string does not update in state machine

[James_W]

Help

I'm pulling my hair out over this one.

I have a string control I want to get the value this from the front panel at a certain point in a state machine type architecture, but the value held in the string by LabVIEW does not get updated during program run time for the purposes of the block diagram.

I have verified the VI is not corrupt by creating this simple VI to demonstrate what I am trying to do. (other case empty)

Neither the string length nor the indicator linked to the local variable, nor a probe on a wire connected to the string get updated if during the 2 secs after starting the VI something is typed in the string control.

LabVIEW version 2009

OS Windows 7

Could this be and OS related issue? - I normally use XP not Windows 7 with 2009 and I've never noticed this before.

Any fast feedback over the weekend would be greatly appreciated

Thanks

James

Try to set the string control to "update value while typing". (right-click...).
