[bob323]

Any idea how to tell the mouse to move to a specific location on the screen?

You should use the SetcursorPos() API:

[code]
'This project needs
'a Form, called 'Form1'
'a Picture Box, called 'ExplButton' (50x50 pixels)
'a Picture Box with an icon in it, called 'picIcon'
'two timers (Timer1 and Timer2), both with interval 100
'Button, called 'Command1'
'In general section
Private Type RECT
Left As Long
Top As Long
Right As Long
Bottom As Long
End Type
Private Type POINTAPI
X As Long
Y As Long
End Type

'Declare the API-Functions

Dim Clr1 As Long, Clr2 As Long
If Pushed = True Then
'If Pushed=True then clr1=Dark Gray
Clr1 = &H808080
'If Pushed=True then clr1=White
Clr2 = &HFFFFFF
ElseIf Pushed = False Then
'If Pushed=True then clr1=White
Clr1 = &HFFFFFF
'If Pushed=True then clr1=Dark Gray
Clr2 = &H808080
End If

With Form1.ExplButton
' Draw the button
Form1.ExplButton.Line (0, 0)-(.ScaleWidth, 0), Clr1
Form1.ExplButton.Line (0, 0)-(0, .ScaleHeight), Clr1
Form1.ExplButton.Line (.ScaleWidth - 1, .ScaleHeight - 1)-(.ScaleWidth - 1, 0), Clr2

End Sub

' If you set Stretched to true then stretch the icon to te Height and Width of the button
' If Stretched=False, the icon will be centered
Stretched = False

If Stretched = True Then
' Stretch the Icon
ExplButton.PaintPicture picIcon.Picture, 1, 1, ExplButton.ScaleWidth - 2, ExplButton.ScaleHeight - 2
ElseIf Stretched = False Then
' Center the picture of the icon
ExplButton.PaintPicture picIcon.Picture, (ExplButton.ScaleWidth - picIcon.ScaleWidth) / 2, (ExplButton.ScaleHeight - picIcon.ScaleHeight) / 2
End If
' Set icon as picture
ExplButton.Picture = ExplButton.Image
End Sub
Private Sub Timer1_Timer()
Dim Rec As RECT, Point As POINTAPI
' Get Left, Right, Top and Bottom of Form1

' Get the position of the cursor
GetCursorPos Point

' If the cursor is located above the form then

I use mouse_event instead of setcursorpos, because you can use absolute values with mouse_event. That means that your app still moves the cursor to the same point when you change your resolution.

Here's a simple example using SetCursorPos.

Private Declare Function SetCursorPos Lib "user32" (ByVal x As Long, ByVal y As Long) As Long

Private Sub Command1_Click()
SetCursorPos 100, 100
End Sub
