  - by Daryl Gill

  I'm Programming on a Windows Server 2008 and I wish to have a WebUI to interact with the domains active directory.

• Which SCM/VCS cope well with moving text between files?

  - by pfctdayelise

  We are having havoc with our project at work, because our VCS is doing some awful merging when we move information across files. The scenario is thus: You have lots of files that, say, contain information about terms from a dictionary, so you have a file for each letter of the alphabet. Users entering terms blindly follow the dictionary order, so they will put an entry like "kick the bucket" under B if that is where the dictionary happened to list it (or it might have been listed under both B, bucket and K, kick). Later, other users move the terms to their correct files. Lots of work is being done on the dictionary terms all the time. e.g. User A may have taken the B file and elaborated on the "kick the bucket" entry. User B took the B and K files, and moved the "kick the bucket" entry to the K file. Whichever order they end up getting committed in, the VCS will probably lose entries and not "figure out" that an entry has been moved. (These entries are later automatically converted to an SQL database. But they are kept in a "human friendly" form for working on them, with lots of comments, examples etc. So it is not acceptable to say "make your users enter SQL directly".) It is so bad that we have taken to almost manually merging these kinds of files now, because we can't trust our VCS. :( So what is the solution? I would love to hear that there is a VCS that could cope with this. Or a better merge algorithm? Or otherwise, maybe someone can suggest a better workflow or file arrangement to try and avoid this problem?

• Is it valid to use unsafe struct * as an opaque type instead of IntPtr in .NET Platform Invoke?

  - by David Jeske

  .NET Platform Invoke advocates declaring pointer types as IntPtr. For example, the following [DllImport("user32.dll")] static extern IntPtr SendMessage(IntPtr hWnd, UInt32 Msg, Int32 wParam, Int32 lParam); However, I find when interfacing with interesting native interfaces, that have many pointer types, flattening everything into IntPtr makes the code very hard to read and removes the typical typechecking that a compiler can do. I've been using a pattern where I declare an unsafe struct to be an opaque pointer type. I can store this pointer type in a managed object, and the compiler can typecheck it form me. For example: class Foo { unsafe struct FOO {}; // opaque type unsafe FOO *my_foo; class if { [DllImport("mydll")] extern static unsafe FOO* get_foo(); [DllImport("mydll")] extern static unsafe void do_something_foo(FOO *foo); } public unsafe Foo() { this.my_foo = if.get_foo(); } public unsafe do_something_foo() { if.do_something_foo(this.my_foo); } While this example may not seem different than using IntPtr, when there are several pointer types moving between managed and native code, using these opaque pointer types for typechecking is a godsend. I have not run into any trouble using this technique in practice. However, I also have not seen an examples of anyone using this technique, and I wonder why. Is there any reason that the above code is invalid in the eyes of the .NET runtime? My main question is about how the .NET GC system treats "unsafe FOO *my_foo". Is this pointer something the GC system is going to try to trace, or is it simply going to ignore it? My hope is that because the underlying type is a struct, and it's declared unsafe, that the GC would ignore it. However, I don't know for sure. Thoughts?

• UpdatePanel and ModalPopup Extender

  - by rs

  I have my form designed as <asp:Panel runat="server" Id="xyz"> <asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional"> <ContentTemplate> 'Gridview with edit/delete - opens detailsview(edit template) with data for editing </ContentTemplate> </asp:UpdatePanel> <asp:UpdatePanel ID="UpdatePanel2" runat="server" UpdateMode="Conditional"> <ContentTemplate> 'Hyperlink to open detailsview(insert template) for inserting records </ContentTemplate> </asp:UpdatePanel> </asp:Panel> <asp:Panel runat="server" Id="xyz1"> 'Ajax modal popup extender control </asp:Panel> It works perfectly when i click update, insert alternately, but when i click insert hyperlink (which is outside gridview) and close/cancel popup without any insert and then again click insert it doesn't call insert_onclick event. It works if i click some other button and click this button. What could be causing this issue and how can i solve it?

• How to give the menus associated with dojo's dijit.ComboBox different css from those of dijit.Menu

  - by sprugman

  When you use a dijit.ComboBox, the type ahead suggestions get implemented as a dijit.Menu. I've got a design which calls for the matched portion of the suggestion rows to be normal, and the unmatched portion to be bold. The structure that dojo creates is like this: <ul class="dijitReset dijitMenu"> <li role="option" class="dijitReset dijitMenuItem"> <span class="dijitComboBoxHighlightMatch">Ch</span>oice One </li> <li role="option" class="dijitReset dijitMenuItem"> <span class="dijitComboBoxHighlightMatch">Ch</span>oice Two </li> </ul> So I can target the matched part, but not the unmatched part. So my css needs to be something like: .dijitMenuItem { font-weight: bold; } .dijitMenuItem .dijitComboBoxHighlightMatch { font-weight: normal; } The problem is, if I do that, all menus will be bolded, and I don't want that. Just doing something like this: <select dojoType="dijit.form.ComboBox" class="foobar">[options]</select> puts the foobar class in the ComboBox, but the menu is an independent node not under that hierarchy. What's the easiest way to add a css class around the popup menu that the ComboBox generates?

• MySQL BinLog Statement Retrieval

  - by Jonathon

  I have seven 1G MySQL binlog files that I have to use to retrieve some "lost" information. I only need to get certain INSERT statements from the log (ex. where the statement starts with "INSERT INTO table SET field1="). If I just run a mysqlbinlog (even if per database and with using --short-form), I get a text file that is several hundred megabytes, which makes it almost impossible to then parse with any other program. Is there a way to just retrieve certain sql statements from the log? I don't need any of the ancillary information (timestamps, autoincrement #s, etc.). I just need a list of sql statements that match a certain string. Ideally, I would like to have a text file that just lists those sql statements, such as: INSERT INTO table SET field1='a'; INSERT INTO table SET field1='tommy'; INSERT INTO table SET field1='2'; I could get that by running mysqlbinlog to a text file and then parsing the results based upon a string, but the text file is way too big. It just times out any script I run and even makes it impossible to open in a text editor. Thanks for your help in advance.

• Can I perform some processing on the POST data before ASP.NET MVC UpdateModel happens?

  - by Domenic

  I would like to strip out non-numeric elements from the POST data before using UpdateModel to update the copy in the database. Is there a way to do this? // TODO: it appears I don't even use the parameter given at all, and all the magic // happens via UpdateModel and the "controller's current value provider"? [HttpPost] public ActionResult Index([Bind(Include="X1, X2")] Team model) // TODO: stupid magic strings { if (this.ModelState.IsValid) { TeamContainer context = new TeamContainer(); Team thisTeam = context.Teams.Single(t => t.TeamId == this.CurrentTeamId); // TODO HERE: apply StripWhitespace() to the data before using UpdateModel. // The data is currently somewhere in the "current value provider"? this.UpdateModel(thisTeam); context.SaveChanges(); this.RedirectToAction(c => c.Index()); } else { this.ModelState.AddModelError("", "Please enter two valid Xs."); } // If we got this far, something failed; redisplay the form. return this.View(model); } Sorry for the terseness, up all night working on this; hopefully my question is clear enough? Also sorry since this is kind of a newbie question that I might be able to get with a few hours of documentation-trawling, but I'm time-pressured... bleh.

• Multiplication of 2 positive numbers giving a negative result

  - by krandiash

  My program is an implementation of a bloom filter. However, when I'm storing my hash function results in the bit array, the function (of the form f(i) = (a*i + b) % m where a,b,i,m are all positive integers) is giving me a negative result. The problem seems to be in the calculation of a*i which is coming out to be negative. Ignore the print statements in the code; those were for debugging. Basically, the value of temp in this block of code is coming out to be negative and so I'm getting an ArrayOutOfBoundsException. m is the bit array length, z is the number of hash functions being used, S is the set of values which are members of this bloom filter and H stores the values of a and b for the hash functions f1, f2, ..., fz. public static int[] makeBitArray(int m, int z, ArrayList<Integer> S, int[] H) { int[] C = new int[m]; for (int i = 0; i < z; i++) { for (int q = 0; q < S.size() ; q++) { System.out.println(H[2*i]); int temp = S.get(q)*(H[2*i]); System.out.println(temp); System.out.println(S.get(q)); System.out.println(H[2*i + 1]); System.out.println(m); int t = ((H[2*i]*S.get(q)) + H[2*i + 1])%m; System.out.println(t); C[t] = 1; } } return C; } Any help is appreciated.

• Prompt User before browser close?

  - by JM4

  We have an administrative portal that our teachers constantly forget to download their latest PDF instructions before logging out and/or closing the browser window. I have looked around but can't find what I'm looking for. I want to accomplish the following goals: Goal 1 Before a user can close the browser window, they are prompted "Did you remember to download your form?" with two options, yes/no. If yes, close, if no, return to page. Goal 2 Before a user can click the 'logout' button, they are prompted with the same as above. My first pass at the very basic code (which does not work for browser close) is: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Untitled Document</title> <script type="text/javascript"> function init() { if(window.addEventListener) { window.addEventListener("beforeunload", unloadMess, false); } else if(window.onbeforeunload) { window.onbeforeunload = unloadMess; }; } function unloadMess() { var User_Message = "[Your user message here]" return User_Message; } </script> </head> <body onload="init();"> hello this is my site </body> </html> anybody ever come across a good solution?

• Jquery CheckBox Selection/Deselection optimally given X checkboxes

  - by Amitd

  Hi guys, I have suppose say 'X' check-boxes(any input elements) in a Form and "M" option selection indexes ("M" less than equal to "X"). then how do i select the "M" option indexes/values and deselect the rest of check-boxes optimally? i.e.Suppose I have 10 Checkboxes and 5 Option Indices(eg: 1,2,4,5,8) then i have to select checkboxes with given index . I could come up with the following code: HTML: <div id="Options"> <input id="choice_1" type="checkbox" name="choice_1" value="Option1"><label for="choice_1">Option1</label> <input id="choice_2" type="checkbox" name="choice_2" value="Option2"><label for="choice_2">Option2</label> <input id="choice_3" type="checkbox" name="choice_3" value="Option3"><label for="choice_3">Option3</label> .. ..till choice_10 </div> IN JS: //Have to select checkboxes with "Value" in choicesToSelect and give a selection //effect to its label var choicesToSelect={"Option1","Option9","Option3","Option4","Option2"}; selectHighlightCheckBoxes(choicesToSelect); function selectHighlightCheckBoxes(choices){ $.each( choices, function(intIndex, objValue) { //select based on id or value or some criteria var option = $("#Options :input[value=" + objValue + "]") ; if ($(option).is("input[type='radio']") || $(option).is("input[type='checkbox']")) { $(option).attr('checked', true); $(option).next('label:first').css({ 'border': '1px solid #FF0000', 'background-color': '#BEF781', 'font-weight': 'bolder' }); } else if ($(option).is("input[type='text']")) { $(option).css({ 'border': '1px solid #FF0000', 'background-color': '#BEF781', 'font-weight': 'bolder' }); } else { } } ); } But i want to also add effect to the rest (not in choicesToSelect array) also. (may be red color to those not in choiceToSelect) Can this be done in the one traversal/loop? Optimally? or Better way?

• Using Javascript to flip flop a textbox's readonly flag

  - by Velika

  I have a frame with several radio buttons where the user is supposed to select the "Category" that his Occupation falls into and then unconditionally also specify his occupation. If the user selects "Retired", the requirement is to prefill "Retired" in the "Specify Occupation" text box and to disable it to prevent it from being changed. The Specify Occupation text box should also no longer be a tab stop. If the user selects a radio button other than Retired the Specify Occupation text box should be enabled and once again in the normal tab sequence. Originally, I was setting and clearing the disabled property on the Specify occupation textbox, then I found out that, upon submitting the form, disabled fields are excluded from the submit and the REQUIRED validator on the Specify Occupation textbox was being raised because the textbox was being blanked out. What is the best way to solve this? My approach below was to mimic a disabled text box by setting/resetting the readonly attribute on the text box and changing the background color to make it appear disabled. (I suppose I should be changing the forecolor instead of teh background color). Nevertheless, my code to make the textbox readonly and to reset it doesn't appear to be working. function OccupationOnClick(sender) { debugger; var optOccupationRetired = document.getElementById("<%= optOccupationRetired.ClientId %>"); var txtSpecifyOccupation = document.getElementById("<%= txtSpecifyOccupation.ClientId %>"); var optOccupationOther = document.getElementById("<%= optOccupationOther.ClientId %>"); if (sender == optOccupationRetired) { txtSpecifyOccupation.value = "Retired" txtSpecifyOccupation.readonly = "readonly"; txtSpecifyOccupation.style.backgroundColor = "#E0E0E0"; txtSpecifyOccupation.tabIndex = -1; } else { if (txtSpecifyOccupation.value == "Retired") txtSpecifyOccupation.value = ""; txtSpecifyOccupation.style.backgroundColor = "#FFFFFF"; txtSpecifyOccupation.readonly = ""; txtSpecifyOccupation.tabIndex = 0; } } Can someone provide a suggest for the best way to handle this scenario and porovide a tweek to the code above to fix the setting/resetting on the readonly property?

• iPhone app rejection for using ICU (Unicode extensions)

  I received the following mail form Apple, considering my application: *Thank you for submitting your update to ??µ??es?a to the App Store.

• ASP.Net MVC vs ASP.Net for Complex workflows

  - by Grant Sutcliffe

  I have just become involved in migrating a series of complex workflows with InfoPath UIs to Web-based UIs. I am new to ASP.Net MVC but have started to evaluate it as the technology versus classic ASP.Net for the job. As is typical of most workflows, in each state there are a number of business rules that determine (a) who can view what content; (2) who can edit what content; (3) what the user action options might be (Edit; Reject; Approve), etc. In essence, there is a lot of logic that needs to be applied to each request before presenting the appropriate view. Being more experienced in ASP.Net, I know that presenting the form(s) as required can be easily achieved through code behind pages (enable / disable / hide fields). I have not seen how this can be achieved with ASP.Net MVC (but am realising that new thinking is required of me when working with MVC - ‘Give only the content on a particular View + limited user action options’). Therefore, if using ASP.Net MVC, it looks like I would need to create a lot of views. Much of the content in each view would be the same. Only field enabled status or buttons would differ in most instances for these views in each state. For example: Step01Initiate (‘Has Save’ button); Step01OriginatorView (has ‘Edit’ Button) ; Step01OriginatorEdit (has ‘Save’ button); Step01Review (has ‘Accept’ / ‘Reject’ buttons); Step01ReviewReject (for reviewer notes; has ‘Save’ / ‘Cancel’ buttons). With workflows of up to six states, this would result in a lot of views. I can see the advantages of choosing ASP.MVC (1) ‘thin’ Views in terms of content; and (2) with logic consolidation in Controllers and different Models. Am I thinking along the right lines in terms of applying the MVC – ‘plenty of views’; or is there a better way to achieve my goal (using ASP.Net MVC or classic ASP.Net)?

  I am trying to configure a custom layout class to Log4J as described in my previous post. The class uses java.util.regex.Matcher to identify potential credit card numbers in log messages. It works perfectly in unit tests (I can also programmatically configure a logger to use it and produce the expected output). However when I try to deploy it with our app in JBoss, I get the following error: --- MBEANS THAT ARE THE ROOT CAUSE OF THE PROBLEM --- ObjectName: jboss.web.deployment:war=MyWebApp-2010_02-SNAPSHOT.war,id=476602902 State: FAILED Reason: java.lang.LinkageError: java/util/regex/Matcher I couldn't even find any info on this form of the error - typically LinkageError seems to show up with a "loader constrain violation" message, like in here. Technical details: we use JBoss 4.2, Java 5, Log4J 1.2.12. We deploy our app in an .ear, which contains (among others) the above mentioned .war file, and the custom layout class in a separate jar file. We override the default settings in jboss-log4J.xml with our own log4j.properties located in a different folder, which is added to the classpath at startup, and is provided via Carbon. I can only guess: are two different Matcher class versions loaded from somewhere, or is Matcher loaded by two different classloaders when it is used from the jar and the war? What does this error message mean, and how can I fix it?

• Powershell - Splitting string into seperate components

  - by TheD

  I am writing a script which will basically do the following: Read from a text file some arguements: DriveLetter ThreeLetterCode ServerName VolumeLetter Integer Eg. W MSS SERVER01 C 1 These values happen to form a folder destination W:\MSS\, and a filename which works in the following naming convention: SERVERNAME_VOLUMELETTER_VOL-b00X-iYYY.spi - Where The X is the Integer above The value Y I need to work out later, as this happens to be the value of the incremental image (backups) and I need to work out the latest incremental. So at the moment -- Count lines in file, and loop for this many lines. $lines = Get-Content -Path PostBackupCheck-Textfile.txt | Measure-Object -Line for ($i=0; $i -le $lines.Lines; $i++) Within this loop I need to do a Get-Content to read off the line I am currently looking at i.e. line 0, line 1, line 2, as there will be multiple lines in the format I wrote at the beginning and split the line into an array, whereby each part of the file, as seen above naming convention, is in a[0], a[1], a[2]. etc The reason for this is because, I need to then sort the folder that contains these, find the latest file, by date, and take the _iXXX.spi part and place this into the array value a[X] so I then have a complete filename to mount. This value will replace iYYY.spi It's a little complex because I also have to make sure when I do a Get-ChildItem with -Include before I sort it all by date, I am only including the filename that matches the arguements fed to it from the text file : So, SERVER01_C_VOL-b001-iYYY.spi and not anything else. i.e. not SERVER01_D_VOL-b001-iYYY.spi Then take the iYYY value from the sort on the Get-ChildItem -Include and place that into the appropriate array item. I've literally no idea where to start, so any ideas are appreciated! Hopefully I've explained in enough detail. I have also placed the code on Pastebin: http://pastebin.com/vtFifTW6 Thanks!

• Prevent deferred creation of controls.

  - by Scott Chamberlain

  Here is a test framework to show what I am doing, just create a new project add a tabbed control, on tab 1 put a button on tab 2 put a check box (default names) and paste this code for its code public partial class Form1 : Form { private List<bool> boolList = new List<bool>(); BindingSource bs = new BindingSource(); public Form1() { InitializeComponent(); boolList.Add(false); bs.DataSource = boolList; checkBox1.DataBindings.Add("Checked", bs, ""); } bool updating = false; private void button1_Click(object sender, EventArgs e) { updating = true; boolList[0] = true; bs.ResetBindings(false); Application.DoEvents(); updating = false; } private void checkBox1_CheckedChanged(object sender, EventArgs e) { if (!updating) MessageBox.Show("CheckChanged fired outside of updating"); } } The issue is if you run the program and look at tab 2 then press the button on tab 1 the program works as expected, however if you press the button on tab 1 then look at tab 2 the event for the checkbox will not fire untill you look at tab 2. The reason for this is the controll on tab 2 is not in the "created" state, so its binding to change the checkbox from unchecked to checked does not happen until after the control has been "Created". checkbox1.CreateControl() does not do anything because according to MSDN CreateControl does not create a control handle if the control's Visible property is false. You can either call the CreateHandle method or access the Handle property to create the control's handle regardless of the control's visibility, but in this case, no window handles are created for the control's children. I tried getting the value of Handle(there is no CreateHandle for Button) but still the same result. Any suggestions other than have the program quickly flash all of my tabs that have data-bound check boxes when it first loads?

• What is the best software design to use in this scenario

  - by domdefelice

  I need to generate HTML snippets using jQuery. The creation of those snippets depends on some data. The data is stored server-side, in session (where PHP is used). At the moment I achieved this - retrieving the data from the server via AJAX in form of JSON - and building the snippets via specific javascript functions that read those data The problem is that the complexity of the data is getting bigger and hence the serialization into JSON is getting even more difficult since I can't do it automatically. I can't do it automatically because some information are sensible so I generate a "stripped" version to send to the client. I know it is difficult to understand without any code to read, but I am hoping this is a common scenario and would be glad for any tip, suggestion or even design-pattern you can give me. Should I store both a complete and a stripped data on the server and then use some library to automatically generate the JSON from the stripped data? But this also means I have to get the two data synchronized. Or maybe I could move the logic server-side, this way avoiding sending the data. But this means sending javascript code (since I rely on jQuery). Maybe not a good idea. Feel free to ask me more details if this is not clear. Thank you for any help

• mod_rewrite with question marks and ampersands (with PHP)

  - by Chris

  I have a PHP-based web app that I'm trying to apply Apache's mod_rewrite to. Original URLs are of the form: http://example.com/index.php?page=home&x=5 And I'd like to transform these into: http://example.com/home?x=5 Note that while rewriting the page name, I'm also effectively "moving" the question mark. When I try to do this, Apache happily performs this translation: RewriteRule ^/([a-z]+)\?(.+)$ /index.php?page=$1&$2 [NC,L] But it messes up the $_GET variables in PHP. For example, a call to http://example.com/home?x=88 yields only one $_GET variable (page => home). Where did x => 88 go? However, when I change my rule to use an ampersand rather than a question mark: RewriteRule ^/([a-z]+)&(.+)$ /index.php?page=$1&$2 [NC,L] a call like http://example.com/home&x=88 will work just as I'd expect it to (i.e. both the page and x $_GET variables are set appropriately). The difference is minimal I know, but I'd like my URL variables to "start" with a question mark, if it's possible. I'm sure this reflects my own misunderstanding of how mod_rewrite redirects interact with PHP, but it seems like I should be able to do this (one way or another). Thanks in advance! Cheers, -Chris

• Simple imeplementation of admin/staff panel?

  - by Michael Mao

  Hi all: A new project requires a simple panel(page) for admin and staff members that : Preferably will not use SSL or any digital ceritification stuff, a simple login from via http will just be fine. has basic authentication which allows only admin to login as admin, and any staff member as of the group "staff". Ideally, the "credentials(username-hashedpassword pair)" will be stored in MySQL. is simple to configure if there is a package, or the strategy is simple to code. somewhere (PHP session?) somehow (include a script at the beginning of each page to check user group before doing anything?), it will detect any invalid user attempt to access protected page and redirect him/her to the login form. while still keeps high quality in security, something I worry about the most. Frankly I am having little knowledge about Internet security, and how modern CMS such as WordPress/Joomla do with their implementation in this. I only have one thing in my mind that I need to use a salt to hash the password (SHA1?) to make sure any hacker gets the username and password pair across the net cannot use that to log into the system. And that is what the client wants to make sure. But I really not sure where to start, any ideas? Thanks a lot in advance.

• Read cookies with JavaScript

  - by Etienne

  I know how to write cookies in JavaScript //Create the cookies document.cookie = "Name=" + Name + ";expires=Friday, 31-Dec-2011 12:00:00 GMT; path=/"; document.cookie = "Surname=" + Surname + ";expires=Friday, 31-Dec-2011 12:00:00 GMT; path=/"; document.cookie = "Number=" + Number + ";expires=Friday, 31-Dec-2011 12:00:00 GMT; path=/"; document.cookie = "Email=" + Email + ";expires=Friday, 31-Dec-2011 12:00:00 GMT; path=/"; document.cookie = "Country=" + Country + ";expires=Friday, 31-Dec-2011 12:00:00 GMT; path=/"; document.cookie = "Company=" + Company + ";expires=Friday, 31-Dec-2011 12:00:00 GMT; path=/"; document.cookie = "Title=" + Job + ";expires=Friday, 31-Dec-2011 12:00:00 GMT; path=/"; But how can I read each one of them in JavaScript because I want to populate the text boxes next time the user come to the form? I have tried this but it does not work............ var cookieName = ReadCookie("Name"); document.getElementById('txtName').value = cookieName; Thanks in advanced!!
