I have some code to read file,but it is used std::string, i need to use _bstr_t the code follow can works fine. how to change the type?
std::ifstream inFile("QdatPassWordconfig.config");
std::string sPassWord; //(here, i need to use _bstr_t)
std::string sTemp;
if (inFile.is_open())
{
if(std::getline(inFile,sTemp))
{
cout<<sTemp<<endl;
sPassWord=sTemp;
}
}
If you read the _bstr_t
documentation , you will see that its assignment operator takes a normal const char *
.
So it's probably just to assign to it:
_bstr_t sPassword;
// ...
sPassword = sTemp.c_str();
If you have trouble using normal narrow-character strings, you should convert all your code relating to this to use wide-character string, ie the classes with the w
prefix:
std::wifstream inFile("QdatPassWordconfig.config");
_bstr_t sPassword;
std::wstring sTemp;
if (inFile.is_open())
{
if(std::getline(inFile, sTemp))
{
std::wcout << sTemp << endl;
sPassword = sTemp.c_str();
}
}
