    - separating Machine.config into Named Assemblies' configs I have a suggestion for the Framework guys: It would be nice to have a "default config" similar to Machine.config that can more easily be deployed than merging my "default.config" with the machine's machine.config For instance, I'd like to add some deafult settings for my class library... only way to do that is to either embed my default settings in the machine.config or somehow encourage the users of the library to merge my config into theirs... not very graceful... I suggest moving to a more broken up format, whereas each Assembly's FullName gets a config file: System.Web, Version=1.1.4322, PublicKeyToken=XXXXXXXX.config System.Web.Services, Version=1.1.4322, PublicKeyToken=XXXXXXX.config and so forth, then I can do mine without merging: Ensoft.DataComponents, Version=1.0.1000, PublicKeyToken=XXXXXXX.config i still like the machine.config idea, but its become just like the registry... one big area that could easily become corrupt through just one bad character. Anyhow, thats my suggestion... maybe we'll see it in Framework 2.0?

    - Config file. How can I add a config file to a windows forms project in Visual Strudio.NET. (for example, I have Application.exe project and I want to add new item (config file), Application.exe.config, to the project). It doesn't seem like there is a way to do so. I can do it by hand but I would also have to remember to put this file into the ..\bin\debug directory. Tag: upgradation Tag: 63032

    - Hide forms from taskbar in Windows CE.NET v4.1 Hello! I'm using .net Compact Framework to write an application for Windows CE device. I know that .NET CF does not support MDI applications, only SDI. So, my problem is: when a new form is openned, it blocks the parent window, shows itself on the screen and in the PDA's taskbar, that is not good, because the user can navigate through the blocked parent windows (they redraw on demand, but do not respond the the events), and then he can be lost. Ok, I decided to hide parent windows before shoing the child one; but after destroying the child, the parent stays minimized and a user must click on taskbar app icon to bring the form on the PDA's screen. I would like to find a solution how to hide parent winows and make them restore their state after showing child dialog form. Is there any solusion? I tried to search on MSDN and inet, but no results... :( I use .NET CF 1.1, Windows CE. NET v4.1. Thank you! Alex Tag: upgradation Tag: 63026

    - multi project solution > have to BUILD whole solution to see changes in a single project (DLL) I have this 58 project solution I maintained for 6 months now after taking over. Usually the advantage of having it broken down in many projects was, that i could just edit a single .cs file, than compile the project it is in. this would generate the appropriate DLL and i could just "reload" the current page of the application I was on, and see the changes take effect. Now after installing the app on a new machine, I noticed that after i make changes to a file in project, and build that project, and step through it with debugger, it does not see the changes and attempts to step on the lines as they were before my change. Until i run a BUILD on whole solution. i am suspecting that this might have something to do with my project refrences. Not exactly sure yet. TIA. Tag: upgradation Tag: 63017

    - Printer Synchronization HI, I need to perform Synchronization of Requests to Printer. As the printing application is deployed on many App Servers. I would like to gain exclusive access or rather queue my requests serially. The Requirement: One Application Print job involves printing of multiple Word documents which involves opening them in Word automation objetc & then firing Printout for the same sequentially. The Fear: Because of Multiple App Servers performing similar tasks, i would like one print job(having multiple print requests) to be executed sequentially for each App Server. so that the printout doesnt come mixed up. you can think of a catalogue of items being printed, while the contents of the catalogue are different Word Documents & each catalogue request can comprise of many such print requests. As each App server can fire printing of the catalogue (composed of many different Word documents), i would like that the target printer should print out only one catalogue request at a time (i.e from one app server) while the next gets a chance when the first one is done) so that the print outs of the catalogues aren't mixed up.. Something like a Semaphore implementation is needed, currently i'm working on workarounds. Is there any proper way to accomplish this , using APIs, etc ??? I'm developing this component in VB.NET Kindly advise... Thanks in advance, Vijay Kumar Tag: upgradation Tag: 62996

    - 1.1 Framework Upgrade Issues... I have just upgraded from VS.NET 2002/Framework 1.0 to VS.NET 2003/Framework 1.1 and migrated my current web dev project to VS.NET 2003/Framework 1.1 as well. On my local machine, this all seems to have gone well. However, after refreshing this same project on the ISP server that hosts my "production" version of said project, I am getting all sorts of bizarre errors. I am assuming this may due to the fact that my ISP is still running .NET Framework Version:1.0.3705.288 and my local version is 1.1. Anybody shed any light on this or point me to a place on Microsoft that has specific articles that might help me figure this out. Thanks, Tim Heffernan Tag: upgradation Tag: 62987

    - XmlDocument read from Network Stream I have been using the following code (successfully) to read Xml formated text packets from a TCP stream. The output from the server stream consists of a sequence of well formed Xml documents written to the output stream. We are willing to pay $ to any expert (e.g. MVP) consultant who has to time to help us track down this problem. (we will discuss rates if you can prove your expertise, and problem solving approach). The code below is for the client that is reading the stream. All this worked well, as long as long delays were between each "packet". But when multiple packets are sent in quick succession, it is dropping packets. I have been trying to do this more "correctly" with using a XmlTextReader, but with no luck. E.g. XmlTextReader r = new XmlTextReader(); reader.MoveToContent(); string s = reader.ReadOuterXml(); dgram.Load(s); It basically hangs on the ReadOuterXml(); Here is the original "working" code: -------------------------------------------- private void OrchTalk() { int bytesRead = 0; XmlDocument dgram = new XmlDocument(); while (true) { byte[] buffer = new byte[1024]; // buffer for socket read stream bytesRead = 0; try { bytesRead = oStream.Read(buffer, 0, buffer.Length); } catch (Exception e) { if (stateCode == Common.stateCodes.shutdown) {break;} Tools.Debug(10, "OrchTalk: read error {0} ", e.ToString()); break; } if (bytesRead == 0) { if (this.stateCode == Common.stateCodes.shutdown) { Tools.Debug(10, "OrchTalk: Orchestrator died"); this.Disconnect(); return; } break; } else { string s = Tools.ByteToStr(buffer, 0); try { dgram.LoadXml(s); } catch (Exception e) { Tools.Debug(0, "OnReadComplete: {0} Runt packet: {1}", e.ToString(), s); } int endTime = Environment.TickCount; this.inPacket = dgram.DocumentElement; Tools.Debug(10, "packet: {0}", inPacket.OuterXml); this.Dispatch(); int startTime = (int)this.stats["start"]; int elapsed = endTime - startTime; this.stats["stop"] = endTime; this.stats["time"] = elapsed; this.stats["bytes"] = bytesRead; this.stats["packetText"] = inPacket.OuterXml; if (StationMaster.isConnected) { string outPacket = inPacket.OuterXml; FlashComm.itself.Send(outPacket); } } } this.Disconnect(); } Tag: upgradation Tag: 62952

    - race conditions caused by Thread.Abort I have been looking for ways to prevent asynchronous Thread.Abort calls from wreaking havoc in my code. I'm working on an assembly, implemented in Managed Extensions for C++, that makes unmanaged calls and often needs to free resources associated with those calls: bool allocated = false; try { ... // Allocate some resources in unmanaged code allocated = AllocateUnmanagedResources(); ... } __finally { // Only free resources if allocation was successful if (allocated) FreeUnmanagedResources(); } This code should work fine if the thread running it is not aborted. However, asynchronously aborting the thread can lead to two problems: - The ThreadAbortException can be thrown from inside the __finally block, causing the resources to be leaked. This possibility is noted in the Thread.Abort documentation. - The ThreadAbortException can be thrown after a successful call to AllocateUnmanagedResources but before the assignment to the boolean variable. In that case, the code in the __finally block isn't aware of the current state, so the resources are leaked. Both of these scenarios seem to be the result of deficiencies in the .NET Framework and/or CLR: 1) __finally blocks aren't guaranteed to run to completion 2) There doesn't seem to be a way to create an "unabortable" block of code. Obviously, this kind of feature could be abused (and would preclude the need for (1) above), but it seems necessary in order to allow clean- up code to know the state of the application. Anyway, I'm looking for ways to eliminate the race conditions described above. So far, the only solution I've found is to surround the whole block with a try/catch, and push the state variable assignment into unmanaged code (which can't be aborted): #pragma unmanaged // Error-checking ignored for clarity void AllocationWrapper(bool* pAllocated) { *pAllocated = AllocateUnmanagedResources(); } void DeallocationWrapper(bool* pAllocated) { if (*pAllocated) { FreeUnmanagedResources(); *pAllocated = false; } } #pragma managed bool allocated = false; try { try { ... AllocationWrapper(&allocated); ... } __finally { DeallocationWrapper(&allocated); } } catch (ThreadAbortException*) { DeallocationWrapper(&allocated); } Can anyone think of a cleaner way to remove the race conditions? Something in the language or framework I've missed? A configuration setting that magically disables Thread.Abort? Thanks... Tag: upgradation Tag: 62950

    - RunDll or remote activation needed In the .NET Framework Developer's Guide there is a page titled Building a Host application. Within this page there is a note: Unlike COM, remoting does not start the host or server application for you. This is an important difference between .NET remoting and remote activation in COM. I need this functionality. I need to be able to start a seperate win32 process and communicate with it. The trick is that there must not be any need for configuration files or such. I could approach the problem one of two ways. Either my client dll can reference the server exe (but referencing an exe is not allowed by the IDE). Or I can reference and execute a dll. The reason I want to reference it is to make sure that VS always puts a copy of it where I can find it, so I can execute it. Another possibility is to make the server app also a COM server and just register it that way, but this is not managed and VS will not register an exe this way. Tag: upgradation Tag: 62948

    - Accessing Form Controls From Threaded Delegate via Async Callbacks. I have a Form that hosts a control (used for visual feedback). From this form a Class is created. This Class has several events/delegates that are triggered by a Socket (which is a member of the class)'s Async Callbacks. [Eg OnConnected, etc ]. From within this delegate eg. OnConnected, OnReceivedData and OnClose I need a way to be able to provide visual feedback to the form. I setup an event/delegate on the Form and made it public so others could access it. A refernece to the Form was passed to the Class when it was created. However the minute i call Parent.Invoke (Parent.VisualMethod,......) the program hangs. Trapped inside a Try catch to catch any exceptions the program just hangs. I've stepped through the code and when I step into that line the program and debugger never come back. I've tried Control.Invoke, new DelegateMethod(parameters), Parent.VisualControl.Methodstoupdate Maybe there is something here I dont quite fully understand. Maybe there is something very simple that I'm missing. Or Maybe there is an alternate method of achieving my goal. Tag: upgradation Tag: 62947

    - working with TCP/IP I have a client server application where the client sends mouse movements and text to the server like "MVU 15" would move the mouse up 15 pixels and "CHAR a" would send an 'a' to the current application. The problem I am having is that when I try to send a string of chars I get multiple sends when I read from the TCP/IP stream for instance on one read I might get "CHAR aCH" then the next read I will get "AR bCH" which obviously breaks my code. I am using the following code to send the data --------------------------- System.IO.StreamWriter NStream; client = new System.Net.Sockets.TcpClient(); client.Connect(System.Net.IPAddress.Parse(strIPAddress),6254); NStream = new System.IO.StreamWriter(client.GetStream()); NStream.Write(s); NStream.Flush(); --------------------------- and the following to read the data --------------------------- skt = listener.AcceptSocket(); byte[] b = new byte[15]; res = skt.Receive(b); ---------------------------------------- I was thinking i will pad the data to 15 chars but it doesn't seem to be a problem for most things, but that might have been a result of the speed it was sent. Any ideas would be great. Thanks in advance, ~Logan Tag: upgradation Tag: 62943

    - pwdLastSet and other Active Directory Date types Has anyone been able to get the "date" properties (pwdLastSet, lastLogon, etc.) from Active Directory using JUST the native .Net tools (no com interop with activeds)? When I try to do that, I get strange results. Consider the following simple code: (for this a .Net reference is set to System.DirectoryServices) Private Function Test(ByVal sLDAPPath As String) Dim de As New DirectoryEntry(sLDAPPath) Dim sr As SearchResult Dim ds As New DirectorySearcher(de) Dim lTemp As Long ds.PropertiesToLoad.Add("pwdLastSet") ds.PropertiesToLoad.Add("lastLogon") sr = ds.FindOne If sr Is Nothing Then 'not found Else lTemp = sr.Properties.Item("pwdLastSet")(0) End If End Function With MY user ID, lTemp ends up with 127133852422713849. That's fine, I can use a DateTime.FromFileTime, but it comes back with a date that is about a day off from what I get back using the interop (not just the UTC time difference). I get similar results on other accounts (sometimes it is very close, other times it is WAY off. When I use the Microsoft sample "Active Directory Browser" (adsvw.exe) it shows this value should be 127133856717681145. Again, similar results on other accounts. Samples: above code adsvw.exe 127129877390570772 126626200214730160 126625284477162600 126625284477162600 (yes, this one comes out the SAME!!!) I know I can use something like this: Private Sub Test(ByVal sLDAPPath As String) Dim objUser As ActiveDs.IADsUser objUser = GetObject(sLDAPPath) Dim dt As Date = objUser.PasswordLastChanged() End Sub And it will work (as long as I referenced ActiveDS), but I do not really want to ship the Interop.ActiveDS.dll along (or use COM) for this.

The Value field should contain integers as each of them are autonumbered by the database. The code I am using to populate the dropdownlist follows. Any help would be greatly appreciated. Dim connString As String = "server=192.168.25.245;uid=sa;pwd=nuts@sigcom!-1;Initial Catalog=SIGCOMproposal" Dim conn As SqlConnection = New SqlConnection(connString) Dim sql As String = "SELECT * FROM tblContractVehicle ORDER BY ContractVehicle" Dim da As SqlDataAdapter = New SqlDataAdapter(sql, conn) Dim ds As DataSet = New DataSet() da.Fill(ds, "tblContractVehicle") Dim dt As DataTable dt = ds.Tables(0) dt.DefaultView.Sort = "ContractVehicle" Me.ddCVID.DataSource = dt.DefaultView Me.ddCVID.DataTextField = "ContractVehicle" Me.ddCVID.DataValueField = "CVID" Me.ddCVID.DataBind() Me.ddCVID.Items.Insert(0, "--Select a Contract Vehicle--") Me.ddCVID.Items(0).Value = "0" conn.Close() Tag: upgradation Tag: 62932

    - Clearing the download cache on client machines Is there an elegant way to clear the download cache on a client machine? We are deploying a winforms browser and smart client application. Recently we made a mistake with versioning (we release a version with a very large number), and now our internal clients can't download a newer version. Since this is still in house we can install gacutil on people's machines and get it to clear the cache. But this got me thinking, what could we do if this happened with an internet deployed version of application? How does a normal end-user clear their download cache? We can't ask an end-user to install a utility, that would violate the entire purpose of creating a smart-client that runs at the internet trust level. We clearly can't get people to install gacutil. Any idea what to do? Mark Levison "in smart client deployment heck" Tag: upgradation Tag: 62929

    - Getting a list of Roles a user belongs to using Windows Security Principal Hi I have created a windows application in .NET using C# here is the Code Snipp public static void Main() { ... // Tell the CLR to use Windows security AppDomain.CurrentDomain.SetPrincipalPolicy( PrincipalPolicy.WindowsPrincipal); // Get the current principal object WindowsPrincipal prin = (WindowsPrincipal) Thread.CurrentPrincipal; // Determine whether the user is an admin Boolean fAdmin = prin.IsInRole(WindowsBuiltInRole.Administrator); Console.WriteLine("Administrator:" + fAdmin); } As you can see I can determine if the current user belongs to Adminstartor, but is there a method where I can get the list of Roles that a particualr use belongs to. Moreover what is the String equivalent of WindowsBuiltInRole.Administrator so that I can use that string in the method WindowsPrincipal.IsInRole(String); voeivk Tag: upgradation Tag: 62927

    - Asynchronous socket problem w/datagrid Hi All -- I am new to VB.Net so bear with me. I have an application where I need to connect to a remote tcp port synchronously, and then asynchronously wait for a data stream to come from the connection. As data comes in, I want to parse it and add it to a DataSet, to be displayed in a Windows Form Datagrid. To test the idea without fooling with the dataset/datagrid, I wrote my raw asynchronous response to a TextBox using a Receive/ReceiveCallback function pair, as per the MS examples. This works fine with no UI problems. Now that I have added the DataGrid into the mix, any time I do anything (click, scroll, select a cell, resize column) to the UI of the datagrid, it seems like the IO is blocking and the application freezes until some data gets passed and/or the MS Gods are satisfied. I'm not sure what's going on. If I turn off the I/O, the datagrid acts fine. If I don't try to populate the datagrid from my ReceiveCallback function, but rather with static data on Form_Load, that works fine too. When I combine the datagrid with the updates from ReceiveCallback, it gets stuck. Any help appreciated. Thanks, Dave Tag: upgradation Tag: 62925

    - Interacting with a service? Hey, I'm trying to build a component that satisfies the following properties: 1) only one component is ever created and it maintains its state 2) it can be accessed by any thread on the local machine simultaneously (I will do the synchronization myself since I want read/write locks) 3) the component is never deleted 4) I need to call some of its methods It seems like component services are the way to go (or maybe Windows services?) but I can't figure out how to keep the component alive without using JITA. And if I use JITA, synchronization is done for me. And if I use a Windows service, I don't seem to be able to call methods on it. Any suggestions of resources or ideas I can investigate? Thanks in advance. Tag: upgradation Tag: 62921

    - ISerializable and SerializableAttribute confusion Hi ! This question was discussed once, but the subject is still unclear: According to Jeffrey Richter article (http://msdn.microsoft.com/msdnmag/issues/02/04/net/default.aspx) one can't serialize the type without declaring it with SerializableAttribute. At the same time, we have to impalement ISerializable if we need some custom serialization. In addition, we find the following in MSDN: "Apply the SerializableAttribute attribute even if the class also implements the ISerializable interface to control the serialization process." (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfSystemSerializableAttributeClassTopic.asp). From all this it can be concluded that ISerializable and SerializableAttribute are not intended to be used one instead of other, but in addition (if needed). However, in Marshal-By-Value Objects section (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpguide/html/cpconremotableobjects.asp) I find the following: "Marshal-by-value (MBV) objects declare their serialization rules (either by implementing ISerializable to implement their own serialization, or by being decorated with SerializableAttribute, which tells the system to serialize the object automatically)" The "or" there at the middle confuses me... Thanks for clarification. Jean Tag: upgradation Tag: 62913

    - Using The Equivalent Of 'On Error Resume Next' In A Try/Catch Hi All. I have a try catch block which may encouter an error with an empty field: ***** Code Start ***** Try txtPartNumber.Text = Datarow.Item("PartNumber") txtPartDescription.Text = Datarow.Item("PartDescription") txtPartNumber.Text = Datarow.Item("PartNumber") Catch ex as system.exception End Try ***** Code End ***** I would like to use something like the old on error resume next, which would ignore the error and continue with the next line of code. How would i do this in this example? One way is to enclose each statement in a try catch itself, but this makes the code look terrible, whereby it was easy enought pre-,net with the on error resume next.

    - Asynchronous calls Hi all, Is there a way to cancel an asynchronous call? For example, using the Socket class, if you call BeginReceive, can you cancel the call if some timeout has expired? Thank you in advance for your help Tag: upgradation Tag: 62893

    - Reference problems & custom controls disappearing Hi all, I really hope someone out there can help me as I've been tearing my hair out on this one for a good while and I'm getting really frustrated now! My problem is this - my custom controls periodically disappear from my project when I build it. First of I get the message about a missing dependency, then if I rebuild after that - the control just physically disappears from the form, and I get an object not found error when I run, (though sometimes when I rebuild the control can reappear) My background - I'm working in a small team of developers, we are using vb.net in visual studio with visual source safe. As I've said I've been battling with this for a while and have done some reading on this - I know that it is to do with references. Therefore I am trying to do what all the Microsoft articles I've read recommend with regard to references: - setting copy to local = true, using project references not file references, and setting the build order but to no avail. (Incidentally I still get this problem when using file references). Some more information - the custom controls are using a data access object, and this data access object is also being used by another object which the main form also uses. It is the reference to this data access object that is the one that that I get the message about the missing dependency. Please help - now to add insult to injury - I can not now even re-add my custom control from the toolbox. I can put it into the toolbox but when I try to drag it from the toolbox on to the form on nothing happens- not even a warning message. Many thanks Suzanne Tag: upgradation Tag: 62891

    - HELP - ".Net" user interface under Internet Explorer.. what to do ? Hello all, Once windows mmi programming was very easy - vb forms.. nice & easy. nowdays, our customers have became IE freaks !!! So, my question is, what is the best way to develop mmi in the ".Net" environment, over an intranet / lan environment. the first alternative is "Asp.Net".. though Microsoft is trying to push it very hard, to me the idea seems to be very wrong. I think that client code should be seperated from server code. Mixing client & server code (without even mentioning screen refreshe issues) does not feel right to me and my co-workers. The second alternative is pure html code (+xml islands). I dont like this idea... developing html in the 21 century seems a bit retro and difficult. My last alternative is ".Net Winforms" under IE. does anoyone has experience with this alternative? theoreticly it seems to be a perfect idea.. is it? Thanks in advance, Eran Eldor Tag: upgradation Tag: 62888

Actually, .NET Framework 1.0 and 1.1 can be installed side-by-side. You can
install from here:
