  • Record Disappeared from Mysql Table, How Can I Find Out What Happened?

    - by Jascha
    I got the fire alarm phone call, AIM messages and email today from a client stating "The site is down!, WTF happened?!" Well, after a little digging, it turns out one of the records in a table had been wiped clean, but without removing the row itself. So, I had the representation of data, but a bunch of empty fields. (needless to day I need to write into my code a catch for this.) What my real question is, where can I figure out what happened? I've got access to phpmyadmin and that's about it. I found some access logs on in the root directory of my server, but that just tells me the client was in the admin area I built editing that record, I'd like to know specifically what they did that made all of the data go away. (what query was run etc...) is it possible without real server admin access? is there a neat little php to mysql class that returns data like this? Thanks in advance. -Jascha

  • How can I create a finger scrollable Textbox in WM 6.5?

    - by Papajohn
    Hi everybody. I just noticed something weird in WM 6.5 emulators. Unlike 6.1 where finger panning kind of worked, the only way to scroll a Textbox appears to be through scrollbars. This behaviour is in contrast to what they have done for comboboxes: they are now gesture-friendly without the programmer's intervention. I.e. the user can select a choice from a standard drop down menu by panning and scrolling. Previously, you had to use the embedded scrollbar. The combobox's case implies that MS took some measures to provide standard gesture support for classic finger gestures, yet I cannot see something similar for textboxes. This makes me ask the following: Is there anything that can be done to make textboxes finger scrollabe easily? Note that I refer to managed .NET CF development. It is my understanding that in native development I could use the new Gestures API to achieve the scrolling effect. Yet, I am not sure if there is an easier and more straightforward method that I have missed.

  • Dynamically change ViewPagerIndicator titles

    - by msal
    My current project uses some ListFragments to show rows of data. The rows get updated dynamically every some seconds. The amount of rows varies with every update and in every ListFragment. I would like to show the amount of rows to the user, and think that the perfect place for that would be next to the Fragment's title in the ViewPagerIndicator. I provided a sample image for better comprehension: Sadly I am pretty clueless how to achieve this. I tried the following: public class PagerAdapter extends FragmentPagerAdapter { private int numOne = 0; private int numTwo = 0; // ... @Override public CharSequence getPageTitle(int position) { switch (position) { case 0: return "List 1 (" + numOne + ")"; case 1: return "List 2 (" + numTwo + ")"; default: return ""; } public void setNumOne(int num) { this.numOne = num; } public void setNumTwo(int num) { this.numTwo = num; } } When I now call the setNumXXX() method, nothing happens, until I move between fragments, what seems to trigger the getPageTitle() to fire. My question is: How can I force an update of the title(s), everytime when the num value changes?

  • Have I taken a wrong path in programming by being excessively worried about code elegance and style?

    - by Ygam
    I am in a major stump right now. I am a BSIT graduate, but I only started actual programming less than a year ago. I observed that I have the following attitude in programming: I tend to be more of a purist, scorning unelegant approaches to solving problems using code I tend to look at anything in a large scale, planning everything before I start coding, either in simple flowcharts or complex UML charts I have a really strong impulse on refactoring my code, even if I miss deadlines or prolong development times I am obsessed with good directory structures, file naming conventions, class, method, and variable naming conventions I tend to always want to study something new, even, as I said, at the cost of missing deadlines I tend to see software development as something to engineer, to architect; that is, seeing how things relate to each other and how blocks of code can interact (I am a huge fan of loose coupling) i.e the OOP thinking I tend to combine OOP and procedural coding whenever I see fit I want my code to execute fast (thus the elegant approaches and refactoring) This bothers me because I see my colleagues doing much better the other way around (aside from the fact that they started programming since our first year in college). By the other way around I mean, they fire up coding, gets the job done much faster because they don't have to really look at how clean their codes are or how elegant their algorithms are, they don't bother with OOP however big their projects are, they mostly use web APIs, piece them together and voila! Working code! CLients are happy, they get paid fast, at the expense of a really unmaintainable or hard-to-read code that lacks structure and conventions, or slow executions of certain actions (which the common reasoning against would be that internet connections are much faster these days, hardware is more powerful). The excuse I often receive is clients don't care about how you write the code, but they do care about how long you deliver it. If it works then all is good. Now, did my "purist" approach to programming may have been the wrong way to start programming? Should I just dump these purist concepts and just code the hell up because I have seen it: clients don't really care how beautifully coded it is?

  • SEO: Where do I start?

    - by James
    Hi, I am primarily a software developer however I tend to delve in some web development from time to time. I have recently been asked to have a look at a friends website as they are wanting to improve their position in search engine results i.e. google/yahoo etc. I am aware there is no guarentee that their position will change, however, I do know there are techniques/ways to make your website more visible to search engine spiders and to consequently improve your position in the rankings i.e. performing SEO. Before I started looking at the SEO of the site I did the following prerequsite checks: Ran the website through the W3C Markup Validator and the W3C CSS Validator services. Looked through the markup code manually (check for meta tags etc) Performed a thorough cross browser compatibility test. From those checks, the following was evident: No SEO has been performed on the site before. The website has been developed using a visual editing tool such as dreamweaver (as it failed the validation services miserably and tables where being used everywhere!) The site is fairly cross browser compatibile (only some slight issues with IE8 which are easily resolved). How the site navigation is, isn't very search engine friendly (e.g. index.php?page=home) I can see right away a major improvement for SEO (or I at least think) would be to change the way the website is structured i.e. change from using dynamic pages such as "index.php?page=home" and actually having pages called "home.html". Other area's would be to add meta tags to identify keywords, and then sprinkling these keywords over the pages. As I am a rookie in this department, could anyone give me some advice on how I could perform thorough SEO on this website? Thanks in advance.

  • Using JQuery with dynamically added controls (MVC)

    - by Mario
    I have a set of radio buttons that are dynamically generated (via JSON call): StringBuilder sbEligAll = new StringBuilder(); sbEligAll.Append("<div id='currentselectiondepartment'>"); sbEligAll.Append(" <input type='radio' name='selectalldepartment' id='radCurrent' value='0' /><label for='radCurrent'>Current</label>"); sbEligAll.Append(" <input type='radio' name='selectalldepartment' id='radFuture' value='1' /><label for='radFuture'>Future</label>"); sbEligAll.Append(" <input type='radio' name='selectalldepartment' id='radCurrentAll' value='2' /><label for='radCurrentAll'>Current All</label>"); sbEligAll.Append(" <input type='radio' name='selectalldepartment' id='radFutureAll' value='3' /><label for='radFutureAll'>Future All</label>"); sbEligAll.Append("</div>"); Then: return Json(new { TableList = sbElig.ToString() }, JsonRequestBehavior.AllowGet); Is there a way to get jQuery to be able to interact with these? For example: $("input[name=selectalldepartment]").change(function() { var str = $('input[name=selectalldepartment]:checked').val(); $(".radiolist[value='" + str + "']").attr("checked", true); }); I've tried everything I know how to do, but the jQuery just doesnt fire. (I've added alerts to the jQuery code to see if it actually gets called, and it does not). Any thoughts?! Thanks!

  • ASP.Net Problem with Event Handlers and Control Creation Timing

    - by Oliver Weichhold
    What I am trying to achieve here is to display a number of LinkButtons in a RadGrid Column. The buttons are generated from a collection property member of the bound grid row item. The CollectionLinkButton control is nothing more than a asp:Panel derived control that populates its Child Controls from "DataItem.SomeCollection" and this is working fine. The problem I am facing is with this part: Collection='<%# DataBinder.Eval(Container, "DataItem.SomeCollection") %' This is because databound Collection Property is populated so late in the lifecycle of the page that the LinkButton Controls that the CollectionLinkButton class creates from the collection are not available yet during Postback when the Click event Handler is supposed to fire and I have currently no idea how to solve this problem. <radG:RadGrid ID="grid" runat="server" DataSourceID="ds_AB"> <MasterTableView> <Columns> <radG:GridTemplateColumn> <ItemTemplate> <local:CollectionLinkButton ID="LinkButton1" runat="server" CssClass="EntityLinkButton" Collection='<%# DataBinder.Eval(Container, "DataItem.SomeCollection") %>' CollectionProperty="Id" CollectionDisplayProperty="Name" Text='<%# DataBinder.Eval(Container, "DataItem.Name") %>'</local:CollectionLinkButton> </ItemTemplate> </radG:GridTemplateColumn>

  • How to create extensible dynamic array in Java without using pre-made classes?

    - by AndrejaKo
    Yeah, it's a homework question, so givemetehkodezplsthx! :) Anyway, here's what I need to do: I need to have a class which will have among its attributes array of objects of another class. The proper way to do this in my opinion would be to use something like LinkedList, Vector or similar. Unfortunately, last time I did that, I got fire and brimstone from my professor, because according to his belief I was using advanced stuff without understanding basics. Now next obvious solution would be to create array with fixed number of elements and add checks to get and set which will see if the array is full. If it is full, they'd create new bigger array, copy older array's data to the new array and return the new array to the caller. If it's mostly empty, they'd create new smaller array and move data from old array to new. To me this looks a bit stupid. For my homework, there probably won't be more that 3 elements in an array, but I'd like to make a scalable solution without manually calculating statistics about how often is array filled, what is the average number of new elements added, then using results of calculation to calculate number of elements in new array and so on. By the way, there is no need to remove elements from the middle of the array. Any tips?

  • Passing a URL as a URL parameter

    - by Andrea
    I am implementing OpenId login in a CakePHP application. At a certain point, I need to redirect to another action, while preserving the information about the OpenId identity, which is itself a URL (with GET parameters), for instance https://www.google.com/accounts/o8/id?id=31g2iy321i3y1idh43q7tyYgdsjhd863Es How do I pass this data? The first attempt would be function openid() { ... $this->redirect(array('controller' => 'users', 'action' => 'openid_create', $openid)); } but the obvious problem is that this completely messes up the way CakePHP parses URL parameters. I'd need to do either of the following: 1) encode the URL in a CakePHP friendly manner for passing it, and decoding it after that, or 2) pass the URL as a POST parameter but I don't know how to do this. EDIT: In response to comments, I should be more clear. I am using the OpenId component, and I have a working OpenId implementation. What I need to do is to link OpenId with an existing user system. When a new user logs in via OpenId, I ask for more details, and then create a new user with this data. The problem is that I have to keep the OpenId URL throughout this process.

  • compiler directive defensive programming for adding ints to nsmuatablearray FMDB/EGODB

    - by johndpope
    I would like to throw a warning message when users try to add an int to an nsmutablearray basically any insert statement that includes values that are not nsstring / nsnumber cause run time crashes. It's exactly the same crash you get when you type %@ instead of %d NSLog(int); The crash is ok, but I want to throw a friendly 'FATAL' message to user. so far I have this try catch with isKindOfClass NSObject but ints are slipping through. #define FATAL_MSG "FATAL: object is not an NSObject subclass. Are you using int? use [NSNumber numberWithInt:1] \n" #define VAToArray(firstarg) ({\ NSMutableArray* valistArray = [NSMutableArray array];\ id obj = nil;\ va_list arguments;\ va_start(arguments, sql);\ @try { \ while ((obj = va_arg(arguments, id))) {\ if([obj isKindOfClass:[NSObject class]]) [valistArray addObject:obj];\ else printf(FATAL_MSG); \ }\ } \ @catch(NSException *exception){ \ printf(FATAL_MSG); \ } \ va_end(arguments);\ valistArray;\ }) - (void)test:(NSString*)sql,... { NSLog(@"VAToArray :%@",VAToArray(sql)); } // then call this [self test:@"str",@"test",nil]; when I call this [self test:@"str",2,nil]; throw the error message.

  • How to restrict text search to a certain subset of the database ?

    - by Nikhil Garg
    I have a large central database of around 1 million heavy records. In my app, for every user I would have a subset of rows from central table, which would be very small (probably 100 records each).When a particular user has logged in , I would want to search on this data set only. Example: Say I have a central database of all cars in the world. I have a user profile for General Motors(GM) , Ferrari etc. When GM is logged in I just want to search(a full text search and not fire a sql query) for those cars which are manufactured by GM. Also GM may launch/withdraw a model in which case central db would be updated & so would be rowset associated with GM. In case of acquisitions, db of certain profiles may change without launch/removal of new car. So central db wont change then , but rowsets may. Whats the best way to implement such a design ? These smaller row sets would need to be dynamic depending on user activities. We are on Rails 2.3.5 and use thinking_sphinx as the connector and Sphinx/MySQL for search and relational associations.

  • Cannot convert object, recieved from ajax call, into a long

    - by Matt
    I'm using Asp.Net-Mvc, I have this method in my controller: [AcceptVerbs(HttpVerbs.Post)] public ActionResult LinkAccount(string site, object id) { return this.Json(id); } Here's the ajax method that calls it: $.post("/Account/LinkAccount", { site: "Facebook", id: FB.Facebook.apiClient.get_session().uid }, function(result) { alert(result); }, "json" ); returning this.Json(id); makes the alert work... it alerts 7128383 (something similar to that). but if I change this.Json(id) to this.Json(Conver.ToInt64(id)); the alert does not fire... Any idea of why I can't convert an object received from an object to a long? I already know changing the LinkAccount method to accept a long instead works just fine. It's just I need it as an object because some other sites I'm linking up have strings for id's rather than longs. UPDATE: I tried running the code on localhost so I could set a breakpoint. First I changed the line return this.Json(Convert.ToInt64(id)); to long idAsLong = Convert.ToInt64(id));. Here's what the debugger is telling me: When I hover over id it says: "id | {string[1]}" and when I press the plus button is shows: "[0] | '7128383'" When I hover over idAsLong, it says: "idAsLong | 0" Why isn't it converting it properly?

  • What's the best way to learn .NET?

    - by duffymo
    I've been developing Java EE for quite a while now. I've used WebLogic, Tomcat, Spring, and Hibernate extensively, so I have a mental model of what features are available and how things are developed and deployed. The problem that I have with .NET is that I don't have a clear mapping of its features onto Java EE. Here's what I know so far: Java EE - .NET Java - C# JAR - DLL WAR - ? (deployment in general) EAR - ? (deployment in general) Tomcat - IIS web server JSP - ASP? JDBC - ODBC JMS - MSMQ JTA - Microsoft Transaction Manager So much of the functionality that WebLogic handles appears to be dispersed throughout the Windows OS. My confusion kicks in when I see the waves of books at Borders - VB.NET, ASP.NET, C#, etc. If I'm not a VB programmer, would it be possible to stick with C# and write enterprise apps that are the equivalent of what I'm used to with Java EE? If there were a Top Three list of books to learn from, what would they be? The "Head First" series has certainly been successful for Java. http://www.amazon.com/Head-First-C-Brain-Friendly-Guides/dp/0596514824/ref=sr_1_1?ie=UTF8&s=books&qid=1224121193&sr=8-1 Equally well recommended for .NET learning?

  • QT EventTransition implementation

    - by Thomas
    I am trying to build an QT State Maschine. I have some States, and for those States i need Transition that alter the Graphics on my gui. The Problem i having and the only reason i am asking, i am Stuck and Point 1. The compiler cant identifie the QTEventTransition. I have QT 4.6 wroking with QT Creator on Windows. The compiler does not find Header #include < QtEventTransition This is what i did i never did this bevor but i think it should be correct, I have A Header File where i have my Transitions Declareted like this: class validateBoatTransition : public QtEventTransition { public: validateBoatTransition(Widget *widget,ServerSkeleton* server); protected: bool eventTest(QEvent *e); void onTransition(QEvent *); private: Chart* ourChart; Message current; BarelySocket* myBarelySocket; }; Than i have my Cpp File where i have this: validateBoatTransition::validateBoatTransition(Widget *widget,ServerSkeleton* server) { } void validateBoatTransition::onTransition(QEvent *e) { /* My Logik should go here */ } What i want is that if the Transition is activated by an Button (clicked) it should fire this transition! I searched the net, but cant find an solution. Can i do that? I should i think. Yours Thomas

  • Declare module name of classes for logging

    - by Space_C0wb0y
    I currently am adding some features to our logging-library. One of these is the possibility to declare a module-name for a class that automatically gets preprended to any log-messages writing from within that class. However, if no module-name is provided, nothing is prepended. Currently I am using a trait-class that has a static function that returns the name. template< class T > struct ModuleNameTrait { static std::string Value() { return ""; } }; template< > struct ModuleNameTrait< Foo > { static std::string Value() { return "Foo"; } }; This class can be defined using a helper-macro. The drawback is, that the module-name has to be declared outside of the class. I would like this to be possible within the class. Also, I want to be able to remove all logging-code using a preprocessor directive. I know that using SFINAE one can check if a template argument has a certain member, but since other people, that are not as friendly with templates as I am, will have to maintain the code, I am looking for a much simpler solution. If there is none, I will stick with the traits approach. Thanks in advance!

  • NOT A DUPLICATE! VS2010 - How to automatically stop compile on first compile error

    - by Ben Robbins
    {rant}First I'd like to say that this IS NOT A DUPLICATE. I've asked this question previously but it got closed as a duplicate when it isn't. This question is SPECIFIC to VS 2010 and the answers to the so-called duplicate work in VS 2008 but not in VS 2010 (at least not for me or anyone I know). So before you go closing something as a duplicate how about you read the question carefully and try the answer for yourself and see if it actually works. Apologies for the rant but there is no obvious way to contact the SO police that closed the issue or get it reopened. {/rant} At work we have a C# solution with over 80 projects. In VS 2008 we use a macro to stop the compile as soon as a project in the solution fails to build (see this question for several options for VS 2005 & VS 2008: http://stackoverflow.com/questions/134796/how-to-automatically-stop-visual-c-build-at-first-compile-error). Is it possible to do the same in VS 2010? What we have found is that in VS 2010 the macros don't work (at least I couldn't get them to work) as it appears that the environment events don't fire in VS 2010. The default behaviour is to continue as far as possible and display a list of errors in the error window. I'm happy for it to stop either as soon as an error is encountered (file-level) or as soon as a project fails to build (project-level). Answers for VS 2010 only please. If the macros do work then a detailed explanation of how to configure them for VS 2010 would be appreciated. Thanks.

  • Protected and Private methods

    - by cabaret
    I'm reading through Beginning Ruby and I'm stuck at the part about private and protected methods. This is a newbie question, I know. I searched through SO for a bit but I couldn't manage to find a clear and newbie-friendly explanation of the difference between private and protected methods. The book gives two examples, the first one for private methods: class Person def initialize(name) set_name(name) end def name @first_name + ' ' + @last_name end private def set_name(name) first_name, last_name = name.split(/\s+/) set_first_name(first_name) set_last_name(last_name) end def set_first_name(name) @first_name = name end def set_last_name(name) @last_name = name end end In this case, if I try p = Person.new("Fred Bloggs") p.set_last_name("Smith") It will tell me that I can't use the set_last_name method, because it's private. All good till there. However, in the other example, they define an age method as protected and when I do fred = Person.new(34) chris = Person.new(25) puts chris.age_difference_with(fred) puts chris.age It gives an error: :20: protected method 'age' called for #<Person:0x1e5f28 @age=25> (NoMethodError) I honestly fail to see the difference between the private and protected methods, it sounds the same to me. Could someone provide me with a clear explanation so I'll never get confused about this again? I'll provide the code for the second example if necessary.

  • Minimal deployment of couchdb on windows

    - by MartinStettner
    Hi, I'd like to use couchdb for a client-only application on Windows (the document-oriented structure and the synchronization features would be perfect for me). There is a Windows installer package here, but the installer itself has about 45 MB, when installed it takes more than 100 MB on my HD. This is far to much for my (relatively small) application. I noticed that there are a lot of "src" directories in the couchdb/lib subdirs. I've been experimenting with removing some of them and it didn't seem to break the system. Now I'm wondering what would be the "minimal" set of files (preferably binary-only) that would be needed in order to run a local couchdb server. Are there already any efforts to create such a deployment-friendly installer? Or could anyone give some (even very general) hints how to create it? How much disk space would be minimally required for such an installation? Needless to say that I'm not at all familiar with neither the couchdb internals nor the Erlang system :). But perhaps I could figure out if I got some direction (or I could stop trying if someone told me that this would be impossible or didn't make sense at all ...) Thanks anyway!

  • How to use Data aware controls "correctly"?

    - by lyborko
    Hi, I would like to ask experienced users, if you prefer to use data aware controls to add, insert, delete and edit data in DB or you favor to do it manualy. I developed some DB applications, in which for the sake of "user friendly policy" I run into complicated web of table events (afterinsert, afteredit, after... and beforeedit, beforeinsert, before...). After that it was a quite nasty work to debug the application. Aware of this risk (later by another application) I tried to avoid this problem, so I paid increased attention to write code well, readable and comprehensive. It seemed everything all right from the beginning, but as I needed to handle some preprocessing stuff before sending and loading data etc, I run into the same problems again, "slowly and inevitably". Sometime I could not use dataaware controls anyway, and what seemed to be a "cool" feature of DAControl at the beginning it turned to an obstacle on the end. I "had to" write special routine for non-dataaware controls, in order to behave as dataaware. Then I asked myself, why on earth should I use dataaware controls? Is it better to found application architecture on non-dataaware controls? It requires more time to write bug-proof code, of course, but does it worth of it? I do not know... I happened to me several times, like jinxed : paradise on the beginning hell on the end... I do not know, if I use wrong method to write DB program, if there is some standard common practice how to proceed. Or if it is common problem to everybody? Thanx for advices and your experiences

  • Batch faulting in a to-many relationship for a collection of objects

    - by indragie
    Scenario: Let's say I have an entity called Author that has a to-many relationship called books to the Book entity (inverse relationship author). If I have an existing collection of Author objects, I want to fault in the books relationship for all of them in a single fetch request. Code This is what I've tried so far: NSArray *authors = ... // array of `Author` objects NSFetchRequest *fetchRequest = [NSFetchRequest fetchRequestWithEntityName:@"Book"]; fetchRequest.returnsObjectsAsFaults = NO; fetchRequest.predicate = [NSPredicate predicateWithFormat:@"author IN %@", authors]; Executing this fetch request does not result in the books relationship of the objects in the authors array being faulted in (inspected via logging). I've also tried doing the fetch request the other way around: NSArray *authors = ... // array of `Author` objects NSFetchRequest *fetchRequest = [NSFetchRequest fetchRequestWithEntityName:@"Author"]; fetchRequest.returnsObjectsAsFaults = NO; fetchRequest.predicate = [NSPredicate predicateWithFormat:@"SELF IN %@", authors]; fetchRequest.relationshipKeypathsForPrefetching = @[@"books"]; This doesn't fire the faults either. What's the appropriate way of going about doing this?

  • Javascript onclick stops working, multiple dynamically created divs.

    - by Patrick
    I have run into a strange problem, i am creating a lot of dynamically divs. And i recently found out that some of my divs doesn't fire the onclick event? All the divs are created using the same template, so why are some not working? Most of the time, its the 4-5 from the bottom. If you click on one of the others and then try again, you might get one of those to trigger. But only sporadically. Code to create the divs: GameField.prototype.InitField = function(fieldNumber) { var newField = document.createElement("div"); if (fieldNumber == 0 || fieldNumber == 6 || fieldNumber == 8 || fieldNumber == 17) newField.className = 'gameCellSmall borderFull gameText gameTextAlign'; else newField.className = 'gameCellSmall borderWithoutTop gameText gameTextAlign'; var instance = this; if (fieldNumber == 6 || fieldNumber == 7 || fieldNumber == 17) { } else newField.onclick = function() { instance.DivClick(fieldNumber); return false; } this.fields[fieldNumber] = newField; this.score[fieldNumber] = 0; return newField; } I added the return false to the click function, but it still behaves strangely. Why are some not triggering? I create around 18 divs / player. But it happens even if i just create one player. Do i perhaps need to cancel the event once i am done with it? (Like the return false; is trying to do)

  • Windows.Forms RichTextBox Control - Avoid inserting large data.

    - by SchlaWiener
    I have a Windows Form with a RichTextBox on it. The content of the RichTextBox is written to a database field that ist limited to 64k data. For my purpose that is way more than enough text to store. I have set the MaxLength property to avoid insertng more data than allowed. rtcControl.MaxLength = 65536 Howevery, that only restricts the amount of characters that so is allowed to put in the text. But with the formatting overhead from the Rtf I can type more text than I should be allowed to. It even get's worse if I insert a large image, which dosn't increase the TextLength at all but the Rtf Length grows quite a lot. At the moment I check the Length of the richttextboxes' Rtf property in the FormClosing event and display a message to the user if it's to large. However that is just a workaround because I want to disallow putting more data than allowed into the control (like in a textbox if you exceed the MaxLength property nothing is inserted into the control and you hear the default beep(). Any ideas how to achive this? I already tried: using a custom control which extends the richtextbox and shadows th Rtf property to intercept the insertation. But it seems it isn't executed if I add text. Even the TextChanged Event does not fire if I type smth. in the control.

    - by gre3ns0ul
    Hi guys, i'm with one strange problem. I am extending a control from a Gridview, and adding a dropdown to paging to the page i want. In my custom gridview i added a ITemplate than contains 4 image buttons and one dropdownlist (4 images - 1st, prev, next, last) (1 ddl - to page) and add him to my custom gridview.. I added a selectindexchange event to dropdown, to fire when a index is changed The problem is: The first time i load the page with my control it is really ok.. but when i change index, in debug i see to run constructor of control, creating footer template, and guess.. the method of indexchange isn't fired and returns an exception saying: Unable to cast object of type 'System.Web.UI.WebControls.ImageButton' to type 'System.Web.UI.WebControls.Table'.

  • Flex: Menubar, menu click

    - by javanes
    I do not know why but I see that itemclick event on a menubar do not fired unless you click a sub item. What is the clean way to handle clicks on menuitems which are on the top level and do not have sub menu items. For example I want to fire an event whenever MenuItem B is clicked. <?xml version="1.0"?> <!-- menus/MenuBarControl.mxml --> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" > <mx:MenuBar id="myMenuBar" labelField="@label" itemClick="{itemClick(event)}" > <mx:XMLList> <menuitem label="MenuItem A"> <menuitem label="SubMenuItem A-1"/> <menuitem label="SubMenuItem A-2"/> </menuitem> <menuitem label="MenuItem B"/> </mx:XMLList> </mx:MenuBar> </mx:Application>
