Symbian 3rd 带参数启动进程

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。
