How do you make a window topmost in win32?

A window can be made a topmost window either by setting the hWndInsertAfter parameter to HWND_TOPMOST and ensuring that the SWP_NOZORDER flag is not set, or by setting a window's position in the Z order so that it is above any existing topmost windows.

How do you bring a window to the foreground in C++?

SetForegroundWindow() is used to actually bring a window to the foreground. This can be a window of the calling application, or a window belonging to another application.

What is the difference between HWND and handle in Windows?

According to MSDN, HANDLE and HWND are defined as: HANDLE is a handle to an object. HWND is a handle to a window.
