SmartCalc : Screenshots

Introduction

This lite calculator, written in VB.NET, not only can be useful for installing on your smartphone as a real powerful scientific calculator, but also, can be used for learning some good ideas which I've learnt while developing it.

Background

Although I have no Smartphone, Once I decided to develop a nice and useful calculator to see how .NET compact framework works on a real Smartphone, [ since after a while i could find a real Smartphone to get this tiny calculator installed on. ].

the result can be interesting, specially for those decided to write their first .NET compact framework application.

Points of Interest

When I decided to develop, I was thinking that .NET compact framework, has some namespaces and classes, which might be used for runtime compiling, in-memory compiling, and runtime evaluating mathematics [ codes, in general ], just like .NET framework has. but I'd found out that there is no !, so decided to find a solution for doing that. many many classes were written in VB.NET and C#, which could do that, but all of them have dependencies to Microsoft.NET, not Microsoft Compact.NET. after searching and searching and searching ... I finally found Math.NET library, which was developed in C# and under license of GPL [open source]. yupp ! this one, finally solved my problem.

I used Math.NET Classic cause of its simplicity and lightness. More and more functions and routines could be found in this framework, and could be used to extend SmartCalc's functionalities.

I'll be glad to be informed of any changes you may make in SmartCalc. Also, I would be very thankful if you could share the changed source with me.

Thanks Dear GCRTA:
I'm glad to see that this low weight calc pleased you,
 
1) About the start icon, you're right. I forgot it since I have not access to a real device for a long time.
 
2) This program is a SmartPhone Application, althoght it can be run in .NET Compact Framework, in both SmartPhone and PocketPC, It has been optimized for SmartPhone.
 
3) Since the framework is the same, this application can be easily matched and optimized with PocketPC, and surely I'll do that, since as you said, It can be useful for many many users ...
 
4) This way of switching is the best way I found, although It cant be absolutely OK, but I'm sure it would bother you if I had designed it to lock the status of "MODE" key. so, there surely should be and will be a better way for switching of function keys. I'll think ... but also all of you, dear readers and tester, would be better to help me to find be better solution. so, I'm waiting for your suggestions.
 

Thanks again,
Regards, Mehran
 
.NET is the taste of life !
