Save report with subreport in txt file

rbuser

Hello, first of all, sorry by my english.
I am new using reportbuilder.
I need to know if reportbuilder can save a report with subreports in a
txt file.
I have tried with a report without subreport and the txt file was
generated fine. But I have tried with a report with subreports and the
txt file was generated bad. The lines generated are in desorder. The
lines of two subreports appears mixedly, some lines of subreport 1 then
some lines of subreport 2, then some lines of subreport 1 again.
I don?t know, what can I try. I hope you can help me.

Thanks in advance.

Guillermo

Hi Guillermo,

Are you exporting to a delimited textfile or a Report Emmulation Textfile?
Exporting subreports to a delimited textfile is not natively supported in
ReportBuilder however you can work around this limitation by using the
method in the example below.

http://www.digital-metaphors.com/tips/PrintToPrinterAndTextFile.zip

If you are exporting to a Report Emmulation Textfile you will need to keep
in mind that everything in a text file is spaced on a character grid, rather
than in pixels. Take a look at the following article on printing to a
dot-matrix printer. The same concepts apply.

-----------------------------------------------
Tech Tip: Printing to Dot Matrix Printers
-----------------------------------------------

Dot matrix printers are natively line and character based. Most dot matrix
printers can emulate graphical (i.e. pixel based) printing, but there is
additional overhead which degrades printing speed.

Some options for maximizing performance:

1. Use native printer fonts.

Each dot matrix printer normally has some built-in fonts. You can choose
these fonts when using the ReportBuilder Report Designer. Choose File |
PageSetup and select the dot matrix printer (or optionally use the object
inspector to set Report.Printersetup.PrinterName). The fonts displayed in
Report Designer's font drop down list located on the format toolbar will
display the printer native fonts (indicated by a special printer icon next
to the font name).

2. Vertically position and size objects in 1/6 inch increments.

A standard dot matrix printer can print 66 lines per 11 inch portrait page.
This translates to a line height of 1/6 inch. Therefore the height of each
band should be a multiple of 1/6 as should the size of the margins, the
vertical position of each object etc.

Tip: When designing the report, use the PrinterSetup property to specify a
printer that contains 600 dpi. Then set Report.Units to PrinterPixels. Now
100 pixes = 1/6 of inch when specifying the positions of objects in the
layout.


3. Keep the layout simple, avoid using graphics of any kind.

Alternatives to using the dot matrix printer driver:

1. Use the generic text printer driver.

When using the generic text printer you will need to use the courier or
courier new font and apply the layout techniques described above.

2. Use ReportBuilder's ReportTextFile device output format.

This ReportTextFile device can exports the report to a .txt file which you
can then send to the printer. Demo dm0107.pas in the main reports demo app
shows an example of printing a report to a .txt file and previewing the
results.

Thank you for your soon answer.

The code that I am using is similar to the example, I will try with the
code of the example.

The solution that I developed is scanning each subreport and write the
contents in a file. There is not a better solution but is a solution.
If I can develop a better code I will expose here.

Thanks again.

Guillermo
