How to run command line in LABVIEW 7.1

[XiaCHEN]

Dear Sir/Madam,

I want to execute such as command like this:

c:\data\rename aa.txt aa.hex

In LABVIEW 7.1, how do we implement this command. I really appreciate your help on this matter.

Regards,

Xia

Use the sys exec function.  In LV 7.1 it is in the Communications palette.

I was assuming this was a command line exe for renaming?

Thanks for your message. I have tried sys exe in communication palatte. But it gives me error. I am not sure what is wrong.

Actually, in windows environment, I click the "Start" Button and run "cmd". Dos environment opens and then use the command Rename test.txt test.hex

I appreciate more help on this matter.

Can you send me the program you write so that I can compare?

Thank you!

I realize this isn't a direct answer to your question, but if you are trying to rename a file, why don't you use the move function in the Advanced File Functions palette?

You may need to use the following coomand line for system exec:

cmd.exe /c c:\data\rename aa.txt aa.hex
