I have a report that I generate with HTML.
I'd like to get the HTML output of the page, and be able to send it via email. I'm having problem with session, because the report redirect me to the login page because when I create a new WebRequest, it doesn't use the information of the current session.
Is there a way to get the HTML of the report without having to code a work-around for the security ?
I am currently working on a ASP.net web app which the user enters info into input boxes and selects items from dropdowns. Once the user is finished they click on a button which validates the fields (using jquery validate plugin) and then removes the fields and replaces them with only field value. So essentially there are no more input fields only text.
The next step is to click on a button which will convert the html to pdf. However, when I do this, the PDF that is generated has all of the input fields that I previously removed. When I debug, I notice the HTML being returned is still the old HTML and when I view the page source, I am still seeing the old HTML even though the browser is showing the changes.
I am using this to grab the current html after the button click:
string htmlCode;
WebClient wb =
new
WebClient();
htmlCode = wb.DownloadString(devurl);
Is it at all possible to inject a request into IIS for a page, have IIS and ASP.Net handle it as normal, but get the response as html handed back to me programmatically?
Yes, I know that I could connect to port 80 using WebRequest and WebResponse, but that becomes difficult if you are accessing the IIS server from the same physical machine (loopback security controls et al).
Basically, I want to inject the request (eg for [URL]) between the points at which IIS would normally talk to the browser, and the point at which it would route it to the correct ASP.Net application, and get a response back from IIS between the points at which ASP.Net/IIS applies the httpfilters and hands the html back to the browser.
I'm predominantly working with IIS7 so if there is a solution that works just for IIS7 then thats not an issue.
I am working on an ASP.NET MVC 2 project with VS 2010 and out of nothing I get the following errors on my views:

View 3 RepliesIs there no way to detect if the current request is being mapped via ASP.NET 4.0 URL routing?
I have an HTTP module that handles the application's BeginRequest event. I have found that this handler is called for all file types, including CSS, JS, image files, etc., and I just want to perform an action if the target file is an ASPX page.
In the case of routed pages, all the properties of the HttpRequest object reflect the requested URL, and not the ASPX page that the request is being mapped to. How can I determine if the request will be handled by an ASPX file?
Why does HttpContext.Current.Request.Url.Host return a different URL than the URL used in the Web browser? For example, when entering "www.someurl.com" in the browser, the HttpContext.Current.Request.Url.Host variable is equal to "www.someotherurl.com".
View 1 RepliesI've got an ASP .Net application running on IIS7. I'm using the current url that the site is running under to set some static properties on a class in my application. To do this, I'm getting the domain name using this (insde the class's static constructor):
var host = HttpContext.Current.Request.Url.Host;
And it works fine on my dev machine (windows XP / Cassini). However, when I deploy to IIS7, I get an exception: "Request is not available in this context".
I'm guessing this is because I'm using this code in the static constructor of an object, which is getting executed in IIS before any requests come in; and Cassini doesn't trigger the static constructor until a request happens. Now, I didn't originally like the idea of pulling the domain name from the Request for this very reason, but it was the only place I found it =)
So, does anyone know of another place that I can get the host domain name? I'm assuming that ASP .Net has got to be aware of it at some level independent of HttpRequests, I just don't know how to access it.

I have IIS on S2k8 and a website with Windows Authentication only.
I can easily reproduce the following scenario, where HttpContext.Current.Request.LogonUserIdentity.Name has a bad value:
Login to website using FireFox, using an Active Directory account "user" (I could use IE to reproduce the same, but it's a few extra steps)Display <%=System.Web.HttpContext.Current.Request.LogonUserIdentity.Name%> on the pageIt shows "DOMAINuser", which is correctI go into Active Directory and rename the account to be "userX" instead of "user" (both SAMAccountName & UPN)Restart FireFoxLogin to website using "userX" accountThe page still shows "DOMAINuser", instead of the expected "DOMAINuserX"
It seems almost as if IIS has cached the old username and it's not showing me the new one, even though I explicitly enter it in the login prompt.

In an asynchronous process, I need to get the name of the domain/server the web application is running on. But in that situation HttpContext.Current is not available, so I cant use HttpContext.Current.Request.ServerVariables("SERVER_NAME").
View 7 RepliesI have various web pages that need to build up a URL to display or place it in an emitted email message. The code I inherited had this value for the name of the webserver in a Public Const in a Public Class called FixedConstants. For example:
Public Const cdServerName As String = "WEBSERVERNAME"
Trying to improve on this, I wrote this:
Public Class UIFunction
Public Shared myhttpcontext As HttpContext
Public Shared Function cdWebServer() As String
Dim s As New StringBuilder("http://")
Dim h As String
h = String.Empty
Try
h = Current.Request.ServerVariables("REMOTE_HOST").ToString()
Catch ex As Exception
Dim m As String
m = ex.Message.ToString() 'Ignore this should-not-occur thingy
End Try
If h = String.Empty Then
h = "SomeWebServer"
End If
s.Append(h)
s.Append("/")
Return s.ToString()
End Function
I've tried different things while debugging such as HttpContext.Current.Request.UserHostName and I always get an empty string which pumps out my default string "SomeWebServer". I know Request.UserHostName or Request.ServerVariables("REMOTE_HOST") works when invoked from a page but why does this return empty when invoked from a called method of a class file (i.e. UIFunction.vb)?

I was/am struggling with security for my first MVC applicaiton. It worked out great for me, but not for my users. I wanted to use Windows Authentication (and I seem to have that working). But when I was still trying to implement it, I was on one of our users computers where they were logged in. I navigated to the main Index page and used the supplied MVC login link and *MY* credentials. So now every time that user navigates to that page, it logs her in as me. We are using IE8, I have deleted all the cookies, passwords, forms information I can fine through Tools|Internet Options|Tool|Content|AutoComplete.

a) In Asp.Net we can check whether a request is a postback or not via Page.IsPostBack property.But where does this property get its value from? Thus, where in the incoming request does browser put this value? b) As far as I can tell, hitting a reload button also causes browser to send form data back to the server. Thus, is under the hood hitting browser's reload button same as pressing a submit button ( which is nested within a FORM element)?c) Assuming browser displays A.aspx for the fist time and assuming user clicks browser's reload button, then I would think this request will be considered as a postback by Asp.Net (especially since browser also sends back any form data), but it's not.
View 1 RepliesFor many of the Ajax ControlToolkit, a post back causes a lot of screw up with these controls. One example is the MaskedEditExtender. I have a webform that has various parts which depends on a RadioButtonList control option. Some part of webform maybe hidden or shown base on what option the user chose from the RadioButtonList control. The RadioButtonList control is set to autopostback. Let's say there is the txtDate textbox that regardless what option the user chose from the RadiobuttonList control, it will always shown on the webform. Let's say the user type in 2/5/2010 on the txtDate control but later on decides to pick a different option in the RadioButtonList control. After the autopostback from the RadioButtonList control, the txtDate that contained 2/5/2010 is now wiped out or cleared. So, my question is, how do I prevent this from happening?
View 1 RepliesI'm implementing a custom page caching solution and I don't want the request to be cached or retrieved from the cache if it's in response to a form submission or some sort of asp.net postback.I'm trying to figure out if the current HttpRequest is a postback. Is there a way of doing this outside the context of a page or other usercontrol? In otherwords if I'm inside an HttpModule I don't have access to this.IsPostBack but I still need to determine if it is in fact a postback.
