can not open the default contact database

[znrabbit]

I use the commonframework.h as my head file, and fill my code into the doExampleL() .It crashes when it try to open the defualt database,and the emulator close down immediately.but before that ,everything is fine.The name of the database has print out.what is the problem?the database does not exist? what shall I do?

#include "commonframework.h"
#include <cntdef.h>
#include <cntdb.h>
#include <cntitem.h>
#include <cntfldst.h>


// do the example
LOCAL_C void doExampleL()
{
static CContactDatabase *cdb;
static CContactIdArray const *contacts;
CContactItem *item;
int i, n;


_LIT(KTxtcontact,"contactlist:\n");
TBuf<256> info(KTxtcontact);
console->Printf(KTxtcontact);
// Read name of the default database
TBuf<60> contactDBFile; //KOrgContactFile );
CContactDatabase::GetDefaultNameL( contactDBFile );
contactDBFile.LowerCase();
console->Printf(contactDBFile);

//Open default database
TRAPD(err, cdb= CContactDatabase::OpenL(contactDBFile));
CleanupStack::PushL(cdb);
//Check if database exists
if ( err == KErrNotFound )
{
_LIT(Error,"not exist");
console->Printf(Error);
}
else
{
_LIT(KTxtOK3,"ok3");
console->Printf(KTxtOK3);

}
CleanupStack::PopAndDestroy(cdb);
}

After several attemps, I finally find out what is wrong.
1. exe is too simple a framework for database operation. I use the app framework instead.
2. when I set up the sdk, I didn't choose the default path. So ,the dll may not be able to locate the database.

After I fix these to mistakes, it works.

Hi,
I'm Also facing same problem
my code is
TRAP( _resError, (contactsDb = CContactDatabase::OpenL()) );
User::LeaveIfError(_resError);

TRAP( _resError, CleanupStack::PushL(contactsDb));
User::LeaveIfError(_resError);
and it hangs on 3rd line
How can I solve the problem?
Above code is in a static function which will be called by a view
