access thread: Checking a floppy disk


Message #1 by "Clive Astley" <clive.astley@k...> on Wed, 27 Feb 2002 18:40:33
How can I (a) check that a diskette is in the a:\ drive, (b) that the 

diskette is not write protected, and (c) that the floppy is empty (ie no 

files exist) please?

Hi Clive,

The Dir() function coupled with the GetAttr function should do the trick for

you.

Use DIR("A:\*.*") to verify the floppy and then

GetAttr to view the file attributes which will return a numeric code.

Here's

what I use



   

Function FileTest(sFile As String) As String            ' Find File / Test

attributes

Dim vResult As Variant, iAttrib

On Error GoTo FileError

  

  If Len(sFile & "") = 0 Then

    FileTest = "ERROR"

    Exit Function

  End If

  

  vResult = Dir(sFile)

  iAttrib = GetAttr(sFile)

  

  Select Case iAttrib

    Case Is = 0

      FileTest = "Ok"

    Case Is = 1

      FileTest = "Read-only"

    Case Is = 2

      FileTest = "Hidden"

    Case Is = 4

      FileTest = "System"

    Case Is = 16

      FileTest = "Directory or Folder"

    Case Is = 32

      FileTest = "Changed since last backup"

    Case Else

      FileTest = "ERROR - UNKNOWN FILE STATE"

  End Select

FileText_Exit:

  Exit Function



FileError:

  Beep

  Select Case Err.Number

  Case Is = 53                                  ' File not found

    FileTest = "File not found => " & sFile & " <="

    Resume FileText_Exit

  Case Is = 68                                  ' No Such Disk

    FileTest = "No such Drive ID => " & Left(sFile, 1) & ":"

    Resume FileText_Exit

  Case Is = 71                                  ' No Disk

    FileTest "ERROR - No disk in floppy drive => " & Left(sFile, 1) & ":"

    Resume FileText_Exit

  Case Else

    MsgBox Err.Number & " - " & Err.Description

    Resume FileText_Exit

  End Select

  

End Function
