CInternetException::CInternetException
This member function is called when a CInternetException object is created.
CInternetException(DWORD dwError);
Parameters
dwError
The error that caused the exception.
Remarks
To throw a CInternetException, call the MFC global function AfxThrowInternetException.
CInternetException::m_dwContext
The context value associated with the related Internet operation.
DWORD_PTR m_dwContext;
Remarks
The context identifier is originally specified in CInternetSession and passed by MFC to CInternetConnection- and CInternetFile-derived classes. You can override this default and assign any dwContext parameter a value of your choosing. dwContext is associated with any operation of the given object. dwContext identifies the operation's status information returned by CInternetSession::OnStatusCallback.
CInternetException::m_dwError
The error that caused the exception.
DWORD m_dwError;
Remarks
This error value may be a system error code, found in WINERROR.H, or an error value from WININET.H.
