Scan string for computer user name

[Tyler_C]

Good morning NI Forums,

I need direction on a file path scan. I'm trying to get to the user name on any system, primarily XP or 7. I'd like to compare the user name from the "Get System Directory" VI with a constant user name.This way I can pass that to a case structure and close LabVIEW if the computer is logged into the wrong user (there are network read/write permissions which is why I need to control where the program isrun from). Any suggestions for the format string constant or maybe a better mouse trap?

I've attached my VI for reference.

Thanks!

Hi,

We just discussed this on the phone but I am posting the solution so that others are aware of the solution. You wanted to check if a known username is the current user of the system (on XP or Windows 7) so we worked up a quick VI

I don't have LV2011.

Have you seen this Knowledgebase article?

Phillip,

I hadn't seen that article. I didn't realize a property node could grab the user name. Thanks for the post!

Here is updated VI with format string constant and little bit changes in the VI.

Hopefully should work as you are expecting.
