Visual C++ and MFC Programming 2nd Edition

Chapter 12: Dialog-Based Windows Visual C++ and MFC Fundamentals

The LoadIcon() member function returns an HICON object that you can assign to the

hIcon member variable of your WNDCLASS object. Here is an example:

CMainFrame::CMainFrame()

{

WNDCLASS WndCls;

WndCls.style = CS_VREDRAW | CS_HREDRAW;

WndCls.lpfnWndProc = AfxWndProc;

WndCls.cbClsExtra = 0;

WndCls.cbWndExtra = 0;

WndCls.hInstance = AfxGetInstanceHandle();

WndCls.hIcon = LoadIcon(NULL, IDI_WARNING);

}

You can also declare an HICON handle and initialize it with

CWinApp::LoadStandardIcon() method as follows:

AfxGetApp()->LoadStandardIcon(StdIcon);

A cursor is used to locate the position of the mouse pointer on a document or the screen.

To use a cursor, call the Win32 LoadCursor() function. Its syntax is:

HCURSOR LoadCursor(HINSTANCE hInstance, LPCTSTR lpCursorName);

The hInstance argument is a handle to the file in which the cursor was created. This file is

usually stored in a library (DLL) of an executable program. If the cursor was created as

part of your application, you can use the hInstance of your application. If your are using

one of the below cursors, set this argument to NULL.

When Microsoft Windows installs, it also installs various standard cursors you can use in

your program. Each one of these cursors is recognized by an ID which is simply a

constant integers. The available cursors are:

application is not stable
