Launching exe on S60 3rd edition

[puh_sk8@hotmail.com]

Hi

Hope someone can help me with this...

I have 2 apps, the first is a simple HelloWorld GUI app. this works fine and runs off the icon no problem.

My second app is another GUI app but with different name and UID. When the user presses the icon for the second app i want it to open up, start the first app and then close.

here is the code i am using...

  RProcess server;
  server.Create(KServerName, KNullDesC);

  CApaCommandLine* commandLine = CApaCommandLine::NewL();
  commandLine->SetExecutableNameL(KExecutableName);
  commandLine->SetProcessEnvironmentL(server);

  RApaLsSession ApaSession;
  ApaSession.Connect();
  ApaSession.StartApp(*commandLine);
  ApaSession.Close();

  delete commandLine;

which i got from Symbian Example

I get no errors in the compiling and i can install on the device, but when i click the icon the screen flashes as if the app is starting but then returns to the main menu without starting the other app.

the executable i'm trying to launch is c:\sys\bin\HelloWorld.exe and it has a UID from the unprotected range (0xA000161C)

What values should KExecutableName, KServerName and KNullDesC be set to?
Should these be filenames/UID/something else?

I'm using Carbide.C++ Express for development.

I'm totally new to c++ so i'm really greatful for all the help i can get.

KExecutableName should be the name of the app you are trying to launch. Namely, c:\sys\bin\HelloWorld.exe.

KNullDesC passes a command to the initial thread of the process you are trying to create. You can leave this blank unless you know you need something here.

Try running your app with TaskSpy running the background. TaskSpy will report Panics in case you're doing something wrong.

At the moment i have KExecutableName set like...

_LIT(KExecutableName, "c:\\sys\\bin\\HelloWorld.exe");

I have also tried...
c:\\sys\\bin\\HelloWorld
c:\sys\bin\HelloWorld
c:\sys\bin\HelloWorld.exe
c:\\sys\\bin\\0xA000161C
c:\sys\bin\0xA000161C
HelloWorld.exe
HelloWorld
and
0xA000161C

none of these start my other app.

Which is the correct path/format for the executable name?

Does the KServerName have to be a specific value? what should i set this to?

Try using this code:

CApaCommandLine* comndLine = CApaCommandLine::NewLC();
comndLine ->SetExecutableNameL( aExe );// aExe is exe name in buffer
comndLine ->SetCommandL( EApaCommandRun );
RApaLsSession apaSession;
apaSession.Connect();
apaSession.StartApp( *comndLine );
apaSession.Close();
CleanupStack::PopAndDestroy( comndLine );

Thanks Tina, that worked great...

Where the SetExecutableNameL appears, is it possible to set a document name to open in that app?

eg. if i was calling a picture viewer, could i tell it to open with a specified jpg?

something like...

_LIT(KJpegName, "C:\\data\\others\\image.jpg");
comndLine->SetDocumentL(KJpegName);

I think i have seen this somewhere before but i don't know where?
