框架类OnCreate函数体中添加(HICON m_hIcon[3])
{
m_hIcon[0]=LoadIcon(AfxGetInstanceHandle(),MAKEINTRESOURCE(IDI_ICON1));
m_hIcon[1]=LoadIcon(theApp.m_hInstance,MAKEINTRESOURCE(IDI_ICON2));
m_hIcon[2]=LoadIcon(AfxGetApp()->m_hInstance,MAKEINTRESOURCE(IDI_ICON3));
SetClassLong(m_hWnd,GCL_HICON,(LONG)m_hIcon[0]);//设置图标为第一个,而不是默认的
SetTimer(1,1000,NULL); //定时器
}
然后添加框架类OnTimer函数
{
static int index=0;
SetClassLong(m_hWnd,GCL_HICON,(LONG)m_hIcon[index]);
index=++index%3;
}
