Win32 dll

It looks like I'll have to dive into C++. Thank you for your answers Simon. Francis

oh... i think i got the wrong way round, you wannt to call managed code from your unmanaged code... I'm not sure if this is possible... Cheers Simon

Hi again.... The right way would be to write a managed wrapper in mc++ (managed c++), that handles the unmanaged part and gives you a bridge to the managed part. The easier way is to use P/Invoke, that gives you the possibility to call unmanaged (=win32) code from managed code (=.net). Google is full of P/Invoke articles... http://msdn.microsoft.com/msdnmag/issues/03/07/NET/ Hope i helped a bit. Cheers Simon

Simon, Thanks for your help. I cannot use COM with this 3rd party application. So if .NET cannot compile a Win32 dll, then can C++ with .NET extensions compile one? (it would connect to my C# methods and properties and expose C methods) Any pointers on how I should do this? I haven't programmed in C for 16+ years. Thanks, Francis

Hi If you write a library with c# (and .net framework), the resulting dll will be a .net assembly. So, it is not possible to compile c# code to a win32 dll... But interoprability of .net and com components should not be a problem. a.) use com types in .net http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpguide/html/cpconcominteropsamplenetclientcomserver.asp b.) use .net types in com types http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpguide/html/cpconexposingnetframeworkcomponentstocom.asp I hope i helped a little bit. Cheers Simon
