CCFXRequest::ReThrowException

void CCFXRequest::ReThrowException(CCFXException* e)

Re-throws an exception that has been caught within an extension procedure. This function is used to avoid having C++ exceptions that are thrown by DLL extension code propagate back into ColdFusion. Catch ALL C++ exceptions that occur in extension code, and either re-throw them (if they are of the CCFXException class) or create and throw a new exception pointer using CCFXRequest::ThrowException.

The following code demonstrates how to handle exceptions in ColdFusion Extension DLL procedures:

try
{
               ...Code that could throw an exception...
}
catch( CCFXException* e )
{
               ...Do appropriate resource cleanup here...
               // Re-throw the exception
               pRequest->ReThrowException( e ) ;
}
catch( ... )
{
               // Something nasty happened
 
               pRequest->ThrowException(
               "Unexpected error occurred in CFX tag", "" ) ;
}
