hi

Vulpes
without using script and only using c# web app we cant write code for that 

hi kiran,

i finally found the source code of ncalc. i am attaching the source code just check that.

Try using the Microsoft Script Control.

First add a reference to your project to the Microsoft Script Control 1.0 which can be found under the COM tab.

The code to use it will then be on the following lines:

    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            var sc = new MSScriptControl.ScriptControl();
            sc.Language = "JScript";
            Session["ScriptControl"] = sc;
        }
    }

    protected void Button1_Click(object sender, EventArgs e)
    {
        var sc = Session["ScriptControl"] as MSScriptControl.ScriptControl;
        try
        {
            TextBox2.Text = sc.Eval(TextBox1.Text).ToString();
        }
        catch
        {
            TextBox2.Text = "INVALID FORMULA";
        }
    }

hi kiran,
