 - Styles missing after upgrade Today I upgraded from Framework 1.0 to 1.1 and Visual Studio from 7.0 (2002) to 7.1 (2003). Following the upgrade my web site renders HTML with all control style width and height properties missing. Here is a before and after sample of a piece of rendered HTML for a button that has its designer property set to 80px: <input type="submit" name="btnLogin" value="Login" id="btnLogin" style="width:80px;" /> <input type="submit" name="btnLogin" value="Login" id="btnLogin" /> You can see how the style is being omitted, and this behaviour is happening to all controls in all projects on my machine. This weird change in behaviour has totally ruined the appearance of my web site and has killed development stone dead. Does anyone know what's going on? In the meantime I will search KBs, web sites and config options. Thanks Phil Tag: Computers File Structure like Windows Explorer Tag: 51065

 - Problem with UDP socket under NET Framework I have a problem with using UPD under NET framwork. The problem consist if any client disconnect under UDP protocol from server ( code below ) it raise exeption 10054 - It shouldn't be under UDP protocol - becouse this protocol is connectionless and does not have any notification about closing. Exeption 10054 is: An existing connection was forcibly closed by the remote host. Thanks, Volodia. UDP server code (by the way - client done in unmanaged C++) : Sub ThreadProc() _ReceivingSocket = New Socket(AddressFamily.InterNetwork, _ SocketType.Dgram, ProtocolType.Udp) _ReceivingSocket.SetSocketOption(SocketOptionLevel.Socket, _ SocketOptionName.ReuseAddress, 1) Dim listenEndPoint As IPEndPoint = New IPEndPoint(IPAddress.Any, _Port) _ReceivingSocket.Bind(listenEndPoint) Dim state As New StateObject Dim nodecallback As New AsyncCallback(AddressOf RecieveCallback) Dim nodeIP As IPEndPoint = New IPEndPoint(IPAddress.Any, 0) Dim nodeEP As EndPoint = DirectCast(nodeIP, EndPoint) While NodeListenerRun > 0 ReadDone.Reset() Try _ReceivingSocket.BeginReceiveFrom(state.buffer, 0, _ state.BufferSize, SocketFlags.None, nodeEP, nodecallback, state) ReadDone.WaitOne() Catch sex As SocketException If (sex.ErrorCode = 10040) Then state.IncreaseBuffer() Else SwitchSocketOff() End If Catch exp As Exception CloseListening() End Try End While End sub Private Shared Sub RecieveCallback(ByVal ar As IAsyncResult) Try ' ' Get state object ' Dim state As StateObject = CType(ar.AsyncState, StateObject) ' ' Creates a temporary EndPoint to pass to EndReceiveFrom.

 - Unable to debug multiple ASP.NET projects simultaneously Hi, I was trying to debug two different ASP.NET projects at the same time. But I was only able to debug one of them and I got the following error for the other one: "Unable to start debugging on the web server. A debugger is already attached." When I further checked the Output window, I noticed another error message: 'Auto-attach to process '[2248] aspnet_wp.exe' on machine 'CSSVR' failed. Error Code 0x80040001 (Invalid advise flags). Does it mean that I cannot debug 2 different ASP.NET application simultaneously or there is some configuration that I need to do? Any help is greatly appreciated.

 - Non-blocking socket question The following code behaves differently from what I would expect: socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, System.Net.Sockets.ProtocolType.Tcp); socket.Blocking = false; socket.Connect(ipe); isConnected = socket.Poll(30*1000000, SelectMode.SelectWrite); I would have expected that once I set the socket to non-blocking, the connect would return immediately and the poll would wait up to 30 seconds for the connect to succeed. Instead, what I see is that after 10 or so seconds, the Connect() throws a SocketException ("A non-blocking socket operation could not be completed immediately"). Am I misunderstanding the documentation? Help would be appreciated. Joe Tag: Computers File Structure like Windows Explorer Tag: 51015

 - Problems using 2002 Assemblies on 2003 Hi all, I'm creating an addin for the .NET IDE, and have the following problem. It's using C#, and is packaged into a installer with the .NET 2002 version. Obviously, this results in the 7.0 version of Microsoft.VisualStudio.VCProjectEngine.dll being packaged. Now, I need the addin to work with both the 2002 & 2003 version of .NET. For people who have both versions installed (which is my case), there's no problem. But people who only have the 2003 version installed, they get the error message: "The located assembly's manifest definition with name 'Microsoft.VisualStudio.VCProjectEngine' does not match the assembly reference". My question is, what would be the cleanest way to resolve this issue? Will my installer have to dynamically change the manifest, package both 7.0 & 7.1 version of the DLL, or ..? Thanks for any help! Sincerely, Marius Tag: Computers File Structure like Windows Explorer Tag: 50999

 - how to locate & load 3rd party private assemblies at run time? I'm writing an add-on to a 3rd party commercial application. This other app has a bunch of private assemblies -- nothing in the GAC, all private -- and to interact with the app I need to use various objects in these assemblies. That's how this other app's SDK works. The problem is, I don't know in advance where the other app is installed. It has a regular setup wizard so the end user can choose an installation directory. My add-on application is to be distributed via the web, not installed and configured by hand. So I can't assume any particular location for the 3rd party app's DLLs, and I am not going to be around to tweak the .config file for my add-on app by hand each time. It needs to handle things dynamically. Else, I get the dreaded System.IO.FileNotFoundException. I can look in the registry and get the installation path for the 3rd party app, and thus find its DLLs. But what do I do next? I've tried loading these assemblies using Assembly.LoadFrom(), but I'm not sure what to do afterwards -- how do I then create objects, call methods etc? I also read some advice saying I should create a new AppDomainSetup and set the ApplicationBase path to be the path to the 3rd party app, but I'm still not clear what to do after that and then I won't be able to load my own app's private assemblies. Seems like this is a common enough problem and there should be an easy solution, but I can't find it. Can anyone tell me the trick? How do you locate, load and USE private assemblies where you do not know their location in advance but can discover them at run time?

 - DragDropEffects Hi, I'm trying to deal with drag drop technique and get into trouble with DragDropEffect: DragDropEffects.Link and DragDropEffects.Scroll. The explanations of MSDN about them are short and vague: Link - The data from the drag source is linked to the drop target. ScrollScrolling - is about to start or is currently occurring in the drop target. Can anyone give me a more detail comments about such constants ? Any help will be appreciated.

 - Attribute programming Hy, I understand that attribute programming is used to add metadata to the code, but since they are implemented with a class and we can extend that class, we should be able to do any normal class thing with attributes like: -Have methods -Use any kind of code in the constructor and the methods (ex. Use a MessageBox) But the run time will not execute a MessageBox in the constructor?? why? Where is it defiened that and attribute can only have fields (properties) and that the constructor is used only to init these fields....???

 - Drag and Drop in TreeView Hi, I have a TreeView control with hierarchy: A | - B // source | - C D // dest | - E Whenever draging B in to D, Item B is removed and B is added into D node. To implement this task, I ,firstly, write a simple MouseDown event to start a drag-drop action: private void tree_MouseDown(object sender, System.Windows.Forms.MouseEventArgs e) { DragDropEffects dde1=DoDragDrop(s, DragDropEffects.All); } Which such simple methods, I do not expect my task is achieved. I just expected that my tree-view acted normally. But what happend ? When I click (not drag) the item B (or C or D), item B is chosen. But, when I move the mouse (after I click the item) out of the treeview, the selected node in the tree turns back to item A. Is there any mistakes ? Can any one help me to make the tree view acting normally ? Thank in advanced. Tag: Computers File Structure like Windows Explorer Tag: 50941

 - Starting a new thread in ASP.NET application Hello, Some pages in ASP.NET application perform very process-intensive tasks (parsing large flat files, saving data to SQL Server, etc.. ) Some tasks might take longer to execute than users' expectations. New thread(s) will be started for these process-intensive tasks, so asp.net process can take over and send response to the client's browsers. Does anyone see any issues with this scenario? How can application inform user when thread is completed or failed after response was sent to a browser. Can some kind of client-side object maintain connection with the server and inform a user of the progress and when thread is completed/failed. Any other alternatives? Thank you in advance.

 - Overriding ProcessKeyPreview, Enter WM_KEYDOWN... Hi, I have 3 questions regarding the code below: 1) Why can't I trap the KEYDOWN while I can trap KEYUP? 2) Is it correct that I use Return True within the IF-Statement? (I've already read the documentation but it is rather hard to understand so please don't refer to it :) 3) Many examples in the newsgroups use Return MyBase.ProcessKeyPreview(m) as the last code line while I have used Return MyBase.ProcessKeyEventArgs(m) according to the MSDN, is this correct or is it a typo in MSDN? (watch for line breaks in the url) ms-help://MS.VSCC/MS.MSDNVS/cpref/html/frlrfsystemwindowsformscontrolclasspr ocesskeypreviewtopic.htm I aslo wonder if my code is correct as to subtitude Enter key with Tab in a specifik column of the a datagrid.

 - SerializationException I have created an add-in for VS.NET and when it starts I want the add-in to read the options from file. I have created a class (with the [Serializable] attribute set) that contains the options and implemented GetObjectData(SerializationInfo info, StreamingContext context) as well as a copy constructor: protected Options(SerializationInfo info, StreamingContext context). The serialization process definately works. However, on startup I try to create an instance of my Options class and deserialize the file, but I get a SerializationException as follows: Engine.LoadOptions: System.Runtime.Serialization.SerializationException: Cannot find the assembly CodeStore, Version=2.0.0.0, Culture=neutral, PublicKeyToken=null. at System.Runtime.Serialization.Formatters.Binary.BinaryAssemblyInfo.GetAssembl y() at System.Runtime.Serialization.Formatters.Binary.ObjectReader.GetType(BinaryAs semblyInfo assemblyInfo, String name) at System.Runtime.Serialization.Formatters.Binary.ObjectMap..ctor(String objectName, String[] memberNames, BinaryTypeEnum[] binaryTypeEnumA, Object[] typeInformationA, Int32[] memberAssemIds, ObjectReader objectReader, Int32 objectId, BinaryAssemblyInfo assemblyInfo, SizedArray assemIdToAssemblyTable) at System.Runtime.Serialization.Formatters.Binary.ObjectMap.Create(String name, String[] memberNames, BinaryTypeEnum[] binaryTypeEnumA, Object[] typeInformationA, Int32[] memberAssemIds, ObjectReader objectReader, Int32 objectId, BinaryAssemblyInfo assemblyInfo, SizedArray assemIdToAssemblyTable) at System.Runtime.Serialization.Formatters.Binary.__BinaryParser.ReadObjectWith MapTyped(BinaryObjectWithMapTyped record) at System.Runtime.Serialization.Formatters.Binary.__BinaryParser.ReadObjectWith MapTyped(BinaryHeaderEnum binaryHeaderEnum) at System.Runtime.Serialization.Formatters.Binary.__BinaryParser.Run() at System.Runtime.Serialization.Formatters.Binary.ObjectReader.Deserialize(Head erHandler handler, __BinaryParser serParser, Boolean fCheck, IMethodCallMessage methodCallMessage) at System.Runtime.Serialization.Formatters.Binary.BinaryFormatter.Deserialize(S tream serializationStream, HeaderHandler handler, Boolean fCheck, IMethodCallMessage methodCallMessage) at System.Runtime.Serialization.Formatters.Binary.BinaryFormatter.Deserialize(S tream serializationStream) at Salamander.Addins.CodeStore.Engine.Engine.LoadOptions() in c:\development\codestore\engine\engine.cs:line 78 Why can't it find the assembly?

 - Remote Development of VB.NET Application Dear all, Can you please provide some information on the following issue, at the earliest. I have a development server setup in the network, say machine X. Also, there is another workstation, say Y, for a programmer, to work with. The application is a Winforms Application and machine X (server) does not have Visual Studio .NET installed on it. Machine Y(workstation) has got Visual Studio .NET installed on it. Y is connected via sourcesafe to the solution in X, without making a local copy( I mean through a network share). There are issues faced by the programmer, in executing the application in X, via Studio environment in Y. Basically application is not doing any database related activities, and throws exceptions and breaks at will. Will this kind of a scenario ever work??? If not, please detail a suitable alternative. Two constraints are a> No direct access to the Server X is possible for development. b> Things need to be stage managed from the workstation Y. Please respond at the earliest. Regards..

 - Return string from Fortran Dll back to C#. Dear all: My C# program need a string returned from a Fortran Dll. The Fortran Dll is like this: SUBROUTINE REDO(s) !DEC$ ATTRIBUTES DLLEXPORT::REDO, C CHARACTER*(*) s !DEC$ ATTRIBUTES REFERENCE :: s s = 'Let them talk, now!'C END And I use C# PInvoke to call it, the client code like this: public class BackString { [DllImport(@"BackString.dll", EntryPoint="REDO")] public static extern void REDO(string output); } string output = ""; BackString.REDO(output); When I call this, I got an NullReferenceException, can anybody here explain why? and how could I return the string? I also tried to return the value as "Return" but have the same problem. The .NET Framework's PInvoke example to use C's return string works fine, but I just can't make the Fortran work. Thank everybody and hope I could get some reply. Regards Alex Tag: Computers File Structure like Windows Explorer Tag: 50776

 - Should I close a connection in a dispose method? I've built a class to broker the data in may application. In other words, when my business logic needs a list of widgets in the db, it calls mybrokerclass.getWidgetList, which might return a collection or arraylist of widgets. This way, the business logic doesn't care about where the data comes from. (BTW, this is a web application) So my problem is this.. during a postback, a series of operations will occur wherein perhaps three requests to this broker class will take place, all for different sets of data. Rather than opening and closing the connection to the db in each method (three times opened, three times closed in this case), I think it would be better to OPEN the connection in the constructor of the class and then put the CLOSE method in the destructor (dispose). Does this sound like correct thinking or am I screwed up in how I'm approaching this? P.S., since I'm only worried about closing the db connection in this dispose method, I'm assuming I should _not_ call the GC.suppressFinalize method so the GC can clean up anything remaining...? Thanks for any help on this!! Tag: Computers File Structure like Windows Explorer Tag: 50766

 - Security: securityexception with web parts (SPSv2) Hi All This is one for the experts! I have developed a Web Part (in C#) which should list some entities from Active Directory using System.DirectoryServices, all compile fine - but when trying to execute the Web Part on a Web Part Page I keep getting a "system.security.securityexception". All comes down to the call: DirectoryEntry d = new DirectoryEntry(ldapPath); where ldapPath is any valid LDAP path towards our directory in the format "LDAP://dc=domain,dc=com/cn=users,dc=domain,dc=com" or something similar... I have written tons of code using ADSI and COM and a quick vbs-script to prove I'm hitting the right ldap-objects also evaluates to true. However this DirectoryEntry call destoyes the Web Part page and breaks with the securityexception error. I guess it has something to do with the security levels in the .Net framework, but I don't know where to look. I have tried to assign full trust security to my assembly using the .net 1.1 wizard with no success. Any inputs anyone...?

 - Passing objects between AppDomains Hi all, I need to extract type information from an assembly and unload the assembly to prevent it from locking. So I create separate application domain, explore the assembly via Reflection in this domain (this results in building a hierarchical data structure containing the information about the types in the assembly) , and unload the domain. The question is what is the best way to pass the data structure from this domain to the default domain where the main work happens? Should I use BinaryFormatter and write a file or there are better methods? Thanks in advance. Dmitry Shaporenkov Tag: Computers File Structure like Windows Explorer Tag: 50599

 - Raise event from library worker thread. Hi! I am writing a library in managed C++ for the .NET framework. I have problems fireing events from a worker thread. The managed event must be raised from the main thread, but I cannot find any way to pass control from the worker thread to the main thread. In the COM programming model the problem was solved by creating an invisible window which the worker thread passed win32 messages to. With what is that paradigm replaced in .NET? I have found some solutions that involves the Control.Invoke method. This approach works if you got access to the clients Form handle, but since I am writing a library (and not a control) I don't now how to get that. Instead I get this error message if a I let my class inherit from Control and then call Invoke() "An unhandled exception of type 'System.InvalidOperationException' occurred in system.windows.forms.dll Additional information: Cannot call Invoke or InvokeAsync on a control until the window handle has been created." Do anyone have the solution of how to raise events from a .NET library's worker thread? I would be more than pleased if I anyone gave me some key information!

 - Trust an assembly (not using.net wizards?) Hello all, first of all I'm just a simple system administrator and I have no idea how Framework works - that's why I need your help. Our devoloper team is just in the process of writing a couple of new programs for internal use. They're using C# and their programs require the latest Framework version on every client PC. Using group policies I installed Framework on the clients - no problem there. But what I have a problem with - and where I'd need your help - is when it comes to trusting those applications. Now I have two questions: 1. According to my colleagues you can't write a Framework-based program without security. So everytime you have a new application or change an application you have use the "Trust an assembly"-Wizard on every workstation again. Is that right? 2. If 1.) is right, do you have any idea on how to do that process automatically ... using i.e. group policies and other means. I don't want to run around every couple of days (that's about how often our developers change their programs) to change the trust on about 100 PCs. I couldn't find any info on that on the web. I'm sure it's out there somewhere - but as I have no idea on how the whole .NET and framework things work I hit a wall when it came to understanding the articles. So I gave up my quest for knowledge on the web and kindly ask you to lend me a hand. I'd really appreciate any hint you could give me! Thanks, Christian.

 - Unloading assemblies Hi all, I'm developing a tool that explores contents of assemblies via reflection. When the tool is requested to get some information from an assembly, it loads the assembly and reads the information. I would like unload the assembly immediately after to prevent it from locking and give the client a possibility to update it. Is there any way to do this? System.Assembly class has no Unload method, so I create separate application domain and load the assembly in this domain. Then I unload the entire domain by AppDomain.Unload call. However it seems that the loaded assemblies are still locked even after unloading the domain. Has anybody ideas about the reasons of such behavior? Or can anyone suggest other ways to solve the problem? Thanks, Dmitry Shaporenkov Tag: Computers File Structure like Windows Explorer Tag: 50496

 - IIS not retrieving latest version of assembly from GAC I was working on one of my assemblies yesterday which we have in our GAC and is used by a number of our web applications/sites on our intranet. Something strange started happening though. I would compile the program, then do the following in order given: gacutil /u myAssembly gacutil /i myAssembly.dll net stop iisadmin net start w3svc Yet IIS and the web applications conitnued to use the old code, no matter how i played with these steps and the order of them. The only way i could get IIS to use the new code was to open a windows explorer windows to C:\WINNT\Assembly, locate my assembly, right click it and go to properties. Once i did this, IIS would use the new code. This sounds totally bizarre, but i ran the process over and over and over and over, first trying without going to the file, then going to the file, and it was 100% consistent. Can anyone explain this behaviour to me?? TIA - Aaron. Tag: Computers File Structure like Windows Explorer Tag: 50221

 - Debugging Shared Assemblies (ex. Custom Controls) Hi Gurus .. I would really appreciate some insights for the problem that bugs me for quite some time. I keep my custom controls in their own shared (private/public key signed) assembly. I need to have it shared. Usually I work with a Web application project that has a reference to my shared, custom controls assembly. Web project is a "Startup Project". I need to be able to set a breakpoint in my Custom Controls (shared) project. VS.NET solution can hold more then one project - that's the most convenient way to go. There is no problem to stop debugger at that breakpoint having all assemblies kept as private. Annoyance begins with shared assemblies and its projects not being set as a startup project. The reference "Copy Local = false" always locks them up producing errors : "The file xxx cannot be copied to the run directory. The process cannot access the file because it is being used by another process". "Copy Local = true" helps to eliminate the error since the reference is no longer kept by public key in my Web application's manifest BUT even though they should be treated at this point as private assemblies I can't seem to get them to debug at all. I keep my shared assemblies in GAC so the reference with "Copy Local = False" at the run time concerns this location. Sometimes I succeed and can debug inside my shared assembly from other startup project but in so indeterministic way. No matter what - locking up shared assembly at the compilation time undermines efficient way of working with multiproject VS.NET solution. Can somebody share any guildlines, experiences ?

Hi

I would like to display all the files and folders , drives in tyhe system in
