• Flex AdvancedDataGrid with Grouping, how do I get objects to appear under first GroupingField if the

  - by shadenite

  I am using an AdvancedDataGrid with two GroupingFields. The dataProvider has a list of objects with these two field values, but occasionally the second field value can be null. When it loads, the AdvancedDataGrid UI has a root folder (first GroupingField) and some additional subfolders (second GroupingField). This is all good. However, the objects with a null value for the second GroupingField, just get placed in a subfolder with no label. I want the objects with a null second GroupingField value to appear as leaf nodes beneath the root folder (first GroupingField) minus the blank subfolder. A good way to picture this would be a file explorer. Is there a good way to do this? Make the folder icon disappear maybe after expanding this node through actionscript? ParentFolder SubFolder Leaf Object Leaf Object SubFolder Leaf Object Leaf Object Leaf Object

• How to "chain" modal dialogs in YUI 2 ?

  - by giulio

  I have a modal dialog box presented in Yahoo UI. The user selects a value from dialog "A", and then I want to present another modal dialog box to collect some more data in dialog "B". I have been using the YAHOO.widget.Dialog successfully. The problem seems to be that you can't initiate dialog window "B" from the handler function of dialog "A". So, how can you programmatically launch a second dialog window after the user hits the "OK" button on the first ? (I had tried to create an additional Listener for a field that is updated in dialog "A" to trigger dialog "B" but this doesn't work either.) Thanks..

• How can I schedule tasks in a WinForms app?

  - by Greg

  QUESTION: How can I schedule tasks in a WinForms app? That is either (a) what is the best approach / .NET classes/methods to use of (b) if there is an open source component that does this well which one would be recommended. BACKGROUND: Winforms app (.NET v3.5, C#, VS2008) I'm assuming I will run the winforms application always, and just minimise to the system tray when not in use Want a simple approach (didn't want to get into separate service running that UI winforms app talks to etc) Want to be able to let the user select how often to schedule the sync (e.g. hourly, daily - pick time, etc) Ability to at the times when the scheduler fires to run a chunk of code (assume it could be wrapped as a backgroundworker task for example) The application is always running & appears in the system tray

• What makes MVVM uniquely suited to WPF?

  - by Reed Copsey

  The Model-View-ViewModel is very popular with WPF and Silverlight. I've been using this for my most recent projects, and am a very large fan. I understand that it's a refinement of MVP. However, I am wondering exactly what unique characteristics of WPF (and Silverlight) allow MVVM to work, and prevent (or at least make difficult) this pattern from working using other frameworks or technologies. I know MVVM has a strong dependency on the powerful data binding technology within WPF. This is the one feature which many articles and blogs seem to mention as being the key to WPF providing the means of the strong separation of View from ViewModel. However, data binding exists in many forms in other UI frameworks. There are even projects like Truss that provide WPF-style databinding to POCO in .NET. What features, other than data binding, make WPF and Silverlight uniquely suited to Model-View-ViewModel?

• jquery tooltip over dialog

  - by alemjerus

  I have a simple html multiline tooltip implementation: this.tooltip = function(tag) { xOffset = 10; yOffset = 20; $(tag + ".tooltip").hover(function(e){ this.t = this.title; this.title = ""; $("body").append("<p id='tooltip'>"+ this.t +"</p>"); $("#tooltip") .css("top",(e.pageY - xOffset) + "px") .css("left",(e.pageX + yOffset) + "px") .fadeIn("fast"); }, function(){ this.title = this.t; $("#tooltip").remove(); }); $(tag + ".tooltip").mousemove(function(e){ $("#tooltip") .css("top",(e.pageY - xOffset) + "px") .css("left",(e.pageX + yOffset) + "px"); }); }; It works perfectly on a page, but does not display a thing over jquery.ui.dialog. Is there a way to fix that?

• as3 loops and event listeners

  - by Ross

  I have an array that returns multidimensional data from an mysql database, when this is collected the createNews function creates the user interface. The problem I am having is the loop is iterating quicker than the ui is being created, is there a way to use event listeners with loops so it only continues after my function has completed its work. Any solutions or ideas are much appreciated; Thanks, R. var t:Array = responds.serverInfo.initialData; for (var i:uint = 0; i < t.length; i++) { var date = t[i][1]; var newstitle = t[i][2]; var story= t[i][3]; var image = t[i][4]; createNews(date, newstitle, story, image); }

• PowerBuilder Indeterminate Progress Bar

  - by Adam Hawkes

  I have a somewhat-long-running stored procedure being called from a PB application. I want the UI to show an indicator that it is processing, but I don't know the exact progress. That is, I can't say whether it is 10% or 90% done. All I know is when it is done. To give the user something to look at I'd like to put a "Inderterminate" (horizontal) progress bar on the window somewhere. I've looked at the documentation for the built-in HProgressBar control and don't see how to force this behavior. Short of writing my own control or importing another one, is there a way to accomplish this?

• Check if thread is EDT is necessary?

  - by YuppieNetworking

  Hello, I have an UI implemented with Swing. One component does some work that may take some time, so I use SwingUtilities.invokeLater. However, I was reading some old code and found this in an ActionListener: if (!SwingUtilities.isEventDispatchThread()) { SwingUtilities.invokeLater(new Runnable() { public void run() { // code X } }); } else { // code X } I thought that it made sense since it separates code X from the EDT. However, I found it error-prone since I have used it a couple of times and both times I forgot the else part. The question is: is the SwingUtilities.isEventDispatchThread() checking necessary? Or could I assume that I am not in the EDT and always use invokeLater? Thanks a lot.

• Reverse-engineer a Javascript object?

  - by TruMan1

  I have a Javascript object that I want to pass in more parameters, but the documentation is non-existant. My only option seems to be to reverse engineer the Javascript object to see what parameters and values I can pass in. For example, I want to see if there is a "zoom" parameter for the object and what values I can pass into the "mapType" parameter: <script type="text/javascript" src="http://maps.google.com/maps?oe=utf-8&amp;file=api&amp;v=2&amp;key=your-gmap-key"></script> <script type="text/javascript" src="https://share.findmespot.com/spot-widget/js/SpotMain.js"></script> <script type="text/javascript"> var widget = new Spot.Ui.LiveWidget({ renderTo: "spot-live-widget", feeds: [ "0Wl3diTJcqqvncI6NNsoqJV5ygrFtQfBB" ], height: 400, width: 500, mapType: "physical" }); </script> <div id="spot-live-widget"/> Any ideas on how to do that?

• Code reviews for larger MVC.NET team using TFS

  - by Parrots

  I'm trying to find a good code review workflow for my team. Most questions similar to this on SO revolve around using shelved changes for the review, however I'm curious about how this works for people with larger teams. We usually have 2-3 people working a story (UI person, Domain/Repository person, sometimes DB person). I've recommended the shelf idea but we're all concerned about how to manage that with multiple people working the same feature. How could you share a shelf between multiple programmers at that point? We worry it would be clunky and we might easily have unintended consequences moving to this workflow. Of course moving to shelfs for each feature avoids having 10 or so checkins per feature (as developers need to share code) making seeing the diffs at code review time painful. Has anyone else been able to successfully deal with this? Are there any tools out there people have found useful aside from shelfs in TFS (preferably open-source)?

• How to create migration in subdirectory with Rails?

  - by Adrian Serafin

  Hi! I'm writing SaaS model application. My application database consist of two logic parts: application tables - such as user, roles... user defined tables (he can generate them from ui level) that can be different for each application instance All tables are created by rails migrations mechanism. I would like to put user defined tables in another directory: db/migrations - application tables db/migrations/custom - tables generated by user so i can do svn:ignore on db/migrations/custom, and when I do updates of my app on clients servers it would only update application tables migrations. Is there any way to achieve this in rails?

• Software to create a knowledge base/FAQ system

  - by H1Man

  Our company is looking to build a web-based knowledge base system that can be used by our clients/end users to reduce the amount of support calls. Couple important notes: This is aimed at our end users, in other words, non-techies. So the UI has to be easy to use Should have the excellent (fast, accurate) search Should have ability to rate and comment on articles This will only be maintained by one or 2 people, so security isn't a big concern Something similar to what Microsoft is doing with their Knowledge Base. http://support.microsoft.com/search/ Does anyone have any recommendations on what software I can use? Thanks, H. Edit: I should have made this clear before but I don't mean build as in having our developers build a support/kb system from the ground up. I am looking to use a existing software package/solution that can be used to implement a knowledge base/support site.

• Returning the value of an identity column during/after INSERT command

  - by Adam Kane

  Using VS 2010, with ASP.NET, and .NET 3.0, and C#... When I use a System.Web.UI.WebControls.SqlDataSource and call its Insert() method to insert a new row, and that table has an identity column, I'd like my method to return the value of that column. For example, in my SQL 2005 table, I've got: Customer.Id Customer.FirstName Customer.LastName Where Customer.Id is an identity colum. When I call my method InsertNewCustomerRecord( "John", "Smith" ), I'd like to be able to return the Customer.Id that gets automatically generated in the database. Sorry for such a roughly posed question. Let me know if I can add better detail. Thanks.

• Javascript draw dynamic line

  - by Ranch

  Hello, I'm looking for Javascript code for letting the user draw a line (on an image). Just as the line tool in Photoshop (for example): The user clicks on the image, drags the mouse (while the line between the start point and the mouse point is dynamically drawn on mouse drag). I would also need a callable function to send the page the start and end coordinates. I've found this very nice script for area selection: http://www.defusion.org.uk/code/javascript-image-cropper-ui-using-prototype-scriptaculous/ and I've found many script for drawing lines (and other shapes in JS), but could not find what I'm looking for. Thanks

• How to check for an existing executable before running it in a post-build event in VS2008?

  - by wtaniguchi

  Hey all, I'm trying to use SubWCRev to get the current revision number of our SVN repository and put it in a file so I can show it in the UI. As I'm working with a Web App, I use the following post build command line: "SubWCRev.exe" "$(SolutionDir)." "$(ProjectDir)Content\js\revnumber.js.tpl" "$(ProjectDir)Content\js\revnumber.js" It works great, but now I want to make sure I have SubWCRev before running it, so I can skip this post build if a fellow developer is not running TortoiseSVN. I tried a few batch codes here, but couldn't figure this out. Any ideas? Thanks!

• Accessing WebKit Devtools JavaScript library

  - by VLostBoy

  I noticed something in Chrome the other day- I had opened Developer Tools, and then hit view source and was initially surprised to notice that apparently the developer tools window is coded in HTML and JavaScript- you can see that by putting the following into the Chrome address bar: view-source:chrome://devtools/devtools.html Two things struck me- first, the codes copyright belongs to Apple (considering their backing of WebKit, thats not too surprising), and secondly, it appears that you cannot access the JavaScript, CSS or Image files directly through Chrome by clicking on links in the source code. So two questions: Where are the DevTools assets stored on my computer or how can I otherwise access them? Or even better, can someone identify the library that is used and let me know how its licensed? I'm always on the look out for a well implemented UI toolkit- and Devtools looks great.

• So how I can control the page contents loading sequence in dojo

  - by David Zhao

  Hi there, I'm using dojo for our UI's, and would like to load certain part of page contents in sequence. For example, for a certain stock, I'd like to load stock general information, such as ticker, company name, key stats, etc. and a grid with the last 30 days open/close prices. Different contents will be fetched from the server separately. Now, I'd like first load the grid so the user can have something to look at, then, say, start loading of key stats which is a large data set takes longer time to load. How do I do this. I tried: dojo.addOnLoad(function() { startGrid(); //mock grid startup function which works fine getKeyStats(); //mock key stat getter function also works fine }); But dojo is loading getKeyStats(), then startGrid() here for some reason, and sequence doesn't seem be matter here. So how I can control the loading sequence at will? Thanks in advance! David

• NSInteger differences between CLI and GUI ?

  - by d11wtq

  I've been building a framework and writing unit tests in GHUnit. One of my Framework's accessor methods returns an NSInteger. I assert the expected value in the tests like this: GHAssertEquals(1320, request.port, @"Port number should be 1320"); When running my tests with an AppKit UI based frontend this assertion passes. However, when I run my tests on the command line, it fails with a type-mismatch unless I type-cast my hard-coded 1320 as (NSInteger). What's causing the difference in the way the integer is being interpreted by the compiler? Is xcodebuild on the command line using a different data-type for hard coded integers?

• How to call WCF Service Method Asycroniously from Class file?

  - by stackuser1

  I've added WCF Service reference to my asp.net application and configured that reference to support asncronious calls. From asp.net code behind files, i'm able to call the service methods asyncroniously like the bellow sample code. protected void Button1_Click(object sender, EventArgs e) { PageAsyncTask pat = new PageAsyncTask(BeiginGetDataAsync, EndDataRetrieveAsync, null, null); Page.RegisterAsyncTask(pat); } IAsyncResult BeiginGetDataAsync(object sender, EventArgs e, AsyncCallback async, object extractData) { svc = new Service1Client(); return svc.BeginGetData(656,async, extractData); } void EndDataRetrieveAsync(IAsyncResult ar) { Label1.Text = svc.EndGetData(ar); } and in page directive added Async="true" In this scenario it is working fine. But from UI i'm not supposed to call the service methods directly. I need to call all service methods from a static class and from code behind file i need to invoke the static method. In this scenario what exactlly do i need to do?
