Hello,
I've written a Windows Forms application in .NET 2.0 and am exposing
it to COM using the checkbox in Project Properties and by adding some
register functions and adding it to the GAC. I'm using the ActiveX
Test Container (tstcon32.exe) and I'm able to add the control to the
container. All this works, well almost... I'm using some Invoke calls
from worker threads that update the GUI. In native .NET this means
that stuff is done on the GUI thread, which is accessed by using a
pointer to the parent window. Of course, in a container we don't have
such a thing. My initial thought was to use the HWnd pointer of the
Container window and I can find this value my looking up
CurrentProcess and all. But how do I couple that value to the Invoke
call ? Maybe this is not the recommended way...
Any thoughts ?
Regards,
Janiek 1 3082
Hi guys,
Found the mistake. I attached event handlers to the worker threads in
my GUI constructor. In a .NET application this went well, however in
an ActiveX container this went wrong. I simply moved the event handler
attachments to the control's Load() event. This seems to work.
Greets,
JB

I seem to have run into two documented bugs whose workarounds are
incompatible. What I have is an OCX written in VB 6 that has a few classes
in it. Many of the methods of the OCX are used by ASP, and so far have
worked fine.
I recently added a COM object reference to the DLL which consists of an SMTP
client dll that is wrapped up in dual interface...

Hello
In order to host and use an ActiveX control (non-GUI) in a WTL app, I
followed the following steps:
1. During project creation, the ActiveX Hosting option is enabled.
2. In the dialog editor, the ActiveX control was inserted.
3. An event was added to the dialog by right clicking on the control
and selecting 'Events...'.
4. VS automatically created a .tlh file.

I have a UserControl with a couple of textboxes and a couple of buttons
