some programmer look here

hello to all
 excuse if I'm doing something wrong.
 I have broken my head, without success.
 Could someone help me with this, what to do
 I need to kill the thread of a dll
 as shown in the video
 the application shown in the video
 kills the thread xtrapva.dll.
 if someone could,give me a light
 if someone can create a source code
 with the same function shown in the video
 I would be grateful
 it would just be gratitude
 if I'm wrong then just close the topic
 humility always
 thank you
