This class defines an ATL exception.
Casts the current object to an HRESULT value.
Public Data Members
The variable of type HRESULT created by the object and used to store the error condition.
A CAtlException object represents an exception condition related to an ATL operation. The CAtlException class includes a public data member that stores the status code indicating the reason for the exception and a cast operator that allows you to treat the exception as if it were an HRESULT.
In general, you will call AtlThrow rather than creating a CAtlException object directly.
