Try google.com next time. Its power are godlike.

C++ is a Computer Programming language that is compatible with a ton of things... Refer to the google master for more information.

Best way would be found right here at http://www.gamedev.net/reference/articles/article1076.asp.

As an aside, C++ is not a Windows language. It can be used on any platform that possess a C++ compiler, which means it works on much more than Windows. :)

It seems that that was what I was trying....


.... 'that'..... You mean google? Its tough stuff, I understand, but when you can create some good searching analogies, you'll become a master at the googling.

Its in you, you've just got to dig deep inside yourself. ;]

I'm not sure what kind of window you have right now, but if you just need some text in a nice looking window on the screen, use this:
MessageBox("Text");

Well, what I was doing was functions that create a window for you! :) Problem is, it says:

C:/CPP/Main.cpp: In function `int main()':
C:/CPP/Main.cpp:8: error: `CreateWND' undeclared (first use this function)
C:/CPP/Main.cpp:8: error: (Each undeclared identifier is reported only once for
each function it appears in.)


Here's the code for Main.cpp:
#include <iostream>
#include "Functions.h"
#include "Functions.cpp"
using namespace std;

int WinMain()
{
CreateWND("TEST", 500, 500);
}





Functions.h:
int CreateWND(string Title, int Width, int Height)




And Functions.cpp:
#include <iostream>
#include <string>
using namespace std;

int CreateWND(string Title, int Width, int Height)
{
/* Declare Windows procedure */
LRESULT CALLBACK WindowProcedure (HWND, UINT, WPARAM, LPARAM);

/* Make the class name into a global variable */
char szClassName[ ] = "WindowsApp";

int WINAPI WinMain (HINSTANCE hThisInstance,
HINSTANCE hPrevInstance,
LPSTR lpszArgument,
int nFunsterStil)

{
HWND hwnd; /* This is the handle for our window */
MSG messages; /* Here messages to the application are saved */
WNDCLASSEX wincl; /* Data structure for the windowclass */

/* The Window structure */
wincl.hInstance = hThisInstance;
wincl.lpszClassName = szClassName;
wincl.lpfnWndProc = WindowProcedure; /* This function is called by windows */
wincl.style = CS_DBLCLKS; /* Catch double-clicks */
wincl.cbSize = sizeof (WNDCLASSEX);

/* Use default icon and mouse-pointer */
wincl.hIcon = LoadIcon (NULL, IDI_APPLICATION);
wincl.hIconSm = LoadIcon (NULL, IDI_APPLICATION);
wincl.hCursor = LoadCursor (NULL, IDC_ARROW);
wincl.lpszMenuName = NULL; /* No menu */
wincl.cbClsExtra = 0; /* No extra bytes after the window class */
wincl.cbWndExtra = 0; /* structure or the window instance */
/* Use Windows's default color as the background of the window */
wincl.hbrBackground = (HBRUSH) COLOR_BACKGROUND;

/* Register the window class, and if it fails quit the program */
if (!RegisterClassEx (&wincl))
return 0;

/* The class is registered, let's create the program*/
hwnd = CreateWindowEx (
0, /* Extended possibilites for variation */
szClassName, /* Classname */
Title, /* Title Text */
WS_OVERLAPPEDWINDOW, /* default window */
CW_USEDEFAULT, /* Windows decides the position */
CW_USEDEFAULT, /* where the window ends up on the screen */
Width, /* The programs width */
Height, /* and height in pixels */
HWND_DESKTOP, /* The window is a child-window to desktop */
NULL, /* No menu */
hThisInstance, /* Program Instance handler */
NULL /* No Window Creation data */
);

/* Make the window visible on the screen */
ShowWindow (hwnd, nFunsterStil);

/* Run the message loop. It will run until GetMessage() returns 0 */
while (GetMessage (&messages, NULL, 0, 0))
{
/* Translate virtual-key messages into character messages */
TranslateMessage(&messages);
/* Send message to WindowProcedure */
DispatchMessage(&messages);
}

/* The program return-value is 0 - The value that PostQuitMessage() gave */
return messages.wParam;
}


/* This function is called by the Windows function DispatchMessage() */

LRESULT CALLBACK WindowProcedure (HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam)
{
switch (message) /* handle the messages */
{
case WM_DESTROY:
PostQuitMessage (0); /* send a WM_QUIT to the message queue */
break;
default: /* for messages that we don't deal with */
return DefWindowProc (hwnd, message, wParam, lParam);
}

return 0;
}

}
