What is the best way to print (large) memo fields?

[Maarten Roos]

Hello all,
I am using the demo version to build a little application to convince my
selves and my boss to use Xailer in order to convert our old clipper
applications. I am wondering what is the best way to print memo fields? How
do I determine how many lines to print so I can stop printing (if necessary)
and go on to the next page and continue? You had with clipper mlcount and
memoline, you have now also, but what is the number of characters per line
or is there another (better) way to print large text fields?
Thx
Maarten

Maarten,
Is not an easy task if you are using a proportional font, but you can use
the method TCanvas:DrawRichEdit() to do the job.
BTW if you use a non proportional font like Courier then the functions
mlcount() and memoline() can be used.

Ignacio,
thank you for the answer.
I will try it with TCanvas:DrawRichEdit() otherwise i will do the good old
mlcount and memoline!
Also, how do you handle large memo fields with the report generator?
Probably not?

Maarten,
From the Xailer report generator you can do the following trick (with
non-proportional fonts):
1) Define a column with the desired width that prints only the first
memoline() of your memo field
3) On the event TReport:OnChange print the rest of lines with this pseudo
code:
DO WHILE nCurrentLine <= nTotalLines
WITH OBJECT oReport
:StartLine()
:PrintAtCol( nColOrder, Memoline( cText, nCurrentLine ++ ), ... )
:EndLine()
EN WITH
ENDDO
