英文:
Image generation in a New Window
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：

// 计算通知窗口的中心位置

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't load.
I have tried using Chat GPT to check my code, but with its knowledge limit being Sept 2021 it doesn't know the new updates to API's to give me a correct response.
Code can be found below:
#include <Windows.h>
#include <Shellapi.h>
// Constants
#define WM_CLOSENOTIFICATION (WM_USER + 1)
#define BUTTON_OPENURL_ID 100
#define BUTTON_CLOSE_ID 101

void ShowNotification()
{

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.

**得分**: 1
切换到 GDI+ 而不是位图，它立即起作用。
感谢 @jwezorek 的帮助。

Switched over to GDI + instead of Bitmaps and it worked instantly.
Thank you for trying to help @jwezorek.
