I am going to edit this post.
This post has been edited five times. There was no modified additions after the first edit, but it did appear after the second. I'm guessing there's a window within which they don't appear. As to why they don't appear on the OP's post I'm not sure. I'm not making this stuff up, the post was edited: My post contains text copied from it using the clipboard and I provided a link from the poster where he says he did. I'm not sure what more I can do to convince you.
Well I don't think he did. If a post is edited after being created, then it gets the tag [modified] added to the title, and a date put in at the bottom, as you can see in my modified post[^], or indeed, in your first reply to me.
This does not always happen, Richard. I would say 15-20% of the time, old posts that I modify show no sign of change.

Here is my source code for locking my computer screen (Generally we do by pressing win+L)But Here in the below code what i am trying to do is , when user run the exe created by this application 1st the screen will be invisible (which is not happening in case of win+L) then next time when the user interact with the system it will show the user that the screen is locked .
int APIENTRY WinMain(HINSTANCE hInstance,
// Turn off monitor
Sleep(500); // Eliminate user's interaction for 500 ms
ret =SendMessage(HWND_BROADCAST, WM_SYSCOMMAND, SC_MONITORPOWER, (LPARAM) 2);
