ABC: Resizing report details
1998-06-22 -- Markku Niskanen
 
Newsgroups: topspeed.products.c4 Whew! 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 . Markku
