CString to char*

[Jaredino]

Hi,
I have read lots of posts on this but still can't come up with any answers. I have a CString named 'm_sResults1' that needs to be passed to a function named 'openWavFile()' that expects a char*. How do I convert a CString to a char*??

IIR right, chars can be either bytes or fixed length strings. I think the * means that it's a pointer?
When dimming CString do it in the format
dim Cstring as string * 8
Making it an 8 character fixed length as an example. I can't say exactly how long that string should be though.

Pass by reference.

Thanks for your quick replies but I'm new to programming so unfortunately I don't know what either 'dimming' or 'passing by reference' is! Is there not just a line of code that can assign a CString object to whatever the pointer is pointing at?

Did you write a declaration for this function openWavFile ??? Or is it part of a COM object that you are using? ... how are you going to call it?

 

[Jaredino]

Yes, the declaration for the function is:

void CWavFile:penWavFile(char* fileName)

The function is called within CWavFile.cpp file
The member variable m_sResults is in a different class

Can we just check that you are in the right forum?

Ooops sorry
Ignore me
I'll go try the right one should I?
Thanks anyway!

Doh! I thought he was just trying to declare a C API function in VB too.
