Deletes the current record or the specified record from the data file. The indexes (corresponding to the record keys) are deleted from the index file.
Caution: From Windows Mobile 5, the access to a standard database (tasks, contacts, appointments, ...) can no longer be performed from a Windows application (and therefore from a standard WINDEV application).

Example
// Delete the current record from Customer file
ResDelete = cdbDelete("MyDatabase", "Customer")
// Has a problem occurred?
IF ResDelete = False THEN Error(ErrorInfo())
// Standard "Contacts" database
// Delete the current record from the Contacts file
ResDelete = cdbDelete("", cdbContact)
// Has a problem occurred?
IF ResDelete = False THEN Error(ErrorInfo())
Syntax
<Result> = cdbDelete(<Database Name> , <Data File> [, <Record Number>])
<Result>: Boolean
  • True if the function was successful,
  • False otherwise. 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 (""), cdbDelete handles the last data file used by the last function for managing the databases found on Mobile Device (starting with cdb).
<Record Number>: Optional integer
Number of the record to delete. This number is returned by cdbRecNum. If this parameter is not specified, cdbDelete handles the current record.
Caution: The record numbers are not consecutive numbers.
