  • HTML Input on change of value

    - by arik-so
    Hello, I have an input tag. This tag does not have the autocomplete feature turned off, thus, one does not necessarily need to release a key to change the value of this field and focus anotehr one. My question is: how can I detect ANY value changes of this particular field, like e. g. <input onvaluechange="//do following..." /> The JavaScritp attribute onchange does not fire on change of value, only on changes like blur, focus, etc... Thanks in advance!

  • PASS Summit Feedback

    - by Rob Farley
    PASS Feedback came in last week. I also saw my dentist for some fillings... At the PASS Summit this year, I delivered a couple of regular sessions and a Lightning Talk. People told me they enjoyed it, but when the rankings came out, they showed that I didn’t score particularly well. Brent Ozar was keen to discuss it with me. Brent: PASS speaker feedback is out. You did two sessions and a Lightning Talk. How did you go? Rob: Not so well actually, thanks for asking. Brent: Ha! Sorry. Of course you know that's why I wanted to discuss this with you. I was in one of your sessions at SQLBits in the UK a month before PASS, and I thought you rocked. You've got a really good and distinctive delivery style.  Then I noticed your talks were ranked in the bottom quarter of the Summit ratings and wanted to discuss it. Rob: Yeah, I know. You did ask me if we could do this...  I should explain – my presentation style is not the stereotypical IT conference one. I throw in jokes, and try to engage the audience thoroughly. I find many talks amazingly dry, and I guess I try to buck that trend. I also run training courses, and find that I get a lot of feedback from people thanking me for keeping things interesting. That said, I also get feedback criticising me for my style, and that’s basically what’s happened here. For the rest of this discussion, let’s focus on my talk about the Incredible Shrinking Execution Plan, which I considered to be my main talk. Brent: I thought that session title was the very best one at the entire Summit, and I had it on my recommended sessions list.  In four words, you managed to sum up the topic and your sense of humor.  I read that and immediately thought, "People need to be in this session," and then it didn't score well.  Tell me about your scores. Rob: The questions on the feedback form covered the usefulness of the information, the speaker’s presentation skills, their knowledge of the subject, how well the session was described, the amount of time allocated, and the quality of the presentation materials. Brent: Presentation materials? But you don’t do slides.  Did they rate your thong? Rob: No-one saw my flip-flops in this talk, Brent. I created a script in Management Studio, and published that afterwards, but I think people will have scored that question based on the lack of slides. I wasn’t expecting to do particularly well on that one. That was the only section that didn’t have 5/5 as the most popular score. Brent: See, that sucks, because cookbook-style scripts are often some of my favorites.  Adam Machanic's Service Broker workbench series helped me immensely when I was prepping for the MCM.  As an attendee, I'd rather have a commented script than a slide deck.  So how did you rank so low? Rob: When I look at the scores that you got (based on your blog post), you got very few scores below 3 – people that felt strong enough about your talk to post a negative score. In my scores, between 5% and 10% were below 3 (except on the question about whether I knew my stuff – I guess I came as knowledgeable). Brent: Wow – so quite a few people really didn’t like your talk then? Rob: Yeah. Mind you, based on the comments, some people really loved it. I’d like to think that there would be a certain portion of the room who may have rated the talk as one of the best of the conference. Some of my comments included “amazing!”, “Best presentation so far!”, “Wow, best session yet”, “fantastic” and “Outstanding!”. I think lots of talks can be “Great”, but not so many talks can be “Outstanding” without the word losing its meaning. One wrote “Pretty amazing presentation, considering it was completely extemporaneous.” Brent: Extemporaneous, eh? Rob: Yeah. I guess they don’t realise how much preparation goes into coming across as unprepared. In many ways it’s much easier to give a written speech than to deliver a presentation without slides as a prompt. Brent: That delivery style, the really relaxed, casual, college-professor approach was one of the things I really liked about your presentation at SQLbits.  As somebody who presents a lot, I "get" it - I know how hard it is to come off as relaxed and comfortable with your own material.  It's like improv done by jazz players and comedians - if you've never tried it, you don't realize how hard it is.  People also don't realize how hard it is to make a tough subject fun. Rob: Yeah well... There will be people writing comments on this post that say I wasn't trying to make the subject fun, and that I was making it all about me. Sometimes the style works, sometimes it doesn't. Most of the comments mentioned the fact that I tell jokes, some in a nice way, but some not so much (and it wasn't just a PASS thing - that's the mix of feedback I generally get). One comment at PASS was: “great stand up comedian - not what I'm looking for at pass”, and there were certainly a few that said “too many jokes”. I’m not trying to do stand-up – jokes are my way of engaging with the audience while I demonstrate some of the amazing things that the Query Optimizer can do if you write your queries the right way. Some people didn’t think it was technical enough, but I’ve also had some people tell me that the concepts I’m explaining are deep and profound. Brent: To me, that's a hallmark of a great explanation - when someone says, "But of course it has to work that way - how could it work any other way?  It seems so simple and logical."  Well, sure it does when it's explained correctly, but now pick up any number of thick SQL Server books and try to understand the Redundant Joins concept.  I guarantee it'll take more than 45 minutes. Rob: Some people in my audiences realise that, but definitely not everyone. There's only so much you can tell someone that something is profound. Generally it's something that they either have an epiphany on or not. I like to lull my audience into knowing what's going on, and do something that surprises them. Gain their trust, build a rapport, and then show them the deeper truth of what just happened. Brent: So you've learned your lesson about presentation scores, right?  From here on out, you're going to be dry, humorless, and all your presentations will consist of you reading bullet points off the screen. Rob: No Brent, I’m not. I'm also not going to suggest that most presentations at PASS are like that. No-one tries to present like that. There's a big space to occupy between what "dry and humourless" and me. My difference is to focus on the relationship I have with the crowd, rather than focussing on delivering the perfect session. I want to see people smiling and know they're relaxed. I think most presenters focus on the material, which is completely reasonable and safe. I remember once hearing someone talking about product creation. They talked about mediocrity. They said that one of the worst things that people can ever say about your product is that it’s “good”. What you want is for 10% of the world to love it enough to want to buy it. If 10% the world gave me a dollar, I’d have more money than I could ever use (assuming it wasn’t the SAME dollar they were giving me I guess). Brent: It's the Raving Fans theory.  It's better to have a small number of raving customers than a large number of almost-but-not-really customers who don't care that much about your product or service.  I know exactly how you feel - when I got survey feedback from my Quest video presentation when I was dressed up in a Richard Simmons costume, some of the attendees said I was unprofessional and distracting.  Some of the attendees couldn't get enough and Photoshopped all kinds of stuff into the screen captures.  On a whole, I probably didn't score that well, and I'm fine with that.  It sucks to look at the scores though - do those lower scores bother you? Rob: Of course they do. It hurts deeply. I open myself up and give presentations in a very personal way. All presenters do that, and we all feel the pain of negative feedback. I hate coming 146th & 162nd out of 185, but have to acknowledge that many sessions did worse still. Plus, once I feel the wounds have healed, I’ll be able to remember that there are people in the world that rave about my presentation style, and figure that people will hopefully talk about me. One day maybe those people that don’t like my presentation style will stay away and I might be able to score better. You don’t pay to hear country music if you prefer western... Lots of people find chili too spicy, but it’s still a popular food. Brent: But don’t you want to appeal to everyone? Rob: I do, but I don’t want to be lukewarm as in Revelation 3:16. I’d rather disgust and be discussed. Well, maybe not ‘disgust’, but I don’t want to conform. Conformity just isn’t the same any more. I’m not sure I’ve ever been one to do that. I try not to offend, but definitely like to be different. Brent: Count me among your raving fans, sir.  Where can we see you next? Rob: Considering I live in Adelaide in Australia, I’m not about to appear at anyone’s local SQL Saturday. I’m still trying to plan which events I’ll get to in 2011. I’ve submitted abstracts for TechEd North America, but won’t hold my breath. I’m also considering the SQLBits conferences in the UK in April, PASS in October, and I’m sure I’ll do some LiveMeeting presentations for user groups. Online, people download some of my recent SQLBits presentations at http://bit.ly/RFSarg and http://bit.ly/Simplification though. And they can download a 5-minute MP3 of my Lightning Talk at http://www.lobsterpot.com.au/files/Collation.mp3, in which I try to explain the idea behind collation, using thongs as an example. Brent: I was in the audience for http://bit.ly/RFSarg. That was a great presentation. Rob: Thanks, Brent. Now where’s my dollar?

  • Where is the value of OEA

    - by [email protected]
    In a room full of architects, if you were to ask for the definition of enterprise architecture, or the importance thereof,  you are likely to get a number of varying view points ranging from,  a complete analysis of the digital assets of an organization,  to, a strategic alignment of business goals/objectives to IT initiatives.  Similiarily in a room full of senior business executives,  if you asked them how they see their IT groups and their effectiveness to align to business strategy,  you would get a myriad of responses,  ranging from, “a huge drain on our bottom line”, “always more expensive than budgeted”, “lack of agility,  by the time IT is ready,  my business strategy has changed”, and on the rare occurrence, “ a leader of innovation,  that is lock step with my business strategy”. However does this necessarily demonstrate the overall value of enterprise architecture.  Having a framework, and process is of critical importance to help produce a number of the artefacts that ultimately align technology goals and initiatives to business strategy,  however,  is that really where the value is?  I believe that first we need to understand the concept of valueValue typically is a measure of sorts,  when we purchase a product it’s value is equivalent to the maximum amount that someone is willing to pay for the product,  however,  is the same equation valid in terms of the business value of enterprise architecture? Is the library of artefacts generated through a process/framework, inclusive of a strategic roadmap to realize the enterprise architecture where the value is? If we agree that enterprise architecture is the alignment of IT and IT assets to support business strategy, and by achieving our business strategy, we have we have increased the business value of the enterprise then;  it seems that, in order to really identify the true value of an enterprise architecture,  we need to understand how we measure business value .  A number of formal measurement methodologies exist for this purpose, business models, balanced scorecards, etc   After we have an understanding on how to measure the business value of each of the organizational units within an enterprise, then we understand how the enterprise architecture contributes to the success of business strategy,  and EXECUTE on the roadmap to implement, and deliver the IT initiatives that provide MEASUREABLE returns, As we analyse the value chain of each of the individual organizational units within the enterprise we may identify how that unit has performed by quantitatively measuring it proximity to achieving the goals defined by the business for each unit. However, It would appear that true business value (the aggregate of all of the business units in the value chain), is to some degree subjectively measured  as for public companies this lies in shareholder value,  as the true value, or be it, the maximum amount that someone would pay for shares of an organization.

  • 24 Hours of PASS: Whine, Whine, Whine

    - by Most Valuable Yak (Rob Volk)
    24 Hours of Pass (or 24HOP) is a great program offered by PASS to provide free, online training for anyone who wants to learn more about SQL Server.  They routinely have the best SQL Server presenters available for these sessions, and attract hundreds, perhaps even a thousand attendees from around the world.  This is definitely one of the best things they've started doing in the past few years, and every session I've attended has been excellent. So why am I so grumpy about it? I'm not really, pretty much everything here is a minor annoyance that I can deal with.  However since they're so minor they seem to be things that can be easily corrected and would make the process much better. First off, this is my biggest gripe, the registration page: https://www323.livemeeting.com/lrs/8000181573/Registration.aspx?pageName=lj6378f4fhf5hpdm What grinds my gears about this?  I have to scroll alllllllllllllllllllllllllllll the way to bottom to actually register for the sessions.  This wouldn't be so bad except all the details of the session, including the presenter, is in a separate list at the top.  Both lists contain info the other does not, and scrolling between them to determine "Should I make time to listen to this?  Who is speaking at this time anyway?" is really unnecessary. My preference would be to keep the top list and add the checkboxes and schedule info in separate columns.  This is a full-width design, so there's plenty of space for this data, which is pretty small anyway.  The other huge benefit is halving the size of the page, which improves performance and lowers bandwidth usage considerably.  And if you know HTML/ASP.Net, and you view the page source, you can find PLENTY of other things that can be reduced even further.  (not just viewstate) One nice thing that PASS does is send iCal reminders to your email address so you can accept them to your calendar.  Again, they leave off the presenter in the appointment details, while still duplicating the meeting title in the body.  Sometimes I make decisions based on speaker rather than content (Natalie Portman is reading the Yellow Pages??? I'M THERE!) and having the speaker in the iCal is helpful. Next minor annoyances are the necessity for providing a company name, and the survey questions.  I know PASS needs to market themselves effectively, and they need information to do that, and since this is a free event it's really not worth complaining about, but why ask the survey question twice? (once at registration, once again when joining the LiveMeeting)  Same thing for the company name.  All of this should be tied to email address, so that's all I should need to enter when joining the LiveMeeting. The last one is also minor, but it irks me in this day and age of multiple browsers and the decline of Internet Explorer as a dominant platform.  The registration page was originally created in Visual Studio 2003, and has a lot of IE-specific crud representative of the browser situation of 2003. (IE5 references? really? and is the aforementioned viewstate big enough?)  This causes some grief with other browsers like Firefox, Chrome, and sometimes IE8 or 9.  And don't get me started on using the page on a Mac or in Safari. My main point is that PASS is an international organization, welcoming everyone from all levels of SQL Server proficiency, and in that spirit I think it would help to accommodate a wider range of browser software, especially since the registration page is extremely simple.  I recognize that this page is not hosted on the PASS website and may be maintained by some division of Microsoft, but to me that's even worse if MS can't update their own pages.  They've deprecated IE6, so they don't need to maintain support on their own websites anymore. OK, I'll shut up now. #sqlpass #24HOP

  • Powerbuilder : How to compare the old value and new value of a column in data window

    - by Archangel
    Suppose I have a datawindow object which is attached to a datawindow control named 'dw_detail". This object uses grid presentation style and has a database column named 'found'. Now when a user modifies that column's value, I want to compare it with the original value that was fetched from the database. I know I can access the value of that column as 'dw_detail.object.found[row_no]'. Now I am trying to access the original value of the column as 'dw_detail.object.found.original[row_no]', but it is not working. It is not giving any compiling error, but when I debugged, 'dw_detail.object.found.original[row_no]' contains no values. How can I access the original value of that column?

  • Observing an NSMutableArray for insertion/removal

    - by Adam Ernst
    A class has a property (and instance var) of type NSMutableArray with synthesized accessors (via @property). If you observe this array using: [myObj addObserver:self forKeyPath:@"theArray" options:0 context:NULL]; And then insert an object in the array like this: [[myObj theArray] addObject:[NSString string]]; An observeValueForKeyPath... notification is not sent. However, the following does send the proper notification: [[myObj mutableArrayValueForKey:@"theArray"] addObject:[NSString string]]; This is because mutableArrayValueForKey returns a proxy object that takes care of notifying observers. But shouldn't the synthesized accessors automatically return such a proxy object? What's the proper way to work around this--should I write a custom accessor that just invokes [super mutableArrayValueForKey...]?

  • Returning object from function

    - by brainydexter
    I am really confused now on how and which method to use to return object from a function. I want some feedback on the solutions for the given requirements. Scenario A: The returned object is to be stored in a variable which need not be modified during its lifetime. Thus, const Foo SomeClass::GetFoo() { return Foo(); } invoked as: someMethod() { const Foo& l_Foo = someClassPInstance->GetFoo(); //... } Scneraio B: The returned object is to be stored in a variable which will be modified during its lifetime. Thus, void SomeClass::GetFoo(Foo& a_Foo_ref) { a_Foo_ref = Foo(); } invoked as: someMethod() { Foo l_Foo; someClassPInstance-GetFoo(l_Foo); //... } I have one question here: Lets say that Foo cannot have a default constructor. Then how would you deal with that in this situation, since we cant write this anymore: Foo l_Foo Scenario C: Foo SomeClass::GetFoo() { return Foo(); } invoked as: someMethod() { Foo l_Foo = someClassPInstance->GetFoo(); //... } I think this is not the recommended approach since it would incur constructing extra temporaries. What do you think ? Also, do you recommend a better way to handle this instead ?
