Automation?

Hi, I am trying to see if there is a way to use automation to get the object of the Control Panel so that I can change Regional/Language settings within my programm (assign this action to a button).

As word and excel allow programmers to have Application isntances, is there a COntrol panel isntance or Explorer instance?


Thanks. Appreicate any comments or suggestions.

Control panel modules are not COM, so they do not automate.

They have the extension .cpl

You call rundll32 to activate them (shell)

Code:

---

command:  rundll32.exe shell32.dll,Control_RunDLL intl.cpl,,0
result:  displays the Regional Settings property page
     
command:  rundll32.exe shell32.dll,Control_RunDLL intl.cpl,,1
result:  displays the Numbers property page
     
command:  rundll32.exe shell32.dll,Control_RunDLL intl.cpl,,2
result:  displays the Currency property page
     
command:  rundll32.exe shell32.dll,Control_RunDLL intl.cpl,,3
result:  displays the Time property page
     
command:  rundll32.exe shell32.dll,Control_RunDLL intl.cpl,,4
result:  displays the Date property page
     
command:  rundll32.exe shell32.dll,Control_RunDLL intl.cpl,,5
result:  displays the Locales property page (NT only)

Thank you, jim. Although this is a VERY useful piece of code, this gives me no options to change withing the Regional Settings. I would want to change the settings inside the REGional Settings (RS) and possible run this in the background so that user have no idea about the actual process.

As you mentioned the Control Panel are not COM objects, however as I understand the control panel Applets are something like a DLL packet ito a *.cpl extension. I am thinking if I can call the functions within this cpl file, but i cant find a way.

Actually another thing : Can I use Shell Instance to try and get some properties changed this way (still talking about RG settings), you can see I am not very intimate with Win32 API at this point. :)

Please let me know if you have any ideas. Appreciate your help.

There is an application called Kira which I downloaded from Planet-Source-Code once, which did a lot of system setting changes. That might do the trick for you.

Thanks Aidan I like the program, but unfortunately its does not have anything on regional settings.

Randy Birch has some stuff on setting dates and some other locale information using SetLocaleInfo

http://www.mvps.org/vbnet/code/locale/setlocaleinfo.htm

You know it would help if you told us exactly what you are trying to set, because the api functions for a given control panel are really a bunch of different things -

Registry settings, mostly
codepage setting for the keyboard
Date & time formats
Number formats
etc.

Thanks jim
I am trying to change EVERYTHing (date format, time, language ane etc). So for example if your language is English I want to set it to say French. I Have found functions like setThreadLocale (win32 API) but I am having difficulty calling them through VB with the right Parameters and everythig.

REason : I want to run a program with one language setting and then change languge and run it in another lang setting

<code>
Private Declare Function SetThreadLocale Lib "kernel32" _
(ByVal LCID As Long) As Boolean

Dim LS As Boolean
LS = SetThreadLocale (MakeLCID(MakeLangID (0419,Sublang_Neutral), Sort_DEfault)
</code>

For some reason the MAkeLangID is not recognized. I am thinking its an API C++ call and not VB.

UDDATE : THANKS FOR THE LINK.
