The problem is your BMP cannot be found. Put it in the Release or Debug folder (depending on which you're running) and it will work.
I just tried it and it works fine.

see the project I attached in the previous message.
It can't magically find the image on your desktop 
How does it know it's there? Either provide the full path to it, or move it as I suggested.
I moved as suggested and yes it works, thanks for all the help, I was looking in the wrong folder.

No problem Keep at it. I did quite a bit of graphics on WinForms not so long ago (although it's outdated, it's still very useful for learning and rapid development). I'm prototyping a game in it right now.
I am still working on my blackjack game but I am using graphics. thanks for all the help.

No problem. BTW you should dispose() the BMP you created. Rule of thumb is to dispose resources you create (at the right time) and not those you don't create.
here is my updated code, is there anyway I can streamline my code so far.
private void Form1_Paint(object sender, PaintEventArgs e)
{
Graphics g = e.Graphics;
Bitmap bitmap_two = new Bitmap("c02.bmp", true);
Bitmap bitmap_ace = new Bitmap("c01.bmp", true);
g.DrawImage(bitmap_two, 20, 20);
g.DrawImage(bitmap_ace, 40, 40);
g.Dispose();
}

Yes but beware premature optimization
Don't dispose the graphics object. You didn't create it, you're only aliasing it by assigning to another variable.
About the only thing I'd add at this point, is to surround the bitmap creation/usage in a using() statement (but not the Graphics g = part).
edit: ok another general thing, don't use hard-coded strings like "c02.bmp". I know it's only early but I think this is worth mentioning early so that you apply that to all your code as you write it. Either create a constant for it, or better, store and look it up somehow. I'll leave that to you.
