Run CMD command without displaying it?

Question

I have created a Process to run command in CMD.

var process = Process.Start(\"CMD.exe\", \"/c apktool d app.apk\");
process.WaitForExit();

How

Answer 1

There are several issues with your program, as pointed out in the various comments and answers. I tried to address all of them here.

ProcessStartInfo psi = new ProcessStartInfo();
psi.FileName = "apktool";

//join the arguments with a space, this allows you to set "app.apk" to a variable
psi.Arguments = String.Join(" ", "d", "app.apk");

//leave it to the application, not the OS to launch the file
psi.UseShellExecute = false;

//choose to not create a window
psi.CreateNoWindow = true;

//set the window's style to 'hidden'
psi.WindowStyle = ProcessWindowStyle.Hidden;

var proc = new Process();
proc.StartInfo = psi;
proc.Start();
proc.WaitForExit();

The main issues:

• using cmd /c when not necessary
• starting the app without setting the properties for hiding it

Answer 2

Try this :

     proc.StartInfo.CreateNoWindow = true;
     proc.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
     proc.WaitForExit(); 

Answer 3

ProcessStartInfo startInfo = new ProcessStartInfo();
startInfo.CreateNoWindow = true;
startInfo.UseShellExecute = false;
startInfo.FileName = "dcm2jpg.exe";
startInfo.WindowStyle = ProcessWindowStyle.Hidden;
startInfo.Arguments = "-f j -o \"" + ex1 + "\" -z 1.0 -s y " + ex2;

You can use the WindowsStyle-Property to indicate whether the process is started in a window that is maximized, minimized, normal (neither maximized nor minimized), or not visible

process.StartInfo.WindowStyle = ProcessWindowStyle.Hidden

Source: Property:MSDN Enumartion: MSDN

And change your code to this, becaeuse you started the process when initializing the object, so the properties (who got set after starting the process) won't be recognized.

Process proc = new Process();
proc.StartInfo.FileName = "CMD.exe";
proc.StartInfo.Arguments = "/c apktool d app.apk";
proc.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
proc.Start();
proc.WaitForExit();
