Run CMD Silently

Question

I\'m trying to run CMD silently, but each time I get an error. Could someone please tell me where I\'m going wrong?

Dim myProcess As Process 
myProcess.Start         


        

Answer 1

I suppose your cmdStr is a string with parameters for CMD.
If so you need to use the Arguments property of StartInfo.
You get a Null Exception on the myProcess variable because it is never instatiated with new. You could create a ProcessStartInfo var to use with the static Process.Start method and set the UseShellExecute to False

Dim startInfo As New ProcessStartInfo("CMD.EXE")
startInfo.WindowStyle = ProcessWindowStyle.Hidden     
startInfo.CreateNoWindow = True 
startInfo.UseShellExecute = False
startInfo.Arguments = CmdStr
Process.Start(startInfo)  

or edit your code to add

myProcess = new Process() 

before using the var myProcess
