C # disable closing and dragging forms. [vulnerability]

 

* I also copied it from others. It is okay to disable it. Of course, you only need to disable it in the Process Manager. Haha

If you do not want to drag, you can use the icon menu on the left of the title bar to drag the form.

[The solution should be this. position]
