Find a solution, will catch (CFileException e) into the catch (CFileException * e),


Does anyone know why this is?

Can you under the specific said, a bit not understand

CodePudding user response:

CFile delivery CFileException is new out
Also catch also corresponds to the Delete

 
Try 
{
//Do something to throw a file exception. 
} 
The catch (CFileException * theException) 
{
If (theException - & gt; M_cause==CFileException: : fileNotFound)
