I have an image processing algorithm that I have implemented in LabVIEW that needs to be callable from Visual Basic 6. I don't have much experience working with DLL's, but I have managed to make some simple DLL's in LabVIEW that can do basic math operations (e.g., adding two numbers together) and which I successfully called from VB6. Right now, I'm hitting a stumbling block regarding passing a greyscale image to the LabVIEW DLL. What would be the most efficient way of implementing this? Originally, I had planned to pass a two-dimensional array to the DLL, but it seems like passing 2d arrays is tricky after I read this: http://digital.ni.com/public.nsf/allkb/EF28C424B039FA9E86256B6D007D3761?OpenDocument.
Is there a way of loading a picture in VB6 in such a way that the LabVIEW DLL will accept it as a NI-VISA image? Or would reshaping the data into a 1D array and passing that be the best way?
