How to Run DOS Commands in VB.Net


The VB.NET "System.Diagnostics.Process" class contains the functions and properties needed to send console commands to the Windows MS-DOS command line utility. You use MS-DOS commands in VB.NET applications that run in the console. These applications change settings on a computer, fix driver issues or check the directory for missing system files.

  • Click the Windows "Start" button and type "visual studio." Press "Enter" to open the VB.NET programming software.

  • Open the VB.NET project file. After the project file loads, double-click the code file you want to use to send commands to the console.

  • Add the following library file to the top of the VB.NET code file:

    imports System.Diagnostics.Process;

    This library class file imports all of the necessary functions to call the console commands.

  • Type the following code to send commands to the DOS prompt:

    Process proc = Process.Start();

    p.StandardInput.WriteLine(@"cd windows");

    This is the "change directory" command. It changes the command prompt focus to the "windows" directory. You can use any command in the "WriteLine" function to send to the prompt.
