In different parts of the world, there are different languages spoken and written. With this, a VBA programmer also faces language related issues while writing a VBA program. Here is a common date related problem solved which converts a date written in MM.DD.YYYY format into Excel standard date.
'This function converts a date from MM.DD.YYYY to system date format
Public Function ConvertToDate(strInputDate As String) As Date
'Variable Declaration
Dim iMonth As Integer
Dim iDay As Integer
Dim lYear As Long
'
'Get month from first 2 digits
If IsNumeric(Left(strInputDate, InStr(1, strInputDate, ".") - 1)) = True Then
iMonth = Left(strInputDate, InStr(1, strInputDate, ".") - 1)
Else
ConvertToDate = Null
Exit Function
End If
'Get day from input date
If IsNumeric(Mid(strInputDate, InStr(1, strInputDate, ".") + 1, 2)) = True Then
iDay = Mid(strInputDate, InStr(1, strInputDate, ".") + 1, 2)
Else
ConvertToDate = Null
Exit Function
End If
'Get year from last 4 digits
If IsNumeric(Right(strInputDate, 4)) = True Then
lYear = Right(strInputDate, 4)
Else
ConvertToDate = Null
Exit Function
End If
'Create a complete date and return the value
ConvertToDate = CDate(iDay & "-" & MonthName(iMonth) & "-" & lYear)
'
End Function
