I'm writing a web part which has references to some other dlls. And these
dlls try to acces some web resources. So it seems I need to give them some
permission to accomplish it. But the problem is all the resource on the web
describes how to give permissions to webpart(cab) not to the dlss. So I
tried to put all the dlls into the gac for an easy solution. But it didn't
work out ? Is there a different policy for referenced dlls ?

Thanx in advance,
yufufi

What resources do your referenced DLLs access? You might have to give code
access security permission to the DLLs after you identify the resources they
need to have access to.

Indeed all assemblies in the "code calling chain" must have the
permissions needed. So if the assembly you call from your webpart
assembly needs to call a webservice, the called assembly as well as
your webpart assembly must have the WebPermission.

Strong name all your assemblies with the same public key and grant them
permissions using their common PublicKeyBlop.

What is also important is that if your webpart assembly is not granted
full trust it will only be able to call assemblies which have the
[assembly: AllowPartiallyTrustedCallers] attribute set. So you need to
set this attribute in the assemblyInfo file of the assmeblies your
webpart assembly calls.
