for a click in (100, 100)
But the click comes always at the mouse position and not in 100, 100
Why ?
This is a bit more complicated, and it took me a good long while to
figure this out, but here is the solution. You need to do a conversion
of twips per pixel in order to get the correct coordiantes.
Create these two functions in your window or a module:
Private Function twipsperpixelx(x as integer) As integer
dim m as memoryblock
dim i as integer
Declare Function GetDesktopWindow Lib "user32" Alias
"GetDesktopWindow" () As integer
Declare Function ClientToScreen Lib "user32" Alias "ClientToScreen"
(hwnd As integer, lpPoint As ptr) As integer
m = newmemoryBlock(8)
m.long(0) = x
m.long(4) = 0
i = ClientToScreen(GetDesktopWindow(),m)
if i <> 0 then
return m.long(0)
else
return 0
end
End Function
Private Function twipsperpixely(y as integer) As integer
dim m as memoryblock
dim i as integer
Declare Function GetDesktopWindow Lib "user32" Alias
"GetDesktopWindow" () As integer
Declare Function ClientToScreen Lib "user32" Alias "ClientToScreen"
(hwnd As integer, lpPoint As ptr) As integer
m = newmemoryBlock(8)
m.long(0) = 0
m.long(4) = y
i = ClientToScreen(GetDesktopWindow(),m)
if i <> 0 then
return m.long(4)
else
return 0
end
End Function
Then do something like this for your click:
dim x,y as integer
const MOUSEEVENTF_ABSOLUTE = &h8000
const MOUSEEVENTF_MOVE = &h1
const MOUSEEVENTF_LEFTDOWN = &h2
const MOUSEEVENTF_LEFTUP = &h4
const MOUSEEVENTF_RIGHTDOWN = &h8
const MOUSEEVENTF_RIGHTUP = &h10
Declare sub mouse_event Lib "user32" Alias "mouse_event" (dwFlags As
integer, dx As integer, dy As integer, cButtons As integer, dwExtraInfo
As integer)
x = 100
y = 100
x = round(twipsperpixelx(x) * 65535 / screen(0).width)
y = round(twipsperpixely(y) * 65535 / screen(0).height)
mouse_event
bitwisexor(MOUSEEVENTF_MOVE,MOUSEEVENTF_ABSOLUTE),x,y,0,0
mouse_event MOUSEEVENTF_LEFTDOWN,0,0,0,0
mouse_event MOUSEEVENTF_LEFTUP,0,0,0,0
hth,
