Windows class

everything in Windows is a window, ie: buttons, scrollbars, text boxes, etc. (they are all derived from a common base class).

To create your own window, you must create a window class. To do this define:

typedef struct _WNDCLASS

{ UINT style; // style flags

WNDPROC lpnWndProc; // ptr to event handler

int cbClsExtra; // extra bytes

int cbWndExtra; // extra bytes

HANDLE hinstance; // handle of instance

HICON hIcon; // handle of icon

HCURSOR hCursor; // handle of cursor

HBRUSH hbrBackground; // handle of background brush

LPCTSTR lpszMenuName; // name of menu

LPCTSTR lpszClassName; // name of class

} WNDCLASS;

WNDCLASS wndclass; // an instance of a window class
