How to MultiSelect in a Open Commondialog Control...

Hi Guys,
What should I do so that i can select more than one File(s) in a common dialog control. For example in Winamp or Windows Media Player you can select more than one file by Pressing Ctrl + Click by mouse or Shift + Up (or) down Arrow by keyboard. And I would also like to know that how will it return the file names. for ex. while selecting a single file we can get like ,commondialog1.filename=something.filename . Any help appreciated greatly.
