And so Text Box doesn't have OnKeyDown event? Do you suggest any way to implement this?Note: I don't want to implement this with Javascript.
View 2 RepliesI am trying to prevent multiple simultaneous logins in my web application. I want to signout all/any previous authentications of a user when they login. Such that the current login remains the only one.
How do I go about calling FormsAuthentication.SignOut() for a particular user to invalidate any existing authentications.I have tried searching everywhere but no answers, only theories.
I'm after some thoughts on how people go about calculating database load for the purposes of capacity planning. I haven't put this on Server Fault because the question is related to measuring just the application rather than defining the infrastructure. In this case, it's someone else's job to worry about that bit! I'm aware there are a huge number of variables here but I'm interested in how others go about getting a sense of rough order of magnitude. This is simply a costing exercise early in a project lifecycle before any specific design has been created so not a lot of info to go on at this stage.
The question I've had put forward from the infrastructure folks is "how many simultaneous users". Let's not debate the rationale of seeking only this one figure; it's just what's been asked for in this case! This is a web front end, SQL Server backend with a fairly fixed, easily quantifiable audience. To nail this down to actual simultaneous requests in a very rough fashion, the way I see it, it comes down to increasingly granular units of measurement:
Total audience
Simultaneous sessions
Simultaneous requests
Simultaneous DB queries
This doesn't account for factors such as web app caching, partial page requests, record volume etc and there's some creative license needed to define frequency of requests per user and number of DB hits and execution time but it seems like a reasonable starting point. I'm also conscious of the need to scale for peak load but that's something else that can be plugged into the simultaneous sessions if required. This is admittedly very basic and I'm sure there's more comprehensive guidance out there. If anyone can share their approach to this exercise or point me towards other resources that might make the process a little less ad hoc
I have an asp.net 3.5 web application for which the client has requested that the security model allows (a licensing model) restricting the number of simultaneous users logged onto the website. I am not sure how this is achievable - I'm currently controlling membership via the AspNetSqlMembershipProvider.
View 5 RepliesI have to create a WCF service which can support 10,000 users simultaneous hits.
The job of the WCF service is to fetch a cached up XML object (we are using Enterprise Lib caching) and return it to the caller.
This WCF service will have to be publicly exposed. So I was thinking that we may have to use basicHttpBinding... I don't know, I may be wrong.
I have to test my asp.net web application for performance when there are simultaneous requests for the web site in my developer machine before deploy in production. How can I achieve this using Visual Studio?.(without using third party tools preferably Visual studio 2010 professional edition
View 3 RepliesI'm using IIS 7.0 on WS2008. I've implemented a simple login page that redirects to another simple page showing the Request.ServerVariables key/values. I'm using the built-in SQL membership provider. The website is on a DEV machine and there are no users on it.
When I login at the same time with 2 different users from 2 different locations (2 different public addresses) then one of the Request.ServerVariables page is the same as the other. That includes the client IP address which is then completely wrong. The authentication as well as the other cookies are wrong as well.
I checked the IIS log and it shows the correct client address as well as the correct login name. If I then reload the wrong page I get the correct data. Is there some concurrency issue in ASP.NET? I disabled the session and caching but I still get the same behaviour.
Is there a way in .net to display the text automatically when i type the first letter or word in a text box? I am looking for something like MS-Excel.. In MS-Excel, if the first word is given, automatically it displays the remaining texts, only if values are given previously.

I am quite new to ASP.NET. I am trying to display database data using text boxes and then using the same boxes to amend those data if the user wants and then sending them back to database.
I can display all the required fields from database onto aspx page. I have all the text boxes enabled. But when I edit the boxes and click submit, it stores the data that came from the database while I was displaying them meaning that any data updated on the text boxes are not captured at all.
My codes looks like the following:

i receive only the first two lines
and with the label
<asp:Label ID="Label112" runat="server" BorderStyle="None" Width="750px" BorderWidth="0" Text=' <%# Databinder.Eval(Container.Dataitem,"text_caption") .ToString.Replace(chr(13),"<br />") & "<br/>" & "<br/>" %>' ></asp:Label>
if the text is too big without an enter then the datagrid width becomes too big although the text is diplayed normal with new lines

I am getting data straight from the database into a data source. The data is binded in a repeater with link buttons.
The problem I am having is that the data in the database might have multiple spaces in the middle of the string however when being displayed on the front end only space is being shown. After thinking about it this is standard HTML behavior to remove spaces, I would have assumed that asp.net would have handled this with the rendering of the webpage. What is also happening is that when reports are exported to excel it only has 1 space instead of two.
Example:
2 spaces: "South Africa - Cape Town"
single spaces: "South Africa - Cape Town"
This is an irrelevant example but my data has real use for multiple spaces.
I want to display a background text in the textbox.
ex: The Title textbox in the stackoverflow Ask question page.
Needs: If i enter some text inside the textbox it should disappear.
I am using the following sample to display text in the background of the textbox. It is working fine too. http://attardi.org/labels/
Problem:
I want to increase the text box with. The box looks like it expanded but while typing the actual size is not expanded. I want to type text till 600px.
I want to use a multiline label but as the control is brouser dependent,even on setting the height width and wrap property of the label control i am unable to display a multiline text...It doesn't support every brouser in the same way...
