Can you post some sample code?
(specifically where you control the name/location of the tiff file)

 

[J]

a user control:
Private Sub imageControl_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load
Try
tmpFileName = "c:\logo.jpg"
view = Image.FromFile(tmpFileName)
Catch ex As Exception
view = Nothing
End Try
End Sub

Private Sub imageControl_Paint(ByVal sender As Object, ByVal e As
System.Windows.Forms.PaintEventArgs) Handles MyBase.Paint
e.Graphics.Transform = transform
' Draw Image using the DrawImage method
If (Not (view Is Nothing)) Then
e.Graphics.DrawImage(view, New Rectangle(Me.AutoScrollPosition.X,
Me.AutoScrollPosition.Y, (view.Width * curZoom), (view.Height * curZoom)))
End If
End Sub

on the main program:
Private Sub showImage()
Try
ImageControl1.view = Image.FromFile(Current_Image_File_Path)
Dim img As Image = Image.FromFile(Current_Image_File_Path)
img.Dispose()
End Try

' Repaint the form, which forces the Paint
' event hanlder
Me.ImageControl1.Invalidate()
End Sub
