Syntax

void CCFXRequest::ReThrowException(CCFXException* e)

Description

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.

Parameters

Example

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", "" ) ;
    }
