Hi All !
I created different vi:
Start : open a vi reference, open the Front Panel and start the vi. (return a RefNum).
SetValue : set a value of an indicator on the front panel using the refnum returned by the start.vi
GetValue : get a value of a control in the front panel using a refnum returned by the start.vi
Close : close the reference RefNum.
All these function are integrated in a dll and will be called from a VB . NET software.
My problem is the following: when i call the start.vi severeal times it always return me a different RefNum. In the start vi I don't close the Reference because i need this refNum in the other functions i.e. Setvalue and getvalue. I read different posts and it seems that you always need to close the reference you opened before. But when i call the start vi severeal times, the memory size does not increase, and if i run the close.vi with the last refnum it close the vi properly (i guess).
My questions are : If i open lot of vi references (always on the same vi) does it means that severeal instances of this vi are created ? How can i close all instances opened ?
