  • Regex Problem in PHP

    - by Chris
    I'm attempting to utilize the following Regex pattern: $regex = '/Name: [a-zA-Z ]*] [0-9]/'; When testing it in Rubular, it works fine, but when using PHP the expression never returns true, even when it should. Incidentally, if I remove the "[0-9]" part, it works fine. Is there some difference in PHP's regex syntax that I'm overlooking? Edit: I'm looking for the characters "Name:" then a name containing any number of letters or spaces, then a "]", then a space, then a single number. So "Name: Chris] 5" would return true and "Name: Chris] [lorem ipsum]" should return false. I also tried escaping the second bracket "\[" but this did not fix the problem.

  • Need to skip newline char (\n) from input file

    - by igor
    I am reading in a file into an array. It is reading each char, the problem arises in that it also reads a newline in the text file. This is a sudoku board, here is my code for reading in the char: bool loadBoard(Square board[BOARD_SIZE][BOARD_SIZE]) { ifstream ins; if(openFile(ins)){ char c; while(!ins.eof()){ for (int index1 = 0; index1 < BOARD_SIZE; index1++) for (int index2 = 0; index2 < BOARD_SIZE; index2++){ c=ins.get(); if(isdigit(c)){ board[index1][index2].number=(int)(c-'0'); board[index1][index2].permanent=true; } } } return true;} return false; } like i said, it reads the file, displays on screen, just not in correct order when it encounters the \n

  • MVC architectural question - Where should payment processing go?

    - by Keltex
    This question is related to my ASP.NET MVC 2 development, but it could apply to any MVC environment and a question of where the logic should go. So let's say I have a controller that takes an online payment such as a shopping cart application. And I have the method that accepts the customers' credit card information: public class CartController : Controller CartRepository cartRepository = new CartRepository() [HttpPost] public ActionResult Payment(PaymentViewModel rec) { if(!ModelState.IsValid) { return View(rec); } // process payment here return RedirectToAction("Receipt"); } At the comment process payment here should the payment processing be handled: In the controller? By the repository? Someplace else?

  • How to implement List, Set, and Map in null free design?

    - by Pyrolistical
    Its great when you can return a null/empty object in most cases to avoid nulls, but what about Collection like objects? In Java, Map returns null if key in get(key) is not found in the map. The best way I can think of to avoid nulls in this situation is to return an Entry<T> object, which is either the EmptyEntry<T>, or contains the value T. Sure we avoid the null, but now you can have a class cast exception if you don't check if its an EmptyEntry<T>. Is there a better way to avoid nulls in Map's get(K)? And for argument sake, let's say this language don't even have null, so don't say just use nulls.

    - by Richard

I also have another redirect page with content="3; url=http://www.domain.nl/index/index?rcgo=logout" /> and that works fine How can I get the javascript to work because I have three submit buttons that need to be set to different get variables.

  • Cannot populate form with ajax and populate jquery plugin

    - by Azriel_
    I'm trying to populate a form with jquery's populate plugin, but using $.ajax The idea is to retrieve data from my database according to the id in the links (ex of link: get_result_edit.php?id=34), reformulate it to json, return it to my page and fill up the form up with the populate plugin. But somehow i cannot get it to work. Any ideas: here's the code: $('a').click(function(){ $('#updatediv').hide('slow'); $.ajax({ type: "GET", url: "get_result_edit.php", success: function(data) { var $response=$(data); $('#form1').populate($response); } }); $('#updatediv').fadeIn('slow'); return false; whilst the php file states as follow: <?php $conn = new mysqli('localhost', 'XXXX', 'XXXXX', 'XXXXX'); @$query = 'Select * FROM news WHERE id ="'.$_GET['id'].'"'; $stmt = $conn->query($query) or die ($mysql->error()); if ($stmt) { $results = $stmt->fetch_object(); // get database data $json = json_encode($results); // convert to JSON format echo $json; } ?> Now first thing is that the mysql returns a null in this way: is there something wrong with he declaration of the sql statement in the $_GET part? Second is that even if i put a specific record to bring up, populate doesn't populate. Update: I changed the populate library with the one called "PHP jQuery helper functions" and the difference is that finally it says something. finally i get an error saying NO SUCH ELEMENT AS i wen into the library to have a look and up comes the following function function populateFormElement(form, name, value) { // check that the named element exists in the form var name = name; // handle non-php naming var element = form[name]; if(element == undefined) { debug('No such element as ' + name); return false; } // debug options if(options.debug) { _populate.elements.push(element); } } Now looking at it one can see that it should print out also the name, but its not printing it out. so i'm guessing that retrieving the name form the json is not working correctly. Link is at http://www.ocdmonline.org/michael/edit%5Fnews.php with username: Testing and pass:test123 Any ideas?

  • Selecting the most common value from relation - SQL statement

    - by Ronnie
    I have a table within my database that has many records, some records share the same value for one of the columns. e.g. | id | name | software | ______________________________ | 1 | john | photoshop | | 2 | paul | photoshop | | 3 | gary | textmate | | 4 | ade | fireworks | | 5 | fred | textmate | | 6 | bob | photoshop | I would like to return the value of the most common occurring piece of software, by using an SQL statement. So in the example above the required SQL statement would return 'photoshop' as it occurs more than any other piece of software. Is this possible? Thank you for your time.

  • Unbox an Object to Its Type

    - by Ngu Soon Hui
    Hello, is there anyway to unbox an object to its real type? Basically I am given an ArrayList, the array list are actually a list of int or double, or maybe other types ( it can be either, but it is either all int or double, no mix). Now, I will have to return a List<double> or List<int> or other list, depending on what is the real type. public List<T> ConvertToList<T>(ArrayList arr) { var list1 = new List<T>(); foreach(var obj in arr) { // how to do the conversion? var objT = ?? list1.Add(objT); } return list1; } Any idea?

  • adding tabs to tabcontrol from inside usercontrol

    - by Jakob
    How can I add tabs to a tabcontrol that exists in one usercontrol from another usercontrol that is contained within a tab itself?? Can I do it without passing in the tabcontrol as a parameter in the constructor, perhaps via some static global method? I've tried public static ObservableTabCollection FindCollectionFromUC(this DependencyObject depObject) { bool loop = true; var parent = (VisualTreeHelper.GetParent(depObject) as FrameworkElement); while (loop) { if (parent.GetType() is TabControl) { loop = false; return ((ObservableTabCollection)((TabControl)parent).ItemsSource); } } return null; } but this is just an infinite loop

  • object won't die (still references to it that I can't find)

    - by user288558
    I'm using parallel-python and start a new job server in a function. after the functions ends it still exists even though I didn't return it out of the function (I used weakref to test this). I guess there's still some references to this object somewhere. My two theories: It starts threads and it logs to root logger. My questions: can I somehow findout in which namespace there is still a reference to this object. I have the weakref reference. Does anyone know how to detach a logger? What other debug suggestions do people have? here is my testcode: def pptester(): js=pp.Server(ppservers=nodes) js.set_ncpus(0) fh=file('tmp.tmp.tmp','w') tmp=[] for i in range(200): tmp.append(js.submit(ppworktest,(),(),('os','subprocess'))) js.print_stats() return weakref.ref(js) thanks in advance Wolfgang

  • How to use ResourceManager in a "website" mode ?

    - by Erick
    I am trying here to do a manual translation for the application I am working with. (There is already a working LocalizationModule but it's working dodgy, so I can't use <asp:Localize /> tags. Normally with ResourceManager you are supposed to be using it as Namespace.Folder.Resourcename (in an application). Currently I am translating an existing asp.net "website" (not web application so no namespace here....). The resources are located into a folder name "Locales/resources" which contains "fr-ca.resx" and "en-us.resx". So I used a code with something like this : public static string T(string search) { System.Resources.ResourceManager resMan = new System.Resources.ResourceManager( "Locales", System.Reflection.Assembly.GetExecutingAssembly(), null ); var text = resMan.GetString(search, System.Threading.Thread.CurrentThread.CurrentCulture); if (text == null) return "null"; else if (text == string.Empty) return "empty"; else return text; } and inside the page I have something like this <%= Locale.T("T_HOME") %> When I refresh I have this : Could not find any resources appropriate for the specified culture or the neutral culture. Make sure "Locales.resources" was correctly embedded or linked into assembly "App_Code.9yopn1f7" at compile time, or that all the satellite assemblies required are loadable and fully signed. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

  • Zend Framework: Flash Messenger, add a message from the model

    - by Dan
    Any idea on how best to add a message to flash messenger from the model? As FlashMessenger is an action helper, this seems not to be possible, so the obvious solution is to create an internal message object in the model, and return that to the controller from where you can use addMessage(). But if you want to return something else as well, this falls down. Another idea is an additional session namespace for these internal messages, which is then merged in with the Flash Messenger namespace messages at output time? Anyone have any thoughts or experience on this? Cheers.

  • Custom UITableviewcell shows "fatal error: Can't unwrap Optional.None" issue in swift

    - by user1656286
    I need to load a custom cell in a UITableView. I created a custom subclass of UITableViewCell named "CustomTableViewCell". I have added a UITabelViewCell to the tableview (using drag and drop) as shown in figure. Then in file inspector I set the class of that UITabelViewCell to be "CustomTableViewCell". Here is my code: class ViewController: UIViewController,UITableViewDelegate,UITableViewDataSource { @IBOutlet var tableView : UITableView var items = String[]() override func viewDidLoad() { super.viewDidLoad() items = ["Hi","Hello","How"] self.tableView.registerClass(CustomTableViewCell.self, forCellReuseIdentifier: "CusTomCell") // Do any additional setup after loading the view, typically from a nib. } func tableView(tableView: UITableView!, numberOfRowsInSection section: Int) -> Int{ return items.count } func tableView(tableView: UITableView!, cellForRowAtIndexPath indexPath: NSIndexPath!) -> UITableViewCell!{ var cell:CustomTableViewCell = self.tableView.dequeueReusableCellWithIdentifier("CusTomCell") as CustomTableViewCell cell.labelTitle.text = items[indexPath.row] return cell; } override func didReceiveMemoryWarning() { super.didReceiveMemoryWarning() // Dispose of any resources that can be recreated. } } When I run my code, I get the following error: "fatal error: Can't unwrap Optional.None" as seen in the image.

  • How to Create MySQL Query to Find Related Posts from Multiple Tables?

    - by Robert Samuel White
    This is a complicated situation (for me) that I'm hopeful someone on here can help me with. I've done plenty of searching for a solution and have not been able to locate one. This is essentially my situation... (I've trimmed it down because if someone can help me to create this query I can take it from there.) TABLE articles (article_id, article_title) TABLE articles_tags (row_id, article_id, tag_id) TABLE article_categories (row_id, article_id, category_id) All of the tables have article_id in common. I know what all of the tag_id and category_id rows are. What I want to do is return a list of all the articles that article_tags and article_categories MAY have in common, ordered by the number of common entries. For example: article1 - tags: tag1, tag2, tag3 - categories: cat1, cat2 article2 - tags: tag2 - categories: cat1, cat2 article3 - tags: tag1, tag3 - categories: cat1 So if my article had "tag1" and "cat1 and cat2" it should return the articles in this order: article1 (tag1, cat1 and cat2 in common) article3 (tag1, cat1 in common) article2 (cat1 in common) Any help would genuinely be appreciated! Thank you!

  • Create a Python User() class that both creates new users and modifies existing users

    - by ensnare
    I'm trying to figure out the best way to create a class that can modify and create new users all in one. This is what I'm thinking: class User(object): def __init__(self,user_id): if user_id == -1 self.new_user = True else: self.new_user = False #fetch all records from db about user_id self._populateUser() def commit(self): if self.new_user: #Do INSERTs else: #Do UPDATEs def delete(self): if self.new_user == False: return False #Delete user code here def _populate(self): #Query self.user_id from database and #set all instance variables, e.g. #self.name = row['name'] def getFullName(self): return self.name #Create a new user >>u = User() >>u.name = 'Jason Martinez' >>u.password = 'linebreak' >>u.commit() >>print u.getFullName() >>Jason Martinez #Update existing user >>u = User(43) >>u.name = 'New Name Here' >>u.commit() >>print u.getFullName() >>New Name Here Is this a logical and clean way to do this? Is there a better way? Thanks.

  • Extract item in a list if Contains returns true

    - by Matt
    I have two lists A and B, at the beginning of my program, they are both filled with information from a database (List A = List B). My program runs, List A is used and modified, List B is left alone. After a while I reload List B with new information from the database, and then do a check with that against List A. foreach (CPlayer player in ListA) if (ListB.Contains(player)) ----- Firstly, the object player is created from a class, its main identifier is player.Name. If the Name is the same, but the other variables are different, would the .Contains still return true? Class CPlayer( public CPlayer (string name) _Name = name At the ---- I need to use the item from ListB that causes the .Contains to return true, how do I do that?

  • Ajax method within a added method in jQuery validator

    - by nikospkrk
    Hi, I'm kind of stuck with this pretty simple (I'm sure) jQuery/Javascript issue. Here's the code : jQuery.validator.addMethod("emailExists", function(value, element, param) { var email = value || ''; var valid = 0; $.ajax({ type: "POST", url: param, data: "email=" + email, success: function(msg) { if (msg != '' && msg) { valid = 0; } else { valid = 1; } } }); return valid; }, "* Email address already registered, please login."); This function is called where a user type his email address in a registration form, and everything seems to work perfectly, except that my valid variable returned isn't updated, whereas when I use an alert box it is properly done! It looks like it return the value before the AJAX is done, any idea? Cheers, Nicolas.

  • Scoping inside Javascript anonymous functions

    - by DCD
    I am trying to make a function return data from an ajax call that I can then use. The issue is the function itself is called by many objects, e.g.: function ajax_submit (obj) { var id = $(obj).attr('id'); var message = escape ($("#"+id+" .s_post").val ()); var submit_string = "action=post_message&message="+message; $.ajax({ type: "POST", url: document.location, data: submit_string, success: function(html, obj) { alert (html); } }); return false; } Which means that inside the anonymous 'success' function I have no way of knowing what the calling obj (or id) actually are. The only way I can think of doing it is to attach id to document but that just seems a bit too crude. Is there another way of doing this?

  • How to get Alfresco login ticket without user password, but with impersonating user with user principal name (UPN)

    - by dok
    I'm writing a DLL that has function for getting Alfresco login ticket without using user password, using only a user principal name (UPN). I’m calling alfresco REST API service /wcservice. I use NTLM in Alfresco. I’m impersonating users using WindowsIdentity constructor as explained here http://msdn.microsoft.com/en-us/library/ms998351.aspx#paght000023_impersonatingbyusingwindowsidentity. I checked and user is properly impersonated (I checked WindowsIdentity.GetCurrent().Name property). After impersonating a user, I try to make HttpWebRequest and set its credentials with CredentialsCache.DefaultNetworkCredentials. I get the error: The remote server returned an error: (401) Unauthorized. at System.Net.HttpWebRequest.GetResponse() When I use new NetworkCredential("username", "P@ssw0rd") to set request credentials, I get Alfresco login ticket (HttpStatusCode.OK, 200). Is there any way that I can get Alfresco login ticket without user password? Here is the code that I'm using: private string GetTicket(string UPN) { WindowsIdentity identity = new WindowsIdentity(UPN); WindowsImpersonationContext context = null; try { context = identity.Impersonate(); MakeWebRequest(); } catch (Exception e) { return e.Message + Environment.NewLine + e.StackTrace; } finally { if (context != null) { context.Undo(); } } } private string MakeWebRequest() { string URI = "http://alfrescoserver/alfresco/wcservice/mg/util/login"; HttpWebRequest request = WebRequest.Create(URI) as HttpWebRequest; request.CookieContainer = new CookieContainer(1); //request.Credentials = new NetworkCredential("username", "p@ssw0rd"); // It works with this request.Credentials = CredentialCache.DefaultNetworkCredentials; // It doesn’t work with this //request.Credentials = CredentialCache.DefaultCredentials; // It doesn’t work with this either try { using (HttpWebResponse response = request.GetResponse() as HttpWebResponse) { StreamReader sr = new StreamReader(response.GetResponseStream()); return sr.ReadToEnd(); } } catch (Exception e) { return (e.Message + Environment.NewLine + e.StackTrace); } } Here are records from Alfresco stdout.log (if it helps in any way): 17:18:04,550 DEBUG [app.servlet.NTLMAuthenticationFilter] Processing request: /alfresco/wcservice/mg/util/login SID:7453F7BD4FD2E6A61AD40A31A37733A5 17:18:04,550 DEBUG [web.scripts.DeclarativeRegistry] Web Script index lookup for uri /mg/util/login took 0.526239ms 17:18:04,550 DEBUG [app.servlet.NTLMAuthenticationFilter] New NTLM auth request from 10.**.**.** (10.**.**.**:1229) 17:18:04,566 DEBUG [app.servlet.NTLMAuthenticationFilter] Processing request: /alfresco/wcservice/mg/util/login SID:7453F7BD4FD2E6A61AD40A31A37733A5 17:18:04,566 DEBUG [web.scripts.DeclarativeRegistry] Web Script index lookup for uri /mg/util/login took 0.400909ms 17:18:04,566 DEBUG [app.servlet.NTLMAuthenticationFilter] Received type1 [Type1:0xe20882b7,Domain:<NotSet>,Wks:<NotSet>] 17:18:04,566 DEBUG [app.servlet.NTLMAuthenticationFilter] Client domain null 17:18:04,675 DEBUG [app.servlet.NTLMAuthenticationFilter] Sending NTLM type2 to client - [Type2:0x80000283,Target:AlfrescoServerA,Ch:197e2631cc3f9e0a]

  • How do I create an instance of this class in Android?

    I was wondering if it is possible to create an instance of this class (from the link, which creates a listview) from another class so that I can call on either lazyadapter.java or customizedlistview.java (not sure which one) to inflate that same listview.

  • Paging enormous tables on DB2

    - by grenade
    We have a view that, without constraints, will return 90 million rows and a reporting application that needs to display paged datasets of that view. We're using nhibernate and recently noticed that its paging mechanism looks like this: select * from (select rownumber() over() as rownum, this_.COL1 as COL1_20_0_, this_.COL2 as COL2_20_0_ FROM SomeSchema.SomeView this_ WHERE this_.COL1 = 'SomeValue') as tempresult where rownum between 10 and 20 The query brings the db server to its knees. I think what's happening is that the nested query is assigning a row number to every row satisfied by the where clause before selecting the subset (rows 10 - 20). Since the nested query will return a lot of rows, the mechanism is not very efficient. I've seen lots of tips and tricks for doing this efficiently on other SQL platforms but I'm struggling to find a DB2 solution. In fact an article on IBM's own site recommends the approach that nhibernate has taken. Is there a better way?

It does populate the drop down menu like it is supposed to it just does not seem to catch the data on the next page. Here is what I have: removeMain.php <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title></title> </head> <form action="remove.php" method="post"> <?php $link = mysql_connect('********', '********', '*********'); if (!$link){ die('Could not connect: ' . mysql_error()); } mysql_select_db("********", $link); $res = mysql_query("SELECT * FROM cardLists order by cardID") or die(mysql_error()); echo "<select name = CardID>"; while($row=mysql_fetch_assoc($res)) { echo "<option value=$row[ID]>$row[cardID]</a></option>"; } echo "</select>"; ?> Amount to Remove: <input type="text" name="Remove" /> <input type="submit" /> </form> <body> </body> </html> remove.php <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title></title> </head> <body> <?php $link = mysql_connect('*********', '*********', '*********'); if (!$link){ die('Could not connect: ' . mysql_error()); } mysql_select_db("***********y", $link); $query = sprintf("UPDATE cardLists SET AmountLeft = AmountLeft - %s WHERE cardID = '%s'", mysql_real_escape_string($_POST["Remove"]), mysql_real_escape_string($_POST["CardID"])); mysql_query($query); mysql_close($link); ?> <br /> <a href="removeMain.php"> <input type="submit" name="return" id="return" value="Update More" /></a> <a href="index.php"> <input type="submit" name="main" id="main" value="Return To Main" /></a> </body> </html>

  • getting date from JQueryUI Datepicker

    - by Shree

I want this function for validation of date ranges in JQueryUI daterangepicker which currently it is not supporting.
