使用C++Windowsh写一个700500的页面并且绘制一个蓝色边框蓝色填充的按钮并在鼠标按到按钮时绘制一个红色边框红色填充的图形

以下是使用C++的Windows.h库来创建一个700*500的页面，并绘制一个蓝色边框、蓝色填充的按钮。当鼠标按下按钮时，会绘制一个红色边框、红色填充的图形。

#include <Windows.h>

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

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nShowCmd)
{
    // 创建窗口
    HWND hwnd;
    WNDCLASSEX wc = { sizeof(WNDCLASSEX), CS_CLASSDC, WindowProc, 0L, 0L, GetModuleHandle(NULL), NULL, NULL, NULL, NULL, "MyWindowClass", NULL };
    RegisterClassEx(&wc);
    hwnd = CreateWindow(wc.lpszClassName, "My Window", WS_OVERLAPPEDWINDOW, 100, 100, 700, 500, NULL, NULL, wc.hInstance, NULL);
    
    // 显示窗口
    ShowWindow(hwnd, nShowCmd);
    UpdateWindow(hwnd);

    // 消息循环
    MSG msg;
    while (GetMessage(&msg, NULL, 0, 0) > 0)
    {
        TranslateMessage(&msg);
        DispatchMessage(&msg);
    }

    // 清理
    UnregisterClass(wc.lpszClassName, wc.hInstance);
    return 0;
}

LRESULT CALLBACK WindowProc(HWND hwnd, UINT uMsg, WPARAM wParam, LPARAM lParam)
{
    // 绘制设备
    HDC hdc;
    PAINTSTRUCT ps;

    // 用于存储按钮的位置和状态
    RECT buttonRect = { 100, 100, 200, 150 };
    bool buttonPressed = false;

    switch (uMsg)
    {
    case WM_PAINT:
        hdc = BeginPaint(hwnd, &ps);

        // 绘制蓝色边框和填充
        HPEN hPen = CreatePen(PS_SOLID, 1, RGB(0, 0, 255));
        HBRUSH hBrush = CreateSolidBrush(RGB(0, 0, 255));
        SelectObject(hdc, hPen);
        SelectObject(hdc, hBrush);
        Rectangle(hdc, buttonRect.left, buttonRect.top, buttonRect.right, buttonRect.bottom);

        // 如果按钮被按下，则绘制红色边框和填充
        if (buttonPressed)
        {
            HPEN hRedPen = CreatePen(PS_SOLID, 1, RGB(255, 0, 0));
            HBRUSH hRedBrush = CreateSolidBrush(RGB(255, 0, 0));
            SelectObject(hdc, hRedPen);
            SelectObject(hdc, hRedBrush);
            Rectangle(hdc, buttonRect.left, buttonRect.top, buttonRect.right, buttonRect.bottom);
            DeleteObject(hRedPen);
            DeleteObject(hRedBrush);
        }

        DeleteObject(hPen);
        DeleteObject(hBrush);
        EndPaint(hwnd, &ps);
        break;

    case WM_LBUTTONDOWN:
        // 检查鼠标是否按在按钮上
        if (LOWORD(lParam) >= buttonRect.left && LOWORD(lParam) <= buttonRect.right &&
            HIWORD(lParam) >= buttonRect.top && HIWORD(lParam) <= buttonRect.bottom)
        {
            buttonPressed = true;
            InvalidateRect(hwnd, &buttonRect, TRUE); // 使按钮区域无效，触发重绘
        }
        break;

    case WM_LBUTTONUP:
        // 检查鼠标是否释放在按钮上
        if (buttonPressed)
        {
            buttonPressed = false;
            InvalidateRect(hwnd, &buttonRect, TRUE); // 使按钮区域无效，触发重绘
        }
        break;

    case WM_DESTROY:
        PostQuitMessage(0);
        break;
    }

    return DefWindowProc(hwnd, uMsg, wParam, lParam);
}
