Form.SetDesktopLocation Method

Sets the location of the form in desktop coordinates.

[Visual Basic]
Public Sub SetDesktopLocation( _
   ByVal x As Integer, _
   ByVal y As Integer _
)
[C#]
public void SetDesktopLocation(
 int x,
 int y
);
[C++]
public: void SetDesktopLocation(
 int x,
 int y
);
[JScript]
public function SetDesktopLocation(
   x : int,
 y : int
);

Parameters

x
The x-coordinate of the form's location.
y
The y-coordinate of the form's location.

Remarks

Desktop coordinates are based on the working area of the screen, which excludes the taskbar. You can use this method to position your form on the desktop. Since desktop coordinates are based on the working area of the form, you can use this method to ensure that your form is completely visible on the desktop. This method is intended to be used primarily for top-level forms; use the LayoutMdi method to position multiple-document interface (MDI) child forms.

Example

[Visual Basic, C#] The following code example demonstrates how to use the SetDesktopLocation, System.Windows.Forms],.Form.Load'/> Closed and Activate members. To run the example, paste the following code in a form called Form1 containing a button called Button1 and two Label controls called Label1 and Label2. Ensure all events are connected to their event-handling methods.

[Visual Basic] 
Shared x As Integer = 200
Shared y As Integer = 200

Private Sub Button1_Click(ByVal sender As System.Object, _
    ByVal e As System.EventArgs) Handles Button1.Click

    ' Create a new Form1 and set its Visible property to true.
    Dim form2 As New Form1
    form2.Visible = True

    ' Set the new form's desktop location so it appears below and 
    ' to the right of the current form.
    form2.SetDesktopLocation(x, y)
    x += 30
    y += 30

    ' Keep the current form active by calling the Activate method.
    Me.Activate()
    Me.Button1.Enabled = False
End Sub



' Updates the label text to reflect the current values of x and y, 
' which was were incremented in the Button1 control's click event.
Private Sub Form1_Activated(ByVal sender As Object, _
    ByVal e As System.EventArgs) Handles MyBase.Activated
    Label1.Text = "x: " & x & " y: " & y
    Label2.Text = "Number of forms currently open: " & count
End Sub

Shared count As Integer = 0

Private Sub Form1_Closed(ByVal sender As Object, _
    ByVal e As System.EventArgs) Handles MyBase.Closed
    count -= 1
End Sub

Private Sub Form1_Load(ByVal sender As Object, _
    ByVal e As System.EventArgs) Handles MyBase.Load
    count += 1
End Sub

[C#] 
static int x = 200;
static int y = 200;

private void Button1_Click(System.Object sender, 
    System.EventArgs e)
{
    // Create a new Form1 and set its Visible property to true.
    Form1 form2 = new Form1();
    form2.Visible = true;

    // Set the new form's desktop location so it  
    // appears below and to the right of the current form.
    form2.SetDesktopLocation(x, y);
    x += 30;
    y += 30;

    // Keep the current form active by calling the Activate
    // method.
    this.Activate();
    this.Button1.Enabled = false;
}



// Updates the label text to reflect the current values of x 
// and y, which was were incremented in the Button1 control's 
// click event.
private void Form1_Activated(object sender, System.EventArgs e)
{
    Label1.Text = "x: "+x+" y: "+y;
    Label2.Text = "Number of forms currently open: "+count;
}

static int count = 0;

private void Form1_Closed(object sender, System.EventArgs e)
{
    count -= 1;
}

private void Form1_Load(object sender, System.EventArgs e)
{
    count += 1;
}
