhaps you could attempt to call GetNamedPipeInfo() on your handle.
A named pipe...

I have a C++ RAII class for managing Win32 HANDLEs using boost::shared_ptr<> that looks a bit like this:

Why? Because it is a waitable handle concept, including the Win32 Event, Mutex, Auto reset kinds, Thread, all of it apart from critical_section (which also has a backing handle deep within for:

Is there any Win32 API to check if a given handle belongs to the current process?

I don't know how easy is to get a process handle from some other handle.....
From a process handle you get the id with GetProcessId Function.
From a window handle you can use GetWindowThreadProcessId Function to get process id.

Is there an easy way to remove the QDockWidget's resize handle? My dock widget can't be resized (the sizepolicy is fixed), so having the handle there is just redundant.

The handle is drawn as a separator by the QMainWindow instance & I believe the only way to modify.

I have an application that IMPLICITLY opens a handle on a dll/file. At some point in the application, I want to release this handle. How can I do it? My application is in C#.

I don't know an easy way to close the handle, which would most likely just crash your program if .NET tries to access Boolean CloseHandle(IntPtr handle);.
Just use the Dispose or Close method of the class that opened the handle.
