CComBSTR::CComBSTR

CComBSTR( );

CComBSTR( int nSize );

CComBSTR( int nSize, LPCOLESTR sz );

CComBSTR( int nSize, LPCSTR sz );

CComBSTR( LPCOLESTR pSrc );

CComBSTR( LPCSTR pSrc );

CComBSTR( const CComBSTR& src );

Parameters

nSize

[in] The number of characters to copy from sz.

sz

[in] A string to copy. The Unicode version specifies an LPCOLESTR; the ANSI version specifies an LPCSTR. Only nSize characters will be copied. The default value is NULL.

pSrc

[in] A string to copy. The Unicode version specifies an LPCOLESTR; the ANSI version specifies an LPCSTR.

src

[in] A CComBSTR object.

Remarks

The default constructor sets the m_str member to NULL. The copy constructor sets m_str to a copy of the BSTR member of src.

The other four constructors set m_str to a copy of the specified string; however, if you pass a value for nSize, then only nSize characters will be copied, followed by a terminating null character.

The destructor frees the string pointed to by m_str.
