Calculate total pages

[MarcoBoschi]

How can I calculate number of pages in a print using for instance

PRINT oPrn NAME "My Print" PREVIEW

PAGE
WHILE !EOF()
some instruction like
Prn:Say( nRow, nCol , bla bla )

ENDPAGE
PAGE
ENDDO
ENDPAGE
ENDPRINT

does exist a clause that permits me to run the function without print anything only for calculate number of pages
it would be very simple

what do I know I imagine
PRINT oPrn NAME "My Print" CALCULATE
I execute two times the same function the firs is only for calculation the second really prints

have a nice day

I have the same problem on treport

Marco Boschi, I don't understand what you want to do exactly. Can you explain in more detail? Do you want to control page skipping?

Marco Boschi, no entiendo qué quieres hacer exactamente. ¿Puedes explicarlo con más detalle? ¿Quieres controlar el salto de página?

Gracias, thanks.

Regards, saludos.

Marco,
with the tprinter class it is easy to calculate the number of pages, just set how many rows you want per sheet and then divide the total archive with the rows and you will have the number of pages, but with the treport class I cannot do it, that is, it is displayed to me the page number but not the total number of pages and I can't know this before printing the pages.

Silvio, I don't understand, what is the reason for knowing in advance how many pages the report has? If it's not inconvenient, can you explain it to me?

Silvio, no entiendo, ¿cuál es la razón para saber de antemano cuántas páginas tiene el informe? Si no es inconveniente, ¿puedes explicármelo?

Gracias, thanks.

It is required for printing something like this in each page:

Page no. x of y

Enrico,
here's how I do it: I save an emf file and then reopen add the number and print it.
I use it for invoice copies, I print the invoice number on the emf and then print on paper.
Strictly speaking, regenerating from data is not a copy. In terms of financial regulations,
a blueprint is considered a copy.
Best regards,
Otto

How to do that exactly? Can you share it?

Enrico,
I have extended TPrinter.

Than you, but I can't find nothing related to total number of pages, or I am missing it. Can you explain?

[Otto]

Enrico, I use it for a different purpose. But you only need to count the number of EMF files per document.
Then you can print the pages and write whatever you want on them as if on a layer.
Best regards,
Otto

[Enrico Maria Giordano]

Thank you. It is not worth the work, at least for me.

[Marc Venken]

For TPrinter there is :

* New: Method GetPages() on class TPrinter to get the From & To pages
selected on the print dialog when the FROM USER clause is used.
This method returns a two dimension array but also you can pass the
nFrom and nTo variables by reference, for example:

aPages := oPrn:GetPages(@nFrom, @nTo)

It is required for printing something like this in each page:

Page no. x of y

Mister Otto, any practical example of this madness you posted?

Señor Otto, ¿algún ejemplo práctico de esta locura que publicó?

Gracias, thanks.
