}

TInt CMapContact::FindContactsFromDbL(TDesC& aMobileNumber)

so error is comming functions mismatch.so plz me how i can TBuf type to functions which is returning int type

Hi use like this...

TInt CMapContact::FindContactsFromDbL([COLOR="Red"]TDes&[/COLOR] aMobileNumber)

or if not solve, can shre what are u doing in this function with aMobileNumber.

Input descriptor parameters should be passed as const TDesC&, output parameters should be passed as TDes&.

Please don't name local variables beginning with an i.
