Active Window Height and Width in Pixels

---

Question:

Is there a way to determine the height and width of the active window in pixels?

Answer:

Yes. You can get pretty close by doing a WinPlaceGet, and then picking apart the numbers (ItemExtract) then "converting the numbers to absolute coordinates with from fractions. From WinMetrics you know the pixel size of the entire screen. And the numbers returned from WinPlaceGet assume it is a 1000x1000 screen so you have to convert it. Alternatively some DllCall or other like GetWindowRect might do it. Pick the numbers apart with ItemExtract, using a comma as a delimiter.

a = ItemExtract( 1, rect, "," )
