Google doesn't work where you live ? A clue, you've already found the best one...

If you really want to learn, you need to buy a book. The web is good for building your knowledge, books are better for starting off.

You can also use VB .NET for web application, as I imagine it would be easier for you. But without doubt, it's worth learning C#.

Hey Kumar,

You are in the good place. There are lot of Articles here itself.

But as our expert says first get a book published by wrox publications for Asp.Net C# and read it and start practicing it.

FOr more Details get it from our Friend Google,but it will be very much helpful for you to develop your knowledge.

So my better advice is first get a book and start reading it and start practicing the code it will be very much useful.

Hi EveryBody! sorry for the trouble, I have a problem, for delivry of my thesis by ten days.
My problemi s that:

I would like to manage onmousemove, onmouseup, onmousedown events on the web document opened in the browser.

I used the following code for that.

public delegate void DHTMLEvent(IHTMLEventObj e);
public class DHTMLEventHandler
{
//DHTMLEvent è un delegato

public DHTMLEvent Handler;
HTMLDocument Document;
public DHTMLEventHandler(HTMLDocument doc)
{
this.Document=doc;
}
[DispId(0)]
public void Call()
{
Handler(Document.parentWindow.@event);
}
}

DHTMLEventHandler Handler1;
DHTMLEventHandler Handler2;
DHTMLEventHandler Handler3;

public void controller_seleziona()

{
mshtml.HTMLDocument doc = this.br.Document as mshtml.HTMLDocument;

object old_move=doc.onmousemove;
if(old_move.GetType()==typeof(DHTMLEventHandler))Handler1=((DHTMLEventHandler)old_move);
else doc.onmousemove=Handler1=new DHTMLEventHandler(doc);
Handler1.Handler+= new DHTMLEvent(controller_Document_onmousemove);

object old_down=doc.onmousedown;
if(old_down.GetType()==typeof(DHTMLEventHandler))Handler2=((DHTMLEventHandler)old_down);
else doc.onmousedown=Handler2=new DHTMLEventHandler(doc);
Handler2.Handler+= new DHTMLEvent(controller_Document_onmousedown);

object old_up=doc.onmouseup;
if(old_up.GetType()==typeof(DHTMLEventHandler))Handler3=((DHTMLEventHandler)old_up);
else doc.onmouseup=Handler3=new DHTMLEventHandler(doc);
Handler3.Handler+= new DHTMLEvent(controller_Document_onmouseup);

}

It's all ok unless I also want to manage drag-drop over a div appended bymyself on the dom of the page.
To manage the drag drop I appended dynamically the javascript library wz_dragdrop.js v. 4.88
The latest version is available at http://www.walterzorn.com

Now the situation is that the management of onmousemove, onmouseup, onmousedown events on the document builded bymyself continues to work fine, but the drag-drop of the div doesn't work anymore, unless I don't handle the management of onmousemove, onmouseup, onmousedown events on the document anymore. If I don't handle the events, overthat if I don't call the method controller_seleziona then drag-drop work fine.

Even if I handle the management of onmousemove, onmouseup, onmousedown events and then in a second moment I remove that management with the code:
Handler1.Handler -= new TMLEvent(controller_Document_onmousemove);
Handler2.Handler -= new TMLEvent(controller_Document_onmousedown);
Handler3.Handler -= new DHTMLEvent(controller_Document_onmouseup);

The drag-drop continues not working.
Is there a way for let drag-drop live together with my personal handling of the onomousemove,onmouseup, onmousedown events on the document ?

Thanks in advance! I hope in some help please. I'm bit worried

Receive() is a blocking method i.e. it won't return untill it has received some information. So it will wait indefinatly for a message if there arn't any.

You can specifiy 'TimeSpan timeout' in one of the method overloads that will allow you to return after a set time limit if there is nothing to receive.
http://msdn2.microsoft.com/en-us/library/system.messaging.messagequeue.receive.aspx[^]

If you want to carry on doing other work whilst the Receive() is waiting you can do an asyncronous call using BeginReceive():
http://msdn2.microsoft.com/en-us/library/system.messaging.messagequeue.beginreceive.aspx[^]

Another option is to use GetAllMessages():
http://msdn2.microsoft.com/en-us/library/system.messaging.messagequeue.getallmessages.aspx[^]

I am currently attempting to write my first program for out company. What the program is to do is to pull all the local information of the network and SOMEHOW be able to tell the user their WAN ip or if no ip is found meaning the internet is down, it should say No WAN IP call ISP.

i have provided you with my code here to see if you can help me understand how to get this information.

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;

namespace WindowsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

private void label1_Click(object sender, EventArgs e)
{

}

private void Form1_Load(object sender, EventArgs e)
{

}

private void check_Click(object sender, EventArgs e)
{

}
private void Form1_Resize(object sender, System.EventArgs e)
{
if (FormWindowState.Minimized == WindowState)
Hide();
}

private void contextMenuStrip1_Opening(object sender, CancelEventArgs e)
{

}

private void toolStripMenuItem1_Click(object sender, EventArgs e)
{
{
Show();
WindowState = FormWindowState.Normal;
}

}

private void notifyIcon1_MouseDoubleClick(object sender, MouseEventArgs e)
{
{
Show();
WindowState = FormWindowState.Normal;
}
}

}
}

I have a picture of the program if need be

Hello,

May be this project[^] will help you. This is the OpenGL wrapper for C#.

This OpenGL framework for .NET is very good: http://www.taoframework.com/[^]

To get started put a TaoPanel(I think that's the name of the control) on your form and inside it's OnPaint event handler do all your OpenGL stuff.

Christian Graus3-Jun-07 23:52

3-Jun-07 23:52

You keep posting this, and you keep saying 'I want a drawing program', not 'I want to write a drawing program'. Which is it, do you want help writing one ( ask more specific questions ), or do you just want one ( this is a board for asking questions with your code, not looking for complete code )

OpenGL is a 3D framework. It's not really useful for a program like this one, in fact, apart from a bizarre way of achieving layers, I don't see how OpenGL would help you much at all.

You're not going to find it here. This is the right place to ask if you're writing a program and have specific questions to help you do it. If you need to find a program, you probably have to pay someone to write it for you, if you can't find it with google.
