How do i save program state?

I'm new to this forum, so please tell me if I'm posting in the wrong place...
I am making a program for my workplace. The program is going to close explorer.exe on start up and launch only applications i select. (I know that there are other ways to do this, but I'm getting paid to make a custom program W/ Co. Logo)
-------------------------------------------------------------
1st question: How do i make the program close explorer.exe on start up


2nd question: End users will be able to change the background of this app. My question is, How do i save the background the end user pick on program exit and load it on program start?


any code will help..... thx in advanced, Jake.

Next time, wrap your program's code in [code ][/code] blocks. helps out a lot.

1st Question: Don't recommend this, but it looks like you're working on an....explorer rewrite? I don't recommend doing this step until your program is more stable.

2nd Question: Look into My.Settings

or even better wrap in [H IGHLIGHT="vb"][/H IGHLIGHT] ... with out the space between h and i ... to syntax color
