Hi guys,
I am using C++ dll to control a frame grabber. Everything works fine in my C++ applications using the dll in VS2017.
Then I created a VI wrapper using Call Library Function Node to the dll. However, when I try to use the wrapper VI to control the frame grabber, the function inside the dll says there is no connected frame grabber, with no syntax error. It is really strange because it successfully finds the device using exactly the same function in the dll in VS but in LabVIEW it doesn't.
I wonder if LabVIEW needs additional driver to talk to instruments inside C/C++ dll whose driver is already installed on Windows.
Could anybody help me on this?
