Window form isn't in the top left corner

Hello
I have a WindowsForms Application with the main window Form1 . Form1 has the Size 1280x1024 and should cover the complete Screen (Windows Taskbar must be hidden)

But somehow I can't paint the Window on the top of the monitor. The whole application has like an offset from around 30 pixels on the top and from around 10 pixels on the left. That gives me a gap on the top and on the left where I still can see the desktop.

This is how I located the Form1 :

namespace MainWindowLocation
{
  public partial class Form1 : Form
  {
    public Form1()
    {
      InitializeComponent();

      this.Top = 0;
      this.Left = 0;

    }
  }
}

I work with VS2010 on Windows 7.

What can I do tho locate my Form 100% in the monitor?

the reason my solution did not include setting window state maximised was becuase the question states that the task bar must be hidden. if the use does not have auto hide turned on it would still be visible when maximised.

The following code sample should do the job for you.

Hope that helps

this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.FixedToolWindow;
            this.Width = System.Windows.Forms.Screen.PrimaryScreen.Bounds.Width;
            this.Height = System.Windows.Forms.Screen.PrimaryScreen.Bounds.Height;
            this.TopMost = true;
            this.StartPosition = FormStartPosition.CenterScreen;

Open in new window

Apologies, you probably want FormBorderStyle.None

Why not just set the WindowState property of your form to Maximized?
