Urgent! How to change the Regional setting???

This one is from MSDN



Step-by-Step Example
In a new or existing project, add a form (Form1).


Add a CommandButton (Command1) to the form.


Add the following code to the General Declarations section of Form1:

          Option Explicit

      Private Const LOCALE_SSHORTDATE = &H1F
      Private Const WM_SETTINGCHANGE = &H1A
      'same as the old WM_WININICHANGE
      Private Const HWND_BROADCAST = &HFFFF&

      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 PostMessage Lib "user32" Alias _
          "PostMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, _
          ByVal wParam As Long, ByVal lParam As Long) As Long
      Private Declare Function GetSystemDefaultLCID Lib "kernel32" _
          () As Long



Place the following code in Command1_Click event procedure:

      P  Private Sub Command1_Click()
         Dim dwLCID As Long
         dwLCID = GetSystemDefaultLCID()
         If SetLocaleInfo(dwLCID, LOCALE_SSHORTDATE, "dd-MMM-yy") _
            = False Then
            MsgBox "Failed"
            Exit Sub
         End If
         PostMessage HWND_BROADCAST, WM_SETTINGCHANGE, 0, 0
      End Sub



Run the program and open the form. Click on Command1 and then exit the program.


Go to Control Panel and double-click on the Regional Settings icon. Select the Date tab. Note that the Short date style has been changed to "dd-MMM-yy."

Hi thanks. But this is not the one I need.
Or the better way to describe my question is ...
       How can I know and change the windows system language (eg: from French to English US) in a multi-language support windows by using VB. Like the same thing we can do manually in Control Panel> Regional Settings>[select your target language].

I grabbed this from somewhere on the web (sorry I can not rememeber where exactly) - but it works well to display and set all the regional settings.

Hope this helps!

Try this:

In a module

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

Declare Function SetLocaleInfo Lib "kernel32" Alias _
"SetLocaleInfoA" (ByVal Locale As Long, ByVal LCType As Long, _
ByVal lpLCData As String) As Boolean

Declare Function GetUserDefaultLCID% Lib "kernel32" ()



Public Const LOCALE_SLANGUAGE = &H2


In your form

Public Sub Get_locale()
      Dim Clang As String
      Dim iRet1 As Long
      Dim iRet2 As Long
      Dim lpLCDataVar As String
      Dim Pos As Integer
      Dim Locale As Long
     
      Locale = GetUserDefaultLCID()


     
      iRet1 = GetLocaleInfo(Locale, LOCALE_SLANGUAGE, _
      lpLCDataVar, 0)
      Clang = String$(iRet1, 0)
     
      iRet2 = GetLocaleInfo(Locale, LOCALE_SLANGUAGE, Clang, iRet1)
      Pos = InStr(Clang, Chr$(0))
      If Pos > 0 Then
           Clang = Left$(Clang, Pos - 1)
           MsgBox "Regional Language is  " & Clang
      End If

End Sub

Public Sub Set_locale()

      Dim Nlang As String
      Dim iRet As Long
      Dim Locale As Long
     

      Locale = GetUserDefaultLCID() 'Get user Locale ID
      Nlang = "Put New Language here"
      iRet = SetLocaleInfo(Locale, LOCALE_SLANGUAGE, Symbol)
     
End Sub

Hi,

It doesn't work! please help again!

All the proposed solution above is to get the current locale GetUserDefaultLCID() and changing its' sub information SetLocaleInfo().

What I urgently need is to change the system default locale(language) without changing any sub information for that specific locale.

I would be much appreciate if somebody can help on this.

Regards.
