• FLEX: customized tag Cloud, how to compute positioning and distances

  - by Patrick

  hi, I want to build a tag cloud like this one in my Flex application. See image: http://dl.dropbox.com/u/72686/tagCloud.png At the moment I have the tags (that are mx.controls.LinkButtons) added at the same position and having different sizes according to values (stored in an ArrayComponent). In my visualization, the orange tags are supposed to be listed vertically in the middle. The gray tags should be at different distances (according to stored numeric values). I want to avoid overlapping and cluttering. How do you suggest to compute x and y of the gray tags taking care about: the distances from orange tags avoid overlapping between them thanks

• Best practice for conditional output in ASP.NET MVC?

  - by RyanW

  I'm ramping up on ASP.NET MVC and looking at how I output messages in the view. What's the best way to do something like this? Helpers? Controls? Or just as is? <% if (ViewData.ContainsKey("message") && !string.IsNullOrEmpty(ViewData["message"].ToString())) { %> <div class="notice"> <%= ViewData["message"] %> </div> <% } %>

• Attachment_fu file saving problem

  - by Anand

  Attachment_fu plugin is kind of old, but I have to modify an old app and I can't use another plugin like paperclip etc. So here's the code without further ado Submissions table structure --------------------------- | content_type | varchar(255) | YES | | NULL | filename | varchar(255) | YES | | NULL app/models/submission.rb ------------------------ has_attachment :storage => :file_system, :path_prefix => 'public/submissions', :max_size => 2.megabytes, :content_type => ['application/pdf', 'application/msword', 'text/plain'] app/models/user.rb ------------------ has_one :submission, :dependent => :destroy app/views/user/some_action.html.erb ----------------------------------- <% form_for :user, :url => { :action => "some_action" }, :html => {:multipart => true} do |f| %> .... <%= file_field_tag "submission[uploaded_data]" %> <%end%> app/controllers/user_controller.rb ---------------------------------- @user = User.find_user(session[:user_id]) @submission = @user.submission if request.post? @submission.uploaded_data = params[:submission][:uploaded_data] end When the form is submitted, the database fields "content_type" and "filename" get updated and display the correct values, but the file does not appear in public/submissions/ directory. I have checked the permissions on the submissions directory. What am I missing? Many Thanks

• ASP.NET - ViewState: empty placeholder generates view state

  - by Budda

  On my web-page I have PlaceHolder, not controls are loaded into it. <asp:PlaceHolder ID="PlaceHolderStatMain" runat="server"> </asp:PlaceHolder> I am looking the ViewState generated for the page, it is the following: <input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="/wEPDwUJLTg1NDkyNTUzD2QWAgIDD2QWAgIND2QWAmYPZBYCAgEPZBYCZg9kFgJmD2QWBmYPFQEYL3N0YXRfc3RhZGl1bS9sZWFndWVfV0VGZAIBDxUBGC9zdGF0X3N0YWRpdW0vbGVhZ3VlX0VFRmQCAg8VARgvc3RhdF9zdGFkaXVtL2xlYWd1ZV9GQ1VkZEuSBUr5LFL6WfCehNBJgjrq0GzwWCWN2qlU70V7LAAb" /> When I set EnableViewState to false: <asp:PlaceHolder ID="PlaceHolderStatMain" runat="server" EnableViewState="false"> </asp:PlaceHolder> The viewstate content was decreased significantly: <input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="/wEPDwUJLTg1NDkyNTUzZGTTn8Y28VwmpE/K7yPPkLFvhrqMdU8THijFW/BMFzk0tQ==" /> Question: how to remove 'useless' viewstate content without disabling viewstate for placeholder himself (I would like other control loaded into placeholder to has viewstate)? Is it possible at all? Any thought are welcome! P.S. I am using ASP.NET 4.0

• BindData to ITemplate for GridView in code behind

  - by tbischel

  How do I programmatically bind data to a custom item template column for a GridView? So far, I've done something similar to this: TemplateField foo = new TemplateField(); foo.ItemTemplate = new bar(); this.GridView1.Columns.Add(foo); where bar is like this: public class bar : ITemplate { public bar() { } public void InstantiateIn(Control container) { DropDownList ddl = new DropDownList(); container.Controls.Add(ddl); } } (the actual dropdownlist is populated) But ITemplate doesn't contain any kind of data binding properties to implement, and the TemplateField class doesn't seem to have any either... What do I do?

• In JSF - What is the correct way to do this? Two dropdown lists with dependency.

  - by Ben

  Hi, I'm making two dropdown lists in JSF which are dependent. Specifically, one list has all the languages and the second list contains values that are displayed in the currently selected language. I've implemented this by having the second list use information from a Hash and rebuilding that Hash in the setter of the currently selected language. JSF Code Bit: <rich:dropDownMenu value="#{bean.currentlySelectedLanguage}" id="languageSelector"> ... (binding to languages hash) ... <rich:dropDownMenu value="#{bean.currentlySelectedScript}" id="ScriptPullDown"> ... (binding to scripts hash) ... Backing Bean Code Bit: setCurrentlySelectedLanguage(String lang){ this.currentlySelectedLanguage = lang; rebuildScriptNames(lang); } I'm wondering if that's a good way of doing this or if theres a better method that I am not aware of. Thank you! EDIT - Adding info.. I used a a4j:support that with event="onchange" and ReRender="ScriptPullDown" to rerender the script pull down. I could probably add an action expression to run a method when the value changes. But is there a benefit to doing this over using code in the setter function?

• Silverlight Scrollable Content Problem

  - by Steve

  I am fairy new to Silverlight and I have a problem. I have a grid on a page that is resizable when the user resizes their browser window. In one of the grids columns I want to display dynamically added content that is scrollable, as there is more data than space available. I currently have a scrollViewer with a stack panel inside it, that i programmatically add a user control to and then several user controls to that control depending on the amount of content. My problem is this. The scrollViewer does not respect the available space and as such displays its content outside of the viewable area when there is more data than space. i.e. it does not uses it is not scrollable nature. Hopefully this is something simple that I have missed, but i am banging my head against the wall at the moment. Any help gratefully received.

• How to debug and detect hang issue

  - by igor

  I am testing my application (Windows 7, WinForms, Infragistics controls, C#, .Net 3.5). I have two monitors and my application saves and restores forms' position on the first or second monitors. So I physically switched off second monitor and disabled it at Screen Resolution on the windows display settings form. I need to know it is possible for my application to restore windows positions (for those windows that were saved on the second monitor) to the first one. I switched off second monitor and press Detect to apply hardware changes. Then Windows switched OFF the first monitor for a few seconds to apply new settings. When the first monitor screen came back, my application became unresponsive. My application was launched in debug mode, so I tried to navigate via stack and threads (Visual Studio 2008), paused application, started and did not find any thing that help me to understand why my application is not responsive. Could somebody help my how to detect the source of issue.

• Use of 'this keyword' javascript in IE ?

  - by Ron

  Is there a workaround for Internet Explorer to implement the functionality offered by 'this' javascript keyword to get the dom element that triggered the event? My problem scenario is : I have a variable number of text fields in the html form, like input type="text" id="11" input type="text" id="12" .. I need to handle the "onchange" event for each text field, and the handling is dependent on the 'id' of the field that triggered the event. So far I understand that my options are: 1) attach a dedicated event handler for each text field. so if I have n fields, i have n different functions, something like: input type="text" id="11" onchange="function11();" input type="text" id="12" onchange="function12();" but the text fields are added and removed dynamically, so a better way would be to have one generic function instead. 2) use the 'this' keyword like: input type="text" id="11" onchange="functionGeneric(this);" input type="text" id="12" onchange="functionGeneric(this);" But this option does not work with Internet Explorer. Can anyone suggest a work around for getting it work in IE or some other solution that can be applied here? Thanks.

  - by TGuimond

  Hi Guys, I am developing a multi-lingual website. I am determining the requested language via a querystring variable eg: http://mydomain.com/default.aspx?lang=en I am using two <asp:LoginStatus /> controls in my masterpage. My web.config file is set up like this for forms authentication. <authentication mode="Forms"> <forms loginUrl="~/login.aspx" protection="All" timeout="30" name=".ASPXAUTH" path="/" requireSSL="false" slidingExpiration="true" defaultUrl="default.aspx" cookieless="UseDeviceProfile" enableCrossAppRedirects="false"/> </authentication> Currently when you click on a <asp:LoginStatus /> you will be redirected to my login page and the url will look something like this: http://mydomain.com/login.aspx?ReturnUrl=%2fdefault.aspx%3flang%3den What solutions are available to me so that I can append my lang variable to my login.aspx? depending on which language is currently active?

• How to find out who's causing an access violation error?

  - by Fernando

  I'm getting reports that my app is causing a GPF on some Vista machines. The error message is something like this: access violation at 0x75784062 ( tried to write to 0x00000006) In order to fix this, I first need to know exactly who is causing this GPF: my main exe, some third party component, one of my own activex components, a dll, etc... How can I find this out? What tools can pinpoint the exact module that caused this mess? Any help would be greatly appreciated. PS My app is coded in VB6 and my activex controls are written in Delphi 2007.

• What's the best practice to setup testing for ASP.Net MVC? What to use/process/etc?

  - by melaos

  hi there, i'm trying to learn how to properly setup testing for an ASP.Net MVC. and from what i've been reading here and there thus far, the definition of legacy code kind of piques my interests, where it mentions that legacy codes are any codes without unit tests. so i did my project in a hurry not having the time to properly setup unit tests for the app and i'm still learning how to properly do TDD and unit testing at the same time. then i came upon selenium IDE/RC and was using it to test on the browser end. it was during that time too that i came upon the concept of integration testing, so from my understanding it seems that unit testing should be done to define the test and basic assumptions of each function, and if the function is dependent on something else, that something else needs to be mocked so that the tests is always singular and can be run fast. Questions: so am i right to say that the project should have started with unit test with proper mocks using something like rhino mocks. then anything else which requires 3rd party dll, database data access etc to be done via integration testing using selenium? because i have a function which calls a third party dll, i'm not sure whether to write a unit test in nunit to just instantiate the object and pass it some dummy data which breaks the mocking part to test it or just cover that part in my selenium integration testing when i submit my forms and call the dll. and for user acceptance tests, is it safe to say we can just use selenium again? Am i missing something or is there a better way/framework? i'm trying to put in more tests for regression testing, and to ensure that nothing breaks when we put in new features. i also like the idea of TDD because it helps to better define the function, sort of like a meta documentation. thanks!! hope this question isn't too subjective because i need it for my case.

• Controlling PowerPoint Slideshow

  - by Jayesh

  Hi, I have a scenario: There is a Slideshow running in PowerPoint. I want to control the movement [Next and Previous] of the slides. Of course it is possible with the [ and < button on the keyboard], but is there any way in which I can have a custom application listening to the Next and Previous controls? As in, my custom application has nothing but 2 buttons, next and previous, when I click either, the button's event handler should pass the control to the Power Point Application running the slideshow. And thus, the powerpoint will move the slideshow back or forward? Somewhat similar to the way remote, wireless Power Point Presenters work on the s/w end. Thank You.

• How would I go about building a calendar UI control for the iPhone/iPad?

  - by BeachRunnerJoe

  Hello. There are a few different 3rd party code frameworks that include calendar controls, but most of them have a lot of functionality I don't need, plus most of them lack sufficient documentation on how to use them and I'm not a proficient enough iPhone developer figure it out using just the code. So I'm going to attempt to build my own and I was hoping you could provide me with some high-level direction to get started. At a high level, how could I build a simple, calendar control that doesn't do much more than display a calendar (month view, with the current date highlighted) and allows the user to selected a date? Something that looks like the calendar in the upper right corner of this image... Thanks so much in advance for your help!

• Asymptotic runtime of list-to-tree function

  - by Deestan

  I have a merge function which takes time O(log n) to combine two trees into one, and a listToTree function which converts an initial list of elements to singleton trees and repeatedly calls merge on each successive pair of trees until only one tree remains. Function signatures and relevant implementations are as follows: merge :: Tree a -> Tree a -> Tree a --// O(log n) where n is size of input trees singleton :: a -> Tree a --// O(1) empty :: Tree a --// O(1) listToTree :: [a] -> Tree a --// Supposedly O(n) listToTree = listToTreeR . (map singleton) listToTreeR :: [Tree a] -> Tree a listToTreeR [] = empty listToTreeR (x:[]) = x listToTreeR xs = listToTreeR (mergePairs xs) mergePairs :: [Tree a] -> [Tree a] mergePairs [] = [] mergePairs (x:[]) = [x] mergePairs (x:y:xs) = merge x y : mergePairs xs This is a slightly simplified version of exercise 3.3 in Purely Functional Data Structures by Chris Okasaki. According to the exercise, I shall now show that listToTree takes O(n) time. Which I can't. :-( There are trivially ceil(log n) recursive calls to listToTreeR, meaning ceil(log n) calls to mergePairs. The running time of mergePairs is dependent on the length of the list, and the sizes of the trees. The length of the list is 2^h-1, and the sizes of the trees are log(n/(2^h)), where h=log n is the first recursive step, and h=1 is the last recursive step. Each call to mergePairs thus takes time (2^h-1) * log(n/(2^h)) I'm having trouble taking this analysis any further. Can anyone give me a hint in the right direction?

• JQuery and IE8 - Form posting on tab change

  - by Tommy

  This issue is only happening in IE8 - Firefox 3.5 seems to handle it fine. I have JQuery UI tabs setup on a page. Within each tab is a form that users can do stuff from. I have defined in the select option of the using: $("#tabs").tabs({select: function(event, ui) {...}}); a submitForm function that submits the form of the tab the user was on previous to changing tabs. This all works in all browsers. The issue comes in that IE does both the POST of the form on the previous tab and the GET for content of the newly requested tab and or really close to the same time (from what I can tell walking through the debugger). As a result, if a tab is dependent on the form input from another tab, the data is stale - does not match the user input from the previous tab. How can I either a) force the POST to complete before rendering the next tab or b) force IE to not make the POST and GET for the next tab at the same time?...or c) some other option?

• Show different sub-sets of a view model's properties in an edit view

  - by Martin R-L

  In the context of C# 4, ASP.NET MVC 2, and NHibernate; I've got the following scenario: Let's assume an entity Product that have an association to ProductType. In a product edit view; how do I implement that only a sub-set of the product's properties are shown based on the ProductType association in an elegant and DRY way? I.e., different properties shall be shown for different values of a property of the ProductType. Use a product view model builder, and from different view models automagically generate the view with my own Html.EditorForModel() (including drop-downs and other stuff not out-of-the-box)? Attribute the properties of one view model and use the Html.EditorForModel() way aforementioned? Use one model, but implement different web controls (view strategies) (can it be done DRY?)? Something else entirely?

• ways to avoid global temp tables in oracle

  - by Omnipresent

  We just converted our sql server stored procedures to oracle procedures. Sql Server SP's were highly dependent on session tables (INSERT INTO #table1...) these tables got converted as global temporary tables in oracle. We ended up with aroun 500 GTT's for our 400 SP's Now we are finding out that working with GTT's in oracle is considered a last option because of performance and other issues. what other alternatives are there? Collections? Cursors? Our typical use of GTT's is like so: Insert into GTT INSERT INTO some_gtt_1 (column_a, column_b, column_c) (SELECT someA, someB, someC FROM TABLE_A WHERE condition_1 = 'YN756' AND type_cd = 'P' AND TO_NUMBER(TO_CHAR(m_date, 'MM')) = '12' AND (lname LIKE (v_LnameUpper || '%') OR lname LIKE (v_searchLnameLower || '%')) AND (e_flag = 'Y' OR it_flag = 'Y' OR fit_flag = 'Y')); Update the GTT UPDATE some_gtt_1 a SET column_a = (SELECT b.data_a FROM some_table_b b WHERE a.column_b = b.data_b AND a.column_c = 'C') WHERE column_a IS NULL OR column_a = ' '; and later on get the data out of the GTT. These are just sample queries, in actuality the queries are really complext with lot of joins and subqueries. I have a three part question: Can someone show how to transform the above sample queries to collections and/or cursors? Since with GTT's you can work natively with SQL...why go away from the GTTs? are they really that bad. What should be the guidelines on When to use and When to avoid GTT's

• How should the View pull on the Presenter in the MVP pattern

  - by John Leidegren

  I have a ASP.NET Web Forms application and I'm using some dynamic controls in the view which depend on stuff that the presenter exposes. Is it okay for the view in this case to pull on the presenter for that data? Is there anything I should be extra careful about when considering testability and a loosely coupled design. The page in this case has it's own page-life cycle and the presenter doesn't know about this. However, the page-life cycle dictates that somethings must occur at specific moments in the page-life cycle. This smells like trouble... Any known pit falls?

• NSTask executed only once

  - by Eimantas

  I'm having trouble executing different NSTask's. Same launchPath, different arguments. I have a class who's instances administer own NSTask objects and depending on arguments those instances were initialized with - dependent NSTask object is being created. I have two initializers: // Method for finished task - (void)taskFinished:(NSNotification *)aNotification { [myTask release]; myTask = nil; [self createTask]; } // Designated initializer - (id) init { self = [super init]; if (self != nil) { [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(taskFinished:) name:NSTaskDidTerminateNotification object:nil]; [self createTask]; } return self; } // Convenience initializer - (id)initWithCommand:(NSString *)subCommand { self = [self init]; if (self) { [self setCommand:subCommand]; } return self; } And here 's the createTask method: - (void)createTask { // myTask is a property defined as NSTask* myTask = [[NSTask alloc] init]; [myTask setLaunchPath:@"/usr/bin/executable"]; } Say I have 3 buttons. Each one creates different class instance with different NSTask objects. But problem is that only first one gets executed. The second ones does not even triger "click" event (via target-action). I think it could be cause of launchPath I'm trying to use, 'cause simple /bin/ls works fine. The same command in terminal has 0 return value (i.e. all is fine). Any guides or gotchas are much appreciated.

• How do you keep yourself and your co-workers from creating huge classes

  - by PieterG

  Stackoverflow users, How do you keep yourself from creating large classes with large bodied methods. When deadlines are tight, you end up trying to hack things together and it ends up being a mess which would need to be refactored. For me, the one way was to start with test driven development and that lends itself to good class design as well as the SRP (Single Responsibility Principle). I also see developers just double clicking on controls and typing out line after line in the event method that gets fired. What are your suggestions?

• MySql left join on several regs

  Hi there! I have this table1 idproduct(PK) | date_to_go 1 2010-01-18 2 2010-02-01 3 2010-02-21 4 2010-02-03 and this other table2 that controls date_to_go updates id | idproduct(FK) | prev_date_to_go | date_to_go | update_date 1 1 2010-01-01 2010-01-05 2009-12-01 2 1 2010-01-05 2010-01-10 2009-12-20 3 1 2010-01-10 2010-01-18 2009-12-20 4 3 2010-01-20 2010-02-03 2010-01-05 So, in this example, for table1.idproduct #1 2010-01-18 is the actual date_to_go and 2010-01-01 (table2.prev_date_to_go, first reg) is the original date_to_go . using this query select v.idproduct, v.date_to_go, p.prev_date_to_go original_date_to_go from table1 v left join produto_datas p on p.idproduto = v.idproduto group by (v.idproduto) order by v.idproduto can I assume that original_date_to_go will be the first related reg of table2? idproduct | date_to_go | original_date_to_go 1 2010-01-18 2010-01-01 2 2010-02-01 NULL 3 2010-02-21 2010-01-20 4 2010-02-03 NULL

• BitShifting with BigIntegers in Java

  - by ThePinkPoo

  I am implementing DES Encryption in Java with use of BigIntegers. I am left shifting binary keys with Java BigIntegers by doing the BigInteger.leftShift(int n) method. Key of N (Kn) is dependent on the result of the shift of Kn-1. The problem I am getting is that I am printing out the results after each key is generated and the shifting is not the expected out put. The key is split in 2 Cn and Dn (left and right respectively). I am specifically attempting this: "To do a left shift, move each bit one place to the left, except for the first bit, which is cycled to the end of the block. " It seems to tack on O's on the end depending on the shift. Not sure how to go about correcting this.
