Scroll Picturebox with resizable form.

[sgrya1]

I'd just like to post this in case it helps anyone. Found this on microsoft's website and it does just what I wanted.

It adds horizontal and vertical scrollsbars to a picturebox (picture1) if the picturebox is larger than the form or when the form is resized to a size smaller than the picturebox. Reckon it might even be worthy of the codebank.

1. Start a new project in Visual Basic. Form1 is created by default.
2. Add a horizontal scroll bar control and a vertical scroll bar control to Form1. (The size doesn't matter because the program automatically sizes the scroll bars in the Form Resize event code.)
3. Add a picture box control to Form1.
4. Add the following code to the Form

Sub Form_Resize()
On Error Resume Next
   ' Position the scroll bars:
   HScroll1.Left = 0
   VScroll1.Top = 0
   If Picture1.Width > ScaleWidth Then
      HScroll1.Top = ScaleHeight - HScroll1.Height
   Else
      HScroll1.Top = ScaleHeight
   End If
   If Picture1.Height > HScroll1.Top Then
      VScroll1.Left = ScaleWidth - VScroll1.Width
      If Picture1.Width > VScroll1.Left Then
         HScroll1.Top = ScaleHeight - HScroll1.Height
      End If
   Else
      VScroll1.Left = ScaleWidth
   End If
   HScroll1.Width = ScaleWidth
   If HScroll1.Top > 0 Then VScroll1.Height = HScroll1.Top
   ' Set the scroll bar ranges
   HScroll1.Max = Picture1.Width - VScroll1.Left
   VScroll1.Max = Picture1.Height - HScroll1.Top
   HScroll1.SmallChange = Picture1.Width / 10
   HScroll1.LargeChange = Picture1.Width - HScroll1.Max
   VScroll1.SmallChange = Picture1.Height / 10
   VScroll1.LargeChange = Picture1.Height - VScroll1.Max
   HScroll1.ZOrder 0
   VScroll1.ZOrder 0
End Sub
Sub HScroll1_Change()
    Picture1.Left = -HScroll1.Value
End Sub
Sub VScroll1_Change()
    Picture1.Top = -VScroll1.Value
End Sub
Private Sub HScroll1_GotFocus()
Picture1.SetFocus
End Sub
Private Sub VScroll1_GotFocus()
Picture1.SetFocus
End Sub

You should post those kind of things into the CodeBank... anyways, i'm sure mod will move it for you

I'm a rookie and don't know my place. Do think it should be there though.

Any suggestions for adding wheelmouse scrolldown?

And if anyone has a chance to look over it and correct it, the slider size isn't quite right with respect to the amount it should scroll.
