Public Shared Function FromPoint (
	point As Point
) As Screen

Parameters

point
Type: System.Drawing.Point

A Point that specifies the location for which to retrieve a Screen.

Return Value

Type: System.Windows.Forms.Screen

A Screen for the display that contains the point. In multiple display environments where no display contains the point, the display closest to the specified point is returned.

The following code example shows how to use the FromPoint method. This example creates a Point referencing the X and Y coordinates passed by a MouseEventArgs, and then uses the FromPoint method to determine if the point clicked is on the primary screen.

Private Sub Form1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles MyBase.MouseDown
    Dim p As New System.Drawing.Point(e.X, e.Y)
    Dim s As System.Windows.Forms.Screen = Screen.FromPoint(p)

    If s.Primary = True Then
        MessageBox.Show("You clicked the primary screen")
    Else
        MessageBox.Show("This isn't the primary screen")
    End If
End Sub
