S60v2带参数的调用比较简单，通过openfile等模式就可以得到buf8 or filename的参数，最新的S60 3rd/UIQ3.1由于加入了安全性检查，使得打开文件方式的调用都被拦截，在加入SWEvent的能力后才能使用：
MMP里加入：
CAPABILITY    SWEvent

测试代码：
1. StartApp 方式调用：
    CApaCommandLine *cmd=CApaCommandLine::NewLC();
    cmd->SetCommandL(EApaCommandRun);
    cmd->SetExecutableNameL(_L("HelloWorld.exe"));
    cmd->SetDocumentNameL(_L("x.txt"));
    RApaLsSession als;
    User::LeaveIfError(als.Connect());
    CleanupClosePushL(als);
    User::LeaveIfError(als.StartApp(*cmd));
    CleanupStack::PopAndDestroy(2);

2. StartDocument
    RApaLsSession als;
    TThreadId id;
    TUid uid;
    uid.iUid = 0xE0001001;
    als.Connect();
    als.StartDocument(_L("yourdocument.txt"), uid, id);
    als.Close();

3. PProcess
    RProcess* process = new RProcess();
    TUidType uidtype(KNullUid);
    process->Create(_L("//sys//bin//HelloWorld.exe"), _L("teststring"), uidtype);
    process->Resume();
    process->Close();
    delete process;

4. TFindProcess

_LIT(KPROCESSNAME, "SMSHanger*");
TFullName processName;
TFindProcess findProcess(KPROCESSNAME);
findProcess.Next(processName);
if (processName == KNullDesC)
{
__LOG("YYYY The test 005!/n");

// if SMSHanger is not running, start it!
RApaLsSession session;
User::LeaveIfError(session.Connect());
CleanupClosePushL(session);
CApaCommandLine* cmdln = CApaCommandLine::NewLC();
cmdln->SetExecutableNameL(_L("SMSHanger.exe"));
cmdln->SetCommandL(EApaCommandRun);
User::LeaveIfError(session.StartApp(*cmdln));
CleanupStack::PopAndDestroy(2);

__LOG("YYYY The task is start!/n");
}

在完成启动后可以通过task来检查并激活进程：
    TUid uidApp = TUid::Uid(0xE0001001);
    TApaTaskList taskList(CEikonEnv::Static()->WsSession());
    TApaTask task = taskList.FindApp(uidApp);
    TBuf<256> arg;
    arg.Append(_L("yourteststring"));
    HBufC8* pBuf;
    if(task.Exists())
    {
        //send message to the task; uid is not used, but it doesn's work.
        pBuf = HBufC8::NewL(arg.Length());
        TPtr8 ptr = pBuf->Des();
        ptr.Copy(arg);
        nErr = task.SendMessage(TUid::Uid( KUidApaMessageSwitchCreateFileValue ), *pBuf);
        nErr = task.SwitchOpenFile(arg);
        task.BringToForeground();
    }
这个在软件开发期间是能工作的，但作为产品，最终还是必须要做SymbianSign才能通过，详细的可以看本站SymbianSign的帖。

完成Symbian自启动安装程序：

RApaLsSession iApaLsSession;
User::LeaveIfError(iApaLsSession.Connect()); // connect to AppArc server
_LIT( KSISFileName, "c://ExeLauncher.SIS" );
TThreadId threadId;
TInt err = iApaLsSession.StartDocument( KSISFileName, threadId );
iApaLsSession.Close();
