Ok, I think I sent this last email too quickly. If I try to use the
PROPVARIANT struct as defined, it blows up on me when the type is loaded.
An unhandled exception of type 'System.TypeLoadException' occurred in
felix.dll
Additional information: Could not load type PROPVARIANT from assembly
Everything compiles correctly, so I'm not sure where the problem could be.
Anyone?
[StructLayout(LayoutKind.Explicit)]
struct PROPVARIANT {
[FieldOffset(0)] short vt;
[FieldOffset(2)] short wReserved1;
[FieldOffset(4)] short wReserved2;
[FieldOffset(6)] short wReserved3;
[FieldOffset(8)] sbyte cVal;
[FieldOffset(8)] byte bVal;
[FieldOffset(8)] short iVal;
[FieldOffset(8)] ushort uiVal;
[FieldOffset(8)] int lVal;
[FieldOffset(8)] uint ulVal;
[FieldOffset(8)] long hVal;
[FieldOffset(8)] ulong uhVal;
[FieldOffset(8)] float fltVal;
[FieldOffset(8)] double dblVal;
[MarshalAs(UnmanagedType.Currency),
FieldOffset(8)] decimal cyVal;
[FieldOffset(8)] DateTime date;
[MarshalAs(UnmanagedType.VariantBool)]
[FieldOffset(8)] bool boolVal;
[MarshalAs(UnmanagedType.Error)]
[FieldOffset(8)] int scode;
[FieldOffset(8)] FILETIME filetime;
[FieldOffset(8)] IntPtr everything_else;
}
The SDK definition is here:

Thanks,
Erick
