    - Option to Do "Quick Fix" Hi, Recently I worked on a project where we brought in a Microsoft employee to help us. He and I were trying to do a "quick fix" on a server that contained an entire dotnet application, and he showed me an option that you could put into a file (I can't remember if it was a .aspx file or a Web.config file) that would allow us to test the change without re-compiling. I can't find where I wrote down the option to use, could someone else tell me what it is? I've searched the documentation, but apparently I'm not looking in the right places. I have some vague memory of it having something to do with this line: <%@ Page language="c#" Codebehind="Console.aspx.cs" AutoEventWireup="false" Inherits="BackupConsole.WebForm1" %> Thanks, Steve Tag: .Net on NT 4.0 Tag: 68575

    - Installer - Custom Textboxes in UI problem I have added a 'Textboxes (A)' to my UI installer project along with a custom action to pass the value back to a class I've written to override the void Install function. As long as the text is very simple everything is working just fine. I've tested it by writing the string out to a text file to test it. However, the trouble comes in when I use the textbox for what I really intended, a ADO.Net Connection String. The textbox is to allow the user to put the connection string and I intend to test the db connectivity and write it to the registry during installation. However, when I enter a real connection string in the box, it chokes and gives an error -- presumably because of either the semicolon, space, or equals characters in it. Is there a list of characters that can't be input? Do I need to escape them somehow before passing them? (notice the beginning of the exception message is _PART_ of my connection string, it's trying to parse that string into multiple context parameters I think). I get the following error Exception occured while initializing the installation: System.ArgumentException: File Source=workstation;Initial does not exist. If this parameter is used as an installer option, the format must be /key=[value].. (OK Button) Again, everything works when the string is simple, so I'm sure I'm passing it OK. Just to provide all the info - I've named the Edit1Property to 'CONNSTRING' and the custom action 'CustomActionData' is /connString=[CONNSTRING]. The exact string I input in the box and overridden install function is below: String Input: Data Source=workstation;Initial Catalog=serverPerformance;User ID=serverPerformance;Password=server; My install function: [RunInstaller(true)] public class ProjectInstaller : System.Configuration.Install.Installer { public override void Install(IDictionary state) { string connString = this.Context.Parameters["connString"]; if(connString == "") { throw new InstallException("The database conection information is not optional. Please obtain this information from your system administrator and run setup again."); } System.Data.SqlClient.SqlConnection myConn = new SqlConnection(); try { string queryCount = "SELECT count(*) FROM sysobjects WHERE name like 'sample%' AND xtype = 'u'"; myConn = new System.Data.SqlClient.SqlConnection(connString); System.Data.SqlClient.SqlCommand cmdCount = new System.Data.SqlClient.SqlCommand(queryCount,myConn); myConn.Open(); int tableCount = (int) cmdCount.ExecuteScalar(); if (tableCount<2) { throw new InstallException("The connection to the database was made successfully, but the correct database structure doesn't exist. Please use a different database or refer to the documentation to build the database structure and then reinstall this service."); } } catch (System.ArgumentException argEx) { throw new InstallException("Error validating provided SQL connection string. Please check your connection string and run setup again.\r\n\r\nError: " +argEx.Message); } catch (System.Data.SqlClient.SqlException sqlEx) { throw new InstallException("Error connecting to database and executing a query to test the database availability and structure. Please check your connection string and and database server and run setup again.\r\n\r\nError: " +sqlEx.Message); } catch (Exception ex) { throw new InstallException("There was an error attempting to validate your connection string and database structure. Please check your connection string and database server and run setup again.\r\n\r\nError: " +ex.Message); } finally { if (myConn.State != ConnectionState.Closed) myConn.Close(); } } } Tag: .Net on NT 4.0 Tag: 68570

    - Framework Won't Uninstall Hi all- I cannot get the .NET Framework SP2 to install, so I thought I would uninstall and start over. However the uninstall fails with the message "Microsoft .NET Framework Setup has failed. If this continues, please contact Product Support." I tried using the command line: n:\<Installation Source>\dotnetfx.exe /t:%temp% /c:"msiexec.exe /fvecms %temp%\netfx.msi" to repair the installation, but that isn't working either. Does anyone have any ideas, or know how to manually uninstall the Framework? Thanks in advance, Kendra Tag: .Net on NT 4.0 Tag: 68553

    - Creating publisher policies for DLLs We have a .NET dll that we are deploying to our customers using a deployment project in VS .NET 2003. There is a lot of information about creating publisher policies on the web, but we have not been successful in creating one. Here's what the ultimate goal is: When the DLL is deployed to a customer's system, every application using this dll must point to the new version. This has to be an automated process using the deployment project. This is what we have already done: 1. Created a file called app.config with the following text: <configuration> <runtime> <assemblyBinding> <dependentAssembly> <assemblyIdentity name="name of assembly" publicKeyToken="public key token" culture="en-us"/> <bindingRedirect oldVersion="1.0.0.0-65535.35535.65535.65535" newVersion="2.0.1.0"/> <codeBase version="2.0.0.0" href="http://www.foo.com/bar.dll"/> </dependentAssembly> </assemblyBinding> </runtime> </configuration> We copied this from a howto on gotdotnet.com 2. We signed the dll with our key and created a policy file. 3. We then deployed this dll to the customer's GAC. However, the customer's application that used an old version of the dll did not automatically redirect to the new version. Is there something we are missing? Does the name of the config file have to be something specific (like myassembly.dll.config)? Has anybody ever gotten this to work? Any help would be appreciated, Thanks, MT Tag: .Net on NT 4.0 Tag: 68541

    - MS Outlook automation from .NET Windows Service Hi, All! I seem to be having something of an Outlook automation problem, and if you guys could please be bothered to take a look at the following snippet of C# code: static void TestOutlookAutomation() { System.Diagnostics.EventLog tmpEventLog = new EventLog("Application"); tmpEventLog.Source = "Test Outlook Automation Client"; try { tmpEventLog.WriteEntry("Starting Outlook Automation", EventLogEntryType.Information); Outlook.Application olApp = new Outlook.ApplicationClass(); Outlook.NameSpace olNs = olApp.GetNamespace("MAPI"); for (int k=1; k<=olNs.Folders.Count; k++) { Outlook.MAPIFolder folder = olNs.Folders.Item(k); printFolderInfo(folder, 0); } } catch(System.Exception eX) { string msg = ""; System.Exception traceEx = eX; while (traceEx!= null) { msg += traceEx.GetType().ToString() + ": " + traceEx.Message + "\n"; traceEx = traceEx.InnerException; } tmpEventLog.WriteEntry(msg, EventLogEntryType.Error); } } public static void printFolderInfo(Outlook.MAPIFolder folder, int level) { string tabs = ""; for (int i=0;i< level; i++) { tabs += "---"; } System.Diagnostics.EventLog tmpEventLog = new EventLog("Application"); tmpEventLog.Source = "Test Outlook Automation Client"; tmpEventLog.WriteEntry(tabs + folder.Name + "\t(" + folder.Items.Count + ")", EventLogEntryType.Information); for (int j = 1; j < folder.Folders.Count; j++) { printFolderInfo(folder.Folders.Item(j), level + 1); } } For testing purposes I've wrapped these two methods inside a) a Windows Service Project, and b) a standard Windows Application Projects, built them and deployed the assemblies on two different computers - both having MS Outlook installed, both running Windows 2000 OS -. However, on computer1 the Windows Service, as well as the standard Windows App, runs smoothly. On computer2, on the other hand, the Windows App reads the mailfolder info with no problem whatsoever, but the execution of the Windows Service results in a System.Runtime.InteropServices.ComException error message being written to the eventlog. This, despite the fact that the owner of the process in which the Windows Service and the standard Windows App executes on computer2, is the exact same Windows user profile. Any advice on this issue would be highly appreciated. Regards, Trond Tag: .Net on NT 4.0 Tag: 68536

    - .Net ViewState toggle causing Smurf Attack in routers ? Our .NET web application was getting blocked in several routers (DLink) as a "Smurf Attack" (a faked sender IP address). This was systematically happening in the transfer between the first and the second page on our web site After much ado we found out that turning off client viewstate (in the Aspx page) caused the problem to go away; or so we thought. it turns out we only moved the problem a couple of pages later in the system, but this time it was a HttpHandler that was being blocked (no Aspx involved) Before we got the second bug report, I thought this problem was related to the actual _VIEWSTATE HTML hidden field that was being sent. When the second problem was reported, I am more inclined to believe that the ViewState toggle (in the Aspx) has some side-effect on Socket Pooling in IIS/.NET. Between the two page requests, there is idle time on the socket (obviously, we are waiting for user action); could the Smurf Attack be triggered by a change of socket for the next request ? Anyone have any experience on this Kristia Tag: .Net on NT 4.0 Tag: 68529

    - Byte array to string and back - newbie question Hi, I am trying to implement DES algorithm as described in the Microsoft article at http://msdn.microsoft.com/library/en-us/dnnetsec/html/SecNetHT10.asp. The problem is that I need to save the data in the database as String, and for that I have to convet from Byte array to string and back. When I cast a byte array into a string and then back to a byte array, I don't get the same array. For example: Dim SecretText As Byte() Dim SecretText1 As Byte() Dim Text as string ..... SecretText = enc.Encrypt(Data, Key, Vector) 'returns Byte Array Text = Encoding.ASCII.GetString(SecretText) 'convert to string in order to save into the DB .... .... .... SecretText1 = Encoding.ASCII.GetBytes(Text) 'prepare for decryption routine At the end, SecretText1 does NOT equal to SecretText, and I want it to be. How should I do the conversion correctly?

    - MSN Presence info Originally posted to microsoft.public.dotnet.framework.aspnet with no viable responses: 1st, if this is the wrong group, let me know... my local server doesn't carry the full feed from MS. After spending about 2 hours searching (google, codeproject, sourceforge.. etc), I've not been able to find an example of code that will allow you to publish your MSN status. I did find some older examples, but apparently there have been some changes in protocol and they are no longer valid. Does anyone know how to go about doing this, or have a link to somewhere that does? I did find an article that went into a little detail about the protocol, but it was more geared towards "this is how you sign on and send a message". I even started scouring MS for some kind of SDK (Although by the time I thought of that my brain was starting to hurt). One would think that MS would supply a simple URL as some of the other messenger services do.. but I can also see the cost of doing that in server usage and bandwidth. I guess the only way would be to develop a control that pretends to be a client and check that way.... sheesh. Tag: .Net on NT 4.0 Tag: 68518

    - TURN $12 INTO $12,000 NOW!!! EEP THIS SHIT YALL MY FRIEND GOT $500 LAST WEEK TRYING THIS SHIT: make extra cash GREAT WAY TO BECOME RICH...INSTANT THOUSANDS This is no scam, read it!!!!!! ------------------------------------------------------------------------ -------- HOW TO TURN $12 INTO $12,000!!!!!!!!!!!!!!!!!!!!!!!!!!!! THIS REALLY CAN MAKE YOU EASY MONEY!! IT WORKS !!! BUT YOU HAVE TO FOLLOW IT TO THE LETTER FOR IT TO WORK!!!! : A little while back, I was browsing through newsgroup, just like you are now and came across an article similar to this that said you could make thousands dollars within weeks with only an initial investment of $12.00! So I thought, "Yeah, right, this must be a scam", but like most of us, I was curious, so I kept reading. : Anyway, it said that you send $2.00 to each of the 6 names and address stated in the article. You then place your own name and address in the bottom of the list at #6, and post the article in at least 200 newsgroup. (There are thousands) No catch, that was it. So after thinking it over, and talking to few people first, I thought about trying it. I figured what have I got to lose except 6 stamps and $12.00, right? Like most of us I was a little skeptical and a little worried about the legal aspects of it : All, So I checked it out with the U.S. Post Office (1-800-725-2161) and they confirmed that it is indeed legal! Then I invested the measly $12.00. Well GUESS WHAT!!?. Within 7 days, I started getting money in the mail! I was shocked! I figured it would end soon, but the money just kept coming in. In my first week, I made about $25.00. By the end second week I had made a total over $1,000.00! In the third week I had over $10,000.00 and it's still growing. This is now my fourth week and I have made a total of just over $42,000.00 and it's still coming in rapidly. Its : Certainly worth $12.00, and 6 stamps, I have spent more than that on the lottery!! : Let me tell you how this works and most importantly, why it works?.also, make sure you print a copy of this article NOW, so you can get the information off of it as you need it. STEP 1: Get 6 separate pieces of paper and write the following on each piece of paper "PLEASE PUT ME ON YOUR MAILING LIST." Now get 2 US $1.00 bills and place TWO inside EACH of the 6 pieces of paper so the bills will not be seen through the envelope to prevent thievery. Next, place one paper in each stating the above phrase, your name and address, and 2 $1.00 bills. What you are doing is creating a service by this. THIS IS ABSOLUTELY LEGAL! Mail the 6 envelopes to the following addresses: #1) Corteney Tomson P.O. Box 55 Dupo, IL 62239 #2) Brad Taylor 6 Terry Ln. Hutchinson, KS 67501 #3) Cedric Etienne 239 Autumn Breeze Way Winter Park, FL 32792 #4) Stephen Mitchell 1977 Alcovy Trace Way Lawrenceville, GA 30045 #5) Melissa Martinez 15440 sw 74 cir ct #607 Miami, FL 33193 #6) Maurice Sawyers 49 Middle Rose St Trenton, NJ 08618 STEP 2: Now take the #1 name off the list that you see above, move the other names up (6 becomes 5, 5 becomes 4, etc?.) and add YOUR Name as number 6 on the list. STEP 3: Change anything you need to, but try to keep this article as close to original as possible. Now, post your amended article to at least 200 newsgroups, message board. (I think there are close to 24,000 groups) All you need is 200, but remember, the more you post, the more money you make!---- DIRECTIONS----HOW TO POST TO NEWSGROUPS, MESSAGE BOARD----------Step 1) You do not need to re-type this entire letter to do your own posting. Simply put your cursor at the beginning of this letter and drag your : Cursor to the bottom of this document, and select 'copy' from the edit menu. This will copy the entire letter into the computer memory. Step 2) Open a blank 'notepad' file and place your cursor at the top of the blank page. From the 'edit' menu select 'paste'. This will paste a copy of the letter into notepad so that you can add your name to the list. Step 3) save your new notepad file as a .txt file. If you want to do your postings in different sittings, you'll always have this file to go back to. : Step 4) Use Netscape or Internet explorer and try searching for various newsgroups (on-line forums, message boards, chat sites, discussions.) Just example you log on any search engine like yahoo. com,google. com,altavista. com,excite. com then you search with this subject ? millionaire message board? or ?money making message board? or ? employment message board? or ?money making discussions? or ?money making forum? or ?business message board? etc. You will find thousand & thousand message board. Click one by one then you will find the option post a new message. : Step 5) Visit these message boards and post this article as a new message by highlighting the text of this letter and selecting paste from the edit menu. Fill in the Subject, this will be the header that everyone sees as they scroll through the list of postings in a particular group, click the post message button. You're done with your first one!. : Congratulations? THAT'S IT! All you have to do is jump to different newsgroups and post away, after you get the hang of it, and it will take about 30 seconds for each newsgroup! ** REMEMBER, THE MORE NEWSGROUPS OR MESSAGE BOARD YOU POST IN, THE MORE MONEY YOU EILL MAKE!! BUT YOU HAVE TO POST A MINIMUM OF 200** That's it! You will begin receiving money from around the world within days! You may eventually can rent a P.O. Box due to the large amount of mail you will receive. If you wish to stay anonymous, you can invent a name to use, as long as the postman will deliver it. **JUST MAKE SURE ALL THE ADDRESSES ARE CORRECT. ** : Now the WHY part: Out of 200 postings, say I receive only 5 replies (a very low example). So then I Made $5.00 with my name at #6 on the letter. Now, each of the 5 persons who just sent me $2.00 make the MINIMUM 200 postings, each with my name at #5 and only 5 persons respond to each of the original 5, that is another $25.00 for me, now those 25 each make 200 MINIMUM posts with my name at #4 and only 5 replies each, I will bring in an additional :$125.00! Now, those 125 persons turn around and post the MINIMUM 200 with my name at #3 and only receive 5 replies each, I will make an additional $625.00! OK, now here is the fun part, each of those 625 persons post a MINIMUM 200 letters with my name at #2 and they only receive 5 replies, that just made me $3,125.00!!! Those 3,125 persons will all deliver this message to 200 newsgroups with my name at #1 and if still 5 persons per 200 newsgroups react I will receive $15,625.00! With an original investment of only $12.00! AMAZING! When your name is no longer on the list, you just take latest posting in the newsgroups, and send out another $12.00 to names on the list, putting your name at number 6 again. And start posting again. The thing to remember is, do you realize that thousands of people all over the world are joining the internet and reading these articles everyday, JUST LIKE YOU are now!! So can you afford $12.. and see if it really works?? I think so? People have said, 'what if the plan is played out and no one sends you: the money? So what are the chances of that happening when there are tons of new honest users and new honest people who are joining the internet and newsgroups everyday and are willing to give it a try? Estimates are at 20,000 to 50,000 new users, every day, with thousands of those joining the actual Internet. AND YES YOU HAVE TO SEND THE MONEY FOR THIS TO WORK!!!dont try not to,IT WONT WORK TRUST ME Tag: .Net on NT 4.0 Tag: 68515

    - Slow TCP connection from IE I have a problem with TCP connections from controls embedded in HTML pages. The client-application is a (.NET) usercontrol embedded in an HTML page (viewed using IE). When the client calls: Dim client As New System.Net.Sockets.TcpClient(_hostname, _port) while at the same time the server calls: i = stream.Read(bytes, 0, bytes.Length) it takes _exactly_ 100 seconds the first time â?? subsequent calls are immediate. It looks like itâ??s a timeout â?? but of what?!? â?? after all: I get the correct result; no problem there. Using TDImon fra SysInternals I can se that at the first (and very slow) communication, IE initially communicates at port 80 - but I havn't got a clue why. I have wondered whether it could be a DNS error, but the host I communicate to is localhost so I think that would be a rather strange reason. The problem has been verified in different organisations using several independently installed PC's. When the client control is placed in a winform instead of in a HTML page, there is no performance problem at all. I have a small, clean and to the point VS-solution which demonstrates the problem if anybody is interested. It consists of the control project, a winforms client, a html page and a tcp-server project. I am sure that this is expected behaviour â?? just no for me or anyone that has looked at itâ?¦ ;^( Regards Henrik Tag: .Net on NT 4.0 Tag: 68509

    - Mutex and WAIT_ABANDONED .Net's Mutex object seems to ignore (or internally consume) a WAIT_ABANDONED condition if the owning thread is aborted. The next thread waiting on the Mutex gets the mutex with no error. If this is by design, it would seem to be a dangerous design choice. Normally another thread would want to know this information as the thing the mutex was protecting could (and probably is) be in an inconsistant state, yet the 2nd thread will march on like nothing was wrong.

    - .NET application memory usage Has anyone encountered a situation where a .NET(VB.NET) application uses a lot more RAM on one machine than it does on another machine? On an machine with XP Pro, .NET Framework 1.1 & all the latest patches my program uses 45MB of physical RAM and 85MB of virtual memory. This is a LOT for what this application does. On another machine with Windows 2000 Server, .NET Framework 1.1 & all fixes, the exact same build of the program uses only 16MB of physical RAM and only 8MB of virtual memory. Simlilarily, on another XP Pro machine the same build of the program uses about the same 16MB of ram and the same amount of VRAM. Both XP machines have Visual Studio .NET 2003 installed, and the 2000 Server doesn't, so this can't be a debug version of the runtime(if there is such a thing) causing it to use so much RAM. The program is compiled as release by the computer using so much RAM in all test runs on each machine. So... What's going on that causes it to use so much memory on the one machine but not the other machines? Thanks, Devon. Tag: .Net on NT 4.0 Tag: 68505

    - How to trigger IDE code generation? Hello all I am writing a custom formatter to serialize controls to a text file. It largely works (at least I keep thinking that) My current problem is that when a form is deserialized in the designer, the screen is updated properly and the properties show correctly in the editor window, but the newly altered properties do not persist into code. Usually I need to make a slight modification to the objects (e.g. select and move them) for the alterations to persist I am wondering is there a simple call which will cause the IDE to initiate serialization to code? I suspect I need to somehow get a hold of the IDE's IDesignerSerializationManager object and through it obtain the necessary serializer for my root object and then serialize it - but how do I do that Thanks for all replies Marku Tag: .Net on NT 4.0 Tag: 68504

    - Image->Bitmap->Icon transparency problem Hi, I'm loading an Icon from a Stream and want to save it to file. I've realized that in order to avoid a bug in the framework I need to do something like this: Bitmap bmp = new Bitmap(m_Img); IntPtr hdl = bmp.GetHicon(); Icon icn = Icon.FromHandle(hdl); using (FileStream fs = new FileStream(name, System.IO.FileMode.Create)) { icn.Save(fs); } DestroyIcon(hdl); That works fine, kinda... During the conversions I loose the transparency of the original Icon; ie. the saved icons will have black backgrounds instead of transparent backgrounds. Any workaround? (apart from doing it all through API-calls to GDI+) Any official acknowledgement from MS about the bug? (a link perhaps) Any ideas if or when it'll be fixed?

    - embedded winforms in IE wont cache I have a problem. The issue is that my embedded winforms in IE will not cache no matter how hard i try. They seem to goto the download assembly cache but they dont load from there like the framework documentation has stated. I have tried versioning, strong naming, and everything else i can think of. Any response, esspecially from MS would be great! I would like to know if this is a bug that is expected to be fixed in the .NetFramework, or is there a work around till the bug gets fixed. Thanks!!!!! :) Here is some of the previous posting that i had made, followed by MS Response ****: Hi Bryan, It's really good to hear someone having the same problem (sorry to say) - precisely the same problem is KILLING my released application stone dead because of performance issues over low bandwidth connections. I AGREE, the controls are NOT being loaded from the download cache when available, and the documentation (I am certain) INCORRECTLY says this will happen. I have based many months of development based on this concept, believing the documentation and suspecting it is me misreading the signs or doing something wrong. I now no longer believe this to be the case. Can someone out there at Microsoft help? This is a real cry for help you're hearing here. Why are IE hosted controls not being loaded from the download cache when no newer versions are available on the server? Please find attached similar posting (unanswered) from myself on the sister windowsforms.controls newsgroup: Subject: IE hosted control and the download cache 1/16/2004 3:47 AM PST Hi, Should my IE hosted Windows Control be invoked from the download cache after it's first use? It appears that my Windows Control is being downloaded every time from the Web Server. My understanding is that every time a Windows Control is invoked from within an HTML <Object> tag, that the CLR first checks on the server to see if there is a new version of the assembly is available. If there is not, then the last downloaded assembly will be invoked from the download cache, if one exists. However, it appears that my control is being download every time, and as available bandwidth narrows, the control takes a REALLY long time to download/invoke, even though I told my managers (perhaps mistakenly!) that they will only experience this the first time they invoke a new version of the component from the web server. I had read that there may be a connection between strong naming an assembly and the download cache, so that versioning can work correctly, however I've just added a stong name to my assembly (by adding [assembly: AssemblyKeyFile(@"....snk")] to AssemblyInfo.cs) but it appears to have made no difference. Should I be doing more to get my control invoked from a users download cache whenever possible? Many thanks, Richard Sheridan ----- bryan wrote: ----- The problem is that when we embed a usercontrol in a html page the control is noty cached on the client as specified by numerous MSDN articles.

    - Invoke fails in control class Hi! I've taken the Pocket signature sample from http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnnetcomp/html/PPCSignatureApp.asp and modified the client socket to run as a single class without a form. I just derived the class from "forms.control" and it works perfect with compact framework. Now I tried to use the class with the full framework. When I call Me.Invoke I get the famous error "Cannot call Invoke or InvokeAsync on a control until the window handle has been created". If I copy that part of code back to a form generated by the form designer, everything works fine. Trying to expand my class to be a form failed. Does anyone know what I have to do to get it to work in a control class? Thanks in advance! Benjamin Lukner Tag: .Net on NT 4.0 Tag: 68455

    - show a new control outside of its parent I am programming a control for the CF, and i need to make something like the ComboBox enroll behavior. If you click on it. it should enroll another item, for example a picturebox. To enroll it down, it could be possible to define the picture box inside the control, and on cliking the control to change its clientsize to make the picturebox visible. But if the control shall enroll it to the top, because its on the bottom of the form, I would have to change its location and the size. the original combobox shows the new item, without changing its size and location. So my question is how to show a new control outside of its parent ? somebody knows help ? THX Milosz www.playseven.com Tag: .Net on NT 4.0 Tag: 68447

    - New MS Authorization and Profiler Application Block fits only for small applications and examples!! Hi to all .NET gurus, we evaluated the new Application Block "Authorization and Profiler Application Block" for using with role based authorization. Our results: - No roles in roles can be managed (that is a must in a role based system) - In every check there is no caching between them (performance sucks) - Dynamic object creation in every access (performance sucks) - Profiles and Principals must be handled completely seperated (??) - In every access check you have to build up parameters etc - this handling is unbelievable overhead!! - You have to cast the principal for every access (you better use a gerneric class with static helpers here!) So the result is: Use it to play a bit and use it for very small example applications. It is a good example for newbies out there - and the pluggable system in this block was a good idea (not new but fine)! I work for companies like BASF, DaimlerChrysler, BMW etc. and i have implemented some role based access systems before in .NET - but this block doesn't fit for them. I can't understand why they did not optimize it - other blocks have caching etc. in it? You can implement own providers etc. but thats somewhat dumb that you better build up your own system with caching, expirations etc... Let me know if there are questions - i develop open source software and im .NET consultant for different companies out there. Greetings and happy programming Ralf Tag: .Net on NT 4.0 Tag: 68439

    - Getting error AL1057 at linkage time?? Hi everybody! I have a Managed C++ application that I have localized with one extra language apart from the default language. The program now handles culture neutral languages Swedish (default) and English. This is a customized installation tool, so the default is to install things. Localization for that functionality are handled by the Forms own embedded localization. For the Uninstallation functionality I have added 2 resource files (Assembly Resource .resx) named Tool.en.resx and Tool.resx to handle all messages when the uninstall is run. It works fine!! Now to the problem!! When I have updated the text strings in these to extra resource files, I get the error from the Assembly Linker: AL1057 Executables cannot be localized, Culture should always be empty The first time the linker fails to link my program, the second time it links and can be executed. It also runs without any problems, so why this error!! Whats the problem??? /Thanks Tag: .Net on NT 4.0 Tag: 68436

Yes, .Net 1.0 and 1.1 support NT 4.0, however the upcoming Whidbey release will no longer be supporting NT4.
