hey,

Is there a way to use an unmanaged C++ DLL in C#?

I've tried "converting" the DLL using tlbimp.exe to a RCW. But this gives a an error that it isn't a valid type library.

I've also used the metatag [dllimport()], this gives more result, but not correct(correct text but with preceding strange characters). I've tried using a function that.

Anymore tips on creating the DLL or C# calls?

The reason why it is a unmanaged C++ dll, is because of the files, provided by another company must be used. I've just created a few callable function to use the functions.

Thanx

Another DLL written in C++/CLI would give you a lot of control over the managed to unmanaged calls. It would be a mixed-mode library that links to the unmanaged DLL and exposes the required methods to the C# program through your own classes.

It's not the easiest approach, but it's more flexible and faster than the dllimport method. I've done this for several projects with great results.

By mixed mode you mean(starting from the class with entry point, C#):
1: C#
2: C++/CLI(DLL)
3: Unmanaged C++(DLL)

I'm gonna try this solution. I hope i don't get confused working with all these types ;)...
