Hyperlink question

[RayMilhon]

I have a database I'm building the Backend will be SQL Server 2012 the front end will be MS Access 2010. One of the fields in SQL Server will be a varchar(100) field which will contain the path to a file Such as \\Server1\Contracts\VMMS1234.pdf

What I'm looking to do is when the user clicks on that field the pdf file will open. If the field is empty the user will be prompted to locate the correct file to place in that field. I just have no clue how to proceed. Anybody know where I can look up this information or point me in the direction of accomplishing this?

Thanks in advance

I have a User defined function and some vba that I've used in my database. I'll track it down and post it here soon

See if this helps:

  If Me.txtAttachment = "None" Or Len(Me.txtAttachment & vbNullString) = 0 Then

    strFilter = ""  'ahtAddFilterItem(strFilter, "Excel Files (*.XLS)", "*.XLS")
    strInputFileName = ahtCommonFileOpenSave(InitialDir:="Path for default here", _
                                             Filter:=strFilter, OpenFile:=True, _
                                             DialogTitle:="Please select an input file...", _
                                             Flags:=ahtOFN_HIDEREADONLY)

    Me.txtAttachment = strInputFileName
  Else
    'Application.FollowHyperlink Me.txtAttachment
    Dim objshell              As Object
    Set objshell = CreateObject("Shell.application")
    objshell.Shellexecute Me.txtAttachment, , , , 1
  End If

Well, looks like pbaldy beat me to it...but here it is anyway.

Private Sub txtAttachmentPath_DblClick(Cancel As Integer)
 
Dim strFile As String
strFile = Me.txtAttachment
 
If Len(Dir(strFile, vbDirectory)) = 0 Then
    Dim dlgOpen As FileDialog
    Set dlgOpen = Application.FileDialog(msoFileDialogOpen)
    With dlgOpen
    .AllowMultiSelect = False
    .InitialFileName = "C:\" 'Initial Path when explorer is opened
    .Show
        If .SelectedItems.Count = 0 Then
            MsgBox "No file selected"              'No folder selected
        Else
            Me.txtAttachment = .SelectedItems(1)
        End If
    End With
Else
    X = fHandleFile(strFile, WIN_NORMAL)
End If
End Sub

You will also need to create a user defined function: Alt+F11 > Insert Module then paste the below code into module:

This might be more convoluted that pbaldy's but its worked for me.
