    - Overriding "OnXXX" versus adding event handler Okay, this has come up in the past but I haven't seen anything that I would call a good, solid general rule. The question applies more generally, but I'm going to ask in the context of a Control. How does one decide whether to write an "override" method to an event and when to simply add an event handler for that event? For example, you can either write a new OnPaint override, or you can register a delegate that the Control's base OnPaint method will execute. My current thought is that when you are not inheriting from the base class, you register a delegate (duh, since you obviously have no way to override the method in that case), and when you are inheriting from the base class, you override the method (the main reason here being that if you're inheriting from the base class, you want your new functionality to always work, rather than relying on your delegate remaining in the event handler list). In other words, override when you can, add an event handler if you can't. Is it really as simple as that? Or are there other factors I should be considering? Many thanks in advance for the wisdom of those who have gone down this road before me. :) Pete Tag: checkboxlist query Tag: 129495

    - convert an object to string and back (in a culture independent fashion) to store user preference in our application we have an 'hand written' XML file. (as opposed to XmlSerializer written one, which crash sometimes, on some user's computer, for some unknown reason.. but I'm digressing) In this XML file I store object value, which I convert to string (when writting) and from string (when reading) with a couple of simple function which (should) do a reversible conversion (using TypeConverter) (functions below). Unfortunately, for some Enum, (namely System.Windows.Forms.Keys) I got a culture dependent string, even though I specify CultureInfo.InvariantCulture as an argument in my ConvertXXX method with the TypeConverter. Even using 'new CultureInfo("en")' do not fix this behavior. Any tip on how to fix these function (below) so they provide a truly culture independent reversible object=>string=>object mechanism? =================================================== public static bool TryGetStringValue<T>(object val, out string ret) { if (val is string) { ret = (string)val; return true; } TypeConverter tc = TypeDescriptor.GetConverter(typeof(T)); if (tc == null) { ret = val.ToString(); return false; } try { ret = tc.ConvertToString(null, CultureInfo.InvariantCulture, val); return true; } catch (ArgumentException) { } catch (NotSupportedException) { } ret = val.ToString(); return false; } public static bool TryGetTValue<T>(object val, out T tval) { if (val is T) { tval = (T)val; return true; } TypeConverter tc = TypeDescriptor.GetConverter(typeof(T)); if (tc == null) { tval = default(T); return false; } if (!tc.IsValid(val)) { tval = default(T); return false; } try { tval = (T)tc.ConvertFrom(null, CultureInfo.InvariantCulture, val); return true; } catch (ArgumentException) { } catch (NotSupportedException) { } tval = default(T); return false; } =================================================== Tag: checkboxlist query Tag: 129493

    - Windows Workflow - What basic tutorials? What's going on here? I thought I was an experienced programmer but I'm looking at the beginning WWF tutorial (Simple Expense Report) and I'm baffled. I feel like I don't know how to even begin reading this. I thought this was supposed to be interactive coding. Since when do we cut and paste into a project file? Is this just a temporary Beta thing? Why this constant use of command prompts? Also I have downloaded other samples onto my machine and none of them seem to work correctly. In the OrderingStateMachine demo, I get the error message: "The project file <C:\data\Visual Studio 2005\OrderingStateMachine\VB\OrderWorkFlows\OrderWorkFlows.vbproj cannot be opened. The project type is not supported by this installation." ?????? Could someone direct me to a more user-friendly, comprehensible tutorial? Tag: checkboxlist query Tag: 129485

    - Truly cross platform? The thread bellow titled 'Determining if two paths are the same' brings to mind some of the first 'things' I had heard way back when DotNet started. It was going to be the panacea of cross platform development. I am asking the question here of the group to find out if everyone (anyone) thinks this has come (or is coming) to fruition. I think that perhaps it has gone a long way towards making it simpler to communicate between platforms but I am not sure if the framework itself has actually made it to the cross platform development hall of fame just yet. What do you folks think is the possibility of truly doing that? Looking at the mono project and actually trying to use it in some productive manner has showed me that this is far off. Just trying to get it working along with GDK and Mono-develop on a fedora Core 6 system was an exercise in futility. While I can understand what drives the open source community I honestly can't understand what keeps it going when stuff is that hard. I can install VS.NET 2005 and be developing in an hour. Hello world in Mono-develop never came to life. But, I digress and that is another rant for another message area. So, what are your thoughts and ideas? Tag: checkboxlist query Tag: 129483

    - Locking Desktop and Threading Issue Hi, I have an application that displays forms on the users desktop, what I am doing with it is having a SystemEvents SessionSwitchEventHandler to capture the lock of the desktop, I would like to kill the forms when this event is captured, that piece is fine, but I would like to sleep the app until the SessionSwitchReason.SessionUnlock happens then I can wake it again and go the correct part of the code? Can I wake a sleeping thread, or should I not sleep the thread at all, is there another way to get the thread to sleep or hibernate and then wake up? Thanks Eamonn Tag: checkboxlist query Tag: 129478

    - .Net Windows Service ...data access problem Hi, I am writing a .NET windows Service that will access the database every 10 minutes. When the service calls the function in the business services layer which in turn calls the correponding function in data access layer, this DAL function fails. The reason 'apparently' being that the it can not read the connection string information and hence can not create the database connection. Please note that that I am using enterprise library. All the projects representing business service layer, DAL, Model, Web UI and also the the windows service project are all in the same solution. Can anyone tell me what should I do to get around this problem. Thanks -Sam Tag: checkboxlist query Tag: 129470

    - Installation problem - MSDN Libs for VS2005 I'm trying to jury-rig an installation of MSDN for VS2005 from ISO disks. The company I'm working for has an 'install drive' so I'm not sure of the pedigree of these directories. Essentially, since I don't have a CD burner at my disposal, I'm trying to run the installation directly from the ISO images using Microsoft's Virtual CD-ROM Control Panel v2.0.1.1. The problem is as follows: It doesn't matter if I run the setup on the first MSDN disk or call MSDN installation directly from VS2005's setup screen. Either way I get an error message saying: "Error 1311. Source file not found. U:\_17693_RTL_x86_enu_NET_Framework_SDK_HxS.cab. Verify that the file exists and that you can access it." I should note that given the current mounting scheme, the 3 ISO images are disks T, U, and V and presumably software on the T drive should be running. So how could it know about the U drive in the first place and why didn't it issue a standard Insert Disk prompt? (The file definitely exists and I can even copy it.)

    - The Interlocked on the Edge of Forever I've got a quick question that's been bugging me for a long, long time: Let's say I've got a member variable (in a heavily threaded app): private int _firstTime = 0; To make changes to this is easy enough: InterlockedExchange(ref _firstTime, 1); ... or I can use the InterlockedCompareExchange: int oldValue = InterlockedCompareExchange(ref _firstTime, 1, 0); No problems here. ... but, if I just want to read the value, I CANNOT do: int myValue = _firstTime; or if (_fistTime==0) Doing these requires a memory barrier of some type (volatile variable, monitor, etc) to have any degree of reliability. Now, reading the value out using InterlockedCompareExchange always seemed a bit silly to me. I don't want to always write: int myValue = InterlockedCompareExchange(ref _firstTime, Int32.MinValue, Int32.MinValue); I've never found (although not for lack of looking): int myValue = InterlockedRead(ref _firstTime); Of the code that I write, reading the value, and branching based on it's value, is much more common than writing to the value. I have, in the past, used volitile variables for this - but I've stopped due to the various issues regarding volatiles (non atomic reads & writes). Is there a concensus on the best way to do this? It seems like all the solutions are.... incomplete. Essentially I'm looking for a volitile varaiable that is atomically read and written. Unfortuantly, these don't exist in any language I've yet used. -- Chris Mullins, MCSD.NET, MCPD:Enterprise, Microsoft C# MVP http://www.coversant.com/blogs/cmullins Tag: checkboxlist query Tag: 129446

    - How to tell which window becomes the foregroud window right away? Hello, I followed the MS instructions to subclass Windows using C#.net (http://support.microsoft.com/kb/815775) as the follows. I then opened several Excel files, and selected anyone of them as foreground window. I was expecting to see windows message, saying WM_ACTIVATE, or something like that, however, to my surprise, I saw NO windows message when I randomly selected those Excel windows, (although I could see other window messages, e.g., WM_GETTEXT). It was said that this was because "Subclassing this way only works for windows in its own process, not in other applications." Then, is there a way to make it work on other processes? Will automation will make the "other application" in the same process of our application? My goad is: Tell which (e.g. Excel) window becomes the active one AS SOON AS a (e.g. Excel) window becomes active. Thanks a lot. -------------------- Add a new Class module that is named SubclassHWND.cs to the Visual C# .NET or Visual C# 2005 application. To do this, click Add Class on the Project menu. 2.

    - DataSet fields not updating, no errors being generated I am using a web service to update some database fields. I used the dataset designer to define my datatable and tableadapter. I had it automatically create the insert, update, and delete statements. When I run the update method, all of the fields are updated except for four datetime fields. Another attribute these fields have in common is that they allow nulls. When the method runs, the values in the fields are not overwritten, they are simply not changed. Here is the code used for the updating: PurchaseOrderTableAdapter dAdapter = new PurchaseOrderTableAdapter(); PoDataSet.PurchaseOrderDataTable ds = dAdapter.GetDataByPoID(poID); foreach (PoDataSet.PurchaseOrderRow dataRow1 in ds) { dataRow1["PONumber"] = poNumber; dataRow1["ConfirmingTo"] = confirmingTo; dataRow1["poDate"] = poDate; dataRow1["ReqDate"] = reqDate; dataRow1["CancelDate"] = cancelDate; dataRow1["AllowBackOrder"] = allowBackOrder; dataRow1["ShipTo"] = shipTo; dataRow1["BillTo"] = billTo; dataRow1["ShipVia"] = shipVia; dataRow1["FOBPoint"] = fobPoint; dataRow1["Terms"] = terms; dataRow1["IsPlaced"] = isPlaced; dataRow1["placeDate"] = datePlaced; } try { dAdapter.Update(ds); } catch (Exception e) { return 1 + e.Message; } return "0"; I am new to C# and .net in general. Any ideas as to why this method is not updating the "placeDate", "poDate", "ReqDate", and "CancelDate" fields? The variables used are defined as DateTime types. As I said, there are no errors flagged during the process. Your advice is greatly appreciated. -- Alex Tag: checkboxlist query Tag: 129403

Yesterday, we received the following message "Transaction (Process ID 69) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction.

This command is not in a transaction, so the deadlock seems impossible. And moreover, the deadlock occurs on the DataReader.Read() not on the Command.ExecuteReader(...).

    - How to capture Item's event through an object of its collection in a external class? There are two classes 1) Key - contains some public variables, one method "Reset" and one event "valuesReset" which is raised by Reset method. 2) Keys - this class is collection of objects of class 'Key' and it is inherited with ReadOnlyCollection(Of key). I'm pasting the code here Class key Public Event valuesReset() Public _name As String = "" Public _title As Integer = 0 Public _strong As Integer = 0 Public _italic As Integer = 0 Public Function reset() As Boolean _name = "" _title = 0 _strong = 0 _italic = 0 RaiseEvent valuesReset() End Function End Class 'Collection of key Class keys Inherits ReadOnlyCollection(Of key) Friend Sub New() MyBase.New(New List(Of key)) End Sub Friend Function add(ByVal tmpKey As key) As Integer If Items.Contains(tmpKey) Then Return Items.IndexOf(tmpKey) End If Items.Add(tmpKey) Return Count - 1 End Function Friend Sub AddAt(ByVal tmpKey As key, ByVal index As Integer) If index < 0 OrElse index > Items.Count - 1 Then Return End If If Contains(tmpKey) Then Return End If Items.Insert(index, tmpKey) End Sub Friend Sub Dispose() For i As Integer = Count - 1 To 0 Step -1 Me(i).reset() Next End Sub Friend Sub remove(ByVal tmpKey As key) Items.Remove(tmpKey) End Sub End Class Class Form1 withevents objKeys as Keys ' I want to capture the "valuesReset" event here with the index number of the key type ' bject End Class Now the problem is how can I capture the event "valuesReset" of an key object if I use "withevents objKeys as Keys" in any form/outside class? and if it is possible how can I know which key object inside the collection has raised the event?

I try to get the property value on BindingChanged in my custom control, but, at that time, host UserControl is not completly loaded, so my property is NULL. I can't call a custom control's method from host UserControl. It would 'destroy' the automatic behaviour... How can I know in my custome control that the host UserControl has finished to load ?

    - why use .net? Hi there, We need to retrospectively justify our choice in using .NET framework for developing our site. Our techie isnt here so we cant run it past him. Can some kind, helpful person run their eye over it and tell me if I'm tellling porkies, or if there is anything I should add? Why should people choose .net (I think ours is 1.1) Thanks Gay ****************** We recognised that in order to meet our aims of producing a high quality and consistent website, we had to ensure that our system was fast, robust and able to deal with a high number of users. We chose .NET framework so that we could meet these needs now, but also so that we could best account for any future developments in a cost effective manner. This has proved the case, in that with our Stage 2 developments we will be implementing a forum system. Using .NET has meant that we can integrate new modules with ease. With .NET's cross-platform interconnectivity, we feel that we have chosen the best approach for future-proofing. Tag: checkboxlist query Tag: 129346

    - Piped input contains Unicode preamble I'm an old dog and I like old tricks, so I write a lot of utilities that accept piped input. e.g. TYPE mydata.txt | MyApp or MyApp < mydata.txt or App1 | App2 Then read the input with System.Console.In What I found though is that if the input file contains a Unicode preamble (i.e. EF BB BF for UTF-8) the preamble appears in the data, which is inconvenient. I'm not real interested in _why_ this is the case, but I wonder what others do to resolve this. So far, because I'm only concerned with "ASCII" text, I simply ignore all characters above 7F, but I'd like a more elegant solution. One other thing I tried was rather than use System.Console.In I tried new System.IO.StreamReader ( System.Console.OpenStandardInput , true ) which worked some times, but other times was missing the beginning of the data (which I assume is due to buffering).

    - Custom app and Korean I have an application written in .NET, running under Windows XP SP2 and Windows Server 2003 with SQL Server 2000 as the backend. This app basically indexes documents to allow keyword searching. We now need to load and index Korean language documents, but I have absolutely no idea what would be necessary to accomplish this. First off, we do use a third party product to perform the indexing, and I know that it supports Unicode. Any pointers and assistance would be appreciated. Michael Tag: checkboxlist query Tag: 129338

I am writing an app that is required to connect to various network resources without knowing whether those resources are connected before hand. I also need the functionality of being able to provide profile/password information when attempting to access the network resources.

    - Network communication with Windows Services Hello, I am designing an system where Windows services (clients) are distributed across a company LAN. The clients are written in Win32 since not all network machines may not have .NET Framework installed. The clients connect to a central SQL database to report relavent status information from the network machines. There is a WinForms application that monitors and provides results of the distributes clients to an operator. The application also allows the operator to deploy the clients to the remote machines via Windows Networking APIs, or externally using Active Directory and a supplied Windows Installer Package that installs the Windows Service client out to the network. The target network(s) are Windows based using Active Directory. The client machines are Windows 98 and above....however, we may limit the requirements to only support Windows 2000 and above if necessary. I was hoping some of you can provide your opinions on the following questions: 1) Given the above design/architecture, do you think there are other or better methods for implementing the system? ie, any other technologies that would better suite the situation other than each client directly connecting to SQL Server... 2) Please comment on the idea of using a web service (installed on the database server) for clients to connect to provide status information? 3) Are there other or better technologies for distributing the Windows Service clients outside of the ones mentioned above? Note, this system will be used on a broad range of networks that may not have specific technologies in production. Thanks in advance for your input. Its always good to get other opinions.

After you add the items in the checkedlistbox, use the SetCheckState or
SetItemCheckState methods to check the item.
