Tenho esse código de uma janela de um projeto do codeblocks e gostaria de saber como esconder o cmd e deixar apenas a janela.

LRESULT CALLBACK WindowProcedure (HWND, UINT, WPARAM, LPARAM);

TCHAR szClassName[ ] = _T("CodeBlocksWindowsApp");

int WINAPI WinMain (HINSTANCE hThisInstance, HINSTANCE hPrevInstance, LPSTR lpszArgument, int nCmdShow){
    HWND hwnd;
    MSG messages;
    WNDCLASSEX wincl;

    wincl.hInstance = hThisInstance;
    wincl.lpszClassName = szClassName;
    wincl.lpfnWndProc = WindowProcedure;
    wincl.style = CS_DBLCLKS;
    wincl.cbSize = sizeof (WNDCLASSEX);

    wincl.hIcon = LoadIcon (NULL, IDI_APPLICATION);
    wincl.hIconSm = LoadIcon (NULL, IDI_APPLICATION);
    wincl.hCursor = LoadCursor (NULL, IDC_ARROW);
    wincl.lpszMenuName = NULL;
    wincl.cbClsExtra = 0;
    wincl.cbWndExtra = 0;
    wincl.hbrBackground = (HBRUSH) COLOR_BACKGROUND;

    if(!RegisterClassEx(&wincl))
        return 0;

    hwnd = CreateWindowEx(
        0,
        szClassName,
        _T("Code::Blocks Template Windows App"),
        WS_OVERLAPPEDWINDOW,

        HWND_DESKTOP,
        NULL,
        hThisInstance,
        NULL
    );

    ShowWindow (hwnd, nCmdShow);

    while(GetMessage(&messages, NULL, 0, 0)){
        TranslateMessage(&messages);
        DispatchMessage(&messages);
    }
    return messages.wParam;
}

LRESULT CALLBACK WindowProcedure (HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam){
    switch(message){
        case WM_DESTROY:
            PostQuitMessage (0);
            break;
        default:
            return DefWindowProc (hwnd, message, wParam, lParam);
    }
    return 0;
}
