[sridharavijay]

GetCursorPos api

just an example from api-guide:

'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

OOPs!!! Too much...Any ways thank you
this worked out for me
Private Type POINTAPI
x As Long
y As Long
End Type
Private Declare Function GetCursorPos Lib "user32" (lpPoint As POINTAPI) As Long
