I'm creating a very simple chat application. It has an ASP.NET web page as front-end and a WCF service as back-end for storing the messages to a database.Everything works great except one thing; when Browser A enters a chat message I want Browser B to see the message as soon as possible (yeah, I know, that's the purpose of a chat).What I've done so far is to setup a trigger within the UpdatePanel, like this:
Is this the best approach or is there a better, yet simple, way to accomplish updating of messages. One drawback with this solution is that the textbox used to enter chat messages loses focus every time the Tick event runs.
I had create an application to allow user to register new project.Manager will chat with user base on the project ID(chat room id = Project ID) and store this conversation to database.
Example: User A register project A, other user cannot join the chat room A.
user should be logged in one browser and chat with some one.the same user should be logeed in same id in any other browser the user can get that chat messages in this browser also. but i have some problem inasp.net coding i can get chat messages only in which browser i chat to some one. so i need that chat messges in another browser also. how can i write the coding for that.
I'm developing chat application on asp.net mvc, in my app, user can create room and invite other join to chat, but don't need to save chat room information.So, I designed to save all chat message ,room information and user info in Session and clear it when owner close the room.I'm worry about stressing server when I save alot of data (include room info, user info, and message) in Session if there are up to 5000 rooms created and alot of messages transfered in that room.Is my solution good enough ? is it ok to save in Session ?
For error messages, validation faults etc you have
ModelState.AddErrorMessage("Fool!");
But, where do you put success responses like "You successfully transfered alot of money to your ex." + "Your balance is now zero". I still want to set it at the controller level and preferably in key-value way, the same way as errormessages but without invalidating the modelstate.
i want a continously running thread in my web application for sending mail to admin if the logged complaint of the user in not solved by technician within 24 hours.

I am looking for the directions on how to set a report to printcontinuously, without a paper feed. I have set one up using the LabelWizard, but how do I set it up in an existing report? I have lookedthrough all the property settings and cannot find any reference to it.
Is it possible to store gridview session data after each postback. I have a gridview and a checkbox within. Each time a user clicks the checkbox, I like to store the gridview ID in a session. After browsing through various pages, I like this session datato continuously store the information up to 20mins?
How can I continously store the session variable. Say a text box and if I enter 1 click on a hyperlink (where session variable is stored) return back to the page, enter 2 click hyperlink then I should get in the session 12?
I have a stored procedure that I need to execute from asp.net button , It takes more than 30 mins to execute. So here I need to show a message like "In Process" while execution and disable couple of links..Once the execution is done I need to show "Last processed data and time" and enable the disabled links. So in "In Process" stage we have to allow user to access other pages in the site. How it is possible?
I run a site with decent traffic (~100,000 page views per day) and sporadically the site has been brought to its knees due to SQL Server timeout errors.When I run SQL Profiler, I see a command getting called hundreds of times a second like this:
We use SQL Server to store ASP.NET session state. The above is the stored procedure called to grab the session state for a given session. It seems to be looping, asking for the same 2 or 3 sessions over and over. I found a promising looking hot fix that seems to address this exact situation, but it doesn't seem to have solved the problem for us. (I'm assuming this hotfix is included in the most recent .NET service pack, because it doesn't look like you can install it directly anymore). I added that registry key manually, but we still see the looping stored procedure calls like above (requesting the same session much more often than every 500ms) I haven't been able to recreate this on a development machine. When two requests are made for the same session ID, it seems to block correctly, and even try to hit SQL until the first page releases the session.
I want to know how to use auto refresh continuously in ajax update panel..What I want is,I've more than 6 update panels on my page and I want to all the panel to refresh toghether,continuously till I close the page.
I'm trying to connect to a site using digest authentication but it continuously gives "401 - Unauthorized" even the password is correct. Here's the sample code I'm using:
So I sometimes use app_offline.htm to take an app offline while I upload a new version.However, while I am in the process of uploading larger dll's, I get the yellow error-screen saying the dll could not be loaded.This seems to be out of sync with my expectations of what app_offline.htm does (stops the app entirely), and also provides the users with errors in stead of the nice app_offline.htm I put up.Am I doing something wrong or is this behavior by design?
can Visual Studio 2008 be All-In-One tool to integrate source code continuously from team members, build, unit test?
Having used Visual Studio Team Edition 2005, unit testing each method within VS itself. I strongly believe that it is feasible to add-on tools. Example ankhsvn tool to use SVN from Visual studio [URL]
In my investigating i have come across number of tools(shown below) to use with Visual Studio 2008 professional
Development tool:- Visual Studio 2008 professional using Subversion as source control tool. Continuous Integration:- Hudson or Cruise control Build tool:- NAnt Testing:- NUnit, Selinium As Visual Studio 2008 can be used for unit testing I think NUnit is out of consideration.
In the same way i would like to have any other tools/add-ons to Visual studio to implement continuous integration, building and unit testing. This process should be automated such a way source code between team members is continuously integrated, built and unit testing is done as configured.
Objective is to use few number of tools as add-on to Visual Studio or achieve most from Visual studio itself (example unit testing). Visual Studio should be all in one tool.
I am aware that Team Foundation Server best suits my requirement, but it is out of scope due to its cost.
i am developing chat application using vb.net and asp.net where i am having a div tag inside which i am displaying the messages posted by the online users what my problem is when the messages are more and exceeds the height of the div tag then i am not comfortable to view the previous messages because i have set the scroll bar position to always to be pointed to bottom.
how it works to be on the chat site Facebook.When I watched this chat via Firebug, so there they have made with retrieving messages over and over again in the loop.
I used setInterval ("function", time);They're just loading the chat for a change.So how does such a professional ajax chat?
