send command instead of typing in

[yuntan]

When a third party software or application is opening, I can type in command/text to its prompt. Anyone knows how do I use LabVIEW to send in the command/text instead of key in? 

I tried with "SendKeys.vi" (e.g., exit \C as shown), but the input to the prompt shows "59~" instead of "exit". (When I send "\C" the application will take the "Enter" and next prompt appears.) Can someone help me? Thank you in advance.

I found the solution after searching around. I can use Keycode to implement my request, see attached.
