    - Merging Visual Studio & SDK Help Hi all, I recently installed windows workflow foundation and then realized that I could no longer see .NET framework documentation in my MSDN help. I installed the SDK hoping that it would merge back in. However, I now have two separate help collections, one with the framework classes etc... the other with all other documentation. Is there anyway to merge these two collections together? Is there any type of utility that will allow me to easily see what help is installed and manage it in some form or fashion? Thanks, Cole Tag: checkboxlist query Tag: 129587

    - My manifest loading a reference twice im getting the ol' Could not load file or assembly 'ComponentArt.Charting.WebChart, Version=2007.1.1052.2, Culture=neutral, PublicKeyToken=9bc9f846553156bb' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. as you can see the .net framework wants to use version 2007.1.1052.2 of my 3rd party dll. I recently upgraded the 3rd party dll and expect .net to try and use 2007.1.1126.2 I have tried everything, removing / readding the reference, checking the gacutil (which does not list this assembly) even unloading iis and anything that is running the project before removing/readding this reference. Upon viewing my manifest for the project i see that this reference is being loaded twice .assembly extern ComponentArt.Charting.WebChart { .publickeytoken = (9B C9 F8 46 55 31 56 BB ) // ...FU1V. .ver 2007:1:1126:2 } this looks good, i see the version i want in the manifest, scroll a bit further and i find this .assembly extern ComponentArt.Charting.WebChart as ComponentArt.Charting.WebChart_19 { .publickeytoken = (9B C9 F8 46 55 31 56 BB ) // ...FU1V. .ver 2007:1:1052:2 } why is this in there? it is the wrong version, with the same publickeytoken and some kind or renamed reference to WebChart_19 Im guessing this is my problem, but this 4 lines of text seems impossible to get rid of... Any ideas would be very helpful thanks Tag: checkboxlist query Tag: 129585

    - Using cacheing?? Iâ??m researching the idea of using caching in my application. And I wanted to get other people thoughts that have used it with .NET 2.0. Below is an explanation of the current process: I have an application with several web pages. When any of these pages is first loaded, it retrieves the information from SQL and stores the information in a DataSet. This DataSet is then converted to a Session variable so that it can be used over and over without the need to reconnect to the database to refresh the data. The only time connections to SQL are made is when the user requests to DELETE or UPDATE the physical records. Once the delete/update is complete, I convert the Session variable back to a dataset and perform the same action on the dataset. Next I rebind the dataset back to the control and redisplay the page. All works great and it is fast. But it takes a lot of memory to store those datasets for each user session. Not to mention that if user(A) makes a change to a record, and user (B) is view the same record, b/c they are session variables, user (B) will never see user (A) changes. So I wanted to try using disk caching where user (A) requests a record, it gets cached on the server hard drive. SQL update and deletes happen as they do now, but I update the cache instead of a dataset in memory. If user (B) accesses the same record, and this record is already in cache from another user, it reads the cache instead of connecting to SQL to issue the SELECT statements. This cache would need to reside on the drive for say 24 hrs. All this to say, have any of you done anything similar? What are thing things I should watch out for? Whatâ??s a good resource to get started using this method in C#. I know disk I/O is slower then memory, but its faster then connecting to SQL every time to refresh the data. -- JP .NET Software Developer Tag: checkboxlist query Tag: 129577

    - Programmatic diagnostic questions about dlls Hi, I am currently working on a diagnostic utility for developers, and some of the things I want to check are whether a dll in a project output folder is locked and cannot be over-written, or if an incorret version of a dll has been cached in the temporary internet files folder. A friend said that I could possibly open a file stream on a dll, and attempt to lock it, and if it failed, it would give info on which process currently had it locked, which might solve the first requirement - does anyone else have any ideas or suggestions on this? As for checking for cached dlls, I was thinking that I could maybe use reflection on the dlls in the temp inet folder to check for inconsistent dll versions, but I'm not sure if this is the best approach, or would even work - suggestions?

    - Is This Overkill? I've been maintaining some source code, and I've noticed some radical inconsistency in the code, particularly in the way that parameters are validated. I've noticed that this seems to have been pretty much the case throughout my career. For instance, consider the following block: If siteId <= 0 Then Throw New ArgumentOutOfRangeException("siteId") End If If name Is Nothing Then Throw New ArgumentNullException("name") End If If name = String.Empty Then Throw New ArgumentException("Empty strings are not permitted.", "name") End If If buildingIdToIgnore < -1 Then Throw New ArgumentOutOfRangeException("buildingIdToIgnore") End If Sometimes, this code is collapsed as follows: If siteId <= 0 Then Throw New ArgumentOutOfRangeException("siteId") If name Is Nothing Then Throw New ArgumentNullException("name") If name = String.Empty Then Throw New ArgumentException("Empty strings are not permitted.", "name") If buildingIdToIgnore < -1 Then Throw New ArgumentOutOfRangeException("buildingIdToIgnore") Sometimes, it's omitted altogether. Somtimes, not all of the parameters to the procedure are validated. And in many cases, the messages aren't consistent from one parameter validation to the next. (Resource files would go a long way towards solving that, but that's a whole different thread.) What I've been pondering for some time is a way to make it easier to validate method parameters. My *theory* is that it's a lot of gangly code to write If...Then...Throw...End If, which leads to short-cuts and, eventually, outright omissions. So, a way to abbreviate that and make the code clearer might help to encourage consistent use of parameter validation, which should (in theory) improve code quality throughout the system. So I have this model I'm working on, and before I go completely off the deep end with it, I thought I'd run it by you to see what you thought of it. Essentially, it's based on NUnit asserts to validate parameters consistently and clearly. So, the code above is changed to this: Validate.That(siteId, "siteId").IsNotNegative() Validate.That(name, "name").IsNotNullOrEmpty() Validate.That(buildingIdToIgnore, "buildingIdToIgnore").IsGreaterThan(-2) Validate.That(connection).IsOpenAndIsNotNull() My tests for the model are going very well. I think that once I get it going, it could provide a very cool, extensible validation framework for parameters. The "framework" is in a separate class library, and the messages are in a string resource file, providing consistency. The big caveat, of course, is that there's no guarantee that it solves the *enforcement* problem. There's also the problem that FxCop thinks I'm not validating parameters when I am. So the question I have is, is this even worth doing? When an existing code base is refactored to use it, it looks much cleaner, and appears to be easier to read and maintain. But the question remains: is this a real problem, or am I addressing an issue that doesn't really exist? Your input is greatly appreciated. Thanks! Tag: checkboxlist query Tag: 129567

    - DataTable.Merge() I'm a little confused about DataTable.Merge(). I have two DataTable objects with the same structure - dtOrig and dtCurrent. The end result I'm trying to achieve is to get all the rows in dtCurrent that are in some way different from the corresponding rows in dtOrig so those new/ modified/deleted rows can be processed. My idea was to use dtOrig.Merge(dtCurrent), and then call dtOrig.GetChanges(). But what I found is that when the preserveChanges Merge() parameter is 'false' (or not supplied) the values in dtOrig do get updated, but the RowState stays 'Unchanged'. When preserveChanges is 'true' then the RowState for all rows becomes 'Modified' but the values in dtOrig are NOT actually updated! What am I missing here? Is there a better way to go about this?

    - SslStream caching and Vista: Hi. When my client program runs under XP and calls a server (solaris in this case) via an SslStream all is well. The client may make multiple calls and multiple authentication calls and be fine. Running the client under Vista, when the second authentication call is made it returns the following SSPI error: "A call to the SSPI failed, see inner exception" which reads "the Local Security Authority cannot be contacted" Well that was pretty mystifying so I looked at what was going on with ethereal. Apparently, on the second authentication go-round the client asks the server to re-use a session Id. The client responds and then Vista rejects a re-used session Id (even though it asked to do that). What I have found out is that the .net framework seems to cache SslStream sessions automatically, I have not found any way to turn this off for Vista - any ideas on how to do this?

    - 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

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.)

    - Questions about clickOnce hi, I have couple of questions about clickonce again, I am publishing a Winform appplication using ClickOnce. In the 'Publishing Location' text box I input the directory name (C:\CLICKONCE\Test2\). In the 'Installation URL' what shall i input. Why do i need to input a URL when it is simple Winform Application. Question2: When I publish a new version, The client should be prompted about the new version and it should run that instead of old one. It doesnt do it in my case, even though 'Application Should check for updates' is ON. Thanks in Advance irfan Tag: checkboxlist query Tag: 129464

    - 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

    - tcpclient connect security exception - unauthorized Hi all, I have a tcpclient and server setup client and server both different machines. The client when run under administrator credentials connects fine, but when run under normal user, the tcpclient connect is refused with unauthorised. All of this is on same netword/domain. The client is running localy not a network share and connects to specific IP Adress on specific port. The ony difference between connecting and not is the credentials...... Is this .NET Casol as the socket is accessed, if so how do I resolve it, or are we looking at windows user permissions? Any help greatly appreciated... Pete Tag: checkboxlist query Tag: 129445

    - 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. In the Name text box, type SubclassHWND.cs, and then click Open. 3. Replace the SubclassHWND class code with the following code:public class SubclassHWND : NativeWindow { protected override void WndProc(ref Message m) { // Perform whatever custom processing you must have for this message System.Diagnostics.Debug.WriteLine(m.ToString()); // forward message to base WndProc base.WndProc(ref m); } } 4. To demonstrate its use, add the following code to the Load event of Form1:SubclassHWND s = new SubclassHWND(); s.AssignHandle(this.Handle); //Now s should be listening to the messages of the form.

    - Determining if two paths are the same Hi there, Given two file names in relative or absolute format, I need to determine if they point to the same file. While I can simply pass each to "Path.GetFullPath()" and compare the results, what is the rule regarding case. That is, how do you determine whether the local file system is case-sensitive or not. I don't want to assume that Windows is the target OS even though realistically it will be. Thanks. Tag: checkboxlist query Tag: 129438
