我想用上面的代码，把一个叫做“InjectedDll.dll”的dll注入到notepad.exe中，这个是InjectedDll.dll的代码，我想在dll被注入的时候，可以弹出对话框
但是无论我怎么弄都不成功。没有弹出messagebox，接着我用windbg来跟踪notepad， 
我发现他的参数全部为nullptr，这是为什么呢?

```
这个地方已经给参数的呀。。。为什么不能成功注入呢？
新手求指教。

被hello,hook编辑
，原因： 排版有问题，重新排版

是的，notepad确实运行的是64位的，但是我还是搞不懂为啥注入失败。。。 |
|
|
代码没问题，我直接用的你代码测试成功了。 大概率问题是你的注入器编译的是x86的 |
|

我刚刚试了一下，又可以了。我所有的东西都没改，好奇怪。
这里编译出来的路径是在x64下的，而且我都检查了，全部是64位的。 |

真的是你说的这样的，我对比了下，那个dll的路径有问题。非常感谢 |

新手求问，DLL的程序是用txt写进一个.dll后缀的文件中吗，一直提示这个图片 请问应该怎么解决？谢谢 |

谢谢，确实是我还没有理解到位，再次感谢！
