How to verify Screen Coords are valid [Resolved]

[ken82m]

I'm reading screen coords from an ini file. They are put their by another script that asks a user to click on certain items.

To verify they are valid I was just going to do a PixelGetColor and look for a -1 if they were invalid.

However using the coords X=9000 Y=9000 The result is 664682.

However my screen resolution is 1024X768.

What am I doing wrong?

Thanks,

Kenny

$DiscTypeX=9000
$DiscTypeY=9000
MsgBox(4096,"Color", PixelGetColor ($DiscTypeX, $DiscTypeY))

if you don't need to work with the color of a pixel, you can check the co-ords against the screen size.

$DiscTypeX=9000
$DiscTypeY=9000
MsgBox(4096,"Color", PixelGetColor ($DiscTypeX, $DiscTypeY))
MsgBox(4096,"Is Inside?",_IsInsideScreen($DiscTypeX,$DiscTypeY))

Func _IsInsideScreen($x,$y,$screenX = 0,$screenY = 0)
    If $screenX = 0 Then $screenX = DllCall('user32.dll', 'int', 'GetSystemMetrics', 'int', 78)
    If $screenY = 0 Then $screenY = DllCall('user32.dll', 'int', 'GetSystemMetrics', 'int', 79)
    If $x > $screenX[0] Or $x < 0 Or $y > $screenY[0] Or $y < 0 Then Return 0
    Return 1
EndFunc

Perfect, yeah I just want to make sure it's a coordinate the mouse can actually get to so the macro doesn't go nuts lol

Thanks man
