Alright I have a couple of code snippets I want to know what exactly they do I mean what everything means not just what it is doing.
bActive = !((BOOL)HIWORD(wParam));
Alright I know it is typecasting HIWORD into a boolean variable but what is HIWORD(wParam) if I remember isn't wParam split into two 16 bit integers. So would HIWORD be taking the first of the two integers?
Thanks anyone who helps
wparam and lparam are additional info passed in a Windows program with a message.
this is a size msg recieved in the callback and then the x,y coods are extracted so the window can be redrawn at the correct size.Code:case WM_SIZE: cxSize=(int)(LOWORD(lParam)); cySize=(int)(HIWORD(lParam));
In yours it looks like a flag is checked to the see if it is not equal to current.
