C# Visual Studio Translate to MonoDevelop

[PeterAndrewStephenson]

I have written a program in C# that takes in integers from a text file and displays then on a form_paint as dots, basically what i am doing is a GUI which shows an area with three access points and wireless devices what i want to do is:

1) Translate the code that i have written from Visual Studio to MonoDevelop
2) When i hover my mouse on top of one of those device, i need it to show me details about that device, like:
i. mac address
ii. device name

A general guidance on how i can do this would be very much appreciated thank you

What happens when you try to run it in Mono? As far as I know, Mono supports forms without issue.

Just some general code guidelines, StreamReader realizes IDisposable, so you should use it in a using block. At the very least, you should use it in a try/catch/finally block to ensure the file is closed:

using (var file = new System.IO.StreamReader(...))
{
... // no call to Close() needed
}

or like the example here.

I'm not sure how you're generating your x,y coordinates, but it seems they should be in a single file, not in two separate. In fact, you probably want to use a Tuple or similar (KeyValuePair, struct, a data holding class, etc) for your x,y coordinates.

Rather than using a magic number for when the counter is done, you should check the length of x or y. Otherwise, if you want to increase the size of the array in the future, you have to find the magic numbers you used and update them everywhere. In fact, you probably want const ints to define the size, so that you can't have x > y or y > x.

There's more, but that should be enough to get you started.
