Hi,

I need to transform PrintingDevice:PaperWidth to twips. I'm getting 2100
(for A4) so in my case it is mesured in 10ths of mm. Does it return
always a metric value, or is dependent on some OS definition? if so, how
can I know if PaperWidth is mesured using Imperial or Metric system?

Thanks for any hint

----------
1.Use the GetLocaleInfo function (defined in the Microsoft Windows SDK
documentation) to retrieve the default system locale. Use
LOCALE_SYSTEM_DEFAULT for the first parameter, Locale, and
LOCALE_ICOUNTRY for the second parameter, LCType.

2.Use the default system locale obtained from GetLocaleInfo to
determine metric or non-metric paper size.
◦Non-metric if default system locale is:
■CTRY_UNITED_STATES, or
■CTRY_CANADA, or
■Greater than or equal to 50, but less than 60 and not CTRY_BRAZIL, or
■Greater than or equal to 500, but less than 600

or metric otherwise.

Hi Ronny,

This is a surprise as in the meanwhile I've read somewhere that printers
always return paper size in tenths of mm. I'll check it further, thanks.

Carlos,

Yes, you are right, it's in 1/10 millimeter.

--- DEVMODE ----
ex. : dmPaperLength, dwPaperWidth, etc....
For printer devices only, overrides the length of the paper specified
by the dmPaperSize member, either for custom paper sizes or for
devices such as dot-matrix printers that can print on a page of
arbitrary length. These values, along with all other values in this
structure that specify a physical length, are in tenths of a
millimeter.
-----

But I (mis)understood that you wanted to know if the measured
millimeters came from a printer in a country where a metric or non-
metric/imperial format is preferred.

Ronny.
