- Accessing a database found on the Mobile Device (Pocket PC)
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 |
// 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 of the 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 handles the last data file used by the last function for managing the Mobile Device databases (starting with the letters cdb). Remarks Accessing a database found on the Mobile Device (Pocket PC) The table below presents the actions that must be performed to access a database found on Mobile Device: | | | | Database | Standard database (tasks, contacts,
appointments, ...) | | Standard WINDEV application | - Establish a connection between the current computer and the Mobile Device (ceConnect).
- Open the database to use (cdbOpen).
| Establish a connection between the current computer and the Mobile Device (ceConnect). | | WINDEV Mobile application | Open the database to use (cdbOpen). | No specific action is required. |
