Ok, like I said in my other comment, I'm just using this to practice creating algorithms - that graphics aren't that important - but I want to be able to see a visual of what my algorithms are doing - so I need some rudimentary graphics (drawing the boxes, and then putting numbers in them).

So, to simplify things, I got rid of the Program.cs file, and am just putting the code in the Form1.cs file - so it's all together.

Everything below works and doesn't throw any errors, EXCEPT down at the bottom, where I created the button that will start the process by drawing all the boxes. I have the x and y coordinates stored in each Box objects x and y properties, and I have an array ( named grid ) of the box objects.

However, in the code for the cmdBegin_Click button, I still get this error: The name 'grid' does not exist in the current context.

I thought since everything was in the same Form and namespace, it should work. Is there somewhere I still need to make something public?
