ppDetailBand eAccessViolation

rbuser

Hi,

After succesfully compiling several times my project using RB 6.03 Std,
now I am getting the error : EAccessViolation em ppBands, line
2067, procedure TppDetailBand.DefineProperties(Filer: TFiler), see
following the 2067 line :

{if no ancestor, then write it, if it exists}
if (Filer.Ancestor = nil) or (TppDetailBand
(Filer.Ancestor).DataPipeline = nil) then
lbWrite := (FDataPipeline <> nil)

Before the error happens, Filer.Ancestor's value is NIL.

I am using :

Windows ME
Delphi 5 Professional Pack 1
ppJitPipeline
RBuilder 6.03 Std
Epson 777

Please, can you help me ?

When specifically does the error occur? What does the report look like? Do
you have any event handlers?

Hi Alexander,


At the time that the form with ppReport is created.


Like an invoice (a record and a detailband by page).



An event on "ppDetailBand1BeforeGenerate" creating
the invoice's numbers.

The other events are :

- Beforeprint
- PreviewFormCreate
- PrintDialogClose
- PrintingComplete
- StartPage


Regards,

Romano.
