Hello,
I'm having an issue with a dotNet component I wrote. The component is
basically a Winform usercontrol, hosting in a tableLayoutPanel a WPF
component (external librairy .dll).
I'm registering this Winform component to COM interop to include it as
an ActiveX control into an existing Visual Studio 6 MFC application.
Moreover, I would like my ActiveX control (understand the whole .NET
thing, especially the WPF part) to resize to the size of the MFC
hosting window.
Everything is working well if I set up 3 anchors points for my
tableLayoutPanel (left, right, top for eample. In this case, the
control resize only its width), but as soon as I want to set-up 4
anchors points, or to put the dock property to "fill", when I run the
MFC application (hosting the .NET stuff), I get an error :
"Microsoft .NET Framework
Unhandled exception has occured in a component in your application. If
you clicl Continue, the application will ignore this error and attempt
to continue" (which fails, actually... "unhandled exception, access
violation" in the visual studio 6 debugger)
"Exception from HRESULT: 0x88980406"
There is a detail button, and I get this when I expand it :

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.
For example:
<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>
When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.
///////////////////////////////////////////////////////////////////////////
I don't know why there is an exception thrown when I put 4 anchors and
not when I only put 3 of them.
If there is something fondamentaly wrong with my way of doing things,
please let me know, and give me advice for a better way.
Thanks in advance
