thanks.

Dear , I am already working on 32 bit base. I think this might be problem in Libraries Included. This code requires more Libraries to be included to recognise all functions and datatypes which are being shown undeclared before.
If there is some other problem ,kindly suggest me the right way to solve it.
thanks.
