LabVIEW not running when "Display user message" appears. Is there away around this?

[Ryan Siefring]

Hello,

I'm currently building a state machine that identifies failures in compressors.  I've made a message box appear when it detects a compressor failure, but I’m running four test stands.  Which means I have four test stands in one loop.

  When this event occurs, LabVIEW freezes and waits until the User has hit the Ok, button.   I would like the program to continue to run while the text box appears or at least start back up rather quickly once it appears.   Is there any way to do this, because I have no clue?  Thank you for your help, or even at least reading this.

Regards,

Ryan

The easiest thing to do would be to not use the dialog box at all. If it's just to display a failure message, you can have a string indicator/listbox/table on the front panel for your status display. If the user doesn't have to do anything when a failure occurs, you really don't need a pop-up with an OK button that needs to be clicked.

Thank you for your help Dennis

Ok, yeah, you are correct.  The user does not need to do anything when a failure occurs.  I was just doing it to prompt the user so that they know that a Failure has occurred and what to do about it.  I guess this information will just need to be placed into the user manual.

Both of these are bad options from a user interface point of view. You can use a call by reference node to open up a custom-designed window (really a vi front panel) that gives the user the information AND you can keep data collection going on in the background.

Use attached VI with the IsAsync? input set to True if you need to display a message box without freezing the execution of the code.
