  • Order of calls to set functions when invoking a flex component

    - by Jason
    I have a component called a TableDataViewer that contains the following pieces of data and their associated set functions: [Bindable] private var _dataSetLoader:DataSetLoader; public function get dataSetLoader():DataSetLoader {return _dataSetLoader;} public function set dataSetLoader(dataSetLoader:DataSetLoader):void { trace("setting dSL"); _dataSetLoader = dataSetLoader; } [Bindable] private var _table:Table = null; public function set table(table:Table):void { trace("setting table"); _table = table; _dataSetLoader.load(_table.definition.id, "viewData", _table.definition.id); } This component is nested in another component as follows: <ve:TableDataViewer width="100%" height="100%" paddingTop="10" dataSetLoader="{_openTable.dataSetLoader}" table="{_openTable.table}"/> Looking at the trace in the logs, the call to set table is coming before the call to set dataSetLoader. Which is a real shame because set table() needs dataSetLoader to already be set in order to call its load() function. So my question is, is there a way to enforce an order on the calls to the set functions when declaring a component?

  • C# listbox,params

    - by Oyeme
    As Andrew Hare suggested in his answer: Create a field to store all the ListBox instances and then change the constructor to accept an arbitrary number of them: by I tried the following class scaner { readonly IEnumerable<ListBox> listBoxes; public IEnumerable<ListBox> ListBoxes { get { return this.listBoxes; } } public scaner(params ListBox[] listBoxes) { this.listBoxes = listBoxes; } } This will allow you to do this: scaner Comp = new scaner(listBox1, listBox2); How can i access listbox1? In class scaner i'm trying to call this.listBoxes. (I need to call the listbox1 in scaner class.How can i do/call it? Thanks for answers.

  • All Targets Not Being Called (nested Targets not being executed)

    - by obautista
    I am using a two TARGET files. On one TARGET file I call a TARGET that is inside the second TARGET file. This second TARGET then calls another TARGET that has 6 other TARGET calls, which do a number of different things (in addition to calling other nested TARGETS (but inside the same TARGET file)). The problem is that, on the TARGET where I call 6 TARGETS, only the first one is being executed. The program doesnt find its way to call the 2nd, 3rd, 4th, 5th, and 6th TARGET. Is there a limit to the number of nested TARGETS that can be called and run? Nothing is failing. The problem is the other TARGET calls are not running. Thanks for any help you can provide.

  • What is the difference between a constructor and a procedure in Delphi records?

    - by HMcG
    Is there difference in behavior between a constructor call and a procedure call in Delphi records? I have a D2010 code sample I want to convert to D2009 (which I am using). The sample uses a parameterless constructor, which is not permitted in Delphi 2009. If I substitute a simple parameterless procedure call, is there any functional difference for records? I.E. TVector = record private FImpl: IVector; public constructor Create; // not allowed in D2009 end; becomes TVector = record private FImpl: IVector; public procedure Create; // so change to procedure end; As far as I can see this should work, but I may be missing something.

  • PASS: SQLRally Thoughts

    - by Bill Graziano
    The PASS Board recently decided that we wouldn’t put another US-based SQLRally on the calendar until we had a chance to review the program. I wanted to provide some of my thinking around this. Keep in mind that this is the opinion of one Board member. The Board committed to complete two SQLRally events to determine if an event modeled between SQL Saturday and the Summit was viable. We’ve completed the two events and now it’s time to step back and review the program. This is my seventh year on the PASS Board. Over that time people have asked me why PASS does certain things. Many, many times my answer has been “Because that’s the way we did it last year”. And I am tired of giving that answer. We need to take a step back and review the US-based SQLRally before we schedule another one. It would be irresponsible for me as a Board member to commit resources to this without validating that what we’re doing makes sense for the organization and our members. I have no doubt that this was a great event for the attendees. We just need to validate it’s the best use of our resources. Please keep in mind that we haven’t cancelled the event. We’ve just said we need to review it before scheduling another one. My opinion is that some fairly serious changes are needed to the model before we consider it again – IF we do it again. I’ve come to that conclusion after speaking with the Dallas organizers, our HQ team, our Marketing team, other Board members (including one of the Orlando organizers), attendees in Orlando and Dallas and visiting other similar events. I should point out that their views aren’t unanimous on nearly any part of this event -- which is one of the reasons I want to take some time and think about this before continuing. I think it’s helpful to look at the original goals of what we were trying to accomplish. Andy Warren wrote these up in August of 2010. My summary of these goals and some thoughts on each one is below. Many of these thoughts revolve around the growth of SQL Saturdays. In the two years since that document was written these events have grown significantly. The largest SQL Saturdays are now over 500 people which mean they are nearly the same size as our recent SQLRally. Our goals included: Geographic diversity. We wanted an event in an area of the country that was away from any given Summit location. I think that’s still a valid goal. But we also have SQL Saturdays all over the country. What does SQLRally bring to this that SQLSaturday doesn’t? Speaker growth. One of the stated goals was to build a “farm club” for speakers. This gives us a way for speakers to work up to speaking at Summit by speaking in front of larger crowds. What does SQLRally bring to this that the larger SQL Saturdays aren’t providing? Pre-Conference speakers is one obvious answer here. Lower price. On a per-day basis, SQLRally is roughly 1/4th the price of the Summit. We wanted a way for people to experience something Summit-like at a lower price point. The challenge is that we are very budget constrained at that lower price point. International Event Model.  (I need to write more about this but I’m out of time.  I’ll cover it in the next installment.) There are a number of things I really like about SQLRally. I love the smaller conferences. They give me a chance to meet more people than at something the size of Summit. I like the two day format. That gives you two evenings to be at social events with people. Seeing someone a second day is a great way to build a bond with that person. That’s more difficult to do at a SQL Saturday. We also need to talk about the financial aspects of the event. Last year generated a small $17,000 profit on revenues of $200,000. Percentage-wise that’s reasonable but on an absolute basis it’s not a huge amount in our budget. We think this year will lose between $30,000 and $50,000 and take roughly 1,000 hours of HQ time. We don’t have detailed financials back yet but that’s our best guess at this point. Part of that was driven by using a convention center instead of a hotel. Until we get detailed financials back we won’t have the full picture around the financial impact. This event also takes time and mindshare from our Marketing team. This may sound like a small thing but please don’t underestimate it. Our original vision for this was something that would take very little time from our Marketing team and just a few mentions in the Connector. It turned out to need more than that. And all those mentions and emails take up space we could use to talk about other events and other programs. Last I wanted to talk about some of the things I’m thinking about. I don’t think it’s as simple as saying if we just fix “X” it all gets better. Is this that much better of an event than SQL Saturdays? What if we gave a few SQL Saturdays some extra resources? When SQL Saturdays were around 250 people that wasn’t as viable. With some of those events over 500 we need to reconsider this. We need to get back to a hotel venue. That will help with cost and networking. Is this the best use of the 1,000 HQ hours that we invested in the event? Is our price-point correct? I’m leaning toward raising our price closer to Summit on a per-day basis. I think this will let us put on a higher quality event and alleviate much of the budget pressure. Should growing speakers be a focus? Having top-line pre-conference speakers helps market the event. It will also have an impact on pricing and overall profit. We should also ask if it actually does grow speakers. How many of these people will eventually register for Summit? Attend chapters? Is SQLRally a driver into PASS or is it something that chapters, etc. drive people to? Should we have one paid day and one free instead of two paid days? This is a very interesting model that is used by SQLBits in the UK. This gives you the two day aspect as well as offering options for paid and free attendees. I’m very intrigued by this. Should we focus on a topic? Buried in the minutes is a discussion of whether PASS should have a Business Analytics conference separate from Summit. This is an interesting question to consider. Would making SQLRally be focused on a particular topic make it more attractive? Would that even be a SQLRally? Can PASS effectively manage the two events? (FYI - Probably not.) Would it help differentiate it from Summit and SQL Saturday? These are all questions that I think should be asked and answered before we do this event again. And we can’t do that if we don’t take time to have the discussion. I wanted to get this published before I take off for a few days of vacation. When I get back I’d like to write more about why the international events are different and talk about where we go from here.

  • Programmatically selecting file in explorer

    - by flashk
    In my application I can programmatically open explorer and select a file using the following code: void BrowseToFile(LPCTSTR filename) { CString strArgs; strArgs = _T("/select,\""); strArgs += filename; strArgs += _T("\""); ShellExecute(0, _T("open"), _T("explorer.exe"), strArgs, 0, SW_NORMAL); } My problem is that if I call this function a second time with a different file, but in the same folder, the selection in explorer does not change to the new file, but remains on the previous file. For example, if I call my function with C:\path\to\file1.txt, a new explorer window will open and file1.txt will be selected. If I call my function a second time with C:\path\to\file2.txt, the existing explorer window will be activated, but the selection will still be on file1.txt. Is there a way to force explorer to update the selection or a better way to accomplish this?

  • GKSession sendDataToAllPeers including sendee?

    - by Typeoneerror
    I've got a number of devices connected over wifi using GameKit. I have a simple UIAlertView popping up when peers receive data. All but the sendee show this alert view when data is sent, so I'm wondering if that's a bug in my app or if that's expected behavior. Should call a method manually at the same on the sendee device? For example, if I wanted to send a "GameStart" packet to the 4 phones, the peers would call startGame: in the receiveData:fromPeer:inSession:context: method when it receives that packet and the sendee would just sendData and call startGame: on itself. Does that sound right or is there a way to include the sendee in the sendData list so that it responds exactly the same as all connected peers?

  • Hack Fest Going Strong!

    - by Yolande Poirier
    Today was the first day of  the Hack Fest at Devoxx, the Java developer conference in Belgium.  The Hack Fest started with the Raspberry Pi & Leap Motion hands-on lab. Vinicius Senger introduced the Java Embedded, Arduino and Raspberry Pi. Java Champion Geert Bevin presented the Leap Motion, a controller sensing your hands and fingers to play games by controlling the mouse as an example. "Programmers are cooler than musicians because they can create entire universe using all senses" explained Geert In teams, participants started building applications using Raspberry Pi, sensors and relays. One team tested the performance of Tomcat, Java EE and Java Embedded Suite on the Raspberry Pi. Another used built an text animation using a LCD screen. Teams are using the Leap Motion to close and open programs on the desktop and other teams are using it as a game control.

  • Reusing datasource

    - by nubby
    I'm tying to use one database call and reuse that data for other controls - without having to do another call. Scenario: I call the books table which returns all the authors and titles. I create an author's list control called list1 to displays all the titles by Shakespeare and a list2 to display titles by Charles Dickens. Void Bindme() { string commandText = "Select * from books"; SqlCommand mycommand = new SqlCommand(commandText, datasource1); datasource1.Open(); SqlDataReader myReader1 = mycommand.ExecuteReader(); list1.DataSource = myReader1; list1.DataBind(); list2.DataSource = myReader1; list2.DataBind(); datasource1.Close(); } In my example only the first bind to the source, list1, gets data. Any ideas?

    Here's another article pointing out our move to Java Embedded Middleware with our launch of Oracle Java Embedded Suite 7.0 See: Oracle moves to Java embedded middleware Here's a quote: At the JavaOne Embedded conference, a wafer thin embedded device that was smaller than a Ritz cracker was loaded up with the Java Embedded Suite. I like that: "a wafer thin embedded device". Just one thin wafer. Reminds me of the scene from Monty Python's, The Meaning of Life. "Better?" Hinkmond

  • How can I detect 'any' ajax request being completed using jQuery?

    - by Brian Scott
    I have a page where I can insert some javascript / jquery to manipulate the output. I don't have any other control over the page markup etc. I need to add an extra element via jquery after each present on the page. The issue is that the elements are generated via an asynchronous call on the existing page which occurs after $(document).ready is complete. Essentially, I need a way of calling my jquery after the page has loaded and the subsequent ajax calls have completed. Is there a way to detect the completion of any ajax call on the page and then call my own custom function to insert the additional elements after the newly created s ?

  • Refer to te current directory in a shell script

    - by One Two Three
    How do I refer to the current directory in a shell script So I have this script which calls another script in the same directory #! /bin/sh #Call the other script ./foo.sh # do something ... For this I got ./foo.sh: No such file or directory So I changed it to: #! /bin/sh #Call the other script foo.sh # do something ... But this would call the foo script which is, by default, in the PATH. This is not what I want. So the question is, what's the syntax of doing './` in a shell script?

  • Handling missing/incomplete data in R

    - by doug
    As you would expect from a DSL aimed at data analysts, R handles missing/incomplete data very well, for instance: Many R functions have an 'na.rm' flag that you can set to 'T' to remove the NAs, but if you want to deal with this before the function call, then: to replace each 'NA' w/ 0: ifelse(is.na(vx), 0, vx) to remove each 'NA': vx = vx[!is.na(a)] to remove entire each row that contains 'NA' from a data frame: dfx = dfx[complete.cases(dfx),] All of these functions remove 'NA' or rows with an 'NA' in them. Sometimes this isn't quite what you want though--making an 'NA'-excised copy of the data frame might be necessary for the next step in the workflow but in subsequent steps you often want those rows back (e.g., to calculate a column-wise statistic for a column that has missing rows caused by a prior call to 'complete cases' yet that column has no 'NA' values in it). to be as clear as possible about what i'm looking for: python/numpy has a class, 'masked array', with a 'mask' method, which lets you conceal--but not remove--NAs during a function call. Is there an analogous function in R?

  • problems with extended classes and overwrite with methods

    - by Marco
    I have a .net website written in C# and will make functionalities that other developers can use. So i will make some default implementation and a developer can overwrite some methods Example: i have a class ShoppingCart and a class Product the class product haves a method getProductPrice the shoppingcart will call the method getProductPrice for calculating the total price of cart The Shoppingcart and Product are in the same project and i will give the developers the .dll so they can't change the source code so we can update the assembly later So they need to make a other project and extend the product class and overwrite the method getProductPrice so they can implement there own logic The problem is that the shoppingcart will not call the extended method but the original If we make already a extended project for the developers and the shoppingcart will call the extended method then we have a circular reference because the extended product needs a reference to product and the shopping cart to the extended product partial classes also don't works because we only can use partials within the same assembly anyone a suggestion ? thanks in advance
