添加和删除显示任务栏图标示例

void CProcessDlg::addTray()//添加显示任务栏图标
{
	NOTIFYICONDATA tnd;
	tnd.cbSize=sizeof(NOTIFYICONDATA);
	tnd.hWnd=this->m_hWnd;
	tnd.uID=IDI_ICON1;//任务栏显示的图标
	tnd.uFlags=NIF_MESSAGE|NIF_ICON|NIF_TIP;
	tnd.uCallbackMessage=WM_TRAY;// 
	tnd.hIcon=LoadIcon(AfxGetInstanceHandle(),MAKEINTRESOURCE(IDI_ICON1));
	strcpy(tnd.szTip,"屏蔽系统鼠标右健程序，双击图标弹出窗口");//图标提示为"测试程序"
	Shell_NotifyIcon(NIM_ADD,&tnd);//向任务栏添加图标
}

void CProcessDlg::delTray()//删除任务栏图标
{
	NOTIFYICONDATA tnd;
	tnd.cbSize=sizeof(NOTIFYICONDATA);
	tnd.hWnd=this->m_hWnd;
	tnd.uID=IDI_ICON1;
