Hello,

I have found a problem running a .Net user control hosted by IE on
Windows Vista / IE7. This problem doesn't occur on Windows XP / IE7.

Here's a sample page that can be used to reproduce the problem:
http://www.softwaresigloxxi.com/Supe...ntControl.html

Please, I'm lost at this point. Can anyone tell me why the <object> is
failing to initialize on Windows Vista / IE7? I have tried adding the
website to trusted sites as well as lowering the security settings but
no luck.

I'm not sure if this is a security problem or a limitation on Windows Vista.

Thank you a lot in advance,

Vista uses UAC/User Account Control, which a .Net solution may have to
present security credentials to Vista in order for the application to run
properly with privileges, which the program presents to Vista in the form of
a UAC manifest the application uses to present the credentials. That's most
likely your problem.

Does he have to pay for it?

No, he doesn't have to pay for it. Being a .Net developer, then he should be
able to create the XML UAC manifest that the .Net solution will use to
present security credentials to Vista in order for the program to execute
with the proper privileges. The information is everywhere out there on the
Internet using Google.

Thanks for the tip. I will try it.

Hi,

To make sure UAC is breaking my client side control, I have disabled it
and restarted the system.

My user control still is not working on Vista/IE7 (it works on XP/IE7),
so may be UAC is not the problem in this scenario.

I will appreciate any help.

Thanks.

If you're using this 3rd party solution on the client side, then maybe the
control only works on XP or previous versions of the Windows based O/S
using the .Net Framework, and it flat-out doesn't work with Vista, which you
should verify with the 3rd party vendor that the control works with Vista.
..

Hi,

First of all, thank you for your quick answers. I appreciate your support.

I have to say that the user control works well on a Windows Form sample
application as well as on ASP.NET web applications.

You can test it here:
http://www.softwaresigloxxi.com/Supe...ary_Trial.html

It doesn't run as a hosted client-side control on IE7.

I have tried lowering permissions, adding the site to trusted zone,
disabled UAC, embed manifest to requiere permission elevation, ...

Well.. I'm begining to think that Vista has broken hosted client-side
..net controls.

Has anyone be able to host a .net user control on client-side on Windows
Vista/IE7?

Thanks!!
