close subvi window without "close afterwards when originally closed"

[User002]

Hi everybody,
I've got a problem concerning Labview. In my program I need to update a graph in a seperate window. Therefore I made a subvi to display the data. The problem is now to close the window afterwards. The subvi is inside a while loop to get updated data all the time. I tried to use the "close afterwards when originally closed" but then the graph is closed after every loop. But it should be opened during the loops. I want to close the window manually by sending a false or anything else. Does anyone know an answer to my problem? Please help!!!
Thx
Thomas

You can close the VI's FP by using VI server techniques. Open a reference to the VI (use Open VI reference from the Application Control Palette, do this outside the loop) and wire that reference into a property node. Then, select the FP.Open property, place the node after the loop and wire F into it. When the loop finishes running, the FP will be closed.
