Hi , I'm trying to display all the messages in a draft folder Using the following method in the application engine:
#include <badesca.h>
#include <e32des8.h>
#include <e32des16.h>
#include "MyEmailEngine.h"
///----->Getting The Draft Folder Of Sms Messages
void CMyEmailEngine :: GetAllMessagesFromSystemDraftFolderL(CDesCArray& tempMess)
{ _LIT(KDraftString,"\t%S"😉;
TBuf<2000> aDraftString;
TBuf<1000> tempBuf;//iMsvSession
////CMsvEntry* entry = iSession->GetEntryL(KMsvDraftEntryId);
CMsvEntry* entry = iMsvSession->GetEntryL(KMsvDraftEntryId);
CleanupStack::PushL(entry);
CMsvEntrySelection* entries = entry->ChildrenL();
CleanupStack::PopAndDestroy(entry) ;
//entry = NULL ;
TInt nCount = entries->Count();
for(TInt index = 0; index < nCount; index++)
{
TMsvId entryID = entries->At(index);
//entry = iSession->GetEntryL(entryID);
entry = iMsvSession->GetEntryL(entryID);
CleanupStack::PushL(entry);
TMsvEntry msvEntry = entry->Entry();
TPtrC nn = msvEntry.iDescription;
tempBuf.Zero();
tempBuf.Format(_L("%S"😉,&nn);
tempLength = tempBuf.Length(); //always 60 if message is more than 60 characters
aDraftString.Format(KDraftString(),&tempBuf);
tempMess.AppendL(aDraftString);
CleanupStack::PopAndDestroy(entry); // entry
}
}
///----->End
When I compile the project it gives the following Link error:

InternetEmail - 2 error(s), 4 warning(s)
Although that I included all the libraries + Headers needed for the project (method) but still the error continued, when I comment on the method every thing on the project goes successfully which assures that the problem coming from the method(GetAllMessagesFromSystemDraftFolderL).

I'm getting Upset Why this Error Cntinued?
