VS 2010 [Help].Txt file to CheckedListBox problem

I am making a cheat code program and I have a problem, the way it works is the cheat codes are imported into a CheckedListBox from a text file so you can check which ones you want and export them in the correct file format.

What I need help with is the text file is supposed to be in a certain format like this and when I open the text file it shows every line in the CheckedListBox.

Line 1:Game ID
Line 2:Game Name
Line 3:(space)
Line 4:Code Name
Code contents(however many lines the cheat code is)

I need the CheckedListBox to only show the Code Name's. Then I need the code contents to appear in a separate TextBox when I click the code name in the CheckedListBox. So maybe make it to where it only adds the line after each space to the CheckedListBox.

I am pretty confused, I would be very grateful if someone could help me out. I hope my explanation wasn't to complicated.

Thanks.
