Rajesh,

I read your last posted code.The picture arise in my mind is that you consider people here that they are totally free for you & if you did not give them assignment,they have nothing to do.No dear that's not true.We are more than busier than you perhaps 100 times more than busier than you.My intense only is to give guidance to the people who come here with hope of getting help from here because I was also sometimes in the stage as you are at present.So remove from your mind that we whole day surfing for what's the new assignment posted here or not from you.I think you are fortunate enought to get this kind of 'luxuray' at this stage.So respect the thing what you get from here.Don't devalued it.

About quality of the code I last posted here for explanation to this student it was my effort to get rid him from the trouble.The thing is that whether this student learned from that code or not is totally insignificant for me.But I learned many things from him what to do & what not to.

Thanks
Maunik
