Compaq Visual DLL Does not work. Why?

Hello there,

 

The attached LV VI is meant to use a DLL made by CVF. But the output is always zero. Can anybody explain why please?

 

The fortran code is inserted in the VI. The DLL is in the zip file.

 

Thanks

Amir,

 

There's several discussion forums already on getting a Compaq Visual DLL to work with the Call Library Function in LabVIEW.

My fortran was before my time of education, so I don't know the specifics of the data types and how it handles pointers. Here's an article on using the Call Library Function.
