Not satisfied with the solutions available on net. I tried a workaround which i want to share..
Reason :
When you set the Image roperty of a PictureBox which is having width or height grearter than 32767.This the limit of PictureBox image width.
Workaround:
Create your own PictureBox Class
Private Class MyPictureBox
Inherits System.Windows.Forms.PictureBox
Public Event WrongImage(ByVal Message As String)
Protected Overrides Sub OnSizeModeChanged(ByVal e As System.EventArgs)
If Me.Image.Width >= 32767 OrElse Me.Image.Height >= 32767 Then
Me.Image = Nothing
RaiseEvent WrongImage("Image is in incorrect format.Please verify manually.")
End If
End Sub
End Class
Use the above class as your PictureBox control on your form and handle the WrongImage event to take the necessary action.
Private Sub picSign_WrongImage(ByVal Message As String) Handles picSign.WrongImage
lblSign.Text = Message
End Sub
Note: The stacktrace of an exception indicates that the Exception is raised internally , not by the form or picturebox we code.
As i am overriding OnSizeModeChanged method , do set SizeMode property of the PictureBox on your form
