Falied to grand permission when host a .NET control in IE web page

[Lei Jiang]

I have a winform control hosted in IE web page. When the client side is
Win2000, the page works ok. However, when I view the page from Win2003, it
shows nothing. I could find some error message from the "Temporary Internet
Files" folder :

Pages from other web site can be correctly viewed in my Win2003 machine.I
checked the MagicLibrary.dll and found it has a lot of interop code to
access User32.dll and GDI32.dll. Is that the reason? How to configure my
machine to view the page?Thanks!

Lei,

On your windows 2003 box, you have to set permissions
for 'http://10.147.130.245/dwmweb/Flag.DWM.dll' to execute on
your system under .NET Framework.

First have a look at:
[url]http://support.microsoft.com/?id=311295[/url]

and do this:

<quote>
1.. Start the .NET Framework configuration tool, Mscorcfg.msc.
2.. Expand each element in the following path:
My Computer/Runtime Security Policy/Machine/Code Groups/All
Code/LocalIntranet_Zone

Right-click the LocalIntranet_Zone node, and then click new.
3.. Name the new code group TestVBNetCtrl, and then click Next to display
the Choose a condition type dialog box.
4.. Select URL as the condition type, and then type [url]http://ServerName/*[/url] in
the URL box.
5.. Click Next to proceed to the Assign a Permission Set to the Code Group
dialog box.
6.. Click Use existing permission set, click FullTrust, and then click
Next to finish.

Of course I have configured that. It can't solve the problem.

All the Win2000 client can run it after being configured(just as stated in
the document), but Win2003 client failed in the same situation.

[M. Zeeshan Mustafa]

The problem is as it clearly states in error message that permissions
by Flag.DWM.dll cannot be granted (inherited) to MagicLibrary.

Only fully trusted callers (assemblies) can use strong named assemblies,
unless AllowPartiallyTrustedCallersAttribute is used in sn assemblies
to allow partially trusted callers.

If you give partial trust to your assembly, and your
assembly is calling an assembly which is Full-Trust only assembly,
you may receive exception.

Try giving full-trust permissions to MagicLibrary explicitly...

Thanks. But none of these assemblies is strong named assembly.

BTW: How to give full-trust permissions to MagicLibrary explicitly?

Give full trust permissions to your assembly, and it should
be inherited by MagicLibrary.
