What I have tried:

Dim mve as integer

Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load, RefreshToolStripMenuItem.Click

    Form1.Location = New Point(SystemInformation.WorkingArea.Right - (Form1.Width), SystemInformation.WorkingArea.Bottom )

end sub


Private Sub Timer2_Tick(sender As Object, e As EventArgs) Handles Timer2.Tick    
    mve = mve + 1            

        If mve = 100 Then
        End If

    Me.Location = New Point(Me.Location.X, Me.Top - 10)

end sub

Most likely because Me.Top is changing as you move the Form. Try capturing the X and Y positions when you load the form and then adjust and use those values each time you reposition the form.

thank you Richard,
ive try to capturing the (X,Y positions) in form load
mycrntpstn = me.location.y
Me.Location = New Point(Me.Location.X, mycrntpstn - 10)

but the result still as it :(

the main problem is: the start up position always is same when run the app, so why every run will got a different result ?

You need to adjust the value of mycrntpstn each time. If it continues to fail then you need to log the values each time so you can see where it is going wrong.

Form1.AutoScaleDimensions = New System.Drawing.SizeF(96.0!, 96.0!)
Form1.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Dpi
