Hi everyone,

I know. This question has been asked several times on the Net but I'm looking for a way to avoid the [declspec] thing.

Because I have made a .dll of my C++ project and added that .dll file as a reference to my C# project. Now If I'm honest I don't quite know how to pass over a c# string to a c++ string. I have tried alot of things but it's not working until now.

C# code:

[...]
                if (dlg.ShowDialog() == DialogResult.OK)
                {
                    strToSend = dlg.SelectedPath;
                    obj.SetString(strToSend);

                }
[...]

C++ code:

[...]
void OpenCvWrapper::SetString(string s)
{
	//do stuff with string

}
[...]

Is there another way?

Thanks,

Andries
