Yes, I did.

I found the problem. Obviously System::Windows::Forms::Control::FromHandle fails for window handles, which were created by Win32/MFC and not with .NET. Thinking about it, this makes sense.

Luckily I found a nice tutorial on the web, which pointed me into the right direction:
http://www.tech-archive.net/Archive/DotNet/microsoft.public.dotnet.languages.vc/2005-07/msg00752.html

So I moved the code, which attaches to control to the parent window, from the .NET to the native code section.

The .NET control creation changed simply to the following:

public override System.Windows.Forms.Control CreateSettingsWindow()
{
	return new MySettingsControl();
}


And the attachment to the parent uses the good old Win32 function SetParent:

HWND CreateSettingsWindow(HWND wndParent)
{
	System::Windows::Forms::Control^ ctrlSettings = (*this->m_pWrappedPlugIn)->CreateSettingsWindow();
	if (ctrlSettings != nullptr)
	{
		::SetParent((HWND)ctrlSettings->Handle.ToPointer(), wndParent);
		return (HWND)ctrlSettings->Handle.ToPointer();
	}
	else
	{
		return NULL;
	}
}



Might it be worthwhile to publish an article about this here on codeproject?


Thanks
