This works as a stand alone ASP.Net page. However, I need this as a Web Part to port to a Sharepoint site. Using the method described here I've given the above code in the RenderControl() method.

Request for the permission of type 'System.Net.WebPermission, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed."[code...]

View 3 RepliesCreate A DLL File With The Other One Inside?
Oct 14, 2009I'm creating a DLL file that has a reference to another DLL file.Is it possible to create a DLL file with the other one inside (thus not referring to another DLL file somewhere outside, but referring to itself).Eg: I've a.dll referring to b.dll.I want to include b inside a, hence having one dll file instead of 2.I know this is not the purpose of dynamic link libraries, but my libraries are about 15kb and with not page fault so often. So it doesn't really matter.

Aug 4, 2009I have a series of WebRequests in my app all formatted like this
Try
request.Timeout = 30000
' Get the response and read it to the end [HTML of a page]
[Code]....
After roughly 250 iterations of about 5-6 WebRequest per iteration, the app hangs and starts hitting the WebException "The remote name could not be resolved: 'hostnamehere' ". WebPages also don't load through my browser when this happens, I have to close the app for my internet to work again. This app is multithreaded and I was testing with 100 threads (in a threadpool, MaxThreadCount set to 20, addressof the sub which performs the WebRequests). A test with 20 threads yielded identical results - Same WebException also right around 250 iterations processing the same sub. I have tried setting the ConnectionLimit of the request to the thread count with no luck.

GET Webrequest Not Returning All Pages
Jul 19, 2010I am trying to implement the webrequest get and post methods. I am accessing a secure site that requires login authentication and was told that instead of sending a login request all the time; login to the site and capture the cookie and use this to send it in the header to get results from the page. In other words let us use google for example.
Lets say google required u to login before searching for something. Now I login through my browser and leave the site logged in. Now I send a httwebrequest from my program that includes the cookie authentication details in the request header and get results for say ?param=sports. Now when I increment the page number like &page=3, I am still only getting page 1 results. Here is some code:

Getting And Posting With Webrequest And Webresponse
Apr 3, 2010I would like to search an online (internet) database and import the result in my own Windows program. As I understand from reading and searching I first have to do a get from the default (search) page to get the cookies for instance and then do a post providing the filled input fields and adding the previously collected cookies. So far getting the information seems to work but submitting the data back to get the actual search result doesn't seem to work. This is what I have so far: [code]Anybody that can point me in the right direction? I my assumption correct that I first have to do a Get and then Post the correct data back?

View 1 RepliesVS 2010 WebRequest And Timeouts
Apr 20, 2011The current version of my application was using the WebClient object to download files from the internet and all was working well until some users reported that they were getting server timeouts. I looked into this issue and decided to move to the WebRequest object as it allows me to specify a Timeout value. The problem is, when using it synchronously, if I specify a timeout value of -1, I am worried that in the event of some weird server anamoly, my application would hang as it would be waiting for a response that isn't coming. So then I thought of using the WebRequest ansynchronously.
