I have created a file upload dialog that simply puts the path to the file in a text box, however when I try to save the string to the DB there is hidden characters at the end of the path  to be exact. The Access DB does not like the  character. How do I avoid getting these into my string, simpler yet How can I find the start of the .   If I can trim everything after the file name (c:\images\joe.jpg) that would be great but I can not seem to just trim after the .jpg . Help

Those are probably CarriageReturn/LineFeed characters.

You didn't say what version of Access you were using, but in Access 2000+ you can use the Replace function:

Replace(YourString, vbCrLf, "")

They could be these as well:

vbCR
vbLF
vbTab

or a few others ... try each and see what returns the best result.

try this function to remove characters


Public Function StripHighBitChars(sMemoText As String) As String

    Dim sReturn As String
    Dim x
   
    sReturn = ""
    For x = 1 To Len(sMemoText)
   
        ' The space character is 32.  Tilde (~) is the last low-bit printable character at 126.
        ' Chr(127) is DEL (non-printable) on a lot of systems now, so I did not include it.
        If ((Asc(Mid(sMemoText, x, 1)) > 31) And (Asc(Mid(sMemoText, x, 1)) < 127)) Then _
            sReturn = sReturn & Mid(sMemoText, x, 1)
    Next
   
    StripHighBitChars = sReturn

End Function



Simply pass in your string
e.g.

    Dim sNewStr As String
   
    sNewStr = "c:\images\joe.jpg"
    MsgBox "Before : " & sNewStr
    sNewStr = StripHighBitChars(sNewStr)
    MsgBox "After : " & sNewStr
