I wrote this program to retrieve all the contents of a hard disk in c# application. Now i want that it must be retrieve all contents on background and must show me a progress bar on a form. I want my application should run as background service i.e it must not be closed after pressing X on the form and must be minimized in the taskbar's left corner as in windows xp.
Additionly,It would be appreciable if any could tell me that how can i make this generated cache fulltext indexed in sql server 2005. I don't have the full text services installed so please provide me a link for downloading separate files for sql server 2005 to install freetext in it.

Yours Sincerly,
