UI Message from LV Step to LV UserInterface

[阿辉001]

 I need to post the UI message From LV step to LV UserInterface.But now every step must have a "ThisContext" input from TS Sequence to get the Thread, then post UI message. Is there anyway to input a context only one time?

ThisContext might change during execution and hence the best way is to get it for every step. It would not be robust if you get it once and store it in LV globals.

Alternatively, you can output the message from the LV step and in the PostExpression you can send the UI message, this way you don't need to edit the VI.
