Web Forms :: Doesn't Seem To Processed Simultaneously?
Mar 5, 2010
I am using HTTP load testing tool to stress test my asp.net 2.0 application. I faced problem that, when I have 1 user access to the system (currently only test on login.aspx), it is very fast ~ 1-2 secs. However, when I run with 10 virtual users at the same time, it takes 10-12 secs for each.
User Response Time (s)
1 10.12
2 10.22
3 11.00
...
10 12.78
My question is, why ALL of them also takes 10-12 secs? Is it normal? I was thinking that should be some users take 2-3 secs and some 5-6 secs and etc.
I have a requirement where I want to trace what file is being processed by .net runtime. I mean if it is processing usercontrol x.ascx then it should return the whole path of that, and if it is processing usercontrol y.ascx it should return that. There are some candidates properties. equest.AppRelativeCurrentExecutionFilePathor TemplateControl.AppRelativeVirtualPath. Can somebody help me with this, or is there any other property that can give me the path.
Let's imaging there are 2 pages on the web site: quick and slow. Requests to slow page are executed for a 1 minute, request to quick 5 seconds.Whole my development career I thought that if 1st started request is slow: he will do a (synchronous) call to DB... wait answer... If during this time request to quick page will be done, this request will be processed while system is waiting for response from DB.[URL] One instance of the HttpApplication class is used to process many requests in its lifetime. However, it can process only one request at a time. Thus, member variables can be used to store per-request data.Does it mean that my original thoughts are wrong?Could you please clarify what they mean? I am pretty sure that thing are as I expect...
I have a page (i.e. page1.aspx) that a user will select from the record and it will press on the delete button. And it will redirect on another page (i.e. page2.aspx). On page2.aspx, I wrote my query for example
Code: DELETE FROM items WHERE item_id=2 how may I know if the query was successfully processed because I have to redirect again on the first page.
I have a page that has a bunch of user controls. I would like to be able to see which user controls are performing badly. I would like to be able to see this in the trace. any way to do this.
both site1 an site2 are using form authentication and creating the token further adding in cookie as below,
FormsAuthentication.Initialize(); FormsAuthenticationTicket ticket = new FormsAuthenticationTicket(1,username,DateTime.Now, DateTime.Now.AddMinutes(20),rememberMeSet,globalID ,FormsAuthentication.FormsCookiePath);
// Encrypt the ticket. String hash = FormsAuthentication.Encrypt(ticket); //Create the authentication cookie HttpCookie cookie = new HttpCookie(FormsAuthentication.FormsCookieName, hash);
My problem is when I'm logging in to Both site1 and site2 then these two are not running simultaneously on single browser using different tab for same user name.one is being logged out when logging to the other application and vice verse.
in fact I have 2 webservice calls, one returns 8 results and the other one 4 results. So the same webservice is called twice but with different arguments and on different pages(browsers).What happens? even though I call on one page only one webservice(arguments1), I also get the results from webservicearguments2) which should be only on PAGE2to be more clear: I get both webservice results in both the pages, when I expect one for each page, it's like they share webservice results somehow,
I fill a third-pard component variable in Global.Application_BeginRequest(). Everything is fine until I set IIS7 into the Integrated mode. In that case the method Application_BeginRequest() is not called (Application_Start is ok).May be some module is registered wrong?(I have found a same problem here on forum, but without a solution:[URL]
I have a aspx.cs page that renders a pdf file directly.
To render the pdf directly i have to use ContentType="applicationpdf" in my .aspx page.
The problem I am facing now is:
I need a time-request field - namely, the user would have to enter the time (from and to) and hit Go and the pdf will be rendered according to the date-requested.
However, I cannot display the time-request (or page option) field and render the pdf simultaneously.
I would like to display the following information for each "Camera" (in the format below) on my web page in an HTML table. All the data is contained in one table in my database:
For Camera = Canon (e.g.):
Type (Text via asp:Label) Lens Size (Text via asp:Label) Storage (Text via asp:Label) Max. video resolution (Text via asp:Label) Max. photo resolution (Text via asp:Label) Weight (Text via asp:Label) Dimensions (Text via asp:Label) Sensor (Text via asp:Label)
...where (Text) is the value retrieved from the database for the given Camera. advise on the best way to retrieve this data? The only method I can think of (from my limited experience!) is to have a separate VB function for each value, to run separate SELECT queries for each field, and then to set the (Text via asp:Label)
value accordingly. I am already doing this for datagrid retrieves etc. For example:[Code]....
BUT... I know there must be a better method for the above requirement!
I have placed Chekc box in Gridview when i select the check box can perform 2 operations simultaniously one is entire recordset is populated into form fileds and second one is can delete the selected record permanently from database table.following code for this fuctionality.
I am trying to reproduce a threading error condition within an HTTP Handler.
Basically, the ASP.net worker procecss is creating 2 threads which invoke the HTTP handler in my application simultaneously when a certain page loads.
Inside the http handler, is a resource which is not thread safe. Hence, when the 2 threads try to access it simultaneously an exception occurs.
I could potentially, put a lock statement around the resource, however I want to make sure that it is infact the case. So I wanted to create the situation in a console application first.
But i cant get 2 threads to execute a method at the same time like asp.net wp does. So, my question is how can you can create 2 threads which can execute a method at the same time.
Edit:
The underlying resource is a sql database with a user table (has a name column only). Here is a sample code i tried.
[TestClass] public class UnitTest1 { [TestMethod] public void Linq2SqlThreadSafetyTest()
I have two ASP.NET AJAX UpdatePanels . there are two timers with diffrent intervals. is it possible to update two updatepanels simultaneously together ? like multi thread application . each should be UpdatePanel Update in separate thread in one time. i wrote this code but second timer does not work :
<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent"> <h2> Welcome to ASP.NET! </h2> <p>
i am doin my final year project and in my project i want to watermark multiple images simultaneously where image,logo,position,alpha and key value is stored in a database table ....i need to retreive these details from db table and perform watermark on those images....
I have Asp:TextBox,Asp:RegularExpressionValidator and Asp:RangeValidator on .aspx page.
These two validators have ControlToValidate value equal to textBox Id.
RegularExpressionValidator have validation Expression such that it allows only number.
Range validator have maximum value ="100" and if I enter any text then both validators get fired .
Logically only RegularExpressionValidator should fire if I enter any textvalue.
Is there any property of Range validator such that it check for numeric value to compare and disbled if value entered in textBox is some text so that no handling of event(Client side and Server side both) is required.
I have an update panel in my ASP.NET web form with a trigger that will fire a click event when the contents within my update panel is updated (it's a grid view with fields). The event that is fired when then take the changes user made and do some calculation and then update another update panel with that information. This is all fine and dandy when the user tabs along the form and fill out the form in a orderly fashion before hitting any buttons on the page.
If a user accidentally hits another button on the page while changing the content in my grid within the update panel, for example, the user enter a value in my grid view control, without tabbing, the user click the save button. Logically, i believe that the trigger should fire the click event first (event A), and then the save button event (event B). But, consistently I haven't seen event A gets fire correctly while event B gets fire all the time. is there a way to ensure event A always gets fired before event B? also if event A update another update panel without the page will event B fire after the update is complete?
I have two ajax time for my aspx web page but while the one is ticking , the other stops running. How can i make it both timer run together like the windows form?
I have a page in which there are multiple updatepanels and each of these update panels are trigerred by different triggers.
These update panels are used to do Async post back and the page is updated with the data retrieved from the async post back.
Now the issue i am facing is that since there are multiple update panels, the update done by one panel is lost when the other panels does the post back.
let me know if any one knows on how to solve this issue.
I have recently combined my aspnet membership database and main website database into one database file, I'm happy with the schemas, stored procedures etc. (This is a development project not yet a production project.)
My problem is that I can no longer simultaneously connect to the database from Visual Studio if a user is logged in to the website.
EG:
Scenario 1: No user is logged in to the website. I can go to the Data Connection window in VS, choose "Add Connection" and then inspect the contents and schemas of the database. This is fine.
Scenario 2: A user is logged in on the website. I try to connect to the website in VS and get the error:
"Cannot open user default database. Login failed. "
Scenario 3: I am connected to the database in VS and nobody is logged into the website. If someone tries to log into the website they get the following error:
Cannot open user default database. Login failed.
Login failed for user 'NT AUTHORITYNETWORK SERVICE'.
So it seems from the above that there can be only one connection to the database at a time? However this was not the case before I combined the membership database with the main website database. I could always make changes as a user logged into the website and at the same time see those changes through the connection in Visual Studio.
