show panel from dll in Test Stand

[steve h]

I have created a LabView dll that I call from TestStand, this passes parameters ok. However I want the LabView panel within the dll to be shown when it is called; how can this be achieved?

Hi steve h,

it should be possible if you implement the "show front panel" into your dll code.

Hope it helps.

I would like to think so; but how can this be done?

Hi steve h,

insert a property node with "show front panel" inside the vi which you export as function. Connect a true to it and it should work. Who did you try it til now?

I have not used (or needed) property nodes before and have just been passing parameters between LabView & TestStand using the standard dll parameter list; this works ok but I need to see the LabView panel in this case. 

Can you give me more detail on how you achieve this property node within the LabView dll?

No need for property nodes or anything else complicated. You do most of the work in the VI Properties>Window Appearance>Customize. At the very least, you want to check the 'Show front panel when called' and 'Close afterwards if originally closed'. When I make a custom edit step, I usually just select the 'Dialog' option on the Window Appearance screen. You should also make a modification to the VI. Add the TestStand - Start Modal Dialog as the very first thing and use TestStand - End Modal Dialog as the very last operation in the VI. You'll have to add the sequence context control and pass this to the dll.

Great, thanks for that.
