Web Forms :: How And Where To Use The Httplistener
Sep 5, 2010
I'm having some problems using the httplistener. Basically what I want to do is have my localhost running on [URL]. Under default.aspx.cs I want a listener waiting for the page to get a request. The webpage is then called by for example a console application doing a request to [URL] The problem I'm expering is that I have this code on the localhost running in page load for the page. I realize now that this will just keep my localhost waiting for a reply
[Code]....
This code is run from a console application
[Code]....
Then when I run my console application with this code, I get an error indication the connection had to be forcibly closed. What I'm guessing is that the IIS collides with the listener. Im wondering how and where do I set up a httplistener in a web page?? Is a httplistener neccesary for IIS, or is httplistener used instead of a IIS?? I can't change any port because localhost can only use one at a time? I cant use requeststring because the amount of data I need to send surpass the limit of requeststring.

I am instructed to use an HttpListener. A Service will call my URL, for example: [URL] My question is this. What kind of file do I use for a listener. Is it an .aspx file together with its .cs file as usual? If that is the case, I am told to retreive a string in this function below. I wonder how I will set this up in this function below correctly in order for "listen" for this String. I need to see that ipnValid == true. Do I do this in the Page_Load in any way etc.. ? (I beleive the String that is listening for is parsed with request.Form.Keys)
[Code]....

I have to establish an HttpListener that will wait for requests made by our client's server. I have to receive that request on port 8088 and extract the query string. That is the easy part. I'm running the HttpListener in a windows service. I cannot get it to fire properly. I build the setup project install the service on our server and it never starts. I suspect there's an error with my code.
HttpListenerClass:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
using System.Net;
using System.Threading;
namespace lalalolo
{
class HttpListenerClass
{
bool keepAlive = true;
public void AddToFile(string contents)
{
var fs = new FileStream(@"C:HttpListenerserv.txt", FileMode.OpenOrCreate, FileAccess.Write);
var sw = new StreamWriter(fs);
sw.BaseStream.Seek(0, SeekOrigin.End);
sw.WriteLine(contents);
sw.Flush();
sw.Close();
}
private HttpListener listener;
public HttpListenerClass()
{
ThreadPool.SetMaxThreads(50, 100);
ThreadPool.SetMinThreads(50, 50);
listener = new HttpListener();
listener.Prefixes.Add("http://*:8088/");
}
public void Start()
{
listener.Start();
if(keepalive == true){
{
try
{
HttpListenerContext ctx = listener.GetContext();
ThreadPool.QueueUserWorkItem(new WaitCallback(ProcessRequest), ctx);
}
catch(Exception ex)
{
AddToFile(ex.Message);
}
}
}
}
public void Stop()
{
listener.Stop();
keepalive == false;
}
public void ProcessRequest(object listenerContext)
{
try
{
var context = (HttpListenerContext)listenerContext;
string QS = context.Request.QueryString["ID"];
AddToFile(QS);
}
catch(Exception ex)
{
AddToFile(ex.Message);
}
}
}
}

In a Windows Service I implemented an HttpListener that will handle incoming HTTP Requests to a certain port, parse the query string, insert it in database and send a confirmation response. However, the clients said that they were a bit skeptical and asked if the same could have been done via a webpage. Like having an HTTPHandler listen to a certain port. Got me thinking. What would you do in my situation? Go with the HttpListener/Windows Service or HTTPHandler/.aspx?

In our application we are using forms authentication, we have given defaulturl also in the config file. But the problem is that it is not getting redirected to the default url when the session timeout is occuring.

I have been presented with numerous word and excel docs. The goal is to put them online and bind to a database for the fields and also to store data for easy searching and reporting.
Has anyone done anything like this before?
I know the easy solution would be to create a database table for each particula form and also an ASP.net page for each form.
But then there are problems like printing and correct formating so it fits on the page, spaning multiple pages and so on.
And also is there any advice on how to write to PDF straight from the page?

I have a treeview named Treeview1 with checkboxes. I want the child checkboxes to be checked if parent is checked.
I am trying to use a simple code that I found on msdn :
[Code]....
For some reasons I got this error and I really dont understand why:
Type 'System.Windows.Forms.TreeViewEventArgs' is not defined.
warning BC40056: Namespace or type specified in the Imports 'System.Windows.Forms' doesn't contain any public member or cannot be found. Make sure the namespace or the type is defined and contains at least one public member. Make sure the imported element name doesn't use any aliases.

Really getting better with VS, but I've mostly been displaying data. I'm on a new project and now and I have a lot of data entry forms to create. I created a form to enter data into an access db and got it working. I thought it would be cool to add an edit button that fired a gridview to load on the same page, under my original forms, so that that they could load up the data and edit or delete mistakes. But when I try to update the gridview, it also tries to post the original forms (text boxes), which fail because there is no data in them, and I get an error.
What is the proper way to handle this in asp.net? I'm sure this is kind of a common issue. I've done some searching, but the search terms, like forms and gridview, are kind of generic and I'm not coming up with anything useful. I just need a more experienced person to point me in the right direction and I'll get it figured out.

I am using forms authentication, and for some reason it shuts off my images. I have tried putting them in the same directoy, and still nothing.
If I turn off forms authentication, they come back alive so I know my urls are correct.

In windows forms, there is the "show data sources" under the "data" menu item, and I love it because I can drag and drop the fields I need onto the form and it makes the control automatically.In web forms however, this option isn't there. Why? I try to drag and drop fields from the "server explorer" but it generates grids, I don't want grids I just want to drag and drop the text boxes or checkboxes etc.

Created in VS2008
The login page is created with the masterpage and it has the header picture.
After Logout or run FormsAuthentication.SignOut();
The login page is not showing correctly with the header (from master page).
And the setting on the web.config as below:
<authentication mode="Forms">
<forms loginUrl="Login.aspx" name=".ASPXFORMSAUTH">
</forms>
</authentication>
<authorization>
<deny users="?" />
</authorization>
Is there any reason why the header from masterpage can not be viewed from the login page?

Form1 is for the administrator. It has 5 fields. Field1 has a value for which the other values give details about it. This 5 fields are stored in a table. Form2 is for a user and its a data entry form. This forms has 12 fields. Each label in the form2 corresponds to the value of Field1 in form1. If suppose the admin fields 10 times the form1. The 10 labels of form2 are filled with values of field each time. The above is what I want to achieve. Also the two text box corresponding to the remaining two labels should be disabled for user.

I'm building a web page that is going to make extensive use of User Controls. Using "LoadControl" it will have one of about 20 different User Controls loaded at any one time. Each User Control is somewhat different, gathering different sorts of data.
I've already built the mechanism to load the User Control and pass strongly typed data to it. But now I'm tackling the part of returning the user data to the Parent Form. I can think of several possible approaches to take but wanted to reach out to the community to learn what the best practice for doing this is.

A requirement of a program I am making is that it can 'print' a given URL into a PDF - the server has a PDF printer installed (and is the default printer), so it's just a matter of printing the page programmaticly, and it seems the best way is to use the WebBrowser control - however, I am running into issues
[Code]....
With the above code, I get a script error 'dialogArguments.___IE_PrintType' is null or not an object' in shdoclc.dll/preview.dlg. If I have wb.Print() to somethign like wb.ShowSaveDialog() (or something like that, can't remember exactly), I notice the 'wb' object's document is a blank page, with just <html> tags and named 'about:blank'. But strangely, almost identical code (without the threading bit in the page_load method) works perfect in a normal Winforms based application.
