Please Help - Need Help with Buttons for GUI for assignment. URGENT!!

Oh it's urgent. No probs, I'll drop everything just to do your work so you can sit back and relax because you are more important than me or anyone else here who is asking for help.

Do you know what stating "URGENT" does to the volunteers here? You're about to find out. It usually gets the pissed as hll (if American English is not your native tongue, that means very very mad).

It is like you are telling us that your problem is more important than any other poster's problem here. Most here will tell you that it's not.

It is as if you are telling us that we must drop everything that we are doing to attend to you because you are more important than us. Most will tell you that you're not.

It is as if you are telling us that because you are late in finishing your project, that your urgency becomes our urgency. Most here will tell you that it does not.

If you want prompt help, then skip the URGENT!! Rather ask a good question. That is, a question that is well thought out, that asks help on a specific problem, not some general vague problem such as "help me with the buttons on this program".Ask a question that shows that you have put real thought into asking the question.

Good luck

Describe your requirements and the current problems you have regarding them. What on earth your buttons should do?

Nayak, we are all impressed with your coding abilities and especially with your use of code tags.

Have you ever been to Yosemite National Park? It is one the most beautiful spots on earth. Well if you do go there, you'll see signs posted "do not feed the bears". And there are good reasons for this, not just that if you get close enough they could tear your limbs off. No, if you feed them, they don't learn to feed themselves. They learn to be lazy. They learn to beg for food.

Just like the bears at at Yosemite, you shouldn't spoon-feed the newbies. It teaches them to be lazy. It only motivates them not to think for themselves. They even forget how to think. So remember please, spoon-feeding != teaching. Also, they might just tear your limbs off.

Have a nice day.

Thats not a good design. You just create the field at a reasonable size to begin with. You forms should not change in size just because you scroll from one item to the next.
