Example
// Number of records found in Customer file?
ResNbRecord = cdbNbRec("MyDatabase", "Customer")
Info("The number of records is: " + ResNbRecord)
// Standard "Contacts" database
// Number of records found in the Contacts file?
ResNbRecord = cdbNbRec("", cdbContact)
Info("The number of records is: " + ResNbRecord)
Syntax
<Result> = cdbNbRec(<Database Name> , <Data File>)
<Result>: Integer
  • Number of records found,
  • -1 if an error occurred. To find out the error details, use ErrorInfo.
<Database Name>: Character string (with quotes)
  • Name of database that was opened by cdbOpen,
  • Empty string ("") to handle one of the standard databases found on Mobile Device (tasks, contacts, ...).
<Data File>: Character string (with quotes) or constant
Data file to use. This parameter corresponds to:
  • the name of data file to use.
  • the constant corresponding to one of the standard databases:
    cdbContact"Contacts" database
    cdbTask"Tasks" database
    cdbAppointment"Appointments" database
If this parameter corresponds to an empty string (""), cdbNbRec handles the last data file used by the last function for managing the databases found on Mobile Device (starting with cdb).
