This example associates the private clipboard format "MyFormat" with the object class "MyObjectClass".

 HATOMTBL   hAtomTable = NULLHANDLE;
 ATOM       aFormat = 0;

 /* Find the system atom table  */
 hAtomTable = WinQuerySystemAtomTable();
 if (hAtomTable)
 {

    /* Add an atom to the system atom table for the clipboard format  */
    aFormat = WinAddAtom(hAtomTable,"MyFormat");
    if (aFormat)
    {

       /* Associate the clipboard format to the object class  */
       _wpclsAddClipBoardAssoc(_WPDataFile,aFormat,"MyObjectClass");
       WinDeleteAtom(hAtomTable,aFormat);
    }
 }
