    - Can't UseEncryption with MSMQ I'm trying to encrypt the body of my msmq messages by setting the UseEncryption property on the message. This throws an exception UnsupportedFormatNameOperation. I'm using msmq for ipc on a single server, the queues are all private and there is no AD domain - the server is a member of an NT4 domain. I'm specifying the queue as ".\private$\QueueName" and everything works fine until I enable the UseEncryption switch. I haven't been able to find any info in MSDN relating to this; msdn just says the requirements are the standard platforms (Windows 98, Windows NT 4.0, etc). The alternative is to encrypt the data myself prior to sending but that seems like a lot of effort when UseEncryption should be able to provide the same functionality. Any clues would be much appreciated. Thanks Dave Tag: Internet Explorer does not Fire events... Tag: 106440

    - Can I block the .NET Framework via a GPO Hello: I need to block .NET Framework v2.0 which is now downloadable via WindowsUpdate. I am pretty sure I can block this with a gpo. When WinXP SP2 came out initially you could block that with a gpo. Does anyone know how I can do that? Harrison Midkiff Tag: Internet Explorer does not Fire events... Tag: 106438

    - No dot net tab in IIS Hello all, I am running Windows XP Pro. I have installed the .net framework and SDK v 1.1, and IIS is correctly installed. I don't have a .net tab under "Default website".. I have read other posts where the solution is to run aspnet_regiis -i, unfortunately this does not work for me. I have put my computer through a complete re-image already, hoping that would clear up the problem, but no luck. Any help appreciated... thanks. Dave Tag: Internet Explorer does not Fire events...

    - Copy Local and GAC I have an assembly that uses a third-party object that is installed in the GAC. I set the references "Copy Local" property to true and compile my assembly. The third-party object is in fact copied to my output directory. I have another assembly that uses my first assembly. I set the references "Copy Local" property to true and compile my assembly. I would expect that I would see both my first assembly and the third-party assembly in my second output directory, but I don't. Why? Tag: Internet Explorer does not Fire events... Tag: 106421

    - WebResponse.Close() not disposing unmanaged resource? I have a .net app that uses a lot of calls to System.Net.WebRequest, and it appears to be leaking memory. I've spent a couple of days working with the excellent .net memory profiler from Scitech (http://www.scitech.se/) trying to find the leak, and all I've managed to find is that the win32 (unmanaged) heap seems to keep growing. I wrote this (pretty non-realistic) code in a test app to try duplicating the problem: while(true) { try { System.Net.WebRequest req=System.Net.WebRequest.Create(@"http://chris/TestWebService/TestService.asmx?WSDL"); System.Net.WebResponse resp=req.GetResponse(); resp.Close(); } catch(Exception ex) { MessageBox.Show(ex.ToString()); } } Note that this was just inside a button click event of a winform application. The exception condition never got hit, and the app just kept hammering away at my local web server. Checking the profiler, I saw the number of undisposed instances of System.Net.HttpWebResponse, System.Net.ConnectStream, and System.Threading.ManualResetEvent increasing with each iteration. Shouldn't the resp.Close() statement release the resources? There's nothing in the documentation about doing any sort of disposal on the request object, so it appears that only the response needs to be disposed, and so far, that doesn't seem to be happening. I've also tried the above code casting the response to an HTTPWebResponse, but that has no effect. I also tried removing the resp.Close() statement, which had no effect (the undisposed objects still showed up in the profiler). Is there something else I need to do to fix this memory leak?

Hi, I migrated one of my solutions(VB.NET 1.1, containing a Windowds Forms project and a Class Library project) to the 2.0 Framework using the inbuild-wizard.

    - Custom channel sink without using RemotingConfiguration.Configure Is there any way to implement custom channel sinks while remoting without using the RemotingConfiguration.Configure() method? I really don't want to store the data in a .config file as I need to change the configuration parameters, and do not want to have to write a new file each time. I have found plenty of examples of using custom channel sinks with the Configure method, but none that do not use this. Is this possible? If so, can someone provide an example of how to do this? I am about ready to use Reflector to see what the .Configure() method does, but I am sure it is quite in depth and would take significant time to digest.

    - StreamReader.OpenText and Unicode I am trying to read log files into a String but sometimes the log file doesn't contain encoding marks at the beginning of the file to indicate to readers what kind of file it is (Unicode, UTF8 etc). For example, COM+.log in the windows directory does not contain any encoding marks but the text is written as Unicode. For these instances, what are good work-arounds to auto-detect the log file as Unicode and read the file as a String? Notepad.exe does this and I am wondering how they go about auto-detecting the encoding when encoding marks do not exist. For example, if encoding marks do not exist, do they just read the second byte in the file and if it is zero assume the file is Unicode? Thanks Tag: Internet Explorer does not Fire events...

    - Suggestions for a architecture I have a database table with columns of URLs and datatimes. At the precise datetime I would like to a perform HTTP Get request to the URL. There may be multiple requests to different URLs that need to be performed at the same time. It doesn't seem efficient to have a service polling the database every second looking for requests to process. I have been doing a bit of research into MSMQ and SQL Service Broker in SQL Server 2005. But the messages seem to be processed in the order they arrive not on a specific datetime value. Any pointers for what would be the best design approach?

    - FileSystemWatcher on startup? Hi. I am supporting a Windows service that uses FileSystemWatcher to monitor an inbound directory for new files. If the service is shutdown and files are dropped to the inbound directory, those files are not picked up by FileSystemWatcher at service startup. This is a rare circumstance where the service will be down, but it does happen occasionally during maintenance windows. The solution to this problem that is in the code now is that a Timer has been introduced to watch the directory as well. That forced the addition of some thread mgmt (lock{}) so that both the timer and the FileSystemWatcher (on separate threads) don't process the same file. Is there a way to get FileSystemWatcher to pick files up at startup? I'd love to bag the Timer (it's always a special feeling ditching code). :-) Thanks, Jeff Tag: Internet Explorer does not Fire events... Tag: 106364

    - Large page faults issue in .net application I've PerfMon-ed our application for several days now and it consistently averages 2000 Page Faults/sec, and accumulates on average about 4 mill page faults during 35 mins. During the same monitoring time of 35 mins, there is never any sustained occurence of hard page faults -as a matter of fact, almost on avg 98+ % of the entire time the app is experiencing soft page faults. The processor rarely ever gets over 70-80% for a sustained period of 30 sec during the entire 35 mins. % Time in GC averages 3%. Besides stats, we also notices that our Working Set gets consistently trimmed every couple of minutes in the order of 20-30 MB and sometimes even more. I also see this is directly correlated to the managed object heap bytes being trimmed as well - exactly the same graph line behavior. When WS gooes down, available memory goes up. I also see that the largest number of gc collections are Gen 0s, followed by Gen 1s and the smallest Gen 2s. We monitored a slew of other Perf counters - so if u need any other info to help, I can supply the perf counter values readily. QUESTION - How do I make sense of the page faults being so excessive...? Can you supply some info and or documentation to help me determine if this is a good, bad or expected behavior for .NET apps...? I tried researching in lot of places but no luck to help me. Almost every doc I find outlines that if you have hard page faults, that is a bad thing, while soft page faults are ok. (Sustained period = we selected 30 secs - example -> so if the %Processor Time is over 80% for 30 secs or more we would get concerned). Tag: Internet Explorer does not Fire events... Tag: 106361

    - ISAPI extension change .Net default stack size Okay this is ugly, but here it goes. We have an unmanaged IIS ISAP extension. We use the worker thread approach and spin up our own threads creating the stack size that we want. Later in our code we have a C# module that get's executed and we begin executing managed code here. Inside of the managed code we we start a thread using the below approach (for timeout). The problem is that there are certin cases where the new thread we created is running out of stack. Sure if we had an exe we could use editbin to increase the default size of the stack. But I don't think this works for dll's. Is there anything we can do to change the default size of the stack that will be created in the C# module? It is important to note that the C# module at the end of the day executes some other unmanaged C++ code. There is no recursion to eliminate there is just a very structured and complicated application (in both good and bad ways but we really can't change too much here). Our other thought is to rewrite C# module in good old unmanaged C++ so that we can make calls that allow use to create threads of arbitrary size. Regards Frank // ScriptThread is our class that does the work ScriptThread st = new ScriptThread(method,null,Thread.CurrentThread,"",null); ThreadStart threadDelegate = new ThreadStart(st.Run); Thread newThread = new Thread(threadDelegate); newThread.Start(); newThread.Join(_nTimeoutSeconds *1000); newThread.Abort(); Tag: Internet Explorer does not Fire events...

    - Versioning 1.1/2.0 I could need some advice on how to work with a project that should work with framework 1.1 and 2. Currently i work on a VS solution with about fifteen projects within. Most of them we convert to VS2005 but a few of them are base libraries that are used in VS 2003 solutions / dotnet 1.1 as well. To handle this, we now maintain a version of the solution/projects files for each version. How can i make sure, that when you work on the VS2005 projects you won't mess up the code for 2003? Two things i have in mind are - Configure the base library projects to only use ISO-1 csharp features? (i don't know even know if that setting is really exactly the same as dotnet1.1) - Set all references of this libraries back to the 1.1 framework dlls? (but i have no glue if that is such an good idea to mix the versions and then it is compiled with dotnet 2.0 csc anyway) Did i miss some project setting for the target framework so i could just say "this specific project has to work with and is compiled/compilable on framework 1.1"? btw: for specific code for dotnet2 that honors deprecated/new functions i have defined a constant on each vs2005 project DOTNET_2 and then #if DOTNET_2 #else #endif handling in the code. Isn't there really no way to determine the framework on compile time in the code? When i think back to C++ times, microsoft placed all kind of #defines into the headers with most of them noone had an idea what they could be good for so how come i don't find some that says "I_AM_DOTNET_2_AND_COMPILED_ON_A_MACHINE_WITH_OFFICE_AND_SQLSERVER_INSTALLED" or something like that :) Tag: Internet Explorer does not Fire events...

    - Trouble Selecting a ListViewItem Programmatically I know it, I know it. It's come up a lot. I've done the Googling, but the standard answer doesn't do what I expect it to. For the record, the standard answer is: "Set the Selected property of a ListViewItem to true." I also know from MSDN that the selection won't really take effect until the ListView has focus. My specific problem is that setting item.Select = true doesn't actually select my item (or at least, doesn't highlight it). I'm implementing a search feature, and the highlighting is kind of important. Even more curious, Microsoft's own C# code sample at ms-help://MS.VSCC.v80/MS.MSDN.v80/MS.NETDEVFX.v20.en/CPref17/html/P_System_Windows_Forms_ListViewItem_Selected.htm (might need to get there through VS2005 documentation) illustrates my problem exactly. The first list item does not get selected on list population, even though the code tells it to do so. Selection seems to work after a click on the button, but not before. 1) What's so magical about that button click? 2) Is this a bug in the framework?

    - System.Xml.Serialization - deserializing xml to types created in dynamic assembly Hi All, I've been working on a saved dynamic assembly that holds all the types and corresponding xml serialization attributes I need to deserialize xml documents into objects. You might wonder why I would choose a dynamic assembly over simply coding the types at compile time - the simple answer is I don't know what the types will be before hand and I only have an xml schema (from which I build the dynamic assembly) with various attributes that change frequently. Since the schema only defines data types (methods,events,delegates could probably be defined within xs:appinfo tags but in my case they are not), I needed a way to add functionality to these dynamically created classes which were otherwise, nothing more than just data stubs. The method I chose was to define (at compile-time) abstract base classes from which classes in my dynamic assembly could inherit. Now these simple data-stub classes had a complement of methods to enable them to do more than simply hold data in fields. Unfortunately, it seems that since my dynamic classes now inherit from classes defined at compile-time, the xml serializer gets confused (see error and stack trace below). It worked fine before I added the inheritance - maybe I need a reference (somehow) to the hardcoded assembly containing the types I inherit from in my dynamic assembly. Any suggestions? Thanks in advance, Rein [[error and stack trace]] "An unhandled exception of type 'SystemIO.FileNotFoundException' occurred in mscorlib.dll.

    - Uniformaty Now I know that VS2005 has master pages and webparts etc etc. However, at present I am forced to work with VS2003 so I have a couple of basic questions related to the subject matter for which I am hoping to acheive inspirationan and or direction. I want to create my new site with a high degree of consistancy and managability. The perfect way to do this is to choose something other than asp.net 2003 to do it in, like I dont know , lets say front page for example where I can use dynamic templates to create editable areas much the same as I do on 2005 ( If i were able to use it ). But thats not the case. So, Im trying to devise a way to acheive this. As far as I am aware, I cant inherit aspx forms, so this leaves me with ( AFAIK ) creating a template to copy from and then altering the code for each new page. I dont want to use Includes or Frames, OR MS Positioning, so Im thinking about using Flow layout panels and adding custom controls to do the menus etc. Does anyone have any pearls of wisdom for me before I go ahead and get myself in a whole heap of trouble ? PS: If any of my assertions above are incorrect, Im sure ( and hope ) that someone will let me know. -- Best Regards The Inimitable Mr Newbie º¿º Tag: Internet Explorer does not Fire events...

    - encrypting/ decrypting xml based dataset with RSA My webdatabase has RSA encrypted Credit Card info which i download to my windows app via a webservice. A dataset in the windows form code then decrypts the data with a private key and displays on the form. I want to create a cached version of the data in xml, therefore the cc data has to be re-encrypted before it is saved to the local drive. To do this I have both pub and private keys with the user app on their PC's. This is where i seem to have a problem as when the data is re-encrypted it changes. My encryption/ decryption code is as follows: ################################################### Function RSADecrypt(ByVal instring As String) As String If instring.Length > 0 Then Dim RSA As RSACryptoServiceProvider = New RSACryptoServiceProvider(1024) Dim sr As StreamReader = New StreamReader("RSAKeyPriv.xml") Dim s As String = sr.ReadToEnd() sr.Close() RSA.FromXmlString(s) Dim inp As Byte() = Convert.FromBase64String(instring) 'This always throws an exception "invalid key" :((( Dim outp As Byte() = RSA.Decrypt(inp, False) Return System.Text.Encoding.Unicode.GetString(outp) RSA.Clear() Else Return instring End If End Function Public Function RSAEncrypt(ByVal instring As String) As String Dim RSA As RSACryptoServiceProvider = New RSACryptoServiceProvider(1024) Dim sr As StreamReader = New StreamReader("RSAKeyPub.xml") Dim s As String = sr.ReadToEnd() sr.Close() RSA.FromXmlString(s) Dim inp As Byte() = System.Text.Encoding.Unicode.GetBytes(instring) Dim outp As Byte() = RSA.Encrypt(inp, False) Return Convert.ToBase64String(outp) RSA.Clear() End Function ############################################### my dataset manipulation to decrypt the data so it can be displayed on the form is as follows: ################################# Public Function SyncOrderHeader() As DataSet Try dsH = ws.SyncOrderheader If File.Exists("orderheader.xml") Then Dim cache As New DataSet cache.ReadXml("orderheader.xml") ' synchronize the data with cached file If (cache.HasChanges()) Then dsH.Merge(cache.GetChanges()) 'ws.UpdateCustomers(dsH) dsH.AcceptChanges() File.Delete("orderheader.xml") End If End If Catch er As Exception MessageBox.Show(er.ToString) online = False StatusBar.Text = "Working in offline mode" ' try to get the data from the cache file If (File.Exists("orderheader.xml")) Then dsH.ReadXml("orderheader.xml") End If End Try Try dsH.Tables(0).TableName = "OrderHeader" Dim r As DataRow For Each r In dsH.Tables(0).Rows r.Item("cc_Type") = RSADecrypt(r.Item("cc_Type")) r.Item("cc_OwnerName") = RSADecrypt(r.Item("cc_OwnerName")) r.Item("cc_ExpiryDate") = RSADecrypt(r.Item("cc_ExpiryDate")) r.Item("cc_StartDate") = RSADecrypt(r.Item("cc_StartDate")) r.Item("cc_SecDigits") = RSADecrypt(r.Item("cc_SecDigits")) r.Item("cc_IssueNumber") = RSADecrypt(r.Item("cc_IssueNumber")) r.Item("cc_CardNumber") = RSADecrypt(r.Item("cc_CardNumber")) Next Catch ex As Exception MessageBox.Show(ex.ToString) End Try Return dsH End Function ########################################## When my app closes the cc columns in the dataset are encrypted again using: ########################################### Dim r As DataRow For Each r In dsH.Tables(0).Rows r.Item("cc_Type") = RSAEncrypt(r.Item("cc_Type")) r.Item("cc_OwnerName") = RSAEncrypt(r.Item("cc_OwnerName")) r.Item("cc_ExpiryDate") = RSAEncrypt(r.Item("cc_ExpiryDate")) r.Item("cc_StartDate") = RSAEncrypt(r.Item("cc_StartDate")) r.Item("cc_SecDigits") = RSAEncrypt(r.Item("cc_SecDigits")) r.Item("cc_IssueNumber") = RSAEncrypt(r.Item("cc_IssueNumber")) r.Item("cc_CardNumber") = RSAEncrypt(r.Item("cc_CardNumber")) Next ########################################### Any ideas why this wouldnt work?

    - Security settings for intranet zone Hi, I have a problem executing a managed application from a server's share - hopefully, someone can give me a hint. The application and all DLLs are signed with a key, therefore have a strong name. Now, I was assuming that if I create a code group under the "Organization" level with that strong name as criterium and the FullTrust permission set, my assemblies should be able to access all ressources (including reflection which is causing all the trouble); but when executing the application, I get a SecurityException. I tried setting that policy to LevelFinal and Exclusive, but still that nasty SecurityExceptions keep popping up. The only way I found to make it work is when I set the LocalIntranet zone security setting to the highest level. But of course, customers will not be wanting to grant full access to just any assembly on the intranet. Therefore, my questions are: 1. How does the zone security setting affect the runtime policies? 2. How can I grant my application FullTrust permission set, but only my application? Thanks for any hints on this!

    - Win32Exception on calling myProcess.start() method Hello, Probably this question has been asked yet, but I can't find any answer to my problem. I have an ASP.NET application, which call a method which has to launch a batch. To do it, I use an instance of the Process class. But when I try to execute the start() method of this instance, it throws an exception : " Win32Exception (0x80004005): Access is denied" I think there is a way by using the System.Security.Permissions namespace, but I can't find how to do it. For information, when I change the identity of the pool which support this application in IIS and set it to an administrator, it works ... but I'd prefer not to do it ;) many thanks Tag: Internet Explorer does not Fire events...

    - Distributing .NET Framework 1.1 SP1 Hi! I am about to distribute .NET Framework 1.1 SP1 to a bunch of clients. I thought that there were a redist version of the framework including SP1, but after looking around this doesn't seem to be correct. Can someone verify this? My conclusion is that i have to dist .NET Framework 1.1 (dotnetfx.exe) as well as SP1 (NDP1.1sp1-KB867460-X86.exe)? -- /JockeB - Developer Tag: Internet Explorer does not Fire events... Tag: 106306

    - Is it a BUG in C# compiler ?!!!! Hi All. I faced with strange behavior of C# compiler - in some cases it generates not working code! I mean code that lead to the exception - System.InvalidProgramException: Common Language Runtime detected an invalid program. The situation is following - 3rd vendor library generates a class that contains too big InitializeComponent method (copy-paste of InitializeComponent method to empty text file gives us 23.100 lines and size = 1.9mb). When calls this method is called application immediately crashed with the message - "System.InvalidProgramException: Common Language Runtime detected an invalid program." Content of InitializeComponent is similar to such methods in Windows.Forms or Asp.Net application - there are initializations of components properties ans so on - nothing special, just lot of assignments; no local variables - ony class members used. Just by a guess I tried to split up that method to more small pieces of code - InitializeComponent1, InitializeComponent2 and so on. After that mentioned error disappeared - all things begin to work fine. I tested this case on 3 different computers - this error is stable (btw, I my computer is Pentium4-3GHz/1Gb RAM/120Gb HDD, then I do not think that error could appears because of weak computer). One more case I tested - Debug and Release builds of that application - mentioned error appears constantly only in Debug build, Release build of the application works fine. And one more interesting thing - this error stable appears in VS.Net 2003 and VS.Net 2005 Beta2. Then is could be a problem of new VS.Net too. My questions are: Is it a BUG in C# compiler? Is it limitation of compiler? Where such limitations described? Should I think my conclusion about reason of this error (I mean - too many code in one class method) is correct? Or perhaps you could see any other possible reasons of the problem? Which? Could we expect Microsoft to release the patch in the nearest future? Or should we ask 3rd vendor to implement the workaround I found (I mean - splitting up big method to smaller)? The problem is very serious for us, please help! WBR, Dmitry.

    - Dumbass Dependancy Chain Hi I cant install .Net 2.0 because of an error with the Windows 3.0 Installer, this in turn means i cant install Sql Server 2005 Express Edition. Does Microsoft seriously expect that Im going to open myself up to this kind of bullshit dependancy chain for every copy of my software I sell? Not likely. Seems to me the support costs of this 2.0 model alone would eat through any profit I might make. Maybe those VB6ers do have a point. TM Tag: Internet Explorer does not Fire events... Tag: 106292

    - TextWriterTraceListener I'm using the TextWriterTraceListener that is configured via an app config file. This works great when there's only 1 instance of the applciation running. If there are more than 1, then I get an access denied because another process has the file locked. I could add the TextWriterTraceListener in code at runtime and specify a unique file name but I was hoping to keep the configuration in the app config file. What is the best way to handle using the TextWritrTraceListener in this scenario? Thanks, Eric Tag: Internet Explorer does not Fire events... Tag: 106289

    - Communication via IPC Hello, I've been reading up on IPC and looking at sample code, and I can't seem to figure out how to actually accomplish communication from a client to a server. I understand the concept of a server hosting a dll which contains a method that the client can call. However, how can the server also obtain a reference to the same object? I want the client to be able to send a message that makes it to where the server can use it. To clarify my question, the examples I've seen so far have been like this: Server creates a channel exposing Class A. Class A contains a handy-dandy method that can multiply two ints. Client creates a channel to be able to instantiate a new Class A object and call its methods. But how does Client get a message all the way back to Server? I tried creating a client channel in the server itself, but I can't make that work. I get an exception saying that there is already a registered object for that channel. I also tried creating an instance of Class A in the server, but it was a completely separate object that did not see messages that the client put into it. To give some context, I have a Windows service that needs to be controlled via a Windows Forms app. As I understand it, to get messages to the Windows service, I would create a channel there and have the Forms app be the client. But how do I actually retrieve the messages from within the service? Apparently IPC is the way to go for on-box communication, but I haven't seen any examples showing how to get a client and server to exchange actual messages. Please help!
