Detect .net 4.0 in client

Posted By:      Posted Date: September 28, 2010    Points: 0   Category :ASP.Net
 

Hello,

I am trying to detect wether or not a client has version 4 of the .net framework installed.  Using the Request.Browser.GetClrVersions() method, I only get versions listed up to 3.5 SP1, but I do not get anything back indicating version 4.  Does anyone know how I can determine this?

 

Thanks

RemoteApp - Terminal Services detect client going into standby mode

  

Hi,

I have a RemoteApp running on the Terminal Server. Application is using a serial port. When client pc goes into standby mode everything is ok , I have a lot of problems when pc wakes up ( high CPU and memory usage ) . I was trying to prevent it but I can’t find any solution ( session remains active on the server ) . I decided maybe it would be good to try to detect moment when communication between client and server is interrupted and close application then. I had a look at WTS API but I can’t see anything meeting my requirements. Could some suggest some solution?

Thank you


How to detect client connection's network protocol?

  

Hi,

My SQL 2005 have both TCP/IP and Named Pipes enabled.  Is there a way (either within SQL Server or via a network tool) to tell what kind of protocol the client is actually using when making the connection to the instance?

Thanks

Use jQuery and ASP.NET AJAX to build a client side Repeater

  
By sending only data to the client, you can profoundly reduce the size of what you send and see a substantial increase in performance. You also allow yourself the ability to easily add features like light-weight sorting and paging on the client. This can not only improve your users' experience, but reduce server load and bandwidth requirements.

Practical Multithreading for Client Apps

  
Writing applications that use multiple threads is often considered an advanced programming task, prone to errors. In this month's column, I'll focus on a practical application of multithreading in Windows® Forms applications with some real benefits, while attempting to keep things simple. My goal is to present multithreading in an approachable way that addresses a very common need: writing applications with a user interface that remain responsive to the user.

How to detect and avoid memory and resources leaks in .NET application

  
Despite what a lot of people believe, it's easy to introduce memory and resources leaks in .NET applications. The Garbage Collector, or GC for close friends, is not a magician who would completely relieve you from taking care of your memory and resources consumption.

I'll explain in this article why memory leaks exist in .NET and how to avoid them. Don't worry, I won't focus here on the inner workings of the garbage collector and other advanced characteristics of memory and resources management in .NET.

Adding Client-Side Confirmation When Deleting

  
The JavaScript confirm(string) function displays its string input parameter as the text inside a modal dialog box that comes equipped with two buttons - OK and Cancel (see Figure 1). The confirm(string) function returns a Boolean value depending on what button is clicked (true, if the user clicks OK, and false if they click Cancel).

Client script not running

  

Dear all,

in my MVC 2 application, and in the shared Master Page I wrote this little script for menu handling :

<script src="../../Scripts/jquery-1.4.1.js" type="text/javascript"></script>
<script type="text/javascript"> $(document).ready(function () {   
       
     $('#nav li').hover(  
         function () {  
             //show its submenu

         },

Problem to obtain client IP on web service

  

Friends,

I'm having problems to obtain the client IP on web service. Here's my scenario:

One server with Windows 2003, hosting the web service using .Net Framework 2.0, with IP 10.0.2.50 and host name ServerTransaction.
Other server with Windows 2003, hosting a web application using .Net Framework 2.0, that consuming the web service on  ServerTransaction, with IP 10.0.2.51 and host name ServerApplication.
Many other computers on the local network (IPs: 10.0.2.80, 10.0.2.81, 10.0.2.82, ...) acessing the web application on ServerApplication.

On the code of the web service I've tried to use HttpContext.Current.Request.UserHostAddress or HttpContext.Current.Request.ServerVariables("REMOTE_ADDR") or HttpContext.Current.Request.ServerVariables("HTTP_X_FORWARDED_FORR"), but always I can only get the IP of ServerApplication (10.0.2.51).

Any idea or tip?


Thanks and sorry for my bad english.


Detect Browser Screen Size??

  

Hi Everyone,  I need to detect the size of the user's screen for mobile devices (especially the BlackBerry). I've read a lot of pages that seem to refer me to the Request.Browser object, but I'm finding that this object doesn't have the correct values. For example, I have a BlackBerry and when I use the Request.Browser to get the screen size, it tells me it is 640x480. Well, I know it's not that big since an image of 300px wide just barely fits. Also, when I run on my desktop browser, it also says my screen is 640x480. I can assure you, it is not 640x480! ha!

  How does anyone reliably get the browser's screen size?? Do I have to revert to some kind of JavaScript? If so, where can I read more about it? Will it be any more reliable? Someone must have an idea about this. Thanks in advance!!
