cdbOut (Function)

In french: cdbEnDehors

Used to determine if the record on which the position must be set is outside the 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).


	Accessible from the PC	Accessible from the simulator	Accessible from the Mobile Device (Pocket PC)
CDB database	Yes	Yes	Yes
Standard database	No	No	Yes

Example

// Read the first record found in Customer file
cdbReadFirst("MyDatabase", "Customer")
// Record outside the file?
WHILE cdbOut("MyDatabase", "") = False

// Process the record

...
END

// Standard "Contacts" database
// Read the first record
cdbReadFirst("", cdbContact)
// Record outside the file?
WHILE cdbOut("", cdbContact) = False
// Process the record
...
END

Syntax

<Result> = cdbOut(<Database> , <Data file>)

<Result>: Boolean

True if attempt to position on a record located outside the data file. In this case, the current record corresponds to the one before the move operation.
False if no problem occurred: the current record belongs to the data file.

<Database>: 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 (""), cdbOut will handle the last data file used by the last Mobile Device database management function (function starting with "cdb").
