Sample Code:
//Displays the id and name of the all the different data formats currently in the clipboard.
//Create a project called ClipBoardTest, a form called Form1 and add two buttons (button1, button2) and two listboxes (listbox1, listbox2).
//Clicking button1 will copy the id and name of all the clipboard formats in the clipboard to listbox1.
//Clicking button2 will copy everything from listbox1 to listbox2. This is useful if you want to
//compare the clipboard formats used by two different applications.
