problem about calling a labview dll from VC 6.0

[soslotos]

I have built a dll in labview 7.1
I want to call the dll from VC 6.0.
The function I called from VC 6.0 didn't work at all,but the vi could generate two pluses in the labview.
The attachment is my vi

Regards soslotos
Thank you

I built a dll for the Generate Single Pulse(DAQ-STC).vi,and called it from the VC 6.0.
it doesn't work,either.
I find the vc could only call the easy function create by labview.

Hello Soslotos,

I am assuming you built the VI using traditional DAQ. With Traditional DAQ, building a DLL from LabVIEW does not guaranty that you can successfuly call if from another programing environment. If you want to be able to do this, you need to use DAQmx instead.
