- Accessing a database found on the Mobile Device (Pocket PC)
cdbRecNum (Function) In french: cdbNumEnr Returns the number of the current record found in a data 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 |
// Number of the current record in Customer file?
ResCurrentNum = cdbRecNum("MyDatabase", "Customer")
Info("The number of the current record is: " + ResCurrentNum)
// Standard "Contacts" database
// Number of the current record in the Contacts file?
ResCurrentNum = cdbRecNum("", cdbContact)
Info("The number of the current record is: " + ResCurrentNum)
Syntax
<Result> = cdbRecNum(<Database> , <Data file>)
<Result>: Integer Corresponds to:- the number of the current record in the data file.
- the hInvalidRecNum constant if there is no current record (position outside the data file).
If an error occurs, you can get the details of the error with ErrorInfo. <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 (""), cdbRecNum will handle the last data file used by the last Mobile Device database management function (function starting with "cdb").
