Hard coding a path that only exists on your development machine
MyPath = "C:\Foo\Bar";
Let's faced it. This is just lazy. It doesn't matter if you are the only one working on the project. You will eventually move to another machine or someone else will be added to the project. Next thing you know you're pulling your hair out trying to figure out why it works on one machine but not the other. By hard coding the path you've created a dependency on the exact folder structure of your hard drive.
What's worse is that you're not only forcing this on yourself or another developer but possibly the end-user as well. Save everybody some frustration and use paths relative to the main executable or if warranted, make the path configurable by the end user.
