I have a few questions before i release my program, they are:

1. I want the user to have the abilty to press a button that will extend the size of a form revealing 2 web browsers because the form just looks to cluttered with them showing all the time. but i want them to be able to press the button again so it will now make the form go back to its oringal size(not showing web browsers).

2. This problem has been bugging me for a long time, i have tried for hours to find the solution but i cant. This is what i need to do. I have 2 text boxes, and the user enters a number in both boxes. I need to take the first number and add 100 to it until it gets to the number of the second text box. For example if the forst text box was 100 and the second text box is 1000. i need to go 100,200,300,400. SO each time the timer is activated it adds an aditional 100 to the number until it gets to the number of the second textbox.

3.I need to stop people form hexing my program. I mean just the text part, so they cant change my labels and things like that. Is there a free program that does this?

Thank you very much
