I have some dll's for a frame grabber card that I need to access from
LabVIEW (a graphical programming environment). LabVIEW can call win32 dll's and can handle many different datatypes - my problem is that I have not been successful at passing in handles to the dll. So what I thought I would do was wrap the dll inside a dll which could handle the translation of the types that LabVIEW supports to the data types needed by the frame grabber dll's.
Problem is I am not exactly sure how to call a dll from within another dll.
after searching the Internet I found an example program which uses the LoadLibrary and GetProcAddress functions - these look like what I need but I am not clear on how you actually pass parameters into the dll and get data out of it... The code I found was downloaded from
Could someone please provide a clear example of how to do this ?
