Stored procedures
Modifies the specified record or the record found in memory in the data file. The indexes corresponding to all the keys used in the file are automatically updated.
To modify the record found in memory, use cdbWriteCol.
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
// Modify the current record in Customer file
cdbWriteCol("MyDatabase", "Customer", "LastName", "Smith")
cdbWriteCol("MyDatabase", "Customer", "FirstName", "Paul")
cdbWriteCol("MyDatabase", "Customer", "City", "Avignon")
ResModification = cdbModify("MyDatabase", "Customer")
// Has a problem occurred?
IF ResModification = False THEN Error(ErrorInfo())
// Standard "Contacts" database
// Modify a record
cdbContact.Name = "Smith"
cdbContact.FirstName = "Paul"
cdbContact.HomeCity = "Avignon"
ResModification = cdbModify("", cdbContact)
// Has a problem occurred?
IF ResModification = False THEN Error(ErrorInfo())
Syntax
<Result> = cdbModify(<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 (""), cdbModify handles the last file used by the last function for managing the Mobile Device databases (starting with the letters cdb).
<Record Number>: Optional integer
Number of the record to modify. This number is returned by cdbRecNum. If this parameter is not specified, cdbModify handles the current record.
Caution: The record numbers are not consecutive numbers.
