.net - Using WebRequest.Create Inside RenderControl() For WebParts
Sep 20, 2010
I need to call a web service to receive a JSON object which I'll parse before rendering the content. Here's the code for the same:[code...]
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. I get the error "The "CustomWebPart" Web Part appears to be causing a problem. Request for the permission of type 'System.Net.WebPermission, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed."[code...]

I am writing some rest calls to the LinkedIn API using web request and have hit an encoding issue.The LinkedIn API takes requires an encoded URI as one of the parameters on the lookup i am trying to run.
We are calling the api through .Net's WebRequest.Create; and when we pass in the URI it decodes it and as a result we can't get the data from the call. Im trying to open a URI like this[URL]..Is there a mechanism in the webrequest class to stop it decoding the passed in URI; or a work around for this?

I borrowed part of this routine to download files, and it works great; except when I download text files the returns aren't written into the outputted file. I've tried different web request and techniques with no luck in solving the problem.
Test file:[URL]
Private Sub DownloadFile(ByRef FileSource As String, ByRef FileDestination As string)
Dim request As WebRequest
Dim response As WebResponse
[Code].....

I'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.

I create a new mdi child inside my mdi parent. do the work, save the data and close the form.Then I open the same form again, different record, and it opens up cascading as if the 1st form is still open. (even though it is closed)I've search the net for the past hour, and can find no concrete information regarding this issue.Now imagine sales department creating 100 sales orders a day. they keep on having the issue to move the form back to the top.

I have a class that add extra information about a column for linq2sql (see code below) right now, I have to explicitly tell what column I want that info on, how would you put that code with a loop on every column in every table from a dbml file? I was doing my test on a very very small DB, now I have to implement it on a much more bigger database and I really don't want to do it manually for every tables/columns it will take hours.
how it's being used:
Partial Class Contact ''contact is a table inside a dbml file.
Private _ContactIDColumn As ExtraColumnInfo
Private _ContactNameColumn As ExtraColumnInfo
Private _ContactEmailColumn As ExtraColumnInfo

I 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.

I dont know what i did wrong Here is the code:Im trying to login to uploadee btw, a paid per download site.
Dim Postdata As String = "sec_login=sec_user_in&email_two=" & TextBox1.Text & "%40hotmail.com" "&password_two="& TextBox2.Text & "&x=0&y=0"
Dim tempcookies As CookieContainer
[code].....
Variable 'encoding' is used before it has been assigned a value. A null reference exception could result at runtime.Variable 'tempcookies' is used before it has been assigned a value. A null reference exception could result at runtime.

I 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:

I 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?

I think this is a simple question for you, but I don't understand other cases of webRequests, so I asked here: How can I make this webRequest asynchronous?
Dim sBuffer As String
Dim oRequest As WebRequest = WebRequest.Create(url)
oRequest.Method = "GET"
Dim oResponse As WebResponse = oRequest.GetResponse()
Dim oStream As New StreamReader(oResponse.GetResponseStream())

The 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.
