I have two different database connection strings for a web form that I have to use when running on either my local pc or web hosting.best way to determine whether I'm running locally or on the server at runtime? I have dodgy logic at the moment which uses a local file to determine whether or not, but that means having to include and change the code on every page if I ever needed to.

I'm looking for a piece of code to convert an HTML file or code to an image file. I tried to do some search on google, I found a few but it only works on Windows application not web (asp.net).I'm basically trying to convert a formatted html page to an image at the server side.
View 2 RepliesI have a query:
Select a from tbl_abc where id in ( select id from tbl_xyz where mainid = 12)
When I am executing this query, it is taking 1-2 seconds to execute, but when I am using the same query in stored procedure, the below query is taking more than 5 minute:
If(Select a from tbl_abc where id in ( select id from tbl_xyz where mainid = 12))
BEGIN
-- CREATE TEMPORARY TABLE [Say: #temp1]
#temp1 => Select a from tbl_abc where id in ( select id from tbl_xyz where mainid = 12)
inserting the same value in the temp table
drop #temp1
END
what could be the reason of this? and how can I resolve this? I am running the SP from asp.net
Can any one please provide link for flow of query exection in sql
For eg.
FROM, [JOIN CONDITION, JOIN TABLE ...], WHERE, GROUP BY, HAVING, SELECT, DISTINCT, ORDER BY, TOP
Suppose when we write query, how that query will get execute behind. I would like to know about that.
Can you please provide ariticles or link related to this

View 1 RepliesI am using multiple threads in my .net web application. Certain functions may need to execute at any arbitrary time. However, I do not need these (and the entire application) to be fully asynchronous, as there is an acceptable tolerance in this execution time. Here is a rough example of what I need to do:
main()
{
loop
{
if (flagA) then doTaskA();
if (flagB) then doTaskB();
}
}
...where flagA and flagB are set via asynchronous timers in critical section. The actual execution of the requested tasks would thereafter run in series.
This is very easy to do in C/C++, etc. But I cannot find any access to such control in .NET, specifically in the web server/application architecture. It may be that it doesn't exist; however, I am assuming that the server must do something of this sort as it manages applications. I would like to hook into that somehow; even if via some application function that is called regularly during this loop.

why I am not getting the desired result. I want to retrieve records in DataReader and still I am not getting any result.
I have a big query that it execute in 4 minutes. (for example an important trigger)
I want to show situation of query or count of records that is affected in every 10 second in to a web page.
what should I do? (complete explain)
when I use 'RowNumber' = ROW_NUMBER() OVER(ORDER BY ColumnName) then due to orderby Column name consume 76% usage in execution plan . in such case what I have to do? I can see sorting taking much time in execution plan.
View 9 RepliesView on a button I have many different actions. So how to align them with the corresponding action in the controller. Means I want to know how many actions a View.For example, in the registration page.I have a button-Register and Login button. In the controller I have a registration action, an action Login. So how can I distinguish between those actions.
View 1 RepliesI need to capture the amount of time that ASP.net takes to execute each page request in my application, but I need to exclude any network latency. I am currently capturing render times by using the StopWatch class and starting the stopwatch during the OnInit method of the page lifecycle and stopping it after the Unload method completes. It seems that the Unload method includes the time it takes send the request to the client, thus including any internet/network latency. What is the last possible point I could stop the stopwatch in the Page Life Cycle that would not include the time it takes to send the request to the client. Would it be directly before the Unload event?
Related question: Does ASP.net finish building the response before it starts sending to the client? Or does it start sending asynchronously, while the response is being formed?
I am using ASP.Net 2.0 with IIS 5 currently.
I have this code in a class that all of my pages inherit from:
readonly Stopwatch _serverExecutionTime = new Stopwatch();
protected override void OnInit(EventArgs e)
{
_serverExecutionTime.Start();
base.OnInit(e);
}
protected override void OnUnload(EventArgs e)
{
_serverExecutionTime.Stop();
base.OnUnload(e);
}
UPDATE
I tried capturing the execution time at the end of the OnRender method, at the start of the OnUnload method and at the end of the OnUnload method. In all three cases the difference in times was at most 1 millisecond. Even when testing this from a client in Europe to a server in the USA, the times were identical.

View 1 RepliesIf I have something like the following:
<asp:TextBox id="test" runat="sever"></asp:TextBox>
<asp:RequiredFieldValidator runat="server" ControlToValidate="test"
ErrorMessage="Required"></asp:RequiredFieldValidator>
<asp:Label runat="server" id="lblStatus"></asp:Label>
if in the code behind, I set the label to "You must enter a value if the textbox is empty" to validate it on the server side and this is fine, but if javascript is enabled, I don't want to show the client side validation and the server side label together. Is this something where I would just have to disable the client-side validators if javascript was enabled?
We have a page that is opened in the child window using window.open. Now the user will copy the child's window Url and copy-paste it in the browser. We need to restrict this scenario. How should we do this. I mean I need to know in my page load method whether the request has come from window.open or whether the user copy-pasted the Url on the Browser's Address bar.
View 7 RepliesWe've got a client app which connects using TCP to a server. Additionally, the client app makes use of .NET remoting to talk to another piece of locally running code.
I'm tasked with creating a "Client Simulator" to do some testing, where we'd need to have 100's of clients connected simultaneously to the server. Ideally, this would work out great if I were to run each client in it's own space, such as a VM, but this is not logistically feasible.
how to handle this? Is there a tool that could do something like this? Or some sort-of .NET concept I could use?
I have a user control which contains a CustomValidator which is used according to whether a RadioButton is checked or not (there are several RadioButtons, I'm only showing the relevant one)
<asp:RadioButton runat="Server" ID="RadioBetween" GroupName="DateGroup" CssClass="date_group_options_control_radio" />
[code]...
There is some client + server side validation code (the server side code does exactly the same thing and is skipped for brevity)
<script type="text/javascript">
function ValidateDateFields_Client(source, args) [code]...
There are two instances of this control in the page. When running the client side version it hits the wrong one (the version of the control which is disabled). You can see from the generated HTML both are correctly specified. I'm not sure how .NET works out which clientside function to call given they both have the same name.

When calling Response.Cookie.Add(new HttpCookie("MyCookie", "objValue")); where does the cookie saved? on Client Machine or Server Machine?
EDIT:if saved in Client Machine, how can I read it from javascript then? I tried this kind of script.

var i, x, y, ARRcookies = document.cookie.split(";");
for (i = 0; i < ARRcookies.length; i++) {

I cannot get the cookie that I saved from code behind. When I look into the document.cookie object, it is just an empty string.

View 2 RepliesI am writing a C# MVC5 internet application and am having some trouble getting the 'ApplicationUser' object in a controller that I have created.
Code:
var userManager = new UserManager<ApplicationUser>(new UserStore<ApplicationUser>(new ApplicationDbContext()));

When I try to run this code, when a user is logged in, I am getting a null object for the 'ApplicationUser' user.
I am new to web page development so I want to ensure I am going down the right path with this new project. Currently, I am populating a mainGridView on my webpage with infomation from my MS SQL database. Two features I would like to add to this page is to be able to add filtering and hot linking/cell clicking events.
I was also planning on keeping the mainGridView dynamic, so that as a user clicks on a cell I could update the mainGridView with new information. Say all of Sammy Davis' movies. I am trying to do all of this inside of code and leave the aspx alone for the most part.
My plan was to embed textboxes into a secondary GridView to handle the filtering. The user could click on a button to filter the query set and the mainGridView would update based on the filter. Since the mainGridView is dynamic I need to have the filters to be dynamic as well.
