MFC 建立一Dialog 应用程序，工程名字：Server 添加一Button控件command，并与之对应的函数OnCommand 在ServerDlg.h里添加自己的消息：#define WM_COMM...WM_USER+10 函数 OnCommand 添加代码： { CString str=”Client”; CWnd *pWnd=CWnd::FindWindow(NULL,str); if

onCommand() 在Service创建完成之后调用，该方法在客户端每次启动该Service时都会调用，用户可以在该方法中做一些调用统计、初始化类的操作。...public void onStart(Intent intent) { super.onStart(intent); } @Override public void onCommand...(Intent intent, boolean restart, int startId) { super.onCommand(intent, restart, startId);...如果Service尚未运行，则系统会先调用onStart()来初始化Service，再回调Service的onCommand()方法来启动Service。...如果Service正在运行，则系统会直接回调Service的onCommand()方法来启动Service。
