GetWindowRect Function

HI,

below is a piece of code.

HWND hVWnd;
RECT rRect;

GetWindowRect(hVWnd,&rRect);
diff_val = rRect.bottom-rRect.top;

If on starting a application if my window is minimized then value of rRect.top and
rRect.bottom is -32000.

Is it a garbage value or any valid error code

Once my window get normal size it gives me a valid wondow cordinates. (such as 405, 395 ..)

my question is,
when a window is minimize then GetwindowRect's top propery is always -32000.

or it could be any other garbage value.

Waiting for your reply

Many thanks

That means in all cases if window is minimized it will always returns -32000
or its value may change if we change OS or upgrade with new service pack.

I would post this on any of the windows forums as I won't be able to give 100% accurate answers.

If it were for me, I woudn't depend on the exact number.

The value -32000 is NOT a garbage one. I believe coordinates could not be less than -32000 or greater than +32000.
It could be a windows criteria where minimized windows are put into coordinates (-32000,-32000).

I did a quick search and here is a blog that explained such issue:
