Visual Basic

Public Event DrawException( _
   ByVal Index As Long, _
   ByVal Message As String, _
   ByRef Handled As Boolean _
)

Parameters

Index: The index of the image in the Images collection which generated the error
Message: The error message
Handled: Set to true if your code handles the error in a way which allows DicomObjects to re-attempt the drawing.

Remarks

This may be used to trap and handle errors which occur during drawing on the surface of the DicomViewer.

If you have "handled" this error and wish DicomObjects to try again, set the Handled parameter (by ref) to true, but beware infinite loops.
