Dear all,

the documentation states that 'Any 32-bit DLL can be imported in
 Component Pascal...'. As far as I understand this refers to COM dlls.

This task is fairly simply with GPCP:
1) Run TlbImp.exe (from the .NET SDK) on the Dll or preferably the
 corresponding type library (tlb).
2) Run PeToCps.exe (from gpcp).
-> The dll which is created in the first step will translate the calls
 to the COM-dll at runtime using InteropServices. This affects runtime
 performance but works like a charm.

I suppose there is no possibility to do something comparable within
 Blackbox?

Have you perhaps used a semi-automated approach? If so, did you use
 C++ headers, IDL files or something different?


The documentation states:
'Be careful to declare all methods in the method table in the correct
 order with the correct parameter list.'
Does that mean you can not omit parts of an interface?


kind regards
gunnar
