I want to open the TNSNAMES.ORA file for input and write its contents to a table.  I can do this if I supply full path (e.g. C:\Oracle92\network\ADMIN\tnsnames.ora) as "filename".  Since I don't always know the exact path, how would I construct the open statement (or the variable "filename") so that it would open the file wherever it is on the PC?

you could have a file selector box (Common Dialog) and have the user manually select the file.  Then use that filename from the file selector as your TNSNAMES.ORA file.

Or are you looking for the program to search the harddrive and look for the file?

Thanks for the quick response.  I am looking for the program to search the harddrive and look for the file.  Users would be totally lost as to where to even begin looking.

you can do a recursive file search by extension.  The code is provided at the link.  You can alter the code to search for the entire filename.  

How are you going to handle multiple filenames on a single disk drive?

Thanks, I am using MSAccess.
Code at the link looks like more than I need but maybe not!  
>How are you going to handle multiple filenames on a single disk drive?
Plan is to err out if more than one found.

the second link is probably the best link for you.  VB 6 is basically the same as Access VBA.

You can use the built-in FileSearch Object:

Sub FindFile()
    Dim i As Integer
   
    With Application.FileSearch
        .NewSearch
        .LookIn = "C:\"
        .SearchSubFolders = True
        .Filename = "TNSNAMES.ORA"
        .MatchTextExactly = True
            If .Execute() > 0 Then
            MsgBox "There were " & .FoundFiles.Count & _
                " file(s) found."
            For i = 1 To .FoundFiles.Count
                MsgBox .FoundFiles(i)
            Next i
        Else
            MsgBox "There were no files found."
        End If
    End With
End Sub

Thanks to everyone who responded.  The last answer from "GrahamSkan" is the one I needed.  I believe I will be able to complete what I started with that.

Please award points to Graham.
