Hey i have some trouble send and receiving strings from a dll build in
labview. I use the CStr pointer has anyone an example written in Visual C++
that access the Strings from a Labview dll

To call a LabVIEW DLL from C you should tell LabVIEW to pass the string as a C string. Do not use LabVIEW strings, as there is no easy way for the caller of the DLL to properly create a LabVIEW string to be passed into the DLL.

i only see 3 ways to pass a string in the define prototype dialog.

string handle pointer
Cstring pointer
Pascal string pointer

Could any just tell me how to pass astring to a labview dll from MFC with
just one of these methods

regards Esben
