Hi
use array of button to make calculator then assign code on button click, on the base of index process the request.

if you are not stick to server side programming you can use javaScript also to make nice calculator.

Perhaps a look at this thread and the links you find in it could help?

Well congratulations everybody on just handing out code to someone. My particular favorite was this one:

Button1(.................)
{
Process p=new Process();
p.startInfo.FileName="calc";
p.start();
}

That being said... when someone comes to the forum and says "please help me with the code behind file..as i am really confused...otherwise give me some tips to start doing the code" do you think that they benefit more from having completed code snippets dropped in their lap or from being told how to go about coding the application they're working on?

DangerDev and ddanbe good on you two for pointing the user in the right direction :twisted: At least some folks are still following the 'developmental learning' model around here as opposed to the 'here's a free hand out, go turn it in to your teacher' model.

Now as to the original question, similar to ddanbe I'm going to provide a reference to another thread. Perhaps the information in that thread will help you sort out your calculator code issue.

@Lusiphur this is not code its just cheating :p

[aizalee]

Hi hassan12345
I have created the calculator already with the codes in aspx page,

Really? You think the original poster is still looking for code after 3 years?

[Zvjezdan23]

@ Lusiphur: I am a beginner as well and I am also learning c# by myself now. I have a book on ASP.Net 3.5 and Silverlight 3 as well. i really think that these guys that have typed out the code and posted it on here help out a lot. Beginners like myself like that people like these guys and gals are willing to post up their code on here. We "noobs" (if you will) like to learn from the professionals because we do need help. I needed help on a Yahtzee game in c++ a while back and a couple of guys and gals really helped me out. They made some code for me and I intertwined it into my code. They helped me with resizing the screen and a little bit of the scoring function. When you have completed code like this, I myself can understand what's going on and try to fill in the gaps myself; if not at least make some adjustments from their code and maybe re-write their same code over so I can have it in my head. We like to use references when we are in school and I love it when others see that we really do want to learn. So Thank You all that have ever posted up code as well as complete code in these forums. God Bless All of You and Your Families As Well.
