  • How to hide an dom element after creating it on the fly with Jquery ?

    - by ismaelsow
    I am trying to build a form where users can add a text field by clicking on a "add option" button. They can also remove added fields by a "remove option" link created on the fly by Jquery, along with the text field. My code looks like this : $(document).ready(function(){ $("#add_option").click(function(){ var form = $("form"); var input_field = '<input type="text" />'; var delete_link = '<a href="#">remove</a>'; form.append(input_field + delete_link); return false; }); $("a").click(function(){ alert('clicked'); return false; }); }); This code is not working : when I click on the "add_option" button, a new text field and the "delete_link" appear. But when clicking on the "delete_link" created by JQuery, the browser follows the link instead of launching a pop-up displaying "clicked". Any idea ? Thanks !

  • Navigation Controller not Pushing/Popping View Controllers

    - by senfo
    I'm working on a view-based iPhone app that has the following flow: search - (list | map) - details To accomplish the transitions between views, I have a UINavigationController, with the search view controller being the root. After a user performs a search, I transition to a view with a segmented control, which acts as a tab to switch between the list and map functionality (per a suggestion from a related question I had). This view contains a UIViewController, which allows me to switch between the list/map view when a user taps the segmented control. I'm fine up until this point. As you can see from the above mentioned flow, I would like to provide the ability to transition into a details view. Each row of my table in the list view contains a details disclosure button for allowing the user to drill down into a details view. The problem is, when I try to push the details view onto the navigation stack, nothing happens. Below is the delegate method (from my list view controller) to handle the details disclosure button being tapped. I've set up break points, so I know the code is running. The navigation controller simply doesn't want to push the detailsController onto the stack (my guess is that I don't have a pointer to the correct UINavigationController). - (void)tableView:(UITableView *)tableView accessoryButtonTappedForRowWithIndexPath:(NSIndexPath *)indexPath { if (detailController == nil) { detailController = [[DetailsViewController alloc] init]; } [self.navigationController pushViewController:detailController animated:YES]; } Assuming I was probably missing a pointer to the navigation controller, I exposed a UINavigation property on my list and map views (navigationController is readonly) and initialized them with a pointer to the navigation controller from my SwitchViewController (the view responsible for switching between list/map views when a user changes the value of the segmented control). Unfortunately, this did not solve the problem. Am I on the right track? If so, how do I see to it that my view has a pointer to the correct navigation controller? Should I add a delegate, which allows me to call a function in the SwitchViewController that transitions into the details view (this seems messy)?

  • WCF data services - Limiting related objects returned based on critera

    - by Mike Morley
    I have an object graph consisting of a base employee object, and a set of related message objects. I am able to return the employee objects based on search criteria on the employee properties (eg team) etc. However, if I expand on the messages, I get the full collection of messages back. I would like to be able to either take the top n messages (i.e. restrict to 10 most recent) or ideally use a date range on the message objects to limit how many are brought back. So far I have not been able to figure out a way of doing this: I get an error if I attempt to filter on properties on the message (&$filter=employee/message/StartDate gives an error "No property 'StartDate' exists in type 'System.Data.Objects.DataClasses.EntityCollection`1). Attempting to use Top on the message related object doesn't work either. I have also tried using a WebGet extension that takes a string list of employee IDs. That works until the list gets too long, and then fails due to the URL getting too long (it might be possible to setup a paging mechanism on this approach)... Unfortunately the UI control I am using requires the data to be in a fairly specific hierarchical shape, so I can't easily come at this from starting on the message side and working backwards. Outside of making multiple calls does anyone know of a method to accomplish this with wcf data services? Thanks! M.

  • Pass List of models to controller ASP.NET MVC 5

    - by user3697231
    I have a view where user can enter some data. But problem is this: Let's say you have 3 text box on view. Every time user can fill multiple times this 3 text boxes. To clarify, let's say user fills this 3 text boxes and press button which adds on form again these 3 text boxes. Now when user clicks submit this form is sent to controller, but how do I sent List of models as parameter. My architecture for this problem is something like this: MyModel public int ID { get;set; } public string Something { get; set; } /*This three textboxes can user set multiple times*/ /*Perhaps i Can create new model with these properties and then /*put List of that model as property here, but how to fill that list inside view ??*/ public string TextBoxOneValue { get; set; } public string TextBoxTwoValue { get; set; } public string TextBoxThreeValue { get; set; } Now, i was thinking that i Create PartialView with this 3 text boxes, and then when user clicks button on view another PartialView is loaded. And now, let's say I have Two partial views loaded, and user clicks submit, how that I pass list with values of these 3 text boxes to controller ??

  • How do I find the highest level TR that contains a specific ID nested in a table

    - by Mykroft
    I have some HTML that looks like this (NOTE: I know this code isn't great but I didn't design it originally and some of it is auto generated): <table id="tab1"> <tr> <td><span>Some text</span></td> <td><span>more text</span></td> <td><input type="text" id="inp1" onclick="DoSomething(this);" /></td> </tr> <tr> <td><span>Some text</span></td> <td><span>more text</span></td> <td><table id="tab2"> <tr><td><input type="radio" id="inp2" onclick="DoSomething(this);" /><span>item</span></td></tr> </table></td> </tr> </table> All of that is embedded in a table which is also embedded in a table and so on. In the DoSomething(this) function I want to retrieve the TR underneath the table tab1. I'm having trouble figuring out the jquery necessary for this. Currently I'm doing something like this: function DoSomething(control) { var parentTab = '<%=tab1.ClientID %>'; var tr = $('#' + parentTab + ' > tbody > tr').has('#' + $(control).attr('id')).get(0); } This seems really messy but works. Is there a cleaner way to do this? If it helps the input inside the table will always be a radio button and a radio button will never appear outside of a sub table. Ideally I'd like to do this without having to know the id of tab1 but that seems impossible.

  • How can show data from another form

    - by Michael Quiles
    This is basically a tic tac toe game, and I have another form called Winner.cs when a player wins I want it to call the form (this part works) and then I want it to say xWinner.label =b1.text"" + has won the game!. the part I cant get to work is displaying the text in the winners form label. There's an example of a message box that commented out for reference instead of b1.text using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Windows.Forms; namespace MyGame { public class Result1 { static private int[,] Winners = new int[,] { {0,1,2}, {3,4,5}, {6,7,8}, {0,3,6}, {1,4,7}, {2,5,8}, {0,4,8}, {2,4,6}, }; static public bool CheckWinner(Button[] myControls) { bool gameOver = false; for (int i = 0; i < 8; i++) { int a = Winners[i, 0], b = Winners[i, 1], c = Winners[i, 2]; Button b1 = myControls[a], b2 = myControls[b], b3 = myControls[c]; if (b1.Text == "" || b2.Text == "" || b3.Text == "") continue; if (b1.Text == b2.Text && b2.Text == b3.Text) { b1.BackColor = b2.BackColor = b3.BackColor = System.Drawing.Color.LightCoral; b1.Font = b2.Font = b3.Font = new System.Drawing.Font("Microsoft Sans Serif", 32F, System.Drawing.FontStyle.Italic & System.Drawing.FontStyle.Bold, System.Drawing.GraphicsUnit.Point, ((System.Byte)(0))); gameOver = true; Form xWinnerForm = new xWinnerForm(); xWinnerForm.Show(); //MessageBox.Show(b1.Text + " .... Wins the game!", "Game End", MessageBoxButtons.OK); //break; } } return gameOver; } } }

  • How to get JTree expanded?

    - by Dzmitry Zhaleznichenka
    I have a wizard with several screens where user has to fill his/her details for further processing. At the second screen I have a radio group with three radio buttons that enable additional elements. To proceed, user has to choose one of them. When user selects third button, single-selection JTree filled in with data enables and user has to select an option from it. Then user has to press "Next" to get to next screen. The option he\she had selected is stored as a TreePath. So far so good. My problem is the following. If the user wants to come back from the following screen to the screen with a JTree, I want to provide him\her with the JTree expanded to the option that had been selected and to highlight the option. However, whatsoever I try to do for that (any combinations of expandPath, scrollPathToVisible, addSelectionPath, makeVisible) always provides me with a collapsed tree. I try to expand both leaves and nodes. My code looks like this: rbProcessJTree.setSelected(isProcessJTree()); if (null != getSelectedTablePath()){ trTables.addSelectionPath(getSelectedTablePath()); trTables.expandPath(getSelectedTablePath()); trTables.scrollPathToVisible(getSelectedTablePath()); } When setSelected() is called, state change listener is invoked that enables JTree. The model is loaded during the form initialization. Each time I switch between screens, I save the input data from previous screen and dispose it. Then, when I need to open previous screen back, I save data from the following screen, dispose it, load data to this screen and show it. So each time the screen is generating from scratch. Could you please explain, what sequence of operations has to be done to get JTree expanded in a newly created form,with data model loaded and selection path provided?

  • Advice on Minimizing Stored Procedure Parameters

    - by RPM1984
    Hi Guys, I have an ASP.NET MVC Web Application that interacts with a SQL Server 2008 database via Entity Framework 4.0. On a particular page, i call a stored procedure in order to pull back some results based on selections on the UI. Now, the UI has around 20 different input selections, ranging from a textbox, dropdown list, checkboxes, etc. Each of those inputs are "grouped" into logical sections. Example: Search box : "Foo" Checkbox A1: ticked, Checkbox A2: unticked Dropdown A: option 3 selected Checkbox B1: ticked, Checkbox B2: ticked, Checkbox B3: unticked So i need to call the SPROC like this: exec SearchPage_FindResults @SearchQuery = 'Foo', @IncludeA1 = 1, @IncludeA2 = 0, @DropDownSelection = 3, @IncludeB1 = 1, @IncludeB2 = 1, @IncludeB3 = 0 The UI is not too important to this question - just wanted to give some perspective. Essentially, i'm pulling back results for a search query, filtering these results based on a bunch of (optional) selections a user can filter on. Now, My questions/queries: What's the best way to pass these parameters to the stored procedure? Are there any tricks/new ways (e.g SQL Server 2008) to do this? Special "table" parameters/arrays - can we pass through User-Defined-Types? Keep in mind im using Entity Framework 4.0 - but could always use classic ADO.NET for this if required. What about XML? What are the serialization/de-serialization costs here? Is it worth it? How about a parameter for each logical section? Comma-seperated perhaps? Just thinking out loud. This page is particulary important from a user point of view, and needs to perform really well. The stored procedure is already heavy in logic, so i want to minimize the performance implications - so keep that in mind. With that said - what is the best approach here?

  • Convert a binary tree to linked list, breadth first, constant storage/destructive

    - by Merlyn Morgan-Graham
    This is not homework, and I don't need to answer it, but now I have become obsessed :) The problem is: Design an algorithm to destructively flatten a binary tree to a linked list, breadth-first. Okay, easy enough. Just build a queue, and do what you have to. That was the warm-up. Now, implement it with constant storage (recursion, if you can figure out an answer using it, is logarithmic storage, not constant). I found a solution to this problem on the Internet about a year back, but now I've forgotten it, and I want to know :) The trick, as far as I remember, involved using the tree to implement the queue, taking advantage of the destructive nature of the algorithm. When you are linking the list, you are also pushing an item into the queue. Each time I try to solve this, I lose nodes (such as each time I link the next node/add to the queue), I require extra storage, or I can't figure out the convoluted method I need to get back to a node that has the pointer I need. Even the link to that original article/post would be useful to me :) Google is giving me no joy. Edit: Jérémie pointed out that there is a fairly simple (and well known answer) if you have a parent pointer. While I now think he is correct about the original solution containing a parent pointer, I really wanted to solve the problem without it :) The refined requirements use this definition for the node: struct tree_node { int value; tree_node* left; tree_node* right; };

  • Book/topic recommendations for a programmer returning to programming.

    - by Jason Tan
    I used to be a developer in Java, PHP, perl and C/C++ (the C++ bit badly - the others not too badly, I hope). This was back in the Java 1.3/1.4 days. We used raw JDBC, swing, servlets, JSP and ant (sometimes even make). Eclipse was new. Then I joined a deployment team and became a deployment engineer and then after the deployment engineer work became a full time sys admin.You get the idea - my experience is a generation or two old in programming terms - maybe older. I'm interested in getting back into Java and perhaps Ruby development, but feel I will be waaaaay behind the technological 8 ball. Can you folks suggest some books (or sites) that would be worth reading to catch up with the last 5-10 years of the development world. I.e. what should I read to try and catch up with where development is now? I see lots of stuff on the web, but what are people in the fabled "real world" using? (are lots of people being SOA based apps? Are they using XP methodology) The sorts of things I'm interested in finding out about/catching up on are: Methodologies Design patterns APIs/Frameworks/Technologies Other stuff you deem current/interesting/relevant. So if you have any thoughts or can recommend any books (especially new classics - you know the 's equivalent to K&R C or "The mythical man month"). Thanks for any thoughts you might share.

  • Is it possible to auto update only selected properties on an existent entity object without touching the others

    - by LaserBeak
    Say I have a bunch of boolean properties on my entity class public bool isActive etc. Values which will be manipulated by setting check boxes in a web application. I will ONLY be posting back the one changed name/value pair and the primary key at a time, say { isActive : true , NewsPageID: 34 } and the default model binder will create a NewsPage object with only those two properties set. Now if I run the below code it will not only update the values for the properties that have been set on the NewsPage object created by the model binder but of course also attempt to null all the other non set values for the existent entity object because they are not set on NewsPage object created by the model binder. Is it possible to somehow tell entity framework not to look at the properties that are set to null and attempt to persist those changes back to the retrieved entity object and hence database ? Perhaps there's some code I can write that will only utilize the non-null values and their property names on the NewsPage object created by model binder and only attempt to update those particular properties ? [HttpPost] public PartialViewResult SaveNews(NewsPage Np) { Np.ModifyDate = DateTime.Now; _db.NewsPages.Attach(Np); _db.ObjectStateManager.ChangeObjectState(Np, System.Data.EntityState.Modified); _db.SaveChanges(); _db.Dispose(); return PartialView("MonthNewsData"); } I can of course do something like below, but I have a feeling it's not the optimal solution. Especially considering that I have like 6 boolean properties that I need to set. [HttpPost] public PartialViewResult SaveNews(int NewsPageID, bool isActive, bool isOnFrontPage) { if (isActive != null) { //Get entity and update this property } if (isOnFontPage != null) { //Get entity and update this property } }

  • Creating Modules for VB Program (Similar to firefox add on)

    - by Assimilater
    Hi all. I have a contact manager program that I'd like to design for multiple network marketing companies. My desired structure would include a core program which covers basic contact management functions. After that one could purchase a module for their specific network marketing company. This module would contain a variety of controls that the original program would need to be able to manipulate. Here is an example of what it would have to have: A group box containing buttons that link to a genealogy view, and the option to import one's donwnline from the back office provided by a company. A panel which is displayed on the contact page allowing the user to input business information or which will be filled by importing a downline from the back office: ie business ID, qualification level, sponsor information etc. a panel displayed when one searches for contacts on the contact list page which allows the user to sort based on information such as when they joined, what their business id is and so forth. a panel which is displayed in a personal business overview page which presents to an individual how many people in their downline are at each qualification level and develop a mailing list for individuals of a certain qualification level. I have the code developed to perform all these functions, I just wanted to give you an example of what needed to be done. I'm thinking that what I'm trying to create is a library that one can download and the program will recognize, but I'm not really sure where to go. What I'm really trying to do is figure out what kind of file I can make that will contain all this code and the GUI information that the program will recognize. Any ideas? With thanks, John

  • IE AJAX/Jquery issue - redirecting to new page instead of loading it into a div

    - by phx-zs
    I have a page like this: <form class="ajax" method="post" action="add_item.php"> [text input] [submit button] </form> [list any items the user has in a div here called #items] When the user clicks the submit button, a function like this is called: $("form.ajax").live('submit', function(event) { params = $(this).serialize(); $.post($(this).attr("action"), params, function(data){ json = $.parseJSON(data); // do stuff based on the json results if(json.success.action == 'replace'){ $(json.success.container).html(json.success.message); } else{ $(json.success.container).prepend(json.success.message); $(json.success.container).find(".item:first").slideDown(); } }); event.returnValue = false; return false; }); This is supposed to load add_item.php into the #items div, and it works fine in FF, Chrome, Safari, just not IE. In IE (tested 7 and 8) when I click Submit it redirects the page to add_item.php rather than loading it into the #items div. I tried adding event.preventDefault(); to the end of the function but that didn't work. Any ideas?

  • How do I put my return data from an asmx into JSON?

    - by jphenow
    I want to return an array of javascript objects from my asp.net asmx file. ie. variable = [ { *value1*: 'value1', *value2*: 'value2', ..., }, { . . } ]; I seem have been having trouble reaching this. I'd put this into code but I've been hacking away at it so much it'd probably do more harm than good in having this answered. Basically I am using a web service to find names as people type the name. I'd use a regular text file or something but its a huge database that's always changing - and don't worry I've indexed the names so searching can be a little snappier - but I would really prefer to stick with this method and just figure out how to get usable JSON back to javascript. I've seen a few that sort of attempt to describe how one would approach this but I honestly think microsofts articles are damn near unreadable. Thanks in advance for assistance. EDIT: I'm using the $.ajax() function from jQuery - I've had it working but it seems like I was doing it in bad practice not returning and using actual JSON. Previously I'd take a string back and insert it into html to use the variable it set - very roundabout.

  • Datastructure choices for highspeed and memory efficient detection of duplicate of strings

    - by Jonathan Holland
    I have a interesting problem that could be solved in a number of ways: I have a function that takes in a string. If this function has never seen this string before, it needs to perform some processing. If the function has seen the string before, it needs to skip processing. After a specified amount of time, the function should accept duplicate strings. This function may be called thousands of time per second, and the string data may be very large. This is a highly abstracted explanation of the real application, just trying to get down to the core concept for the purpose of the question. The function will need to store state in order to detect duplicates. It also will need to store an associated timestamp in order to expire duplicates. It does NOT need to store the strings, a unique hash of the string would be fine, providing there is no false positives due to collisions (Use a perfect hash?), and the hash function was performant enough. The naive implementation would be simply (in C#): Dictionary<String,DateTime> though in the interest of lowering memory footprint and potentially increasing performance I'm evaluating a custom data structures to handle this instead of a basic hashtable. So, given these constraints, what would you use? EDIT, some additional information that might change proposed implementations: 99% of the strings will not be duplicates. Almost all of the duplicates will arrive back to back, or nearly sequentially. In the real world, the function will be called from multiple worker threads, so state management will need to be synchronized.

  • How to change image on locale base in magento?

    - by Nil
    I want to change search image in magento. On search in magento the image name is btn_search.gif. Right now it take image from skin/frontend/default/default/images. And the file is /app/design/frontend/default/default/template/catalogsearch/form.mini.phtml where mention this tag as <input id="search-button" type="image" src="<?php echo $this->getSkinUrl('images/btn_search.gif') ?>" alt="<?php echo $this->__('Search') ?>" /> I check the code and i found that we can pass locale as _type in this as <input id="search-button" type="image" src="<?php echo $this->getSkinUrl('images/btn_search.gif', array('_type'=>'local')) ?>" alt="<?php echo $this->__('Search') ?>" /> But when i check the code this will just check in locale directory that this file exist in that locale or not. If this exist then it will take skin image. I want to use that locale image instead of that skin image. So when i click on french store i get the image which is i set in /app/design/frontend/default/default/locale/fr_FR/images/btn_search.gif I check the code for getSkinUrl in /app/code/core/Mage/Core/Model/Design/Package.php. And i found that he check locale for file but it return skin url. Is there any method which return locale url ?

  • Extremely Difficult Problem with ASP.Net 4.0 WebForms app using Routing

    - by dudeNumber4
    I have a completed app running in a QA environment. Everything works fine under most circumstances. If you hit a plain URL (no identifying information in the URL), you see an intro page with a button (generated by an asp LinkButton control) that posts back and directs you to another page. The markup looks the same when it fails and when it doesn't. When such a URL is followed from, e.g., Word and the default browser is IE, the intro page loads fine, but clicking the button causes an error. When not debugging, this behavior occurs every time. While debugging, the error occurs only ~ 1 in 10 times (closing the browser instance and starting over every time). When the error occurs, the intro page Page_Load fires and IsPostBack is false. Somehow, instead of a post, a get is being issued. When I run fiddler to try to analyze the actual calls (can't use firebug because it never happens using Firefox), everything works every time. I don't know whether this issue has anything to do with routing, and I've no idea even what to look at next. The strange thing is, when I debug, the intro page doesn't fully load every time. Only about 1 in 3 times does it fully load even if I've just cleared browser cache. When I run it through fiddler, it fully loads and works fine every time.

  • Access Question

    - by kralco626
    I have a record set for inspections of many peices of equipment. The four cols of interest are equip_id,month,year,myData. My requirment is to have EXACTLY ONE Record per month for each peice of equipment. I have a quiery that makes the data unique over equip_id,month,year. So there is no more than one record for each month/year for a peice of equipment. But now I need to simulate data for the missing month. I want to simply go back in time to get the last peice of my data. So that may seem confusing, so i'll show by example. Given this: equip_id month year myData 1 1 2010 500 1 2 2010 600 1 5 2010 800 2 2 2010 300 2 4 2010 400 2 6 2010 500 I want this: equip_id month year myData 1 1 2010 500 1 2 2010 600 1 3 2010 600 1 4 2010 600 1 5 2010 800 2 2 2010 300 2 3 2010 300 2 4 2010 400 2 5 2010 400 2 6 2010 500 Notice that im filling in missing data with the data from the month ( or two months etc.) before. Also note that if the first record for equip 2 is in 2/2010 than I don't need a record for 1/2010 even though I have one for equip 1. I just need exactly one record for each month/year for each peice of equipment. So if the record does not exsist I just want to go back in time and grab the data for that record. Thanks!!!

  • How can I use a value of JSP in Javascript code?

    - by novellino
    Hello, I have a list of elements, each of them appeared in my page through jsp. So I have this: <div id="title"><%= list.get(ind).getTitle() %></div> When I display the elements, as this tag is in for loop, I get everything right. Now I what to place a button for deleting each of this elements. What I have done is: <input type="submit" name="submit" onclick="deleteNewsFunction();" id="submit_btn"/> In the deleteNewsFunction() I just want to print the data. <script> function deleteNewsFunction(){ var item = $('#title').val(); alert(item); } </script> The problem is that the title var gets always the first item even if I am clicking on the button of the second item. I was thinking that maybe a solution is to add the "list.get(ind).getTitle()" as a parameter in the function like deleteNewsFunction(<%=list.get(ind).getTitle()%) but then it did not work at all. Does anyone know how to help me? Thanks a lot!

  • WP7 - group of textboxes into some sort of template?

    - by Jeff V
    I'm still pretty new at Silverlight so there might be a way to do this, but I'm just unfamiliar with the terminology... I basically have this grouping of textboxes and textblocks and I would like to repeat this same grouping whenever the addNew button is clicked. Is there a way to do this by creating some sort of template? Or do I have to add each item individually. <Grid> <toolkit:ListPicker Height="70" HorizontalAlignment="Right" Name="listPicker1" VerticalAlignment="Top" Width="56" ItemTemplate="{StaticResource PickerItemTemplate}" FullModeItemTemplate="{StaticResource PickerFullModeItemTemplate}" Margin="0,97,167,0"></toolkit:ListPicker> <TextBlock Height="33" HorizontalAlignment="Left" Margin="10,7,0,0" Name="tbDate" Text="Date:" VerticalAlignment="Top" Width="266" /> <TextBlock Height="42" HorizontalAlignment="Left" Margin="9,55,0,0" Name="tbItem" Text="Item:" VerticalAlignment="Top" Width="90" /> <TextBox Height="75" HorizontalAlignment="Left" Margin="92,33,0,0" Name="tbItemName" Text="" VerticalAlignment="Top" Width="341" /> <TextBlock Height="42" HorizontalAlignment="Left" Margin="5,118,0,0" Name="tbServing" Text="Serving:" VerticalAlignment="Top" Width="99" /> <TextBox Height="70" HorizontalAlignment="Left" Margin="90,96,0,0" Name="tbServingValue" Text="" VerticalAlignment="Top" Width="75" /> <TextBlock Height="42" HorizontalAlignment="Left" Margin="156,120,0,0" Name="tbUOM" Text="UOM:" VerticalAlignment="Top" Width="60" /> <Button Content="" HorizontalAlignment="Right" Height="63" Margin="0,100,13,0" VerticalAlignment="Top" Width="132" RenderTransformOrigin="0.455,0.286" Style="{StaticResource wp7_buttonAddNew}" x:Name="btnAddNewItem" Click="btnAddNewItem_Click"/> </Grid> Thanks!

  • Handling Complex Rules in in GUI applciations (C++ or C#)

    - by Canacourse
    Im working on a dialog box in which several rules must be satisfied before the OK button is enabled. Currently any action on the page such as entering data or selecting an item from a drop down list (amongst other things) calls a single function called ProcessEvent() - this function handles all logic and either enables or disables the OK button. My problem is I finding it difficult making the rules concise and understandable. Some of the rules can be negated by another action on the dialog and I have now ended up with if else statements all over the place or which are difficult to read and follow & extend. The code below is a simplification of the problem but demonstrates it well. How do I handle this problem better (If its Possible) bool CWorkstation::ProcessEvent(void) { UpdateData(); CharCount = GetDlgItemInt(IDC_CharCount, NULL, FALSE); //get latest if ( IsDlgButtonChecked(IDC_USEDBNAME)) { if (!IsDlgButtonChecked(IDC_MAXDBNAME)) { EnableNext(TRUE); } } if (IsDlgButtonChecked(IDC_MAXDBNAME) && CharCount) { if (IsDlgButtonChecked(IDC_USEXMLNAME)) { if ( PrefixName.IsEmpty() ) { EnableNext(FALSE); } else { EnableNext(TRUE); } } } if (IsDlgButtonChecked(IDC_USEXMLNAME) && PrefixName.GetLength() > 1) { EnableNext(TRUE); } if ( IsDlgButtonChecked(IDC_WSAUTONAME) || IsDlgButtonChecked(IDC_RENAMEIFDUP)) { // TRACE("IDC_WSAUTONAME is Checked\n"); if ( IsDlgButtonChecked(IDC_USEXMLNAME) && PrefixName.GetLength() > 1 ) { if ( IsDlgButtonChecked(IDC_IDC_USESHORTNAME) ) { EnableNext(TRUE); } else if ( IsDlgButtonChecked(IDC_USELONGNAME) ) { EnableNext(TRUE); } else { EnableNext(FALSE); } } if ( !IsDlgButtonChecked(IDC_USEPREFIX) ) { if ( IsDlgButtonChecked(IDC_IDC_USESHORTNAME) || IsDlgButtonChecked(IDC_USELONGNAME) ) { EnableNext(TRUE); } } return false; } }

  • cfdiv working in FF and Safari but does not show up in IE

    - by JS
    Within a form I have a button that launches a cfwindow, then presents a search screen for the user to make a selection. Once selection is made, the cfwindow closes and the selected content shows in the main page by being bound to a cfdiv. This all works fine in FF but the cfdiv doesn't show at all in IE. In IE, the cfwindow works, the select works, but then no bound page. I have tried setting bindonload and that made no difference (and I need it to be true if there is content that is pulled in via a query when it loads). All I have been able to find so far regarding this issue is setting bindonload to false and putting the cfdiv outside of the form but that's not possible in my current design. Here is a snippet which is inside of a larger form (and all necessary tags are cfimported). <td class="left" style="white-space:nowrap;"> <cfoutput>#n#</cfoutput>.&nbsp;<cfinput type="button" value="Select" name="x#n#Select#i#" onClick="ColdFusion.Window.create('x#n#Select#i#', 'Exercise Lookup', 'xSelect/xSelect.cfm?xNameVar=x#n#S#i#&window=x#n#Select#i#&workout=workout#i#', {x:100,y:100,height:500,width:720,modal:true,closable:true,draggable:true,resizable:true,center:true,initshow:true,minheight:200,minwidth:200 })" /> &nbsp; <cfdiv id="x#n#S#i#" tagName="x#n#S#i#" bind="url:xSelect/x.cfm"></cfdiv> <cfinput type="hidden" name="x#n#s#i#" value="#n#"> </td> Thanks for any help.

  • Is it okay for multiple objects to retain the same object in Objective-C/Cocoa?

    - by Andrew Arrow
    Say I have a tableview class that lists 100 Foo objects. It has: @property (nonatomic, retain) NSMutableArray* fooList; and I fill it up with Foos like: self.fooList = [NSMutableArray array]; while (something) { Foo* foo = [[Foo alloc] init]; [fooList addObject:foo]; [foo release]; } First question: because the NSMutableArray is marked as retain, that means all the objects inside it are retained too? Am I correctly adding the foo and releasing the local copy after it's been added to the array? Or am I missing a retain call? Then if the user selects one specific row in the table and I want to display a detail Foo view I call: FooView* localView = [[FooView alloc] initWithFoo:[self.fooList objectAtIndex:indexPath.row]]; [self.navigationController pushViewController:localView animated:YES]; [localView release]; Now the FooView class has: @property (nonatomic, retain) Foo* theFoo; so now BOTH the array is holding on to that Foo as well as the FooView. But that seems okay right? When the user hits the back button dealloc will be called on FooView and [theFoo release] will be called. Then another back button is hit and dealloc is called on the tableview class and [fooList release] is called. You might argue that the FooView class should have: @property (nonatomic, assign) Foo* theFoo; vs. retain. But sometimes the FooView class is called with a Foo that's not also in an array. So I wanted to make sure it was okay to have two objects holding on to the same other object.

  • Action listener for JButton array

    - by user530809
    Let's say I have a program with 2D array of buttons, and when you click one of them it turns red. I didn't want to declare every single button seperately so I just created JButton[][] array for them. The problem is that I don't know how to use action listener on any of the buttons in the array so it would change the color of this particular button, and none of related questions is relevant to this. I tried to use "for" but it doesn't help: package appli; import javax.swing.*; import java.awt.*; import java.awt.event.*; public class MainW extends JFrame implements ActionListener { public MainW(){ setSize(640,480); setTitle("title"); setLayout(null); JButton[][] btnz = new JButton[5][5]; for(Integer i=0;i<5;i++) { for(Integer j=0;j<5;j++) { btnz[i][j]= new JButton(""); btnz[i][j].setBackground(Color.WHITE); btnz[i][j].setBounds(10+20*i,10+20*j,20,20); add(btnz[i][j]); btnz[i][j].addActionListener(this); } } setDefaultCloseOperation(EXIT_ON_CLOSE); setVisible(true); } public void actionPerformed(ActionEvent e){ for(Integer i=0;i<5;i++) { for(Integer j=0;j<5;j++) { if (e.getSource()==btnz[i][j]); { btnz[i][j].setBackground(Color.RED); } } } } }
