• How to set DataGridView columns text format to uppercase by adding new property?

  - by Jooj

  Hello, I have a custom DataGridView control and want to set the text format for custom columns in the designer (CellStyle builder). Let's say I want to make the text format to uppercase. After searching about this I've found some solutions with adding new events and then changing the text format but this is not what I want. I want to add a new property to all designed columns and there set or change the text format. How to do this? Thank and best regards.

• Multiple selection in a TreeView

  - by Frederick

  I am using a Windows Forms TreeView control in my program. I would like to allow the user to select multiple nodes at the same level by dragging their mouse pointer around (also called a "lasso" selection). I don't think a standard TreeView allows that. My question is what would be the best way to achieve this? Do I have to write custom selection behaviour of my own in perhaps a custom or derived control? Where do I start? I don't need a detailed explanation. Just a small nudge in the right direction.

• asp.net web form Cutom Router Handler

  - by jparram

  I am using a custom route handler for a webforms application. I am using routes to determine localization. ie: if the url has es or fr in the route it will load either spanish or french resources. for example: www.someroute/es/checkstuff/checkstuff.aspx will load: www.someroute/checkstuff/checkstuff.aspx with the spanish resources. I am configuring the custom routes in global.asax via: protected void Application_Start(object sender, EventArgs e) { RegisterRoutes(RouteTable.Routes); } public static void RegisterRoutes(RouteCollection routes) { foreach (var value in _customRoutes) { routes.Add(value.RouteName, new Route(value.Route, new CustomRouteHandler(value.ResolvedRoute))); } } where _customroutes is a list of routes. Is there a way to do this with some kind of pattern matching so I can avoid adding a specific route for each page in the application. While I know I could use a t4 template to generate the routes, I guess I am looking for a dynamic way to create the list

• Android preferencesActivity setDefaultValue() not working?

  - by Nick

  I'm extending PreferenceActivity for my settings screen. In this preference activity i have a couple of preferences one of which is custom made. The problem is as follows: in this custom preference (which extends from ListPreference) i want to be able to set the default value, so i override the setDefaultValue() method. In this method i do some parsing so it'll take the correct value. When i'm trying to read this value with the getValue() function it just returns null. So i figured, what happens when i just put some hardcoded value in there (you know, maybe i did something wrong, wouldn't be the first time). Well, i still get null back. Any ideas what i'm doing wrong? Edit: Setting the defaultValue in the xml file isn't really an option because the values aren't known until i retrieve them. I made a workaround: When app is started for the first time: get data Set the values in the preference. This way i set the default preference when i'm collection the data

• Creating Pages with unique PageMaps

  - by Michael Krauklis

  I have a wicket Application that has long lived Pages. I would like each instance of this Page to be created with a unique PageMap for reasons I won't get into here, but when I try to specify a PageMap on the constructor of my Page I end up getting OOM and StackOverflow errors. Here is the code: public <CTOR>() { super(Session.get().newPageMap("" + System.currentTimeMillis())); ... I'm using a custom BookmarkablePageLink (custom in that it does not pass on the current PageMap name to the new Page) to effectively abandon the old Page/PageMap and create a new one with a new PageMap. The errors seem to be coming from page serialization after only two or three pages have been created. Can anyone find issue with this approach?

• Adding dynamic content with events in jquerymobile

  - by Christian Waidner

  Currently I'm stuck with a problem in jquerymobile: I'm adding items to a list dynamically and use enhanceWithin() in the end (so styling is correct). After this I like to add click-events for each list item but the problem is, that enhanceWithin runs asynchronous and so I always get the error message "cannot call methods on checkboxradio prior to initialization; attempted to call method 'refresh'" When I delay the event-adding-code it works perfectly. Does anyone have an idea if there is a enhanceWithin.done event or anything else I can use? HTML: ... <div id="shoppinglist">Loading list...</div> ... Javascript: function updateList() { var result = ""; $.each(shoppinglistItems, function (index, item) { result += '<label><input type="checkbox" ' + item.checked + ' id="item_' + item.id + '">' + item.name + '</label>\n'; }); $('#shoppinglist').html(result).enhanceWithin(); // Change-Events an die Checkboxen knoten $('input[id*=item_]').unbind('change').bind('change', function (event) { var itemid = $(this).attr('id'); itemid = (itemid.split('_'))[1]; // Nur die Zahl extrahieren // Passendes Item aus der Liste der Items suchen und checken $.each(shoppinglistItems, function (index, item) { if (item.id == itemid) { item.checked = "checked"; item.timestamp = moment().format("YYYYMMDDHHmmss"); } }); updateList(); }); }

• Ajax Update Panel Not Displaying Updated Image in IE, Chrome and FireFox

  - by jmease

  I have a parent page with an Ajax Update Panel that contains an image and a button. There is a hyperlink that opens up a child page. When the child page is submitted, there is an onclientclick event that triggers a javascript function that clicks the button in the update panel on the parent page, the button's click event being the trigger for the panel as well as the event that updates the image URL. When I use this on my android tablet, it works perfectly. However, it doesn't work at all on any browser I've used on a PC (Windows XP). The Image URL updates, but the updated image doesn't display without refreshing the entire page. In IE, I can right click on the image and click Show Image and it updates. In Chrome and Firefox, I have to refresh the entire page. Why would an Ajax control only work properly on the Android OS and what could I be doing wrong that would cause the image not to redisplay on my PC without refreshing the page even though the image URL is clearly being updated properly. I suspect a caching issue, but don't know how to correct.

• Help - use PHP-broswer, or proxy or get_page_contents or include page, or something else ??

  - by userlite

  Hi, I am trying to develop a web application for which I need to capture a specific user-driven event (such as mouse dblclick) occurring on a different-website page loaded through my website. What I want to do is : User visits my website - hosted by me. There, user types in any website URL (e.g.: http://www.example.com) That URL page gets loaded as is. When user double-clicks mouse over any link or image from that page, a popup/side-panel is displayed with content related to that particular image or link. I can do this with a combination of PHP get_page_contents or include-page, and javascript dblclick. However, when user clicks on any link or submits a form, the control goes to that other website, where I cannot show the side-panel. I might be able to handle the links by proxifying them when user clicks on any of them. How do I handle forms submission and other stuff ? I can use a full-featured proxy, but that will be too heavy just for the purpose of capturing the event. My question is that is there a way to write some kind of light PHP script that sits on my website - that loads other websites contents as is, but lets me capture the mouse-dblclick event to show related-content in the side panel . I have already searched the internet, but could not find anything. Any help is really appreciated. Thanks.

• Moving x,y position of all array objects every frame in actionscript 3?

  - by Dylan Gallardo

  I have my code setup so that I have an movieclip in my library a class called "block" being duplicated multiple times and added into an array like this: function makeblock(e:Event){ newblock=new block; newblock.x=10; newblock.y=10; addChild(newblock); myarray[counter] = newblock; //adds a newblock object into array counter += 1; } Then I have a loop with a currently primitive way of handling my problem: stage.addEventListener(Event.ENTER_FRAME, gameloop); function gameloop(evt:Event):void { if (moveright==true){ myarray[0].x += 5; myarray[1].x += 5; myarray[2].x += 5 -(and so on)- My question is how can I change x,y values every frame for new objects duplicated into the array, along with the previous ones that were added. Of course with a more elegant way than writing it out myself... array[0].x += 5, array[1], array[2], array[3] etc. Ideally I would like this to go up to 500 or more array objects for one array so obviously I don't want to be writing it out individually haha, I also need it to be consistent with performance so using a for loop or something to loop through the whole array and move each x += 5 wouldn't work would it? Anyway, if anyone has any ideas that'd be great!

• Rails - Create if record doesn't exist or else update.....Whats Best way to do this?

  - by ChrisWesAllen

  Hi, I have a create statement for some models but its creating a record within a join table regardless if the record exist. Here is what my code looks like. @user = User.find(current_user) @event = Event.find(params[:id]) for interest in @event.interests @user.choices.create(:interest => interest, :score => 4) end The problem is it creates records no matter what. I would like it to create a record if it doesnt exist, if a record does exist I would just to it to take the attribute of the found record and add or subtract 1. So, I've been looking around and I see something called find_or_create_by. My question is what happens if it finds? Preferably if it finds,I would like to take the current :score attribute and +1. SO is it possible to find or create by id? I'm not sure what attribute I would find by since the model I'm looking at is a join model which only had id foreign keys and the score attribute. I tried @user.choices.find_or_create_by_user(:user => @user.id, :interest => interest, :score => 4) but got "undefined method `find_by_user'".....ANy ideas or help?

• How do I display each view once as they are loaded, in Android?

  - by Joe Masilotti

  I have an Android application that works off of a smaller database, around 300 entries. To view the database, I have created a custom view that contains individual rows of data. Then I query the database, and add each line to a newly created custom view. The problem is that it takes a little white for all of this to be created/loaded, so when you open the application, it sits for a few seconds. How can I load one line of data, then display it, then the next, append it, etc.?

• creating events in my classes, and allowing others to hook into them in my django app

  - by Blankman

  I want to create events for my classes. Say I create a CMS application that has a Article object. I create events like: OnEdit OnCreate OnDelete PreCreate PreDelete Now I want someone to be able to hook into these events, and add their custom functionality at each event they wish. I don't want them touching the core source code, so they would have to wire these custom methods to fire somewhere else. I'm new to both python and django so please be as detailed as possible if you can.

  - by ChrisWesAllen

  I have setup this HABTM relationship in the past and its worked before....Now it isnt and I'm at my wits end trying to figure out whats wrong. I've looking through the rails guides all day and cant seem to figure out what I'm doing wrong, so help would really be appreciated. I have 2 models connected through a join model and I'm trying to find records based an attribute of the associated model. Event.rb has_and_belongs_to_many :interests Interest.rb has_and_belongs_to_many :events and a join table migration that was created like create_table 'events_interests', :id => false do |t| t.column :event_id, :integer t.column :interest_id, :integer end I tried @events = Event.all(:include => :interest, :conditions => [" interest.id = ?", 4 ] ) But got the error "Association named 'interest' was not found; perhaps you misspelled it?"... which I didnt of course I tried @events = Event.interests.find(:all, :conditions => [" interest.id = ?", 4 ] ) but got the error "undefined method `interests' for #Class:0x4383348" How can I find the Events that have an interest id of 4....I'm definitely going bald from this lol

• Component not listening to MainApp's state change

  - by tag

  I don't know if this is too difficult or too easy. My custom component is trying to listen to the main application's state changes using StateChangeEvent.CURRENT_STATE_CHANGE private function init(){ addEventListener(StateChangeEvent.CURRENT_STATE_CHANGE, function():void{ Alert.show("parent state changed"); }); } but as expected, it's reporting its own state changes not the main application's. I have 2 options: figure a way to tell it that I really mean the main application's state change not its own or configure the main application to dispatch a specific custom event that the component would listen for Any idea how I could do the first? or do I need the second option in this case?

• Drupal and Back-End Complexity

  - by Brian

  Currently I am working on a school website, and we are still in the decision-making process of choosing a framework (we know that we're not using Joomla! or hand-coding). Drupal came up as a viable choice, and currently, that is my best bet for the site. However, I have an issue with CMS's in general. I would like to develop a quite complicated and specifically custom-suited back-end application for teachers to interact with individual students, including the design of shared/custom calendars, announcement privileges, etc. I currently have a bit of expertise with HTML, CSS, PHP, MySQL, and I could wrap my head around some JavaScript and AJAX stuff if need-be. However, would such a complicated application work with Drupal (in that I could create it to specifically suite my purposes)?

• How to set an error message from EditorPart when ApplyChanges returns false?

  - by jmservera

  I'm developing a custom ASP.Net WebPart using the WebPartManager and I'm creating a custom EditorPart too. For its EditorPart.ApplyChanges method I set the return value to false whenever there is an error. In the EditorZone I get a standard error message indicating that some error happened to the editor, but I want to change that message. Is that possible? Something like... public override bool ApplyChanges() { try { // save properties return true; } catch(Exception ex) { ErrorMessage = ex.Message; // is there any similar property I can fill? return false; } }

• UITableView not showing background image.

  - by K.Honda

  I have a uitableview with 2 cells (custom tableviewcells) and a button for login. I made them programmatically. Now I want to put a background image behind the 2 custom cells and the button. I went into IB and put the image view on top of the tableview and then put a picture on it which I want as the background. Then I went into viewDidLoad and put this bit of code tblSimpleTable.backgroundColor = [UIColor clearColor]; to clear the tableviews background colour. It now looks like this: But the background does not appear. Does anyone know how to fix this? Thanks.

• Changing iframe visibility on Mozilla not working

  - by Honski

  I've got a simple iframe that I want hidden until an event from that iframe is fire via easyXDM. It's working fine on Chrome, but somehow not on Mozilla. The event is being fired on both browsers, but only shows the iframe on Chrome. The only way to show the iframe on Mozilla is to call the same code using an onclick event. HTML: <a href="#" onclick="shower(); return false;">show frame (always working)</a> <br> <iframe src="testsite.php" width="600" height="424" scrolling="no" border="0" id="my-iframe3" style="visibility: hidden;" onload="scrollIFrame();" name="my-iframe3"> Javascript: function shower() { document.getElementById("my-iframe3").style.visibility="visible"; } var socket = new easyXDM.Socket( { onMessage: function(message, origin) { if (message == "hi") { socket.postMessage("do something"); } else if (message == "ready") { shower(); } } }); Both browsers receive the "ready" message.

• loading remote page into DOM with javascript

  - by scoobydoo

  I am trying to write a web widget which will allow users to display customized information (from my website) in their own web page. The mechanism I want to use (for creating the web widget) is javascript. So basically, I want to be able to write some javascript code like this (this is what the end user copies into their HTML page, to get my widget displayed in their page) <script type="text/javascript"> /* javascript here to fetch page from remote url and insert into DOM */ </script> I have two questions: how do I write a javascript code to fetch the page from the remote url? Ideally this will be PLAIN javascript (i.e. not using jQuery etc - since I dont want to force the user to get third party scripts jQuery which may conflict with other scripts on their page etc) The page I am fetching contains inline javascript, which gets executed in an body.onLoad event, as well as other functions which are used in response to user actions - my questions are: i). will the body.onLoad event be triggered for the retrieved document?. ii). If the retrieved page is dumped directly into the DOM, then the document will contain two <body> sections, which is no longer valid (X)HTML - however, I need the body.onLoad event to be triggered for the page to be setup correctly, and I also need the other functions in the retrieved page, for the retrieved page to be able to respond to the user interaction. Any suggestions/tips on how I can solve these problems?

• How to stop a MFC/win32 control re-painting

  - by John

  I have a CRichEditCtrl, and an algorithm works on its contents in-place, iterating through the contents and making changes. This seems to cause it to re-paaint every time, which causes flickering and a noticeable time to complete the operation, especially if the control starts scrolling. I wondered if there's a neat way for me to stop it repainting for a period. It's actually a custom subclass of CRichEditCtrl in use so I was thinking something like: void MyCustomEditCtrl::DoAlgorithm() { enableRepaint(false); ... //to the actual work ... enableRepaint(true); } What's the neatest approach? A custom on-paint handler which does nothing when an operation is in progress? Or can repainting actually be disabled?

• Using AJAX in Rails: How do I change a button as soon as it's clicked?

  - by sdc

  Hey! I'm teaching myself Ruby, and have been stuck on this for a couple days: I'm currently using MooTools-1.3-compat and Rails 3. I'd like to replace one button (called "Follow") with another (called "Unfollow") as soon as someone clicks on it. I'm using :remote = true and have a file ending in .js.erb that's being called...I just need help figuring out what goes in this .js file The "Follow" button is in a div with id="follow_form", but there are many buttons on the page, and they all have an id = "follow_form"...i.e. $("follow_form").set(...) replaces the first element and that's not correct. I need help replacing the button that made the call. I looked at this tutorial, but the line below doesn't work for me. Could it be because I'm using MooTools instead of Prototype? $("follow_form").update("<%= escape_javascript(render('users/unfollow')) %") ps. This is what I have so far, and this works: in app/views/shared: <%= form_for current_user.subscriptions.build(:event => @event), :remote => true do |f| %> <div><%= f.hidden_field :event %></div> <div class="actions"><%= f.submit "Follow" %></div> <% end %> in app/views/events/create.js.erb alert("follow!"); //Temporary...this is what I'm trying to replace *in app/controllers/subscriptions_controller.rb* def create @subscription = current_user.subscriptions.build(params[:subscription]) @subscription.save respond_to do |format| format.html { redirect_to(..) } format.js {render :layout} end Any help would be greatly, greatly appreciated!
