how could i make my main prog looks like "MY EXPLORER"

Good day to everybody,

Maybe i miss this topic,..is anyone can guide me where i could find the sample for this matter.

How could i make my application, that when you click the icon at the disktop it opens like you are opening the "MY COMPUTER" using 'explore' that shows drop down list, but instead of showing the drive c, cd-rom drive and e.t.c it shows all your form's name (ex. salaries, sales entry & e.t.c then a drop down for reports) very similar to the project manager itself.

any help is very much appreciated...Thank you very much
