Problem with Call Library Function. Want to pass a string and return a string, but my compiler does not recognize "CStr" and Labview does not recognize my "char *function()" callout

Hi, I'm trying to use a .DLL I wrote in Visual C++ .NET. The Call Library Function generates a function prototype of "CStr Parser(CStr arg_raw)"
but my compiler won't accept this. So I change it to how C normally deals with strings "char *Parser(char *arg_raw). Now the Call Librafy Function does not find "Parser" in my .DLL though it is definitely there!

Help!

Hello

You will need to include extcode.h in your C file. You can find this under ..\LabVIEW\cintools folder.
The include has all the defines you will need.

Hm, I don't have this folder in my directory. I'm running Labview 6.1, base dev. Do I need full dev for this?

Looks like you would need the full dev for these headers and lib's. Would explain why you dont have the cintools folder.
