Calling SubVI's recursively !

[q123456789]

Hello Everyone,

I'm trying to write a program which should have 5 panels; Main panel, Sub-main, Setting panel, and two Sub-panels. From the main panel, I should be able to call the sub-main and setting panels. Once I am in the sub-main panel I should be also able to go to the other sub-panels recusively. The problem is when I call one of the sub-panels, and try to go back to the Sub-main panel, it goes to the Main panel, instead, and stuck there because the sub-main is still running!

For calling the subVI I'm using a "case sturcture" inside wich I put the SubVI and set the "SubVI node Setup" to:

"Show Front Panel when Called"

I feel my explanation is a bit cofusing , but hope some one can give me some hints to solve this problem.

Cheers !

Mike

Hello,

To get an answer here, you should include a minimum example VI showing what you are doing.

You have to make any VI's that you try to call from more than one location Reentrant. Hit Ctrl + I (VI Properties) go to the Execution Category and hook off "Reentrant Execution". If you don't., you will have a deadlock if the VI is called from two or more places at the same time.
