What would be some reasons for the Document class's overloaded OpenFileL( TBool aDoOpen, const TDesC& /*aFilename*/, RFs& /*aFs*/ ) method not being called? I can't seem to retrieve any arguments passed into my application.

Calling app:
      TThreadId threadId;
      _LIT( KAppExtension, ".app" );
      iCmdLine = CApaCommandLine::NewLC();
      TFullName iExeFileName = _L("c:\\system\\apps\\basicapp\\basicapp");
      TFileName newname = iExeFileName;
      newname.Append( KAppExtension );

      _LIT( KDoc, "c:\\documents\\app.dat" );
      iCmdLine->SetDocumentNameL( KDoc );
      iCmdLine->SetLibraryNameL( newname );
      iCmdLine->SetCommandL( EApaCommandRun );
      iCmdLine->SetTailEndL( _L8( "String" ) );

      RApaLsSession ls;
      User::LeaveIfError( ls.Connect() );
      CleanupClosePushL( ls );
      User::LeaveIfError( ls.StartApp( *iCmdLine ) );

      CleanupStack::PopAndDestroy( 2 ); // iCmdLine, close ls

Called app has this code:
CFileStore* CQBasicAppDocument::OpenFileL( TBool aDoOpen, const TDesC& /*aFilename*/, RFs& /*aFs*/ )
   {
   if( aDoOpen )
      {
      // (aFilename is your doc name)
      TInt len = RProcess().CommandLineLength();
      iCmdlineBuffer = HBufC::NewLC( len );
      TPtr cmdline( iCmdlineBuffer->Des() );
      RProcess().CommandLine( cmdline );
      }
   return(NULL);
   }
however it is never called.
And also this:

GLDEF_C TInt E32Dll(TDllReason)
   {
   TInt len = RProcess().CommandLineLength();
   if( len > 0 )
      {
      TBuf<256> cmdLineBuf;
      RProcess().CommandLine( cmdLineBuf );
      }
   TBuf<256> cmdLineBuf;
   RProcess().CommandLine( cmdLineBuf );
   return KErrNone;
   }
len is always 0 and cmdLineBuf never contains anything..

If someone has some ideas please let me know.

Hi,

Your App Ui owns the document so you can always access it via the Document() method after it has been created.

How can I pass the params recived in this method to MyAppUi class??

Quote from: eric

Override the OpenFileL() method in your AppDocument.cpp file.
The methods will be automatically called by the framework with your doc (iDoc) in the aFilename parameter.

Code:

CFileStore* CYourAppDocument::OpenFileL(TBool aDoOpen,const TDesC& aFilename,RFs& aFs)
{
if(aDoOpen)
{
// Do what you want
// (aFilename is your doc name)
...
}
return(NULL);
}

Hi,
Overriding this should work:

CEikAppUi::ProcessCommandParametersL(TApaCommand aCommand,TFileName& aDocumentName,const TDesC8& aTail)

There is more info in the Symbian documentation.

Hi pawel, i had read this document, but what I need is how to read the params in the called app.
I must do anything more??
My app must support document??
The called app reads the param in the MyAppUi::ConstructL method.
Someone told me that this issue is only in the emulator.
Thx.

Hi,

The code you have pasted should work just fine - looks like the error could be somewhere else. If you have not seen this link yet, have a look here:
