OpenClipboard,SetClipboardData,GetClipboardData are ok.
Would you please show me a hand?

   FuncPtr setClipboardData =3D null;
   FuncPtr getClipboardData =3D null;
   FuncPtr registerClipboardFormat =3D null;
   openClipboard =3D new FuncPtr("user32.dll", "OpenClipboard");
   setClipboardData =3D new FuncPtr("user32.dll", "SetClipboardData");
   getClipboardData =3D new FuncPtr("user32.dll", "GetClipboardData");
   registerClipboardFormat =3D new FuncPtr("user32.dll",
"RegisterClipboardFormat");
