HRESULT ATL: : CImage: : Save (LPCTSTR, const GUID & amp;) Throw () const
Where is a const char [17] "assigned to a cost * object?

: yes, I want to invoke ATL CImage: : Save the first parameter is the cost, however, I want to pass a string to do

Can you put the string (string or char []) into cost? Then how to translate?

No, not the default conversion operations,
The input stream is cost? That you put the stream of data read into a string, and then handed in, but also depends on how you are actually going to specific application,

Retrieves the Save (
Cost * pStream, 
REFGUID guidFileType

Retrieves the Save (
LPCTSTR pszFileName, 
REFGUID guidFileType=GUID_NULL 
) const throw ();

Can mImag. Save ((LPCTSTR) cstrings (sName));
