System Exec with MSC File

[OrangeAndGreen]

Hi to all,

I'm trying to launch the Disk Defragmenter (C:\WINDOWS\system32\dfrg.msc) from LabView, but via several attempts I have only gotten the Windows error 193 (invalid Win32 application) or a floating command (DOS) window. Here is a summary of the inputs and results for System Exec for the tests I've tried:

Command Directory StdIn Result

dfrg.msc . (blank) Error 193

"C:\WINDOWS\system32\dfrg.msc" . (blank) Error 193

cmd . dfrg.msc Command window in current VI directory

cmd C:\WINDOWS\system32 dfrg.msc Command window in system32 directory

If I run either of the first two Command values using the Windows "Run..." the Defragmenter is launched.

Does anyone have any suggestions? I'd really appreciate the help!

By the way, for those who replied to my post in March about preparing for the CLD (incidentally, it disappeared from the LAVA forum), I passed with flying colors and am proud to now call myself a Certified LabView Developer! Thanks again for the studying tips.

Nevermind, I figured out a solution while playing around. For those who are curious, I created the following batch (.bat) file:

C:\WINDOWS\system32\dfrg.msc

exit

Calling the batch file with System Exec successfully launches the Defragmenter.

I guess I was too eager to ask for help!

The following should work without the need for a batch file......

Indeed, that works without the use of a batch file. Thanks for the tip!
