Hi,
without viewing at your code, it is difficult to decide where the problem is. I'm doing the same
thing with itextsharp and a mysql db in some project. Here is how i basically do it:
Document myDocument = new Document(PageSize.A4);
MemoryStream mstream = new MemoryStream();
PdfWriter.GetInstance(myDocument, mstream );
myDocument.Open();
myDocument.Close();
byte[] fileData = mstream.GetBuffer();
As you're posting this in the asp.net forum, i suppose you want to write this pdf to your reponse stream? (or to file?!)
This is how i write it to response-stream in page-load of a download page
(you have to replace mimeType, fileName, fileSize and fileData by your own variables/strings - with
fileData being the byte[] and filesize the length of that byte[]):
Response.ClearHeaders();
Response.ClearContent();
Response.ContentType = mimeType;
Response.AppendHeader("content-disposition", "attachment; filename=" +
HttpUtility.UrlEncode(fileName, System.Text.Encoding.UTF8));
Response.AppendHeader("content-length", fileSize.ToString());
Response.BinaryWrite(fileData);
Response.End();
Hope this helps. If you've problems writing/reading this data from/to a file, let me know.

I have an ASP.NET 1.1 web application that I'm required to migrate from an IIS 6 environment (Windows Server 2003) to an IIS 7 environment (Windows Server 2008).
I'm experiencing problems with the DHTML menus. In IIS 6 they display the text and the link whereas in IIS 7 it only displays the text, not the link.
Is there a patch that I need to install on Windows Server 2008 to rectify this problem? What am I missing?
The menus display when I view the site in Mozilla (however, the menus don't work 100%), but not IE8
Has anyone else experienced this problem?
I am most confuzzled!!

hey
I tried to use smtp server to send email using C#.net.
But it is giving error on client.Send(message);
it says:
A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.
So Is that problem in my code or is this the problem from the server. How to fix this ?
Thanks

At what point can you determine when a web service connection has failed? As near as I can tell, you actually have to try calling a method in the service. Is that correct?

ya that's right
you need to call method to confirm it is getting connected..
For asp.net when you bind service reference
it will tell you by intellisense (at the time of
creating object or calling static method)
that whether you are connected to web service or not.

Hi people,
I want to track what IP's/MAC addresses connect to my web application - but I am having troubles getting the IP of the connecting client.
Every variable or method I try - I seem to end up getting the IP of the server or of the internet provider of the client computer!
Has anyone come across this problem before and come up with a definite solution? I have tried many alternatives that I found via google - but none seem to work 
Any help would be MUCH appreciated!
Thanks in advance.

There is no solution. The last step is a router which implements NAT, and forms the separation between the private address space (typically 192.168/16), and the internet. No IP information will cross that barrier.
If you're thinking of getting MAC addresses, it's even worse: the only address you'll ever see is the one of YOUR router. MAC addresses are a layer 2 thing (Media Access Control Layer), and routers operate on Layer 3 (Internet Layer) No Layer 2 information will ever cross a router.

I have install sucessfully AJAX Extesion & Ajax ControlToolKit for ASP.NET 2.0; AjaxControlToolKit is instaled by proper way(D:\web_prg\ControlToolKit2.0\SampleWebSite\Bin\AjaxControlToolKit.dll) that is provided with the SetUp(.exe) for AjaxControlKit.

you have to register the assembly in the header like
<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="asp" %>
Check the Assembly and Namespace according to your application
|
|
|
|
|
I have already register this Assembly in Header.
<%@ Control Language="C#" AutoEventWireup="true" CodeFile="MultipleSelection.ascx.cs" Inherits="MultipleSelection" %>
<%@ Register Assembly="CheckBoxListExCtrl" Namespace="CheckBoxListExCtrl" TagPrefix="cc1" %>
<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="cc2" %

Refresh the Ajax control Toolbox. and add the AjaxControlToolkit.dll again.

<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>

Probably all that stuff we call html and server control tags, like textbox and button.

I thought he was talking about the asp.net login control. 
|
|
|
|

So what issues/problems are you having? IMO login should not be done via ajax. The initial page should display only publicly accessible information, after authentication the user should be redirected to secured content.
