Does VS not like copypasta?
I found a port scanner online that I wanted to plug into the compiler to tinker with
Code:
#include <cstdlib>
#include <iostream>
#include <fstream>
#include <string>
#include <winsock.h>
#include <algorithm>
using namespace std;
// declare globals
SOCKET sock;
ofstream outfile;
//Connecttohost connects to a remote host
bool ConnectToHost(int PortNo, char* IPAddress) {
//start up winsock
WSADATA wsadata;
int error = WSAStartup(0×0202, &wsadata);
//error did something happen
if (error) {
return false;
}
// check if we get the right winsock version
if (wsadata.wVersion != 0×0202) {
if (wsadata.wVersion != 0×0202) {
WSACleanup();
return false;
}
SOCKADDR_IN target;
target.sin_family = AF_INET;
target.sin_port = htons (PortNo);
target.sin_addr.s_addr = inet_addr (IPAddress);
sock = socket (AF_INET, SOCK_STREAM, IPPROTO_TCP); // create socket
if (sock == INVALID_SOCKET)
{
return false; // could not create the socket
}
// try connecting
if (connect(sock, (SOCKADDR *)&target, sizeof(target)) == SOCKET_ERROR)
{
cout << "false" << endl;
outfile << "false" << endl;
return false; //couldn’t connect
}
else {
cout << "true" << endl;
outfile << "true" << endl;
return true; // success
}
}
void CloseConnection () {
if (sock)
closesocket(sock);
WSACleanup();
}
char *convertStringToChar(const string &str)
{
char *retPtr(new char[str.length() + 1]);
copy(str.begin(), str.end(), retPtr);
retPtr[str.length()] = ”;
return retPtr;
}
int main()
{
string line;
int myport1;
int myport2;
int i;
cout << "\n\n";
cout << "Enter the starting PORT You wish to attempt a connection on, example: \t 21 \n" << endl;
cin >> myport1;
cout << "Enter the Ending PORT You wish to attempt a connection on, example: \t 25 \n" << endl;
cin >> myport2;
outfile.open("outfile.txt");
ifstream myfile("input.txt");
if (myfile.is_open())
{
while (!myfile.eof())
{
getline(myfile, line);
for (i = myport1; i <= myport2; i++)
{
ConnectToHost(i, convertStringToChar(line));
cout << i << " \t " << line << endl;
outfile << i << " \t" << line << endl;
}
}
myfile.close();
outfile.close();
}
else cout << "Unable to open file input.txt\n\n";
system("PAUSE");
return EXIT_SUCCESS;
}
here are the errors I got

And the first time I compiled it, it thought for some reason that words inside quotes didn't count as strings. Oddly enough, it recognised them when I deleted and reentered the quotes. Is the code wrong or does VS just not like it when you copy and paste? If someone can give me a simpler port scan, I'd appreciate it. That's all I want.
