    - No Touch Deployment.Net 1.1 Issues I have an app developed in VS 2003 using the 1.1 Framework that uses a private assembly. First I deployed this through IIS, adding the website to the trusted sites. These are in the same directory on the web server. When the site was in the trusted sites, it worked on the client with no problem. However I have removed it from the trusted sites, and created a code group (with full permissions for now) to the key used for both the exe and dll. I have also added the url with full permissions. When I attempt to download this, I get a filenot found exception. The fusion log indicates the private assembly cannot be found in the Appbase (Temporary Internet Files) directory on the client where the exe gets downloaded. I have checked the keys and version numbers are the same. I have tried in my development environment using Win 2K and XP and the local 192 address with the same results. I do not want to put this in the gac as it's a private assembly. Should this dll get downloaded automatically into Temporary Internet Files? Is there something else I need to do to get this to download? This is the fusion log: The operation failed. Bind result: hr = 0x80070002. The system cannot find the file specified. Assembly manager loaded from: C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322\fusion.dll Running under executable C:\Documents and Settings\Lawrence\Local Settings\Temporary Internet Files\Content.IE5\4HYDR86L\ViaPeak.TestSecurity.Main[1].exe --- A detailed error log follows. === Pre-bind state information === LOG: DisplayName = Viapeak.TestSecurity.Business, Version=1.1.4.0, Culture=neutral, PublicKeyToken=933b2f9fa4958519 (Fully-specified) LOG: Appbase = C:\Documents and Settings\Lawrence\Local Settings\Temporary Internet Files\Content.IE5\4HYDR86L\ LOG: Initial PrivatePath = NULL LOG: Dynamic Base = NULL LOG: Cache Base = NULL LOG: AppName = NULL Calling assembly : Viapeak.TestSecurity.Main, Version=1.1.4.0, Culture=neutral, PublicKeyToken=933b2f9fa4958519. === LOG: Processing DEVPATH.

    - Type of base pointer Take a look on this code: using System; using System.Collections.Generic; using System.Text; namespace BasePtr { class Program { class A { public virtual void Test() { Console.WriteLine("Method of base class"); } } class B:A { public override void Test() { Console.WriteLine("This is a real virtual method!"); } public void OldTest() { base.Test(); } public void ICanntUnderstand() { Console.WriteLine(base.GetType().ToString()); // WHY IS THE OUTPUT "B?! base class for B is A not A" } } static void Main(string[] args) { A a = new A(); // new A instance a.Test(); // "Method of base class" B b = new B(); // new B instance b.Test(); // "This is a real virtual method!" a = b; a.Test(); // "This is a real virtual method!" b.OldTest(); // "Method of base class" b.ICanntUnderstand(); // WHY IS THE OUTPUT "B?! base class for B is A not A" Console.Read(); } } } This code returns: Method of base class This is a real virtual method! This is a real virtual method! Method of base class BasePtr.Program+B I have a virtual function called Test() in class A. Also i have class B - it's derived from A and has overrided method Test() as well. I can easly access method A.Test() from class B - as written in function B.OldTest(). As well base object doesn't have method OldTest(). You can see it in this error description: Error 1 'BasePtr.Program.A' does not contain a definition for 'OldTest' C:\Documents and Settings\Vitaliy\My Documents\Visual Studio 2005\Projects\BasePtr\BasePtr\Program.cs 27 22 BasePtr base class for B is A and error above shows that base is BasePtr.Program.A. But code "base.GetType()" in any method of class B returns value BasePtr.Program.B. WHY?! Tag: Secure data protection under .NET 1.1 Tag: 123405

    - How to use ConfigurationSection Currently, we are storing our application settings in the registry, but we want them to be stored in config-files. In order to accomplish that I'm using the .NET 2.0 System.Configuration namespace. A couple of my own configuration class have already been derived from ConfigurationSection; ConfigurationProperty attributes have been added to the the properties as well. This all works very well, but I forsee some problems for the future: Question1: In release 1 (R1) configuration property 1 (P1) is available. In release 2 (R2) P1 is not required anymore and gets removed. When R2 tries to read the config-file it encounters P1 and throws an exception because it isn't defined anymore. How can I resolve this, without reconfiguring the application? Some of assemblies are registered for com-interop and need to be installed in the GAC. When assemblies are installed in the GAC, the full name (including version number) needs to be entered in the config-file in the attribute "/configuration/configSections/section@type". Question 2: The first release (R1) has version number 1.0.0.0 and the section defined in the config-file refers to version 1.0.0.0. The next release (R2) with version number 2.0.0.0 is installed. The config-file stays unchanged, because the configurations must be kept. When R2 loads the configuration an exception is thrown with the message that the assembly with version 1.0.0.0 couldn't be found. How can I upgrade the configuration from R1 to R2? Thanks in advance, Edwin Tag: Secure data protection under .NET 1.1 Tag: 123399

    - Seeking advice on best practice. We currently have a 4GL Application written in PowerBuilder and C. The PowerBuilder deals with the UI and the C does most of the business logic. We want to convert the C to VB.NET (as we use that in our web app and so am familiar with it), but don't know the best place to deploy it. The code is DB intensive, but also does a lot of calculations. We could just create an assembly that we call from PouwerBuilder on each client, or we could put it in a web service, or finally put it in the DB inself though that would mean our customers would have to upgrade to SQL Server 2005 (currently using 2000).

    - XmlTextReader disposal pattern Hi, I am amazed that XmlTextReader does not implement IDispoable. Is there any reason? In the case of XmlTextReader( Stream ) construction, if I wrap the Stream with a C# using statement like this: using( StringStream ss = new StringStream.... ) { XmlTextReader xr = new XmlTextReader( ss ); // ... use xr } Will this upset the XmlTextReader's finalizer because that would be executed non-deterministically long after ss has been disposed? If inside the using() loop, I called XmlTextReader.Close(), will this upset the ss.Dispose() call? Thanks. Leon Tag: Secure data protection under .NET 1.1 Tag: 123381

My home email server gets hit pretty badly with spam, and rather than using server software and risk losing email, i'd rather have some control over what gets deleted and bounced, and so forth. I've written a program that allows me to delete emails without downloading them, but can someone point me in the direction (either RFC or example) in any language (.NET, VB, Win32, etc).

If I have a STA component and I want to call one of its methods, which takes some times to complete and so I want to run it on a threadpool by using delegate.BeginInvoke(). Questions: 1) What kind of Apartment are the threads in the threadpool? 2) In legacy COM programming, I need to manually marshal the COM interface pointer to the other Apartment. If I simply pass the interface in .Net as a parameter when I call the delegate.BeginInvoke(), will .Net marshals the interface for me? If not, how do I to do this correctly? Thanks.

    - ClickOnce Deployment and the ConfigurationSection I have created an application that stores my configuration settings using the ConfigurationSection, ConfigurationElements, and ConfigurationElementCollection. Due to the complexity of my configuration (hence the collection piece) I did not try using the settings API. I have now gotten to the point where I need to worry about deployment and updates. ClickOnce deployment works great except for the fact that everytime my application gets updated, the settings will get lost. Is there a way to use ConfigurationSection along with ClickOnce and get the settings transferred on an update? Or do I need to investigate another method of updating or store my settings in another manner? TIA Seth Tag: Secure data protection under .NET 1.1 Tag: 123303

    - Suppressing .Net-BroadcastEventWindow issue Since migrating an application from .Net framework 1.1 to 2.0, I have an issue where when the app exits, I receive a popup error referring to the .Net-BroadcastEventWindow having an application error. Some searching through Google groups indicates that this is probably COM related. The app does in fact reference a legacy COM object (not ours to control) and if I don't access it, the error doesn't occur on exit. Unfortunately, that COM object is rather important, so I can't choose to not use it. Ultimately the app seems to work fine and without any errors relating to the COM object, and as mentioned, none of these issues existed in the 1.1 framework. At this point I'd just like to suppress the error if at all possible. Finding the cause is a good goal going forward, but I think this error is more aesthetic than consequential. Any suggestions?

    - Weird impersonation issue Just recently, we started getting a weird impersonation problem on one of our web apps (which used to work). IIS is set to use Windows Authentication, Anonymous is disabled Web.config specifies to use Windows Authentication, Impersonate = true Web server is trusted for delegation. The app goes out to a file server (on the local network) to retrieve an image file. Here is where it gets weird - If I run the app from my machine, the authentication and impersonation work and I can get the file to manipulate it. If I go to the Security Log on the file server, I can see my User Name and the Success Audit. However, if I go to any other computer, still using the same domain account, the Impersonation does not seem to make it all the way to the file server. I use System.Security.Principal.WindowsIdentity.GetCurrent().Name to get the user that the process is running under and it returns my user name, however, on the file server, there is a failure audit from WEBSERVER\Anonymous Logon. I have had another person test it, and they get the same results - it does not work from their machine, but if they log on to my computer, it works fine. Anyone have any idea what is going on here? Why is this only working from my computer? I thought I looked at all the relevant settings in IE, etc, but can't find any differences. Any ideas?

    - comparison reporting -- technique suggestions? hello, i have been given a challenging project at my org. i work on an inventory management web application -- keeping tracking of parts assigned to projects. in the past, i built an in-house ASP.NET reporting system. just your standard stuff -- user clicks on a report, the page executes a pre-defined SQL query, a dataset is formed and bound to a data repeater. that works well for us. and using some nifty CSS, my reports look good on screen & on paper. now, however, my users would like....comparison reports. with comparison reporting, theyd like the ability to: a) take a "snapshot" of a given live report, storing it for later b) compare a given report to one of the previously-stored snapshots the mechanism for this would ideally show them a screen of three sets of data: - new rows (parts added since the referenced snapshot) - deleted rows (parts that existed in the snapshot, but dont now) - changed rows (parts that existed in the snapshot, but have at least one different column) ideally, theyd like a technique that can be used generically for any of our current or future reports (but limited, of course, to same-report-type comparisons). ...some tall order -- this is nothing ive ever attempted before. a few ideas came to mind for doing this: 1) when a user takes a snapshot, the dataset is serialized into text, and dumped into a CLOB in the db. when the user later does a comparison, the desired CLOB is restored into a dataset. then code must be written to enumerate and evaluate the tables. rows matching one of the categories must be inserted into new a "results" dataset (consisting of the 3 tables for new/deleted/changed rows). 2) alternatively, some sort of "history" could be implemented on our tables on the (Oracle) backend -- like triggers that update new history tables, that log changes. then some means of comparing present-day data to the history tables must be devised. 3) investigate a 3rd-party reporting package that offers this ability. as i mentioned, ive never set about this particular task in my years of .net web apps. no idea on how it can or should be done. can anyone point me to references, or suggest possible solutions? thanks! matt Tag: Secure data protection under .NET 1.1 Tag: 123241

    - Embedded Resource Name Specification SUMMARY: I want to override the default embedded resource naming convention and excercise complete control over the name of an embedded resource within an assembly. DETAIL: For non-dependent files, visual studio names a resource according to the convention <default namespace>.<FolderName>.<FileName>. How can some other name for a given resource be specified? I am willing to manually modify the project file if necessary. Thank You, Chris Moore Tag: Secure data protection under .NET 1.1 Tag: 123237

    - Problem with using AppDomain/Assembly Loading in Queued Component Hi, After many searches online and cannot find the right solution for my issue, I decided to post my question here. If you can help or know something on this, please give me some hints? Thanks in advance ! ISSUE: I have a queued component ( COM+ serviced component and written in C#) that needs to load my .NET assembly dynamically into the AppDomain. Code goes like this: AppDomain newAppDomain = new AppDomain (); newAppDomain.CreateInstanceAndUnwrap("myClassName","myProjectNameSpace.myClass"); *** Note: myClass assembly is C# and I generated tlb for it and loaded the assembly into GAC and registry (via regasm). *** When running this queued component, I always got error "System.IO.FileNotFoundException: File or assembly name myClassName, or one of its dependencies, was not found." Looks like DLLHOST is looking into C:\WINDOWS\system32\ for my dll while my dll is actually in another directory (Note: the dll of queued component and my assembly are in same bin directory). What needs to be done to avoid this error ? Some error log: System.IO.FileNotFoundException: File or assembly name myClassName, or one of its dependencies, was not found. File name: "myClassName" Server stack trace: at System.Reflection.Assembly.nLoad(AssemblyName fileName, String codeBase, Boolean isStringized, Evidence assemblySecurity, Boolean throwOnFileNotFound, Assembly locationHint, StackCrawlMark& stackMark) at System.Reflection.Assembly.InternalLoad(AssemblyName assemblyRef, Boolean stringized, Evidence assemblySecurity, StackCrawlMark& stackMark) at System.Reflection.Assembly.InternalLoad(String assemblyString, Evidence assemblySecurity, StackCrawlMark& stackMark) at System.Activator.CreateInstance(String assemblyName, String typeName, Boolean ignoreCase, BindingFlags bindingAttr, Binder binder, Object[] args, CultureInfo culture, Object[] activationAttributes, Evidence securityInfo, StackCrawlMark& stackMark) at System.Activator.CreateInstance(String assemblyName, String typeName) at System.AppDomain.CreateInstance(String assemblyName, String typeName) at System.AppDomain.CreateInstanceAndUnwrap(String assemblyName, String typeName) at System.Runtime.Remoting.Messaging.StackBuilderSink.PrivateProcessMessage(MethodBase mb, Object[] args, Object server, Int32 methodPtr, Boolean fExecuteInContext, Object[]& outArgs) at System.Runtime.Remoting.Messaging.StackBuilderSink.SyncProcessMessage(IMessage msg, Int32 methodPtr, Boolean fExecuteInContext) Exception rethrown at [0]: at System.Runtime.Remoting.Proxies.RealProxy.HandleReturnMessage(IMessage reqMsg, IMessage retMsg) at System.Runtime.Remoting.Proxies.RealProxy.PrivateInvoke(MessageData& msgData, Int32 type) at System.AppDomain.CreateInstanceAndUnwrap(String assemblyName, String typeName) at myClassName.MyMethod..ctor() === Pre-bind state information === LOG: DisplayName = myClassName (Partial) LOG: Appbase = C:\WINDOWS\system32\ LOG: Initial PrivatePath = NULL Calling assembly : (Unknown). === LOG: Application configuration file does not exist.

    - Upgrading from .NET Framwork 1.1 to 2.0 Hi, We have an app that have been compiled to use .NET Framework 2.0. It runs fine from the server but from the workstation it generates an error message something like "This program could not start because the program configuration is wrong. If you reinstall the program it can solve the problem". I suppose it is .NET Framework that generates this message. In .NET Framework 1.1 we used to set access to full trust for the local intranet. I can not see such an configuration option for .NET Framework 2.0. Any idea what is the problem? Tag: Secure data protection under .NET 1.1 Tag: 123228

    - Missing referenced assemblies in compiled dll ... Hi, I have a project that references a couple of other dll:s. After I compile the project I use IL DASM to have a look on the Manifest of the compiled dll. The thing is that not all referenced dll:s are in there (I'm missing 3 of 7)! My problem is that I need to find all referenced assemblies by reflection (using GetReferencedAssemblies) ... Is there a explination to this? I could really need some help and ideas with this ...

    - WSE910 and 'Root element is missing.' I am having trouble with WSE3 and domain authentication\authorisation for a web service. When using a the 'NETWORK SERVICE' account for the application pool in IIS 6.0 the web service work perfectly correctly, we are able to call the web service end point and we can authenticate through our custom WSE authentication token manager, but when we switch over to a domain service account we have created to run the application pool we get the following error: 'WSE910: An error happened during the processing of a response message, and you can find the error in the inner exception. You can also find the response message in the Response property.' The inner exception states: 'Root element is missing.' The domain account is a member of the IIS work process group on the local box, it as the required security permissions for the directory where the web service is installed. What is very strange is that when this service account was made a domain admin temporarily the call worked perfectly fine. So the question is what permissions does WSE3 require so that we can get our domain service account to work correctly.

    - css failure on postback Hello all, I develop aspx pages for internal use. We use IIS 6, .net 2 and IE 6. In the head of the clientcode I call a css file like "@import url(../CSS/Styles.css);" All this runs fine. When I pubish the site to the server and call it from a clientmachine everything looks fine as well. But when there is a postback all styles are gone and the site is nearby unuseable. On the next postback it mostly looks fine again. Do I use the wrong way to implement the css or do I have to update the .net Framework with something? Thanks for help.

    - C# to C++ port Hi everyone, We have a dll component developed in C# and used by the other projects (exe) written in C#. This component has been tested and proved to be very robust component and so we are going to re-use it in another application (very large code base) which has been already written in unmanaged C++. What is the best strategy between the following two options: 1. Write a managed C++ wrapper around the C# component and use that wrapper in our unmanaged C++ project. 2. Port the C# component completely to an unmanaged C++ component and then use it in our unmanaged C++ project. The main advantage of option 1 is that it seems much quicker and we can also benefit from .Net framework library without having to re invent the wheel or use other 3rd party libraries. The main advantage of option 2 is that we are not going to get involved in the potential problems involved in mixing managed and unmanaged codes. Does anyone have any other ideas (maybe option 3 ...) or see another pros and cons in going with either option 1 or option 2? Any help would be appreciated Luca.

Greetings,

I am attempting to find a way to store a chunk of data inside of a C#.NET
application. I originally intended to use DPAPI via the Protect class in
System.Security.Cryptography. However, one of the consumers of this
application can only run the 1.1 framework and that class was added in 2.0.

Is there a way to hook the same functionality in the 1.1 framework?

Thanks,
Jacob

You can still use the underlying DPAPI by using platform invoke. See
www.pinvoke.net for example method signatures.
