Are You in the Know?: Find Out What's New with Code Access Security in the .NET Framework 2.0

  

Unlike role-based security measures, code access security is not based on user identity. Instead, it is based on the identity of the code that is running, including information such as where the code came from. Here Mike Downen discusses the role of code access security (CAS) in .NET and outlines some key new features and changes in CAS for the .NET Framework 2.0.

Return of the Rich Client: Code Access Security and Distribution Features in .NET Enhance Client-Sid

  

Rich clients employ many of the features and conveniences of the operating system they run on, and the list of these features has been growing since the dawn of the PC. But as apps have migrated to the Web, the trend towards increasing client-side functionality has ground to a virtual halt. There are several reasons for this; chief among them are security and deployment problems. But that's all about to change. With the .NET Framework, you can participate in building the distributable rich client of the future. In this article, the author enumerates the pertinent features of .NET that will allow you to build safe, easily deployable controls. The features discussed include managed code, code access security, versioning control, Windows Forms classes, and isolation.

Security in .NET: Enforce Code Access Rights with the Common Language Runtime

  

Component-based software is vulnerable to attack. Large numbers of DLLs that are not tightly controlled are at the heart of the problem. Code access security in the Common Language Runtime of the Microsoft .NET Framework addresses this common security hole. In this model, the CLR acts as the traffic cop to assemblies, keeping track of where they came from and what security restraints should be placed on them. Another way the .NET Framework addresses security is by providing preexisting classes which have built-in security. These are the classes that are invoked in .NET when performing risky operations such as reading and writing files, displaying dialog boxes, and so on. Of course, if a component calls unmanaged code, it can bypass code access security measures. This article covers these and other security issues.

Showing Designer error for Silverlight App when trying to access resource which contains code e.Resu

  
Environment is: Silverlight 4, VS Studio 2010. Designer is showing error in a Silverlight App when trying to access a resource as below. And there are no build or runtime errors. Extensive research found that, in the "InvestorsProvider" class I am using wcf services, which has a callback method. In the call back method I am using this statement "this.MyProperty = e.Result" where e.Result is ObservableCollection. If I remove the e.Result it is not showing any designer problem. <UserControl.Resources> <local:InvestorsProvider x:Name="investorsProvider"></local:InvestorsProvider> </UserControl.Resources> Here is the error System.Reflection.TargetInvocationException [Async_ExceptionOccurred]Arguments: Debugging resource strings are unavailable. Often the key and arguments provide sufficient information to diagnose the problem.

I m having an application where I loads dlls dnamically and from that loaded dll is use to read some machine settings,files etc. I want full access for my application so I want to disable CAS setting for my application.

I have tried "SecurityManager.SecurityEnabled =  false" but I m failing to set this property from my application.

I have tried caspol -security off from VS command prompt but from my code I always gets TRUE for SecurityManager.SecurityEnabled.

I m using CLR v2.0

Please let me know how I can disable CAS from my application.

TCP Error Code 10060 when attempting to access WCF Service hosted by WIndows Service from client run

  

Hello all,

We have a Framework 3.5 WCF Service which is in turn hosted in a Windows Service using Net.Tcp Binding. SvcUtil is used to generate the proxy which is used instead of a service reference in the client code. We are also using Tcp Port Sharing. The endpoint address is net.tcp://HostMachineName/MyServicePath. The service logs to the Event log and everything works perfectly on the same machine.

When attempting to run the client from a different machine we are getting TCP Error Code 10060 errors. Below is the error message:

System.ServiceModel.EndpointNotFoundException: Could not connect to net.tcp://HostMachineName/MyServicePath. The connection attempt lasted for a time span of 00:00:20.8592415. TCP error code 10060: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 111.22.333.444:808.  ---> System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 111.22.333.444:808... The IP Address displayed was the correct IP Address for the HostComputerName.

Has anyone encountered this problem? Also, client specs say no config files, so anything that wo

Link/Connect SQL CE Table to Access MDB for VBA Code Processing

  
I'm hoping to connect an SQL CE file (main.dat) to an Access DB so I can run some vba code which:

1. Uses DAO to open a recordset (a table in the SQL CE DB)
2. Uses a field containing paths to mp3 files to extract the id3 tag data
3. Update an existing field from the same table/Same SQL CE DB

I've looked around and can't seem to find any ODBC driver(s) for SQL CE.  Got some info from Erik who suggested I post here.

Thanks in advance!


EDIT:  I just now was able to get Erik's code to work in Excel from my DB.  But I'm not sure how to send it back to the SQL CE DB from VBA... Is it possible?

Issue with Code Access Security Policy - deploying a third party dll to bin

  

Okay, i think most of you guys out there use wspbuilder to build the wsp solutions and to deploy it. So here is my problem.

I'm working on a SharePoint solution which makes use of a third party dll (Telerik for Asp.Net Ajax - Telerik.Web.UI.dll) for rich experience. Since Telerik dll is a common assembly i have to deploy it to the bin folder of the webapplication instead of GAC. So here comes the problem.

WSPBuilder automatically deploys the dll to gac if the dll presents in the GAC folder. To deploy the telerik dll in bin i created the folder 80\bin and copied the dll there. I tried to build the wsp again and then went through the manifest.xml created. Great. The deployment target for the dll changed to WebApplication and wspbuilder was smart to create the cas policy itself.
