I have an application I am building in Excel which I believe will be migrated to SQL or Access in the future. I am using Worksheets as Tables and need to assign unique ID's in a number of places. I would like to use GUIDs from inception so as to simplify the migration process as much as possible. Can Excel of VBA auto create GUIDs?

or if you don't feel like checking that, use this code:

Declare Function CoCreateGuid_Alt Lib "OLE32.DLL" Alias "CoCreateGuid" (pGuid _
    As Any) As Long
Declare Function StringFromGUID2_Alt Lib "OLE32.DLL" Alias "StringFromGUID2" _
    (pGuid As Any, ByVal address As Long, ByVal Max As Long) As Long

Function CreateGUID() As String
    Dim res As String, resLen As Long, guid(15) As Byte
    res = Space$(128)
    CoCreateGuid_Alt guid(0)
    resLen = StringFromGUID2_Alt(guid(0), ByVal StrPtr(res), 128)
    CreateGUID = Left$(res, resLen - 1)
End Function
Or, more simply:

    Set oTypeLib = CreateObject("Scriptlet.TypeLib")
    szMyGuid = oTypeLib.Guid
    Set oTypeLib = Nothing



A quick download of the Class Module and a quick code edit and I'm done! You are a rockstar! Thank you.

thanx for the points and happy coding!
