Tryng to launch an app via code on 3rd edition

[bytesm]

Hi all,

I've compiled a little program that simply try to launch another app on symbian 9.1 (both programs have capability: NONE)... The code i'm using is something like:

    TThreadId id;
    RApaLsSession ls;
    User::LeaveIfError(ls.Connect());
    CleanupClosePushL(ls);
    _LIT(KLitSwfFileToLaunch, "\\sys\\bin\\FLCustomVideoPlayer.exe");
    TFileName fileName(KLitSwfFileToLaunch);
    CompleteWithAppPath(fileName);
    User::LeaveIfError(ls.StartDocument(fileName,id));
    CleanupStack::PopAndDestroy(); //ls

but i'm always giving the error: "Unable to execute file for security reasons"

Do I have to give to "launcher" app a specific capability to run binary in sys folder?

thanks in advance
Leonardo

ps. Console apps need the capability too?

Just use RProcess to start the application.

You do not have read list or write access to \sys\bin

hi Paul,

thanks for your reply!
Using RProcess seems the right way:

        _LIT(KMyAppName, "FLCustomVideoPlayer.exe");
	RProcess EXE;
	int result = EXE.Create( KMyAppName, KNullDesC);	
	if (result!=KErrNone) Exit();
	EXE.Resume();
	EXE.Close();

Hi,

thanks to your help i'm able to launch my app from a console application... now i've the necessity of passing to the app some parameters. Tryng:

EXE.SetParameter(0, KParams);

crash my app, and if i try:

EXE.SetParameter(1, KParams);

nothing happens (process does not start at all).

Can you help me on this, please?

Sorry, I just do not know how to pass parameters with SetParam. However if your FLCustomVideoPlayer.exe is a GUI app, you can use

CApaCommandLine *cmd=CApaCommandLine::NewLC();
cmd->SetCommandL(EApaCommandRun);
cmd->SetExecutableNameL(_L("FLCustomVideoPlayer.exe"));
cmd->SetTailEndL(_L8("Some Parameter"));
RApaLsSession als;
User::LeaveIfError(als.Connect());
CleanupClosePushL(als);
User::LeaveIfError(als.StartApp(*cmd));
CleanupStack::PopAndDestroy(2);

to pass "Some Parameter" to it (you can also check what other fields CApaCommandLine has - e.g. Document, etc.), and it will get the CApaCommandLine in AppUi::ProcessCommandParametersL (you can use - overload - only the 1- and 3-parameters form, since the 2-params method is not virtual).
