In french: cdbNbEnr

Returns the number of records 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).

Example

// Number of records found in Customer file?
ResNbRecord = cdbNbRec("MyDatabase", "Customer")
Info("The number of records is: " + ResNbRecord)

// Standard "Contacts" database
// Number of records found in the Contacts file?
ResNbRecord = cdbNbRec("", cdbContact)
Info("The number of records is: " + ResNbRecord)

Syntax

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

<Result>: Integer

Number of records found,
-1 if an error occurred. To find out the error details, use ErrorInfo.

<Database>: Character string (with quotes)
