symbian 下面调用电话拨号的方法

开发电话本应用的时候，时常会需要直接拨打对方的电话号码。 那么，如何在symbian s60平台上通过代码让自己的手机拨号呢？ 下面的代码可能会帮助你的： 加入头文件： #include <etel.h>            // for dial operatons 在mmp文件中需要加入： LIBRARY         etel.lib        // for dial operations TBool CMcAppUi::dialTel(TDesC & telNum) {         _LIT(KPHONE_DRV, "phonetsy.tsy") ;         //Create a connection to the tel server         RTelServer server;         CleanupClosePushL(server);         User::LeaveIfError(server.Connect());                 //Load in the phone device driver         User::LeaveIfError(server.LoadPhoneModule(KPHONE_DRV));                 //Find the number of phones available from the tel server         TInt numberPhones;         User::LeaveIfError(server.EnumeratePhones(numberPhones));                 //Check there are available phones         if (numberPhones < 1)        {                 User::Leave(KErrNotFound);         }                 //Get info about the first available phone         RTelServer::TPhoneInfo info;         User::LeaveIfError(server.GetPhoneInfo(0, info));                 //Use this info to open a connection to the phone, the phone is identified by its name         RPhone phone;         CleanupClosePushL(phone);         User::LeaveIfError(phone.Open(server, info.iName));                 //Get info about the first line from the phone         RPhone::TLineInfo lineInfo;         User::LeaveIfError(phone.GetLineInfo(0, lineInfo));                 //Use this to open a line         RLine line;         CleanupClosePushL(line);         User::LeaveIfError(line.Open(phone, lineInfo.iName));                 //Open a new call on this line         TBuf <100> newCallName;         RCall call;         CleanupClosePushL(call);         User::LeaveIfError(call.OpenNewCall(line, newCallName));                 //newCallName will now contain the name of the call         User::LeaveIfError(call.Dial(telNum));                 //Close the phone, line and call connections and remove them from the cleanup stack         //NOTE: This does not hang up the call         CleanupStack::PopAndDestroy(3);//phone, line, call                 //Unload the phone device driver         User::LeaveIfError(server.UnloadPhoneModule(KPHONE_DRV));                 //Close the connection to the tel server and remove it from the cleanup stack         CleanupStack::PopAndDestroy(&server);         return ETrue ; } 这段代码很好用的，在多款s60真机上测试过
