vb.net - Editing hex of code of an application

Question

I have recently seen few application where I can edit certain blocks of hex by giving the valid offset.

The question is, how do they do that? Are there any function which allow binary string editing in vb.net?

There is no much about that on google, so could you tell me how can I edit the application source in vb.net like in the hex editor?

Answer 1

看看这个：

1. 致电File.OpenWrite获取FileStream您的文件

2. 设置Stream.Position跳转到要编辑的位置

3. 调用Stream.Write以覆盖文件中的字节。
