WARNING: ANY USE BY YOU OF THE CODE PROVIDED IN THIS ARTICLE IS AT YOUR OWN
RISK. Microsoft provides this code "as is" without warranty of any kind, either
express or implied, including but not limited to the implied warranties of

The following sample code takes a text file from the local hard drive on the
client and appends it to the current DHTML page:

1. Start a new Visual Basic project and select DHTML Application.

2. Open DHTMLPage1 under Designers (Project Explorer).

3. Add a TextField to the page, and set its value property to nothing.

4. Add a Button to the page, and set its value property to "Add File."

5. In the Properties window, select DispIHTMLBodyElement, and set its Id
  property to "test."

6. For the Button1_OnClick event, add the following code:

        Private Function Button1_onclick() As Boolean

        Dim f As Integer            ' File Handle
        Dim txt As String           ' Holds text of file for
                                    ' processing
        Dim strLoc As Long          ' Holds current location for
                                    ' INSTR

        f = FreeFile

        If Len(Dir$(TextField1.Value)) > 0 Then
           Open TextField1.Value For Input As #f
               txt = Input$(LOF(f), f)
           Close #f
          else
           test.innerHTML = test.innerHTML & "<BR><BR>File Not Found."
           Exit Function
        End If

        ' Convert CR/LF to HTML line break (<BR>) tags.

        strLoc = InStr(txt, vbCrLf)

        Do While strLoc <> 0
           txt = Mid$(txt, 1, (strLoc - 1)) & "<BR>" _
              & Mid$(txt, strLoc + 2)
           strLoc = InStr(strLoc + 1, txt, vbCrLf)
        Loop

        ' Add Contents of Text file to end of DHTML page.

        test.innerHTML = test.innerHTML & "<BR><BR>" & txt

        End Function


1. Run the code and type the name of a text file in the text box.
