[2008] Resize and center from on primary screen

Depending on end users primary screen resolution, I size my form.

Code:

---

Me.Size = New System.Drawing.Size((workingRectangle.Width - 200), (workingRectangle.Height - 200))

---

After resizing I would like to center the form on the primary screen

Please can someone show me how to do this ?

Me.StartPosition = FormStartPosition.CenterScreen does not center it.

Answering my own question:

vb Code:

Imports System.Windows.Forms.Screen

Code:

---

            ' Retrieve the working rectangle from the Screen class
            ' using the PrimaryScreen and the WorkingArea properties.
            Dim workingRectangle As System.Drawing.Rectangle = Screen.PrimaryScreen.WorkingArea
            ' Set the size of the form slightly less than size of
            ' working rectangle.
            Me.Size = New System.Drawing.Size((workingRectangle.Width - 200), (workingRectangle.Height - 200))
            ' Set the location so the entire form is visible.
            '      Me.Location = New System.Drawing.Point(5, 5)

            Dim allScreens As Screen() = Screen.AllScreens
            Dim currentScreen As Screen = Screen.FromControl(Me)
            Dim currentIndex As Integer = Array.IndexOf(allScreens, currentScreen)

            Dim PrimaryScreen As Screen = allScreens(0)

            ' This is the area of the screen the form can use: total bounds minus any
            ' toolbars, taskbar, etc.
            Dim newBounds As Rectangle = PrimaryScreen.WorkingArea

            Dim centerPoint = New Point((newBounds.Width - Me.Width) \ 2, (newBounds.Height - Me.Height) \ 2)

            ' Now, we adjust to global coordinates by adding the new screen's location
            Dim finalPoint As Point = New Point(centerPoint.X + newBounds.X, centerPoint.Y + newBounds.Y)

            ' Move the form
            Me.Location = finalPoint
