Taking a screenshot in VB.Net

Taking a screenshot from a .Net app is very easy. The function to use is the CopyFromScreen function from the Graphics class.


        Dim b As Bitmap

        'Hide the form, so it doesn't show in the screenshot
        Me.Hide()

        b = New Bitmap(My.Computer.Screen.WorkingArea.Width, _
                My.Computer.Screen.WorkingArea.Height, _
                Imaging.PixelFormat.Format32bppArgb)
        Dim g As Graphics = Graphics.FromImage(b)
        g.CopyFromScreen(New Point(0, 0), New Point(0, 0), _
                New Size(My.Computer.Screen.WorkingArea.Width, _
                 My.Computer.Screen.WorkingArea.Height))


        'Show the form again
        Me.Show()

        'Save the file
        Dim ofd As New SaveFileDialog ()
        ofd.Filter = "(*.bmp)|*.bmp"
        If ofd.ShowDialog() = Windows.Forms.DialogResult.OK Then
            b.Save(ofd.FileName)
        End If
