Hi,
I have strange problem, I have application on Windows 2012 Server,
where is set locale to Slovak (DecimalSeparator is comma)
In my application in DataModuleCreate I explicitly set
FormatSettings.DecimalSeparator='.' (dot)
All works as expected (decimal numbers are formated with "dot"), but
after some time (hours) when application runs, DecimalSeparator
changes back to "comma" ?
Is it possible ?
AFAIK International settings are initialised once in sysutils
initialization section, or are they reevaluated later ?
They are initialized once in FPC.
But there is a windows message that notifies applications when the
settings change:
http://stackoverflow.com/questions/7385357/window-message-notification-language-and-locale
Maybe lazarus picks it up.
Thank you Michael,
it is exactly so.
Lazarus catch WM_SETTINGCHANGE and calls Application.IntfSettingChange
which calls GetFormatSettings in SysUtils
It can be switched off by setting Application.UpdateFormatSettings:=False;
Interesting ...
Thanks
-Laco.
