Read in Text File and replace large portion of text?

[KingPacino]

I have a .reg file which holds several variables one of which is a Search Path which has lots of different paths.

The program I have written populates a TextBox from a checkboxlist which holds the paths so the ones selected appear in the TextBox. I want the Search Path in the .reg file to show the paths selected in the TextBox.

How can I replace these search paths in the .reg file to show the selected paths which are in the TextBox?

Once the file has been updated the program gives the user a download option to then update the registry with this file.

Is this the best way, I have read a little about registry manipulation perhaps this would be better?

Any thoughts or ideas would be greatly appreciated.

Thanks
