 - DRAWIMAGE() -> TONS OF PAGE FAULTS! Originally, I thought this was due to DoubleBuffer, but ran some further experiments and discovered that page faults occur when calling DrawImage(). For example, create 2 images about 800x800, then call DrawImage to copy from to the other (on say a mouse click). Notice about 600+ page faults occur each time (the larger the area, the greater the number of page faults). I have an application that calls DrawImage() once a second to update the main screen, so after a few days, the page fault count is monsterous. I swear this bogs down my system too. Anyone else have this problem? Any solutions? Can someone report this as a DEFECT. Thanks, Steve Tag: N Tier Architecture ? Tag: 101175

 - How To: Custom Performance Counters with intervals other than 1 second? I want to implement a custom performance counter for monitoring errors in my application. However, the correct rate is not exceptions per second! (If my app is throwing multiple exceptions per second, then the last thing I need to be doing is writing custom performance counters!) I want to implement a counter that has a period of 1 hour. What is the right way (or best way) to do this? I figure out one way, but I had to implement all the code and not use any of the methods in the Diagnostics namespace (other than just setting the raw value of my counter). I don't think that is the right way to do it. Although all the framework code seems to assume periodicity of 1 sec, I have a feeling I should be able to use the framework methods and obtain rates per hour -- I just need some help figuring out the way to go about it.

 - HttpWebRequest and Multi Threaded apps Question Hi, Im in the process of writing a program that crawls a website. Im using the HttpWebRequest and HttpWebResponse classed to get content. To make my application more scalable, my application is multithreaded, with each thread making a different request. One problem Ive ran into is that when writing the response stream to the filesystem, from the HttpWebResponse.GetResponseStream() method, if the response is of a sufficient size, it blocks all other other executing threads. If this exceeds the timeout, then all the other threads that are in the process of making a Web Request time out. Ive taken every effort to ensure that my application is not locking, I was wondering if given the scenario that Ive listed, would using Asynchronous Web Requests be more efficient? Ive not worked with them before so Id be grateful of your opinions. Cheers, Mark Tag: N Tier Architecture ? Tag: 101168

 - Convert BinaryString into int? Hello, I have some binarystrings in the registry (from an older j++ app) that I need to convert at runtime to ints. What is the best practice for this? In J++ you could just call Integer.ParseInt(val, 2); I've tried Convert.ToUInt32(object, int) but I can't get the compiler to believe that is a valid overload; it keeps complaining that it can't convert an int to an IFormatProvider, which is a different overload. Is that convert function broken? Is there another way to do this or am I just screwed? Keith Tag: N Tier Architecture ? Tag: 101160

 - Issue with MMC in VS.NET Dear all, I am facing a frustrating problem in trying to make sense of an existing MMC Snapin developed using Visual Studio .NET by You-Know-Who. Well, the project type for the Snapin is a Class Library. Once I build the solution from visual Studio .NET, the solution consisting of the Class Library and the Packager, will churn out a .MSC file.. All this is working fine.. I am supposed to enhance this project and I must add that I have no prior experience in developing or debugging MMC Snapins in .NET. Since I have not developed this project, I have really no clue as to how to go about getting into a debug environment for this project. Can anyone please help?? An attempt to debug would say that the project is of class library type and therefore cannot be debugged directly.... I need to be able to debug to make sense of how this one works... Any help would be really appreciated.. Thanks and regards, Varkey Tag: N Tier Architecture ? Tag: 101154

 - Java Null VS .NET Null In Java, creating a class that represents a tuple in a database is relatively simple because if you have a field for, lets say, "Quantity" that is an integer, you can set it to null. Since .NET uses a stack for these Value Types, the integer (Int32) has an initial value of 0 and you can't set it to null. So, what's the best way to approach this without having to jump through a bunch of programmatic hoops? These are a couple of ways I've though of. 1) Create a constant that represents a null Int32, et and use that value (problem: you'd have to constantly check that value if you're doing calculations) 2) Make all of your properties be objects. That way you could set the property to an integer, or a null (or DBNull.Value). (problem: performance hit from boxing and potential errors when doing calculations) 3) Have a property for the field and then have an ancillary property names "FieldXIsNull" (problem: classes get bulky and you end up having to check the IsNull constantly) So, what are the best ways to approach this? Side Note, I'd like to stay away from using datasets because they're big memory hogs. If I can have a class that I can instantiate that keeps track of real values, I'll get better memory usage. As far as the overhead of coding all of these classes, I can use/create code generators for that. Tag: N Tier Architecture ? Tag: 101152

 - MyClass2 = MyClass1 -> ByRef???? Hi, I have 2 instances of a user-defined class. When I do a cls2 = cls1, and I change a property of cls2, this property is also changed in my cls1!! Does anybody know what the reason of this is? and how I can prevent it? Thanks, Pieter I'm using VB.NET 2003.

 - Port .Net 1.0 application to Windows Server 2003 Hi, We have a complex application (C#, EnterpriseServices (COM+), MSMQ, etc). Application was developed with .Net Framework 1.0 and running on Windows 2000 with SP3. We need to port it to Windows 2003. By default, Windows 2003 has .Net Framework 1.1 installed. Initiall we were planning an application upgrade to 1.1. But later decided to try to install .Net Framework 1.0 on Windows 2003 server and try to port it the way it is now. Is it doable? I don't see why not. I was reading different sources and I didn't find any reasonings why not. Can you let me know, please. Second issue for the same problem: an applicaiton server, that is going to be running a COM+ components is like I said Windows 2003. I installed a component on it, extracted a proxy and installed that proxy to the test machine from which I tried to run a strip-down version of the same application (only test machine issies calls to the database thru COM= component.). I receive the following error message: The activation for CLSID {070CE8EA-70F6-4E7C-8E73-A902507E811F} failed because remote activations for COM+ are disabled. To enable this functionality use the Configure Your Server wizard and select the Web Application Server role. The application is desctop, no web interface. Why does it need to be configured for the Web Application Server role? Is it a Windows 2003 issue? We prepared the server just as we did before with Windows 2000. Any input is welcome.

When I call the BeginConnect method, if the remote endpoint does not exist, it waits something like 20 seconds before returning an exception.

 - Centralizing the Authentication Process Hello Friends, Our department has created a few (6) Web Applications and all these applications share a common piece of code which does the "User Authentication". I would like to isolate the authentication process. I am thinking of having a common/central server which gets all authentication requests and creates a valid session for all users who have successfuly logged in. If an unauthenticated user tires to access these application then he/she should be redirected to the login page on this central server. This will help me reduce the time required for maintenance and deployment. How should i go about achieveing this. Is there an article or any documentation on this Is there a server which could help me achieve this. Any help/guidance will be greatly appreciated. Thanks, Mohit Tag: N Tier Architecture ?

 - Accessing Process.ProcessName starts continuous I/O activity I am seeing something unexpected when accessing the Process.ProcessName property. Immediately after accessing it, my process starts continuous I/O activity at a rate of 10 reads/sec and 5 writes/sec. My process is not doing anything else at the time - it is a long running process that sits idle most of the time except for this constant I/O activity. This is happening on WinXP Pro + SP2 and Win2003 + SP1, both running .NET 1.1 + SP1. Any ideas how to quiet things down after accessing the ProcessName? It continues even after the var that uses it goes out of scope. Here is a simple program to demonstrate this: using System; using System.Diagnostics; namespace ProcessNameTest { class ProcessNameTest { [STAThread] static void Main(string[] args) { string dummy; Process currentProcess = Process.GetCurrentProcess(); System.Console.WriteLine("Check this processes I/O activity now - should be no new I/O"); System.Console.WriteLine("Hit Enter to continue"); dummy = System.Console.ReadLine(); string process = currentProcess.ProcessName; System.Console.WriteLine("Check this processes I/O activity now - should be about 10 reads/second and 5 writes/second"); System.Console.WriteLine("Hit Enter to continue"); dummy = System.Console.ReadLine(); string processUpper = process.ToUpper(); string pid = currentProcess.Id.ToString(); } } } Tag: N Tier Architecture ?

 - A namespace implemented over several different assemblies? Hi all, Can anyone tell me if it is advisable (or even possible) to define a namespace across 2 or more assemblies? For example, consider the namespace SampleApplication.Data.Providers Would it be possible to have assembly A define a class as part of that namespace as well as Assembly B also declaring a class to be within it as well? In particular, I have a number of data providers. It would be useful (I think) to declare them in the same namespace, but for the purposes of a demonstration I'm doing, each provider must exisit in its own seperately deployed assembly. Is this possible and is it a good idea? Thanks to anyone who can share some advice! :-) Kindest Regards tce Tag: N Tier Architecture ? Tag: 101077

Dim Data As String = "fileCountThreshold=10, fileSizeThreshold=512, foldername=C:\logs\, " & _ "fileSizeUnit=kilobytes, fileAgeThreshold=1, fileAgeUnit=months, addMethod=true, " & _ "addPidTid=false, fileNameTemplate='console-{1:MMM-yy}-{0:0000}.log'" Dim defaultValue As Boolean = False Dim m As Match = Regex.Match(Data, "(?<=addPidTid=)false|true", RegexOptions.IgnoreCase) If m.Success Then Debug.WriteLine(Boolean.Parse(m.Value)) Else Debug.WriteLine(defaultValue) End If The m value returns the fact that it was successful in finding the value and it indicates that the value found is true. However the value is true for the addMethod part of the data. Other values include: m.Index = 141 (which points to the first true in the line) m.Length = 4 m.Captures.Count=1 If I put this into the code (following the first check) Dim m1 As Match = Regex.Match(Data, "(?<=fileAgeThreshold=('|"")*)[^'"",]+", RegexOptions.IgnoreCase) If m1.Success Then Debug.WriteLine(m1.Value) Else '-- check for the ='' ="" =, case (empty string) If Regex.IsMatch(Data, Name & "=['"",]['""]*", RegexOptions.IgnoreCase) Then Debug.WriteLine("") Else Debug.WriteLine(sdefault) End If End If It correctly finds the value 1. Any help would be appreciated. Tag: N Tier Architecture ? Tag: 101075

 - DotNET Generated TIF Images Won't Work With FAX Server If I use the System.Drawing Image object to save an image in TIFF format I am unable to use the FAXCOMLib to submit it to a FAX server. When doing a FAXCOMLib.FaxDoc. Send call it throws an exception with "Data is invalid". The TIF files are valid and I can open them with a document viewer. And I can submit TIFs that were generated outside of DotNET. It is only dotNET generated images that fail. Is there something different about how dotNET generates TIF images? This isn't very easy to nail down since the reason why the image is invalid isn't reported. Thanks, Bob Herzberg Tag: N Tier Architecture ? Tag: 101072

 - Delete elements in .NET collections A common issue that I see in the microsoft.public.dotnet.framework.adonet group is that if you want to delete a DataRow from a collection of DataRows (e.g. myTable.Rows), you can't do this using a foreach loop like this: foreach(DataRow row in myTbl.Rows) if(someCondition) row.Delete(); You must instead use a regular for loop and loop from back to front like this: for(int i = myTbl.Rows.Count - 1; i >= 0; i--) if(someCondition) myTbl.Rows[i].Delete(); I understand why you must do this. My question is whether this is a standard situation in .NET collection classes. I have an XML file that I'm processing using the DOM classes (XmlDocument, XmlNode, etc.) and I need to loop through the children of an XmlNode and call a function on each one that may or may not delete that child. Of course, if I use a foreach loop or a for loop that loops from front to back, the loop counter gets messed up when I delete a node. It seems to work when I use the same solution as listed above with the DataRows, but I wanted to confirm that it was a valid solution in this case. I can't find any Microsoft documentation regarding this so I was hoping somebody would be able to point me to some or maybe there would be somebody with some "inside" knowledge about this issue.

 - Log4net trouble Hi, anyone can help with log4net? i'm not sure i understand log4net object model properly... i'm trying to configure log4net programmatically, in order to assign different custom appenders to some custom loggers (run-time) and (i think) i've been able to add new custom loggers to the root logger of the repository. i've also added one appender for each custom logger. this is the code snippet i wrote: ------------------------------=AD--------------------------- log4net.Repository.Hierarchy.H=ADierarchy hier =3D (log4net.Repository.Hierarchy.=ADHierarchy)log4net.LogManager.G=ADetReposit= ory(); //customizing server logger(s) log4net.Repository.Hierarchy.L=ADogger ServerLogger =3D null; ServerLogger =3D hier.LoggerFactory.CreateLogge=ADr("ServerLogger"); ServerLogger.Level =3D log4net.Core.Level.Info; ServerLogger.AddAppender(Creat=ADeTextBoxAppender()); //add textbox appender //customizing client logger(s) log4net.Repository.Hierarchy.L=ADogger ClientLogger =3D null; ClientLogger =3D hier.LoggerFactory.CreateLogge=ADr("ClientLogger"); ClientLogger.Level =3D log4net.Core.Level.Info; ClientLogger.AddAppender(Creat=ADeTextWriterAppender()); //add textwriter appender hier.Configured =3D true; LogManager.GetRepository().Con=ADfigured =3D true; XmlConfigurator.ConfigureAndWa=ADtch(LogManager.GetRepository()=AD, new FileInfo(filename)); //filename =3D App.config file path ------------------------------=AD--------------------------- now, when i try to retrieve the custom logger i have just created using LogManager.GetRepository().Get=ADLogger("ServerLogger") or hier.GetLogger("ServerLogger") log4net create a new Logger instance named "ServerLogger" as well, without any appenders. why? how if i need to use my custom logger inside any class of my application?=20 thanks in advice=20 J=2E Tag: N Tier Architecture ?

 - File System Watcher behaviour I would use the filesystemwatcher to trap files changes into a specific directory. I take a look on the possible message, and 'cause I need to know only when a files finishede to have been copy, I user the LastAccess message. I do a simple project, and there all works fine. So I moved all into the main project, a service. I then installed the FTP service on the working pc and did a try. Unfortunately running this sample (the machine is the same of the previous test) there the message if fired just after the file is created. I don't know why the behaviour occur. Certainly LastAccess doesn't mean last byte written, and file system architecture is quite different from what you think I'm thinking, I know. My question is just to know how this strange thing happen. A part of all. I thinked to solve the problem (know when file has been completely write) using a timer. When the file system event fires I add an entry into an hashtable or bi-dimensional array, in which I take trace of file's name and date-time, then fires the timer every 10 seconds. If, for example, for 3 times the last-access time stored in the array hasn't been changed, I can consider the file written (well or not, this certainly could be another problem, but because I'll zip file, if it won't be completely written, it'll certainly unreadable). What do you think of that? Thanks Andrea Tag: N Tier Architecture ? Tag: 101061

 - *.sln: starts with 2005 instead of 2003.. Hi, I had Visual Studio 2003 installed, and installed also visual Studio 2005 Beta 2. The problem is, when I am starting now (double click) a solution (*.sln-file), it always start it with Visual Studio 2005, and not 2003. I'm trying to change it in the registry, or jsut simply with an "open with" and the "always use this program to open"-option checked, but it doesn't work. Simply changing it in the "file types" in the explorer doesn't work either, it doesn't change there. Has anybody else had this problem? Anybody found a workaround? Somebody who has the 2 installed too? any help would be really appreciated! Thanks a lot in advance, Pieter Tag: N Tier Architecture ? Tag: 101054

 - strange error from win forms application (Failed to load resources Hi everybody, I've got a strange problem with my application (a windows application): I've got an application that is running on a client's production. (the system is dotnet v1.1 on windows XP sp2) Today the application suddenly displayed a message box with this error: Setup Error Failed to load resources from resource file. Please check your setup. While the message box was displayed the application was frozen (as far as I can tell all the threads in the application stopped working). When I clicked the OK button my Application restarted itself which is what it is supposed to do if an unhandled exception happens. (And now it's working OK). What does this error mean? My application does NOT use any resources (except,of course, for any resources generated by the visual studio for the forms). The strange thing is that, as far as I can see, the message box is shown BEFORE the exception reaches the unhandled exception handler. Now, the real problem is that while this message box is shown the application is NOT running. Nadav Tag: N Tier Architecture ? Tag: 101044

 - object-relational-mapping, DAL generator Hi, I'm ne to this subject, and has been looking around for some software that does the Object-Relational-Mapping, and generates the Data Access Layer. I found alreaddy a lot of application that doesn ice stuff, but none of them was really exactly what I was looking for. It need to be: - free (!!) - generates the code in VB.NET - doesn't use dll's, but generates just the code (!!) - preferably doesn't use stored procedures, but puts the code in the DAL - preferably open source The best I found until now was LLBLGen, but it makes stored procedures :-( I'm planning to use it with VB.NET 2003 and 2005, and SQL SERVER.

 - Cybersitter incompatible with .Net Framework? Actual trouble ticket follows. Reference DEJ-83192 to support@cybersitter.com I'm not a programmer, I've rudely crossposted this, and I apologize for all of that. I'm quite sure anyone here can point out many inconsistencies etc. I'm asking for folks here to download cybersitter and determine what the cybersitter program is doing that may kill .Net Framework communications within a network. I'm asking for straightforward feedback to my e-mail or the one above. I'm not a programmer, or developer, I'm a simple person pointing out that which will not work. With a truly laughable amount of time to fix that which will not work. I truly would like to see things work. SSEJohn. (I can get people where they need to be in a world that is working. I just need a world that works right to get them there.) posted: microsoft.public.dotnet.academic,microsoft.public.dotnet.distributed_apps,microsoft.public.dotnet.framework _________________________________________________________________ Don't close the ticket, this just took a turn for the ugly. Full description of problem follows. All Windows 98 SE Machines - No official server (Just one server program) Loaded Cybersitter onto healthy school network (no issues). 2 weeks later, received reports of ATP.com critical software won't start. Tried to run ATP software, seemed to try and start (processor clicking) Sudden stop of clicks, client side program fails to load. No error pop-ups or conflict popups. Attempted to run on several other identical machines. One loads the program, while running the cybersitter software. Next day, the working computer fails to load the ATP program. Turned off all filtering, then disabled cybersitter. Client side program failed to load. No error notices. Excluded filtering on all available ports. All filtering disabled. (all removed filters from client side and server side.) Client side program failed to load. Uninstalled Cybersitter from server and client. Client loads and runs ATP program. Contacted ATP. Their client/server arrangement is using Microsoft's .Net Framework ver 1.1 As I saw the client program run on one machine with Cybersitter running, I suspect a conflict with one of the automatic updates to Cybersitter. Nothing else in the network is auto-updating. I believe resolution to problem may lie in uninstalling the program and re-installing the program w/out updates. BUT, re-installation of Cybersitter appears to keep previously updated settings. I need a complete removal of all settings and previous updates that may be held onto. This may cause licensing problems (25 licenses for the lab). Currently running up a standalone installation of ATP to determine incompatibility of basic programming and to isolate .Net Framework incompatibility (which I suspect). Request instructions on removal of updates to prior installations of Cybersitter and licensing protections for the 25 computers in the lab which may require removal and re-installation for all computers. Further troubleshooting may resolve issues with .Net Framework compatibility (suspected) on a regulated Cybersitter updates installation. 5 year school re-certification by the ACCSCT for the school is tomorrow. The ATP software is critical to recertification to the school - the reason for all the sudden changes of priorities. All Cybersitter installations will be removed during the recertification process to enable access to the ATP program using the .Net Framework platform. This is, in fact, a fatal error for all should it remain unresolved. Or a bonus for all should it be resolved. Tag: N Tier Architecture ? Tag: 101035

1. I am in process of designing N-Tier Application using ASP.NET. Can
anyone guide me the right material or microsoft guidelines document
which I can used in designing the N-Tier application.

2. I would also like to know whether to use Web Services or .Net
Remoting in designing N-Tier application
3. General 3 Tier architecture has 3 Tier : Presentation Layer ,
Business Layer and Database Layer
How this 3 layers are seperated out in N-Tier architecture.

Help would be very much appreciated.

Thanks

It is separated by creating new project (usually a class project, web
service). Class project that will reference the web service that contains
business rules, computations or data.
