[Mono-list] Help in dealing with Mono/.NET PInvoke issue

[Dinis Cruz]

Hi Chris,

I've just checked-in the code that contains this project, so now all
relevant source code is on the O2Platform
sourcecode<http://code.google.com/p/o2platform/source/checkout>

Here is the list of the PInvokes that (I think) are causing the problem

   - Win32 Native methods:
   http://code.google.com/p/o2platform/source/browse/trunk/SourceCode_3rdParty_Dlls/DockPanel/WinFormsUI/Docking/Win32/NativeMethods.cs
   - Win32 Enums:
   http://code.google.com/p/o2platform/source/browse/trunk/SourceCode_3rdParty_Dlls/DockPanel/WinFormsUI/Docking/Win32/Enums.cs

To easily replicate this, please use this project
http://code.google.com/p/o2platform/source/browse/trunk/O2%20-%20All%20Active%20Projects/O2Core/O2/O2.sln
since
it only loads up that GUI and when executed (OSx 10.6) throws this error
message:
