Hi iHadi,

my question is

How to exit the screensaver on a movement in mouse ????

I want to capture the mouse movement on the screen and if there is any movement just close the window.

Thanks...

try

private void Form1_MouseMove(object sender, MouseEventArgs e)
{
    Application.Exit();
    // or
    // this.Close();
}

Hi iHadi,

I tried that already...
If i use that, the screensaver is vanishning in less than one second, even if there is no mouse movement and keyboard inputs. :(

by: iHadiPosted on 2009-05-15 at 02:00:13ID: 24393395

try the following:

bool beginDetect;
 
public Form1()
{
    InitializeComponent();
    timer1.Interval = 1000;
    timer1.Start();
}
 
private void Form1_MouseMove(object sender, MouseEventArgs e)
{
    if (beginDetect)
        Application.Exit();
}
 
private void timer1_Tick(object sender, EventArgs e)
{
    beginDetect = true;
    timer1.Stop();
}

Hi iHadi,

I am experiancing the same problem, the screensaver vanishes automatically.
please see the below code.

this.close() - exits the screensaver form.
application.exit() - exits the whole application.

Thanks..

        {
            InitializeComponent();
            timer1.Interval = 1000;
            timer1.Start();
 
            this.FormBorderStyle = FormBorderStyle.None;
            this.WindowState = FormWindowState.Maximized;
            this.Size = new Size(this.Size.Width * 2, this.Size.Height); 
        }

Hi :iHadi,

MouseCaptureChanged event accepts only right clicks and not working for
mouse movements.

by: iHadiPosted on 2009-05-15 at 02:57:38ID: 24393717

Then just ignore it and don't use it. The MouseMove event will be enough. If you are still having the problem, please post your full code or attach the form's files so I can have a look at it.

Hi Hiadi,

Please take a look at the posted code.

        {
            InitializeComponent();
            timer1.Interval = 1000;
            timer1.Start();
 
            this.FormBorderStyle = FormBorderStyle.None;
            this.WindowState = FormWindowState.Maximized;
            this.Size = new Size(this.Size.Width * 2, this.Size.Height); 
        }
 
        private void Screensaver_MouseMove(object sender, MouseEventArgs e)
        {

The code is working great for me. Let me describe what I understand the code should do. When the program is run, the screensaver form appears in maximized state. If the mouse moves or clicks, the form should close. There is a delay of 1 second so the form displays and stabilize before reacting to mouse events.

Did I get everything right or is there any other requirements?

by: burningmacePosted on 2009-05-15 at 03:17:24ID: 24393824

You should create a tollerance for MouseMove. If the movement exceeds n pixels, exit the program.

    Private LastPos As Point = Form.MousePosition
 
    Private Sub frmMain_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Me.MouseMove
        Dim diff As Point = Point.Subtract(LastPos, Form.MousePosition)
        If Math.Abs(diff.X) > 10 Or Math.Abs(diff.Y) > 10 Then
            Application.Exit()
        End If
    End Sub

Hi burningmace,

I am getting the following error if i use ur code...

Error 1 The best overloaded method match for 'System.Drawing.Point.Subtract(System.Drawing.Point, System.Drawing.Size)' has some invalid arguments

Error 2 Argument '2': cannot convert from 'System.Drawing.Point' to 'System.Drawing.Size'

by: srk1982Posted on 2009-05-17 at 18:13:33ID: 24408557

Hi iHadi,

Yes you are right. But when i write the mousemove event, the form is exiting without an mouse movement. wierd is'nt it !!!?

by: srk1982Posted on 2009-05-18 at 01:13:00ID: 24409799

SOMEONE PLEASE HELP ME ON THIS...
ITS URGENT

by: burningmacePosted on 2009-05-18 at 04:10:11ID: 24410799

Sorry, my code was bad. Forgot that the second parameter was a size and not a point. Do it this way:

    Private LastPos As Point = Form.MousePosition
 
    Private Sub frmMain_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Me.MouseMove
	Dim x_diff As Integer = Math.Abs(LastPos.X - Form.MousePosition.X)
	Dim y_diff As Integer = Math.Abs(LastPos.Y - Form.MousePosition.Y)
        If x_diff > 10 Or y_diff > 10 Then
            Application.Exit()
        End If
    End Sub
