How can a Labview VI be run as a background task through an ActiveX call ? (without keeping ActiveX busy)

Question

I would like to execute a Labview VI through ActiveX in Matlab.

I use the following commands:

e=actxserver(\'LabVIEW.Application\');
vipath=\'C:\\DATA\\L         


        

Answer 1

You can either:

• Launch LabVIEW.exe as a process, specifying VI as argument (search help for this). There is for sure a way to tell Matlab to not wait for end of process execution
• Run the VI dynamically, using VI server, inside a launcher VI, and have Matlab call the launcher VI. The latter will return immediately after calling your VI, and Matlab will not wait for your main VI to end.
