Get window width... by deAd on 07-25-2006 at 07:00 PM
How would I go about getting the width in pixels of a window? I've tried using GetWindowRect but I can't get it right...
RE: Get window width... by Eljay on 07-25-2006 at 07:17 PM
code:
var RECT = Interop.Allocate(16);
Interop.Call('User32', 'GetWindowRect', <window handle here>, RECT);
var left = RECT.ReadDWORD(0);
var right = RECT.ReadDWORD(8);
var width = right - left;

Oh...I didn't know which one was the right I guess 
Which ones are the Top/Bottom?

quote:
typedef struct _RECT {
LONG left;
LONG top;
LONG right;
LONG bottom;
} RECT, *PRECT;
source: MSDN
so .ReadDWORD(4) = top
and ReadDWORD(12) = bottom

I would've guessed that it went 1,2,3,4 (or 0,1,2,3)

Too lazy to type it all out so here is what Choli posted in the beta forum.

Oh...I've used datablocs before but I've never seen this. Thanks
