    - namespaces hierarchy hi, how are namespaces distributed in assemblies? is there only one dll which comtains all the namespaces with "system" namespace as root of all the namespaces or there are different assemblies that has namespaces that come under system namespaces. if there are more than one assemblies for the .net framework api ,then how is it handled. say how can "data" namespace come under "system" namespace being in different assembly. how the hierarchy is maintained. regards amit Tag: 1.1 Framework and IIS Tag: 56958

    - Server Application Unavailable - Please Help! Geetings all, I'm getting the following message in Internet Explorer when trying to run an ASP.NET app or QuickStart sample: ------ Server Application Unavailable The web application you are attempting to access on this web server is currently unavailable. ... etc. ... etc. ... ------ This happens after a brand new installation of Visual Studio .NET (2002) Enterprise Architect on my "test server". The installation sequence I followed was: 1. Reformat the Hard Disk 2. Install Windows XP Professional 3. Install IIS 5.1 (from WinXP CD) 4. Install WinXP SP1 5. Install utilities (virus protection, WinZip, etc.) 6. Set up Internet and LAN connections 7. Install all Security Updates for WinXP from windowsupdate.microsoft.com site 8. Install SQL Server 2000 Enterprise Edition 9. Install SQL Server 2000 SP3a 10. Install Visual Studio .NET (2002) Enterprise Architect 11. Install .NET Framework 1.0 SP2 12. Install MSDE 2000 manually from SQL Server 2000 SP3a, using the NetSDK named instance 13. Manually installed the .NET Framework SDK QuickStart samples according to the "SDK Samples Configuration Details" document From what I can see everything installed OK - so it must be a setting somewhere that I'm missing ... or something. Any help will be appreciated. Adam P. Tag: 1.1 Framework and IIS Tag: 56957

    - Designers for System.ComponentModel.Component do not always Add to parent Container Some designable Components (objects of type System.ComponentModel.Component) when dropped onto a Component class create code to add themselves to the parent component Container and some do not. This behaviour seems inconsistent. Components that do *not* Add themselves to the parent class Container are not Disposed of automatically when parent.Dispose() is called, and must be Disposed in some other way. If all components Added themselves to the parent Container, then all could be Disposed by calling parent.Dispose() Example: - Create a Class Library project and add a Component Class (Component1.cs) to it. - From the toolbar, drag and drop a Windows Forms.Timer object - From the toolbar, drag and drop a Data SqlCommand Note the following code created: private void InitializeComponent() { this.components = new System.ComponentModel.Container(); this.timer1 = new System.Windows.Forms.Timer(this.components); this.sqlConnection1 = new System.Data.SqlClient.SqlConnection(); } Note that timer1 is added to the "components" Container, but SqlConnection1 is not added. When the parent component is Disposed, timer1 *will* be also Disposed, but SqlConnection1 will *not* be automatically disposed. If the Visual Studio designer also added the following code: this.sqlConnection1 = new System.Data.SqlClient.SqlConnection(); this.components.Add(this.sqlConnection1); ... then, with this extra code, when the parent is Disposed, the SqlConnection will also be disposed, which would be very desirable automatic behaviour. (Or use an overriden New() method that takes a Container argument) Other newsgroup articles that seem to raise this question/problem are: http://groups.google.com/groups?threadm=u97MlC3%24CHA.2172%40TK2MSFTNGP12.phx.gbl http://groups.google.com/groups?threadm=u%23JwGeHnCHA.1828%40TK2MSFTNGP08 Please change Visual Studio .NET to behave in the manner suggested above. (Or please explain why it should be the way it currently is... :-) Thanks, Mark Cranness Tag: 1.1 Framework and IIS Tag: 56956

    - onverting .tlb library produces incomplete types Hi all, I am trying to use a COM library from my .NET application. I built .tlb from .idl file and run TlbImp.exe on .tlb to produce an interoperability assembly. During conversion, a number of warnings are issued: .... TlbImp warning: Type IMyType is invalid and may only be partially converted. .... In resulting assembly all types referenced in these warnings are incomplete, some members are missed. What is the possible reason and how to work around the problem? MIDL compiler says nothing about these types, so I can guess that the problem is specific to TlbImp.exe Thanks in advance, Dmitry Tag: 1.1 Framework and IIS Tag: 56949

    - Is socketbuffer empty? Hello Fellow Developer, This looks like a long mail, but at the end of this post is my socket wrapper attached. I want to make a timeout procedure that starts counting down after the socketbuffer is empty. This connection is being used to transmit data following a RFC so I cann't create a control protocol that tells me the data was received. (And even if I could, I want the timeout procedure to start after I send all data, because that makes for me the most sense. (say I am sending 128mb the socket will take longer sending then the timeout interval)) Any questions/remarks, NOT related to my question, pls ask directly via email, dont post on the news server because It toke me alot of effort to create this post. Sample case: if u send 1 byte from a client in Canada to a server in Australia with a 28k modem thats being shared by an office of 30 people connected to the slowest profider. (etc.) What I want to say is that 1 byte may take a couple of minutes, and I use 1 byte as an example because I don't want to make a question more complicated. TCP/IP is a async protocol, but due to the Berkley Connection engine it keeps track of what was send and received and what was not, so when there is a packet loss it will send again. So a socket keeps the data sequential, and if we are optimistic, the only thing that can go wrong is a socket error. There are three stadiums(simplified): (A) My object sends to the Winsock, (buffer is being fed, no data on the network, no data on the remote point) (B) Winsock processes his buffer and sends on the network and waits for a confirment that the package is succesfull transmitted(buffer is 'empty', data on the network, no data on the remote point) (C) All data is correctly processed and transported (buffer is truely empty, no data on the network,data on the remote point) Relative to the Sample case: I achieve (A) ofcourse, I would really want to know (C), but I would be satisfied with (B). I know (B) can be achieved, I hope (C) is too. VB.NET FrameWork 2003(all patched and updated): I use the System.Net.Sockets to send/receive data (no tcpclient/tcplistener), I made a receivethread in my wrapper, the receivethread loops/sleeps while waiting for data and then fires a datareceived event. Within the waitingloop there is a timeout function but this doesn't work properly (It will never timeout). When I send by System.Net.Sockets.Socket.Send(buffer()) (<--this can be 10Mb) then it imitially returns to my thread, so the (internal) Send method buffers it. The System.Net.Sockets.Socket is a wrapper around the Win32 Socket 2 API's, it makes internal calls to those api's, so I started reading if they forgot implementing some functions, but they are all implemented. I tried: - The beginSend/EndSend (Async way with callback when command is finished) This calls within the async object the Socket.Send method, so its no help, I can better do Socket.Send myself. - The Socket.Blocking Property, it only blocks the Receive method, Socket.Send goes directly in the buffer and then it returns immitially. - Socket.Poll Method, returns the accessrights of the socket, "may I use this socket to write?" - getSocketOption(Socket/TCP/IP,SendBuffer/ReceiveBuffer/SendLowWater/ReceiveL owWater/SendTimeout/ReceiveTimeout) Method Throws an Exception MyWrapper.vb: Imports System

    - Serialization & Events problem Hi, I have a class which I have marked with the serializable attribute. All the serialize code works untill I added an event to the class. An now, when I come to serialize the class, it wants to serialize the class where an event sink is defined I can only stop this by removing all the events from the class before serialization, and adding them back after. C# will not let me add [NonSerialized()] to the event variable defintion. Thanks Peter Tewkesbury Tag: 1.1 Framework and IIS Tag: 56945

    - Solution to maintain single instance I want to maintain single instane of my application. So I use the following code. bool bCreateNew; string strName = "Temp"; _Mutex = new System.Threading.Mutex(true, strName, out bCreateNew); if (bCreateNew == false) { IntPtr hPrePop = FindWindow(null,strWindowName); if (hPrePop != IntPtr.Zero) { //Pop up the previous instance ShowWindow(hPrePop); SetForegroundWindow(hPrePop); } } But my application is originally put in the tray, I want the application to return from tray if the user attempt to open a new instance. So how can I call the previous instance to set the the visiblity of the tray icon to be false? What I mean is puting what code inside the if - block (i.e. if (hPrePop != IntPtr.Zero)) can achieve my goal? -- Franz Wong My C++ and C# Site (Traditional Chinese) : http://www.franzwong.com Tag: 1.1 Framework and IIS Tag: 56944

    - passing structs from VB to C# and back to VB Hi All, I have the following situation: Assembly VB defines a structure in VB.NET: Public Structure TP Public i As Integer End Structure Assembly CS (in C#) uses this structure and returns it from a function CONV.exec() ). Additionally it defines a second test struct and a second function to return the test struct: public struct TST { public int i; } public class CONV { public static VB.TP exec() { VB.TP tp =new VB.TP(); tp.i=42; return tp; } public static TST exec2() { TST tp =new TST(); tp.i=42; return tp; } } The assembly has a reference to assembly VB Now the assembly VBCA (writen in VB) uses the C# assembly. It references the VB and the C# assembly: Sub Main() Dim tst1 As VB.TP = CS.CONV.exec()'doesn't work, struct defined in VB Dim tst2 As CS.TST = CS.CONV.exec2() 'works, struct defined in C# End Sub The compile of the first statement fails, when the Type is defined in a VB assembly: error BC30652: Reference required to assembly 'VB' containing the type 'VB.TP'. Add one to your project. However, the second statement that uses a C# defined struct that is absolutely identical to the VB one compiles and works. Any ideas what is the culprit?

    - Serious problem with ShowDialog and ShowInTaskBar=False My product is an Add-In for Visual Studio .NET. Because the Add-In should work with VS.NET 2002 and 2003, I am still compiling it with version 2002. I have encountered a problem with the Form.ShowDialog() method, which only occurs when running in VS.NET version 2003. However, I have no idea as to whether the problem is specific to this constellation, in fact I doubt it. Many of the forms in my project use COM controls. Following the advice in Microsoft Knowledge Base Article - 312120, http://support.microsoft.com/default.aspx?scid=kb;EN-US;q312120 I have added the statement "Me.ShowInTaskbar = False" to the Form_Load method of some forms. The problem that occurs it that the method Form.ShowDialog() returns immediately, without showing the form and returning the status Cancel! Clearly this is intolerable and would appear to be a serious bug in the .NET framework. I have now, luckily, discovered that there is a connection between this behaviour and the statement "Me.ShowInTaskbar = False" in the Form_Load method. After commenting this statement out, the form is displayed correctly (but with a fairly pointless button on the task bar). As you can imagine, this is particularly annoying, since I added this statement following instructions from Microsoft. By the way, there is a newsgroup thread entitled "ShowDialog() returns immediately with "Cancel"" describing a similar problem, indicating that it is important to use the overloaded call Form.ShowDialog(IWin32Window). In my case, this did not solve the problem. Phil Tag: 1.1 Framework and IIS Tag: 56908

    - The FREE .Net Framework means NOTHING IF SQL SERVER........... SQL Server is easy to use.... Yet, "Easy-to-Use" is NOT IMPORTANT if it's not "Easy to AFFORD"..... Moreover, those who need it to be easy to use (those who don't have a Fortune 500 IT staff)...need it to be easy to AFFORD. ***THE CATCH 22 *** What good is a Free .NET Framework and a low cost Windows 2003 Server-Web Edition, if SQL Server costs more than the server and ISP network connection and amount to at sometimes at least 50% of the total costs when developers have had to drop their hourly rate in half? ANSWER: change your SQL Server licensing policies to be more friendly to mom and pops instead having them run to PHP and MySql because they are not going to MS Access after they have had PHP running nice and fine and then do a port to sql server. Because they, MOM and POP and startup company are going to be HAPPY with MySql and PHP and are NOT going to pay GOBS of money to do an entire PORT when (by the time they really NEED a faster system) they could just buy a faster computer. PERIOD..... Dear Microsoft and the Marketing department, There can only be 500 companies in the Fortune 500.... That's why MySql and PHP are so hot right now...... Do not think that the developer and entreprenuer don't have to sit down and total up the costs? And then see what the cost are for SQL Server and see how they can double the total costs. Don't have the CEO look at the licensing cost on the Microsoft SQL Server page, their eyes will roll as the developer IS NOT going to be at the CEO's side 24 hours a day.

    - Console vs Service Application I'm writing an application that needs to run every x minutes, read in some data from a log file and then write it out to a database. Originally I was going to write it as a service but the more I think about it I feel it would work just as well as a console application that is scheduled using the Windows scheduler. I'm just curious as to whether there are any other advantages to using a service that I might not have thought of? Here are some reasons why I thought a console application would be acceptable: 1. It is easier to schedule the console application using the Windows scheduler or 3rd party scheduling applications, using a service I would need to write scheduling code into it 2. It doesn't matter if the application is manually run between scheduled periods 3. It could be handy to write output to the console so if someone manually runs it that can see what is happening Any thoughts would be greatly appreciated. William D.

Why? Is this a normal behaviour? Is it impossible to get rid of the empty columns when using the export funtion of the report? Please clarify me so that I can decide to either use the export functionality of the report or to implement my own excel export. I rather use the export functionality of the report itself if I can get rid of the empty columns. -- Thanks in advance Ali Eghtebas Sweden Tag: 1.1 Framework and IIS Tag: 56879

    - Question: How do you retrieve Properties provided by an ExtenderProvider through reflection? Hi, I've written a simple ExtenderProvider that provides a string property (Let's call it CustomStringProperty) to all the buttons on a form. The ExtenderProvider itself is placed on a base form (It is protected, so derived forms will inherit it's functionality) and provides the CustomStringProperty to all forms derived from it. It's canonical and works well. It allows the values to be assigned during design time. Thereby easing the development of new forms and insuring that all the buttons on new forms (that derive from the base form containing the ExtenderProvider) have the CustomStringProperty. Now I'm writing a small external tool that is attempting to extract these CustomStringProperty(s) through reflection and log their value in a database. However, It's my understanding that the values of the CustomStringProperties are assigned during the InitializeComponent() method call of the associated forms (which to my knowledge doesn't get executed during reflection). And I don't think that the properties extended by the ExtenderProvider show up in the fieldinfo of the buttons themselves, rather that you must go throught the ExtenderProvider during runtime. Am I wrong? Any advice would be welcome. Thanks Jason Tag: 1.1 Framework and IIS Tag: 56878

    - efficient C# coding I'm looking for a good article on efficient C# coding. All the DotNet efficient coding articles I can find are oriented toward VB.NET, and while some principals still apply, many do not. For instance there is no equivalent of with (some object) . end with in C# (or somebody straighten me out). Somehow in the my early studies of C# I got the (apparently wrong) impression that it had some kind of great compiler that made all the good practices I learned in VB unnecessary. Consider the following: private static void LoadHeadings(UltraWebGrid Grid, XmlNode[] PrevHeadingArray, SortedList FootnoteList, int CurRow) { for (int i = 0; i < PrevHeadingArray.Length; i++) { Grid.Rows[CurRow].Cells[i].Text = PrevHeadingArray[i].Attributes["text"].Value + SuperFootnotes(PrevHeadingArray[i].SelectNodes("child::note"), FootnoteList); Grid.Rows[CurRow].Cells[i].Style.VerticalAlign = VerticalAlign.Top; } } I need to access the same cell twice, and I do it down a fairly long path. Nowhere have I seen it advised to assign the object to a local variable and then access it, yet when I did that the following code generated considerably less code in the debugger disassembly: private static void LoadHeadings(UltraWebGrid Grid, XmlNode[] PrevHeadingArray, SortedList FootnoteList, int CurRow) { for (int i = 0; i < PrevHeadingArray.Length; i++) { UltraGridCell oCell = Grid.Rows[CurRow].Cells[i]; oCell.Text = PrevHeadingArray[i].Attributes["text"].Value + SuperFootnotes(PrevHeadingArray[i].SelectNodes("child::note"), FootnoteList); oCell.Style.VerticalAlign = VerticalAlign.Top; } } I can't really interpret the assembler code, but I figure less code is usually a good proxy for more efficient code. Judging from my VB experience the next step would be to assign "PrevHeadingArray.Length" to a local integer. Am I on the right track? I really don't have the time to pursue these interesting investigations, and I haven't taken the time to instrument the example above and see what the comparative elapsed times are, I would much rather read this all spelled-out somewhere.

    - Version Changes 1.0 to 1.1 I have a simple aspx page that used to run properly in framework 1.0. Now that I moved to 1.1 the validation controls do no run. I just installed Framework 1.0 and also changed the config file so accept 1.0: <configuration> <startup> <supportedRuntime version="v1.0.3705" /> </startup> </configuration> But still does not work. The page does run the control validations. Any ideas ? Thanks, Sergio Tag: 1.1 Framework and IIS Tag: 56869

    - Read from COM port? I need to read messages from a device connected to a COM port with the following format: When the controller is configured to report events, it will transmit a new message every time the event occurs. The message follows the following format: XX <Message> {CR} {LF} {Terminator} . "XX" is the Message ID Number. Each type of report message from the controller has a unique ID number in a 2-digit hexadecimal format. Each digit will be a hexadecimal value (numbers 0-9 or letters A-F). When converted to decimal format, they represent the numbers 0 through 255. By reading these two bytes, a user program can quickly identify the type of message from the controller. . "<Message>" will contain a text description of the event. . {CR} signifies that a carriage return is sent. . {LF} signifies that a line feed is sent. . {Terminator} signifies that a single-byte terminator code is sent. The byte has a value 1d, which is the ASCII code SOH (this is NOT the number 1, which is ASCII value 49d). The terminator is provided to make it easier for a computer program to read and interpret the messages from the controller. What framework clases are best suited for reading this kind of messages from the device? Can you specify the terminator character which is at the end of each message? -- Olav Tollefsen Tag: 1.1 Framework and IIS Tag: 56862

    - .armx? I've noticed on various msn.com webpages the .armx extension. Perusing various search engines has turned up nothing except for a single webboard thread which talked about msn.jp and someone's theory that it is a personal .NET extenstion system for MSN.com because you can easilly create your own extensions. Is this true? And if not? Just what is this? Some sort of new technology? I doubt they'd want to replace asp.net so soon, right?

    - ADO.net Hey, i am bit concerned about the architecture provided in the .net frame work for ado.net. The disconnected architecture does nor serves you best on the desktop application. As you are not connected to database and if any other changes the table in the database you are not notified or your side data is still older one. As it was not in ADO we use to set the recordset properties to our need and we were quite happy. but not now. Example: Dim rs as ADODB.Recordset TextBox1.databindings.add("Text",rs,"id") (X) which is not allowed by the .net frame work, as i am using the Recordset that is in ADO not in ADO.Net and its required interface is not present. But i want to do that ... as it is quite easy to use this structure. I think there is problem with Microsoft they dont even support there ADO properties in their .net TextBox or any other control. They should provide the Implementation of connected recordset or simply implement the IList interface or any other interface that is required for the data binding in .net fram work. thanx, Rizwan Ahmed Tag: 1.1 Framework and IIS Tag: 56843

    - TcpClient lost data timing anomaly Hi The platform: XP/pro on a dual Xeon 3GH processors I am using TcpClient class to communicate with a POP3 server. Short problem synopsis: a 'read' hangs even though there is data in the buffer (as evidenced by a network sniffer trace). Elaboration: I/O is done by getting the NetworkStream and doing a read for a whole buffer's worth (typically 1024) of bytes. The code looks for the NL (new-line char, '\n'), as a delimiter. If found, the text up to and including the NL is returned to the caller. Otherwise another read is performed and concatenated to the previous read's output, and the check for the delimiter repeats. On subsequent reads, if there was data left over from the previous read, it is processed for NL before any other reads are issued. I have used a network sniffer to determine that all the data is coming in. I have put a trace in my program to output to a file (serialized with a 'lock') all the output form all the read requests. I consistently find that one of the reads is able to get all but the last 3 bytes of a response from a server. The code dutifully returns all the text received and tries to do another read since the caller is looking for a '.\r\n' sequence (end-of-message). This read hangs (I use the debugger). When I change the buffer size the problem happens in a different message. If I make the buffer large enough, the problem goes away. The buffering code described above is working for thousands of messages that have split across multiple buffers or for short messages where multiple fit in the same buffer, so I'm pretty confident that it is splitting messages correctly and gluing together segments across network messages. My only conclusion is that something in the TcpClient (or deeper) is checking the socket and waiting for more data in a non-atomic manner. The problem shows up on my system because it is a fast dual processor system that can obviously do concurrent processing by multiple threads/processes. Has any one seen this kind of problem before? Any work-around? -TIA David Tag: 1.1 Framework and IIS Tag: 56822

    - Problems with GCHandle and AppDomains Greetings everyone. I am currently working on a multimedia application written in unmanaged code. As part on my next set of improvements, I would like to host the CLR in the application and allow third parties to extend the application and manipulate internal objects in the application through a "script" interop layer I provide written (on my end) in managed C++. The way my system is set up, from the default domain in my host, I instantiate the script harness using AppDomain::CreateInstanceAndUnwrap method and downcast the resulting object to a common interface that my application and the harness know about. I call a "run" method on the interface. In a test script I created, I register a callback object into the multimedia app. The unmanaged callback object contains a GCHandle to a delegate which it fires periodically on behalf of the unmanaged application based on certain timing parameters. Now, when the harness and my test script used to run in the default domain, everything worked like a champ. Now that the test script is in a different domain, when the unmanaged callback object dereferences the gchandle to invoke the delegate on the script, I get an ArgumentException with a description that reads: "Cannot pass a GCHandle across app domains". I've hit my head against the wall trying to get this to work for a while now with no success. Does anyone have any idea what I could be doing wrong? Thanks in advance for any help you can give.

    - Localization and multiple string resources Hello! I am looking at .Net localization. I happen to be using J# with VS 2003 but it could be any supported language. The LocalizedHelloWorld example from MSDN and VS shows how to localize a single .resources file. Here is a link to the J# version: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dv_vjsample/html/vjsamlocalizedhelloworldsamplesatelliteassembliesforconsoleapplications.asp The problem I have is I am working with an application that has several string resources per DLL. I have not been able to find a way to get it to work. The example loads a resource called "HelloWorld.Resources.MyResources". Each localized version is embedded in a DLL called "HelloWorld.resources.DLL". The trick seems to be that there can be only one such DLL. I have modified this sample and tried embedding two resources, MyResources.resources and MyResources2.resources, and also creating, for example, two French resources, MyResources.fr.resources and MyResources2.fr.resources, into the satellite assembly "HelloWorld.resources.DLL". But, when I request "HelloWorld.Resources.MyResources2" with the culture set to "fr", it fails to find the second French resource and falls back to the embedded MyResources2.resources. Does anyone know a way to make this work? Thanks in advance. Tag: 1.1 Framework and IIS Tag: 56803

Hi,

I'm having some strange problems with 1.1 Framework and
IIS. When I installed this on my machine IIS didn't
register .aspx, .asmx etc etc as running through the
aspnet_isapi.dll, so I ran the aspnet_regiis.exe to fix
this but then a strange thing happens. If I now create a
new virtual directory pointing to an existing app which I
know for sure works it will take up to 1 hour to open the
web page, it just sits there forever. Once the page has
opened once it works fine.

I thought something must have gone wrong in the install
but several people I know have had this problem but no
one has a fix, any ideas?

I have heard of a similar problem while waiting for "Initializing
offline cache". For some users, it does come back after a while. For me,
in one new installation of .net. it never comes back and the IDE
eventually aborts.
