FIX: Code Pages Not Supported in All OS Languages at Run Time
ID: Q175900
|
The information in this article applies to:
- Microsoft FoxPro for Windows, versions 2.5a, 2.5b, 2.6, 2.6a
SYMPTOMS
In development mode, CPCURRENT() returns the correct value for a code page setting in the Config.fpw file. At run time, however, CPCURRENT() returns a value of zero (0) when the code page setting in the Config.fpw file is set to a value other than 437, 850, or 1252. This behavior also occurs when a run time application is executed on a non-English operating system and the code page is set to auto in the Config.fpw file.
STATUS
Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. This bug has been corrected in Visual FoxPro 3.x and Visual FoxPro 5.x.
MORE INFORMATION
When Windows starts, the international settings are determined by the values in the [intl] section of the Win.ini file. FoxPro for Windows uses the Microsoft Windows international settings on start up and overrides FoxPro's default settings.
A code page is a character set specific to an operating system or hardware platform. FoxPro uses code page information to translate between code pages so data is properly displayed and ordered. The manner in which data is ordered is determined by the collation sequence invoked with the SET COLLATE TO command. Use of data containing accented characters for any of the supported languages in an index necessitates setting the collation sequence to one of the alternate settings found in the topic SET COLLATE of the FoxPro Help file. Setting the collation sequence to a value other than "MACHINE" requires that "codepage=auto" be included in the Config.fpw file. FoxPro's default collation sequence is "MACHINE" and does not require a code page setting in the Config.fpw file.

Steps to Reproduce Behavior
- In a clean directory, create a project named CPTEST.
- Add a new program file named Cptest.prg.
Add the following code to the Cptest.prg file: '
*Begin Code
testval=CPCURRENT()
WAIT WINDOW STR(testval)
RETURN
*End Code - Save the program file and build an executable. In FoxPro 2.x for Windows, copy the support library file (.esl) file to the directory containing the Foxpro executable file.
Create a Config.fpw file in the same directory with the executable, containing one of the following lines: '
codepage=620
codepage=737
codepage=852
codepage=861
codepage=865
codepage=866
codepage=895
codepage=857
codepage=1250
codepage=1253
codepage=1254
codepage=10000
codepage=10006
codepage=10007
codepage=10029 - Exit FoxPro and run the executable using the Windows Run command.
