Purpose

The Calendar Exporter API provides functions to export agenda entries to vCalendar data.

Header files

 #include <calsession.h>
#include <calprogresscallback.h>
#include <calentryview.h>
#include <calenexporter.h>
#include <caliterator.h>
#include <f32file.h>
#include <S32FILE.H>
#include <agnexportobserver.h>

Libraries used

 efsrv.lib calinterimapi.lib calenimp.lib estor.lib

Code example

The CCalSession is the interface to the Calendar file. The instantiation of CCalSession will result in a connection to the Calendar Server.

 void CCalendarEventsEngine::ConstructL()
{
iCalSession = CCalSession::NewL();
//Open the default calendar file
iCalSession->OpenL(iCalSession->DefaultFileNameL());
iWaiter =new (ELeave) CActiveSchedulerWait;
// calender exporter
iExporter=CCalenExporter::NewL(*iCalSession);
}

Virtual functions

 // Called during calendar entry view creation
void CCalendarEventsEngine::Progress(TInt aProgress)
{
}
 
// Called on completion of calendar entry view creation
void CCalendarEventsEngine::Completed(TInt aError)
{
iWaiter->AsyncStop();
}
 
// Returns whether or not progress notification is required
TBool CCalendarEventsEngine::NotifyProgress()
{
// Progress notification is required
return ETrue;
}

The following code exports calender entries to a file:

 void CCalendarEventsEngine::ExportEntriesL()
{
if(iWaiter->IsStarted())
{
iWaiter->AsyncStop();
}
// view class for accessing calendar entries
iCalEntryView = CCalEntryView::NewL(*iCalSession,*this);
iWaiter->Start();
// An iterator for iterating though all the entries in the calendar store
CCalIter* calIter = CCalIter::NewL(*iCalSession);
TBuf8<150> iterUID;
// An array of calender entries
RPointerArray<CCalEntry> calEntryArray;
iterUID = calIter->FirstL();
// calender entries file
_LIT(KFile,"C:\\CalEntriesFile.txt");
User::LeaveIfError(iFs.Connect());
TInt err = iRWriteStream.Open(iFs,KFile,EFileWrite);
if(err !=KErrNone)
{
User::LeaveIfError(iRWriteStream.Create(iFs, KFile, EFileWrite));
}
while (iterUID != KNullDesC8)
{
// get entries associated with this UID
iCalEntryView->FetchL(iterUID, calEntryArray);
for (TInt k=0; k<calEntryArray.Count();k++)
{
// get information from this entry
CCalEntry* calEntry = calEntryArray[k];
// export calender entry
iExporter->ExportVCalL(*calEntry,iRWriteStream);
}
iterUID = calIter->NextL();
};
calEntryArray.ResetAndDestroy();
delete calIter;
delete iCalEntryView;
iRWriteStream.Close();
iFs.Close();
}

Sample application

The following sample application is tested in the S60 3rd Edition, FP2 emulator. File:CalenderImpportExport.zip
