I have huge text file and I want to export it to database
I have text(row) delimiters ///
I probably want 3 fields  1.identity-number 2.name-first line of text following ///  3.actual data between ///...///
Suppose I open file and save it into variable(variant), it is huge
Can I parse variant
using InStr Left and right functions
What is your best solution to this
Access and MSSQL data transformation services cannot understand
/// delimiters.

You can use the following function :

Public Function GetTokens(sTxt As String, sToken As String) As Variant
   ' *** Returns an array to tokenized values
   ' ***  Ex:  GetTokens("Field1///Field2///Field3///", "///") = ({ "Field1", "Field2", "Field3" })

    Dim iTokenLen As Integer
    Dim iTokenCnt As Integer
    Dim lOffset As Long
    Dim lPrevOffset As Long
    Dim aTokens() As String

    iTokenLen = Len(sToken)
    lOffset = InStr(sTxt, sToken)
   
    Do While lOffset > 0
        ReDim Preserve aTokens(iTokenCnt)
        If lOffset - lPrevOffset > 1 Then
            aTokens(iTokenCnt) = Mid$(sTxt, lPrevOffset + 1, lOffset - 1 - lPrevOffset)
        Else
            aTokens(iTokenCnt) = ""
        End If
       
        lPrevOffset = lOffset
        lOffset = InStr(lOffset + iTokenLen, sTxt, sToken)
        iTokenCnt = iTokenCnt + 1
    Loop
   
    ReDim Preserve aTokens(iTokenCnt)
    aTokens(iTokenCnt) = Mid$(sTxt, lPrevOffset + 1)
    GetTokens = CVar(aTokens)

End Function
