Write a visual studio program in C++ using DirectX. The program has to show a full-screen green screen.

* Start with an empty project and have all the files in .cpp format. Use of .h files is not allowed.

* Include WinMain, WinProc, gameInitialize, gameRun and gameEnd in this way:

bool Game_Init(HWND hwnd);

void Game_Run(HWND hwnd);

void Game_End();

* An example of what I have for the main:

int WINAPI WinMain( HINSTANCE hInstance,

HINSTANCE hPrevInstance,

LPSTR lpCmdLine, int nCmdShow)

{

MSG msg;

MyRegisterClass(hInstance);

HWND hWnd;

hWnd = CreateWindow(

APPTITLE, APPTITLE, WS_OVERLAPPEDWINDOW,

CW_USEDEFAULT, CW_USEDEFAULT, 500, 400,

NULL, NULL, hInstance, NULL);

if (!hWnd)

return FALSE;

ShowWindow(hWnd, nCmdShow);

UpdateWindow(hWnd);

if (!Game_Init(hWnd))

return FALSE;

while (TRUE)

{

if (PeekMessage(&msg, NULL, 0, 0, PM_REMOVE))

{

if (msg.message == WM_DESTROY )

break;

TranslateMessage(&msg);

DispatchMessage(&msg);

}

Game_Run(hWnd);

}

Game_End();

return msg.wParam;

}

LRESULT CALLBACK WinProc (HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam)

{

switch (message)

{

case WM_DESTROY:

PostQuitMessage(0);

break;

}

//let the default window handler process the message

return DefWindowProc(hWnd, message, wParam, lParam);

}

* The above and below are NOT the entire program.

* Thank you in advance for your help.
