• form data posted using linq-to-sql not showing until I refresh the page

  - by PeteShack

  I have an asp.net mvc app with a form. When you submit the form, it adds records to the sql database with linq-to-sql. After adding the records, the controller displays the form again, and should show those new values on the form. But, when it displays the form, the values are blank, until you refresh the page. While tracing through the code, I can see the records being added to the database when they are submitted, but the view doesnt display them, unless I refresh. The view is not the problem, it just displays the view model, which is missing the new records immediately after the post. I know this is kind of vague, but wasnt sure what parts of code to include here. Could this have something to do with data context life cycle? Basically, there is a data context created when the form is posted, then a different data context is created in the method that displays the form. Any suggestions on what might be causing this?

• CodeIgniter won't run in a subdirectory

  - by Tim Piele

  I have a CodeIgniter install running in our root web directory that I copied into a subdirectory called /dev... I edited the config/config.php file to reflect the change so it is now like this: $config['base_url'] = 'http://mysite.com/dev'; $config['sbase_url'] = 'https://mysite.com/dev'; $config['default_email'] = '[email protected]'; $config['site_url'] = 'http://mysite.com/dev'; This is my .htaccess file: <IfModule mod_rewrite.c> RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ index.php/$1 [L] </IfModule> When I hover over any links on the site they are correct, for example the contact us page link reads www.mysite.com/dev/contact but when I click any of the links I get a 404 error... Is there something common I am missing?

• What are the advantages of squashing assignment and error checking in one line?

  - by avakar

  This question is inspired by this question, which features the following code snippet. int s; if((s = foo()) == ERROR) print_error(); I find this style hard to read and prone to error (as the original question demonstrates -- it was prompted by missing parentheses around the assignment). I would instead write the following, which is actually shorter in terms of characters. int s = foo(); if(s == ERROR) print_error(); This is not the first time I've seen this idiom though, and I'm guessing there are reasons (perhaps historical) for it being so often used. What are those reasons?

  - by mysticfalls

  I would like to ask regarding this error... Error 49 at line 5, column 6 bad bind variable 'S_ORD.payment_type' Here is the code: DECLARE N NUMBER; v_credit S_CUSTOMER.credit_rating%type; BEGIN IF :S_ORD.payment_type = 'CREDIT' THEN SELECT credit_rating INTO v_credit FROM S_CUSTOMER WHERE :S_ORD.customer_id = id; IF v_credit NOT IN ('GOOD', 'EXCELLENT') THEN :S_ORD.payment_type:= 'CASH'; n:=SHOW_ALERT('Payment_Type_Alert'); END IF; END IF; END; I'm new to oracle forms so I'm not sure if I have a missing setup or anything. S_ORD table exist and has a column payment_type, which consists of 'CREDIT' and 'CASH' value. Thank you.

• JavaScript prototype(ing) question

  - by OneNerd

  Trying to grasp Prototyping in Javascript. Trying to create my own namespace to extend the String object in JavaScript. Here is what I have so far (a snippet): var ns { alert: function() { alert (this); } } String.prototype.$ns = ns; As you can see, I am trying to place what will be a series of functions into the ns namespace. So I can execute a command like this: "hello world".$ns.alert(); But the problem is, the this doesn't seem to reference the text being sent (in this case, "hello world"). What I get is an alert box with the following: [object Object] Not having a full grasp of the object-oriented nature of JavaScript, I am at a loss, but I am guessing I am missing something simple. Does anyone know how to achieve this? Thanks -

• Receiving integers, but also want to test for char.

  - by Wayne Haworth

  Say I am looking to receive a series of numeric values and read them into an int, but I also want to test if the user hit key 'x'. I am sure I am missing something obvious, and have tried a few things but seem to be stuck. This is what I have so far... cout << endl << "Enter key (or 'x' to exit): "; cin key; if (key == 'x') { cout << "exiting";} // continue on...

• Deleted nib still displayed when controller is pushed

  - by yahuie

  I have an application with a UINavcontroller under a tab bar controller. To create the navigation model I want, I push a container UIView object onto the stack to manage additional views(Thanks Frank). When I created the container class, an associated nib file was created along with it. I at first used that nib file, but it turned out it was better not to. So I deleted the nib (and selected 'also move to trash'). The problem is that it still shows up when I push its view controller onto the stack. I have tried emptying the cache in xcode and restarting xcode. What am I missing?

• Why does this MSDN example for Func<> delegate have a superfluous Select() call?

  - by Dan

  The MSDN gives this code example in the article on the Func Generic Delegate: Func<String, int, bool> predicate = ( str, index) => str.Length == index; String[] words = { "orange", "apple", "Article", "elephant", "star", "and" }; IEnumerable<String> aWords = words.Where(predicate).Select(str => str); foreach (String word in aWords) Console.WriteLine(word); I understand what all this is doing. What I don't understand is the Select(str => str) bit. Surely that's not needed? If you leave it out and just have IEnumerable<String> aWords = words.Where(predicate); then you still get an IEnumerable back that contains the same results, and the code prints the same thing. Am I missing something, or is the example misleading?

• Why use a "do while" loop?

  - by Stanni

  Hi, I've never understood why using a do while loops is necessary. I understand what they do, Which is to execute the code that the while loop contains without checking if the condition is true first. But isn't the below code: do{ document.write("ok"); } while(x == "10"){ document.write("ok"); } The exact same as: document.write("ok"); while(x == "10"){ document.write("ok"); } Maybe I'm being very stupid and missing something obvious out but I don't see the benefit of using do while over my above example.

• Sorting a listview (Win32/C++)

  - by Zenox

  I'm trying to sort a listview when the user clicks on the column header. I am catching the LVN_COLUMNCLICK notification like so: case LVN_COLUMNCLICK: { NMLISTVIEW* pListView = (NMLISTVIEW*)lParam; BOOL test = ListView_SortItems ( m_hDuplicateObjectsList, ListViewCompareProc, pListView->iSubItem ); break; } However it seems to fail. My test variable is FALSE and my ListViewCompareProc never gets hit (it has a simple return 1 while I am trying to hit a debug point inside of it). Is there something I am missing for sorting a listview?

• Can I find out what WCF methods are supported on the endpoint before calling it?

  - by alord1689

  I have a versioning issue with a WCF service contract in which one of the many endpoints which are called for the operation is missing one method from the contract. My question is, how can I make sure the command is available on the client before attempting to call it? I tried: foreach (var od in proxy.Endpoint.Contract.Operations) { if (od.Name == "MyMethodName") { hasMethod = true; break; } } Unfortunately, this is using the contract from the calling app and does not actually describe the implementations on the endpoint itself. As a result, it returns true even though the endpoint has failed to implement the command.

• Conditional Branching Issues

  - by Zack

  Here is the code: def main_menu print_main_menu user_selected = gets.chomp if user_selected.downcase == "no" main_menu elsif user_selected == "1" || "2" || "3" || "4" || "5" || "6" || "7" user_selected = user_selected.to_i call_option(user_selected) else main_menu end end This code uses calls to allow a user to make a selection from a main menu. Depending on the input, be it a certain number, a certain word, or something else, the respective method is called (in the case of a valid input) or the main menu is printed again (in the case of an invalid input or "no"). My questions are twofold. 1) Is there an efficient way to get rid of the literal string error that appears as a result of this redundant or statement on the elsif line? (the code itself works fine, but this error appears and is frustrating). 2) When an alternate/unspecified input is made by the user, the else branch doesn't execute and main_method doesn't start over. I have no idea why this is happening. Is there something I'm missing here? Thanks

• Grails searchable plugin with hasMany

  - by user2624442

  I am using grails searchable plugin to search my domain classes. However, I cannot yet search by my hasMany (skills and interests) fields even though they are of the simple type String. This is my domain class: class EmpactUser { static searchable = [except: ['dateCreated','password','enabled','accountExpired','accountLocked','passwordExpired']] String username String password boolean enabled = true boolean accountExpired boolean accountLocked boolean passwordExpired String email String firstName String lastName String address String phoneNumber String description byte[] avatar byte[] resume Date dateCreated static hasMany = [ skills : String, interests : String, // each user has the ability to list many skills and interests so that they can be matched with a project. ] static constraints = { username blank: false, unique: true password blank: false email email: true, blank: false firstName blank: false lastName blank: false description nullable: true address nullable: true avatar nullable: true, maxSize: 1024 * 1024 * 10 resume nullable: true, maxSize: 1024 * 1024 * 10 phoneNumber nullable: true, matches: "/[(][+]d{3}[)]d+/", maxSize: 30 } } This is the code I am using to search: def empactUserList = EmpactUser.search( searchQuery, [reload: false, result: "every", defaultOperator: "or"]) Am I missing something? Thanks, Alan.

• Prolem with if function

• Good Notification Plugin For Jquery?

  - by chobo2

  Hi I am looking at pines notify(http://pines.sourceforge.net/pnotify/) and it looks good but it seems to have little actual documentation so I am wondering is there anything more established and worked on out there? Like I don't want to spend time trying to figure out how to use pines and then find out it is missing some feature that I needed a few months later that I needed to change to a different plugin. This happened to me with tablesorter 2.0 I was using it then I needed the filtering but theirs kinda sucked so I found datatables what had such a bigger api and developed more. So I am wondering if there is something like datatables(in terms of development and features) just for notifications instead.

• Entity Framework 5 not updating navigation properties in both entities

  - by Taylor

  I have updated a project to use the new Entity framework shipped with VS2012, however I have run into some of my code throwing exceptions. In the VS10 version of EF I was able to create or modify and Entity and use its navigation properties before calling SaveChanges() For example: A Navigation property of a client having a collection of Invoices. Client c = new Client(); Invoice I = new Invoice(); c.Invoices.Add(I); I would then be able to use Invoice.Client somewhere in my code before actually saving it without issue. Now Invoice.Client == null. Similarly in setting I.Client = C, I does not show up under C.Invoices What am I missing here or is this just simply how EF5 is?

• Wordpress: Issues trying to display all comments in one page

  - by KeyStroke

  Hi, I'm trying to modify my wordpress theme (inove) to display all comments in the same page instead of 50 comments per page. I opened the comments.php file, commented out calls to paginate_comments_links() and and set the wp_list_comments() as follows: wp_list_comments('type=comment&callback=custom_comments&per_page=100&page=1'); The problem is, whenever someone posts a comments, the comment form appends '/comment-page-2/' to the URL after submitting the comment, even though I've specified that all comments to be displayed on the same page. Any idea what I could be missing? Appreciate your help

• compare two characters based on subset

  - by schultem

  I have a simple dataframe with two columns: df <- data.frame(x = c(1,1,2,2,3), y = c(rep(1:2,2),1), target = c('a','a','a','b','a')) I would like to compare the strings in the target column (find out whether they are equal or not, i.e., TRUE or FALSE) within every level of x (same number for x). First I would like to compare lines 1 and 2, then 3 and 4 ... My problem is that I am missing some comparisons, for example, line 5 has only one case instead of two - so it should turn out to be FALSE. Variable y indicates the first and second case within x. I played around with ddply doing something like: ddply(df, .(x), summarise, ifelse(as.character(df[df$y == '1',]$target), as.character(df[df$y == '2',]$target),0,1)) which is ugly ... and does not work ... Any insights how I could achieve this comparison? Thanks

• Mod_rewrite trouble: Want to direct from ?= to a flat link, nothing seems to work.

  - by Davezatch

  I have a site that currently serves results as example.com/index.php?show=foo and I'd like it to read example.com/show/foo. My understanding is this would make them visible to search engine robots, and it seems a much simpler way to do this than to create a couple hundred html files... I've tried the following .htaccess code: Options +FollowSymLinks RewriteEngine on RewriteRule ^show/(.*)$ index.php?show=$1 [NC,L] No dice. Also tried this, which I found on another stack overflow question: <IfModule mod_rewrite.c> RewriteEngine On RewriteBase / RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^([0-9A-Za-z]+)/?$ /index.php?show=$1 [L] </IfModule> Any ideas on what I'm missing here?

• PHP: reusing database class

  - by citricsquid

  Hi, I built a class that allows me to do: $db->query($query); and it works perfectly, although if I want to do: $db->query($query); while($row = $db->fetch_assoc()){ $db->query($anotherquery); echo $db->result(); } it "breaks" the class. I don't want to constantly have to redeclare my class (eg: $seconddb = new database()), is there a way to get around this? I want to be able to reuse $db within $db, without overwriting the "outside" db. currently I'm create an array of data (from db-fetch_assoc() then doing a foreach and then doing the db call inside that: $db->query('SELECT * FROM table'); while($row = $db->fetch_assoc()){ $arr[] = $row; } foreach($arr as $a){ $db->query(); // query and processing here } Is this the best method or am I missing the obvious? Should I consider passing a connection link ID with the database connection?

• SQL Server 2003: how can I assign a name to the SUM column ?

  - by Patrick

  hi, how can I assign a column name to the SUM column ? i.e. select OwnerUserId, SUM(PostScore) INTO Experts from ... I get this error: An object or column name is missing or empty. For SELECT INTO statements, verify each column has a name. For other statements, look for empty alias names. Aliases defined as "" or [] are not allowed. Change the alias to a valid name. I guess because the column containing the results of SUM has not name. thanks
