Okay Chana,
Look what you should do...
1st look for any samples that is online and download their codes.
2nd modify the code and study how it was writen.
3rd get the latest technology in to your knowledge.. such as Silverlight, WPF, and use Expression Sudio especially Expression Blend where you build your silverlight and WPF application.
4th use Visual Studio, and if you dont have much knowledge of it, download it and start working in it using VB or C# languages..
thats all for now..
Cheers,
Roudi H
