Hi All, Here is my 2 cents worth, since I was asleep while this was happening.
With MS Visual Studio .NET, Borland Delphi Studio, and #develop you can create a Win32 DLL that can be called from MapBasic and contains .NET code, and controls, etc code without any additional coding. I prefer using C# and it wasn't a huge learning curve to move from VB. Engage3D is a .NET product that runs from inside MapInfo (http://www.encom.com.au). Unfortunately I don't have a sample that I can share. The interaction between MapInfo and a DLL can easily be achieved with an OLE call back to MapInfo. This is easy to setup and works well. Hope this helps.

And Delphi is perhaps unique in combining Win32 and .NET code (I don't know), but it still remains a possibility that any C-calling convention DLL (eg, one made with unmanaged C++ or C code / compiler) would be able to run a .NET assembly, and that .NET assembly could talk back. That's all I was saying .. Maybe Colin's probably better advised to look at MapXtreme .NET? (except for the cost - writing a bit of C++ and some .NET code in even the so-uncool VB.NET is as cheap as zero $ - more if Visual Studio is purchased). --- Ian Thomas GeoSciSoft - Perth, Australia -----Original Message----- From: Uffe Kousgaard [mailto:[EMAIL PROTECTED] Sent: Thursday, October 27, 2005 5:14 PM To: Mapinfo-L Subject: Re: MI-L Calling a VB.NET assembly from MapBasic 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.
