Is there a possibility to check if a reference to an activeX-Object ist null refnum and return a boolean?
I have the following problem.
I need to open a reference to an activeX-class. before I do this, i need to check if there is already a reference to this object is open. if there's one i have to close this before a open a new one, because if Labview opens a second instance a have some problems.
I can not just close the reference before I open the new one, because when I start my application an first try to close the reference before I have opened it, I will get an error. So I have to check if there's an opened one.
Hope somebody can help me!
thx!
