将LPCTSTR转换为std::string
LPCTSTR folder_path;
char str[1024];
wsprintfA(str, "%S ",folder_path);
string str_(str);
去掉string的空格：
#include <iostream>
#include <string>
#include <boost/algorithm/string.hpp>
using namespace std;
using namespace boost;
int main() {
string s = " hello boost!! ";
trim(s);
cout << s << endl;
}
string与wstring之间有转换：
#include <string>
#include <algorithm>
// Prototype for conversion functions
std::wstring StringToWString(const std::string& s);
std::string WStringToString(const std::wstring& s);
std::wstring StringToWString(const std::string& s)
{
std::wstring temp(s.length(),L' ');
std::copy(s.begin(), s.end(), temp.begin());
return temp;
}
std::string WStringToString(const std::wstring& s)
{
std::string temp(s.length(), ' ');
std::copy(s.begin(), s.end(), temp.begin());
return temp;
}
using namespace std;
int main()
{
string s1 = "Hello";
wstring s2 = StringToWString(s1);
s1 = WStringToString(s2);
return 0;
}
