• Microsoft Jet OLE DB 4.0

    • Delimited columns

      Provider=Microsoft.Jet.OLEDB.4.0;Data Source=c:\txtFilesFolder\;
      Extended Properties

      The delimiter can be specified in the registry at the following location:
      HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Jet \ 4.0 \ Engines \ Text
      "Format" = "TabDelimited"
      "Format" = "Delimited(;)"

    • Fixed length columns

      Provider=Microsoft.Jet.OLEDB.4.0;Data Source=c:\txtFilesFolder\;
      Extended Properties

      "HDR=Yes;" indicates that the first row contains columnnames, not data. "HDR=No;" indicates the opposite.

      To specify each columns length use the Schema.ini file. See description below.

      Important note!
      The quota " in the string needs to be escaped using your language specific escape syntax.
      c#, c++   \"
      VB6, VBScript   ""
      xml (web.config etc)   "
      or maybe use a single quota '.
