I found out that a pointer to a structure is not the same as a pointer to the memory that a structure occupies. This won't work: Marshal.PtrToStructure(twCapability.Handle, twOneValue) But this does: Private Function GetOneValueZ(ByVal twCapability As twsCapability) As String Dim rc ...more >>

Not too familiar with old school C or C++/CLI, but this is how I would accomplish this task in C#.
