    - IsInRole from ASP.NET failing Hi All, I'm attempting to restrict access to my ASP.NET application using role based security. I'm using .NET v1.1 In code I check IsInRole for a local machine group, and it returns false. The name of the group is properly qualified with machine name in caps, and a forward slash (actually 2 'cause I'm using c# w/o @) and then the name of the group properly cased, yet it fails to find it. I found code on the internet that lets you see what groups IsInRole is checking against, and I do not see this group in there. I have 99 entries. I've tried a variety of tests like adding new groups that the user is a member of, removing group membership for groups the user is a member of, and nothing works. I still have 99 entries, and the groups that I remove the user from being a member of still appear in the list of groups the user is allegedly a member of. I've also tried rebooting the server, resetting IIS, clearing my temporary internet files cache, and nothing seems to make it work. I did check to see that IsInRole would be satisfied by providing a group that shows up in the group membership enumeration, and that does work. Anyone run into anything like this before or have any suggestions for me? Your help is appreciated! Tag: Registering VC# Express Offline?? Tag: 108728

    - Trace.Listeners questions A few questions about the Trace.Listeners. I was looking at the samples on MSDN, and wrote a small sample App. I used a TraceSwitch to determine the which messages I should print, and Added two trace listeners, one for a log file, and the other for the event log. The code works OK. First problem: For the EventLogTraceListener, all event log entries are coming out informational. I want some to have severity of error. Is there any built in facility for this, or does anyone have suggestions on how to get this effect? Second problem: In Java, I'm pretty sure that the equivolent trace facility has some kind of formatter class, so that you can determine exactly what the output should look like. For instance, I seem to remember an XML formatter, for example. Is there anything like this for System.Diagnostics.Trace? Thanks. Tag: Registering VC# Express Offline?? Tag: 108723

    - How to update the ASPNETDB file (login control) with a GridView (asp.net 2.0) Hello I am beginning to feel sorry that i am using the asp.net 2.0 login controls.. it feels it makes you limited and you do not have much support about it.. I managed to view aspnet_Membership and aspnet_Users into 1 GridView using the SqlDataSource control I can't figure out how to Initialize the built in Update in the GridView so i could update user information from the gridview (including UserName, Password and other stuff i added manually to the database when a user register), or i need to do it manually? I already managed to delete a user with GridView1_RowCommand detecting the button pressed and doing Membership.DeleteUser(row.Cells[3].Text , true); Does anyone can please help me here :\ Tag: Registering VC# Express Offline??

    - deployment of .net 2.0 assembly exposed to COM (interop) Hi, I need to write an application which will then be executed by being called from a COM application. It has been suggested to me that I should use the updater application block, but I wondered about the click once facility in dotnet 2.0. However instead of writing an application, I thought of writing just an assembly which I can expose to the COM application through interop. Now there is just one application to deploy, but it is a COM application. I don't know how the current application is deployed, but is there *any* way I can ease the deployment/maintenance burden of that application by using the click once facility to deploy my assembly, without it being part of a .Net application?

    - Generic Identity and Integrated Security with SQL I have setup the following lines of code: System.AppDomain.CurrentDomain.SetPrincipalPolicy(Security.Principal.PrincipalPolicy.WindowsPrincipal) mPrincipal = System.Threading.Thread.CurrentPrincipal mUser = mPrincipal.Identity ' Create generic identity. mApplicationIdentity = New Security.Principal.GenericIdentity(controlCenterConfiguration.Employee.Alias) ' Create generic principal. mApplicationPrincipal = New Security.Principal.GenericPrincipal(mApplicationIdentity, rolesArray) 'set the thread to run under this new identity System.Threading.Thread.CurrentPrincipal = mApplicationPrincipal I am able to use code-based security using this with no problem. What is not clear to me is how Integrated Security with SQL is still working. My instinct says it should not work, but it does. I would have thought my WindowsIdentity would have been replaced by my GenericIdentity and the thread would not have my windows authentication information. Will someone explain this to me?

    - Cache Dependencies in Winforms?? Hello I have a C# application and am caching some data on the client side by using a HashTable. Is there a way I can set Cache dependencies like a time factor by which my cache is updated by making a call to the webservice, as and when the time expires? I believe on the server side this is done using System.Web.Caching where you have a number of dependencies to set. Is there something similar available for the client side? If not does anyone know how it could be done? I'd really appreciate if you could reply A.S.A.P. Thanks, Vinit Tag: Registering VC# Express Offline?? Tag: 108710

    - Windows Installer 3.1(v2) error When attempting to uninstall Microsoft .NET framework version 1.1, I get these errors: (Application popup, event id 26) Microsoft Visual C++ Runtime Library Runtime Error Program C:\Windows\System32\msiexec.exe This application has requested the runtime to terminate in an unusual way. Please contact the application support team for more information. After a long pause, the second error occurs: The Windows Installer service could not be accessed. This can occur if you are running in safe mode or if the Windows Installer is not correctly installed. I have uninstalled and reinstalled Windows Installer v 3.1 (v2) twice using both methods described in this article: http://support.microsoft.com/default.aspx?scid=kb;EN-US;Q315346 I also tried uninstalling the WI and visiting Windows update where it automatically downloads and installs the installer. None of this has worked. I still get both errors. As I said, this started with trying to uninstall .NET framework1.1. I was following the method to unistall and reinstall, described in this article. (I skipped step 4 that required the Msizap utility included in the windows installer SDK utility) (Did not try the repair method listed here) http://support.microsoft.com/default.aspx?scid=kb;en-us;824643 The reason for uninstalling .NET framework1.1 is that a critical security update (KB886903) will not install. Tried countless times even after sucessfully uninstalling/reinstalling .NET1.1. Have .NET 1.0, 1.1 and 2.0 installed Tag: Registering VC# Express Offline?? Tag: 108706

    - remoting configuration STA I am trying to create a remote object that instantiates an ActiveX control. Apparently ActiveX controls can only be created in STAThreads. When I make the following call from the client: _myRemoteObject = (IRemoteObject) Activator.GetObject( typeof(MyLib.IRemoteObject), host ); I keep getting the following error: {"Could not instantiate ActiveX control 'd5b7f60a-c223-4556-845d-fe5f59e49f03' because the current thread is not in a single-threaded apartment." } I did some searching on the error and people seem to recommend starting threads as STAThreads. But both my server and client were started as STAThread. Something is happening when I make the GetObject() call. When I step into the constructor for my remote object it says that I am in a MTA thread. Does anyone know what I am doing wrong? Is there something that I can put into my remoting configuration file to specify that the remote object should be created in an STAThread? -Corey ----== Posted via Newsfeeds.Com - Unlimited-Unrestricted-Secure Usenet News==---- http://www.newsfeeds.com The #1 Newsgroup Service in the World! 120,000+ Newsgroups ----= East and West-Coast Server Farms - Total Privacy via Encryption =---- Tag: Registering VC# Express Offline??

    - .NET programs memory consumption I noticed that my windows application, very simple test written in C#, keeps and keeps allocating memory. For example, when at the start it has allocated 7500kB, after few minutes, memory allocation is 12000kB. Even if i don't click any buttons or so. And when i start clicking a button, with no event handling, it allocated 40k more memory on every click. Is this normal? Why program needs extra memory after a dummie button click? I'm using .NET 2.0 and Visual C# Express, on WinXP Home with AMD64. Memory figures are taken from task manager. Tag: Registering VC# Express Offline?? Tag: 108696

    - How to find a block in Finalize()? Hello, I'm using .NET Framework 1.1, C#. A couple of days before I've found out that my application leaks memory not releasing objects with destructors. I'm using some third-party components (Spring.NET and Oracle Data Provider .NET (ODP.NET is actually a leak in my case)). I know that it's a good habit to call Dispose() if the object is IDisposable, but in my case I cannot do this, and need to rely on destructor (performance loss was considered). Then I've tried to reproduce the problem in a small test project (with only ODP.NET objects) and failed :(. The leak was away. Now I suspect that Spring.NET/ODP.NET somehow blocks the finalizer thread, so that it never clears the garbage left. Justification: /// <summary> /// Create a new session /// </summary> /// <returns>The new session that can be used by the client.</returns> public ISession CreateSession() { GC.Collect(); GC.WaitForPendingFinalizers(); //Application hangs here GC.Collect(); GC.WaitForPendingFinalizers(); new Message(Message.MessageType.CalledCreateSessionOn0, this.GetType().FullName).LogDebug(); ISession session = (ISession) Application.CreateSession()[typeof(ISession).FullName+".Remote"]; return session; } This method will be called relatively early after the client starts (server and client interact over normal MarshalByRef objects, there is anyway not much interaction there...). It is practically the first client call on the server side. Before the first client starts there will be some Spring.NET initialization done and an OracleConnection opened and closed (to check that the database is available). The problem is that this code hangs on the first call to GC.WaitForPendingFinalizers(). By "hangs" I mean that nothing else will be done in application - no log messages, in Visual Studio I can pause/stop application (shows me a Console.ReadLine(); line - is not relevant). I've been waiting for 15 minutes - no changes. The memory leak was found out by ANTS Profiler and is definitely there. :( I've also installed WinDBG in order to find out where the finalizing thread is blocked, but had not much advance on that field (starting from that I do not know which of threads is finalizing thread). I have source code for Spring.NET, but it is really huge and not quite understandable. I would be happy if I'll find out that the problem is really in Spring. Can anyone help me, please? Do I actually force the garbage collector in a correct manner (Collect/WaitForFinalizers, Collect/WaitForFinalizers)? How can I find out what the finalizing thread is actually doing? Does the observed behaviour (hang on WaitForPendingFinalizers) actually an evidence that there are problems in finalizer? Thank you in advance. Tag: Registering VC# Express Offline?? Tag: 108685

    - Using TcpClient with Modem Hi everybody, I am still learning how sockets, TcpClient and TcpListener work, in order that both sides to send and receive data, both sides must have a socket or TcpListener and a TcpListener right?

Do TcpClient requires a Internet connection to connect say to remote server? So, to connect to a VPN network(remote server), I need to establish internet connection like using RAS. Right?

    - WaitCursor / hourglass in custom printpreview dialog Hi, I have created a simple custom PrintPreviewDialog consisting of a simple standard PrintPreviewControl (.NET 1.1) on a WindowsForm with a few buttons (for printing, zooming, etc.). It is working fine, except for that I cannot figure out how display the waitcursor / hourglass while the preview is preparing to show the document *and then go back to the default cursor when the document is displayed*. Turning on the waitcursor is easy, but what event should I hook into to turn it off?? What happens when I preview a document that is about 50 pages long is that you get the blank form on the screen and then nothing happens for maybe 40 seconds and then you get a "Generating Preview" message and then the document is displayed. It is during the initial 40 seconds that I need an hourglass or something to let the users know that something is happening in the background. Here are some snippets of what I am doing currently: // Constructor: public PreviewDialog(System.Drawing.Printing.PrintDocument printDocument, int zoom) { InitializeComponent(); _printDocument = printDocument; _zoom = zoom; } private void PreviewDialog_Load(object sender, System.EventArgs e) { this.Cursor = Cursors.WaitCursor; Initialize(); //this.Cursor = Cursors.Default; // This gets hit instantly, so you never see an hourglass. } private void Initialize() { uxPrintPreview.Anchor = AnchorStyles.Bottom | AnchorStyles.Top | AnchorStyles.Left | AnchorStyles.Right; uxPrintPreview.Zoom = zoom; this.WindowState = FormWindowState.Maximized; uxPrintPreview.Document = printDocument1 = printDocument; } // The calling code: using (PreviewDialog form = new PreviewDialog(c1Report1.Document)) { form.ShowDialog(this); } If there was an event like LastPageFinished or DocumentRendered or similar in the PrintPreviewControl, I would be home free, but I cannot find anything like that. Any help on this would be greatly appreciated. Thanks, Lars Tag: Registering VC# Express Offline?? Tag: 108648

I have also installed the XMLPrecompiler solution to see if there are any issues with serialization, but everything checks out fin there as well. Lastly, I verified that I was running .NET 1.1.X as some research said that may be an issue as well. I would appreicate any help or any suggestions. -MW ERROR TEXT: at System.Web.Services.Protocols.SoapHttpClientProtocol.ReadResponse(SoapClientMessage message, WebResponse response, Stream responseStream, Boolean asyncCall) at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters) at CUSTOM METHOD DECLARATION System.Web.Services.Protocols.SoapException: Server was unable to process request. --> File or assembly name oaayvpwc.dll, or one of its dependencies, was not found. at System.Web.Services.Protocols.SoapHttpClientProtocol.ReadResponse(SoapClientMessage message, WebResponse response, Stream responseStream, Boolean asyncCall) at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters) CUSTOM METHOD DECLARATION Server was unable to process request. --> File or assembly name oaayvpwc.dll, or one of its dependencies, was not found.

    - Refreshing TreeView after Editing a Label Here's the problem. I have a TreeView that is essentially a listing of directories and files. If you right-click on a directory then a context menu comes up and one of the options is "New Folder", when the user clicks that it expands the current node, creates and add's a child node, then calls BeginEdit() on the child node. I have written a custom class that implements IComparer to sort on rules that I have defined. The problem comes in the fact that BeginEdit() appears to be an async call, and as far as I can tell, there's no event that gets fired to let me know when it is done so that I can then call Sort() on the TreeView. There is an 'AfterLabelEdit' event on the TreeView, but it appears that the actual label on the node isn't changed until after that event is finished firing. I've tried manually setting the text of the node in an event handler for that event, but it causes the TreeView to do wierd things (like the node is still editable after I finished editing it, and if this is the second or so folder I've created, the previous one I create is being reassigned the same name as the one I created. If anyone can help me, I'd appreciate it. Code: ================================================ private void contextMenuFolder_Click(object sender, EventArgs e) { TreeNode newFolder = new TreeNode("", FOLDER_CLOSED, FOLDER_OPEN); tvwReports.SelectedNode.Nodes.Add(newFolder); tvwReports.SelectedNode.Expand(); CatalogItem item = new CatalogItem(); item.Type = ItemTypeEnum.Folder; newFolder.Tag = item; newFolder.BeginEdit(); } private void tvwReports_BeforeLabelEdit(object sender, NodeLabelEditEventArgs e) { if (e.Node.Tag != null) { if ((e.Node.Tag as CatalogItem).Type != ItemTypeEnum.Folder) e.CancelEdit = true; else e.CancelEdit = false; } else e.CancelEdit = true; } private void tvwReports_AfterLabelEdit(object sender, NodeLabelEditEventArgs e) { this.Cursor = Cursors.WaitCursor; string fullPath = e.Node.FullPath.Substring(e.Node.FullPath.IndexOf('/')); if ((e.Node.Tag as CatalogItem).Name == null) { if (e.Label == null || e.Label == "") //this is a new folder and no name was given, delete the node e.Node.Remove(); else { //get path as relative to the webservice fullPath += e.Label; //new folder node, need to call webservice to add CatalogItemManagement.CatalogItemManager.AddFolder(fullPath); e.Node.Tag = CatalogItemManagement.CatalogItemManager.GetCatalogItem(fullPath); } } else if ((e.Node.Tag as CatalogItem).Name != e.Label) { if (e.Label == null || e.Label == "") //the label was left blank, set it back to what it was before e.CancelEdit = true; else { //node already existed, but folder name has changed, need to update CatalogItemManagement.CatalogItemManager.MoveCatalogItem(fullPath, fullPath.Replace(e.Node.Text, e.Label)); } } this.Cursor = Cursors.Default; } ================================================ I am using Visual Studio 2005 (with .NET 2.0, of course) Tag: Registering VC# Express Offline??

    - Nullable<int>, implementing GetHashCode, and thread safety The VS2005 documentation for Object.GetHashCode has three notes to implementors: *blockquote* If two objects of the same type represent the same value, the hash function must return the same constant value for either object. For the best performance, a hash function must generate a random distribution for all input. The hash function must return exactly the same value regardless of any changes that are made to the object. */blockquote* So in a reference type that isn't immutable satisfying the third requirement seems to require caching the hash code the first time it's queried for. This seems like a good place for Nullable<int>. However, if there's a competing requirement for the reference type to be thread-safe, the cached hash code needs to be initially assigned in a thread safe manner. To avoid the thread safety problems with double checked locking, there will be a locking cost associated with initially creating and caching the hash code. To minimize the cost, and since the hash code will be int-sized, it'd be nice to take advantage of the System.Threading.Interlocked class's methods. Hmm, but Interlocked.CompareExchange can't handle the following: Nullable<int> alpha = null; int value = 1; Interlocked.CompareExchange(alpha,value,null); Rats. The nullable type would have seemed cleaner, but boxing an int into an object (below) still works. Is this the best way to go? How bad would the overhead of locking a private instance field and using a nullable type be by comparison? Is there something obvious with Nullable<int> that I'm missing that would support this? Should Interlocked get overrides to handle Nullable<T>? Could such overrides avoid the same overhead that locking a private instance field would face? class Triple<T1, T2, T3> { private Object hashCode; private T1 first; private T2 second; private T3 third; //... public override int GetHashCode(){ if (this.hashCode == null){ int firstHash = (!Object.ReferenceEquals(this.first,null)) ? this.first.GetHashCode() : 0; int secondHash = (!Object.ReferenceEquals(this.second,null)) ? this.second.GetHashCode() : 0; int thirdHash = (!Object.ReferenceEquals(this.third,null)) ? this.third.GetHashCode() : 0; Interlocked.CompareExchange(ref this.hashCode, (Object)(firstHash ^ secondHash ^ thirdHash), null); } return (int) this.hashCode; } //... } Tag: Registering VC# Express Offline??

    - Embed windows media player and possibly others in .net app? I have a list of media files to choose from in the app. Right now clicking on it will launch it using System.Diagnostics.Process.Start to launch whatever appropriate application for that particular file. Since I know the extension of the file, can I embed media player in the app instead of having media player popped up and run separately, just like embedding the media player in the web page with certain functionality show?

    - How to add right click menu Tool: Visual Studio 2005 I have a custom photo library application previously written in VS 6. Basically it has 1) DriveListBox, DirListBox, FileListBox, all listed as Microsof.VisualBasic.Compatibility.xxx 2) PictureBox inside a Panel (for auto showing scroll bars when photo exceeds viewable area). 3) Buttons under FileListBox to Rename, Delete, etc file. I'm thinking there must be something equivalent to Explorer that allows you to single click to rename, right click with a bunch of options (Rename, Delete, Cut, Paste, etc) that I can replace the FileListBox with. If not, then I'd like to make it so that right click on a selected file would prompt a context menu with a few basic options. Thanks. Tag: Registering VC# Express Offline?? Tag: 108608

    - setting envrionment variable in C# and access it within native C++ We are having difficulties getting environment variable within native DLL written in C++ which is loaded by C# .NET assembly, the env var is set by the .NET assembly. We have an existing C++ application, and want to access it within C#. So we wrote Managed C++ wrapper which access the native C++ DLL. The Managed C++ wrapper is compiled as .NET assembly that C# can access. The native C++ DLL need to have an environment variable set to work properly. So within the C#, we use: [DllImport("Kernel32.dll")] public static extern int SetEnvironmentVariable( string name , string value ); to set the env var. But within the native C++ DLL, it will fail when trying to do "getenv()", with error: Object reference not set to an instance of an object. 1. If we make the C# application as console application and set env var in the console before start the C# application, it works. But we can't make the C# app a console app. 2. If we execute within the C# application a .bat file which prints out the env var, it shows that the env var is set. Looks that the native C++ DLL can't getenv() on the env var set within the C# app. Any solutions for this? Thanks a lot. Tag: Registering VC# Express Offline?? Tag: 108605

    - ASP Windows Service or Console based application Hi all, I am confused as to what kind of application to develop. I have to create an application thats like a "Engine" which continously monitors a DB or whatever. It has to work even if the user logoff as this engine feeds some other application. I tried creating a Windows service that runs continously but the status shows "Starting" and i cant "Stop" or "Pause" and was suggested by one BravesCharm that "Status does not change as the service never notifies the SCM that everything started OK" which makes sense. Is there a way for windows service to start some other application? is yes then how can i stop it from this windows service? Please do give me suggestions on how to achieve this.

    - Clickonce install from CD Hi, I generated the deployment files into a local directory with specified installation URL. My prolbems: - If there is an internet connection on the client machine, it skips the files on the local hard drive, immediately start downloading from the web. - if there is no internet connection, the setup.exe fails (which is the startup program from a CD), but the application icon installs the software well. I implemented a custom async update. When I call the CheckUpdateAsync method I have got an exception in the Application.ThreadException event, not in the AsyncCompleted event as the MSDN says (in the e.Error)... Why? Thanks. lelez ------------ Here it is the code: try { ApplicationDeployment dep = ApplicationDeployment.CurrentDeployment; dep.CheckForUpdateCompleted += checkHandler; dep.CheckForUpdateAsync(); } catch (System.Net.WebException) { // never runs! System.Windows.Forms.MessageBox.Show("There is no internet connection."); } catch (Exception ex) { xxxx.Common.Util.Logger.LogException(ex); } Here it is the handler: private static void dep_CheckCompleted(object sender, CheckForUpdateCompletedEventArgs e) { if (e.Error is System.Net.WebException) { System.Windows.Forms.MessageBox.Show("There is no internet connection."); return; } ApplicationDeployment dep = ApplicationDeployment.CurrentDeployment; dep.CheckForUpdateCompleted -= checkHandler; try { if (e.UpdateAvailable) { ContinueQuestionEventArgs ce = new ContinueQuestionEventArgs(e.AvailableVersion.ToString()); // Ask the user about continue... if (updateIsAvailable != null) updateIsAvailable(null, ce); if (ce.Continue) { dep.UpdateCompleted += updateHandler; dep.UpdateAsync(); } } } catch(InvalidOperationException ex) { xxxxx.Common.Util.Logger.LogException(ex); } } // dep_CheckCompleted... -- ----------------------------------- http://www.lelez.hu ICQ: 177465172 Tag: Registering VC# Express Offline??

    - Caching architecture question. I am thinking about using Caching application block in my web application, for the performance reasons. My ideal sitiuation would be if i could plug in the application block between my Persistence layer and database, so that objects are created from the cache and cost of CRUd operation can be avoided.... the problem each object is not having a unique key, and caching application block does not provides any typed cache functionality, for example if i store a product object wtih uid 1 and a customer object with uid 1 then it would overwrite the product object, Iam thinking about creating a multiple cache managers according to the type of object, and keep all those cache managers in a super cache... in that case would the scavenger clean up caches inside a cachemanager object ? any comments Tag: Registering VC# Express Offline??

    - GDI leaks? Hello all, I've just found the issue that really scares me. It seems that ListView doesn't release some GDI objects. Here you are steps to reproduce the problem: 1. Run Task Manager 2. View->Select Columns 3. Check "GDI Objects", press OK 4. Run Visual Studio 2k3 5. Create new Window Forms application 6. Put into the form "ListView" and enter 5 items. 7. Run Application 8. Force application to refresh (e.g. move another window above this application) You will see that GDI objects increase really fast. The same situation with Add/Remove items, GDI objects still increas. I've noticed that I can increase it number even till 10k and after that application starts to glitch. It seems that the problem can be solved after: GC.Colelct(); But this is *really* bad solution which significant impacts to the performance of application. Any ideas?

Anyway, when I read this it is always coming back as a verbatim string literal and the email contains the escape chars (\n). How can I make this a regular string literal so that the email body will recognize the escape characters? Thank you Tag: Registering VC# Express Offline?? Tag: 108590

Hello,

I have downloaded the VC# Express online on a computer,
and by copying the installation files from the temp directory
I installed it on the other one which is offline.

The installation was completed and VC# is running.
However, it pops up nag-balloons and asking me to
register it. Since the computer is cut offline from the web,
the registration is impossible. How to get rid of the
nag-balloons?
