Can anyone help with providing an option to attach files such as MS
Word or Excel document to a database record and be able to view
without having to store the document as an OLE object? I want to be
able to link the darabase record to many related files.
Thanks,
Sure. I simply store the full path name of the file in a text field
(using a file dialog to choose your file). I have a table allowing
multiple file "attachments" per employee (displayed in a Listbox).
I then have some code to open the file (should work with any file
extension recognised by Windows and if the program accepts a file to
open in the command line when callling it). The code calls a function
that gets the program associated with the file extension.
eg. (This is a bit messy but should give you the idea)
Private Sub btnOpen_Click()
'get program associated with file extension (pass file and folder
seperately)
ProgPath = fFindEXE(Me![FileList].Column(1), Me![FileList].Column(2))
'strip null characters if any??
For i = 1 To Len(ProgPath)
c = Mid(ProgPath, i, 1)
If c <> Chr(0) Then
NewProgPath = NewProgPath & c
End If
Next
'strip spaces from start/end of string
If Len(NewProgPath) > 0 Then NewProgPath = Trim(NewProgPath)
'remove /n being added on Win95c computers??
If Mid(NewProgPath, Len(NewProgPath) - 1, 1) = "/" Then NewProgPath =
Left(NewProgPath, Len(NewProgPath) - 2)
FilePath = Me![FileList].Column(2) & Me![FileList].Column(1)
'construct as if writing a shortcut, adding quotes etc
FullPath = Chr(34) & NewProgPath & Chr(34) & Chr(32) & Chr(34) &
FilePath & Chr(34)
'open program/file
r = Shell(FullPath, vbNormalFocus)
End Sub
