Stored procedures
Positions on the first file record and reads this record.
In most cases, cdbReadFirst is used to position in the data file in order to perform a read loop with cdbReadNext.
After the call to cdbReadFirst, if the data file is empty:
  • no read operation is performed,
  • cdbOut returns True.
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
// Read the first record found in Customer file
cdbReadFirst("MyDatabase", "Customer")
// Record outside the file?
WHILE cdbOut("MyDatabase", "") = False
        // Process the record
        cdbReadNext("MyDatabase", "")
        ...
END
// Standard "Contacts" database
// Read the first record
cdbReadFirst("", cdbContact)
// Record outside the file?
WHILE cdbOut("", "") = False
        // Process the record
        cdbReadNext("", "")
        ...
END
Syntax
<Result> = cdbReadFirst(<Database Name> , <Data File>)
<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 (""), cdbReadFirst handles the last data file used by the last function for managing the Mobile Device databases (starting with the letters cdb).
