use C header file in a VB project
-
Hi all, I'm developing an application in VB2005.Net 2.0 and I would like to use a C header file that contains many structs that I need in the project. This structs are going to change quite often so I wouldn't like to migrate the structs from the C file to VB code each time that the header file changes. The best thing for me would be to include the '.h' file directly into my project so I could access it directly. Is it possible to do it in any way? Could it be possible to do it encapsulating the '.h' file into a library and then reference it from the VB project? Thanks in advance for any idea you have, Marc Soleda

Perhaps if you make a C++/CLI dll, you could do it.
Christian Graus Please read this if you don't understand the answer I've given you "also I don't think "TranslateOneToTwoBillion OneHundredAndFortySevenMillion FourHundredAndEightyThreeThousand SixHundredAndFortySeven()" is a very good choice for a function name" - SpacixOne ( offering help to someone who really needed it ) ( spaces added for the benefit of people running at < 1280x1024 )

I've done it but I just have access to the struct name and not to its subelements. I mean: In the .h header file:
.... public struct S_ERRORS{ unsigned char uHall2; unsigned char uHall1; } ...Inside the VB project, I can declare a S_ERRORS variable but I cannot access to its element: uHall1, uHall2 Is there any way to access to this elements?

Done what?? Did you compile this into a MANAGED (C++ CLI) .DLL or into a normal Windows library .DLL (unmanaged code). If unmanaged, you won't be able to use the structures defined in the .DLL.
