Hi,

You can go through the vi which i have attached. Read the explanation from the block diagram of the sub Vi.

You must go through the LabVIEW Basic materials provided with the kit for learning more about creating SubVIs and using them.

Thanks Nitzz

just would u plz help how did u manage to add your subvi icon to the main block diagram.I tried to make another pop up window but I don't know how to select and call my subvi

Hi,

Either you can drag and drop a vi into the block diagram of the main vi in which case the dropped vi will become a subVI automatically, Or you can right click on the block diagram of the main VI and click on "Select a VI" and browse the VI which you want to load as a sub VI.

Hi, 

I can't open the Untitled111.vi as it is in LabVIEW 10 and i have only 2009 version. But i suppose the part you are missing is the VI properties settings. Open the Untitled111.vi, rightclick the vi icon on the upper right side of the front panel, and click on VI Properties.

From the drop down menu of catagory, select Window Appearance.

Then select Custom below and click on customize button.

Another page opens in which select " Show front panel when called " and "close afterwards if originally closed"

Then save the vi and use it in the main vi. When you press the button from the main vi, it will open and start running as needed.

The example was very clean and easy to understand.  I downloaded your example and added a numeric indicator on the mainVI iteration terminal.  It seems the mainVI stops executing when the subVi is called.  This is a problem for me as my mainVI has all of my control logic in it. How can I accomplish exactly what you have done execpt that the subvi is secondary and the mainVI continues to execute?  I have searched the forums thoroughly and have not found any help/examples that fit my needs.  Basically my mainVI needs to continually execute and if a subVI with "show front panel" is called then the front panel shows but does not affect the mainVI execution at all.  Thanks in advance

Hi Trinity32244,

If I understood you correctly, you want to run two VIs simultaneously and also you want one of the VIs to be called from the other. If you follow my example and do this it won't work because, if you place the subVI which runs continuously in a While loop and then call it, the while loop wont get into its next itration untill the SubVI is closed. So its not that the main VI while loop is stopping. Its just that its waiting for the subVI to stop to make its next itration.

To accomplish what you want, I don't think putting the subVI in the same While loop would help. You can make two while loops running in parallel, put all your code into one while loop and the subVI in the other while loop and then call the subVI from the main while loop. In this case both will run simultaneously. I have attached an example which shows how to do it. Download both and run a.vi. Not the best example, but still, I think it will help you.:)

Thanks!!!!!  This was exactly what I was looking for.  This is a much simpler approach then most of the threads that I found previously that seemed to be making a mountain out of a mole hill.  For a newbie in labview this is by far the easiest to follow method of creating a custom pop-up.
