Question

I have made a window with CreateWindowEx() function, now how do i get the width and height from that window i created? This sounds very basic thing to do, but i just couldnt find any answer ;_;

This is needed because the window height is created automatically depending on how the Windows wants to create it.

Language C or C++

Use GetWindowRect. Subtract the right from the left to get the width and the bottom from the top to get the height.

RECT rect; if(GetWindowRect(hwnd, &rect)) {   int width = rect.right - rect.left;   int height = rect.bottom - rect.top; } 

As a side note, if you’d like the client area instead of the entire window. You can use GetClientRect. For other information about the window you can use GetWindowInfo.
