Nightscream is on a distinguished road

  Old  [VB.NET]Mouse click(coords problems)

What i want to acomplish, to find the coordinates of my screen so like upper left corner is 0,0 but i'm getting proble with it, I want to use the SetCursorPos function later wit the coords that are recorded
I'm using the GetCursorPos function to get the coords
But when i want to see the x and y coords i get something very strange.
x = 1155346203274
y = 0
Now i want to know how can i get this fixed? :s

Code:
Structure PointApi
	Dim x As Long
	Dim y As Long
End Structure

Declare Function GetCursorPos Lib "User32" ( _
		ByRef lpPoint As PointApi) As Long

Private Sub btnPosition_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnPosition.Click
Dim pt32 As PointApi

GetCursorPos(pt32)

txtX.Text = pt32.x
txtY.Text = pt32.y

Is this for your winapp?

Before I give you the code, have you looked at MSDN?
Also I would recommend using the .net functions for mouse input.

Yes it's for my winxp, it should be an auto clicker so i can open up some things and let them scan with just hit a start button.
I'm kind of new to vb.net
I think this fuction is good http://msdn2.microsoft.com/en-us/library/ms645607.aspx

After looking that over I think that is C++ code.

OH SORRY! I gave you the wrong class, here

http://msdn2.microsoft.com/en-us/lib...or(VS.71).aspx

its the CURSOR CLASS.

look in the properties and you'll find , cursor.position

       'get the cursor handle
        Me.Cursor = New Cursor(Cursor.Current.Handle)
        Cursor.Position = New Point(Convert.ToInt32(txtX.text), Convert.ToInt32(txty.text))
        

    End Sub
End Class
try using the framework as much as possible. api is good but use it when its absolutely neccessary.
