Hi all

Does anybody knows the code behind System.Windows.Forms.Control.Invoke

Is it using Win32 SendMessage with some WM_USER + x message

Any hints would help

I have a mixed environment (MFC, Win32 and .NET) and need to resolve some issue with windows message queue

Thank
JPRoot

Next question: same thing but with BeginInvoke/EndInvoke
Thank

Hi JPRoot,
I would say that ControlInvoke uses SendMessage and BeginInvoke\EndInvoke
uses SendMessageCallback, but what I see is that both of them post a message

Hi,

Could you write a small winform program and look into it using Spy++?
I guess it will show the message id and if the message is sent or posted.

If you still have problem on this issue,
please reply this thread to let me know.
