Custom error handling with the CVCError event.

Question

How can I use customized error handling?

Résponse

Most CVC ActiveX controls support the i>CVCErrorEvent which is fired when e.g. an Résponse/fr/produits/acquisition">acquisition timeout occurs. Custom error handling can be performed by handling this event.
The provided error code parameter specifies the error which is responsible for the event. According to this code your application can react on the error. In addition the error string contains a verbal description of the error code the continue parameter is provided.
The continue parameter is initialised to an appropriate value before the event is fired. When set to true the cause of the error is ignored and if possible the process will be continued (e.g. further images are going to be acquired after an acquisition timeout). Also a message box will be shown to inform the user of the error. This will also happen if you don't handle the CVCError event. When set to false the current process will be stopped and no message box will be displayed.
Thus if you want to realize custom error handling for e.g. acquisition timeouts you could set continue to false and show a custom message box to stop image acquisition and to present a customized message.
