    - proper use of codebase tag I have a .net 2.0 winforms app that references a MS DLL. When I run the app, it fails and says it can't find the DLL. I've turned on Fusion logging and clearly its only looking in the appbase directory. So I added a dependentAssembly section to the app's config file that references the file system location where the DLL resides, as shown: "file://c:/program files/<MsApp>/" Unfortunately, while the Fusion log finds the config instruction, it doesn't seem to be looking in the directory I've specified. Am I missing something? thanks -- Darren Mar-Elia MS-MVP-Windows Server--Group Policy http://www.gpoguy.com -- The Windows Group Policy Information Hub: FAQs, Training Videos, Whitepapers and Utilities for all things Group Policy-related Group Policy Management solutions at http://www.sdmsoftware.com Tag: 3D with .NET Tag: 124646

    - System.OutOfMemoryException Hi! I have the following problem on .net 1.1: I reduced the problem to the following code: byte[] ByteArrayOk=new byte[17000000]; ByteArrayOk=null; byte[] ByteArrayOutOfMem=new byte[16773276]; // Exception here!!! ByteArrayOutOfMem=null; which throws a System.OutOfMemoryException. On .net framework 2.0 everything works fine! But I need a shortterm solution on 1.1!

    - Key repetition Hi group I have a control looking like a TrackBar, a bar, with a cursor. I need when the user push the left arrow of his keyboard, the cursor move left until the key released. I have overloaded the OnKeyDown method like this : protected override void OnKeyDown(KeyEventArgs e) { base.OnKeyDown(e); switch(e.KeyCode) { case Keys.A : this.SelectedBlock--; break; default: break; } } It work very good with the A Key, but the event for left arrow doesn't fire ! only the OnKeyUp is fired by the Left Arrow key. I can't implement the repetition keystroke for arrows, or control, shift .... However, the ListView control for exemple allow me to scroll all the list by push the down arrow, without release it. How to make the repetition of the left arrow key ? Thanks ROM Tag: 3D with .NET Tag: 124644

    - Custom Form working at runtime but cannot be loaded in designer Hi, I have a custom form that works fine when I debug it or run it in release mode but cannot be loaded in the designer... Actually, it can be loaded in the designer when no control is on it, but the resizing tool (in the designer) is offset both horizontally and vertically and when I put a control on it, as soon as I save, the designer throws an exception (but cannot be reproduced everytime) and the form cannot be loaded anymore unless I remove all the controls from it... but the major problem is the offset of the designer... also, I'm unable to move the newly added controls on my form... I can resize them when I add them and after that cannot even select them... this behavior happens when I want to use the custom form (inherit forms of my projects from this form)... When I want to see the form in the designer (the CustomForm itself inherited from system.windows.forms.form) I receive and exception too (here it is) Events cannot be set on the object passed to the event binding service because a site associated with the object could not be located. Hide at System.ComponentModel.Design.EventBindingService.EventPropertyDescriptor.SetValue(Object component, Object value) at System.ComponentModel.Design.Serialization.CodeDomSerializerBase.DeserializeAttachEventStatement(IDesignerSerializationManager manager, CodeAttachEventStatement statement) at System.ComponentModel.Design.Serialization.CodeDomSerializerBase.DeserializeStatement(IDesignerSerializationManager manager, CodeStatement statement) Events cannot be set on the object passed to the event binding service because a site associated with the object could not be located.

    - MS Enterprise Library vs. TransactionManager hello, We are using Microsoft Enterprise Library (http://msdn.microsoft.com/library/?url=/library/en-us/dnpag2/html/EntLib2.asp) The problem is, using this lib causes the connection to use the ms transaction manager when connecting to a sqlserver2000 database (that doesn't happen, when connecting to sqlserver2005) Using the transaction manager is blocked for security reasons, therefore we get this error message: "Der Partner-Transaktions-Manager hat die Unterstützung für Remote-/Netzwerktransaktionen deaktiviert. (Ausnahme von HRESULT: 0x8004D025)" This means something like: "the partner transaction manager has deactivated the support for remote/networktransaction. Exception HRESULT: 0x8004D025)" How can i change the Enterprise Lib, that this lib doesn't use the transaction manager? thanks, dominik Tag: 3D with .NET Tag: 124634

    - System.Runtime.Remoting.RemotingException: Requested Service not found Hi all, I've got this terrible problem. I'm deploying 2 different .NET application (Framework .NET 1.1) that both use remoting technology, but one is a HREF no-touch-deploy smart client and the other one is a .NET control deploy by a tag object. All assemblies are signed with a Strong Name. For the kind of deploy (by IE) and the use of remoting technology I need to configure a Full trust policy because these applications work fine. The problem is that for my security policy when I select the Condition Type Site everything works fine, but when I select the Condition Type Strong Name I've got some trouble. With this condition type the sponsor mechanism don't seem to work properly, infact I obtain the exception System.Runtime.Remoting.RemotingException: Requested Service not found, the same exception I obtain if I don't implement a sponsor mechanism at all. I made test on these platforms: - WinXp + IE 6.0 - WinXp sp1 + IE 6.0 sp1 - WinXp sp2 + IE 6.0 sp2 - WinXp sp2 + IE 6.0 sp2 + Framework .NET 1.1 Service Pack 1 Any ideas ?

    - DataAdapter.Update bug updating Child table via Relations / RowState corrupted? Hi all. .Net 2.0. It seems the DataAdapter.Update Method changes the RowState of child records to 'Modified' when updating them through a Relation. If the child records' .RowState is "Added" or "Deleted," shouldn't they STAY that way? Otherwise when you try to update the child table, you get concurrency errors (record doesn't exist to update) or records fail to delete. Chris B. Tag: 3D with .NET Tag: 124614

    - resource issues after converting from 1.1 to 2.0 I have an ASP.NET Web Application project that I converted to 2.0 from 1.1 and ever since the conversion I have not been able to view any resources in any other language than the default (english). When I set the uiculture in the web config to sv-SE - I still see the english resources. I have a pre-build script in vs.net 2005 that compiles the txt files into .resources files cd C:\Program Files\Microsoft Visual Studio 8\SDK\v2.0\Bin\ resgen.exe "$(ProjectDir)Localization\UsersResources.txt" "$(ProjectDir)Localization\UsersResources.resources" resgen.exe "$(ProjectDir)Localization\UsersResources.sv-SE.txt" "$(ProjectDir)Localization\UsersResources.sv-SE.resources" The satelite assembly for sv-SE is getting created in the \bin\sv-SE\ directory and if I look at it with reflector it has all of the swedish resources in it. So I am confused as to why it cannot retrieve the Swedish resources - has something changed in 2.0/vs.net 2005 that I need to be aware of?

    - updating child records in a DataSet w/ new autoinc values after parent insert? Hi all. Using Dot Net 2.0. I have a typed dataset generated by VS. It contains a parent and a child table with a relationship set up in the MSSQL database and showing in the dataset. _Both_ tables have new records that need to be added to database. I'm able to retrieve the server's autoinc values on the parent table, but I can't seem to get my data adaper to filter the new autoinc values down to the foreign key field in the child table. HOW EXACTLY is this done??? I'm currently doing 3 things: 1. Added an output parameter to the insert command to grab the new autoinc value and feed it into my autoinc field. 2. Set insertCommand.UpdatedRowSource = UpdateRowSource.Both (figure good idea to grab it all). 3. Appended " SELECT @" + identityColumn.ColumnName + " = SCOPE_IDENTITY()" to the insert command. Does #3 keep the entire column's values from being fed back to the DataTable row? Do I need to AcceptChanges? What about if the operation fails and the transaction is rolled back, how do I undo changes made to the dataset? THANKS!!! Chris B. Tag: 3D with .NET Tag: 124606

    - FileSystemWatcher.WaitForChanged surprising (wrong?) behaviour I'm trying to use the System.IO.FileSystemWatcher class in code like... using (FileSystemWatcher changeMonitor = new FileSystemWatcher(".")) { for (; ; ) { WaitForChangedResult c = changeMonitor.WaitForChanged( WatcherChangeTypes.Created, 60 * 1000); Console.WriteLine ("Creation"); } } and the code works as expected unless a file change /other/ than a creation occurs in the folder, at which point the WaitForChanged call no longer returns even after another creation. So, in an empty folder echo >a.txt ("Creation" is printed) echo >b.txt ("Creation" is printed) dele b.txt (nothing happens, as expected) echo >c.txt (** nothing happens ... why? **) Is this the intended behaviour? It seems rather surprising! I note that if I change the code to pass WatcherChangeTypes.All, then the code works as expected, but I get notification of changes I'm not interested in. -- Cheers, John Tag: 3D with .NET Tag: 124602

    - I have problem whis Windows Media Services 9 Series. I have problem whis Windows Media Services 9 Series. I have videostream, which will consist of two streams(512k/bit and 256k/bit).I need to allocate a stream 256k/bit. In SDK is written: Supporting Multiple Bit Rate Files Several versions of the same audio or video content can be stored in separate streams, encoded at different bit rates, in a Windows Media file. When a Windows Media player connects to an origin server, it requests only one each of the possible audio and video streams, based upon the available bandwidth of the connection. However, if a distribution server or cache proxy server connects to download content, it requests all of the multiple bit rate streams. Because the origin server attempts to deliver all of the packets in real time, the download can fail if bandwidth limitations are exceeded. To address this problem, your plug-in can specify a download rate that is slower than real time when it calls the IWMSCacheProxyServer::DownloadContent method. Tag: 3D with .NET Tag: 124590

    - Assembly Minimum Security Requirements Hi, Using VS 2005 Pro., I have built a Class Library (DLL) with several functions, subs, etc... I would like to determine the minimum security requirements. For some reason, the "Security" tab does NOT appear when designing Class Libraries (DLL's), therefore, I cannot use the "Calculate Permissions" button. I tried using PERMCALC.exe, but the resulting .XML file is quite involved and hard to decipher. It has many "demands" nodes throughout and thus extremely time consuming to go through. Is there any way quickly determine .DLL security permission requirements (minimum), or somehow "attach" the XML file generated by PERMCALC.exe to the assembly/DLL in question? There must be an easier way than going through thousands of lines of code trying to find a security "Demand". Regards, Giovanni Tag: 3D with .NET Tag: 124572

    - Changing Route Table from C# I've posted this question in 'microsoft.public.dotnet.framework.compactframework' as well, but despite the great help I still haven't solved the problem. So before going the C++ route I would like to see if anybody in this group may have the answer. What I'm trying to do is change the route table of my Windows Mobile 5 Pocket PC (.Net CF) device (TyTN) using C#. This is probably similar as doing it on standard CF. Using Iphlpapi.dll I can retrieve the route table, but I am unable to change/add a route.

    - access to path ' ' is denied when using createdirectory() I am pretty new to VB.Net, but I am in the process of creating an app that will force a folder to create, along with its subdirectories, when it doesn't exist. Every time I run the following code "Call Directory.CreateDirectory(<path.)" I get "access to the path "<path>" is denied". The folder I am trying to create is on a separate server with access controlled by a domain group. My account is in a domain group with update access. I can create the folder manually. I tried using impersonation functionality, but that doesn't seem to work either. Can anyone give me any assistance?? Thanks!! Tag: 3D with .NET Tag: 124569

    - ClickOnce program fails to run properly after update I am using ClickOnce to distribute a program. It works well except for one detail. When a new version is installed, the program does not initialize properly immediately after the update. The sequence is the user starts the program, is informed a new version is ready, installs it, when it is complete and the main form is displayed, the user needs close the form, and restarts the program to the form to initialize properly. The problem is that several controls are left disabled. The program uses MDI with a main form and several child forms as needed. The problem is on the main form. The controls that are not enabled are two list boxes, a tool bar, and a user control containing a numeric control. The menu and form tool bar initialize ok. The form uses the table layout control and several panelsâ?? controls. The controls that do not initialize properly are in there own panel in a cell of the table layout control. It is like the list boxes are not there, they control the other controls determining when they are enabled. One list box is bound to a table and is filled. However, the value change event does not seam to be working. The other list box, contains a the list of the available MDI child forms and is filled in manually. It list is not filled in or updated even when I generate a new MDI child form. Restarting the program and every thing works normally. How do I get the form to run normally form the start? -- Mike Reed Tag: 3D with .NET Tag: 124568

    - How to speed up reading of large disk files Sorry if this is the wrong news group for this post. I have some large disk files (15-20 MB) that are made up of many records of different types and sizes. I use a BinaryReader to process all the data sequentially (i.e. with many reads operations) and load it into my .NET app. I will have several .NET Apps running on the same computer each of which will need to read these files but never change them. The performance is not awful, but I would like it to be faster. I have looked at Memory File mapping, RAM disks, etc. but I would like to know if someone has a better idea especially if it stays within normal .NET I/O funcationality. Thanks in advance for your help. Valerie Hough Tag: 3D with .NET Tag: 124565

    - How to access a network drive from a Windows service? I have a VB .NET app that lets you create a DTS Package that copies data from an SQL Server to a database located in the specified path (it should work with both local and network drives). You can either run the package from within the application or as a Windows service. If I specify a network drive and run the package from the app, the data is being copied fine, but the service gives me "Table not accessible" error. My understanding is I have to configure my Windows service to run with the proper domain user account. In other words, I need to set my service to log in with an account with the appropriate permissions to the network path I want to access. What's the syntax for that? What functions do I have to use? I could not find any sample code. Thank you for help. Tag: 3D with .NET Tag: 124559

    - Exception handling behaves differently in debug and release versio I have a class library which throws exceptions on errors. I have an exception handler several levels above where the exception is thrown to catch exceptions. When I run the app in the debugger the exception handler is called, however, when running the app outside of the debugger I get the unhandled exception dialog and my exception handler is not called. I am using V2.0 and VS 2005. Does anyone know why this is? Tag: 3D with .NET Tag: 124553

    - Debugger Step Over Attribute Hi, is there an debugger step over attribute that I can use on properties? For instance, I have a singlton class with an "Instance" property: public MyClass Instance { get { if (m_instance == null) { m_instance = new MyClass(); } return m_instance; } } It's annoying when i have a function like, MyClass.Instance.DoSomething(). I have to use the step into command, but first it steps into the property, then i have to go out of that and step in again to go into the actual function. Thanks, Tag: 3D with .NET Tag: 124549

    - DataAdapter.Update PB with a new database Hi, With a NEW database, I have an auto-generate DataSet ()with menu "Add new DataSource...") with two DataTables, parentTable and childTable, and a relation between them. I fill these two tables with five records, then try to update database with these records, using the autogenerate parentDataTableTableAdapter and childTableTableAdapter, after having set a ForeignKeyConstraint on childTable, related to the relation. Some problems appear when I update a new created database. First problem : when I use parentDataTableTableAdapter.Update(), an exception is thrown, telling me that a row ID is already present in parentTable. The problem comes from the autoincrementseed of id column that is set to 0, althrough it is set to 1 in the database. So then first row is updated, its id in DataSet is set to 1, already in table. To avoid this feature, I found two solutions : - Set autoincrement seed to 1. But, a new problem can appear if one record is already in database - Set dataSet.EnforceConstraints to false In this last case, I have a new problem appearing : after the parentTable update, the child table foreign key is set to the last updated row of parentTable. This trouble is certainly due to MSDN advice (ForeignKeyConstraint) : "Constraints are not enforced unless the EnforceConstraints property is set to true" But update works fine when the database has already some records ! So, please, how can I do to avoid all these problems ? Thanks in advance, FG Tag: 3D with .NET Tag: 124538

    - stupid .net framework 3.0 ? Ok guys i know this is a stupid question but here goes. I decided tonight was going to be the night to learn this new .net framework 3.0. I downloaded the new release of .net framework 3. I also installed windows SDK & the visual studio plugins for WF,WCF, WPF. Ok my first quest was try research this LINQ stuff a little bit bit suprised to see nothing relating to the .Net framework 3.0 in visual studio except a .Net framework 3.0 that had stuff like a template for creating XAML app which im not there yet so i don't want to use. Ok one of the first things i was going to see is if "var" was even there and it wasn't. SO i tried to go add System.Query manually through the .Net references and its not there. What gives? What do i need to do so i can start coding stuff with the .Net framework? Id like to do a working example of an windows forms application using LINQ. Any help would be apprecaited. thanks, ncage Tag: 3D with .NET Tag: 124531

    - using preprocessor directive for cross framework compatibility Hello all, I have some common classes that I routinely use with all the dotnet projects that I work with. I have these classes in a separate file so that it becomes easy for me to include them into projects. Some of these projects are done in visual studio 2003 and some are in visual studio 2005. lately I have started using some of the classes (FTPWebrequest) which are specific to the dotnet framework 2.0 (VS 2005). Now this file cannot be included into the vs2003 projects as they would give compile errors. I did not want to to maintain two different files for these 2 environments. I know that we can use preprocessor directives (#if ) for this but I did not know how to identify the IDE version (VS 2003 or VS 2005) to use in the If directive. Can you help me with this. thanks in advance, Praveen Tag: 3D with .NET Tag: 124518
