BSTR stra;
_bstr_t strb;
strb=stra;
CString strc=(LPCTSTR)strb;

[bager]

CString strTemp1 = "Test1";
CString strTemp2 = "Test2";
BSTR bstrTemp = NULL;

bstrTemp=strTemp1 .AllocSysString();

strTemp2 = bstrTemp;
SysFreeString(bstrTemp);

///////////////CString => BSTR//////////////////
BSTR pe;
CString e = _T("Hello");
pe = e.AllocSysString();

///////////////BSTR => CString//////////////////
CString str(pe);
