WM_GETMINMAXINFO problem when window is maximized
I want to reduce (by 1 only pixel) the height of a window when it is show maximized.
In my window procedure I have the following code in C++:
case WM_GETMINMAXINFO:
LPMINMAXINFO minmaxinfopunt = (LPMINMAXINFO) lParam;
minmaxinfopunt>ptMaxSize.y = 1;
return 0;
Now a strange thing happen:
 with values from 1 to 16 (that is, from "minmaxinfopunt>ptMaxSize.y = 1;" to "minmaxinfopunt>ptMaxSize.y = 16;") I always get the height previously memorized in ptMaxSize.y, that is, the mazimized (by the system) height of the window.
 with values equal or greater than 17 I get the height of the window reduced as aspected.
I can I solve this problem?
Thanks.

What is the value of GetSystemMetrics(SM_CYMIN)? What about the other SM_CY?? values on the system?

GetSystemMetrics( SM_CYMIN ) is 38 on my system.
But I don't understand what I have to do.

Re: WM_GETMINMAXINFO problem when window is maximized
I was just wondering if it was the same problem I had a few years ago when trying to create a very narrow window. Amongst other things, system metrics state the smallest x and y size of a window. As the code works for you if the size is 17 or above but not if it is less then 17 I thought it might have to do with these metrics (there are loads of these if you look up the documentation for GetSystemMetrics). I was hoping for a value of 16!
