Question about calling batch file by using the System Exec+.vi?

[Bill Choy]

Hi

I have a problem about calling batch file. I know that the system exec is equivalent to "run" in Windows. I called the batch file c:\rtxdos\bs\ch0.bat successfully in the "run" but it didn't work in the LabVIEW program. The dos prompt had an error message "Bad command or file name" and it just happen when I call this batch file in LabVIEW. Why?

Bill.

Hi,

Try to set the "working directory" parameter of System exec.vi to the directory where the batch file is located. It may help.

Good luck.
