Hi,
I'm Vince. I'm developing a small application in MS Access for a German client. In India we use "." for decimal places and "," for group separators. But in Germany it is different like they use "," for decimal places and "." for group separators. we have coded the application, without taking German practice into the consideration. Now the problem comes when the client started using the application and entering the decimal places. The application is saving the numbers " 0.66" as "66" and "1.66" as "166". That is it is not considering the "." as decimal. But the client now want to enter only "." as decimal but want to see "," in place of decimal i.e. he will enter "1.66" and want to see as "1,66" on the front end. While doing so, the regional settings need to be changed, for which client is not ready. Can you please tell me how can I solve this problem without changing his regional setings (numbers). If changing regional settings is the only solution, how can I do that using API calls? And at the closing of the application, his old regional settings should be back.

I don't think changin the local settings would be an option because this would also change the settings for any other program he might be useing.
You could read his settings and then convert his data.
Here is an example:
Add a listview called ListView1 to a form
And add a class called CLocale to your project
Copy the following code in form1
Code:
Option Explicit
Private Sub Form_Load()
Dim CLocale As CLocale
Dim xLI As ListItem
Set CLocale = New CLocale
ListView1.View = lvwReport
ListView1.ColumnHeaders.Add , , "Name"
ListView1.ColumnHeaders.Add , , "Value"
CLocale.ReadSettings [System Default Locale]
Set xLI = ListView1.ListItems.Add(, , "SYSTEM SETTINGS")
xLI.SubItems(1) = "SYSTEM SETTINGS"
Set xLI = ListView1.ListItems.Add(, , "")
Read CLocale
Set xLI = ListView1.ListItems.Add(, , "")
CLocale.ReadSettings [User Default Locale]
Set xLI = ListView1.ListItems.Add(, , "USER SETTINGS")
xLI.SubItems(1) = "USER SETTINGS"
Read CLocale
Set CLocale = Nothing
End Sub
Private Sub Read(ByVal CLocale As CLocale)
Dim xLI As ListItem
Set xLI = ListView1.ListItems.Add(, , "DateSeparator")
xLI.SubItems(1) = CLocale.DateSeparator
Set xLI = ListView1.ListItems.Add(, , "TimeSeparator")
xLI.SubItems(1) = CLocale.TimeSeparator
Set xLI = ListView1.ListItems.Add(, , "Short Date")
xLI.SubItems(1) = CLocale.DateFormatShort
Set xLI = ListView1.ListItems.Add(, , "Long Date")
xLI.SubItems(1) = CLocale.DateFormatLong
Set xLI = ListView1.ListItems.Add(, , "Time Format")
xLI.SubItems(1) = CLocale.TimeFormat
Set xLI = ListView1.ListItems.Add(, , "DecimalSepartor")
xLI.SubItems(1) = CLocale.DecimalSeparator
Set xLI = ListView1.ListItems.Add(, , "ThousandSepartor")
xLI.SubItems(1) = CLocale.ThousandSeparator
Set xLI = ListView1.ListItems.Add(, , "EnglishCountryName")
xLI.SubItems(1) = CLocale.EnglishCountryName
Set xLI = ListView1.ListItems.Add(, , "LocalCountryName")
xLI.SubItems(1) = CLocale.LocalCountryName
Set xLI = ListView1.ListItems.Add(, , "CountryCode")
xLI.SubItems(1) = CLocale.CountryCode
Set xLI = ListView1.ListItems.Add(, , "DefaultLanguage")
xLI.SubItems(1) = CLocale.DefaultLanguage
Set xLI = ListView1.ListItems.Add(, , "MetricSystem")
Select Case CLocale.MetricSystem
Case [S.I. Metric system]
xLI.SubItems(1) = "[S.I. Metric system]"
Case [U.S. Metric system]
xLI.SubItems(1) = "[U.S. Metric system]"
'End Case
End Select
Set xLI = ListView1.ListItems.Add(, , "MonetarySymbol")
xLI.SubItems(1) = CLocale.MonetarySymbol
End Sub
And add the following code to the class named CLocale
Code:

I know its kinda big, but i hope it helps.
