Hi all
I run a batch file which runs the same application numerous times with variable parameters
between each run it requires any key to be presses
How do i mimic the space bar hit in the cmd line?

the batch file looks like this:

c:
cd "C:\My App"
"C:\MyApp\MyApp.exe" "1"
"C:\MyApp\MyApp.exe" "5"
"C:\MyApp\MyApp.exe" "0"


between the "C:\MyApp\MyApp.exe" "1" and the "C:\MyApp\MyApp.exe" "5"
the cmd line waits for any key press from the user.
so i want to write this key press in the cmd line
somtheing like:

c:
cd "C:\My App"
"C:\MyApp\MyApp.exe" "1"
"PressKey" {"SpaceBar"}
"C:\MyApp\MyApp.exe" "5"
"PressKey" {"SpaceBar"}
"C:\MyApp\MyApp.exe" "0"

Thanks!
