BSTR to CString

[Laurent Bernard]

When i try to read a BSTR in a COleVariant with

CString Cs;
Cs.Format("%s", Variant.bstrVal);

my Cs contains just the first character of the string. Could you explain me why and what is the good methode to do this !

CString Cs = Variant.bstVal;

1. use _bstr_t.
It has a char* operator.
So, u can use it like this :
_bstr_t my_bstr;
CString s1 = (char*)my_bstr;

Or
2. You can try this:
Variant.vt = VT_BSTR;
CString s2 = V_BSTRT(&Variant);
