How to Minimise other windows while your application is running C#

Question

I need to minimize all other windows while my application is running. Is there a better way to do it using APIs?

Answer 1

Use the following class and Call the method MinimizeAll(); to do it.

Try this code:

using System;  
using System.Runtime.InteropServices;

public class WindowMinimize
{

    const int SW_SHOWMINNOACTIVE = 7;
    // Hide other windows


    [DllImport("user32.dll")]
    static extern bool ShowWindow(IntPtr hWnd, int nCmdShow);

    static void MinimizeWindow(IntPtr handle)
    {
        ShowWindow(handle, SW_SHOWMINNOACTIVE);
    }


    public static void MinimizeAll()
    {
        System.Diagnostics.Process thisProcess =
           System.Diagnostics.Process.GetCurrentProcess();
        System.Diagnostics.Process[] processes =
           System.Diagnostics.Process.GetProcesses();
        try
        {
            foreach (System.Diagnostics.Process process in processes)
            {
                if (process == thisProcess) continue;
                System.IntPtr handle = process.MainWindowHandle;
                if (handle == System.IntPtr.Zero) continue;
                MinimizeWindow(handle);
            } //loop
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.Message.ToString());
        }
    } 
}
