.NET / WinForms: enlarge a window on a specific screen

Question

I have a dual monitor setup, and I want my C # application to maximize its window on a particular screen.

How can i do this?

thanks!

Answer 1

You can make this work by moving the window all the way to the right or left to maximize. This should cause the window to maximize on this screen when it is maximized.

Answer 2

This is a screen control code for a similar area in one of my projects:

        // screenId in my case is 1(first) or 2(second)
        int screenId = RegistryManager.ScreenId;
        // DualScreen management            
        if (screenId > 0)
        {
            // Have 2 screens
            if (System.Windows.Forms.Screen.AllScreens.Length == 2)
            {
                if (screenId == 1) // first
                    this.Location = new System.Drawing.Point(System.Windows.Forms.Screen.AllScreens[0].Bounds.Left, 0);
                else // second
                    this.Location = new System.Drawing.Point(System.Windows.Forms.Screen.AllScreens[1].Bounds.Left, 0);
            }
        }

Screen

Code found here

function void showOnMonitor2()
{
Screen[] sc;
sc = Screen.AllScreens;
//get all the screen width and heights
Form2 f = new Form2();
f.FormBorderStyle = FormBorderStyle.None;
f.Left = sc[1].Bounds.Width;
f.Top = sc[1].Bounds.Height;
f.StartPosition = FormStartPosition.Manual;
f.Location = sc[1].Bounds.Location;
Point p = new Point(sc[1].Bounds.Location.X, sc[1].Bounds.Location.Y);
f.Location = p;
f.WindowState = FormWindowState.Maximized;
f.Show();
}

  Public Shared Sub MoveForm(Item As Form, ScreenNumber As Integer, Optional X As Integer = 0, Optional Y As Integer = 0)
    With Screen.AllScreens(ScreenNumber).Bounds
      X -= .Left 'translate overall coordinates to screen coordinates
      Y -= .Top
    End With
    Item.Location = New System.Drawing.Point(X, Y)
  End Sub
