hi all, i am now developing a activeX system which is let the C++ program to call Labview ActiveX server. However I am really doubt if my approach is correct. So now i develop a very simple activeX system that reading a number in C++ console mode and then C++ call labview reference and pass the number in labview server via VI reference and call method. Can everyone give me some suggestions? (1) for C++ program, i have modified the source node from the code example. I just modify the path of VI and some very basic call. (2) for LabView, i just simply add the indicator and the variant to data function block. also i have enable ActiveX server for that program. However, I didnt do anything ELSE. I am really confused if this approach works. because when i run the exe file from C++, fatal error occur. So can anyone give me suggestion or the specific idea about how to deal with it? thanks for help so much.
"number" is the string "number", not your number variable. You would need to convert number into an asci string using something like sprintf. Or, you can use a VARIANT type.
I couldn't get your simple server to load up, something about a resource not being available. I've been struggling with Labview myself and I was hoping to use yours as a template. If you do have a version that works, please let me know. Thanx.
