C# DLL in VC++
-
I'm trying to use a form I created in C# in a VC++ program I am creating. (Descriptive subject, no?) I have the C# compiling into a DLL and ... well that's about as far as I can get. I've done some reseach in the MSDN, and it shows how to use console classes, but nothing about how to use a form created in C#. I don't have the code on this computer, but the method I found I was trying last was using the following code (Close as I can 'member) #using //However main CLR dll is spelled. #using "MyCSharpDLL.dll" using namespace MyCSForm;//I tried it with and without this //line and it didn't work either way, so I show it. That's about where I get to. I also try to create an object of the class in the name space using either MyForm Form1; OR MyCSForm::MyForm Form1; Depending on if I use the "using namespace MyCSForm;" line or not. I have also tried to using a slightly more complex method, one that is used to load functions from a DLL. I use that method to pull things out of a C++ dll that uses dllexport to say what comes out. That method can load the C# DLL but I can't figure out what I would be trying to load from it. Tried and failed to do the form, and main and even the namespace. None worked. At least I don't know how to get them to work. Any help would be appreciated and if you have question I will answer them to the best of my abilities. And if I am going all wrong on how to load a DLL made in C# into C++, please point me in the right direction. :) Thanks. Note: I'm sorry if I seem to be flooding the forum, but I'm not sure which of the three (Visual C++, Managed C++, C#) I am posting this in would be the best place for it. Since it deals with all three of them, I believe. Thank you again for any help. The wisest of the wise may err. - Aeschylus

You have several options : - export the C# assembly to a COM component (regasm.exe) and use it from your VC++ program like a normal COM component. This article[^] (Nick Parker) tells how to. - use MC++ mix mode, where your code references the namespace and class written with C#. #using <MyCSharp.dll> using namespace MyCSForm;, and of course you need to compile with VC++7.x with the /clr switch.
