Teststand simple UI

[Tonnie]

Hello

I want to use the simple UI (CSharp) from the Teststand 2013 tutorials as a starting point for a new UI. In this new UI i want to sent messages (button press) from the UI to the running sequence and i want to change Fileglobals. How do i do this ?

I menaged to update the UI from my running sequence using message but now i want the other way around. From UI to sequence

Thanks in advance

Hello,

A very simple way of doing this is using StationGloblas. You can access the StationGlobals from the UI using the Engine reference (Globals Property), and programmatically access to property contained in StationGlobals. Drawback, there is no event link between UI and sequences, you have to pool on variables expecting a change, or something like that.

Much less simple, it is also possible to trigger a TestStand Notifier from the UI, using the SyncManager to call the GetNotification method. You can this way get a reference to a named Notification, created in your sequence for instance, wait for this notification in the sequence, and use the SetEx method to trigger an action in the sequence (with optional arguments). This implies to handle timeout, error handling, and others stuffs... 

There is something to think about with this kind of mecanism, is how the sequence behave in development mode, i.e. using the NI Sequence Editor (SeqEdit) if you implement mecanisms specific to your user interface.

Hope this helps...

You're welcome.

In the end, wich mecanism did you use ? StationGlobals or Notifiers ?
