Stop .Net HttpWebRequest.GetResponse() Raising An Exception?
Apr 23, 2010
configure the .Net HttpWebRequest object so that it does not raise an exception when HttpWebRequest.GetResponse() is called and any 300 or 400 status codes are returned?
Jon Skeet does not think so, so I almost dare not even ask, but I find it hard to believe there is no way around this. 300 and 400 response codes are valid responses in certain circumstances. Why would we be always forced to incur the overhead of an exception?
Perhaps there is some obscure configuration setting that evaded Jon Skeet? Perhaps there is a completely different type of request object that can be used that does not have this behavior?
(and yes, I know you can just catch the exception and get the response from that, but I would like to find a way not to have to).
End TryWhen I run the application in debug mode, the Response.Redirect statement raises an exception. When I have breakpoint to find out the Ex.Message, it says "Expression cannot be evaluated at this time."
I have a heavy traffic aspx page calling a web service upon every user`s request as follows.
string uri = "Path.asmx"; string soap = "soap xml string"; HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri); request.Headers.Add("SOAPAction", ""http://xxxxxx""); request.ContentType = "text/xml;charset="utf-8""; request.Accept = "text/xml"; request.Method = "POST"; using (Stream stm = request.GetRequestStream()) { using (StreamWriter stmw = new StreamWriter(stm)) { stmw.Write(soap); } } WebResponse response = request.GetResponse(); response.close();
Everything is working fine but sometimes I am getting the following error. The remote server returned an error: (500) Internal Server Error. at System.Net.HttpWebRequest.GetResponse() Does anybody have any idea about this error or can anybody tell me if I am doing wrong.
When I work with the tab Ajax control, and in one tab, I have a Repeater: <asp:Repeater runat="server" ID="rp1" onitemcommand="rp1_ItemCommand"> and in protected void rp1_ItemCommand(object source, RepeaterCommandEventArgs e) method, I add a button and it's event:
I'm using an AjaxToolKit Accordion Control and when I put a button in, the "onclick" event is not raising. When I use a dropDownList, if I select "autoPostBack", the event raises normaly (instead, nothing occours). But with buttons I cannot define the "autoPostBack" (its implicit?).
I have 2 web user controls, both inherit the same base class which extends UserControl. I want to raise an event on one and the other should be aware of it. both are on the same page however the 2nd control never handles the custom event i raised on the 1st one !
i'm trying to learn about user controls. I created a user control that has a textbox and a button. What i'd like to be able to do is when i click the button in the user control, populate a label in the aspx page. I understand that i could just have a button on the page that uses some properties on the user control to get that information.. but i'd like to know how to do it with the button the user control.. the reason for this is the button is just an example.. a learning tool. if i can get this working, i'd likely be putting thing in the user control that might require this kind of passing information. Anyway.. i've found some c# examples that i tried to get working as vb.. but once started getting into the delegates and events.. well.. it made me turn to this post.
I use SqlWebEventProvider to log the exceptions to sql server, and it works fine.
I also want to log custom exceptions to aspnet_WebEvent_Events table programmatically. Similar to - [URL]
WebBaseEvent.Raise(new WebErrorEvent("My Error message", null, 5000, e)); I get an error saying "Cannot access constructor 'WebErrorEvent' here due its protection level.
I have a list of events that have been retrieved from a database a bit like this: Easter St Patrick's Day Christmas Independence Day ... I would like to make them links and when you click on the link it raises a modal popup and displays a bit more information from the database about the event. So far, I've set up the ModalPopupExtender like this on my page:
[Code]....
I thought the links might look something like this:
I'm not quite sure how well this will repeat though. It looks like I'll have to have a ModalPopupExtender for every single link which doesn't sound very efficient. Am I doing this right?
i have the following problam:i have a user control which i want to raise an event from to the page that is using that user control (its a button)anyway my problem started when i wanted to put this user control inside a repeater instead of another button (regular asp:button) anyway i needed to support CommandArgument so that page can use the buttonso i created a property:
Private m_CommandArgument As Object Public Property CommandArgument() As Object Get
I am working on a 3-tier asp.net application. Currently I'm stuck up in a situation where I need to handle a specific type of exception (User Defined) in DAL and Show alert to the user if that exception occurs in DAL.
I tried following things:
1) I raised that exception from the DAL and catch it in BLL and throw a new BLL exception to for that DAL exception and finally catch it in the UI layer to show the alert to the user. I've successfully implement this in my project. But there are some issues in this approach. First of all I feel this is not right way to do this as it may lead to performance related issues. Secondly, the application contains more than 500 pages and classes. so I need to attach additional catch block in every method to catch the BLL exception. which is the last option i'd like to take.
2) in second approach I logged the the DAL exception into a text file. but problem in this approach is that how could the UI layer know that exception has occurred and show the alert to the user. Is there any event in asp.net where i could handle all this activities?
my question is what is the best approach to handle this type of situation? Will Exception handling block help me in this?
I've tried reading many articles on this but i couldn't get an answer for my question? I might not be using right keywords for my search.
In ASP.NET,How can i know the Specific details about an exception (like What kind of Exception it is (FileNotFound /Arithmentc etc..) )from a General Exception class object.
3. Data Access Layer to do the dealing with the database.
Now i have a Contacts page from where i can add a new contact to the database.So to add a New Contact i fill in all the required details and then call a Add Method (residing in the BLL) from the page, which in turn call a Add Method residing in the DAL.this method in the DAL returns the Current Identity of the record which is then return back to the BLL method and finally delivered on the page.this is fine. but what if a get an exception how do i handle it properly because the method in DAL has a return type of int and i dont want to throw another error!! coz other wise i will have to write try catch in almost all the methods.
//something like this public int AddMethod(ContactClass contactObj) { int result = 0;[code]...
rather i want to show the user a user-friendly message which they can easily understand and in the mean while i will send a mail to myself documenting the Error that just occurred.how can i implement my custom exception classes.
I'm trying to do some simple stuff, I've already looked at the examples through the web and I'm not sure of what I'm doing wrong It's a unit test that i'm doing to test some functionality that later will be performed by some different devices Basically I'm creating a webrequest to my site, which returns a set of cookies, which we later on need. Then I want to create a new webrequest, using the returned cookies from the first response, but when i'm reading that info, the cookies are empty
var request = (HttpWebRequest)WebRequest.Create("http://localhost/bla"); request.ContentType = "application/x-www-form-urlencoded"; request.Method = "GET"; request.CookieContainer = new CookieContainer(); request.CookieContainer.Add(originalResponse.Cookies); // originalResponse.Cookies has several cookies needed by "bla" var response = request.GetResponse(); In another place... (inside "bla") HttpContext.Current.Request.Cookies // this is empty
I am attempting to create a single sign on experience between an asp.net site and a wordpress site using a simple form POST method. I have built a simple php page that uses the native wordpress functions wp_insert_user and wp_signon to create user account in the mysql db and sign them in. In my asp.net 'create new user' page code behind, I'm using the post method of an HttpWebRequest to send the required information to the php page.
It almost works! The new wordpress user is created in the mysql database, but they are not logged in. How can I get wordpress to log them in?Here is my HttpWebRequest
'get the values Dim fn As String = TxtFirstName.Text Dim ln As String = TxtLastName.Text[code].....
Is there any way to uniquely identify a particular exception from the general exception class.
i.e any property or method that retrieves a unique identifier that to identify a particular exception.
I have kept some error values and corresponding error texts in an xml file. I want to read that xml file and have to taken the error ids and fix the corresponding texts to a label. in the case of a system exception we have to identify a particular exception.
