NbThumbnail (Property)

In french: NbVignette

Available only with these kinds of connection

The NbThumbnail property is used to get the number of thumbnails generated for an item. This item was defined in the data model editor or programmatically.

Remark: HFSQL thumbnails for a heading are generated automatically when:

when writing the corresponding record (HAdd or HWrite),
when modifying the value of the item (HModify),
of the automatic modification of data files.

Example

// Get the number of generated thumbnails 
// and the number of expected thumbnails
// for the Customer.Photo item
NumberThumbnail is int
ExpectedNumberThumbnail is int
NumberThumbnail = Customer.Photo.NbThumbnail
ExpectedNumberThumbnail = Customer.Photo.NbDescribedThumbnail
// Same number?
IF NumberThumbnail = ExpectedNumberThumbnail THEN
	Info("All the thumbnails have been generated")
ELSE
	FOR Number = 1 TO ExpectedNumberThumbnail
		ErrorString += "Thumbnail " + Number + Customer.Photo.InfoThumbnailGeneration[n] + CR
	END
	Error("Generation error", ErrorString)
END
