How to read system root from registry

[frogfrog]

Hi all,

I read system temp from registry, and it gives me "%SystemRoot%\TEMP".  Then where can I get system root then?

thanks for any help.

What about  Get System Directory VI for the system directory (or Temporary Directory Function for the temporary directory)?

[ergwser]

 Temporary Directory Function returns user temp path, not system temp.

I am using Labview 8.5, couldn't find Get System Directory VI .

Thanks.

 You can use either System Exec or call the ExpandEnvironmentStrings function in the Windows API. See attached example (LV 8.2)
