es complicado decir como funcionan totalmete probablemente te ayude este pedazo de mi aplicacion:
---------------------------------------------------------------------------------
NECESITAS
1 image
2 picture
2 timer
1 VScrollBar
1 HScrollBar
1 shape
----------------------------------------------------------------------------------
Public Sub Form_Resize()
On Error Resume Next
If Me.Width < 3000 Then
Me.Width = 3000
End If
If Me.Height < 2000 Then
Me.Height = 2000
End If
Scroll1.Left = Me.ScaleWidth - Scroll1.Width
Scroll1.Height = Me.ScaleHeight - 255
Scroll2.Top = Me.ScaleHeight - Scroll2.Height
Scroll2.Width = Me.ScaleWidth - 255
Picture2.Top = Me.ScaleHeight - Picture2.Height
Picture2.Left = Me.ScaleWidth - Picture2.Width
If Picture1.Height > Me.ScaleHeight Then
Scroll1.Visible = True
Picture2.Visible = True
Else
Scroll1.Visible = False
Picture1.Top = 0
End If
If Picture1.Width > Me.ScaleWidth Then
Scroll2.Visible = True
Picture2.Visible = True
Else
Scroll2.Visible = False
Picture1.Left = 0
End If
If Scroll1.Visible = False Then
If Scroll2.Visible = False Then
Picture2.Visible = False
End If
End If
If Scroll1.Visible = True Then
If Scroll2.Visible = False Then
Picture2.Visible = False
Scroll1.Height = Me.ScaleHeight
End If
Else
If Scroll2.Visible = True Then
If Scroll1.Visible = False Then
Picture2.Visible = False
Scroll2.Width = Me.ScaleWidth
End If
End If
End If
Scroll1.Max = (Picture1.Height - Me.ScaleHeight + 300) / 150
Scroll2.Max = (Picture1.Width - Me.ScaleWidth + 300) / 150
End Sub
Si los puedes usar en un frame, pero seria algo complicado
