How can I detect the OS language?

[Bongo]

Is there any possibility to detect on program start what
language is used on the running OS? (API...)

You can get all kinds of stuff from the regional settings. Here is an example. Play with it....

Private Declare Function GetLocaleInfo Lib "kernel32" Alias "GetLocaleInfoA" (ByVal Locale As Long, ByVal LCType As Long, ByVal lpLCData As String, ByVal cchData As Long) As Long
Private Declare Function SetLocaleInfo Lib "kernel32" Alias "SetLocaleInfoA" (ByVal Locale As Long, ByVal LCType As Long, ByVal lpLCData As String) As Boolean
Private Declare Function GetUserDefaultLCID% Lib "kernel32" ()
