excel - Using VBA to detect which decimal sign the computer is using

Question

Is it possible to use VBA to detect which decimal sign is being used on the computer?

I have a macro script that adds a conditional formatting to an excel sheet. The problem is that the target computers might use both decimal signs. So I want to make the script work for all computers.

The code looks like this:

With range("D" & row)
    .FormatConditions.Delete
    .FormatConditions.Add Type:=xlCellValue, Operator:=xlNotBetween, Formula1:="=1,01*$C$" & row, Formula2:="=0,99*$C$" & row
    .FormatConditions(1).Font.ColorIndex = 3
End With

Regarding the answer above, it is important to know that Application.DecimalSeparator and Application.International(xlDecimalSeparator) do not behave the same way:

• Application.DecimalSeparator will ALWAYS output the decimal separator chosen in Excel options even when Excel is told to use System Separators (from Windows regional settings)
• Application.International(xlDecimalSeparator) will output whatever is the actual decimal separator used by Excel whether it comes from Windows settings (when Application.UseSystemSeparators = True) or from Excel options (when Application.UseSystemSeparators = False)

I therefore strongly recommend to always use Application.International(xlDecimalSeparator).
