An abstract class that represents an exception thrown during processing of a ColdFusion Extension (CFX) procedure.

Exceptions of this type can be thrown by CCFXRequest class, CCFXQuery class, and CCFXStringSet class. Your ColdFusion Extension code must be written to handle exceptions of this type. For more information, see CCFXRequest::ThrowException and CCFXRequest::ReThrowException.

Class methods

CCFXException::GetError

Description

Provides basic user output for exceptions that occur during processing.

CCFXException::GetDiagnostics

Description

Provides detailed user output for exception that occur during processing.

Example

This code block shows how GetError and GetDiagnostics work with ThrowException and ReThrowException.

// Write output back to the user here...
    pRequest->Write( "Hello from CFX_FOO2!" ) ;
    pRequest->ThrowException("User Error", "You goof'd...");
    
    // Output optional debug info
    if ( pRequest->Debug() )
    {
                        pRequest->WriteDebug( "Debug info..." ) ;
    }
    
    // Catch ColdFusion exceptions & re-raise them
    catch( CCFXException* e )
    {
                        // This is how you would pull the error information
                        LPCTSTR strError = e->GetError();
                        LPCTSTR strDiagnostic = e->GetDiagnostics();
    
                        pRequest->ReThrowException( e ) ;
    }
    
    // Catch ALL other exceptions and throw them as
    // ColdFusion exceptions (DO NOT REMOVE! --
    // this prevents the server from crashing in
    // case of an unexpected exception)
    catch( ... )
    {
                        pRequest->ThrowException(
                        "Error occurred in tag CFX_FOO2",
                        "Unexpected error occurred while processing tag." ) ;
}
