NbThumbnail (Property)

In french: NbVignette

Available only with these kinds of connection

..NbThumbnail is used to find out the number of thumbnails generated for an item. This item was defined in the data model editor or by programming.

Remark: The HFSQL thumbnails of an item are automatically generated:

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

Remark: From version 19, HFSQL is the new name of HyperFileSQL.

Example

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