Overview

Launching Calendar application in day view

Description

The following code example demonstrates how to launch the Calendar application in day view. The date will be specified with the aDate parameter. If aDate is NULL, Calendar will open the view in current date (today).

Capability requirements: SwEvent

Headers:

 #include <w32std.h>    // RWsSession (ws32.lib)
 #include <apgtask.h>   // TApaTaskList,TApaTask (apgrfx.lib)
 #include <apgcli.h>    // RApaLsSession (apgrfx.lib)
 #include <apaid.h>     // TApaAppInfo (apparc.lib)
 #include <apacmdln.h>  // CApaCommandLine (apparc.lib)

Constants:

   // UID of the Calendar Application:
   const TUid KCalendarAppUID = { 0x10005901 };
   
   // Format strings for constructing parameters passed to Calendar
   _LIT( KCalCmdTODAY, "TODAY" ); 
   _LIT( KCalCmdDATE, "DATE " );
   _LIT( KCmdTimeFormat, "%F%Y %M %D %H %T %S %C" );
   #define KCalTimeParamMaxLen 36

Implementation:

   void LaunchCalendarL( const TTime* aDate )
     {  
     TBuf<KCalTimeParamMaxLen> paramsBuf( KCalCmdTODAY );
         
     // if a specific date is given, construct command line parameters
     // using "DATE YYYY MM DD HH MM SS MMMMMM" format
     
     if( aDate )         
       {       
       aDate->FormatL( paramsBuf, KCmdTimeFormat() );
       paramsBuf.Insert( 0, KCalCmdDATE );
       }
         
     // package the parameters, so it can be passed
     // as an 8-bit descriptor
     TPckg< TBuf16<KCalTimeParamMaxLen> > paramsPkg( paramsBuf );
         
     // Check if the Calendar is already running
     TApaTaskList taskList( iCoeEnv->WsSession() );
     TApaTask task = taskList.FindApp( KCalendarAppUID );
   
     if( task.Exists() )  // Calendar already open
       {
       TInt ret = task.SendMessage( KNullUid, paramsPkg ); // requires SwEvent       
       task.BringToForeground();
       }
     else  // Launch Calendar in day view
       {
       TApaAppInfo appInfo;
       RApaLsSession lsSession;
       User::LeaveIfError(lsSession.Connect());
       CleanupClosePushL( lsSession );
                   
       if( lsSession.GetAppInfo( appInfo, KCalendarAppUID ) == KErrNone )
         {
         // Construct a CApaCommandLine instance and start Calendar
         CApaCommandLine* cmdLine = CApaCommandLine::NewLC();
         cmdLine->SetExecutableNameL( appInfo.iFullName );
         cmdLine->SetCommandL( EApaCommandRun );
         cmdLine->SetTailEndL( paramsPkg );
         lsSession.StartApp( *cmdLine );
         CleanupStack::PopAndDestroy( cmdLine );
         }          
       CleanupStack::PopAndDestroy();  // close lsSession
       }
     }
