Hi,
For Open Box you can use following code:

Private Sub Command0_Click()
   Dim strFilter As String
    Dim strInputFileName As String

    strFilter = ahtAddFilterItem(strFilter, "Access Files (*.mdb)", "*.MDB")

    strInputFileName = ahtCommonFileOpenSave(Filter:=strFilter, OpenFile:=True, InitialDir:="", _
                    DialogTitle:="Please select 007_Datenbank...", _
                    Flags:=ahtOFN_HIDEREADONLY)


End Sub

This will open a dilogue box for .mde file.
You can edit the same for .xls or other file extentions.

But if you are planing to import that file in your database than you need to write additional codes for the same.
I can give you a sample code which you may edit:
I wanted to import File named as "CHANNEL ASSIGNMENT (Dont replace or rename this file)" from some database in my L:/ drive to my table
"009_CHANNEL ASSIGNMENT (Dont replace or rename this file)" in my current working database. I also specified which columns to be copied in which. Code works very smoothly if tables are not renamed.
Write this code in a button:


If MsgBox("Existing Table will be Deleted. Do You wish to continue?", 1) = 1 Then
    Dim strFilter As String
    Dim strInputFileName As String

    strFilter = ahtAddFilterItem(strFilter, "Access Files (*.mdb)", "*.MDB")

    strInputFileName = ahtCommonFileOpenSave(Filter:=strFilter, OpenFile:=True, InitialDir:="", _
                    DialogTitle:="Please select 009_CHANNEL ASSIGNMENT (Dont replace or rename this file)...", _
                    Flags:=ahtOFN_HIDEREADONLY)
    If Right(strInputFileName, 4) = ".mdb" = False Then
    End
End If

    If TabVorhanden("009_CHANNEL ASSIGNMENT (Dont replace or rename this file)") = True Then
        DoCmd.Echo True, "Deleting temporary 009_CHANNEL ASSIGNMENT (Dont replace or rename this file)..."
        DoCmd.DeleteObject acTable, "009_CHANNEL ASSIGNMENT (Dont replace or rename this file)"
    End If

    DoCmd.TransferDatabase acImport, "Microsoft Access", strInputFileName, acTable, "009_CHANNEL ASSIGNMENT (Dont replace or rename this file)", "009_CHANNEL ASSIGNMENT (Dont replace or rename this file)"


    Dim AKTUELLEDB As Database, i As Recordset, W As Recordset
    Set AKTUELLEDB = DBEngine(0)(0)
    Set i = AKTUELLEDB.OpenRecordset("009_CHANNEL ASSIGNMENT (Dont replace or rename this file)", DB_OPEN_SNAPSHOT)
    Set W = AKTUELLEDB.OpenRecordset("CHANNEL ASSIGNMENT (Dont replace or rename this file)", DB_OPEN_DYNASET)
    Dim i_int As Integer

    DoCmd.SetWarnings False
    DoCmd.RunSQL "DELETE * FROM [CHANNEL ASSIGNMENT (Dont replace or rename this file)];"
    DoCmd.SetWarnings True

    DoCmd.Echo True, "Converting 009_CHANNEL ASSIGNMENT (Dont replace or rename this file) in CHANNEL ASSIGNMENT (Dont replace or rename this file)..."
    i.MoveFirst
    Do
            W.AddNew
            W![KKS] = i![KKS]
            W![Signal Name] = i![Signal Name]
            W![CABINET] = i![CABINET]
            W![Channel] = i![Channel]
            W![REDUNDANCY] = i![REDUNDANCY]
            W![STD HARDWARE PLAN] = i![STD HARDWARE PLAN]
            W.Update
        i.MoveNext
    Loop While i.EOF = False

    i.Close
    W.Close

    DoCmd.Echo True, "Transfering Database to " & strInputFileName & "..."

    DoCmd.TransferDatabase acExport, "Microsoft Access", strInputFileName, acTable, "CHANNEL ASSIGNMENT (Dont replace or rename this file)", "CHANNEL ASSIGNMENT (Dont replace or rename this file)"

    'DoCmd.OpenTable "CHANNEL ASSIGNMENT (Dont replace or rename this file)", acViewNormal
    'DoCmd.Maximize

    If TabVorhanden("009_CHANNEL ASSIGNMENT (Dont replace or rename this file)") = True Then
        DoCmd.Echo True, "Deleting temporary 009_CHANNEL ASSIGNMENT (Dont replace or rename this file)..."
        DoCmd.DeleteObject acTable, "009_CHANNEL ASSIGNMENT (Dont replace or rename this file)"
    End If


    MsgBox "Conversion ready! Database transfered to '" & strInputFileName & "'.", vbInformation
    End
End If


Also with this you will need to define above variables, make two modules named : "Open/Save Dialog box" and "Dienstprogramme"

[u]For "Open/Save Dialog box" Past foll code without editing:</u>

[u]And for "Dienstprogramme" module past:</u>
Function TabVorhanden(Tabellenname As String) As Boolean
    Dim db As DAO.Database
    Dim tdf As DAO.TableDef
    Set db = CurrentDb
    For Each tdf In db.TableDefs
        If tdf.Name = Tabellenname Then TabVorhanden = True: Exit For
    Next
End Function

Thats it offf... Huge thing for just importing some silly data, but its necessary...
Hope it works for you. Do let me know.

Regards,
Durgesh
