AJAX :: How To Debug WebMethod In Form Application
May 3, 2012
I have gone though  article [URL] ....
Sending and receiving json data.
There i have noticed you are debuging webmethod to get the properties of city object.
In my application i am making a ajax call to a webmethod and getting a error, Â in firebug it shows internal server error . I believe there must be some bug in my webmethod. But i dont know how to debug it setting break point in my code didn't work as it overlooks the break point.

I have an ASP.NET C# project consuming webservices and WebMethods are wrote in VB.NET with source code on a local IIS server. The WebMethod returns null, and I want to debug it to know why I get this.
if I set a breakpoint just before the webmethod call, I cant step into this webmethod.
So, how is the correct way to debug this webmethod?

I have a service that works great on my development box. It uses JQuery to hit my web service, and then the JSON results are sent back.
The web service is located on our basePage.cs. We didn't want to put out an external WebService for this. Our on beta box something different is happening.
The web page seems to be trying to call the web method correctly - the JSON data is being sent... but the server doesn't seem to know it's a webmethod. here's my service function (it's in our basepage.cs which inherits from Page).

Upon clicking a button I need to send a collection and a few other variables to server in Json form.For each value in the collection the server code (C# ) wil update those other variables in the DB.
For example there is a ‘classnumber’ collection with values (First, Second, Third, ….),other variables (‘teacher_name’ and ‘subjectname’).For each value in the ‘classnumber’ collection I need to update the ‘teacher_name’ by searching for the ‘subject_name’ in the DB.So I need to pass the ‘classnumber’ collection,’teacher_name’,’subject_name’ values to server in json form. At the moment instead of sending the ‘classnumber’ collection I am sending ‘teacher_name’,’subject_name’,’classnumber’ as variables for each value in the collection ,which requires multiple requests made to the server.
Instead of these individual requests I am wondering if there is a way to send all the data at once to server in json form?

I'm starting a new web site which involves a Novell/LDAP login to enter. Just installed VS2008, using framework 2.0, configured web.config to use authentication using form login.aspx which is the LDAP form we reuse from app to app. Debug is enabled, in form and in VS options. I'm running with localhost web server. Problem is debug doesn't work in the login form, does not stop at breakpoints I put in page_load event. Tried to bypass the login form to make sure, turns out debug will work on some startup form I made but does not when I redirect to login form. It seems VS2008 does not like something in my login form.

While adding the parameters to get/post request they need to be encoded in application/x-www-form-urlencoded form. So do we need to encode values each time ? Does JavaScript have any method for that ? What are the possible caches ?On server side when we read the values we do not decode them we directly say Request.Params["key"] and that returns value. Does that mean that they are automatically taken care when we read the values?

I have developed an application that interacts with IBM ClearQuest. The problem is that when I run everything locally, such as, run the webservice local and then ASP page local everything is at the speed I expect. When I post the webservice (precompiled) to the server and run the web page through the server, the call to the webmethod takes at least 10x the amount of time it should. I dont know why this is happening. I made a console application that has the function in question and execute it on the server and locally and they both return the same amounts of time (roughly) its just when I move to executing via the webmethod everything grinds to a snails pace. Any ideas? This happens every time not just on the first call.
WebMethod:
Public Function RetrieveQueryResults(ByRef cqSession As ClearQuestOleServer.Session, _

Dim colValue As New Object
Dim colLabel As New Object
Dim allitems As New List(Of SearchResultsSingleIssue)
Dim results As New SearchResultsSingleIssue
Dim cqResultSet As ClearQuestOleServer.OAdResultset
cqResultSet = cqSession.BuildSQLQuery(sqlStmt)
cqResultSet.Execute()

The message sent to browser is as follows:
The type My.API.Class is ambiguous: it could come from assembly '[on Temporary ASP.NET Files]' or from assembly '[on bin folder]'
The problem occurs when debugging a Web App, speciically when making a request to a WebMethod of a WebService.The project compiles just right. It generates My.Website.dll on bin folder and if I publish the Web Application. It works fine.The asmx file is on the root of the application. The CodeBehind file is on App_Code and its marked to be compiled to generate My.Website.dll.The way this person exposes its problem is somehow similar but I get starting to be lost when he talks about a proxy class and shared dlls I don't use.

HWhen I want to use AJAX, primarily with JQuery .ajax function, I use functions within the .aspx.cs of the same page with [WebMethod].
I dont like this method very much because everyone can tell which function I use, and with no problem they can use it too.
My guess is that theres a better way to do this, Am I right?

I am currently developing a silverlight application, however yesterday I started getting the following error message every time I run the project:
If I click "yes" to debug - nothing happens. Also, I have no Line 1805 in any of my source files!
This error message started appearing yesterday, and appears as soon as I run the project, shortly before the first page loads. If i click yes or no, the project then loads and runs perfectly, I cannot see any unwanted behaviour.
I have been using source control, so I rolled back the project to a point before the error started appearing, however I am still getting the error!
Could it be a setting in VS Web Developer Express 2010 that I have accidentally changed?

I'm working on an application (a web application, asp.net and c#) which is datetime-dependent, so, based on the current date, it will launch forms for the logged user to fill in.
I've been thinking about how we're going to simulate real usage of the application, for debugging and testing purposes.
So I'm talking about replacing all those:
DateTime currentDate = DateTime.Now;
with something like:
DateTime currentDate = MyDateClass.GetCurrentDate();
And then I'll have a class:
public class MyDateClass
{
private DateTime _currentDate;
public DateTime GetCurrentDate()
{
// get the date, which may be different from DateTime.Now
return _currentDate;
}
public void SetCurrentDate(DateTime newCurrentDate)
{
// set the date to the value chosen by the user
_currentDate = newCurrentDate;
}
}
allowing me to set the current data, by invoking the SetCurrentDate method, for example, in the code-behind of a link button and a calendar input.
how should I exactly store the DateTime variable, throughout all the application? I can't work with the session in this class, right? Should I work with the Thread?

I've defined a route in Application_Start, as so many tutorials have instructed
RouteTable.Routes.Add(
"Files",
new Route("Files/Art",
new FileRouteHandler()));
And created my own RouteHandler. However this doesn't seem to work at all.When I debug the application, I can see (via a break point) that the route gets added, however when I browse to "http://localhost/MyApplication/Files/Art" I get a browser 404 (not an ASP.net 404).

After an IISRESET on my public facing webserver, the initialization of my app seems correct. That is, in the Application_Start event I launch a new "email" thread whose purpose is to sleep until the configured time, upon "waking" produce a report and email it to my administrative user(s) and go back to sleep until the configured duration elapses at which time, the report is created again and emailed out. I am currently configured to start at 1900 and produce a new report every 12 hours.
As time marches on with this production site, however, something is causing an "extra" thread to be created. This, in turn, results in a duplicate report being emailed. While the problem is benign enough, I'd like to clean this up if possible. Here's a snippet:
[code]....
The above code seems to work fine (like I stated, after an IISRESET, I see the one logged event from the Application_Start event followed by the log entry from my "email" thread: "EmailThread will sleep for nnn minutes...etc.". But somehow (over time) I am getting another instance of the EmailThread thus producing 2 reports instead of just one at the scheduled "wake time".
In the IIS application pool assigned to this website, I have the following settings:
- Recycle worker processes (in minutes) is UNCHECKED
- Recycle worker process (number of requests) is UNCHECKED
- Recycle worker process (at various times) is UNCHECKED / nothing specified
- [Idle timeout] Shutdown worker process after being idle for (time in minutes) is UNCHECKED
I have noticed that the Application_Start event can be entered again (in one case roughly 38 minutes after the first time) which causes my code to run again and create another [and unwanted] thread.

The default ASP.NET web server that launches from within Visual Studio (Casini) is a little buggy on my development machine, so I like to publish to a local IIS instance on my dev machine and look at the web application there. However, I'm not automatically in "Debug Mode" when I launch the application this way.
I know that VS 2010 has an "Attach to Process" debug feature, but I'm not sure exactly how to use it. What do I need to do to be able to debug a local IIS ASP.NET web application from within Visual Studio? Specifically:
What settings do I need to change in the configuration of my web application?
What "Package/Publish Settings" do I need to change?
Is there anything I need to change in IIS?
Is there anything special I need to do in the "Attach to Process" screen?
Background Information: I'm running Visual Studio 2010 on Windows XP SP3 with IIS 5.1 and .NET 4.0.
Additional Information:
I should add that I've tried attaching to aspnet_wp.exe, but when I go to a page that I know has a breakpoint in it, I get the following message when I hover over the "open circle" breakpoint:
The breakpoint will not currently be hit. No symbols have been loaded for this document.

I know there have been countless posts on these types of problems, and I have read through alot of them as well as doing Google searches, but I have not found anything that applies to my specific situation. If anyone has posted a similar question link me to the post with any appropriate derisive comments . Mods if this is the wrong forum feel free to move the post to the appropriate location.
I am a newbie C# developer. I have been getting my feet wet writing a C# web app for my department. I am using the following system:
Windows 7 Professional Visual Web Developer 2010 Version 10.0.30319.1 .Net framework 4.0.30319. IIS version 7.5.7600.16385 Internet Explorer 8.0.7600.16385CO SQL Server 2008 R2
When I run my application in the VWD debugger everything works fine and looks the way I want it to work. When I deploy to IIS (which is on the same box that I develop on) I start having some issues. Here is a breakdown of the problems I am having:
I have an asp:menu control with orientation set to horizontal. When I initially load the sitre after a deploy the menu displays correctly. But when I go to a different web page in the app the menu switches to vertical and the width of each menu item spans the width of the div that surrounds it. On the same page that causes issues with the asp:menu I also have asp:ComboBox controls that are used to filter information on the page. The combo boxes just look like text boxes. The data that should populate the boxes is not present.
I also have some ajax accordion controls contained in asp:updatepanels, neither of which work. The accordion controls are all expanded, and I cannot collapse them. If I trigger an update the entire page reloads instead of just the specific control.
I do not receive any errors when I browse to the page that causes the problems. It loads just fine everything is just jacked up. Like I said, everything works flawlessly in the VWD debugger. I know the VWD debugger does not use IIS, which makes me think this is an IIS issue, but I do not even know where to start to pinpoint the problem.

I am having great issues trying to debug a page on a web application used internally on an intranet. When entering the page the "Security Information" Pop Up Box appears. The whole application is running under https.
To try and debug the issue, I have used Fiddler, and looked at the urls for every component, javascript, css, images, and user control components. Everything I have seen from Fiddler shows that the urls start with required https! So, I am completely confused why this message should be shown - it appears everything the page is posted back.
