Re: CComBSTR vs string
I have a function that returns a std::string type.
string getCallFunction(CComBSTR& movie)
string smovie( W2A(movie) );
string s = "<invoke name=\"flashLoadClip\"
returntype=\"xml\"><arguments>"; s += "<string>";
s += smovie;
s += "</string>";
s += "</arguments></invoke>";
In this sample you don't need std::string at all. CComBSTR
class already has `operator +='. Moreover, converting BSTR
(wide character string) to std::string can result in data
loss if BSTR contains characters which don't exist in
later on i set a CComBSTR ;
string s = getCallFunction( m_movie );
CComBSTR b = s.c_str();
Anyways, while debuging this, the std string contains all
the characters but CComBSTR is cliped and i lose
characters. what's going on ?
First of all, check in debugger settings that "Show Unicode
strings" (or similar wording) is enabled.
Second, as I mentioned before consider to eliminate
std::string at all.
