问题

我正在制作一个程序，可以发送我想要的自定义通知。我有一个显示在屏幕上的窗口，但是图像没有加载。

我已经尝试使用Chat GPT来检查我的代码，但由于其知识限制是在2021年9月，它不知道API的新更新，无法给我正确的回答。

以下是您的代码部分：

#include <Windows.h>
#include <Shellapi.h>

// 常量
#define WM_CLOSENOTIFICATION (WM_USER + 1)
#define BUTTON_OPENURL_ID 100
#define BUTTON_CLOSE_ID 101
#define IDB_NOTIFICATION_BITMAP 108 // 用您的位图资源ID替换

// 全局变量
HWND hMainWindow;
HWND hNotificationWindow;
HBITMAP hBitmap;

// 创建和显示通知窗口的函数
void ShowNotification()
{
    // 获取屏幕尺寸
    int screenWidth = GetSystemMetrics(SM_CXSCREEN);
    int screenHeight = GetSystemMetrics(SM_CYSCREEN);

    // 计算通知窗口的中心位置
    int notificationWidth = 400; // 设置您希望的宽度
    int notificationHeight = 200; // 设置您希望的高度
    int notificationX = (screenWidth - notificationWidth) / 2;
    int notificationY = (screenHeight - notificationHeight) / 2;

    // 创建自定义通知窗口
    hNotificationWindow = CreateWindow(
        L"NotificationWindowClass",         // 类名
        L"Custom Notification",             // 窗口标题
        WS_POPUP | WS_VISIBLE | WS_BORDER,  // 窗口样式
        notificationX, notificationY,        // 位置
        notificationWidth, notificationHeight,   // 尺寸
        nullptr, nullptr, nullptr, nullptr   // 父窗口，菜单句柄，实例，附加数据
    );

    // 加载位图资源
    hBitmap = LoadBitmap(GetModuleHandle(nullptr), MAKEINTRESOURCE(IDB_NOTIFICATION_BITMAP));
    if (hBitmap == nullptr)
    {
        OutputDebugStringA("Error Bitmap Null Value");
        // 显示适当的错误消息或采取必要的操作
    }

        hNotificationWindow, reinterpret_cast<HMENU>(BUTTON_OPENURL_ID), nullptr, nullptr  // 父窗口，菜单句柄，实例，附加数据
    );

I am making a program that will send a custom notification sent for whatever I want. I have a window that shows up on the screen, but the image doesn&#39;t load.

I have tried using Chat GPT to check my code, but with its knowledge limit being Sept 2021 it doesn&#39;t know the new updates to API&#39;s to give me a correct response.

Code can be found below:

    #include &lt;Windows.h&gt;
    #include &lt;Shellapi.h&gt;
     
    // Constants
    #define WM_CLOSENOTIFICATION (WM_USER + 1)

    HWND hMainWindow;
    HWND hNotificationWindow;
    HBITMAP hBitmap;

        // Calculate the center position for the notification window
        int notificationWidth = 400; // Set your desired width
        int notificationHeight = 200; // Set your desired height
        int notificationX = (screenWidth - notificationWidth) / 2;
        int notificationY = (screenHeight - notificationHeight) / 2;
     
        // Create the custom notification window
        hNotificationWindow = CreateWindow(

Update: Here is a screenshot of my .rc file in VS. I have to see if I can find the file in my source files.

And here is what the program currently makes when you run it.
