Simple Gui Start Button

[morngoose]

I'm using the TestStand 2010 simple gui, (Labview).

Problem I have with it is that it allows you to press the "Start Test" button multiple times, creating a instance of the test seq each time the button is pressed.

This causes a big problem for my system.

Is there anyway to disable the "Start Test" button after it has been pressed once, or only to allow one instance of the sequence to run ?

Thanks

You just have to register StartExecution and End Execution events in Configure Event Callbacks.vi

Pass your button references as User Parameters and in the former disable them and enable them back (using property nodes) in the latter and voila you are done.

Thanks for the reply!

What VI-REF the start and EndExecution are linked to ? (I've tried them all!)

You need to right click on the node and select Create Callback VI.

Thanks for the help, spent over 3 hours on this today but can't get it working.

All these callbacks and events is new territory for me .....

No worries. Here is the project saved in LabVIEW version 8.0.

Hope that helps.

Can't seem to open the VI in Labview 2011, keeps crashing.

Sorry to be a pain, would you mind attaching a screenshot of the main VI ?

Thank you so much!!

Thanks a ~ton~ .aCe. !! 

I will add one caveat that threw me off for a while: 

 When creating the Callbacks you have to wire the user parameter FIRST before creating the Callback VI or the VI Ref will be broken. 

Thanks again
