Add CallBack Error

[hlim]

Hello everyone,

I am modifying the simple user interface (<TestStand Public>/UserInterfaces/simple/LabVIEW/SourceCode/...) provided in the test stand 2014 (32 bits) version and encouter a problem. Below is what I did:

1. Opened the Top Level VI.vi, in 'Register Event Callbacks' case, I extended another block to try to add a callback.

2. I wired in the Application manager, select the 'EndExecution' event.

3. Wire in the UIDATA into the 'User Parameter'.

4. Right click the VI Ref and create a call back. See blockdiag1.jpeg.

5. Open the call back and saw an error in the UIDATA input. See FrontPanel1.jpeg.

Can anyone please tell me why the error in the UIDATA input? The error says that it either cannot find the master copy of UIDATA

or there is error in the master copy. Any idea how to overcome this error?

Thanks.

Yours,

HLim

Hello hlim,

to fix this, replace the control with control inside the LLB

Hope it helps

Hello Alexander Glasner,

Thank you very much for the pointer, it works. I wonder why the error in the first place though.

I am learning something new about TS/LV everyday!
