Here is what I have done so far...

I created a SF Business Object Library Project and made it COM Visible. I then added a SF User Control and placed a few controls on it for testing. I created one public property on the user control.

I then created a VB6 app and using the VBControlExtender, I was able to Add the user control to my form and make it visible, although only a few controls appeared. (Haven't figured out why yet).  I can't seem to set the public property on my user control. I get a out of memory error.

Anyway, just wanted to know if there is a better way to launch a form and pass some values to the user control or form. I will be doing this quite a bit as we migtrate all our apps to vb.net.

Thanks,
Tim

As for a user control, I've never tried to show a user control within another application.  I know that platform interop when IntPtr handles are shared within a form can be tricky.  So, if you can show a whole .NET form rather than just a .NET user control, you'd probably be better off.  Why only a few of the buttons became visible I do not know.  The only pointers I can provide would be to create a .NET method that you can call from VB6 that will initialize the .NET app domain.  We call ours SetEnvironment(), and it does thinks like EnableVisibualStyles = True, DataBasics.DataSources.Add(), etc.  Anything that you would normally do from within your AppMain.vb, you will need to do in this method to initialize all of the .NET stuff.

I created a quick .NET calling program that refereces my COM dll and it seems to work fine from here.

Any idea's what is causing this and what I need to correct this.

Thanks
