How do I get my program to check that a string contains only numbers? Any help would be nice.

There are lots of ways to do this:

1. In your project you can add a reference to Microsoft.VisualBasic and use the IsNumeric function that is contained within that Namespace.

2. You can loop through the string char by char and call Char.IsDigit()

3. You can use regular expressions to determine if the string contains only numeric values.

Also consider TryParse method of your numeric data types.
EG
double.TryPass("1.54",result)
