Regional Options

Hello,

How can I change "Regional Settings" that in Control Panel
from Visual Basic. Regional Settings such as number appearance,
time format and so on ....

thanks

you can use the SetLocaleInfo api.

Here is sample code:

You can open the windows dialog and let the user make the changes themselves if you'd rather

VB Code:

'shows region settings tab
Shell "rundll32.exe shell32.dll,Control_RunDLL intl.cpl,,0"
 
' displays the Numbers property page
Shell "rundll32.exe shell32.dll,Control_RunDLL intl.cpl,,1"
 
'displays the Currency property page
Shell "rundll32.exe shell32.dll,Control_RunDLL intl.cpl,,2"
 
' displays the Time property page
Shell "rundll32.exe shell32.dll,Control_RunDLL intl.cpl,,3"
 
'displays the Date property page
Shell "rundll32.exe shell32.dll,Control_RunDLL intl.cpl,,4"
 
'displays the Locales property page (NT only)
Shell "rundll32.exe shell32.dll,Control_RunDLL intl.cpl,,5"
