How to remove scrollbars in console windows C++

问题:

I have been checking out some Rogue like games (Larn, Rogue, etc) that are written in C and C++, and I have noticed that they do not have the scrollbars to the right of the console window.

How can I accomplish this same feature?

These guys show how to do it:

#include <windows.h>
#include <iostream>
using namespace std;

int main()
{
    HANDLE hOut;
    CONSOLE_SCREEN_BUFFER_INFO SBInfo;
    COORD NewSBSize;
    int Status;

    hOut = GetStdHandle(STD_OUTPUT_HANDLE);

    GetConsoleScreenBufferInfo(hOut, &SBInfo);
    NewSBSize.X = SBInfo.dwSize.X - 2;
    NewSBSize.Y = SBInfo.dwSize.Y;

    Status = SetConsoleScreenBufferSize(hOut, NewSBSize);
    if (Status == 0)
    {
        Status = GetLastError();
        cout << "SetConsoleScreenBufferSize() failed! Reason : " << Status << endl;
        exit(Status);
    }

    GetConsoleScreenBufferInfo(hOut, &SBInfo);

    cout << "Screen Buffer Size : ";
    cout << SBInfo.dwSize.X << " x ";
    cout << SBInfo.dwSize.Y << endl;

    return 0;
}

You need to make the console screen buffer the same size as the console window. Get the window size with GetConsoleScreenBufferInfo, srWindow member. Set the buffer size with SetConsoleScreenBufferSize().
