stopping a running exe

[jeyanthi]

hi need help.

i have a vi with two button

1. button enable - run the exe automatically

2. button disable-stop/terminate the running exe

i can do the first button(run the exe) but i cant do the second button

i have a vi with two button  <=====  Is this the VI that is the executable? 

1. button enable - run the exe automatically  <=====  Is the executable a LabView VI?

2. button disable-stop/terminate the running exe

i can do the first button(run the exe) but i cant do the second button  <===  ????

I ask because the last sentence makes it sound as if you have a VI that has two button and it is not an executable.  It calls an executable... 

Is that so?

Before suggesting anything, I would need to know what type of executable we are talking about...

Can you provide more description?

Hi Jeyanthi,

Keep the Enable button inside its event case.

Also, change both the button events from Mouse Down to Value Change.

See the modified attachment.

Hi Jeyanthi,

The System Exec VI will run your executable in a separate process from LabVIEW.  LabVIEW by itself cannot kill the process, however, you can use a second System Exec to call a Windows command which will.  See the following link:

Thanks Jeremy,

THis will be quite useful.  Unless there are hooks in the software of Active-X class available for external control, it is difficult to kill a rogue executable..
