RE: Delegate for control embedded into MFC

Hi,

Based on my understanding, you have a managed Visual C++ Windows Forms
Control Library project and a UserControl in this project. You add the
UserControl on a form within a C# WinForms application project. You want to
add a CWnd object to the UserControl and use CWinFormsControl class to
embed a Button into the CWnd object. Then you'd like to register the Click
event of the Button in the form within the C# project. If I'm off base,
please feel free to let me know.

In my opinion, to register the Click event of the Button in C# project, you
only need to use the += operator, just like you do with the simple scenario
you mentioned at the beginning of your post.

I notice that your sample method 'CreateControl' create a new control,
which may conduct that the actual Button control shown in the CWnd object
is not the one that you're attempting to add into the CWnd. Maybe this is
the reason why the btn_Click handler isn't invoked in your project.

If the problem is still not resolved, you may send me a simple project that
could just reproduce the problem. To get my actual email address, remove
'online' from my displayed email address.


Sincerely,
