Using VS2008sp1, I'm publishing Web app to a separate IIS7.5 server. It's been ok for a while, but hit this strange scenario:
-Created a class file that generates its own DLL.
-works fine locally
-When publish to server, the older DLL file is there along with all the other newer files (based on time stamp). The application dies when it tries to execute the new class method (it knows of the correct method call, but cant find the method. e.g method not found: class.method() )
-turned off IIS service. Deleted DLL file, republished: still showed older DLL (???)
Its obviously cached / protected somewhere, but how do I get around this an publish all as a group? Do I need to restart IIS everytime?
I have a webservice (ASP.NET) deployed on a webfarm. A client application consumes it on daily basis. The problem is that some of its calls are duplicated (with difference of milliseconds). For example I have a function Foo(string a,string b). The client app calls this webmethod as Foo('test1','test2') once but my log shows that it is being called twice or sometimes 3 or 4 times randomly. Is this anything wrong with the webfarm or the code? Note that the webmethod has simple straighfarward insert and update statements.
View 1 RepliesI am using asp.net 2005 with vb and developing MCQ program.
I am reading question information from a database and array . the array is "public shared" one. the problem is when two users are login to the system both are getting the same array.
my reqrement is give seperate instances for the diffrent users.
as an example the first user can open paper with 25 questions and second user can open paper with 10 questions. First it display no of questions as 25 and when then second user open the site, then the first site also display the total no of question as 10.
I tried to use variable declareing with DIM statement then they are unable to access from other events.
I have to update the users based on input value..
here is my code..
<fieldset>
<legend>StudnetInfo</legend>
here i have two textboxes and two dropdown list boxes.. this is the fiedlset user is going to enter their information..
</fieldset>
on the same page i have couple of other Fieldset with there studentInfo with twotextboxes and two dropdownlistboxes smililarly above Fieldset..this data dynamically generated from database for each users.
so all here my intension is insted of updating each and every Fieldset i made one generic fieldset to update all other Fieldsets information
on the Generic view I have this BeginForm
<% using (Html.BeginForm("Update", "home", FormMethod.Post,
new { @id="studentid"}))
{ %>
my JsonResult is
public JsonResult Update(StudentBE e)
{
try
{
var UStatus = Generic.UpdateStudent(e.student,"","");
return Json(UStatus.ToString());
}
catch (Exception ex)
{
return Json(ex.ToString());
}
finally
{
}
}
using this I can update only one user perfectly but I need to loo update all users based on generic Filedset values?
I'm using .Net 2008 and Oracle 10g as my database. The problem I'm getting is after deploying the application in IIS, when multiple users access the same page at a time i'm getting the error. Can't get the output.
Note: Both the users accessing the same page, same menu at a time.
How can I resolve this?
i am still relatively new to web development and have been encountering some issues when multiple users click a button at the same time.
i was wondering what could be causing this as i have already removed all static variables realiseing that was a mistake and replaced them with viewstates were needed then sessions when moving across pages

View 5 RepliesHaving an issue with the combobox overwriting the user input if there is a partial match.
[Code]....
If there is a record such as "NETEX" and the user types in "New Item", an item not in the data source, then the value is "NEw Item". If the user goes back to change the "E" to "e", it replaces the entire line with "NETEX".
Using CaseSensitive="true" is not an option as the user would have to capiltalize the beginning of every input to get hits, allowing for case-sensitive duplicates.
Have tried DropDownStyle="Simple" and all flavors of AutoCompleteMode to no success.
I wanted to know how to prevent more than one user from uploading the report at a time .
This is a Windos based app written in c# . When User A clicks Upload option on one server from the menu to upload the files and at the same time when User B clicks Upload option on different server , User B should be alerted a message saying "User A's uploading is in progress,pls wait" . How to achieve this, with the code..I am thinking this logic should be kept in a stored proc, How do I write that proc?

View 3 RepliesI am having an aspx page in which I am calling a user control. The user control I am using a pop up to display it when a user clicks a asp:linkbutton. In that user control I am having a textbox and I am calling a Jquery Blur to do some validation. While doing so the function is calling [blur] is calling twice. I just called an alert() with the textbox value.So I can see the alert is coming twice .What I need to do to avoid the second time. I need to do it only whenever the user going out of the textbox and that also one time.
$('#<%=txtCategory.ClientID %>').blur(function() {
alert($(this).val());
});
I've got a web app running with purely web services like these:
Code:
<WebMethod()> _
<ScriptMethod(ResponseFormat:=ResponseFormat.Json, UseHttpGet:=False)> _
Public Function EditService(ByVal toddtype As String _
, ByVal fromddtype As String _
[Code] ....
And I want to log each web service call. I don't want to bother my database with this log - I would prefer to have the web app log to a text file on the web server itself.
How would I open and access a log file like this from a bunch of web services? Does web app still have application startup like events???

Are there any transactions around multiple webservice calls.Let me start with a commonly used example -- the travel agency. A customer intends to create a travel plan through an online travel agency. To do this, the online travel application calls the following three Web services:
-Air ticket booking
-Hotel reservation
-Taxi reservation
These three services are available from three separate vendors. If any one of these three services fails, the customer does not wish to proceed with the transaction (again, either all three services must succeed or none at all).My language programming is Asp.net c#.
Are there any transactions around multiple webservice calls?but in ASP.net forum I got the answer below:
http://jalpesh.blogspot.com/2010/05/using-transactions-with-linq-to-sql.html it's offering system.transaction.
When I am updating a record with linq to sql my DeleteLesson() method is getting called multiple times.My controller looks like this :

EDIT.also if I use confirm = "Do you want to delete" in ajax options I will have to click okay three times.
We have a page that makes a request to a 3'rd party web service. When under heavy load this response time extends significantly, however the 3'rd party reports back that there times for processing remains constant. There timings show that from the time they receive a request to the time they send it back is always around 1.5-2.0 seconds. Now we are experiencing wait times of over 20 seconds. My understanding of ASP.NET is that each request will run on a IIS thread pool thread and make the request to the 3'rd party service return and process. So I don't really understand what could be blocking on our end. Is there something I am missing?? Is there a threshold limit beyond IIS that is blocking?
If I am missing something a physical book recommendation that covers this subject would also be a very welcome addition to any answer.
on my page I've to check if the UserName is available and sponsor code is correct. For that I'm using ajax call for both.

Login Name <span id="Login"></span><asp:TextBox ID="txtLoginName" runat="server" CssClass="DropText" onblur ="ShowLoginName()"></asp:TextBox>

Why they are not giving separate results?
I'm writing some merge functionality in C# asp.NET MVC2. I am also using using Linq2SQL.
I have a block of code which calls two services, MessageService and UserService. These both in term call their appropriate repositories and make the amendments to the db. Each repository declares it's own instance of the repository so I'm thinking this will escalate the following code to DTC . The code is called from the AccountService, is this going to work at this level? And also is it bad practise to declare the DataContext at the top of every repository or should I pass the object around somehow?
//Run the merge

{
using (TransactionScope scope = new TransactionScope()) [code]....
I have an existing asp.net web application I am redesigning to use a service architecture. I have the beginnings of an WCF service which I am able to call and perform functions with no problems. As far as updating data, it all makes sense. For example, I have a button that says Submit Order, it sends the data to the service, which does the processing.
Here's my concern: If I have an ASP.NET page that shows me a list of orders (View Orders page), and at the top I have a bunch of drop down lists for order types, and other search criteria which is populated by querying different tables from the database (lookup tables, etc). I am hoping to eventually completely decouple the web application from the DB, and use data contracts to pass information between the BLL, the SOA, and the web app. With that said, how can I reduce the # of WCF calls needed to load my "View Orders" page? I would need to make 1 call get the list of orders, and 1 call for each drop down list, etc because those are populated by individual functions in my BLL.
Is it good architecture to create a web service method that returns back a specialized data contract that consists of everything you would need to display a View Orders page, in 1 shot? Something like this pseudocode:
public class ViewOrderPageDTO
{
public OrderDTO[] Orders { get; set; }[code].....
Or is it better practice in the page_load event to make 5 or 6 or even 15 individual calls to the SOA to get the data needed to load the page? Therefore, bypassing the need for specialized wcf methods or DTO's that conglomerate other DTO?
