}along with this .. i have a file .. which contains .. all the questions and options and along with it it contains the correct answer from all the options .. the file which has all the questions .. is like this
Who Made Java ? &Oracle&Sun&Microsoft&Intel&2&Where is London ?&US&UK&France&Australia&2&it contains all the Questions and options related to the question separated by the "?" sign. .. I'm reading the data from .. the file and storing it in a double dimensional array .. so that .. it can be .. allotted to the given form ..
the problems .. I'm facing are
the program is not skipping to the next question..after 20 seconds ..and shows the same question and the same options again .. after 20 seconds ..
please help me in this ... if u need anything else .. like the file operation code s.. let me know
