[AccessD] Detecting External References From With-In an MDE?

 Yea, that lists the reference made from within the database, but what I
need is to "Detect" references (external connections) to the mde.

 Does this make any sense?

Here is one method, filling a table:

<code>

Option Compare Database
Option Explicit

' Declarations and functions for creating and storing
' a list (table) of the current References.
'
' 2001-08-20. Cactus Data ApS, CPH.

  ' Length of GUID string per definition.
  Private Const clngGUID                As Long = 38

  Type GuidDefinition
    Guid As String * clngGUID
    Major As Integer
    Minor As Integer
  End Type

  ' Minimum Guid version.
  Private Const cintMajorMinVersion     As Integer = 1
  Private Const cintMinorMinVersion     As Integer = 0

  Private Const cstrReferencesTableName As String = "USysReferences"
  Private Const cintLocalTable          As Integer = 1


Public Function CreateTableReferences() As Boolean

  Dim strSQL As String

  On Error Resume Next

  ' Create, without using DAO, table cstrReferencesTableName.
  strSQL = vbNullString & _
    "CREATE TABLE " & cstrReferencesTableName & " " & _
      "(" & _
        "GuidString TEXT(38), " & _
        "Major SMALLINT, " & _
        "Minor SMALLINT, " & _
        "Name TEXT(255) NOT NULL, " & _
        "FullPath TEXT(255), " & _
        "MajorMin SMALLINT, " & _
        "MinorMin SMALLINT, " & _
        "CONSTRAINT idxGuid PRIMARY KEY (GuidString)" & _
      ")" & _
    ";"

  DBEngine(0)(0).Execute (strSQL)

  CreateTableReferences = (Err = 0)

End Function


Public Function PopulateTableReferences( _
  Optional ByVal booDisableLowerGuidVersions As Boolean) _
  As Boolean

  Dim ref     As Reference
  Dim strSQL  As String

  ' If booDisableLowerGuidVersions is True, minimum values for Guid version
  ' will be set equal to current Guid version.
  ' If booDisableLowerGuidVersions is False, minimum values for Guid version
  ' will be set as defined by the global variables:
  ' cintMajorMinVersion
  ' cintMinorMinVersion

  On Error Resume Next

  ' Empty, without using DAO, table cstrReferencesTableName.
  strSQL = "DELETE * FROM " & cstrReferencesTableName & ";"
  DBEngine(0)(0).Execute (strSQL)

  ' Populate, without using DAO, table cstrReferencesTableName.
  For Each ref In References
    With ref
      strSQL = vbNullString & _
        "INSERT INTO " & cstrReferencesTableName & " " & _
          "VALUES(" & _
            "'" & .Guid & "', " & _
            "" & .Major & ", " & _
            "" & .Minor & ", " & _
            "'" & .Name & "', " & _
            "'" & .FullPath & "', " & _
            "" & IIf(booDisableLowerGuidVersions, .Major,
cintMajorMinVersion) & ", " & _
            "" & IIf(booDisableLowerGuidVersions, .Minor,
cintMinorMinVersion) & "" & _
          ")" & _
        ";"
      DBEngine(0)(0).Execute (strSQL)
    End With
  Next

  Set ref = Nothing

  PopulateTableReferences = (Err = 0)

End Function

</code>

You can easily reduce it to just run a Debug.Print list if you wish.
