1.定义消息宏

#define WM_TRAYICON_MSG (WM_USER+100)

2.任务栏托盘函数的封装

BOOL CWarEKeyDlg::TrayMyIcon(BOOL bAdd) { BOOL bRet = FALSE; NOTIFYICONDATA tnd; tnd.cbSize = sizeof(NOTIFYICONDATA); tnd.hWnd = m_hWnd; tnd.uID = IDR_MAINFRAME; if ( bAdd == TRUE ) { tnd.uFlags = NIF_MESSAGE | NIF_ICON | NIF_TIP; tnd.uCallbackMessage = WM_TRAYICON_MSG;//消息响应函数 tnd.hIcon = LoadIcon(AfxGetInstanceHandle(), MAKEINTRESOURCE(IDR_MAINFRAME)); _tcscpy_s(tnd.szTip, sizeof(tnd.szTip), _T("WarEkey")); bRet = Shell_NotifyIcon(NIM_ADD, &tnd); }else{ ShowWindow(SW_SHOWNA); SetForegroundWindow(); bRet = Shell_NotifyIcon(NIM_DELETE, &tnd); } return bRet; }

3.消息响应函数的添加：

ON_MESSAGE(WM_TRAYICON_MSG, OnTrayCallBackMsg) LRESULT CWarEKeyDlg::OnTrayCallBackMsg(WPARAM wparam, LPARAM lparam) { switch(lparam) { case WM_RBUTTONUP: { CMenu mMenu, *pMenu = NULL; CPoint pt; mMenu.LoadMenu(IDR_MENU); pMenu = mMenu.GetSubMenu(0); GetCursorPos(&pt); SetForegroundWindow(); pMenu->TrackPopupMenu(TPM_LEFTALIGN | TPM_RIGHTBUTTON, pt.x, pt.y, this); break; } case WM_LBUTTONDBLCLK: ShowWindow(SW_RESTORE); SetForegroundWindow(); break; default:break; } return NULL; }

4.初始化时一般都让其显示任务栏托盘，直到程序结束才将托盘去掉。重载WM_SYSCOMMAND

if (nID==SC_MINIMIZE) { ShowWindow(SW_HIDE); } if (nID==SC_CLOSE) { TrayMyIcon(FALSE); OnClose(); }
