Step 4: Populate the Details Text Box

To populate the Details text box

Create a new subroutine named recFields and insert the following code:

Sub recFields(r As Record, l As ListBox, t As TextBox)
    Dim f As Field
    Dim s As Stream
    Set s = New Stream
    Dim str As String
    
    For Each f In r.Fields
        l.AddItem f.Name & ": " & f.Value
    Next
    t.Text = ""
    If r!RESOURCE_CONTENTCLASS = "text/plain" Then
        s.Open r, adModeRead, adOpenStreamFromRecord
        str = s.ReadText(1)
        s.Position = 0
        If Asc(Mid(str, 1, 1)) = 63 Then '//63 = "?"
            s.Charset = "ascii"
            s.Type = adTypeText
        End If
        t.Text = s.ReadText(adReadAll)
    End If
End Sub

This code populates lstDetails with the fields and values of the simple record passed to recFields. If the resource is a text file, a text Stream is opened from the resource record. The code determines if the character set is ASCII and copies the Stream contents into txtDetails.
