IWiaErrorHandler interface (wia_lh.h)

  • Artikel

The IWiaErrorHandler interface provides the GetStatusDescription and ReportStatus methods, which enable minidrivers to give users information about status or errors during a data transfer and possibly give an opportunity to recover from errors.

Inheritance

The IWiaErrorHandler interface inherits from the IUnknown interface.

Methods

The IWiaErrorHandler interface has these methods.

 
IWiaErrorHandler::GetStatusDescription

The system UI calls the GetStatusDescription method to provide the user with extra information about an error, if the user requests this information. This method is implemented by a driver's UI extension.
IWiaErrorHandler::ReportStatus

The ReportStatus method displays information about an error or status during a transfer. In some cases this method allows the user to recover from an error.
