Ok, so at work we have some software which allows Wake-On-Lan (WOL). However, the company is getting rid of this software and replacing it with software that does NOT support WOL. So, I decided to write my own program to do this for us.
However, it just doesn't seem to be working. This COULD be a problem with the target computer (Can't seem to get our current software to wake it either)
Also, right now it only supports MAC addresses, still working on Computer Name and IP Address functionality.
I've attached the entire project as well

I don't know why, but it removes spaces in my code when I post..... not sure what's going on there,.....

The code has snippets from other sources I found, plus my own code. Like I said, still developing, so a little bit sloppy


Side note:
I'm back again lol. Sorry I've been gone for so long!
