Make calculator in .net

There are number of calculators available . If you want to make a Basic calculator in .NET Then you can surf a number of Calculators code on the Internet .

I have tried a simple calculator That only does Addition , Substration, Division and Multiplication of integers and Fractional numbers .

FROM VB6 TO VB.NET

The switch form the old visual studio versiom6 to newer Visual Studio .NET to Create Visual BAsic
programs represents a update in technology . It represents far more than changing of a version name. When upgrading from Visual Studio 6 , Instead of naming it version , Microsoft used the term .NET as the name of the new version to denate the difference that it carries from the older technology .Faculty members teaching programming courses in visual  basic have to learn about the changes in new version of visual basic in order to Switch from teaching the older vb6.
