C# and C++ together... is it possible?

[TomaHawKPT]

Hi,

I have no experience at all in the .NET world, and I'd like to ask you if it is possible to mix together C# and C++.

The problem is that I must develop a GIS application in .NET that will use a ActiveX that has an interface in C++.
Can I "comunicate" with that ActiveX from a C# application?

Thank you,
TomaHawK

Dunno much about activeX, but I would use COM to communication between c++ and C#. I do all the time.

Yes, it is very possible and in fact not very hard. Once you create your C# project, add your C++ ActiveX code as a reference by right-clicking References, going to the COM tab, and then browsing for your component. This will automagically create an Interop.whatever.dll so that your C# can communicate with the ActiveX.

Alternatively, you can probably add your ActiveX as a control, if it is one, by richt clicking on the controls section on the left side of the IDE and choosing add control or something along those lines.
