1st step for Chinese Chess Program- Standard WinMain

#include "windows.h"


LRESULT CALLBACK WindowProc(HWND hWnd, UINT uMsg, WPARAM wParam, LPARAM lParam);

//Stand WinMain
int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow)
{
    //1. design WindowClass
    WNDCLASSEX wndClass;
    
    LPCTSTR szAppName = L"OFWIN";
    wndClass.cbSize = sizeof(WNDCLASSEX);
    wndClass.style = CS_HREDRAW | CS_VREDRAW;
    wndClass.lpfnWndProc = WindowProc;
    wndClass.cbClsExtra = 0;
    wndClass.cbWndExtra = 0;
    wndClass.hInstance = hInstance;
    wndClass.hIcon = LoadIcon(0, IDI_APPLICATION);
    wndClass.hCursor = LoadCursor(0, IDC_ARROW);
    wndClass.hbrBackground = static_cast<HBRUSH>(GetStockObject(GRAY_BRUSH));
    wndClass.lpszMenuName = 0;
    wndClass.lpszClassName = szAppName;
    wndClass.hIconSm = 0;
    
    
    //2. register
    RegisterClassEx(&wndClass);
    
    //3. create Window
    HWND hWnd = CreateWindow(
        szAppName,
        L"A standard WinMain Frame",
        WS_OVERLAPPEDWINDOW,
        CW_USEDEFAULT,
        CW_USEDEFAULT,
        CW_USEDEFAULT,
        CW_USEDEFAULT,
        0,
        0,
        hInstance,
        0    
        );
    
    //4. show Window
    ShowWindow(hWnd, nCmdShow);
    UpdateWindow(hWnd);
    
    //5. message routine
    MSG msg;
    while (GetMessage(&msg, 0, 0, 0))
    {
        TranslateMessage(&msg);
        DispatchMessage(&msg);
    }

    return static_cast<int>(msg.wParam);
}


LRESULT CALLBACK WindowProc(HWND hWnd, UINT uMsg, WPARAM wParam, LPARAM lParam)
{
    switch (uMsg)
    {
        //case WM_PAINT:
            //break;
        case WM_DESTROY:
            PostQuitMessage(0);
            break;
        default:
            return DefWindowProc(hWnd, uMsg, wParam, lParam);
    }
    
    return 0;
}

And the 2nd step is drawing out the whole Layout of Chinese chess.
