My Visual Basic 2008 application, using Crystal Reports for reporting, has a new customer in Poland. The Polish regional setting in Windows lays out numbers with a space for the thousands separator, and a comma for the decimal separator (instead of the US English standard of comma and dot, respectively). For example, what with the US English setting displays as 1,234.56 displays with the Polish setting as 1 234,56 I'm developing and compiling the software on my US English machine.
For the most part, my CR reports display the numbers correctly using the machine's regional settings. However, I have a few numbers that for some reason are displaying using US English settings. In one report, all the detail values use the machine settings, while the sums in the report footer use US English. In another report, there are three fields that show up with US English, and dozens of others that use the machine settings.
I've looked thoroughly through the number formatting options for each field, and I don't see anything different. I'm not using the decimal separator or thousands separator custom formatting options, though I am using a custom setting for the number of decimals on almost all these fields (most are conditional, using a parameter sent to the report; a few are set to an explicit 3 decimals), both those working correctly and those not.
Any ideas on why the numbers are displayed inconsistently, and how to resolve it (short of changing every number field to use passed parameters for the separators rather than the machine settings)?
