Yes, that is possible. Try this little horrorcode;

string asXML = @"<codinghorrorxml>" + Environment.NewLine;
asXML += @"<textbox1>" + textBox1.Text + @"</textbox1>" + Environment.NewLine;
asXML += @"<textbox2>" + textBox2.Text + @"</textbox2>" + Environment.NewLine;
asXML += @"<textbox3>" + textBox3.Text + @"</textbox3>" + Environment.NewLine;
asXML += @"</codinghorrorxml>";

You'll also need to write this string to disk, I presume. There's a StreamWriter somewhere in System.IO.

you're not writing XML. Stop flailing about in the dark, abandon the path of ignorance, and actually do some work to establish that the code you enter stands some semblance of a chance of working.

Well, I'd recommend you do some reading on XML, and possibly C#. You either are hoping for some sort of magic to happen that has nothing to do with any code that you've written, or you plain have no idea. You've not written any nodes here, this would only work if you magically happened to type the right values into your textboxes to create XML. Either way, as the original guy said, this is horrible code. XmlTextWriter is the class you should be using. I've confirmed that there's tons of info and examples on the web, easily found with your search engine of choice.

is it possible to have a click event that takes three paramenter i:e

private void MyButton_Click(object sender, EventArgs e,int xyz)
{

}

if yes then how?

thanks

Eddy Vluggen19-Dec-08 22:44

Yes and no. That not what you wanted to hear, but let me explain;

You can't change the way that a standard button uses to signal a click. Trust me, that's a good thing.

You can make your own button however, and fire your own custom event. You'd have to create a delegate and a matching event.

Throughout the .NET framework you'll find that most events are based on TWO parameters. The first one being the sender, the second one the arguments. That's done for enhanced readability. If you want to send an extra param, then you could derive from EventArgs and pass those.

My apologies for deepening the confusion Smile | :)

It is not possible with Button class, the EventHandler delegate is defined like this:

public delegate void EventHandler(
	Object sender,
	EventArgs e
)

Implementation of logarithms in asp.net

19-Dec-08 23:34

To add to what others have said. Assuming you added this parameter, what do you hope it will contain ? Where could it come from and how ?

The way things work in .NET is that there's always two params ( as someone else said ). To clarify, if extra info is needed, a class is used derived from EventArgs, such as MouseEventArgs, send with a mouse event and containing pertinent information. Just for clarity, it would be wise if you create a custom button, that you create a custom event args instead of adding extra parameters to the list.

if i specify log2 base10 i should get the log value which matches the log table

Lev Danielyan19-Dec-08 22:51

Lev Danielyan

What do you mean log2 base10, log2 is base 2.

You can use the log static functions defined in Math class:

Math.Log(double a)
Math.Log(double a, double base)
Math.Log10(double a)

We have an ASP.NET forum ( of course, you asked there ), but this is not an ASP.NET question. Sounds to me like you need to focus on some basics, and learn the frameworks you're using.
