    - Loss message in Socket Async mode Hi, all Did not find a .Net Communication forum to post. I am soing a client/server message system and using C#.net socket and Async mode. Pretty much as described in article http://www.developerfusion.co.uk/show/3997/3/ But I have a big issue with this approach and I am not what did I do wrong. the client send message so quick that when I loss the second message. I need to call endReceive in my Callback function and process the first message, now the second message is arrived and since I have not call beginReceive, then, I loss the second message. Am I doing wrong or is that unavoidable? Thanks in advance -rockdale -------------------------------------------------------------- source code from the article is attached. byte[] m_DataBuffer = new byte [1024]; IAsyncResult m_asynResult; public AsyncCallback pfnCallBack ; public Socket m_socClient; // create the socket... public void OnConnect() { m_socClient = new Socket (AddressFamily.InterNetwork,SocketType.Stream ,ProtocolType.Tcp ); // get the remote IP address...

    - problems with xmlserializer on domain machine Hello. I have developed an application (an office addin).The application works fine with no error messages on my devoping machine (that machine is not connected to any domains). I have problems getting this application to run on a computer where the user is on a domain (as in a big company where you log on to the company domain). The funny thing is that the application works fine in outlook. But not in word or excel... The error occurs when trying to create the proxy object. This proxy objects creates successfully when run from outlook. The stack trace from my error is as follows: at System.IO._Error.WinIOError(Int32 errorCode, String maybeFullPath) at System.IO.FileStream.Init(String path, FileMode mode, FileAccess access, Int32 rights, Boolean useRights, FileShare share, Int32 bufferSize, FileOptions options, SECURITY_ATTRIBUTES secAttrs, String msgPath, Boolean bFromProxy) at System.IO.FileStream..ctor(String path, FileMode mode, FileAccess access) at System.IO.FileStream.Compiler.TempFileCollection.EnsureTempNameCreated() at System.IO.FileStream.Compiler.TempFileCollection.AddExtension(String fileExtension, Boolean keepFile) at System.IO.FileStream.Compiler.TempFileCollection.AddExtension(String fileExtension) at Microsoft.CSharp.CSharpCodeGenerator.System.CodeDom.Compiler.ICodeCompiler.CompileAssemblyFromSourceBatch(CompilerParameters options, String[] sources) at System.codeDom.Compiler.CodeDomProvider.CompileAssemblyFromSource(CompilerParameters options, String[] sources) at System.Xml.Serialization.TEmpAssembly.GenerateAssembly(XmlMapping[] xmlMappings, Type[] types, String defaultNamespace, Evidence evidence, CompilerParameters parameters, Assembly assembly, Hashtable assemblies) at System.Xml.Serialization.TempAssembly..ctor(XmlMapping[] xmlMappings, Type[] types, String defaultNAmespace, String location, Evidence evidence) at System.Xml.Serialization.XmlSerializer.FromMappings(XmlMapping[] mappings, Type type) at System.Web.Services.Protocols.SoapClientType..ctor(Type type) at System.Web.Services.Protocols.SoapHttpClientProtocol..ctor() After reading several posts on the internet I found something about calling the XmlSerializer could create problems. This because it has to compile code and has to make a temporary file to write to. Is there anything is this lead or are ther other things that may cause my problems? I'll be very happy for any hints or tips you can give me :) Tag: Error 4786 with Windows Service Tag: 124477

    - Call "Sub Main" in (WPF) XAML-Application? I have installed Framework 3.0 and Visual Studio 2005 extensions for .NET Framework 3.0 (WCF & WPF), November 2006 CTP. If I make a new WindowsApplication the StartupObject is not set. But the Application starts with Window1.xaml If set the StartupObject to "Sub Main" What more must I do that I can start the Application with the "Sub Main". Or in other words, how can start my Application first with a Custom Methode where I can define the Window-XAML to show? Best regards Horst Tag: Error 4786 with Windows Service Tag: 124471

    - Application terminates due to access violation? Does anyone knows the meaning with KB823140 and KB903886? These articles treat the issue of "Access Voilation" in .NET framework. I have an application developed in C# that sometimes simply dies. No messages, no error codes, no exceptions. A few days ago I got a tip that this might be caused by an "Access Violation" when calling methods in COM components. Daniel Tag: Error 4786 with Windows Service Tag: 124469

    - Bug: Localization for Button Control in inherited UserControl Hi everyone, After trying to make this work for a while I didn't get a chance to obtain what i was supposed to, so here is the description of the bug (I think) I found : Steps to reproduce : 1. Create a new Windows Application project. 2. Create a UserControl (ex: UCMenu) and set it to localizable in design time. 3. Put one Label and one Button on it(ex. name: buttonToLook), set on them different Text properties values depending on languages (ex: (default) & fr). 4. Expose Text properties of all 4 controls with localizable attribute on it ([Localizable(true)]). 4. Create a UserControl (ex. name: UCInheritedUCMenu) inheriting from UCMenu, set it to localizable in design time. 5. Put UCInheritedUCMenu on the project main form (and set form also to Localizable). 6. In Program.cs, set Thread.CurrentThread.CurrentUICulture to "fr". 7. Run the application and notice that only buttonToLook does not take its localisable value (you can add other controls on UCInheritedUCMenu or form to see that only buttonToLook is not localized). 8. Comment Text property exposure for buttonToLook and run the application again : text of button is now localized. Thanks for all your help. Hope You'll give a correction for this :-) Tag: Error 4786 with Windows Service Tag: 124465

    - an existing connection was forcibly closed by the remote host Hello, I am developing an HTTP/1.1 proxy server in c#.net. I am encountering the following exception when I try to send the response body back to the client: "An existing connection was forcibly closed by the remote host". This exception is thrown by the Socket.Send() method (where the specific socket in this case is the client socket).

    - Handling unknown elements with a ConfigurationElement Hi, Since the IConfigurationSectionHandler interface has been deprecated since the introduction of .NET 2.0, I'm trying to use the new configuration classes to handle a custom configuration section. I've gone through all the samples and MSDN docs, but none of them answer my question. What is specific (I think) is that I want to have a child element that is not known until runtime: <processingService> <processes> <process name="Process1" type="SomeNamespace.Process1, SomeAssembly"> ....elements specific to the Process1 class </process> <process name="Process2" type="SomeNamespace.Process2, SomeAssembly"> ....elements specific to the Process2 class </process> </processes> </processingService> Essentially, I want to allow each <process> element to have some child elements only known by the class that it refers to (e.g. Process1). I've defined the ConfigurationSection, ConfigurationElementCollection, ConfigurationElements and ConfigurationProperties as it should, and everything works fine until I add some arbitrary child elements. The configuration framework then throws an exception resulting from the unrecognized elements. As a workaround, I can prevent that exception by overriding the OnDeserializeUnrecognizedElement method of the ConfigurationElement that represents the <process> element. I can even extract the child XML and store it somewhere. But with that, I want to be able to deserialize that XML to a ConfigurationElement subclass provided by the ProcessX class (because they are the only ones who should know what that XML means). Unfortunately, there is no method or interface I can find to manually serialize some XML to a ConfigurationElement subclass. Question 1: What is the preferred way of dealing with unknown child elements in .NET 2.0? Question 2: How can I programmatically (de)serialize XML to/from a ConfigurationElement subclass which has properties that have [ConfigurationProperty] attributes on them.

    - How can I use Regasm on server? Hello all. I have an assembly that needs to be registered on a server for use with SQL Server 2k. Locally I can run Regasm from the VS.NET command window and that's that. But how can I get the assembly registered on the (or any) server? I have the dll, snk...all that, but I can't figure out how to register the thing so my procs don't return the "Invalid Class String" error (for lack of a ProgID)?

    - IO.Compression and Encryption Hi, Environment: VB 2005 Professional Both ends, its the application which is doing the functionalities. At the despatch end, We have a text file which is to be compressed and encrypted and sent over to the recepient. At the recepient end, the file is decrypted and then decompressed. Say the original file is CreateTestPort3.txt CreateTestPort3.txt: 1306 KB (original file) TestGZipped:151 KB (compressing the original file using GZipStream) EncryptText:151 KB (encrypting the compressed file) DecryptText: 76 KB (decrypting the earlier file) CreateTestPort3GOriginal: 0 KB (decompressing the file) We receive an error at this stage: Error : An unhandled exception of type 'System.IO.InvalidDataException' occurred in System.dll Additional information: The magic number in GZip header is not correct. Make sure you are passing in a GZip stream. Can anyone point out what are we doing wrong? If we just compress and decompress the file using the same code, its perfect. If we encrypt and decrypt the file using the same class, its perfect. But if we do the combination of compression and encryption, the file is totally messed up. Any reasons? For the sake of testing, we did both the functionalities of recepient and despatch end in the same project...

    - Framework files location for compile On our development machines I created some batch file for compiling our web apps. They make use of some environment variables and batch files that visual studio installs. if "%VS80COMNTOOLS%"=="" goto error_no_VS80COMNTOOLS rem set path of aspnet_compiler for the framework in vs80 call "%VS80COMNTOOLS%vsvars32.bat" On my machine VS80COMNTOOLS=C:\Program Files\Microsoft Visual Studio 8\Common7\Tools\ vsvars32.bat sets a lot of environment stuff but, basically it puts into the path the location of aspnet_compiler and aspnet_regiis This is great because I don't have to hard code the path or worry about new paths if the framework gets upgraded. Unfortunately, I now need to compile on a computer which does not have VS installed. Thus no environment variables or vsvars32.bat file. Is their an automated way to get the most recent path to aspnet_compiler and aspnet_regiis? thanks, Tag: Error 4786 with Windows Service Tag: 124419

    - .Net 3.0 Administrative Setup .Net 3.0 deployment via Active Directory and Group Policy seems pretty broken to me. The most up to date info I can find is in the RTM SDK under 'Microsoft .NET Framework 3.0 Administrator Deployment Guide'. The script at the bottom of that article ignores the WIC and XPS components of dotnetfx3.exe and the command to extract wcf.exe does not work. WCF.exe /? indicates there is no /c switch for wcf.exe. Could someone from MS have a look at this and provide a working script or other instructions on how to deploy with Group Policy? Thanks Michael Tag: Error 4786 with Windows Service Tag: 124403

    - OE - nothing appears in message body I've been using Outlook Express for my Hotmail account for a long time. Suddenly it isn't working properly. It downloads messages into the inbox fine, but for some reason when I open a message I get the hourglass and no matter how long I wait nothing appears in the body of the message. I tried accessing the same hotmail account via OE on another computer and it works fine, so the problem is specific to the OE on this one computer. By coincidence I had downloaded IE7 the day this started happening, but I can't remember exactly if the problem started before or after the IE7 download. Any idea what is wrong and how to fix it? I've tried deleting and recreating the account in OE. That did no good. By the way, why isn't there an OE7 with IE7? My OE is still version 6. Tag: Error 4786 with Windows Service Tag: 124398

    - TypeConverter and arrays Using asp.net1.1, I have a property on a control that is an enum. I use an accessor and set it in HTML view. So: public enum Permission { None = 0, Admin = 1, Member = 2, ... } ... public class Lock : System.Web.UI.Control { private Permission perm; [Bindable(true), Category("Security"), DefaultValue("1")] public Permission RequiredPermission { get { return perm; } set { perm = value; } } Then in html view: <cc1:Lock ... RequiredPermission="Admin" ... > Now, I want to make the Permission property an array of permissions: private Permission[] perm; My question is, how can I implement this to allow me to still specify the list of permissions in html view, like: <cc1:Lock ... RequiredPermission="Admin,Member" ... > I need to convert this list into an array, is there any way to do this within an accessor? If I try something like this, I get a parser error, saying it can't create an object of type Permission[] from its string representation. public Camelot.Permission[] RequiredPermission { get { return perm; } set { // break up comma delimited string in value, create an array of permissions, assign it to perm } } Thanks!

    - ClickOnce Deployment on Thin Clients for ALL users I am having a bit of a problem with my ClickOnce Deployment strategy for vb.net 2005 apps. I am working in a plant which has hundreds of thin clients and when I deploy an app using ClickOnce, it asks each individual user if they want to install. When updates are rolled out, it then asks each user if they want to get the newest version. Is there a way to deploy my apps globally to the terminal server instead of having to deploy to each individual session. I.E. Install at the Machine level and not the User level so that users are not bothered with the install / update question?

    - Application.ThreadException not working Hi, I have a shoddily written application that is written in 1.1 that I've ported to 2.0 and now occasionaly I get crashes which I suspect are been caused by exceptions in threads, most likely due to trying to access controls which is now stricter, I know I could just set CheckForIllegalCrossThreadCalls = false; But I'd rather like to understand a bit better about ways to handle these exceptions and diagnose them so have been playing with "Application.ThreadException" and "AppDomain.CurrentDomain.UnhandledException", the problem I have is "Application.ThreadException" never seems to fire and this is cunfusing the hell out of me. I have the following simple test code using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Text; using System.Threading; using System.Windows.Forms; namespace TestApp { public partial class Form1 : Form { public Form1() { InitializeComponent(); Application.ThreadException += new ThreadExceptionEventHandler(Application_ThreadException); AppDomain.CurrentDomain.UnhandledException += new UnhandledExceptionEventHandler(CurrentDomain_UnhandledException); } void CurrentDomain_UnhandledException(object sender, UnhandledExceptionEventArgs e) { MessageBox.Show("CurrentDomain_UnhandledException " + e.ExceptionObject.ToString()); } void Application_ThreadException(object sender, ThreadExceptionEventArgs e) { MessageBox.Show("Application_ThreadException"); } private void exceptionButton_Click(object sender, EventArgs e) { Thread t = new Thread(delegate() { int zero = 0; int x = 1 / zero; }); t.IsBackground = true; t.Start(); } private void crossThread_Click(object sender, EventArgs e) { Thread t = new Thread(delegate() { crossThread.Text = "Error"; }); t.IsBackground = true; t.Start(); } } } Which is just a windows form that has 2 buttons, crossThreadButton & exceptionButton, crossThreadButton simply creates a thread that tries to access a control it shouldn't, and exceptionButton simply divides by 0 to create a exception, both cause the "AppDomain.CurrentDomain.UnhandledException" event to be fired, but niether cause the "Application.ThreadException" event to be fired which is confusing me. When should "Application.ThreadException" get called, am I missing a setting or is it only for specific situations. Also is there a way to prevent the application from exiting when there is a exception in a thread and "AppDomain.CurrentDomain.UnhandledException" is fired, In my main shoddy app I'm 99.99% sure that exceptions in threads that have a long lifetime are handled and that these problems are been caused in shortlived threads that if they fail the work will simply be picked up on the next iteration, there is a reasonable amount of manual work involved in setting up and configuring the app and loosing all this is a pain for the user, if they could be informed of the error but allowed to continue that would be a lot easier for me while I find all the causes of the problem.

    - TimeZone.CurrentTimeZone doesn't update I'm seeing TimeZone.CurrentTimeZone accurately reflecting the machine time zone at the point that the assembly loads, but if the user subsequently changes the Windows time zone the value of TimeZone.CurrentTimeZone doesnâ??t change to reflect that. In other words, if the system is on PST when my assembly loads then whenever time I instantiate a TimeZone object (System.TimeZone tz = System.TimeZone.CurrentTimeZone;) the value of tz.StandardName returns "Pacific Standard Time" and tz.GetUtcOffset comes back as -08:00:00 - even if I change to Brisbane time (+10:00:00) Is there some trick to this that I'm missing? I've got an Outlook add-in that's passing date values to a web service. Even though it works in UTC internally, the SOAP proxy classes expect values in local time to which the parser then assigns an offset. The conversions to and from UTC continue to use the original offset even if the user changes time zones, which corrupts the data. Tag: Error 4786 with Windows Service Tag: 124380

    - Bound ComboBox for browsing _and_ editing? Can I use a bound ComboBox for both browsing and editing? I'm working on a small, standalone database application using Visual C#.NET 2003 and an Access data file. In order to keep the number of different screens down to a minimum, I'm trying to use the same Windows Forms for both browsing and for updating. This works fine for TextBoxes, but I'm running into problems with my DropDownLists (ComboBoxes). Thre's nothing special about the (string) lists in these ComboBoxes. They're set up with DisplayMember="" and ValueMember="", they're defined inside the VS Designer, and they're a convenience to save the user from having to remember what the valid choices are; the choice, once made, would simply be stored into a text field... er, column. Or, at least, that's how I thought/hoped it would work. Trouble is, I can't figure out how to bind these ComboBoxes in a way that lets the user see the existing values as they browse with the bound TextBoxes and ComboBoxes disabled (Enabled=false), yet allows editing when these same controls are enabled. Binding my DataView to the ComboBoxs' "Text" property is tempting. It works very nicely for browsing; the current contents of the data columns are displayed properly as the user "scrolls" through the rows. When the control is enabled (for editing), the DropDownList displays properly, a choice can be made, and all appears well... until I attempt to update the database. According to the debugger, the controls _are_ bound, and a changed ComboBox _does_ have new (changed) contents in its Text property, but the supposedly bound data column never gets updated (again, per the debugger's display of my DataView with DataView.RowStateFilter = CurrentRows). (TextBoxes bound to the same DataView are working just fine.) Then there's binding to the ComboBox's SelectedValue Property (or possibly its SelectedItem -- even after reading the online documentation I'm not really sure what the difference is between these two). I tried this, but I lose the "browsing" feature -- when the ComboBox is disabled all that shows is either blanks or the last choice made when the control _was_ enabled. Late this afternoon, after spending another couple of hours with Google trying to find the keywords for a magical incantation that would take me directly to an explanation of this problem and a workaround -- and failing -- I tried something only moderately perverted: I bound the ComboBoxes' Text property and installed an event handler for their SelectionChangeCommitted events. My first attempt forcibly altered the Text property: private void cbx1_SelectionChangeCommitted(object sender, System.EventArgs e) { // Warning: reconstructed from memory ComboBox cbx = sender as ComboBox; string s = cbx.Text; cbx.Text = ""; cbx.Text = s; } Then I tried something that _seemed_ a little less klugy: private void cbx1_SelectionChangeCommitted(object sender, System.EventArgs e) { // Chose a new velue? ComboBox cbx; cbx = sender as ComboBox; cbx.Text = cbx.SelectedValue.ToString(); } This one works... mostly. It occasionally throws a "null reference" exception complaining that, in spite of the fact that the code is in an event handler set up for the case that a selection has been made, cbx.SelectedValue lacks a value. SelectedIndex: 1 selectedIndex: -1 SelectedItem: "Option 2" (second string from list) selectedValueChangedFired: true and the embedded ListControl has: SelectedIndex = 1 SelectedValue = <undefined value> (a.k.a. "Ka-boom!") I can't be the first person to ever try setting up a form with ComboBoxes to browse and edit a database. I keep feeling that I'm missing something simple, something that's so obvious to everyone that no-one bothers mentioning it. I did run across a note about VisualBasic ComboBoxes in the VS online documentation that might be relevant entitled: Data binding for ComboBox or ListBox is read-only but (a) it's not clear whether or not this note applies to VC#, and (b) the note's rather terse workaround merely says to Add code to the ListControl.SelectedValueChanged event for the ComboBox or ListBox controls to update the database. without providing any specifics. It's very frustrating: with the VS debugger I can see the ComboBox selection being stored into its Text property, but I can't seem to home in on where the ball gets dropped, that is, what stops that value from being stuffed into the DataView's current DataRow. Has anyone out there been down this road before? I'm hoping someone familiar with binding and ComboBoxes can either tell me that I'm going at the problem from a completely wrong direction, or possibly that my horribly ugly code is about the only way to accomplish what I'm trying to do. Any hints, suggestions, or clues will be appreciated.

    - DataGridView in 2.0 Framework - Sorting All, I am having a considerable amount of difficulty with what should be a very simple problem. I have a DataGridView that is bound to a collection of objects that displays (and edits) selected objects appropriately. However, I can find no way to activate sorting by column. I want to be able to do the normal thing: click on a column and have the rows sort (alphabetically) according to the contents of the selected column. According to the documentation, I should be able to set the column's sort mode to "Automatic" and the sort glyph should become available on the column. This, however, does not happen.

    - html help files (chm) and .NET framework 2.0 Hi, I work on a large application (relative I guess) and the help is implemented in a CHM file converted from a Word file. For the version of the app pending release one of the things done was to upgrade to .NET 2.0. As a result it seems that pressing F1, whilst bring the help up, if you click any related links displayed on any of the pages then after a short period of the Windows help chm viewer being unresponsive it generates an out-of-memory error and clicking [ok] closes both the help and the application. My reason for suspecting this is due to the following investigation: 1) Doc-To-Help forum (product being used to convert Word file to help chm file) some one has virtually identical problem (except they don't get the message and the closure, just no links work). The single response was that it was a .NET 2.0 framework issue. 2) If I launch the CHM from Windows explorer then links work fine. 3) If I copy the help file to the install directory of the previous version of our app (which uses .NET 1.1) and launch the help from the previous version then links work fine.

RE: Error 4786 with Windows Service by CiaranODonnell

The exception is an access violation which appears to be occuring from COM. I
dont know what the IDispenserDriver is so I assume it is something you have
coded.
I found some explanations of the problem here:
http://www.eventid.net/display.asp?eventid=4786&eventno=3412&source=COM+&phase=1

It depends on what your actually doing as to what the cause could be. An
access violation is the same as a NullReferenceException in .NET. It can be
be caused by almost anything although in a .NET app it must be a COM interop
as the framework turns them into NRE's when it encounters them.
