Don't even think of changing your EXE file - that will get slapped by anti-virus products immediately!

Instead, look at using the Settings.Settings file to store your highlighted info between execution runs.
Open you project in VS, look at the Solution Explorer pane, open the Properties branch, and double click on Settings.Settings
In the page that results add a new setting.
You can then access the value in your code via

C#

... = Properties.Settings.Default.YourSettingName;

And save it by using:

C#

Properties.Settings.Default.YourSettingName = newValue;
Properties.Settings.Default.Save();
