TfrPictureView / Band OnBeforePrint

mrissmann

Hey Guys,

I have a (TfrBandView) Child band. I have a TfrPictureView component on that band. Blob type btBMP.

If there is no data stored in the Datafield for the TfrPictureView how do I not print the band? I am trying to use the scripting language and the OnBeforePrint of the child band?

Any help would be much appreciated.

Hi!

Use the FIELDISNULL internal function for testing the field for null value.

The function doesn't appear to work. It always evaluates to true (even though it is not)


begin
if (FieldIsNull([taDocumentPrintouts."Signature"])) and
(FieldIsNull([taDocumentPrintouts."Signature2"])) and
(FieldIsNull([taDocumentPrintouts."Signature3"]))
then
Child1.Visible := False
else
Child1.Visible := True
end

Some correction. Gord wrote in the Yahoo mail list not too much time ago.

if [(FIELDISNULL('CustomerData.Customers."Contact"'))]then

in 2.51 you'll find it in the expression builder under dabase functions.
note the ' ' around the module.table.fieldname
IIRC the expression builder won't add them

Try this.
