How to detecting Whether .Net Framework 4.0 Full/Client is available.

Posted By: Posted Date: September 29, 2010 Points: 0 Category :.NET Framework

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full can indicate whether .Net 4.0 is installed. But "the reg key exists" doesn't necessary mean .Net Framework is available.

For example, on Vista/Win7, if .net framework is installed, but user hasn't reboot the os as promoted, the reg key exists, but .net application failed to run.

Is there any way for C++ application to detecting whether .Net Framework 4.0 available?

C# and the Web: Writing a Web Client Application with Managed Code in the Microsoft .NET Framework

When the author wanted to build a middleware Web client to connect to other applications over the Internet, he realized that the XMLHttpRequest COM object was not sufficient for his purposes. In order to build a Web client using managed code, the author had to use the HTTPWebRequest and HTTPWebResponse classes provided by the Microsoft .NET framework. These classes are used in the sample project as a substitute for the less powerful XMLHttpRequest COM object, allowing the author to build a full-featured Web client. They also take advantage of all the benefits that the CLR and managed code have to offer.

Why does .NET Framework 4 client profile slow down boot time network creation?

I've been running a Windows XP sp3 KVM virtual machine for a long time now, and some recent update made the initial network startup go from a few seconds at boot time to around 90 seconds. Using Add/Remove program to uninstall recent updates points the finger at .NET Framework 4 client profile. With it installed, if I right click on network and ask for properties right after booting, there is a 90 second delay before the network dialog with the list of network interfaces finally appears. In addition, the network drive I have automounted at login is not accessible for the same 90 seconds. As an experiment, I tried going into the device manager and deleting the network interface, and if I reboot after that it takes 90 seconds for the new hardware wizard to appear. All these 90 second delays vanish if I remove this .NET update. The network comes up as soon as the system boots.

Microsoft .NET Framework 4 Client Profile

I changed from Vista to Windows 7. Every time I start my computer it says I need to install Microsoft .NET Framework 2.0 When I do that, the installation says it's already in my computer. I have looked and what's installed is Microsoft .NET Framework 4 Client Profile. What should I do? Also, my bluetooth has stopped working. Is this why?

Error: ASP.NET Ajax client-side framework failed to load.

Getting some errors after implementing the calendar control. Error: ASP.NET Ajax client-side framework failed to load. Here are some screenshots of the relevant info: Here's the scenario... I compile code locally, view the pages in a browser locally, and it all works fine. Another developer sits down at my machine, logs in with AD account (which create a local profile for his account on my machine), and gets these errors when viewing my locally compiled code. He then compiles the same code on my machine again just for a test, but still gets the same errors. Can anyone come up with any good reasons for this behavior? I put a call into MS and they suggested creating a new profile for the other developer with the errors since this appeared to be profile specific. Tried doing that with the same results. Help!

Differences between Silverlight and WCF(Full Framework) drawning

I have created a "Layout Editor" in Silverlight where the user can drag and drop text and image to create a custom layout. A sample of a Layout with one TextBlock can be seen here . The used font is Arial, size 50. This layout (not the image, but the layout itens properties like x,y,font, etc) is upload to the server by a WCF Service, which create the actual image and save it in the database. This is necessary because the text fields can have dynamic text, marked as '%text1', '%text2', where that dynamic values are in the database too. But, when i use the Bitmap and Graphics classes of the full .NET framework the DrawString method resulting drawning don't have the same aspect that your silverlight "counterpart". A result of the server generate image can ben seen here . Anyone can tell me if it is a resolution problem or something? I can't got a single clue about this. PS: If it is possible, move to the corresponding forum section. I use Silverlight UI, WCF communication and GDI+ drawning, so used WCF forum.

After enabling routing, get 'Ajax client-side framework failed to load"

Hopefully someone's come across this before... After I try using routing on my web form & load my page I get a few javascript errors one after the other: Error: ASP.NET Ajax client-side framework failed to load.Error: 'Type' is undefinedError: 'Sys' is undefinedError: Object expectedError: 'Sys' is undefined After fooling with this for awhile, I created a blank aspx page. It loaded fine. I drop a scriptmanager on the page & the errors above pop up. I've been using ajax controls up until this point, & they work just fine when I comment out my routing code so I know the toolkit is not corrupt. Its gotta be a config issue...just not sure where to go. It's a .net 4 web app on IIS7 Here's the code I added to my global.asax:void RegisterRoutes(RouteCollection routes) { routes.MapPageRoute("PageRouting","{department}","~/Subweb.aspx"); }protected void Application_Start(object sender, EventArgs e) { RegisterRoutes(RouteTable.Routes); } In my web.config I added the assembly: &

error: ASP.NET Ajax client-side framework failed to load.

Hi all,

I m getting this weird error "ASP.NET Ajax client-side framework failed to load." in my project which none of my other team mates are getting. Even I tuk the solutoin from the TFS so there is no chances of a code error any where because we all have downloaded the code from the same place in TFS.

N there shud not b anything wrong with the client browser also on my machine because i can browse the same page from the dev server perfectly. Its just breaking only when i m browsing that page on localhost.

We are using .net framework 4.0, windows 7 and we have AjaxControlToolkit version 1.0 in our project.

the only things which might differ in my case as compared to other machine and server are

- Virtual directory.

ASP.NET AJAX client-side framework failed to load

hi,

I run a asp.net 4.0 website. (I did the porting from version 3.5 to 4.0)

I receive the following error :

ASP.NET AJAX client-side framework failed to load

in a page where I set scriptmanager EnableCdn="true" and there is a microsoft ajax extension Timer on the page.

this is the code:

<asp:ScriptManager ID="ScriptManager1" runat="server" EnableCdn="true">
    </asp:ScriptManager>
<script src="http://ajax.microsoft.com/ajax/jquery/jquery-1.4.2.min.js" type="text/javascript"></script>

If I set EnableCdn="false" and refer to js locally es:

<asp:ScriptManager ID="ScriptManager1" runat="server" EnableCdn="false">
    </asp:ScriptManager>
<script src="../../jsScript/jquery-1.4.2.min.js" type="text/javascript"></script>

All works fine!

I receive the error only on the production server.
