Problems with wxWidgets, Visual Studio and "OLE", probalby clr related

[Reinhard Pagitsch]

Hallo Alexander,

not to know OLE
Did you looked at: 
http://msdn2.microsoft.com/de-de/library/h8027ys9(VS.80).aspx

In this page there is also a link to /clr (Common Language 
Runtime-Kompilierung).

/EHsc is "Enable C++ exception" as I can see in my compiler options.
( I use VS 2005 express)

regards
Reinhard
