Halt script with labview

Question

let's say I execute a script using the "diadem run script.vi" due to user request.  Later, the user wants to cancel because it was taking longer than expected.
How do i halt the script using labview tools?

Hi Jim,
This is possible, but not in the way I believe you are hoping.  I know of no way to halt a VBScript running in DIAdem from the "outside".  If you were staring at DIAdem you could hit the <ESC> key, but any subsequent request from LabVIEW will go onto DIAdem's "Script Stack" and will not be executed until the first VBScript is done naturally.
Of course you have to run all your LabVIEW calls to DAdem asynchronously, or nothing helps.
So what you can do is set up each VBScript that you think you might want to abort to periodically poll a DIAdem global variable, say "B9", and terminate from inside the VBScript if B9=TRUE.  The command interface from LabVIEW to DIAdem (ToCommand) goes onto the DIAdem Script Stack, but the variable interface from LabVIEW to DIAdem (ToDataSheet) does not.  So you can "poke" variable B9 from LabVIEW while the first VBScript is running and affect it's behavior, but only if and when that VBScript uses that (B9) variable you poked.
Of course none of this helps if your VBScript is busy waiting for a single VBScript command to execute, and it only helps if your VBScript is running multiple activities, between which it can poll the (B9) variable.
Hope that helps,
