  • Custom HTMLControl derived from HtmlImage control not visible in VS2008 toolbox

    - by Tinvan
    I have a custom control deriving from HtmlImage control which I cant get to show up on toolbox, it says "There are no components in '...\bin\Debug\ImageCustomControl.dll' that can be placed on the toolbox.". Here is the code for the control: namespace ImageCustomControl { public class ImageHtmlControl : HtmlImage { public override void RenderControl(HtmlTextWriter writer) { this.Src = "https://somedomain.com" + this.Src; base.RenderControl(writer); } } } Here is a post back from 2003 that says its not possible, but just wanted to know if it has changed since: http://www.microsoft.com/mspress/books/sampchap/5728d.aspx Thanks in advance.

  • Another BC30002: Type is not defined.

    - by brett
    Here's what I've done... I used wsdl.exe to create a .cs class for my wsdl service connection. I made a Visual Studio project to compile the .cs into a dll having namespace CalculatorService (CalculatorService.dll). Successful thus far. I created an asp.net project added my namespace import: %@ Import Namespace="CalculatorService" % I right-clicked on the project, clicked Add Reference, found my .dll, added it, built the project, checked /bin to ensure my dll was there (and it was). % 'I called the namespace:' Dim calcService As New CalculatorService.CalculatorService() 'called the function from the service' Dim xmlResult = calcService.GetSVS_ItemTable_XML("", "", "", "", "", "") 'printed the result' Response.Write(xmlResult) % All is well LOCALLY while debugging. It found the CalculatorService, connected to it, got the XML and displayed it. I then wanted to put it on the web so I built and published my project: under "Copy" - Only files needed to run this application...selected! Deploying on the web says Type 'CalculatorService.CalculatorService' is not defined. Here is a link to the live script: http://vansmith.com/_iaps.wsdl/pub/Default.aspx Any ideas?

  • jquery filter .not()

    - by FFish
    I have a form with image thumbnails to select with checkboxes for downloading. I want an array with the images in jQuery for an Ajax call. 2 questions: - On the top of the table there is a checkbox to toggle all checkboxes that I want to exclude from the mapping. I had a look at jQuery's .not() but I can't implement it with the :checkbox selector - is the following example code correct? $(document).ready(function() { $('#myform').submit(function() { var images = $("input:checkbox", this).map(function() { return $(this).attr("name"); }).get().join(); alert(products); // outputs: ",check1,check2,check3" return false; // cancel submit action by returning false }); }); // end doc ready HTML: <form id="myform" action="" > <input type="checkbox" id="toggleCheck" onclick="toggleSelectAll()" checked="checked" ><br /> <input type="checkbox" name="001.jpg" checked="checked" /><br /> <input type="checkbox" name="002.jpg" checked="checked" /><br /> <input type="checkbox" name="003.jpg" checked="checked" /><br /> <br /> <input type="submit" value="download" > </form>

  • Alternative to sql NOT IN?

    - by Alex
    Hi, I am trying to make a materialized view in Oracle (I am a newbie, btw). For some reason, it doesn't like the presence of sub-query in it. I've been trying to use LEFT OUTER JOIN instead, but it's returning different data set now. Put simply, here's the code I'm trying to modify: SELECT * FROM table1 ros, table2 bal, table3 flx WHERE flx.name = 'XXX' AND flx.value = bal.value AND NVL (ros.ret, 'D') = Nvl (flx.attr16, 'D') AND ros.value = bal.segment3 AND ros.type IN ( 'AL', 'AS', 'PL' ) AND bal.period = 13 AND bal.code NOT IN (SELECT bal1.code FROM table2 bal1 WHERE bal1.value = flx.value AND bal1.segment3 = ros.value AND bal1.flag = bal.flag AND bal1.period = 12 AND bal1.year = bal.year) And here's one of my attempt: SELECT * FROM table1 ros, table2 bal, table3 flx LEFT OUTER JOIN table2 bal1 ON bal.code = bal1.code WHERE bal1.code is null AND bal1.segment3 = ros.value AND bal.segment3 = ros.value AND bal1.flag = bal.flag AND bal1.year = bal.year AND flx.name = 'XXX' AND flx.value = bal.value AND bal1.value = flx.value AND bal1.period_num = 12 AND NVL (ros.type, 'D') = NVL (flx.attr16, 'D') AND ros.value = bal.segment3 AND ros.type IN ( 'AL', 'AS', 'PL' ) AND bal.period = 13; This drives me nuts! Thanks in advance for the help :)

  • NSTimer Reset Not Working

    - by user355900
    hi, i have a nstimer and it works perfectly counting down from 2:00 but when i hit the reset button it does not work it just stops the timer and when i press start again it will carry on with the timer as if it had never been stopped. Here is my code `@implementation TimerAppDelegate @synthesize window; (void)applicationDidFinishLaunching:(UIApplication *)application { timerLabel.text = @"2:00"; seconds = 120; // Override point for customization after application launch [window makeKeyAndVisible]; } (void)viewDidLoad { [timer invalidate]; } (void)countDownOneSecond { seconds--; int currentTime = [timerLabel.text intValue]; int newTime = currentTime - 1; int displaySeconds = !(seconds % 60) ? 0 : seconds < 60 ? seconds : seconds - 60; int displayMinutes = floor(seconds / 60); NSString *time = [NSString stringWithFormat:@"%d:%@%d", displayMinutes, [[NSString stringWithFormat:@"%d", displaySeconds] length] == 1 ? @"0" : @"", displaySeconds ]; timerLabel.text = time; if(seconds == 0) { [timer invalidate]; } } (void)startOrStopTimer { if(timerIsRunning){ [timer invalidate]; [startOrStopButton setTitle:@"Start" forState:UIControlStateNormal]; } else { timer = [[NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(countDownOneSecond) userInfo:nil repeats:YES] retain]; [startOrStopButton setTitle:@"Stop" forState:UIControlStateNormal]; } timerIsRunning = !timerIsRunning; } (void)resetTimer { [timer invalidate]; [startOrStopButton setTitle:@"Start" forState:UIControlStateNormal]; [timer invalidate]; timerLabel.text = @"2:00"; } (void)dealloc { [window release]; [super dealloc]; } @end` thanks

  • jquery hover not working in safari and chrome

    - by Nik
    I'm developing a site and I am implementing a jquery hover effect on some list items. It works perfectly in all browser except safari and chrome (mac and pc). For some reason the hover effect doesnt work on those to browsers. Here is the link link text I thought I would add the code just in case it helps (it also uses the color_library.js file that can be found in the head of the document). $(document).ready(function() { var originalBG = $("#menu li#Q_01","#menu li#Q_03","#menu li#Q_05","#menu li#Q_07","#menu li#Q_09","#menu li#Q_11","#menu li#Q_11").css("background-color"); var originalBG1 = $("#menu li").css("color"); var originalBG2 = $("#menu li#Q_02","#menu li#Q_04","#menu li#Q_06","#menu li#Q_08","#menu li#Q_10","#menu li#Q_12").css("background-color"); var fadeColor = "#009FDD"; var fadeColor1 = "#FFF"; var fadeColor2 = "#623A10"; $("#menu li#Q_01").hover( function () { $(this).animate( { backgroundColor:fadeColor2,color:fadeColor1}, 380 ) }, function () { $(this).animate( {color:"#666",backgroundColor:"#fff"}, 380 ) } ); $("#menu li#Q_03").hover( function () { $(this).animate( { backgroundColor:fadeColor2,color:fadeColor1}, 380 ) }, function () { $(this).animate( {color:"#666",backgroundColor:"#fff"}, 380 ) } ); $("#menu li#Q_05").hover( function () { $(this).animate( { backgroundColor:fadeColor2,color:fadeColor1}, 380 ) }, function () { $(this).animate( {color:"#666",backgroundColor:"#fff"}, 380 ) } ); $("#menu li#Q_07").hover( function () { $(this).animate( { backgroundColor:fadeColor2,color:fadeColor1}, 380 ) }, function () { $(this).animate( {color:"#666",backgroundColor:"#fff"}, 380 ) } ); $("#menu li#Q_09").hover( function () { $(this).animate( { backgroundColor:fadeColor2,color:fadeColor1}, 380 ) }, function () { $(this).animate( {color:"#666",backgroundColor:"#fff"}, 380 ) } ); $("#menu li#Q_11").hover( function () { $(this).animate( { backgroundColor:fadeColor2,color:fadeColor1}, 380 ) }, function () { $(this).animate( {color:"#666",backgroundColor:"#fff"}, 380 ) } ); $("#menu li#Q_13").hover( function () { $(this).animate( { backgroundColor:fadeColor2,color:fadeColor1}, 380 ) }, function () { $(this).animate( {color:"#666",backgroundColor:"#fff"}, 380 ) } ); $("#menu li#Q_02").hover( function () { $(this).animate( { backgroundColor:fadeColor,color:fadeColor1}, 380 ) }, function () { $(this).animate( {color:"#666",backgroundColor:"#fff"}, 380 ) } ); $("#menu li#Q_04").hover( function () { $(this).animate( { backgroundColor:fadeColor,color:fadeColor1}, 380 ) }, function () { $(this).animate( {color:"#666",backgroundColor:"#fff"}, 380 ) } ); $("#menu li#Q_06").hover( function () { $(this).animate( { backgroundColor:fadeColor,color:fadeColor1}, 380 ) }, function () { $(this).animate( {color:"#666",backgroundColor:"#fff"}, 380 ) } ); $("#menu li#Q_08").hover( function () { $(this).animate( { backgroundColor:fadeColor,color:fadeColor1}, 380 ) }, function () { $(this).animate( {color:"#666",backgroundColor:"#fff"}, 380 ) } ); $("#menu li#Q_10").hover( function () { $(this).animate( { backgroundColor:fadeColor,color:fadeColor1}, 380 ) }, function () { $(this).animate( {color:"#666",backgroundColor:"#fff"}, 380 ) } ); $("#menu li#Q_12").hover( function () { $(this).animate( { backgroundColor:fadeColor,color:fadeColor1}, 380 ) }, function () { $(this).animate( {color:"#666",backgroundColor:"#fff"}, 380 ) } ); }); Thanks for any advice ;)

  • codeigniter site, swfobject not fully loading swf

    - by Joe
    I am having a strange problem. I have a view that is supposed to load a swf. The swf was compiled with Flex and the mxml preloader displays but it loads a blank screen. When I path directly to the file it loads fully and works fine. Other possibly relevant information: The swf makes calls through GET requests to the database the site is built with codeigniter I'm using swfobject to load the swf you can see it in all it's busted glory here: http://thetoad.flattoads.com:16080/~iopdev/CI/index.php?c=moodtotem&m=index I'm going bonkers over this!

  • HTML button to NOT submit form

    - by arik-so
    Hello, I have a form. Outside that form, I have a button. A simple button, like this: <button>My Button</button> Nevertheless, when I click it, it submits the form. Here's the code: <form id="myform"> <input /> </form> <button>My Button</button> All this button should do is some JavaScript. But even when it looks just like in the code above, it submits the form. When I change the tag button to span, it works perfectly. But unfortunately, it needs to be a button. Is there any way to block that button from submitting the form? Like e. g. <button onclick="document.getElementById('myform').doNotSubmit();">My Button</button> 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?

  • Handling site not found and page not found with dynamic mass virtual hosting

    - by Rick Moynihan
    I have recently setup mass virtual hosting in Apache so that all we need to do is create a directory to create a new vhost. We're then also using wildcard DNS to map all subdomains to the server running our Apache instance. This works excellently, however I'm now having trouble configuring it to fail-over to an appropriate default/error-page when the vhost directory does not exist. The problem appears to be conflated between by my desire to handle the two error conditions: vhost not found i.e. there was no directory found matching the host supplied in the HTTP host header. I'd like this to display an appropriate site not found error page. The 404 page not found condition of the vhost. Additionally I have a specialised "api" vhost in its own vhost block. I've tried a number of variations and none seem to exhibit the behaviour I want. Here's what I'm working with right now: NameVirtualHost *:80 <VirtualHost *:80> DocumentRoot /var/www/site-not-found ServerName sitenotfound.mydomain.org ErrorDocument 500 /500.html ErrorDocument 404 /500.html </VirtualHost> <VirtualHost *:80> ServerName api.mydomain.org DocumentRoot /var/www/vhosts/api.mydomain.org/current # other directives, e.g. setting up passenger/rails etc... </VirtualHost> <VirtualHost *:80> # get the server name from the Host: header UseCanonicalName Off VirtualDocumentRoot /var/www/vhosts/%0/current # other directives ... e.g proxy passing to api etc... ErrorDocument 404 /404.html </VirtualHost> My understanding is that the first vhost block is used as the default, so I have this here as my catch all site. Next I have my API vhost, and then finally my mass vhost block. So for a domain that doesn't match the first two ServerName's and has no corresponding directory in /var/www/vhosts/ I'd expect it to fall-over to the first vhost, however with this setup, all domains resolve to my default site-not-found. Why is this? By putting the mass-vhost block first, I can get the mass-vhosts to resolve properly, but not my site-not-found vhost... and in this case I can't seem to find a way to distinguish between a page-level 404 in the vhost, and the case where the VirtualDocumentRoot fails to find a vhost directory (this appears to use the 404 also). Any help out of this bind is much appreciated!

  • Installation of Active Directory on separate VM from DNS does not entierly work - not sure why

    - by René Kåbis
    Not sure what I am doing wrong here. I have a moderately midrange server (16 cores, 2Ghz, 32GB ECC REG RAM, 6TB storage, nothing too extreme) where I am running Hyper-V (Server 2012 R2 Enterprise) in order to provision virtual machines. So why an AD separate from DNS? I want redundancy. I want to be able to move VMs and back them up individually and not have too many services on any one VM. I have already provisioned a VM with DNS, and have set it up right -- essentially, I have: Set up Static IP’s for everyone involved. Installed the DNS service on the DNS VM. Created a forward lookup zone and a reverse lookup zone (primary zone) xyz.ca Configured the zones to use nonsecure and secure dynamic updates (i will change this to secure later after the domain controller is online). Created a A record for the DC in the forward lookup zone (and a reverse ptr) Changed DC’s DNS server (network settings) to the new DNS server. Checked that I can ping the dns server from the new DC by hostname. When I went ahead and did a DCpromo on the DC, and un-cheked the “install DNS” option, everything seemed to go well (no error messages), but I saw no changes on the DNS server whatsoever (no additional settings). Plus, the DNS server seems to be unable to join the domain, as it claims that the domain is not discoverable. As a final note, I do run Symantec Endpoint Protection, which includes a firewall and most settings set as default. I have not yet tried turning this off, but my experience has been that if a service would open up a port on a Windows firewall, it would do the same through Symantec. There is pretty tight integration these days with corporate-class AV and Windows. I have a template vhdx fully set up (just short of any special roles and features) that I can use to replace the current AD VM with, so doing this all over again is not too much skin off of my nose.

  • Our winners- and some BBQ for everyone

    - by Steve Tunstall
    Congrats to our two winners for the first two comments on my last entry. Steve from Australia and John Lemon. Steve won since he was the first person over the International Date Line to see the post I made so late after a workday on Friday. So not only does he get to live in a country with the 2nd most beautiful women in the world, but now he gets some cool Oracle Swag, too. (Yes, I live on the beach in southern California, so you can guess where 1st place is for that other contest…Now if Steve happens to live in Manly, we may actually have a tie going…) OK, ok, for everyone else, you can be winners, too. How you ask? I will make you the envy of every guy and gal in your neighborhood or campsite. What follows is the way to smoke the best ribs you or anyone you know have ever tasted. Follow my instructions and give it a try. People at your party/cookout/campsite will tell you that they’re the best ribs they’ve ever had, and I will let you take all the credit. Yes, I fully realize this post is going to be longer than any post I’ve done yet. But let’s get serious here. Smoking meat is much more important, agreed? J In all honesty, this is a repeat of another blog I did, so I’m just copying and pasting. Step 1. Get some ribs. I actually really like Costco’s pack. They have both St. Louis and Baby Back. (They are the same ribs, but cut in half down the sides. St. Louis style is the ‘front’ of the ribs closest to the stomach, and ‘Baby back’ is the part of the ribs where is connects to the backbone). I like them both, so here you see I got one pack of each. About 4 racks to a pack. So these two packs for $25 each will feed about 16-20 of my guests. So around 3 bucks a person is a pretty good deal for the best ribs you’ll ever have. Step 2. Prep the ribs the night before you’re going to smoke. You need to trim them to fit your smoker racks, and also take off the membrane and add your rub. Then cover and set in fridge overnight. Here’s how to take off the membrane, which will not break down with heat and smoke like the rest of the meat, so must be removed. Use a butter knife to work in a ways between the membrane and the white bone. Just enough to make room for your finger. Try really hard not to poke through the membrane, you want to keep it whole. See how my gloved fingers can now start to lift up and pull off the membrane? This is what you are trying to do. It’s awesome when the whole thing can come off at once. This one is going great, maybe the best one I’ve ever done. Sometime, it falls apart and doesn't come off in one nice piece. I hate when that happens. Now, add your rub and pat it down once into the meat with your other hand. My rub is not secret. I got it from my mentor, a BBQ competitive chef who is currently ranked #1 in California and #3 in the nation on the BBQ circuit. He does full-day classes in southern California if anyone is interested in taking his class. Go to www.slapyodaddybbq.com to check him out. I tweaked his run recipe a tad and made my own. It’s one part Lawry’s, one part sugar, one part Montreal Steak Seasoning, one part garlic powder, one-half part red chili powder, one-half part paprika, and then 1/20th part cayenne. You can adjust that last ingredient, or leave it out. Real cheap stuff you can get at Costco. This lets you make enough rub to last about a year or two. Don’t make it all at once, make a shaker’s worth and use it up before you make more. Place it all in a bowl, mix well, and then add to a shaker like you see here. You can get a shaker with medium sized holes on it at any restaurant supply store or Smart & Final. The kind you see at pizza places for their red pepper flakes works best. Now cover and place in fridge overnight. Step 3. The next day. Ok, I’m ready to go. Get your stuff together. You will need your smoker, some good foil, a can of peach nectar, a bottle of Agave syrup, and a package of brown sugar. You will need this stuff later. I also use a clean spray bottle, and apple juice. Step 4. Make your fire, or turn on your electric smoker. In this example I’m using my portable charcoal smoker. I got this for only $40. I then modified it to be useful. Once modified, these guys actually work very well. Trust me, your food DOES NOT KNOW how expensive your smoker is. Someone who tells you that you need to spend a bunch of money on a smoker is an idiot. I also have an electric smoker that stays in my backyard. It’s cleaner and larger so I can smoke more food. But this little $40 one works great for going camping. Here is what my fire-bowl looks like. I leave a space in the middle open, and place cold charcoal and wood chucks in a circle going outwards. This makes it so when I dump the hot coals down the middle, they will slowly burn outwards, hitting different wood chucks at different times, allowing me to go 4-5 hours without having to even touch my fire. For ribs, I use apple and pecan wood. Pecan works for anything. Apple or any fruit wood is excellent for pork. So now I make my hot charcoal with a chimney only about half-full. I found a great use for that side-burner on my grill that I never use. It makes a fantastic chimney starter. You never use fluids of any kind, nor ever use that stupid charcoal that has lighter fluid built into it. Never, ever, ever. Step 5. Smoke. Add your ribs in the racks and stack them up in your smoker. I have a digital thermometer on a probe that I use to keep track of the temp in the smoker. I just lay the probe on the top rack and shut the lid. This cheap guy is a little harder to maintain the right temperature of around 225 F, so I do have to keep my eye on it more than my electric one or a more expensive charcoal one with the cool gadgets that regulate your temp for you. Every hour, spray apple juice all over your ribs using that spray bottle. After about 3 hours, you should have a very good crust (called the Bark) on your ribs. Once you have the Bark where you want it, carefully remove your ribs and place them in a tray. We are now ready for a very important part to make the flavor. Get a large piece of foil and place one rib section on it. Splash some of the peach nectar on it, and then a drizzle of the Agave syrup. Then, use your gloved hand to pack on some brown sugar. Do this on BOTH sides, and then completely wrap it up TIGHT in the foil. Do this for each rib section, and then place all the wrapped sections back into the smoker for another 4 to 6 hours. This is where the meat will get tender and flavorful. The first three hours is only to make the smoke bark. You don’t need smoke anymore, since the ribs are wrapped, you only need to keep the heat around 225 for the next 4-6 hours. Obviously you don’t spray anymore. Just time and slow heat. Be patient. It’s actually really hard to overdo it. You can let them go longer, and all that will happen is they will get even MORE tender!!! If you take them out too soon, they will be tough. How do you know? Take out one package (use long tongs) and open it up. If you grab a bone with your tongs and it just falls apart and breaks away from the rest of the meat, you are done!!! Enjoy!!! Step 6. Eat. It pulls apart like this when it’s done. By the way, smoking tri-tip is way easier. Just rub it with the same rub, and put in your smoker for about 2.5 hours at 250 F. That’s it. Low-maintenance. It comes out like this, with a fantastic smoke ring and amazing flavor. Thanks, and I will put up another good tip, about the ZFSSA, around the end of November. Steve

  • How do I use a jQuery not selector to select relative URLs?

    - by Matt
    I'm working on a little jQuery script to add Google Analytics pageTracker onclick data to all relative URLs on my forum, allowing me to track clicks to external sites. I don't want to add the onclick to internal links on forum.sitename or sitename, and I don't want to add them to any hrefs marked # or that start with /. My script below works nicely, but for one minor problem! All of the forum's URLs are relative and don't start with /. I appear to have no way to change that, so need to modify the jQuery below to prevent it adding the onclick to links like as it currently does. What I want to do, is to write a .not() function like .not("[href!^=http") to prevent jQuery from adding the onclick to any hrefs which do not start with http. However, .not() appears not to support this. I'm new to jQuery and can't figure this out. Any pointers would be massively appreciated. $(document).ready(function(){ // Get URL from a href var URL = $("a").attr('href'); // Add pageTracker data for GA tracking $("a") .not("[href^=#]") .not("[href^=http://forum.sitename]") .not("[href^=http://www.sitename]") .attr("onclick","pageTracker._trackEvent('Outgoing_Links', 'Forum', " + URL + ");") ; }); Thanks!

  • Serial number not found, copy of Windows not genuine

    - by sara
    I have an HP-G71-340US notebook that I purchased 11/29/09. When I power it up, a black screen comes on that shows "serial number not found" and it also says that my copy of Windows 7 Home Basic is not genuine – but my computer came with Windows 7 Home Premium. In BIOS, my serial number is not shown either and I did pull out the little battery to reset it which allowed me to bypass the suddenly new locked BIOS that needed a password to enter. I'm sure this is a masterpiece created by my 6 or 9 yr old child while trying to play on my laptop. Can I fix these two problems?

  • Why are 20% of keywords still provided when Google is using HTTPS across the board?

    - by Rajesh Magar
    Most of the searches that appear in my analytics are "not provided" because Google has encrypted their all searches. However, if all search results are now encrypted with HTTPS protocol then how is Google analytics still able to track some (20%) of the organic keywords details? There are still some keywords appearing in my organic keywords section. So how did Google analytics do this tracking? Does it bypass the HTTPS restrictions for the referrer?
