When trying to compile my first window for OpenGL, I get these linking errors:
--------------------Configuration: Lesson1 - Win32 Debug--------------------
Linking...
LIBCD.lib(crt0.obj) : error LNK2001: unresolved external symbol _main
Debug/Lesson1.exe : fatal error LNK1120: 1 unresolved externals
Error executing link.exe.
Lesson1.exe - 2 error(s), 0 warning(s)
seems like someone is trying to compile a windows program (WinMain) in console mode (main), change the project to create win32 app

Ok, thanks. That solved that problem:
--------------------Configuration: Lesson 1 - Win32 Debug--------------------
Lesson 1.exe - 0 error(s), 0 warning(s)
But now when I try to run it, I get a pop up window that says:
Cannot Execute program

Wow, that almost sounded as if you did not programme that app/game for yourself! 
"I get a popup box" is what I meant.
If you take a look at your code, you''ll probably find a piece saying "if error blablabla: MessageBox(This is the popup you saw)"
So just look up in your code what the cause is of the error, it could be things like problems with going to fullscreen, not being able to make a hDC or whatever :D it could be a lot of things. I advise you to change the message the messageboxes (or popups) give you when an error occurs, so you know immediatly what is wrong... It really helps when debugging and when people report errors (you can do a lot more with "i got an error when going to fullscreen" than with "it said the game had an error"
get what I mean? I think (but I might be wrong) you haven''t readed the code too well, since you didn''t figure the above yourself. Nothing wrong with that, a lot of people don''t really exactly ''know'' the lesson after their first contact with it, but I advise you to study Lesson 1 very well since it''s a really big one for a beginner (it took me a week
) and you''ll have to use it in every game you''ll ever make with OpenGL... (no we won''t use GLUT 
)
It''s better to waste a month on that lesson and understand it perfectly than hurrying the lesson and having to face all those weird bugs and stuff the rest of your programming career without knowing what the problem is.
If you don''t understand certain parts of the code, you can of course always ask here what the code does, and why.

Actually, I already did a search for that string, and it isn't in the code. This is something Visual Studios is thowing up (I can tell this because he has all of the error window titles set to null, and the window that pops up has a visual studio c++ title), not my application.
This is the tutorial strait from NEHE.com. Of course I didn't write it. All I did was look at the comments and followed along with the tutorial.

"Cannot Execute Program" is definitely not something that comes out of NeHe''s code.
I suspect that something has happened, such as the executable is access-locked for some reason, or something. MSVC just can''t get permission to read it(i think). Try the General Windows Fix the Damned Thing Solution(tm), ie restart.

The sad thing about artificial intelligence is that it lacks artifice and therefore intelligence.
Democracy is where you say what you want and do what you''re told.

right before this window appears, another comes up asking if I want to create a debug folder
c:\program files\microsoft visual studio\myprojects\lesson 1\debug\lesson 1.exe
this file does not exist. do you want to build it?
yes no
i click yes, then get the other window.

I figured it out!!!!!!!!!!!!!!!
I was trying to run it strait out of a zip file. it could''t make a file inside a zip folder.
