• SQL Cruise Alaska 2011

  - by Grant Fritchey

  I had the extreme good fortune to get sent on the last SQL Cruise to Alaska. I love my job. In case you don't what this is, SQL Cruise is a trip on a cruise ship during which you get to attend classes while on the boat, learning all about SQL Server and related topics as well as network with the instructors and the other Cruisers. Frankly, it's amazing. Classes ran from Monday, 5/30, to Saturday, 6/4. The networking was constant, between classes, at night on cruise ship, out on excursions in Alaskan rainforests and while snorkeling in ocean waters. Here's a run down of the experience from my point of view. Because I couldn't travel out 2 days early, I missed the BBQ that occurred the day before the cruise when many of the Cruisers received their swag bags. Some of that swag came from Red Gate. I researched what was useful on a cruise like this and purchased small flashlights and binoculars for all the Cruisers. The flashlights were because, depending on your cabin, ships can be very dark. The binoculars were so that the cruisers could watch all the beautiful landscape as it flowed by. I would have liked to have been there when the bags were opened, but I heard from several people that they appreciated the gifts. Cruisers "In" the hot tub. Pictured: Marjory Woody, Michele Grondin, Kyle Brandt, Grant Fritchey, John Halunen Sunday I went to board the ship with my wife. We had a bit of an adventure because I messed up our documents. It all worked out and we got on board to meet up at the back of the boat at one of the outdoor bars with the other Cruisers, thanks to tweets letting everyone know where to go. That was the end of electronic coordination on the trip (connectivity in Alaska was horrible for everyone except AT&T). The Cruisers were a great bunch of people and it was a real honor to meet them and get to spend time with them. After everyone settled into their cabins, our very first activity was a contest, sponsored by Red Gate. The Cruisers, in an effort to get to know each other and the ship, were required to go all over taking various photographs, some of them hilarious. The winning team of three would all win prizes. Some of the significant others helped out and I tagged along with a team that tied for first but lost the coin toss. The winning team consisted of Christina Leo (blog|twitter), Ryan Malcom (twitter), Neil Hambly (blog|twitter). They then had to do math and identify the cabin with the lowest prime number, oh, and get a picture of it and be the first to get back up to the bar where we were waiting. Christina came in first and very happily carried home an Ipad2. Ryan won a 1TB portable hard drive and Neil won a wireless mouse (picture below, note my special SQL Server Central Friday Shirt. Thanks Steve (blog|twitter)). Winners: Christina Leo, Neil Hambly, Ryan Malcolm. Just Lucky: Grant Fritchey Monday morning classes started. Buck Woody (blog|twitter) was a special guest speaker on this cruise. His theme was "Three C's on the High Seas: Career, Communication and Cloud." The first session was all on Career. I'm not going to type out all my notes from the session, but let's just say, if you get the chance to hear Buck talk about how to manage your career, I suggest you attend. I have a ton of blog posts that I'll be putting together over the next several months (yes, months) both here and over on ScaryDBA. I also have a bunch of work I'm going to be doing to get my career performance bumped up a notch or two (and let's face it, that won't be easy). Later on Monday, Tim Ford (blog|twitter) did a session on DMOs. Specifically the session was on Tim's Period Table of DMOs that he has put together, and how to use some of the more interesting DMOs in your day to day job. It was a great session, packed with good information. Next, Brent Ozar (blog|twitter) did a session on how to monitor and guide SAN configuration for the DBA that doesn't have access to the SAN. That was some seriously useful information. Tuesday morning we only had a single class. Kendra Little (blog|twitter) taught us all about "No Lock for Yes Fun".  It was all about the different transaction isolation levels and how they work. There is so often confusion in this area and Kendra does a great job in clarifying the information. Also, she tosses in her excellent drawings to liven up the presentation. Then it was excursion time in Juneau. My wife and I, along with several other Cruisers, took a hike up around the Mendenhall Glacier. It was absolutely beautiful weather and walking through the Alaskan rain forest was a treat. Our guide, Jason, was a great guy and it was a good day of hiking. Wednesday was an all day excursion in Skagway. My wife and I took the "Ghost and Good Time Girls" walking tour that ended up at a bar that used to be a brothel, the Red Onion. It was a great history of the town. We went back out and hit a few museums and exhibits. We also hiked up the side of the mountain to see the Dewey Lake and some great views of the town. Finally we hiked out to the far side of town to see the Gold Rush cemetery. Hiking done we went back to the boat and had a quiet dinner on our own. Thursday we cruised through Glacier Bay and saw at least four different glaciers including sitting next to the Marjory Glacier for  about an hour. It was amazing. Then it got better. We went into class with Buck again, this time to talk about Communication. Again, I've got pages of notes that I'm going to be referring back to for some time to come. This was an excellent opportunity to learn. Snorkelers: Nicole Bertrand, Aaron Bertrand, Grant Fritchey, Neil Hambly, Christina Leo, John Robel, Yanni Robel, Tim Ford Friday we pulled into Ketchikan. A bunch of us went snorkeling. Yes, snorkeling. Yes, in Alaska. Yes, snorkeling in the ocean in Alaska. It was fantastic. They had us put on 7mm thick wet suits (an adventure all by itself) so it was basically warm the entire time we were in the water (except for the occasional squirt of cold water down my back). Before we got in the water a bald eagle flew up and landed about 15 feet in front of us, which was just an incredible event. Then our guide pointed out about 14 other eagles in the area, hanging out in the trees. Wow! The water was pretty clear and there was a ton of things to see. That was absolutely a blast. Back on the boat I presented a session called Execution Plans: The Deep Dive (note the nautical theme). It seemed to go over well and I had several good questions come out of the session that will lead to new blog posts. After I presented, it was Aaron Bertrand's (blog|twitter) turn. He did a session on "What's New in Denali" that provided a lot of great information. He was able to incorporate new things straight out of Tech-Ed, so this was expanded beyond his usual presentation. The man really knows what he's talking about and communicates it well. Saturday we were travelling so there was time for a bunch of classes. Jeremiah Peschka (blog|twitter) did a great overview of some of the NoSQL databases and what they should be used for. The session was called "The Database is Dead" but it was really about how there are specific uses for these databases that SQL Server doesn't fill, but also that these databases can't replace SQL Server in other areas. Again, good material. Brent Ozar presented again with a session on Defensive Indexing. It was an overview of how indexes work and a deep dive into how to apply them appropriately in your databases to better support access. A good session, as you would expect. Then we pulled into Victoria, BC, in Canada and had a nice dinner with several of the Cruisers, including Denny Cherry (blog|twitter). After that it was back to Seattle on Sunday. By the way, the Science Fiction Museum in Seattle isn't a Science Fiction Museum any more. I was very disappointed to discover this. Overall, it was a great experience. I'm extremely appreciative of Red Gate for sending me and for Tim, Brent, Kendra and Jeremiah for having me. The other Cruisers were all amazing people and it was an honor & privilege to meet them and spend time with them. While this was a seriously fun time, it was also a very serious training opportunity with solid information coming from seasoned industry pros.

• Dell Poweredge 1950 with Perc 5i keeps losing raid config -> "Foreign Configuration Found"

  - by nosage

  The quick and dirty: the machine is a Dell Poweredge 1950, dual xeon quad cores, 8GB of ram, 2 2TB seagate SATAs in (supposed to be raid1) using a Perc 5i raid card. They are hot-swappable with a back-plane. I can build the raid fine and after a little while an install of server 08 r2 will blue screen and restart. When it comes up the raid controller says "Foreign Configuration Found." When I go into the raid configuration panel there is no raid listed but I can import the "foreign config", and the OS will boot up fine, until it blue screens again after a little while. The issue is OS independent. I have tried swapping raid cards, swapping the RAM module on the raid card and swapping the raid battery, all to no avail. Its almost as if there is a loose connection from the raid card to the back plane and both of disks get lost and the raid card drops the config. But it sees the disks fine when it boots back up. The raid card uses a SCSI SAS cable to connect to the back-plane so I guess the next step is to replace that, but... then I might as well replace the back-plane with a SCSI SAS to sata breakout cable, but... then I need a way to power the disks. Sorry for the wall of txt but it would be great to get some thoughts from people who worked with perc raid cards or poweredge servers with this type of issue before. Ironically I want to get this system up and running so I can work on MCITP labs. Thank you for any/all help and feel free to ask questions!

• Enum driving a Visual State change via the ViewModel

  - by Chris Skardon

  Exciting title eh? So, here’s the problem, I want to use my ViewModel to drive my Visual State, I’ve used the ‘DataStateBehavior’ before, but the trouble with it is that it only works for bool values, and the minute you jump to more than 2 Visual States, you’re kind of screwed. A quick search has shown up a couple of points of interest, first, the DataStateSwitchBehavior, which is part of the Expression Samples (on Codeplex), and also available via Pete Blois’ blog. The second interest is to use a DataTrigger with GoToStateAction (from the Silverlight forums). So, onwards… first let’s create a basic switch Visual State, so, a DataObj with one property: IsAce… public class DataObj : NotifyPropertyChanger { private bool _isAce; public bool IsAce { get { return _isAce; } set { _isAce = value; RaisePropertyChanged("IsAce"); } } } The ‘NotifyPropertyChanger’ is literally a base class with RaisePropertyChanged, implementing INotifyPropertyChanged. OK, so we then create a ViewModel: public class MainPageViewModel : NotifyPropertyChanger { private DataObj _dataObj; public MainPageViewModel() { DataObj = new DataObj {IsAce = true}; ChangeAcenessCommand = new RelayCommand(() => DataObj.IsAce = !DataObj.IsAce); } public ICommand ChangeAcenessCommand { get; private set; } public DataObj DataObj { get { return _dataObj; } set { _dataObj = value; RaisePropertyChanged("DataObj"); } } } Aaaand finally – hook it all up to the XAML, which is a very simple UI: A Rectangle, a TextBlock and a Button. The Button is hooked up to ChangeAcenessCommand, the TextBlock is bound to the ‘DataObj.IsAce’ property and the Rectangle has 2 visual states: IsAce and NotAce. To make the Rectangle change it’s visual state I’ve used a DataStateBehavior inside the Layout Root Grid: <i:Interaction.Behaviors> <ei:DataStateBehavior Binding="{Binding DataObj.IsAce}" Value="true" TrueState="IsAce" FalseState="NotAce"/> </i:Interaction.Behaviors> So now we have the button changing the ‘IsAce’ property and giving us the other visual state: Great! So – the next stage is to get that to work inside a DataTemplate… Which (thankfully) is easy money. All we do is add a ListBox to the View and an ObservableCollection to the ViewModel. Well – ok, a little bit more than that. Once we’ve got the ListBox with it’s ItemsSource property set, it’s time to add the DataTemplate itself. Again, this isn’t exactly taxing, and is purely going to be a Grid with a Textblock and a Rectangle (again, I’m nothing if not consistent). Though, to be a little jazzy I’ve swapped the rectangle to the other side (living the dream). So, all that’s left is to add some States to the template.. (Yes – you can do that), these can be the same names as the others, or indeed, something else, I have chosen to stick with the same names and take the extra confusion hit right on the nose. Once again, I add the DataStateBehavior to the root Grid element: <i:Interaction.Behaviors> <ei:DataStateBehavior Binding="{Binding IsAce}" Value="true" TrueState="IsAce" FalseState="NotAce"/> </i:Interaction.Behaviors> The key difference here is the ‘Binding’ attribute, where I’m now binding to the IsAce property directly, and boom! It’s all gravy!   So far, so good. We can use boolean values to change the visual states, and (crucially) it works in a DataTemplate, bingo! Now. Onwards to the Enum part of this (finally!). Obviously we can’t use the DataStateBehavior, it' only gives us true/false options. So, let’s give the GoToStateAction a go. Now, I warn you, things get a bit complex from here, instead of a bool with 2 values, I’m gonna max it out and bring in an Enum with 3 (count ‘em) 3 values: Red, Amber and Green (those of you with exceptionally sharp minds will be reminded of traffic lights). We’re gonna have a rectangle which also has 3 visual states – cunningly called ‘Red’, ‘Amber’ and ‘Green’. A new class called DataObj2: public class DataObj2 : NotifyPropertyChanger { private Status _statusValue; public DataObj2(Status status) { StatusValue = status; } public Status StatusValue { get { return _statusValue; } set { _statusValue = value; RaisePropertyChanged("StatusValue"); } } } Where ‘Status’ is my enum. Good times are here! Ok, so let’s get to the beefy stuff. So, we’ll start off in the same manner as the last time, we will have a single DataObj2 instance available to the Page and bind to that. Let’s add some Triggers (these are in the LayoutRoot again). <i:Interaction.Triggers> <ei:DataTrigger Binding="{Binding DataObject2.StatusValue}" Value="Amber"> <ei:GoToStateAction StateName="Amber" UseTransitions="False" /> </ei:DataTrigger> <ei:DataTrigger Binding="{Binding DataObject2.StatusValue}" Value="Green"> <ei:GoToStateAction StateName="Green" UseTransitions="False" /> </ei:DataTrigger> <ei:DataTrigger Binding="{Binding DataObject2.StatusValue}" Value="Red"> <ei:GoToStateAction StateName="Red" UseTransitions="False" /> </ei:DataTrigger> </i:Interaction.Triggers> So what we’re saying here is that when the DataObject2.StatusValue is equal to ‘Red’ then we’ll go to the ‘Red’ state. Same deal for Green and Amber (but you knew that already). Hook it all up and start teh project. Hmm. Just grey. Not what I wanted. Ok, let’s add a ‘ChangeStatusCommand’, hook that up to a button and give it a whirl: Right, so the DataTrigger isn’t picking up the data on load. On the plus side, changing the status is making the visual states change. So. We’ll cross the ‘Grey’ hurdle in a bit, what about doing the same in the DataTemplate? <Codey Codey/> Grey again, but if we press the button: (I should mention, pressing the button sets the StatusValue property on the DataObj2 being represented to the next colour). Right. Let’s look at this ‘Grey’ issue. First ‘fix’ (and I use the term ‘fix’ in a very loose way): The Dispatcher Fix This involves using the Dispatcher on the View to call something like ‘RefreshProperties’ on the ViewModel, which will in turn raise all the appropriate ‘PropertyChanged’ events on the data objects being represented. So, here goes, into turdcode-ville – population – me: First, add the ‘RefreshProperties’ method to the DataObj2: internal void RefreshProperties() { RaisePropertyChanged("StatusValue"); } (shudder) Now, add it to the hosting ViewModel: public void RefreshProperties() { DataObject2.RefreshProperties(); if (DataObjects != null && DataObjects.Count > 0) { foreach (DataObj2 dataObject in DataObjects) dataObject.RefreshProperties(); } } (double shudder) and now for the cream on the cake, adding the following line to the code behind of the View: Dispatcher.BeginInvoke(() => ((MoreVisualStatesViewModel)DataContext).RefreshProperties()); So, what does this *ahem* code give us: Awesome, it makes the single bound data object show the colour, but frankly ignores the DataTemplate items. This (by the way) is the same output you get from: Dispatcher.BeginInvoke(() => ((MoreVisualStatesViewModel)DataContext).ChangeStatusCommand.Execute(null)); So… Where does that leave me? What about adding a button to the Page to refresh the properties – maybe it’s a timer thing? Yes, that works. Right, what about using the Loaded event then eh? Loaded += (s, e) => ((MoreVisualStatesViewModel) DataContext).RefreshProperties(); Ahhh No. What about converting the DataTemplate into a UserControl? Anything is worth a shot.. Though – I still suspect I’m going to have to ‘RefreshProperties’ if I want the rectangles to update. Still. No. This DataTemplate DataTrigger binding is becoming a bit of a pain… I can’t add a ‘refresh’ button to the actual code base, it’s not exactly user friendly. I’m going to end this one now, and put some investigating into the use of the DataStateSwitchBehavior (all the ones I’ve found, well, all 2 of them are working in SL3, but not 4…)

• Voxel Engine in Multiplayer?

  - by Oliver Schöning

  This is a question more out of Interest for now, because I am not even near to the point that I could create this project at the moment. I really like the progress on the Atomontage Engine. A Voxel engine that is WIP at the moment. I would like to create a Voxel SERVER eventually. First in JavaScript (That's what I am learning right now) later perhaps in C++ for speed. Remember, I am perfectly aware that this is very hard! This is a brainstorm for the next 10 years as for now. What I would like to achieve one day is a Multiplayer Game in the Browser where the voxels positions are updated by XYZ input from the server. The Browser Does only 3 things: sending player input to the server, updating Voxel positions send from the server and rendering the world. I imagine using something like the Three.js libary on the client side. So that would be my programming dream right there... Now to something simpler for the near future. Right now I am learning javascript. And I am making games with Construct2. (A really cool JavaScript "game maker") The plan is to create a 2D Voxel enviorment (Block Voxels) on the Socket.IO Server* and send the position of the Voxels and Players to the Client side which then positions the Voxel Blocks to the Server Output coordinates. I think that is a bit more manageable then the other bigger idea. And also there should be no worries about speed with this type of project in JavaScript (I hope). Extra Info: *I am using nodejs (Without really knowing what it does besides making Socket.IO work) So now some questions: Is the "dream project" doable in JavaScript? Or is C++ just the best option because it does not take as long to be interpreted at run time like JavaScript? What are the limitations? I can think of some: Need of a Powerful server depending on how much information the server has to process. Internet Speed; Sending the data of the Voxel positions to every player could add up being very high! The browser FPS might go down quickly if rendering to many objects. One way of fixing reducing the packages Could be to let the browser calculate some of the Voxel positions from Several Values. But that would slow down the Client side too. What about the more achievable project? I am almost 100% convinced that this is possible in JavaScript, and that there are several ways of doing this. This is just XY position Updating for now.. Hope this did make some sense. Please comment if you got something to say :D

• Did you forget me?

  - by Ratman21

  I know it has been a long time since I last blogged. Still at it, looking for work in the “IT” field. Had another phone interview (only found out during the interview that it was for one year contract job, but I still would take it) for a Help Desk job. Didn’t get it, they thought I was not a application support person and more of a hardware support. Gee..I started out in “IT” as a programmer. Then a programmer/computer operator, then a Tandem/Lan operator and finally a Network operator. I had to deal with so many different operating systems, software and applications.   And they thought I was too hardware. Well I am working a temp day job with the U.S. Census. It gets me out of the house and out in the country. If find getting paid to check for living quarters not bad job, except for the many houses I find that are up for sale and looks like it was not the owners (former owners it seems) idea, with the kids toys still in the yards. Not good for some one with a over active imagine or for my truck. So far I have backed in to ditch (and had to be pulled out), in to power pole (no damage to pole and very little to truck) and a mail box (no damage to truck but mail box was leaning a little) in the last two weeks.   Oh an I have started reading/using “The Love Dare” book from the movie “Fireproof”. I restarted (yes I have had to go back to day one from day five) the dare this Sunday. Dare one dare/day one “Love Is Patient” and the first dare is (reading from the book is): “The first part of this dare is fairly simple. Although Love is communicated in a number of ways. Our words often reflect the condition of our heart. For the next day, resolve to demonstrate patience and to sys nothing negative to your spouse at all. If the temptation arises, choose not to say anything. It’s better to hold your tongue that to say something you’ll regret. “. This was almost too easy as I can hold back from saying anything bad to any one but, this can also be a problem in life (you hold back for so long and!!!!!!!!!!!!!! Boom). Check back for dare/day two “Love Is Kind”.

• Game Over function is not working Starling

  - by aNgeLyN omar

• How exactly are textures drawn on faces of cubes?

  - by Christian Frantz

  Are they drawn from the lower left corner clockwise? I know how triangles are created, I'm not just sure if textures are the same way. The texture on my cube is skewed way off and after playing around with the U,V coordinates, I still can't get it right. //front left bottom corner ok vertices[0] = (new VertexPositionTexture(new Vector3(0, 0, 0), new Vector2(1, 0))); //front left upper corner vertices[1] = (new VertexPositionTexture(new Vector3(0, 1, 0), new Vector2(1, 1))); //front right upper corner ok vertices[2] = (new VertexPositionTexture(new Vector3(1, 1, 0), new Vector2(0, 1))); //front lower right corner vertices[3] = (new VertexPositionTexture(new Vector3(1, 0, 0), new Vector2(0, 0))); //back left lower corner ok vertices[4] = (new VertexPositionTexture(new Vector3(0, 0, -1), new Vector2(0, 1))); //back left upper corner vertices[5] = (new VertexPositionTexture(new Vector3(0, 1, -1), new Vector2(1, 1))); //back right upper corner ok vertices[6] = (new VertexPositionTexture(new Vector3(1, 1, -1), new Vector2(1, 0))); //back right lower corner vertices[7] = (new VertexPositionTexture(new Vector3(1, 0, -1), new Vector2(0, 0)));

• Windows product key is valid but wont activate

  - by pnongrata

  Last month, I needed to install Windows XP (Pro Version 2002 SP3) from a Reinstallation CD a co-worker gave me, and with a product key the IT team told me to use. Everything installed successfully and I have been using the XP machine for the last 30 days without any problems; however it kept reminding me to activate Windows, and of course, I never did (laziness). It now has me locked out of my machine and won't let me log in until I activate it. So I proceed to the Activation Screen which asks me: Do you want to activate Windows now? I choose "Yes, let's activate Windows over the Internet now.", and click the Next button. It now asks me: Do you want to register while you are activating Windows? I choose "No, I don't want to register now; let's just activate Windows.", and click the Next button. I now see the following screen: Notice how the title reads "Unauthorized product key", and how there are only 3 buttons: Telephone Remind me later Retry Please note that the Retry button is disabled until I enter the full product key that IT gave me, then it enables. However, at no point in time do I see a Next button, indicating that the product key was valid/successful. So instead, I just click the Retry button, and the screen refreshes, this time with a different title Incorrect product key Could something be wrong with the Windows XP reinstallation CD (do they "expire" after a certain amount of time, etc.)? Or is this the normal/typical workflow for what happens when you just have a bad product key? I ask because, after this happened I emailed IT and they supplied me whether several other product keys to try. But every time its the same result, same thing happening over again and again. So I guess it's possible that IT has given me several bad keys, but it's more likely something else is going on here. Any thoughts or ways to troubleshoot? Thanks in advance!

• Visual Studio 2010 plus Help Index : have your cake and eat it too

  - by Adrian Hara

  Although the team's intentions might have been good, the new help system in Visual Studio 2010  is a huge step backwards (more like a cannonball-shot-kind-of-leap really) from the one we all know (and love?) in Visual Studio 2008 and 2005 (and heck, even VS6). Its biggest problem, from my point of view, is the total and complete lack of the Help Index feature: you know...the thing where you just go and type in what you're looking for and it filters down the list of results automatically. For me this was the number one productivity feature in the "old" help system, allowing me to find stuff very quickly. Number two is that it's entirely web based and runs, by default, in the browser. So imagine, when you press F1, a new tab opens in your default browser pointing to the help entry. While this is wrong in many ways, it's also extremely annoying, cleaning up tabs in the browser becomes a chore which represents a serious productivity hit. These and many other problems were discussed extensively (and rather vocally) on connect but it seems MS seemed to ignore it and opt to release the new help system anyway, with the promise that more features will be added in a later release. Again, it kind of amazes me that they chose to ship a product with LESS features that the previous one and, what's worse, missing KEY features, just so it's "standards based" and "extensible". To be honest, I couldn't care less about the help system's implementation, I just want it to be usable and I would've thought that by now the software community and especially MS would've learned this lesson. In the end, what kind of saddens me is that MS regards these basic features as ones for the "power help user". I mean, come on! I mean a) it's not like my aunt's using Visual Studio 2010 and she represents the regular user, b) all software developers are, by definition, power users and c) it's a freakin help, not rocket science! As you can tell, I'm pretty pissed. Even more so because I really feel that the VS2010 & co. release really is a great one, with a lot of effort going into the various platforms and frameworks, most (if not all) of them being really REALLY good products. And then they go and screw up the help! How lame is that?!   Anyway, it's not all gloom-and-doom. Luckily there is a desktop app which presents a UI over the new help system that's very close to what was there in VS2008, by Robert Chandler (to which I hereby declare eternal gratitude). It still has some minor issues but I'll take it over the browser version of the help any day. It's free, pretty quick (on my machine ;)) and nicely usable. So, if you hate the new help system (passionately) like I do, download H3Viewer now.

• Page_BlockSubmit - reset it to False, if there is a scenario when page doesn't postback on validation error

  - by Vipin

  Recently, I was facing a problem where if there was a validation error, and if I changed the state of checkbox it won't postback on first attempt. But when I uncheck and check again , it postbacks on second attempt...this is some quirky behaviour in .ASP.Net platform. The solution was to reset Page_BlockSubmit flag to false and it works fine. The following explanation is from http://lionsden.co.il/codeden/?p=137&cpage=1#comment-143   Submit button on the page is a member of vgMain, so automatically it will only run the validation on that group. A solution is needed that will run validation on multiple groups and block the postback if needed. Solution Include the following function on the page: function DoValidation() { //validate the primary group var validated = Page_ClientValidate('vgPrimary ');   //if it is valid if (validated) { //valid the main group validated = Page_ClientValidate('vgMain'); }   //remove the flag to block the submit if it was raised Page_BlockSubmit = false;   //return the results return validated; } Call the above function from the submit button’s OnClientClick event. <asp:Button runat="server" ID="btnSubmit" CausesValidation="true" ValidationGroup="vgMain" Text="Next" OnClick="btnSubmit_Click" OnClientClick="return DoValidation();" /> What is Page_BlockSubmit When the user clicks on a button causing a full post back, after running Page_ClientValidate ASP.NET runs another built in function ValidatorCommonOnSubmit. Within Page_ClientValidate, Page_BlockSubmit is set based on the validation. The postback is then blocked in ValidatorCommonOnSubmit if Page_BlockSubmit is true. No matter what, at the end of the function Page_BlockSubmit is always reset back to false. If a page does a partial postback without running any validation and Page_BlockSubmit has not been reset to false, the partial postback will be blocked. In essence the above function, RunValidation, acts similar to ValidatorCommonOnSubmit. It runs the validation and then returns false to block the postback if needed. Since the built in postback is never run, we need to reset Page_BlockSubmit manually before returning the validation result.

• Static site generator with web-based file manager?

  - by user234

  I'm checking around options of static web site generators which led me to lots of articles about them! However, no word is spoken on how to edit files through a browser; it's always assumed you have either DropBox or some FTPish or terminal access. The only generator I could find that includes a browser based admin screen is Kirby (getkirby.com, mentioned at modernstatic.com) Besides the application above, what setup would you recommend to have both static HTML generation and web-based file management? Thanks!

• Trouble upgrading OS X, because HD doesn't use GUID Partition Table Scheme

  - by Erik Vold

  So I have a MacBook with Mac OS X 10.5 and I'm trying to upgrade to 10.6, but when I run the upgrade 'install' I quickly get to a page where I am supposed to 'Select the disk where you want to install Mac OS X' and there is only the one hard drive, so it is auto selected, and below that I see a warning message and the only button available is the 'Go Back' button. The warning message says: "Macintosh HD" can't be used because it doesn't use the GUID Partition Table scheme. Use Disk Utility to change the partition scheme. Select the disk, choose the Partition tab, select the Volume Scheme and then click Options. So I followed the above instructions, and I got to the last step, where I'm supposed to click the 'Options' button, the problem is that I cannot click that button, it is disabled.. So what am I supposed to do?

  I have recently started using Ubuntu 13.04. The other day I found the Firefox browser blocked by malware. The website was from Europol and said that it had blocked the browser and that 'everything' had been encrypted. have uninstalled Firefox. I can still access files but I was wondering how I can eradicate this malware from my laptop. I have tried to install ClamAV, it did not work but the 2 do not have to be related.

• Tracking traffic and/or referrals from iPad applications

  - by kayaker243

  In Google Analytics, there is extensive information on the mobile device, version and browser version. However, this doesn't seem to go beyond the mobile browser. I would like to determine which application is responsible for visits to my site. Specifically, I want to know how many visits are coming from zite. http://www.handsetdetection.com/properties/vendormodel/Apple/iPad/page:4 seems to indicate this information is probably available, where/does Google Analytics expose this?

• Program to customize mouse buttons?

  - by roflwaffle

  I have a Logitech M510 wireless mouse and am on a Mac. Right now I can assign different actions to the 2 thumb buttons through the Logitech control panel. What I want to do is have mouse button combos to perform actions. So if I am holding thumb button 1 and click the left button, a tab will close in Chrome. As well as any other "hold one button, click another" combination. Is there any program out there that gives this type of customization?

• Not able to setup Tomboy Web for Ubuntu One

  - by Karthik

  I have been trying to setup Tomboy Web in Ubuntu 12.04 but without much success. I press the "Connect to Server" in the Preferences dialog and the expected result is for your browser to open, with the Authorization page. But, in my case, Firefox opens but the authorization page does not open at all. Some details: My default browser is Chrome, but Firefox always opens that to with a non-default profile. Note: I have already browsed through most of the other articles in AskUbuntu regarding TomBoy Synchronization, but none of them discuss this particular problem

• Recommended total system backup solution

  - by bioShark

  I hope this question won't get closed immediately since it has a generic title. I already searched a bit around the answers here, but nothing satisfied me. I want a back-up solution that makes a total back-up, so that I can restore my Ubuntu in case of major failures, like HDD failing. As far as I can see, I have 2 choices: 1) Backing up with Deja Dup to an external disk. This is fine and I am already doing, but in case my HDD fails, and I make a new Ubuntu install on a new disk, will Deja Dup be able to restore all my setting and stuff from the backed up files? If it can, then what other files/folders should I add in Deja Dup to back-up (currently I have set only the recommended /home folder)? Is there a point in telling Deja Dup to back-up everything under "/" ? 2) A disk/partition cloning software. This would be something similar to Noton ghost. Is there such a software with nice GUI that you could recommend for Ubuntu? And even better, it would be nice if Ubuntu's liveCD could recognize such a clone at install step. I am using 11.10
