From VB6 to ASP.net?

Hey Everyone...

I was wondering how hard it would be to convert the following attachments into a web application? the attachments are my program...

I've been playing around with ASP.net. When I switch from HTML, to design, I can see the textbox I have created..but when I run the program in IE...it doesn't display it....and the only way I can get this to work is by clicking "start without debugging"...when I just click start... it gives me an error....I've also attached a screen shot of the error.

It is only 1 form....at screen1...you enter a number.....then hit the enter key...(there is labels that are invisble on this form)...then once you hit enter....it displays screen2...what is happening is it hides the labels that were on the first screen....then when you click "new"...it hide the labels that were on the second screen..

So anyway...All the program does is.....calculates 4 number depending on the number you enter in the textbox....if the number entered is < 4.5 the label flashes ***TPS: TOO LOW***, and if the number is > 5.5 the label flashes ***TPS: TOO HIGH***. If the number is in between those 2 numbers then the label is solid and doesn't flash... ***TPS: CONFIRMED***


Thanks for the help in advance!!
