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.

For a list of Win32 error codes, see Error Codes. For a list of Internet-specific error messages, see . Both topics are in the Windows SDK.
