Constructor & Destructor Documentation

WCL::ComException::ComException	(	HRESULT	result,
		const tchar *	operation
	)

Construction from a non-IErrorInfo supported error.

Constructor for use with non-IErrorInfo errors.

The pszOperation parameter is used as the prefix for the message and the error code is appended.

WCL::ComException::ComException	(	HRESULT	result,
		const tstring &	operation
	)

Construction from a non-IErrorInfo supported error.

template<typename T >

WCL::ComException::ComException	(	HRESULT	result,
		IFacePtr< T > &	object,
		const tchar *	operation
	)		`[inline]`

Construction from an IErrorInfo supported error.

WCL::ComException::~ComException ( ) throw () [virtual]

Destructor.

WCL::ComException::ComException ( HRESULT result ) [protected]

Construction from an error code.

bool WCL::ComException::extractErrorInfo	(	IUnknown *	object,
		const IID &	iid,
		tstring &	source,
		tstring &	description
	)		`[static, protected]`

Extract the ErrorInfo details from the COM object, if present.

void WCL::ComException::formatError	(	HRESULT	result,
		IUnknown *	object,
		const IID &	iid,
		const tchar *	operation
	)		`[private]`

Format the error using the IErrorInfo details.
