Then let's be more precise:
Most, if not all, .NET langauges can call DLL's / OCX's, true. But that
won't help Colin.
Delphi.NET is the only one that can create DLL's with IL code inside, that
can be called from mapbasic. No additional wrappers required. Perhaps
managed C++ can also do it now, I can't say for sure.
Last time we discussed this I created this small setup:

Not quite right ..
All of .NET supports ordinary, Win32 DLLs (and ActiveX DLLs) - the problem
is just to get MapBasic to call a DLL that's a wrapper to the .NET
application. For that, you're right that you would need to write a C-call
convention DLL in C++ or Delphi.
The problem then just boils down to the usual, with MapBasic - callbacks,
etc.
VB.NET or C#.NET (or for that matter, Cobol.NET or Eiffel.NET) all compile
to much the same IL which the CLR runs in identical fashion.

Colin,
There is only one option to create a DLL based on .NET code that can be
called from mapbasic without any further wrappers:
Delphi.NET
You can be dead sure VB.NET doesn't support such an old-fashioned thing as
DLL's - not even VB6 did that. VB tools and mapbasic just doesn't match
up.
Perhaps with a wrapper written in some other language (C++ / delphi).

Uffe
