C++ Create Simple Window

//The first box appears, but then it stops after that. Please help, and thanks in advanced!

Code:

---

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

const string title = "Diplomacy :: Version 0.01 :: Created by onlineone22";

int WINAPI WinMain(HINSTANCE hInstance,
                  HINSTANCE hPrevInstance,
                  LPSTR lpCmdLine,
                  int nCmdShow)
{
    int launch = MessageBox(NULL, "Would you like to launch Diplomacy?", title.c_str(), MB_YESNO);

    if(launch == IDYES)
    {
        CreateWindowEx
        (
            0,
            NULL,
            title.c_str(),
            WS_SYSMENU,
            CW_USEDEFAULT,
            CW_USEDEFAULT,
            445,
            445,
            HWND_DESKTOP,
            NULL,
            hInstance,
            NULL
        );
    }

    return 0;
}

Did you try to debug your code?
Anyway, it looks like you just return from the WinMain after creating (or not creating) the window...

You can do that by sfml graphics, its so simple:

Just follow this syntax:

RenderWindow windowname(Videomode(height,width), "Name to appear on the top")

But for that you need to have sfml libraries on your computer.

Do it like this :

Code:

Code:

---

#include<iostream>
#include<SFML/Graphics.hpp>

using namespace std;
using namespace sf;

int main()
{
    cout << "Would you like to launch diplomacy?" << endl;
    char YESNO = '/0';
    do
{
    RenderWindow window(VideoMode(445, 445), "Diplomacy :: version 0.01 :: Created by onlineone22);
    window.setFrameratelimit(60);
      window.clear();
      window.display();

}while (YESNO == IDYES)

return 0;
}

As this simple test program doesn't contain the required sfml #include statement, I doubt it will compile. Also the YESNO variable isn't changed within the loop and the while condition is an assignment rather than an equality test. :thumbd:

Oh sorry!

Now it will compile

CreateWindowEx just creates a window. To make it be alive and respond to user events, keyboard or mouse, you need to implement window procedure and spin up a message loop.
