Generally, when running a command, youj can supress its output by directing it to a file, then deleting the file
md5.exe blahblah >null
the >null being the critical part. Note however, that null doesn't directly it to a magical blackhole. It creates a file named null and prints the output there
This would supress the output. IF you posted some code, I could have told you how to do that there. but if you are running it as a shell exec, this should work
You can use the run method to supress the window.
Set WshShell = CreateObject("WScript.Shell")
cmd= "C:\Users\Administrator\desktop\experimenting\md5.exe"
'OR whatvere your whole command is
cmdRun = WshShell.Run(cmd,0,true);
Answer from here Want to hide command prompt window in using WshShell.Exec method (Upvote the guy if you find it useful)
Please note that you have tro use the output file to read. You cannot read the output from the shell anymore.
