    - Problem with Sockets Hi, I'm developing a program who needs that user communicate via TCP over the net. One will be the listener and the other one the client, as usual. I've implemented the code as two classes deriving from a common interface. Everything seems to work OK until I use the Close() method. I've tried both using EndReceive(result) or commenting it. If I use it, the connection is not closed. If not, both applications close themselves: the one on the end-point with a error (not an exception, but an Windows fatal error). The code is below. Thanks in advance. If someone could help me, I'd be very pleased. using System; using System.Net; using System.Net.Sockets; using System.Text; namespace ThreatOfChaos.Connection { // This two classes are used in callbacks class MessageEventArgs : System.EventArgs { string message;

    - Looking for a better licensing technology We have a .NET class library with a built-in license-control system that checks for the presence of a digitally signed license file AT RUNTIME. This is a fairly standard technique that distinguishes between "trial" licenses (which only allows only limited functionality) and "full" licenses. We have not, however, figured out an effective way to apply licensing techniques AT DESIGN TIME. I have evaluated a few different licensing technologies and products and I have not figured out a way to achieve any control, record or react to what kind of license is present when code that is referencing our class licrary is bein compiled. I have explored the facilities for licensing in System.ComponentModel and (as far as I can tell) that only impacts what happens when a "component" is being visually manipulated by designer tools such as a Visual Studio forms designer. It does not seem to prevent anyone from compiling code that simply instantiates my classes and calls my methods, not does it record any licensing information when such code is being compiled. At a high level, what I want to achieve is that developers can use a trial license of my class library to compile and execute their own test programs, but they should not be able to "go live" until developers have obtained a "full" license, recompiled the app, and deployed to a machine that has a "full" license.

    - regex syntax I am new to using both dotnet and regex. I have done the basic reading to the point I thought I know how to use regex to extract date string. But I ran into problems. what is the best regex expression to look for month names or date string for that matter? from my testing, I could use "((JAN)|(FEB)|(MAR)|(APR)|(MAY)|(JUN)|(JUL)|(AUG)|(SEP)|(OCT)|(NOV)|(DEC))" not '([ADFJMNOS][ACEOPU][BCGLNPRTVY])" In other word I got syntax problem with the month pattern I am working towards dealing with various date format I deal with My object is to get the entire date string and parse into yyyy-mm-dd or whatever the dotnet conversion routine will take. I will have to deal with many long strings of 64K to 200K . This is the reason I am locking for a good regex expression to minimize delays from processing I know I have to deal with yyyy-mm-dd ( and variants thereof with dot or slash as separator instead of dash, single digit month or day) yyyy-MMM-dd ( or just space instead of -) MMM d, yy ( or yyyy) and the tougher ones like d MMM yyyy d MMM yy Tag: System.Web.Mail Tag: 101371

    - finally is not always being executed... Hi, I was under the impression that the finally block always got executed no matter what. Well I ran into a situtation that I can duplicate from a console app as well as a web application. For the console app if the try block is executing/processing its clode and the console app is closed the finally block is not called. The same is true for the web app. If the page_load or button_click is processing cose and it is wrapped by a try/catch/finally or try/finally the finally is not called if the web page is closed. Give it a try, I was blown away by this. I thought no mwatter what the finally block was called and I have very important logic that needs to be called. Below is very sloppy code, but it will do the trick to show this isn't working. The same goes for the console. Just put the try/finally in the main. Code: using System; using System.Data; using System.Configuration; using System.Web; using System.Web.Security; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Web.UI.HtmlControls; using System.IO; public partial class GeneralTest : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { Response.Write(DateTime.Now.ToString()); } protected void Button1_Click(object sender, EventArgs e) { try { System.Text.StringBuilder sb = new System.Text.StringBuilder(); for (int x = 0; x < 100000000; x++) { for (int y = 0; y < 100000000; y++) { sb.Append(x.ToString() + " " + y.ToString()); } } } finally { FileStream fsUpdateBackupDateTime = new FileStream(@"c:\zzzzcjm.txt", FileMode.OpenOrCreate); StreamWriter sw = new StreamWriter(fsUpdateBackupDateTime); sw.Write(DateTime.Now.ToString()); sw.Flush(); sw.Close(); } } } I guess is there anything that can be done or a way to make the finally or a block of code to be called if the console app or web application is closed?

    - Large images in comparison with VB6 Hi all, Our software need to work with large bitmaps (approx. 3 to 6 megabytes). Our previous versions were all build with VB6 and used the PictureBox control to load, zoom and pan the bitmap. It all works without a problem, and it is pretty fast. We are rebuilding our software in .Net and experiencing performance problems when it comes to loading, displaying, panning and zooming this large bitmaps. In other words: it is unacceptable slow. How come that the same techniques works flawless in a prehistoric [ :-) ] programminglanguage/environment and seem to fail completly in a modern one like .Net? I've already tried different approaches (like drawing directly on a graphics surface etc.), but zooming and panning of a large images is realy slow. Another thing is that those images consume lots more memory in .Net than it did in VB6.... Am i missing something here? Should i use DirectX? I've googled my *ss of, but i can't find 'the' solution..... Hints, tips, URL..... anything is helpfull... Greets, Erik. Tag: System.Web.Mail Tag: 101351

    - Misbehaving COM object? We have a .NET project that makes pretty regular use of a COM object that appears to be misbehaving. Am I correct in understanding that setting a COM object to nothing should act the same way that it would have in VB6? By this I mean it is actually destroyed and not marked for GC. We have an object that is called in a polling routine and looks to be leaking 6-8K at a time and never being reclaimed even though it is set to nothing. Is this possible in .NET or do we just have a poorly written COM object? TIA Tag: System.Web.Mail Tag: 101327

    - Namespace organization Any advice on how to organize my core class library project into sub-namespaces? What are the general rules of thumb regarding cross-namespace references? Can I have a class in namespace A have a function or a property that returns a class from a different namespace? For example, lets say I have a root namespace called ACME for my class library project. Under the root namespace are classes such as Individual, Address, etc. I also have a namespace defined for financial classes, called ACME.Financial, which contains classes such as Invoice and Transaction. Under Financial is a subnamespace called Discounts (ACME.Financial.Discounts). A second namespace under the root, called ACME.Groups, contains classes such as Group, GroupPlan, etc. ACME ACME.Financial ACME.Financial.Discounts ACME.Groups Now, if I'm coding something for the GroupPlan class in ACME.Groups, is it ok (I know it's possible but is it acceptable) to return an object of type ACME.Financial.Invoice from the ACME.Groups.GroupPlan class or should I stick to classes contained within the local namespace boundary (ACME.Groups) or higher (ACME)? Any thoughts or articles discussing Namespace coding best practices (all I could find were ones about naming standards - not enough detail regarding class layout) would be appreciated. - Dave Tag: System.Web.Mail Tag: 101324

    - WebRequest https and proxy authentication Hi I am using WebRequest object to access a https URL through a proxy: string Url = "https://www.verisign.com"; WebProxy proxy = new WebProxy("http://proxyserver.domain.com:80",true); proxy.Credentials=System.Net.CredentialCache.DefaultCredentials; WebRequest req =WebRequest.Create(Url); req.Method="GET"; req.Proxy= proxy; result = req.GetResponse(); The proxy server requires NTLM authentication. This code works fine if (a) The URL is an http site (b) the URL is a local https site (therefore bypassing the proxy) but doesnt work where proxy authentication is required for an external https URL. I can access the https site fine through the proxy in IE so the proxy and authentication are clearly working OK. I have read another post that indicated this was an issue in .NET Compact Framework (http://www.dotnet247.com/247reference/msgs/51/255270.aspx) - does anybody know if this is also the case with .NET on W2003? Or is there something that I am missing? Any help gratefully received. Tag: System.Web.Mail Tag: 101323

    - Socket data out of order I am using asynchronous socket receives and writing the data to a disk file. I am finding all of the data makes it to the file, but it is SLIGHTLY out of order. The approach is to create a pool of contexts, each which has a 1K byte buffer. Then I start it all by getting a buffer from the pool, and do a BeginReceive on the socket. In the receive completion handler I call EndReceive. THEN get a buffer from the free pool, and I invoke BeginReceive again. If my buffer pool was exhausted I would allocate a new one, rather than stall. THEN I invoke BeginWrite to write the just-received data to the disk file. In the write completion handler I return the context and buffer to my buffer pool. I am managing my buffer pool in a .NET "Queue". I protect all Enqueue and Dequeue with Synclock on the Queue object. Enqueues and Dequeues seem to have integrity, in that there are the correct number of buffer pools in the queue when the whole thing winds down. Without the disk writing I get about 60 MBits / second maximum received on the socket. When I involve the disk writing it hunkers down to about 22 MBits / second. My pool size is initially 25 contexts/buffers, but typically grows to about 80-90 with very large and very fast transmissions. I don't queue up multiple simultaneous socket receives. I know that doing that could easily result in EndReceives firing out of order with the data stream. But obviously I am queueing up to about 80-90 pending disk writes. But they SHOULD be queued up in the order they were received. And I understand they should then end up in the disk file in the correct order. I suspect something about this aspect of writing to the disk is what is getting the data out of order. Can you see what I am doing wrong? Or perhaps there are some known bugs in the Framework? Maybe I need a SyncLock that entirely covers the segment of code starting with the EndReceive and ending with the BeginWrite? Tag: System.Web.Mail Tag: 101318

    - Multicast Sockets: no sending with active local Internet Connection I have a Multicast Sockets Chat / Picture Program that runs correctly when there is no Internet Connection on the local Machine. 2 Chat Programs run correctly on the same Maschine (when different Ports are used). 1 Chat Programm on each Maschine also works correctly. 3 Chat Programs run correctly on the both Maschines (when different Ports are used on the second Machine). But when the local Internet is started on the first Machine the Chat program on that Machine cannot recieve or send. The second Chat on the second Machine recieve however the Message from the first Chat on that Machine. What could be the cause of this be? The ports for the Fireball are OK (when newly compiled, it allways asks). The Group used is : 234.77.77.0 - could it be something with the '234' ? I have recieved Mails with similar reports. On another LAN (also without Internet) everything is OK. I have been told that on a LAN where the Internet Connection is on some other Machine it also works.

    - ADO.NET and SQL Server Data Paging I had to built a custom data paging control for my asp.net app and SQL Server. This is what I'm doing: 1. do a SELECT to a SqlDataReader 2. create a DataTable with data from GetSchema() 3. loop trough the datareader using .Read() to the point I want to start 4. add data to DataTable with max of [pageSize] records 5. close the data reader and return The question is: Isn't looping reader.Read() doing nothing to go to start point where I want start getting data too expensive? Although DataReader is fast, won't ".Read()" get the row data from the server to the client? If so, if I need to get data from record 10000 ahead, it is actually reading all 10 thousand rows of data, so it is a big waste of resources. Maybe someone who knows more about the internals of the DataReader can answer this. Since SQL Server doesn't support "LIMIT" like keywords, if there is a better way to page data in sql server, I would like to know. Thanks. Tag: System.Web.Mail Tag: 101297

    - Implementing / using the IExpando interface Guys, Does anyone know much about the IExpando interface? I have a business object I've created and I'd like to add support for methods / attributes at runtime so that scripting clients ( e.g. ASP / VBScript / Java script ) can call the .NET object through a RCW and invoke methods which are added at runtime. Do I need to inherit my .NET class from IExpando and implement methods such as AddMethod. Are these called by the scripting engine to resolve methods which don't exist. e.g. assume a query class contains methods such as Save however a method Resolve needs to be added at runtime so I can write code such as oQuery.Resolve.

    - SQL + Dreamweaver Hello, I seem to be running into a problem with regards to data size etc: Explanation: A person opens a .aspx page and posts and writes an article of a few thousand words. When they click Insert Record they get this message: System.Data.SqlClient.SqlException: String or binary data would be truncated. The statement has been terminated. at System.Data.SqlClient.SqlCommand.ExecuteReader(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream) at System.Data.SqlClient.SqlCommand.ExecuteNonQuery() at DreamweaverCtrls.DataSet.DoInit() Problem: It's to do with the size of the data being inserted into the record and I have increased the VarChar length to 6000 characters to compensate. Is there a better DataType to hold the information? With MS Access this is a major problem but I would expect that but not with SQL Server? Any suggestions? Tag: System.Web.Mail Tag: 101288

    - Determining the path to the .NET framework Is there a canonical way to determine the path to the folder where the runtime environment is installed? The reason I am asking is that I have created a small Office Add-In in C# which needs to be registered as a COM component using regasm.exe during installation. So I need a way for the install script (the Add-In is only a part of a larger project which does not use the default Microsoft installer) to find the regasm, since it is not in the path by default.

    - Drag and Drop Question I've been looking around for info on this, but not finding much. What I'm trying to do is allow a user to drag and drop objects between two forms in my app. The objects are classes that I've built and I want the target form to be able to recognize what kind of type is being dragged over it and dropped. From what I could tell from the MSDN docs, I apparently need to add a custom dataformat type to the existing list, and/or to register a new data type in the registry. Can anyone explain exactly how I need to do this, or point me to a tutorial somewhere? I'm pretty stuck on this one. Thanks! Tag: System.Web.Mail Tag: 101280

To me, this directly states that when I Pulse a locked object that has threads waiting, a thread that is waiting with a timeout will be moved to the ready queue ahead of a thread that is waiting without a timeout. It also rather strongly implies that a thread that is about to timeout will get priority ahead of a thread that is willing to wait longer. Yet, the attached program wakes waiting threads in creation order, exactly as if a Pulse or PulseAll simply moved threads from the waiting queue to the ready queue in the order that they entered the waiting queue.

    - Is serialport functional in beta2 on .NET CF? We're trying to do serial comm with the new serialport object in the VS Beta 2/.NET Beta 2 system (using C#, but I don't think that's terribly important). I'm using a slightly cranky GPS receiver, and it works fairly well under Windows, but when hangs hard in the PocketPC 2003 emulator, and on an actual iPaq handheld. Does anyone have a SIMPLE code snippet that works for serial comm for them under the Compact Framework? serPort.ReadLn() or similar would be sufficient. I'd like to see if it's our device, or the serialport object, or improper use of serialport, etc. Many thanks in advance! --Larry Tag: System.Web.Mail Tag: 101251

    - A Question about Control.Invoke I have a code sequence that goes something like this: 1. Start an asynchronous i/o with a completion callback of /cb/ Now when the i/o completes we end up in the /cb/ routine.... note that we are in a pool thread during the callback, not the main form's thread. 2. call the Endxxxx(ar) to retrieve the results of the operation 3. form.Invoke(delegate method, params) 4. do another asynchronous i/o for more data At step 3 we call Invoke to switch to the main form's thread and pass it some data. This is necessary since doing anything with form's controls outside its main thread is not safe. My question is what is Invoke doing under the covers? Does it just launch the delegate with the equivalent of a PostMessage or PostThreadMessage and return straightaway so we can get the next i/o started at step (4), or is step (4) not executed until the delegate method (and any routines it calls in turn) in step (3) completed? I can change Invoke to BeginInvoke if that is what is required. Regards, Oz -- A: Because it fouls the order in which people normally read text. Q: Why is top-posting such a bad thing?

    - Implementing a namespace over more than one assembly? 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: System.Web.Mail Tag: 101240

    - Delphi 4 & VB.NET, don't play nice?? Hello all, Im stumpped. I have a small app i wrote in VB.NET which takes in a file name, and a bunch of other params, runs the file with the params, and then exits. At the end of the program, it can optionally echo back all the params it received in a msgbox. When the app is run from a command-line, it works beautifully. The report runs, then when you close it, the msgbox pops up with the params that were passed into my launcher program. HOWever.... we have another application, written in Delphi 4, which attempts to run the same command line as we tried running manually. When it is run from the Delphi app, the msgbox with the params never pops up. The Delphi app is shelling out to my app using the delphi command WinExec(). Is there some weird interaction between Delphi 4 and VB.NET or the .NET framework in general, that would prevent this msgbox from showing up???

    - Too many pending asynchronous disk write causes spurious errors I am using the asynchronous I/O model to receive data over a socket, and asynchronously write the incoming data to a disk file using FileStream. So long as the pending writes have not yet completed I continue to allocate more read buffers. As a result I can get a backlog of about 250 disk writes (1K buffers, because that is the max size the receiver will give me). During the course of a 50 MB transfer I get about 6 of these errors: 07:42:50.14 System.IndexOutOfRangeException: Probable I/O race condition detected while copying memory. The I/O package is not thread safe by default. In multithreaded applications, a stream must be accessed in a thread-safe way, such as a thread-safe wrapper returned by TextReader's or TextWriter's Synchronized methods. This also applies to classes like StreamWriter and StreamReader. 07:42:50.14 at System.Buffer.InternalBlockCopy(Array src, Int32 srcOffset, Array dst, Int32 dstOffset, Int32 count) 07:42:50.14 at System.IO.FileStream.BeginWrite(Byte[] array, Int32 offset, Int32 numBytes, AsyncCallback userCallback, Object stateObject) 07:42:50.14 at ODP.NMServe.DataChannelSession.ReceiveHandler(IAsyncResult ar) I am obviously doing SOMETHING wrong. I was thinking the FileSystem.BeginWrite was supposed to be safe to work from in the thread pool utilized by the socket read completions. And that there was safe FIFO queueing of requests. The FileStream was opened with the asynchronous option TRUE. I am not sure what the error messages are looking for, what I need to change to avoid this. The disk I am writing to is an SCSI RAID 5 disk array. This runs on a dual processor W2K box. Thanks for any pointers Best regards - Lee Gillie Tag: System.Web.Mail Tag: 101224

    - Disk file write performance Seeking some hints from a real framework asynchronous I/O ru of gu. I am trying to find the absolute fastest way to write binary data to disk files in VB.NET. I am working on an FTP server. In my development testing I have found that I can receive about 60 mbits/sec over the socket data connection using asynchronous reads, with the file writing disabled. When I try to incorporate asynchronous disk writing with FileStream it bogs down to about 4.5 mbits/sec. So I start with only three, but I allocate extra data buffers as needed to keep feeding the socket reads as fast as the system will take them, and obviously not reuse the buffers until the asynchronous disk write completes, and I find my buffer pool grows to about 250 (i.e. up to 250 pending asynchronous disk writes at any one moment). I/O buffers are 1K each. File transfers are about 50 MB. Thanks for any pointers Best regards - Lee Gillie Tag: System.Web.Mail Tag: 101222

    - Exception on Machine Without Visual Studio .Net Installed I have created a mixed mode (managed + native) application that links to a mixed mode dll. It runs fine on all XP machines with Visual Studio .Net installed, but on other machines with the .Net framework installed but not Visual Studio, it displays a pop-up window entitled "Common Runtime Debugging Services," and the unhelpful message: "Application has generated an exception that could not be handled." This happens when the application gets to the managed-code wrapper of a function (C++) that initializes the dll (__crt_dll_initialize) . The error is triggered just before it enters the crt-initializing wrapper function. It won't display a message-box window placed within the function but before the initialization. Try-catch does not catch the error. Depends.exe show no missing or problematic module. The error also is triggered when 0 is assigned to a pointer to a managed class of the dll. Any suggestion would be appreciated. -- sunrat Tag: System.Web.Mail Tag: 101220

    - Uninstall 2005 Beta 2 and reinstall 2003 Hi all, I've uninstalled Visual Studio .Net 2005 Beta 2 and need to reinstall Visual Studio .Net 2003 but I get an error that the .Net Framework 1.1 and J# redistributable packages cannot be installed. Is there a tool to clean up the mess the Beta leaves behind? Thanks, Ivan Tag: System.Web.Mail Tag: 101219

    - Custom Class - Different Instances Hello, I have a custom component class that I created that will basically save x amount of "objects." Once x + 1 object pops in, the oldest one falls off. It works great as I have it. In my test web page I create a Static object and use the New to create a new instance of it. If I don't use the Static, nothing is remembered. The only problem is, when I start a second page, I expect it to have a NEW instance of the class but the numbers stored show up the same. How do I get it to always create a New instance. Am I missing the public, private, protected, internal - modifiers in the wrong position? Please help. - - - - - - - Class File: using System; using System.ComponentModel; using System.Collections; using System.Diagnostics; namespace NASQLStatements { public class ThingsRemembered : System.ComponentModel.Component { private System.ComponentModel.Container components = null; private int iThingsToRemember; protected internal ArrayList aThings; public ThingsRemembered(System.ComponentModel.IContainer container) { container.Add(this); InitializeComponent(); aThings = new ArrayList(2); } public ThingsRemembered() { InitializeComponent(); aThings = new ArrayList(2); } public ThingsRemembered(int iCapacity) { InitializeComponent(); aThings = new ArrayList(iCapacity); } public ThingsRemembered(System.ComponentModel.IContainer container, int iCapacity) { container.Add(this); InitializeComponent(); aThings = new ArrayList(iCapacity); } protected override void Dispose( bool disposing ) { if( disposing ) { if(components != null) { components.Dispose(); } } base.Dispose( disposing ); iThingsToRemember = 0; aThings.Clear(); // delete all items aThings.TrimToSize(); // resize the array to system default } #region Component Designer generated code private void InitializeComponent() { components = new System.ComponentModel.Container(); } #endregion public int ThingsToRemember { get { return iThingsToRemember; } set { iThingsToRemember = value; aThings.Capacity = iThingsToRemember; // size the array } // set } // ThingsToRemember - Property - Read/Write public bool AddAThing(object oThing) { try { if(aThings.Count == aThings.Capacity) { aThings.RemoveAt(0); // remove the oldest one } // if there are already the maximum number of items in the array aThings.Add(oThing); // add the new one return true; } catch(Exception e) { sLastError = e.ToString(); return false; } // try-catch errors } // AddAThing - Method public string LastError { get { return sLastError; } } // LastError - Property - Read Only public object LastThing() { return aThings[aThings.Count - 1]; } // LastThing - Method public object FirstThing() { return aThings[0]; } // FirstThing - Method public ArrayList AllThings { get { return aThings; } } // AllThings - Property - Read Only } } - - - - - - - Test File: using System; using System.Collections; using System.ComponentModel; using System.Data; using System.Drawing; using System.Web; using System.Web.SessionState; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.UI.HtmlControls; using NASQLStatements; namespace TestThings { public class WebForm1 : System.Web.UI.Page { protected System.Web.UI.WebControls.Button cmndAddThing; protected System.Web.UI.WebControls.Button cmndShowThings; protected System.Web.UI.WebControls.Label lablThings; private static NASQLStatements.ThingsRemembered oStuff = new NASQLStatements.ThingsRemembered(); private void Page_Load(object sender, System.EventArgs e) { if(!Page.IsPostBack) { oStuff.ThingsToRemember = 5; lablThings.Text = oStuff.AllThings.Capacity.ToString() + "<br>" + oStuff.AllThings.Count.ToString(); } // if this is the first time to the page } #region Web Form Designer generated code override protected void OnInit(EventArgs e) { InitializeComponent(); base.OnInit(e); } private void InitializeComponent() { this.cmndAddThing.Click += new System.EventHandler(this.cmndAddThing_Click); this.cmndShowThings.Click += new System.EventHandler(this.cmndShowThings_Click); this.cmndError.Click += new System.EventHandler(this.cmndError_Click); this.Load += new System.EventHandler(this.Page_Load); } #endregion private void cmndShowThings_Click(object sender, System.EventArgs e) { lablThings.Text = "" + oStuff.AllThings.Capacity.ToString() + "<br>"; for(int iPos = oStuff.AllThings.Count - 1; iPos >= 0; iPos--) { lablThings.Text += oStuff.AllThings[iPos].ToString() + "<hr>"; } // for each item } private void cmndAddThing_Click(object sender, System.EventArgs e) { Random rRandom = new Random(DateTime.Now.Millisecond); int iValue = rRandom.Next(1, 1000); lablThings.Text += "<br>" + oStuff.AddAThing(iValue).ToString(); } } } As you can see, in the Test file I declare the Class as private static and do a NEW. I assumed the New is necessary so it can create a New instance of it. If it take out the Static modifier, nothing works and no random numbers are stored. If I leave it in, it will remember the number (5) I have told it. But so will each new web page I bring up and point to that page. Please help. -- Thanx, Kevin Tag: System.Web.Mail Tag: 101212

Hello, friends,

I installed .net Enterprise Architect version 2003 (Fraimework 1.1, version
1.1.4322) in my machine, and tried to run sample C# source code that has
statement: using System.Web.Mail

However, when I compiled it, I got erros, saying "Mail" does not exist in
the class or namespace "System.Web". I checked the MSDN Library coming
together with .net, it says "Systme.Web" does contain namespace "Mail"

To eliminate the possibility that I did not install in my first
installation, I then installed all missing components, but the error is still
there. What is wrong here? Help please....

Thanks a lot.

Have you included a reference to the System.Web.dll file?
