If I understand what you are doing, problem is that you can't "write" picture into page. Pictures are NOT part of the page. What you need to do is generate your .jpg file on server, and using ajax set the image source to something like
<img src="givemepicture.aspx?picture" />
And givemepicture.aspx will write your image (probably generated using parameters passed in url) into its response. I don't know if the browser will automaticaly reload image after you change it's src with javascript.

In my site I have used ajax technology . What I want is to prevent the user from doing anything on the page while the data is being fetched from the server using ajax. I don't want the user to be able to click a link , etc . Is it possible to do it in one place . Any Idea ??

while processing, you should display one overlay image on the screen..
You can check the technique which is used in open source *box[^]

I start using the TreeView web control. I feel the default spacing between leaf nodes is quite big. I want to reduce the spacing so that I can fit more nodes. Is there a way to control the spacing(reduce to the min., rather than increase) ?
I have tried setting all "NodeSpacing" and "VerticalPadding" to 0px. The spacing is still too big for me.
Thanks in advance for any suggestions!

Hello. Here is my situation. I'm building a client asp.net application that will reside on our DMZ. I have a web service (called "ServiceBus") that acts as a single access point through a single port to our data center.
The ServiceBus has methods that do several tasks such as fetching data, running SSRS reports, streaming documents, etc. Everything works fine when testing my client app from within the domain but from the DMZ I get authorization errors (see subject line).
The following line of code will get me to the HelloWorld method but any other method that fetches anything from another server fails with permission errors:
serviceproxy.Credentials = System.Net.CredentialCache.DefaultCredentials
So it seems that I need to send domain user credentials which I try below.
I have IIS security set to Digest. The code below was suggested on this post:
http://forums.asp.net/p/1050587/1862246.aspx#1862246
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load<br />
Dim serviceproxy As New WSBus.ServicesBusWebService()<br />
Dim userCredential As NetworkCredential = New NetworkCredential("username", "password", "domain")<br />
Dim credentials As CredentialCache = New CredentialCache()<br />
credentials.Add(New Uri(serviceproxy.Url), "Digest", userCredential)<br />
serviceproxy.Credentials = credentials<br />
serviceproxy.PreAuthenticate = True<br />
<br />
Dim response = serviceproxy.HelloWorld() 'BREAKS HERE<br />
lblMessage.Text = response<br />
End Sub
Any help will be greatly appreciated!

hi,
can anybody Pls. guide me how can i disable the option of saving/copying images on its right click in asp.net webforms.
I need to perform this task in c#.net 2.0.
Thanks,

I would say .. "Don't do that! man" it is just wasting time and money..
There are a lot of people who has already tried to achieve this but there are always some sorts of hecks for copying images.
Let me tell you some attempts that people tried to protect their images of being copied
#1. Disabling right-click.
Everybody knows this is useless.. Don't forget "Save as" or "Firebug"
#2. Showing the transparent images over the actual image.
It can trick the normal user but not for advanced user. There are very powerful tool (eg: Firebug) that can manipulate the HTML DOM in very easy way.
#3. Using third-party tool for protecting images.
If you google a lit bit, you will see a lot of ads mentioning that they can protect yours images (even HTML code). I have tried them some time back. Those tools are NOT good enough.
#4. Embedded Object(Flash or ActiveX)
Using flash might be the best way (so far) for image protection. But one thing, there are some tools or firefox extension (eg: Download Helper ) that can easily download .flv (flash) file. so, peopele might not able to copy the image but they can still copy the *.flv file.
So, don't do that.. man... Of course, this is my own opinion. so, you may wanna listen what other people say.

Everything is working fine on my local machine. But when I deployed this Application on server and tried to download files I am receiving error "Access to the path 'MyServerpath\Applicationname\App_Data\Downloads\zipfilename.zip' is denied.
I am not using any particular accounts for user to access this functionality and is not having any groups also.
Here is my code: where i am getting error:(having //Error tag)
string filepath = (Server.MapPath("./App_Data/Downloads/") + zippedfile);
//Error System.IO.FileStream fs = new System.IO.FileStream(filepath, System.IO.FileMode.Open);

//Response.ContentType = "application/zip";
///set Content-Disposition
Response.AppendHeader("Content-Disposition", "attachment; filename=" + zippedfile);

Ask the server admin people (your ISP support?) to grant you WRITE access on this folder.

Its a simple 3 cell table layout:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><br />
<html style="height: 100%;"><br />
<head><br />
</head><br />
<body style="height: 100%; margin: 0px 0px 0px 0px;"><br />
<table height="100%" style="width: 100%; border: 5px solid #000000;"><br />
<tr><br />
<td colspan="2" width="100%"><br />
<div style="height: 60px;"><br />
top</div></td></tr><br />
<tr><br />
<td height="100%" style="border: 1px solid red;"><br />
<div style="width:250px;"><br />
left</div></td><br />
<td width="100%"><br />
cont</td></tr><br />
</table><br />
</body><br />
</html><br />
In firefox it shows up just as i wanted, but when i open it in IE7 the table is actually bigger than window size and the vertical scroll bar apears. When i resize window it sometimes shows correct, but most of the time not.
what am i doing wrong here?

When several users access my web application simultaneously, which hosts several webservices, fails for some reason.
My application is hosted in windows xp machine.Is there any maximum limit on inbound and outbound connection limit. Does OS comes into picture when webservice is accessed by several users simultaneously.
Does anyone has any idea why this kind of behavior occurs.

As far as I am aware, IIS under XP pro has the maximum number of simultaneous connections set to 10. This certainly used to be the case under 115 5 - wheterh it's changed since I don't know. Ages ago I came across this somewhere:
"XP Pro allows 10 connections. This limit is installed by default in the metabase key MaxConnections for W3SVC, and there is no user interface method for modifying the setting. You can change this setting to any number less than 40 and it works, but that is not widely advertised."
but how you set about changing this I never investigated - it still implies a max limit of 40 though.
Really, XP is only a development platform. For serious hosting you should install your app on a machine runnong one fo the Windows Server OS's...
You should really be asking this in the SysAdmin forum - you'd probably get a more informed answer!
