How do I declare a string and pass it from a Visual Basic GUI to a C++ DLL?

Now I am debugging successfully. I can debug either on the Visual Basic end
or I can debug on the C++ side by using the DLL's project file and declaring
the compiled VB code as the launching executable. I have narrowed the problem
down to the way that I am declaring and passiing the string variables.

oooh.

I really have no idea...it SOUNDS like something you'll have to use a wrapper on to pass, although you mihgt can get away with doing some sort of conversion upon reading it instead.

And while this is a horrible answer, you may have some luck trying visual C# as well, as it has all the gui aspects of VB, and has similar power to C++

this is one of the main issues that microsoft has attempted to solve with their .net framework.

the other way is to use symbol resolution and binding to a type that's recognizable by both ends. declare a char array and export it as a public symbol in your dll, and use whatever vb's equivalent to __declspec(dllimport) is to import it into your application.

It would help if you told us what version of C++ and VB you are using.
