Handling Version Numbers (Major.Minor.Build.Plateform)

[Birky]

Can someone point me in the right direction on how to use Version Numbers within Access? I have a database were its primary goal is to track the versions of several projects. Since the version numbers are formatted as Major.Minor.Bui ld.Plateform (1.01.01.01) I am unable to find a way to sort and or automatically update the version to the next appropriate version number. I was hoping someone could point me to some literature on best practices on how to deal with these types of numbers within Access.

Any help would be greatly appreciated.

Thanks
Birky

This would be the general idea:
[CODE=vb]
Dim strVerNumber As String
Dim strNewVerNumber As String

'Retrieve the last Version Number for a specific ProjectID (1.01.01.01)
strVerNumber = DLast("[Version]", "tblVersionNumb ers","[ProjectID] = " & <Project ID>)

'Let's say you wanted to increment the Minor Version Number (Major Version between 1 and 9)
strNewVerNumber = Left$(strVerNum ber, 2) & Format$(Val(Mid $(strVerNumber, 3, 2)) + 1, "00") & _
Right$(strVerNu mber, 6)

Debug.Print strNewVerNumber[/CODE]
OUTPUT:
[CODE=text]1.02.01.01[/CODE]

Thanks for the information but I was able to extract the needed information by using the below code.

    Dim i As Integer
    
    output_prefixStr = ""
    output_suffixStr = ""
    
    If Not IsNull(input_inStr) Then
        ' inStr has something, so parse it
        If InStr(1, input_inStr, ".", vbTextCompare) = 0 Then
            ' inStr has no dot, so suffix=inStr, and we're done
            output_suffixStr = input_inStr
        Else
            ' inStr has at least one dot, so find position of rightmost dot
            i = Len(input_inStr)
            While InStr(i, input_inStr, ".") = 0 And i > 0
                i = i - 1
            Wend
            ' set prefixStr as all text left of dot, and suffixStr as all text right of dot
            output_prefixStr = Left(input_inStr, i - 1)
            output_suffixStr = Right(input_inStr, Len(input_inStr) - i)
        End If
    End If

Thanks again
