Hi Experts,
I need help parsing a string in my VB6 application.  I have a list of names formatted in the following manner:  

Jones, Martha
Smith, Olivia R

I want to parse  the name so that the LAST NAME, FIRST NAME, and Middle Initial are placed in the following 3 variables:  strLastName, strFirstName, strMiddleInit (if it is there).  How can I do this?

Thanks in advance,

This should come close
Dim oRE as object
Dim oMatches as object
Dim oM as object      'only needed if passing a lot of names at once
Dim strWholeName as string
Dim strLastName as string, strFirstName as string, strMiddleInit as string

set oRE = createobject("vbscript.regexp")
oRE.Global = True
oRE.pattern = "(.*?), ([^ ]*) ?(.*)"
strWholename = "Jones, Martha"
if oRE.test(strWholename) THen
   set oMatches = oRE.Execute(strWholename)
   strLastName = oMatches(0).submatches(0)
   strFirstName = oMatches(0).submatches(1)
   strMiddleInit = oMatches(0).submatches(2)
End If

strWholename = "Smith, Olivia R"
if oRE.test(strWholename) THen
   set oMatches = oRE.Execute(strWholename)
   strLastName = oMatches(0).submatches(0)
   strFirstName = oMatches(0).submatches(1)
   strMiddleInit = oMatches(0).submatches(2)
End If

Here is a way with a bit less code:
Dim strParts() As String
    Dim strSurname  As String
    Dim strFirstName  As String
    Dim strMiddle  As String
    strParts = Split(Replace(strFullName, ",", ""), " ")
    strSurname = strParts(0)
    strFirstName = strParts(1)
    If UBound(strParts) > 1 Then
        strMiddle = strParts(2)
    End If

Here's some strait forward code doing simple InStr searches and basic Left, Mid, and Len functions:
Dim I as Integer
I = InStr( strFullName "," )
If I > 0 Then
    strLastName = Left$( strFullName, I - 1 )  'Save Last Name    

    strFullName = Trim$(Mid$( strFullName, I + 1 ))  'Update Name to just 1st and MI

    I = InStrRev( strFullName, " " )
    If I > 0 Then
        strMiddleInit = Mid$( strFullName, I + 1 )

        'Check for double 1st names (i.e. name with a space, yet no middle initial
        If Len( strMiddleInit ) > 1 Then
            strMiddleInit = ""
            strFirstName = strFullName 
            strFirstName = Left$( strFirstName, Len( strFullName ) - 2 )
        End If
        'No Middle Initial
        strFirstName = strFullName
        strMiddleInit = ""
    End If
End If

comment on http:#a40006099 - Graham's code
* if you have a double last name (not hyphenated), the parse will not be correct.  Think of Spanish family names.
* a correct version of Graham's code would not use the Replace() function, instead splitting on the ", " delimiter first and any remaining space delimiter second.
    strParts = Split(strFullName, ", ")
    strSurname = strParts(0)
    strParts = Split(Trim(strParts(1)), " ")
    strFirstName = strParts(0)
    If UBound(strParts) > 0 Then
        strMiddle = strParts(1)
    End If

comment on http:#a40006639 - HooKooDooKu's code
* if someone has a double first name, would we expect them to also have a middle initial?
* I do like your check for a single character middle initial.  It has caused me to rethink my regex pattern.  This pattern should handle multiple first names with a middle initial
^(.*?), \b(.*?)\b(.{0,1}?)$

If you need something more robust, you might give this a spin:

It's not perfect, of course, and some edge cases will cause it to return unexpected results.
