    - Problem Using XmlElement(Order:=...

    - How to get the folder name for the Windows recycle bin? Bearing in mind the Windows recycle bin folder has had 3 names since Win 95 up to Vista: x:\RECYCLED (95, 98) x:\RECYCLER (NT, XP, 2000, 2003) x:\$Recycle.bin (Vista) Consider iterating through the the root folder of a drive, and excluding the recycle bin from your results. It is unacceptable to simply ignore folders named "RECYCLED", "RECYCLER" or "$Recycle.bin" by string comparison because, for example, a Vista user may have created their own "Recycled" folder. Is there a set of constants for these folders, or a way of discovering the recycle bin folder for a given volume in .NET? Consider too that the drive might not be local, and may be accessed remotely by system share (e.g. \\machine\C$\) Boz Tag: Use C# assembly in MFC - help Tag: 128323

    - UriFormatException from WSE in 2.0, not in 1.1 (need help) I'm developing an ASP.NET 2.0 site wich uses some 1.1 assemblies built by our team (server and win client is still 1.1, web is 2.0). The problem is that my use of thiese assemblies - wich uses WSE 2.0 SP3 - suddenly throws an exception. We can't find any code changes that should cause this. The exception is: System.UriFormatException: Invalid URI: The Authority/Host could not be parsed. at System.Uri.CreateThis(String uri, Boolean dontEscape, UriKind uriKind) at System.Uri..ctor(String uriString) at Microsoft.Web.Services2.WebServicesClientProtocol.set_Url(String value) I have varified that the URI supplied is valid. I have also created two test websites, one in .net 1.1 and on in 2.0, running the exact same code as the problem website, and now I find that while the 2.0 test still fails the 1.1 works fine. The exception occurs when creating a WSE proxy for making web service calls to our web services. But there are very similar calls already made before this exception happens. I'm really at a loss here.., we're trying to set up differen testing environments, but nothing has given us any clues yet. The site/code worked fine two days ago, then it stopped working.., what should I do? Anyone?? Is it a problem with using WSE 2.0.3.0 for .net 1.1 under the 2.0 framework? Any workarounds?

    - FileStream.Close() Exception - How to release the lock? Hello! Using .NET v2.0.50727, I've attached some sample code that creates a file in a network path (test.er-1): - The file is created at a network path. - The user disconnects his/her network cable. - The file is attempted to write to. - The user reconnects his/her network cable. - The file is closed - WHICH fails and results in the exception "The handle is invalid" This results in that the filelock remain active until the process is terminated...

    - Jit 64bit Hi all, my team developed an application that partly is .net and uses a win32 dll that we don't want to port to 64 bit. We compiled the .net part of the application telling the compiler to output x86 code. The application doesn't seem to work well anyway since some external assembly doesn't work like expected on WIN2003 x64. I think this external assembly are jitted to 64bit. Can we force the jit of all the program to x86 code? TIA Marco Tag: Use C# assembly in MFC - help Tag: 128301

    - System.Transaction and MSDTC We are developing a .NET 2.0 based distributed application and use System.Transaction namespace to handle transaction at Business Object level. DAAB 2.0 is used at Data Access Layer level. The database is SQL server 2000 (installed in Windows 2000 server). The .NET server components are deployed in Windows 2003 server. When we attempt to run the application, it throws exception saying â??DTCâ?? service is not running. We are not sure why DTC is a prerequisite for System.Transaction which defeats the purpose of choosing the same. We have also customized the DAAB not to close the connection when the transaction scope is alive but it does not help (This is implemented based on DAAB 3.0). Will system.transaction use DTC by default with SQL server 2000? If so, is DTC a prerequisite in this scenario? There are few articles states SQL 2005 will not require DTC. Any supporting links or inputs on this would help us. Appreciate your help. Thanks and Regards Rasheed Tag: Use C# assembly in MFC - help Tag: 128296

    - ReadOnlyCollection and Multiple Threads I've been really leveraging the ReadOnlyCollection class the last few weeks, figuring that it works exactly as it's name describes. Yesterday I was rudely reminded that reading the documentation for a class is very important, and that making silly assumptions is also bad. It turns out the ReadOnlyCollection isn't readonly at all, and that iterating over it isn't a good thing. I looked all over the Web and various Newsgroups for other people who have run across this, and all of the examples I found were wrong. Many, many people have made the same mistake that I did. http://www.coversant.com/Default.aspx?tabid=88&EntryID=34 In a nutshell: The ReadOnlyCollection class is not thread safe. If a different thread changes the underlying IList<T> then the contents of the ReadOnlyCollection change, and all of the standard threading problems arise. The Documentation says exactly this, so it's simply a case of failing to RTFM. -- Chris Mullins, MCSD.NET, MCPD:Enterprise, Microsoft C# MVP http://www.coversant.com/blogs/cmullins Tag: Use C# assembly in MFC - help Tag: 128276

    - Another Thread Safety Question Hypothetical question: A multi-threaded app has an object with a privately scoped collection (like ArrayList) that is shared between threads. The model is one thread creates/reads/writes/updates the collection, and all other threads read the collection. What are the minimal locks required for thread safety? Is it safe to only lock access when writing/updating the collection? Is it overkill to lock access for all access (including shalllow-copy instance cloning and read-only) in the properties/methods exposed by this object? Tag: Use C# assembly in MFC - help Tag: 128264

    - =?Utf-8?Q?Using_=E2=80=98non_true_type_fonts=E2=80=99_in_d?= I am in the process of upgrading the old legacy application to dotnet 2005 windows application. This is a graphical windows application with various shapes and text strings being put on the bitmap and printed. The problem I am having is, because of the fact that the old legacy system used lots of fonts with custom widths and weight and since dotnet GDI plus does not allowing using â??Non standard fontsâ??. I am kind of stuck at this point. I do not know if any of the below would solve the problem or any other suggestions out there? 1) Create a font using API to GDI and use the Font generated in the dotnet environment. But when tried this approach I got the error message â??Only TTF fonts supportedâ??. So looks like not possible. 2) Create the equivalent TTF fonts for all legacy fonts used and use them in dotnet application. 3) Create an ActiveX on VB6 which returns the equivalent bitmap with the required text and use it in my dotnet application. But not sure what other options I have. Any suggestions are greatly appreciated Tag: Use C# assembly in MFC - help Tag: 128252

    - MsBuild lost some imported namespaces? Hello, I have medium-sized solution in VB.NET (70 000 lines). The project compiles ok under VS2005, without any errors, without any warnings. But when I compile the same solution under MSBuild (from command line), strange things happenes. Compiler executed by MsBuild reports unknown types where it should by known. After whole day of investigation is have found, that imported namespaces are randomly "lost". For example, there is clause Imports System.Windows.Forms in the class file header. But compiler reports DialogResult as unknown type in the same file. When I change declaration of DialogResult to System.Windows.Forms.DialogResult, all is compiled Ok. I must to do these changes 29x in the project. My question is why? It is _exactly_ the same project, which compiles ok in VS2005. The compile line for Vbc.exe is exactly the same (compared from VS2005 build window and MSBuild log file). The build configuration is the same. Not every type from System.Windows.Forms is unknown. Nor System.Windows.Forms is the only one lost, there are similar problems with some of my namespaces.

    - How to monitor which app window is the foreground window? Hello, friends, I need to write an assembly (C#.net 2.0 class library) to monitor all applications currently running in a PC. Especially, I need to know which window is the top one, i.e., catch the event when a window becomes foreground window. Should I use WndProc() to catch related window messages? (I don't want to use timer). Any reference paper or sample source code? Thanks a lot. Tag: Use C# assembly in MFC - help Tag: 128229

    - Compact Framework Sockets Question I don't see a Compact Framework newsgroup so I am just going to post it here. We are porting a .NET 2.0 program to the compact framework and the application involves the sending and receiving of multicast packets. We noticed that even though the property Socket.MulticastLoopback exists in object browser under "System [Compact Framework]", it complains at compile time that 'System.Net.Sockets.Socket' does not contain a definition for 'MulticastLoopback' According to the MSDN documentation online, this property is supported by the compact framework and we are using the latest service pack of CF2.0. Any ideas? If this property is indeed not included in the CF, how might we configure the socket so that (we have already tried sock.SetSocketOption(SocketOptionLevel.IPv4, SocketOptionName.MulticastLoopback, 1); which throws during runtime) we can allow multicast packets to loop back?

When I instantiate this schema class and try to set a property on it, however, I get the following error: Object reference not set to an instance of an object.

    - ActiveDirectoryMembershipProvider Having trouble using ActiveDirectoryMembershipProvider with one specific website. When attempting to login to the site, after a long period of time (about 2 - 3 minutes), "Server Application Unavailable" message is returned. If I switch the provider back to SQLServer everything works fine. If I create a new simple Web Application and just add a Login.aspx page and Default.aspx page, and nothing else, and add a Login Control everything works fine. I successfully receive a formsauthentication ticket, etc.. I setup up the web.config file to use the ActiveDirectoryMembershipProvider and set the appropriate AD connection string (the same string in the first app used) and everything is fine. Differences between the two: The app that does not work uses a SqlRoleProvider, AzMan and SqlPersonlization. Could using any of these cause the problem and error message returned? Has anyone else had any issues connecting a large or complex website with AD using the ActiveDirectoryMembershipProvider? Thanks in advance.

    - Visual Studio 2003 and Javascript help... Hi, I'm using Visual Studio 2003 to develope a Web-form application. This application required me to do some Javascripting. Now my Javascrip is not exactly what you would good - I need lots of help and explanations etc... High levels of variable transparence etc. Because of this, I found the whole deugging routine quite difficult with VS2003 and Javascript. For example, the intelligent completion thingy works but does not provide an explanation of the methods etc... I was wondering is there a plug-in that can enhance VS2003's Javascript development ability? Any comments/suggestions/user-experiences much, much appreciated. Cheers & thanks Al.

    - following of thread: "Adding namespaces to code behind automatically" More options following of thread: "Adding namespaces to code behind automatically" Hello, I had quite the same problem and got further in the right direction with your suggestions, thanks. Nevertheless, I have a newer problem which seems to come from the fact that the assembly which contains my "SimpleComponentToolboxItem" must be already referenced in the project where I want to insert my control. I have a usercontrol, which uses a TagListViewToolboxItem and its CreateComponentsCore method to reference other assemblies to the project where I insert my control. like this: (In the library xyz.dll) [System.ComponentModel.ToolboxItem(false)] [Serializable] public class MYTagListViewToolboxItem : ToolboxItem { /// <summary>Not used...</summary> public MyTagListViewToolboxItem() : base() { } private MyTagListViewToolboxItem(SerializationInfo info, StreamingContext context) : base(typeof(MyControls.MyTagListView)) { Deserialize(info, context); } protected override IComponent[] CreateComponentsCore(IDesignerHost host) { MessageBox.Show("1"); ITypeResolutionService service1; IComponent component1; IComponent[] componentArray1; IContainer container1 = host.Container; service1 = ((ITypeResolutionService)host.GetService(typeof(ITypeResolutionService))); string assPath = "C:\\MyAssemblies"; string ass1Name = assPath + "\\log4net.dll"; string ass2Name = assPath + "\\Util.dll"; System.Reflection.Assembly ass1 = System.Reflection.Assembly.LoadFrom(ass1Name); System.Reflection.Assembly ass2 = System.Reflection.Assembly.LoadFrom(ass2Name); service1.ReferenceAssembly(ass1.GetName()); service1.ReferenceAssembly(ass2.GetName()); component1 = (IComponent)System.Activator.CreateInstance(Type.GetType(this.TypeName)); container1.Add(component1); componentArray1 = new IComponent[] { component1 }; return componentArray1; } } I have the assembly loaded in the VS8 Toolbox and this implementation works fine when the project where I want to drag-and-drop the MyTagListView control already has a reference to my library xyz.dll, which contains my toolboxitem class. But if the project does not already reference the xyz.dll assembly, I get the following error while trying to insert my control on the form: "Failed to create component 'Component'. The error message follows: 'The toolbox item could not be retrieved from the toolbox. Make sure the assembly that contains the toolbox item is correctly installed. The toolbox item raised the following error: Object reference not set to an instance of an object." ... and my control is not inserted. I thought that this was because the control type set in the private constructor was not known by the project. But then I have replaced my MyTagListView control to a normal Button control (still in this private constructor, and the problem still occured. This tells me that the assembly which contains my toolboxitem MUST be referenced in the project before being able to use the control from the toolbox. I have also put some messagebox in the private method, and found out that having just the mouse over the toolboxitem of my control will instanciate my toolboxitem. If this cannot be fixed, it means that I absolutely need to reference my xyz.dll assembly to the project before being allowed to insert my controls in the form. I have tried many things, and I must say that I am short of arguments... . Thank you in advance for your help, Jean-Francois Tag: Use C# assembly in MFC - help Tag: 128185

    - New Probing Rules for 2.0? I have a WinForms application that comprises files similar to this: a.exe b.dll c.dll The application is hosted on a Unix-based web server (case sensitive) and is accessed via HTTP ("no touch") deployment. For .NET 1.1, the probing rules required that the libraries all have upper-case "DLL" extensions, but the exe could remain lower-case. After upgrading to .NET 2.0, however, the probing fails, because the fusion process cannot locate "a.exe". Requesting "a.EXE" works fine, so I'm looking for confirmation that .NET 2.0 included this breaking change. Another byproduct of this is that the config file must also be renamed to "a.EXE.config", instead of the original (lower-case) "a.exe.config".

    - Socket Bugs on trying to send to disconnected clients I just made a simple TCP server to experiment socket exception when I lost the connection with my client. In this test program I create a socket and wait for a client (a basic telnet on another computer of my LAN) to connect. When the client is well connected, I unplug the ethernet wire of the client and I wait for exception. I thought that I will have an exception the next time I try to use the socket to send or receive data. So I try to send data to the disconnected client and the send call directly return to me that all bytes have been sent !!! Moreover, I check after the socket.Connected Boolean and it's True. I find some clues on this article : http://dam.mellis.org/2004/08/net_socket_bugs_gotchas/ This is my server code : Imports System Imports System.Net Imports System.Net.Sockets Imports System.Text Public Class Form1 Dim port As Integer = 10000 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim sckListening As Socket Dim sckClient As Socket sckListening = New Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp) sckListening.Bind(New IPEndPoint(IPAddress.Any, port)) sckListening.Listen(5) System.Console.WriteLine("Socket en Ã©coute sur " & sckListening.LocalEndPoint.ToString) sckClient = sckListening.Accept() System.Console.WriteLine("Serveur: Connexion acceptÃ©e avec " & sckClient.RemoteEndPoint.ToString) 'I try tu use the SendTimeout param sckClient.SendTimeout = 1000 'Here we sleep during 50 sec 'Between each sleep we check the socket.Connected var Dim i As Integer For i = 0 To 9 System.Console.WriteLine("Attente de plantage ...

    - Asynchronous delegate vs thread pool & thread This is quite an issue for me when doing debugging for async delegate call (i.e., using BeginInvoke). Note this is NOT Control.BeginInvoke, which runs on the thread creates the control. According to MSDN: If the BeginInvoke method is called, the common language runtime (CLR) will queue the request and return immediately to the caller. The target method will be called on a thread from the thread pool. SO it comes to Q1: is this thread pool the same one as System.Threading.ThreadPool? What if I have used System.Threading.ThreadPool to its full capacity and there is no more free thread available there? Will the BeginInvoke be blocked there? If so, the design of async delegate has problem. Also, since thread and thread pool is already there in the framework, what is the necessity of the existence of asycn delegate then? Or what is the difference between them? Thanks in advance. I have been puzzled by above questions for quite some time. Tag: Use C# assembly in MFC - help Tag: 128168

Hi

I want to retrofit a C# class library assembly into legacy MFC C++
applications. The application projects are VS2005 or VS2003 projects but
are unmanaged MFC C++ apps. I believe one approach is to enable COM
interoperability in the C# assembly and use it as a COM library in the
c++ app. Are there any other possible solutions without requiring
recoding of the c# modules etc or any major rework? Thanks!

You can add a C++/CLI class to a C++ project in VS 2005. Such a class can
directly interact with both managed C# assemblies and link with unmanaged C
and C++ compilation units.
