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 made one window base application in VS2008 (VB.net). i made one simple code where i can insert data.and after inserting i can see that data on grid.when i am inserting data insert query runs perfect.after that for debugging purpose i fire select query and get result in dataset and its show data too.but when go
into database my inserted data not showing there.

Dim con As SqlConnection = New SqlConnection(con_str)
Dim cmd, cmd2 As SqlCommand

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.
View 1 RepliesLet'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...
View 2 RepliesI 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 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.
View 2 RepliesJust trying to get to grips with the Razor syntax - i had noticed that by default new views will have the following code in them;
@{

}

And the _layout.cshtml file accesses this variable
<title>@ViewBag.Title</title>
Is it just as simple as "the layout page gets fired last" or is there a firmer definition?

None of the methods in the HttpResponse class provide feedback if the data was sent or not, TransmitFile just does its job (or not) and does not provide any means of knowing the result.I was thinking of using the .Filter property but then again, the filter is based on the HttpResponseStream which does also not provide any feedback.
I have the following ViewModel:

This goes into a view like this:
[Code]....
Which as a result generates this:
[Code]....
Now, I'm trying to receive this data in a method so I can update stuff, like this:
[Code]....
But the above is not working. I've tried using [Bind(Prefix="user")] with no success. Before using this setup, I had all the user's properties directly in the ViewModel and the above method worked like charm.
What can I do to be able to process my POST request? I do not want to change my ViewData structure. I presume the answer to the question is not to difficult and lies only in adding something or changing some properties.
