How can I change page dimensions in code?

rbuser

I have a client who requires to print some text on one of four labels on an
A4 sheet.

The label (clear) is then stuck onto a Taxi Licence Plate (e.g. like you see
on the back of a licensed taxi).

I would like the screen preview to show the end result e.g. show a taxi
plate with logos, etc. and therefore wish to set the page dimensions to the
size of the plate.

However, just before printing to the printer, I need to change the page
dimensions to A4, then ask the user which of the 4 labels to print on.

I have managed everything in RAP code EXCEPT the ability to change the page
dimensions. I am doing most of this in the ReportOnPrintDialogCreate event -
is this too late to change the page dimensions? If so, where should I do it
instead?

As always, you help would be much appreciated.

P.S. If you are interested in my code for displaying a user-input form with
a user-definable TGrid that returns the user-selected column and row number,
please let me know. Other may find it helps to get them started!

Hi,

one way is to create four subreports with the correct page sizes and
just load the needed subreport based on the users choice.

enjoy,
Ron.

Thanks for the thought but I fear this would be a bit too hard for an
end-user to modify easily.

The same method would also be used for printing driver identity badges - but
they can have 8 or even 16 labels per sheet - this would need a lot of
subreports!

I'm after something easy I can do in RAP code and which is dependent on the
end-user setting the page size and the number of labels available on the A4
sheet (in code).

Any more suggestions?

You could code a RAP pass through function to get the paper name from what
the user has selected.

In the RAP Report BeforePrint event handler you can say
Report.PrinterSetup.PaperName := MyPassThruGetPaperName;

There are pass through function tutorials in the installed RAP demos
directory.
