how can i make a button open the next picture file

hey everyone again
i usually get good results coming here and asking questions even though u r probably all sick of me
anyway
i am making just a simple picture veiwer and i want to be able to veiw the next picture in the directory where the last picture came from and also how can i put a scroll bar on a picture box so i can see the rest of the image if its too big?
thanx in advance:-)

I don't know about the scrollbar, but for loading the next picture in the directory, you can use the Dir function. First:

'this will return the first JPG file it finds in the dir.
Dim FName As String
FName = Dir(Directory & "\*.jpg", vbNormal)

Now everytime onwards you use

FName = Dir     'variable does not have to be FName again

it will return the next filename as specified by the first Dir (*.jpg). It will do this until you specify a new file type/directory or when it finds no more files, in which case it will return an empty string.

Thanx for this help but i cant work it out where exaclty do i put all thi s code lol?
thanx

Now this assumes you have a Open button, and everytime you click it, it will load the next picture in the specified directory with the specified extension.

Option Explicit
Dim First As Boolean

Private Sub cmdOpen_Click()
   Dim FName As String

   If Right(txtDir, 1) <> "\" Then
      txtDir = txtDir & "\"
   End If

   If First = True Then
      FName = Dir(txtDir & txtExt, vbNormal)
      First = False
   Else
      FName = Dir
   End If

   If Dir = "" Then
      First = True
      Exit Sub
   End If

   Picture1.Picture = LoadPicture(txtDir & FName)

End Sub

Private Sub Form_Load()
    First = True
End Sub

Hope this helps,
Sunny
