  • Parsing an XML string containing "&#x20;" (which must be preserved)

    - by Zoodor
    I have code that is passed a string containing XML. This XML may contain one or more instances of &#x20; (an entity reference for the blank space character). I have a requirement that these references should not be resolved (i.e. they should not be replaced with an actual space character). Is there any way for me to achieve this? Basically, given a string containing the XML: <pattern value="[A-Z0-9&#x20;]" /> I do not want it to be converted to: <pattern value="[A-Z0-9 ]" /> (What I am actually trying to achieve is to simply take an XML string and write it to a "pretty-printed" file. This is having the side-effect of resolving occurrences of &#x20; in the string to a single space character, which need to be preserved. The reason for this requirement is that the written XML document must conform to an externally-defined specification.) I have tried creating a sub-class of XmlTextReader to read from the XML string and overriding the ResolveEntity() method, but this isn't called. I have also tried assigning a custom XmlResolver.

  • Supersized, show a div depending on the slide

    - by Dlacrem
    EDIT: So, I want to take a different approach to try and clarify what I'm looking for, I've been reading as much as I could these last hours and I feel I have a better grasp of how the system works, but I still don't know how to accomplish my goal. Reference links: -SUPERSIZED API So, I have the following script: <script type="text/javascript"> $(document.body).ready(function () { if (vars.current_slide == 5){**-I want it to display a div if the slider is the number 5-** } }); </script> My questions are these: 1) What do I add in the - - area to display a div that only shows up when the slider is at the 5th slide? 2) Am I doing the rest right or am I missing something? I created that code so it could be terribly wrong lol, hopefuly I got something right :P That's all, hope this clarifies it. Thank you all for the help! I'm really excited to start creating my own scripts :D Alright, so I've uploaded the site with the code you posted and it still doesn't seem to work, I also tried reducing the code to the conditional and the result only but that didn't work either, mind checking it out? Click Here Thanks for giving it a thought!

  • I need to move a dived CSS module into the center of the page...

    - by JackMcE
    I'm building a website for someone and they wanted the text and bulk of the information to be centered on the page. Problem is I can get everything contained in a tag and then assign the class, but I can't get the whole thing to center. It always hangs to the left even if I apply centering to the div class. I guess you could say that it is stuck on the left side of the page when I want everything to be centered. I would just make everything format larger but they want some space left in the background for the color and maybe some imagery later on. They haven't made up their minds. If you want to take a look here is the link where I'm building or testing stuff. I know the header and such needs to be re proportioned to fit with everything, but just as a frame of reference. Don't worry about the header, just know that I want the white text information area with the purple border to stay the same size, but just move to the center and if some one could tell me how to do that I would appreciate it greatly.

  • The cross-thread usage of "HttpContext.Current" property and related things

    - by smwikipedia
    I read from < Essential ASP.NET with Examples in C# the following statement: Another useful property to know about is the static Current property of the HttpContext class. This property always points to the current instance of the HttpContext class for the request being serviced. This can be convenient if you are writing helper classes that will be used from pages or other pipeline classes and may need to access the context for whatever reason. By using the static Current property to retrieve the context, you can avoid passing a reference to it to helper classes. For example, the class shown in Listing 4-1 uses the Current property of the context to access the QueryString and print something to the current response buffer. Note that for this static property to be correctly initialized, the caller must be executing on the original request thread, so if you have spawned additional threads to perform work during a request, you must take care to provide access to the context class yourself. I am wondering about the root cause of the bold part, and one thing leads to another, here is my thoughts: We know that a process can have multiple threads. Each of these threads have their own stacks, respectively. These threads also have access to a shared memory area, the heap. The stack then, as I understand it, is kind of where all the context for that thread is stored. For a thread to access something in the heap it must use a pointer, and the pointer is stored on its stack. So when we make some cross-thread calls, we must make sure that all the necessary context info is passed from the caller thread's stack to the callee thread's stack. But I am not quite sure if I made any mistake. Any comments will be deeply appreciated. Thanks. ADD Here the stack is limited to user stack.

  • What's wrong (or right) with this JS Object Pattern?

    - by unsane1
    Here's an example of the pattern I'm using in my javascript objects these days (this example relies on jQuery). http://pastie.org/private/ryn0m1gnjsxdos9onsyxg It works for me reasonably well, but I'm guessing there's something wrong, or at least sub-optimal about it, I'm just curious to get people's opinions. Here's a smaller, inline example of it: sample = function(attach) { // set internal reference to self var self = this; // public variable(s) self.iAmPublic = true; // private variable(s) var debug = false; var host = attach; var pane = { element: false, display: false } // public function(s) self.show = function() { if (!pane.display) { position(); $(pane.element).show('fast'); pane.display = true; } } self.hide = function() { if (pane.display) { $(pane.element).hide('fast'); pane.display = false; } } // private function(s) function init () { // do whatever stuff is needed on instantiation of this object // like perhaps positioning a hidden div pane.element = document.createElement('div'); return self; } function position() { var h = { 'h': $(host).outerHeight(), 'w': $(host).outerWidth(), 'pos': $(host).offset() }; var p = { 'w': $(pane.element).outerWidth() }; $(pane.element).css({ top: h.pos.top + (h.h-1), left: h.pos.left + ((h.w - p.w) / 2) }); } function log () { if (debug) { console.log(arguments); } } // on-instantiation let's set ourselves up return init(); } I'm really curious to get people's thoughts on this.

  • SQL Server 2008, Books Online, and old documentation...

    - by Chris J
    [I have no idea if stackoverflow really is right right place for this, but don't know how many devs on here run into msi issues with SQL Server; suggest SuperUser or ServerFault if folk think it's better on either of those] About a year ago, when we were looking at moving our codebase forward and migrating to SQL Server 2008, I pulled down a copy of Books Online from the MSDN. Reviewed, did background research, fed results upstream, grabbed Express and tinkered with that. Then we got the nod to move forward (hurrah!) this past couple of weeks. So armed with Developer Edition, and running through the install, I've since found out I've zapped the Books Online MSI, no-ones got a copy of it, and Microsoft only have a later version (Oct 2009) available, so damned if I can update my SQL Server fully and properly... {mutter grumble}. Does anyone know if old versions of Books Online are available for download anywhere? Poking around the Microsoft download centre can't find it, neither is my google-fu finding it. For reference, I'm looking for SQLServer2008_BOL_August2008_ENU.msi ... This may just be a case of good ol' manual delete the files and (try) and clean up the registry :-(

  • Why would gnu ld link order causes Signal 11 (SEGV) on startup?

    - by Benoit
    We are building a large application in C++ that includes the use of many (static) libraries. We have a problem where the application crashes on startup with a Signal 11, before we even reach main. After much debugging, we have observed that if we explicitly reference an object file so its link order is early, the program crashes on startup. If the file is referenced later (or not referenced at all), the program does not crash. To be clear, there is NO code invoked directly from this object file. However, as it is C++, there might be static objects that do get constructed (it's a CORBA IDL generated file). We use the -Wl,--start-group ... --end-group arguments to multi-pass link the symbols since the libraries are interdependent. Here is a representation of what I mean. This is what the linker's object file order is: Order 1 Order 2 Order 3 foo.o foo.o foo.o ... ... ... main.o main.o main.o crasher.o libA.o libA.o libA.o LibB.o LibB.o LibB.o LibC.o LibC.o LibC.o crasher.o Results: NO CRASH NO CRASH CRASH Does any one have an idea why the linkage order has an effect on the crash? It would be nice if we could force the crasher.o to link later, but we're really after an explanation. Also, is there a way to force the linker to place crasher.o towards the end? Just to add to the fun, in actuality, crasher.o is part of a Library in the --start/--end-group.

  • When are temporaries created as part of a function call destroyed?

    - by Michael Mrozek
    Is a temporary created as part of an argument to a function call guaranteed to stay around until the called function ends, even if the temporary isn't passed directly to the function? There's virtually no chance that was coherent, so here's an example: class A { public: A(int x) : x(x) {printf("Constructed A(%d)\n", x);} ~A() {printf("Destroyed A\n");} int x; int* y() {return &x;} }; void foo(int* bar) { printf("foo(): %d\n", *bar); } int main(int argc, char** argv) { foo(A(4).y()); } If A(4) were passed directly to foo it would definitely not be destroyed until after the foo call ended, but instead I'm calling a method on the temporary and losing any reference to it. I would instinctively think the temporary A would be destroyed before foo even starts, but testing with GCC 4.3.4 shows it isn't; the output is: Constructed A(4) foo(): 4 Destroyed A The question is, is GCC's behavior guaranteed by the spec? Or is a compiler allowed to destroy the temporary A before the call to foo, invaliding the pointer to its member I'm using?

  • How can I create dynamically updated views in a tab bar view, based on settings selection?

    - by Diggers
    Hi all, Noob question.... I've created a Tab Bar application. It has four tabs and works fine. Each view is created with a XIB and is effectively static. Each view takes user input and responds on screen. What I need to be able to do is change the input options the user have - in effect remove some UITextFields dependant upon which option the user selects in settings. I've created root.plist and created settings no problem i've also created additional XIBS for the altered UI, but what I don't know how to do, is call these into the tab view controller on demand. Effectively tab one has 3 possible views, tab two 3 possible views etc. But I only want the one that's relevant for the users settings selction to be displayed? Make sense? For reference, if we call the different views - UIInputViewA1, ...A2,....A3 UIInputViewB1,....B2....B3 etc. Hope someone can help, been trawling the net for nights trying to get my head round this. Beggining iPhone Development Bible doesn't help either. If you need any more info, please shout. Cheers Paul.

  • Watching variables in SSIS during debug

    - by Tom H.
    I have a project in SSIS and I've added an Execute SQL Task which sends its result out to a variable. I wanted to confirm the value because I was worried that it would try to write it out as a resultset object rather than an actual integer (in this case I'm returning a COUNT). My first thought was just to run it in debug mode and add the global variable to my Watch window. Unfortunately, when I right-click on the Watch window, the option to "Add Variable" is greyed out. What am I missing here? I've gotten around confirming that my variable is set correctly, so I'm not interested in methods like putting a script in to do a MsgBox with the value or anything like that. For future reference I'd like to be able to watch variables in debug mode. If there are some kind of constraints on that then I'd like to know the what and why of it all if anyone knows. The help is woefully inadequate on this one and every "tutorial" that I can find just says, "Add the variable to the Watch window and debug" as though there should never be a problem doing that. Thanks for any insight!

  • LLVM/Clang bug found in convenience method and NSClassFromString(...) alloc/release

    - by pirags
    I am analyzing Objective-C iPhone project with LLVM/Clang static analyzer. I keep getting two reported bugs, but I am pretty sure that the code is correct. 1) Convenience method. + (UILabel *)simpleLabel { UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(100, 10, 200, 25)]; label.adjustsFontSizeToFitWidth = YES; [label autorelease]; // Object with +0 retain counts returned to caller where a +1 (owning) retain count is expected. return label; } 2) The [NSClassFromString(...) alloc] returns retainCount + 1. Am I right? Class detailsViewControllerClass = NSClassFromString(self.detailsViewControllerName); UIViewController *detailsViewController = [[detailsViewControllerClass alloc] performSelector:@selector(initWithAdditive:) withObject:additive]; [self.parentController.navigationController pushViewController:detailsViewController animated:YES]; [detailsViewController release]; // Incorrect decrement of the reference count of an object is not owned... Are these some Clang issues or I am totally mistaken in these both cases?

  • A generic Re-usable C# Property Parser utility

    - by Shyam K Pananghat
    This is about a utility i have happened to write which can parse through the properties of a data contracts at runtime using reflection. The input required is a look like XPath string. since this is using reflection, you dont have to add the reference to any of your data contracts thus making pure generic and re- usable.. you can read about this and get the full c# sourcecode here. Property-Parser-A-C-utility-to-retrieve-values-from-any-Net-Data-contracts-at-runtime Now about the doubts which i have about this utility. i am using this utility enormously i many places of my code I am using Regex repetedly inside a recursion method. does this affect the memmory usage or GC collection badly ?do i have to dispose this manually. if yes how ?. The statements like obj.GetType().GetProperty() and obj.GetType().GetField() returns .net "object" which makes difficult or imposible to introduce generics here. Does this cause to have any overheads like boxing ? on an overall, please suggest to make this utility performance efficient and more light weight on memmory

  • When my object is no longer referenced why do its events continue to run?

    - by Ryan Peschel
    Say I am making a game and have a base Buff class. I may also have a subclass named ThornsBuff which subscribes to the Player class's Damaged event. The Player may have a list of Buffs and one of them may be the ThornsBuff. For example: Test Class Player player = new Player(); player.ActiveBuffs.Add(new ThornsBuff(player)); ThornsBuff Class public ThornsBuff(Player player) { player.DamageTaken += player_DamageTaken; } private void player_DamageTaken(MessagePlayerDamaged m) { m.Assailant.Stats.Health -= (int)(m.DamageAmount * .25); } This is all to illustrate an example. If I were to remove the buff from the list, the event is not detached. Even though the player no longer has the buff, the event is still executed as if he did. Now, I could have a Dispel method to unregister the event, but that forces the developer to call Dispel in addition to removing the Buff from the list. What if they forget, increased coupling, etc. What I don't understand is why the event doesn't detatch itself automatically when the Buff is removed from the list. The Buff only existed in the list and that is its one reference. After it is removed shouldn't the event be detached? I tried adding the detaching code to the finalizer of the Buff but that didn't fix it either. The event is still running even after it has 0 references. I suppose it is because the garbage collector had not run yet? Is there any way to make it automatic and instant so that when the object has no references all its events are unregisted? Thanks.

  • Arrays (toString) not output correctly

    - by DiscoDude
    Hello, Actually this tread is continuing from the other one. There wasn't enough characters to continue there. Anyway. the problem is that the output is "1(10) 2(23) 3(29)". Even though I could return string for the array values (10,23,29) and used string reference as 1, 2 and 3. My question is it possible to return index values 1,2,3 and as well as array values. Am I making an sense. Here is what I have done... // int[] groups = {10, 23, 29}; in the constructor String tempA = ""; String tempB = " "; int[] temp = new int[4]; int length = groups.length; for (int j = 0; j < length; j++) { temp[j] = groups[j]; tempB = tempB + "("+goups+")"; } groups = temp; Arrays.sort(coingroups); for(int i = 1; i < groups.length;i++) { tempA = tempA+" "+(i)+ "("+groups[i]+")"; } return tempA;

  • Mutate an object into an instance of one its subclasses

    - by Gohu
    Hi, Is it possible to mutate an object into an instance of a derived class of the initial's object class? Something like: class Base(): def __init__(self): self.a = 1 def mutate(self): self = Derived() class Derived(Base): def __init__(self): self.b = 2 But that doesn't work. >>> obj = Base() >>> obj.mutate() >>> obj.a 1 >>> obj.b AttributeError... If this isn't possible, how should I do otherwise? My problem is the following: My Base class is like a "summary", and the Derived class is the "whole thing". Of course getting the "whole thing" is a bit expensive so working on summaries as long as it is possible is the point of having these two classes. But you should be able to get it if you want, and then there's no point in having the summary anymore, so every reference to the summary should now be (or contain, at least) the whole thing. I guess I would have to create a class that can hold both, right? class Thing(): def __init__(self): self.summary = Summary() self.whole = None def get_whole_thing(self): self.whole = Whole()

  • Book Recomendations: WPF/Silverlight for Business(smallish, internal) Environment

    - by Refracted Paladin
    Yes, I know there are an insane amount of Book posts here(SO) but none I believe for my specific need. If there is and I missed it I apologize. I am the only developer at a non-profit organization(~200 employees) where we are a M$ shop and 90% of the things I develop are specific to our company and are internal only. I am given a lot of latitude on how I accomplish my goals so using new technologies is in my best interest. So far I have developed all winform & asp.net applications but I am an expert by NO MEANS. I would now like to focus on XAML driven development(WPF & Silverlight) but I have no idea where to start. I am subscribed to numerous Silverlight blogs and I have went through a few good tutorials however, I would really appreciate a GOOD SOLID book in my hands going forward. I prefer learning books versus reference books and I REALLY would like one from a Business standpoint as well. Shameless, self-promoting is welcomed if you happen to be an author or reviewer for one that meets my criteria. I would, however, prefer that recomendations were based on first-hand experience(no, 'my friend as this awesome book he told me about', please). If more info is needed to provide accurate recomendations please let me know. Thanks

  • Call c++ library from c#

    - by Batul
    Hello All, This question might seem a repeat of previous ones. I have read through a series of posts, but not completely clear for my situation. I have a c++ library which is created using momentics IDE. I have to be able to use this library into a c# project. Someone had been working on this project before being handed over to me. Currently, there are 2 layers for making this possible. First, a c++ project includes the complete library with a c++ wrapper. This project creates a dll as the output. This c++ dll is then fed to a c# project, which has dllimport calls to the c++ dll. This c# project again creates a dll. Finally, in order to use the library in c# application, I have to include a reference to both of these dlls. Is this the correct way to get it working? I was thinking probably there should be a way to simplify the process. Can someone please help me with this question?

  • SAS V9.1.3 - Error when combining %INC and CALL EXECUTE

    Hi, I am getting a resolution error with some SAS v9.1.3 code. Here is some code I want to store in a .txt file (called problem2.txt) and bring into SAS with a %INC %macro email020; %if &email = 1 %then %do; %put THIS RESOLVED AT 1; %end; %else %if &email = 2 %then %do; %put THIS RESOVLED AT 2; %end; %put _user_; %mend email020; %email020; Then this is the main code: filename problem2 'C:\Documents and Settings\Mark\My Documents\problem2.txt'; %macro report1; %let email = 1; %inc problem2; %mend report1; %macro report2 (inc); %let email = 2; %inc problem2; %mend report2; data test; run = 'YES'; run; data _null_; set test; call execute("%report1"); call execute("%report2"); run; The log shows: NOTE: CALL EXECUTE generated line. 1 + %inc problem2; MLOGIC(EMAIL020): Beginning execution.

  • Oracle Blob as img src in PHP page

    - by menkes
    I have a site that currently uses images on a file server. The images appear on a page where the user can drag and drop each as is needed. This is done with jQuery and the images are enclosed in a list. Each image is pretty standard: <img src='//network_path/image.png' height='80px'> Now however I need to reference images stored as a BLOB in an Oracle database (no choice on this, so not a merit discussion). I have no problem retrieving the BLOB and displaying on it's own using: $sql = "SELECT image FROM images WHERE image_id = 123"; $stid = oci_parse($conn, $sql); oci_execute($stid); $row = oci_fetch_array($stid, OCI_ASSOC+OCI_RETURN_NULLS); $img = $row['IMAGE']->load(); header("Content-type: image/jpeg"); print $img; But I need to [efficiently] get that image as the src attribute of the img tag. I tried imagecreatefromstring() but that just returns the image in the browser, ignoring the other html. I looked at data uri, but the IE8 size limit rules that out. So now I am kind of stuck. My searches keep coming up with using a src attribute that loads another page that contains the image. But I need the image itself to actually show on the page. (Note: I say image, meaning at least one image but as many as eight on a page). Any help would be greatly appreciated.

  • [PHP] Does unsetting array values during iterating save on memory?

    - by saturn_rising
    Hello fellow code warriors, This is a simple programming question, coming from my lack of knowledge of how PHP handles array copying and unsetting during a foreach loop. It's like this, I have an array that comes to me from an outside source formatted in a way I want to change. A simple example would be: $myData = array('Key1' => array('value1', 'value2')); But what I want would be something like: $myData = array([0] => array('MyKey' => array('Key1' => array('value1', 'value2')))); So I take the first $myData and format it like the second $myData. I'm totally fine with my formatting algorithm. My question lies in finding a way to conserve memory since these arrays might get a little unwieldy. So, during my foreach loop I copy the current array value(s) into the new format, then I unset the value I'm working with from the original array. E.g.: $formattedData = array(); foreach ($myData as $key => $val) { // do some formatting here, copy to $reformattedVal $formattedData[] = $reformattedVal; unset($myData[$key]); } Is the call to unset() a good idea here? I.e., does it conserve memory since I have copied the data and no longer need the original value? Or, does PHP automatically garbage collect the data since I don't reference it in any subsequent code? The code runs fine, and so far my datasets have been too negligible in size to test for performance differences. I just don't know if I'm setting myself up for some weird bugs or CPU hits later on. Thanks for any insights. -sR

  • Desperate help using PHP's $_SERVER["DOCUMENT_ROOT"] on a web server?

    - by Nickersoft
    I've spent the past few months building a website on localhost. Throughout the site, instead of using relative paths, I used $_SERVER["DOCUMENT_ROOT"] to access the root of my server so I could reference files from there. However, I just decided to upload my site to 000webhost. As I soon found out, and for those of you who use them, you are probably aware, that their server root is different than your actual directory in which you upload your files. I believe it's virtual hosting... anyway, my $_SERVER["DOCUMENT_ROOT"] now throws errors along the lines of this on the site: Warning: include_once() [function.include-once]: open_basedir restriction in effect. File(/usr/local/apache/htdocs/mypath) is not within the allowed path(s) Every other site I looked at said that you should just replace $_SERVER["DOCUMENT_ROOT"] with the home directory provided to you by 000webhost. However, if I want to change hosting services in the future, I'm screwed. Is there any way to use $_SERVER to access a set virtual directory or use htaccess or something to make my code work? I tried using DocumentRoot in a htaccess file in my root directory, but it threw a 404 error when trying to access the page. I'm in desperate need... can anyone help me?

  • '??' Not a valid unicode character, but in the unicode character set?

    - by Steve Cotner
    Short story: I can't get an entity like '𠂉' to store in a MySQL database, either by using a text field in a Ruby on Rails app (with default UTF-8 encoding) or by inputting it directly with a MySQL GUI app. As far as I can tell, all Chinese characters and radicals can be entered into the database without problem, but not these rarely typed 'character components.' The character mentioned above is unicode U+20089 and html entity &#131209; I can get it to display on the page by entering <html>&#131209;</html> and removing html escaping, but I would like to store it simply as the unicode character and keep the html escaping in place. There are many other Chinese 'components' (parts of full characters, generally consisting of 2 or 3 strokes) that cause the same problem. According to this page, the character mentioned is in the UTF-8 charset: http://www.fileformat.info/info/unicode/char/20089/charset_support.htm But on the neighboring '...20089/index.htm' page, there's an alert saying it's not a valid unicode character. For reference, that entity can be found in Mac OS X by searching through the character palette (international menu, "Show Character Palette"), searching by radical, and looking under the '?' radical. Apologies if this is too open-ended... can a character like this be stored in a UTF-8-based database? How is this character both supported and unsupported, both present in the character set and not valid?

  • MS Ajax Libraries and Configured Assemblies

    - by smehaffie
    Use Case You have a brand new IIS servers that has .Net 3.5 installed and are migrating sites to the new servers.  In the process of migrating sites you come across some sites that get an error about the version of AJAX libraries being references in the web.config.  In the web.config all the entries reference 1.0.61025.0, but the older version of the AJAX libraries are not installed on the new servers, only the latest version is installed that comes with .Net 3.5.  So what are the options to fix this issue. Solutions 1) Install the older version of the AJAX Libraries: Although this works, IMO it is never a great idea to install an older version of a library after a newer version has been installed.  Plus, if all new application use the latest versions, is it worth the effort of installing the older version for a few legacy applications? 2) Update the web.config files so all references use latest version (3.5.0.0):  This option is very time consuming and error prone. In addition, you will also have to update any pages where there is a register tag for the older libraries as well.  This would require you to redeploy any application that have this issue. 3) Use the Configured Assembly capabilities of .Net (aka: Assembly Bindings) to make any application that uses the older AJAX libraries to use the new AJAX libraries.  IMO, this is the easiest, quickest and least invasive way to fix the issue.  Below are the steps to implement this fix. Solution #3 Do the following steps on the IIS servers that the issue is occurring.  The 2 assemblies that need assemblies bindings created are: System.Web.Extension & System.Web.Extensions.Design 1) Go to Start - > All Program -> Administrative Tools -> Microsoft .NET Framework 2.0 Configuration. 2) Right click on "Configured Assemblies" to view list of configured assemblies. 3) Left Click on right pane to bring up menu and choose "Add". 4) Make sure "Choose and assembly from the assembly cache is checked" and click the "Choose Assembly" button. 5) Choose System.Web.Extension (does not matter what version). 6) Click the "Finish" button. 7) Binding Policy Tab      - Enter Requested Version = 1.0.61025.0      - Enter New Version = 3.5.0.0 8) Repeat steps 2-7 for the System.Web.Extensions.Design assembly. --------------------------------------------------------------------------------------------------------------------------------------------------------- Note: If "Microsoft .NET Framework 2.0 Configuration does not exist under Admin tools use mmc to access it (see below) 1) Start -> Run -> Enter MMC 2) File - > Add/Remove Snap-In then Click "Add" button 3) Choose ".Net 2.0 Configuration" then click "Add" button and then the "Close" Button. 4) On "Add/Remove Snapin" windows click the "OK" Button. 5) Expand the tree on the right and you can start following the directions above for adding the configured assemblies. ---------------------------------------------------------------------------------------------------------------------------------------------------------
