adding data to a linked file through access RRS feed

  • Question

  • Is it possible to add/amend records through access to a linked file. I am trying this with an html file, but it only seems to work one way. I can only add the records through the html file.

    This is not for anything specific, I am just trying playing around with access and testing its limitations and functionality.

  • Hi,

    I've never tried linking a HTML file with Access but maybe linking to a Text file, like a HTML file only produces a "read-only" copy of the data. I know this is the case with linked Excel spreadsheets.

    If so, the only way to update the HTML file from Access would be to use code to manipulate the file itself.

    Just my 2 cents...

  • No, some of the drivers such as Text and HTML, are not true DBMS so the drivers that are provided have read-only capability. Other linked files, such as those you can connect through using a fully compliant ODBC driver, would be more likely to have update capability.

  • Hello,

    As theDBguy suggested, the only way to update would be updated the HTML itself, so you could create macros to update the HTML file.

    The following code could insert a new record in the first row of the html table.

    It retrieves date dbo_tblUser.html using Microsoft HTML Object Library and use FileSystemObject to save as a new file. You could also use FileSystemObject to manipulate it as a text file.

    Sub test()
    Dim doc1 As New HTMLDocument, doc2 As New HTMLDocument
    Dim ele As HTMLTable
    url = "file://E:\test\dbo_tblUser.html"
    Set doc1 = doc2.createDocumentFromUrl(url, "null")
    Do Until doc1.ReadyState = "complete"
    DoEvents
    Loop
    Set ele = doc1.all.tags("TABLE")(0)
    Dim row As HTMLTableRow
    Dim cell1 As HTMLTableCell, cell2 As HTMLTableCell
    Set row = ele.insertRow(1)
    Set cell1 = row.insertCell(0)
    Set cell2 = row.insertCell(1)
    cell1.innerText = "0"
    cell2.innerText = "TEST"
    Dim newHTML As String
    newHTML = doc1.head.innerHTML + doc1.body.innerHTML
    Dim fso As Object
    Set fso = CreateObject("Scripting.FileSystemObject")
    Dim oFile As Object
    Set oFile = fso.CreateTextFile("E:\test\newHtml.html")
    oFile.WriteLine newHTML
    oFile.Close
    Set fso = Nothing
    Set oFile = Nothing
    End Sub
