the VC++ compiler said the following words, when I compile the sample application, (2 errors)

if exist"\Symbian\6.0\NokiaCPP\EPOC32\BUILD\SYMBIAN\6.0\NOKIACPP\EPOC32EX\CRYSTALUI\CUSTOMDIALOG\CUSTOMDIALOG\WINS\UDEB\CUSTOMDIALOG.exp" del "\Symbian\6.0\NokiaCPP\EPOC32\BUILD\SYMBIAN\6.0\NOKIACPP\EPOC32EX\CRYSTALUI\CUSTOMDIALOG\CUSTOMDIALOG\WIN
S\UDEB\CUSTOMDIALOG.exp"

what does the above mean? Why I cannot compile it??

Thanks!

Joe
