Par2: Dynamically setting report band properties 1998-06-22 -- Markku Niskanen I did a hard job changing the report band dimensions
during runtime and this is how I did it. Anybody with
a more elegant solution please feel free to send your
comments here. The hardest things were
a) Finding the correct embed point
b) Finding a way to hit the target band
c) Finding my cigarettes under the pile of test sheets.
First I gave the bands proper equate labels: ?Header1,
?Detail1 and ?Footer1 so that I could use them a bit later.
I also created global variables that I filled with the proper height
values from thi INI file. My report was written in millimeters and
the paper size was A4 (210x297mm) so this is where the '297'
comes from.
I used the ThisWindow.OpenReport Procedure and added
the following code right after the optional translations (comments
and extra material clipped):
ThisWindow.OpenReport PROCEDURE()
ReturnValue BYTE,AUTO
CODE
ReturnValue = PARENT.OpenReport()
IF ~ReturnValue
Translator.TranslateWindow(SELF.Report)
END
! [Priority 8800]
! This is where my code starts
SetTarget(SELF.Report,?Header1)
Report$?Header1{prop:height} = GLO:TopMargin
SetTarget(SELF.Report,?Detail1)
Report$?Detail1{prop:height} = GLO:LabelHeight
Report$?Footer1{Prop:Ypos} = GLO:FooterY
Report$?Footer1{Prop:Height} = 297 - Report$?Footer1{Prop:Ypos}
SetTarget(SELF.Report)
Target{prop:Ypos} = GLO:TopMargin
Target{prop:height} = GLO:LabelsY * GLO:LabelHeight
SetTarget ! Reset the target
There are two weird things. For some reason I had to Set SELF.Report
as the target LAST, otherwise the report height got a funny value from
one of the band heights set earlier.
The second funny thing is that this WORKED
