Danke

Hallo,
"RefNum" itself is an integer, but it means many different things. It could be the pointer to a data structure or it could be simply just an internal number created by NI for certain functions. You get "RefNum" when you open a file, or create a queue etc. Different way created "RefNum" should not be used mixed, for example you can not use the RefNum that you get from opening a file to pass into a queue vi. What exactly do you want to do?

Hello,

For creating a RefNum from a c++.net dll it only works with the constructur node, or is there another posibility?
