• SQL SERVER – Sends backups to a Network Folder, FTP Server, Dropbox, Google Drive or Amazon S3

  - by pinaldave

  Let me tell you about one of the most useful SQL tools that every DBA should use – it is SQLBackupAndFTP. I have been using this tool since 2009 – and it is the first program I install on a SQL server. Download a free version, 1 minute configuration and your daily backups are safe in the cloud. In summary, SQLBackupAndFTP Creates SQL Server database and file backups on schedule Compresses and encrypts the backups Sends backups to a network folder, FTP Server, Dropbox, Google Drive or Amazon S3 Sends email notifications of job’s success or failure SQLBackupAndFTP comes in Free and Paid versions (starting from $29) – see version comparison. Free version is fully functional for unlimited ad hoc backups or for scheduled backups of up to two databases – it will be sufficient for many small customers. What has impressed me from the beginning – is that I understood how it works and was able to configure the job from a single form (see Image 1 – Main form above) Connect to you SQL server and select databases to be backed up Click “Add backup destination” to configure where backups should go to (network, FTP Server, Dropbox, Google Drive or Amazon S3) Enter your email to receive email confirmations Set the time to start daily full backups (or go to Settings if you need Differential or  Transaction Log backups on a flexible schedule) Press “Run Now” button to test You can get to this form if you click “Settings” buttons in the “Schedule section”. Select what types of backups and how often you want to run them and you will see the scheduled backups in the “Estimated backup plan” list A detailed tutorial is available on the developer’s website. Along with SQLBackupAndFTP setup gives you the option to install “One-Click SQL Restore” (you can install it stand-alone too) – a basic tool for restoring just Full backups. However basic, you can drag-and-drop on it the zip file created by SQLBackupAndFTP, it unzips the BAK file if necessary, connects to the SQL server on the start, selects the right database, it is smart enough to restart the server to drop open connections if necessary – very handy for developers who need to restore databases often. You may ask why is this tool is better than maintenance tasks available in SQL Server? While maintenance tasks are easy to set up, SQLBackupAndFTP is still way easier and integrates solution for compression, encryption, FTP, cloud storage and email which make it superior to maintenance tasks in every aspect. On a flip side SQLBackupAndFTP is not the fanciest tool to manage backups or check their health. It only works reliably on local SQL Server instances. In other words it has to be installed on the SQL server itself. For remote servers it uses scripting which is less reliable. This limitations is actually inherent in SQL server itself as BACKUP DATABASE command  creates backup not on the client, but on the server itself. This tool is compatible with almost all the known SQL Server versions. It works with SQL Server 2008 (all versions) and many of the previous versions. It is especially useful for SQL Server Express 2005 and SQL Server Express 2008, as they lack built in tools for backup. I strongly recommend this tool to all the DBAs. They must absolutely try it as it is free and does exactly what it promises. You can download your free copy of the tool from here. Please share your experience about using this tool. I am eager to receive your feedback regarding this article.

• Adventures in MVVM &ndash; ViewModel Location and Creation

  - by Brian Genisio's House Of Bilz

  More Adventures in MVVM In this post, I am going to explore how I prefer to attach ViewModels to my Views.  I have published the code to my ViewModelSupport project on CodePlex in case you'd like to see how it works along with some examples.  Some History My approach to View-First ViewModel creation has evolved over time.  I have constructed ViewModels in code-behind.  I have instantiated ViewModels in the resources sectoin of the view. I have used Prism to resolve ViewModels via Dependency Injection. I have created attached properties that use Dependency Injection containers underneath.  Of all these approaches, I continue to find issues either in composability, blendability or maintainability.  Laurent Bugnion came up with a pretty good approach in MVVM Light Toolkit with his ViewModelLocator, but as John Papa points out, it has maintenance issues.  John paired up with Glen Block to make the ViewModelLocator more generic by using MEF to compose ViewModels.  It is a great approach, but I don’t like baking in specific resolution technologies into the ViewModelSupport project. I bring these people up, not to name drop, but to give them credit for the place I finally landed in my journey to resolve ViewModels.  I have come up with my own version of the ViewModelLocator that is both generic and container agnostic.  The solution is blendable, configurable and simple to use.  Use any resolution mechanism you want: MEF, Unity, Ninject, Activator.Create, Lookup Tables, new, whatever. How to use the locator 1. Create a class to contain your resolution configuration: public class YourViewModelResolver: IViewModelResolver { private YourFavoriteContainer container = new YourFavoriteContainer(); public YourViewModelResolver() { // Configure your container } public object Resolve(string viewModelName) { return container.Resolve(viewModelName); } } Examples of doing this are on CodePlex for MEF, Unity and Activator.CreateInstance. 2. Create your ViewModelLocator with your custom resolver in App.xaml: <VMS:ViewModelLocator x:Key="ViewModelLocator"> <VMS:ViewModelLocator.Resolver> <local:YourViewModelResolver /> </VMS:ViewModelLocator.Resolver> </VMS:ViewModelLocator> 3. Hook up your data context whenever you want a ViewModel (WPF): <Border DataContext="{Binding YourViewModelName, Source={StaticResource ViewModelLocator}}"> This example uses dynamic properties on the ViewModelLocator and passes the name to your resolver to figure out how to compose it. 4. What about Silverlight? Good question.  You can't bind to dynamic properties in Silverlight 4 (crossing my fingers for Silverlight 5), but you CAN use string indexing: <Border DataContext="{Binding [YourViewModelName], Source={StaticResource ViewModelLocator}}"> But, as John Papa points out in his article, there is a silly bug in Silverlight 4 (as of this writing) that will call into the indexer 6 times when it binds.  While this is little more than a nuisance when getting most properties, it can be much more of an issue when you are resolving ViewModels six times.  If this gets in your way, the solution (as pointed out by John), is to use an IndexConverter (instantiated in App.xaml and also included in the project): <Border DataContext="{Binding Source={StaticResource ViewModelLocator}, Converter={StaticResource IndexConverter}, ConverterParameter=YourViewModelName}"> It is a bit uglier than the WPF version (this method will also work in WPF if you prefer), but it is still not all that bad.  Conclusion This approach works really well (I suppose I am a bit biased).  It allows for composability from any mechanisim you choose.  It is blendable (consider serving up different objects in Design Mode if you wish... or different constructors… whatever makes sense to you).  It works in Cider.  It is configurable.  It is flexible.  It is the best way I have found to manage View-First ViewModel hookups.  Thanks to the guys mentioned in this article for getting me to something I love using.  Enjoy.

• RTL (Arabic and Hebrew) Support for Windows Phone 7

  - by Daniel Moth

  Problem and Background Currently there is no support for Right-To-Left rendering in Windows Phone 7, when developing with Silverlight (itself built on .NET Compact Framework). When I encountered that limitation, I had a flashback to 2005 when I complained about the luck of RTL on NETCF. Unfortunately, the partial solution I proposed back then requires PInvoke and there is no such support on Windows Phone today. Fortunately, my RTL requirements this time were more modest: all I wanted to do was display correctly a translation (of Hebrew or Arabic) in my FREE WP7 translator app. For v1.0 of the app, the code received a string from the service and just put it up on the screen as the translated text. In Arabic and Hebrew, that string (incorrectly) appeared reversed. I knew that, but decided that since it is a platform limitation, I could live with it and so could the users. Yuval P, a colleague at Microsoft, pushed me to offer support for Hebrew (something that I wasn't motivated to pursue if I am honest). After many back and forths, we landed on some code that works. It is certainly not the most efficient code (quite the opposite), but it works and met the bar of minimum effort for v1.1. Thanks Yuval for insisting and contributing most of the code! After Hebrew support was there, I thought the same solution would work for Arabic. Apparently, reversing the Arabic text is not enough: Arabic characters render themselves differently dependent on what preceded/succeeds them(!). So I needed some kind of utility that takes a reversed Arabic string and returns the same string but with the relevant characters "fixed". Luckily, another MS colleague has put out such a library (thanks Bashar): http://arabic4wp7.codeplex.com/. RTL Solution So you have a reversed RTL string and want to make it "right" before displaying on the screen. This is what worked for me (ymmv). Need to split the string into "lines". Not doing this and just reversing the string and sticking it a wrapping text control means that the user not only has to read right to left, they also have to read bottom up. The previous step must take into account a line length that works for both portrait and landscape modes, and of course, not break words in the middle, i.e. find natural breaks. For each line, break it up into words and reverse the order of the words and the order of the letters within each word On the previous step, do not reverse words that should be preserved, e.g. Windows and other such English words that are mixed in with the Arabic or Hebrew words. The same exclusion from reversal applies to numbers. Specifically, for Arabic, once there is a word that is reversed also change its characters. For some code paths, the above has to take into account whether the translation is "from" an RTL language or if it is "to" an RTL language. I packaged the solution in a single code file containing a static class (see the 'Background" section above for… background and credits). Download RTL.cs for your Windows Phone app (to see its usage in action download for FREE "The best translator app") Enjoy, and if you decide to improve on the code, feel free to share back with me… Comments about this post welcome at the original blog.

• SQL SERVER – Discard Results After Query Execution – SSMS

  - by pinaldave

  The first thing I do any day is to turn on the computer. Today I woke up and as soon as I turned on the computer I saw a chat message from a friend. He was a bit confused and wanted me to help him. Just as usual I am keeping the relevant conversation in focus and documenting our conversation as chat. Let us call him Ajit. Ajit: Pinal, every time I run a query there is no result displayed in the SSMS but when I run the query in my application it works and returns an appropriate result. Pinal:  Have you tried with different parameters? Ajit: Same thing. However, it works from another computer when I connect to the same server with the same query parameters? Pinal: What? That is new and I believe it is something to do with SSMS and not with the server. Send me screenshot please. Ajit: I believe so, let me send you a screenshot, Pinal: (looking at the screenshot) Oh man, there is no result-tab at all. Ajit: That is what the problem is. It does not have the tab which displays the result. This works just fine from another computer. Pinal: Have you referred Nakul’s blog post – SSMS – Query result options – Discard result after query executes, that talks about setting which can discard the query results after execution. (After a while) Ajit: I think it seems like on the computer where I am running the query my SSMS seems to have the option enabled related to discarding results. I fixed it by following Nakul’s blog post. Pinal: Great! Quite often I get the question what is the importance of the feature. Let us first see how to turn on or turn off this feature in SQL Server Management Studio 2012. In SSMS 2012 go to Tools >> Options >> Query Results > SQL Server >> Results to Grid >> Discard Results After Query Execution. When enabled this option will discard results after the execution. The advantage of disabling the option is that it will improve the performance by using less memory. However the real question is why would someone enable or disable the option. What are the cases when someone wants to run the query but do not care about the result? Matter of the fact, it does not make sense at all to run query and not care about the result. The matter of the fact, I can see quite a few reasons for using this option. I often enable this option when I am doing performance tuning exercise. During performance tuning exercise when I am working with execution plans and do not need results to verify every time or when I am tuning Indexes and its effect on execution plan I do not need the results. In this kind of situations I do keep this option on and discard the results. It always helps me big time as in most of the performance tuning exercise I am dealing with huge amount of the data and dealing with this data can be expensive. Nakul’s has done the experiment here already but I am going to repeat the same again using AdventureWorks Database. Run following T-SQL Script with and without enabling the option to discard the results. USE AdventureWorks2012 GO SELECT * FROM Sales.SalesOrderDetail GO 10 After enabling Discard Results After Query Execution After disabling Discard Results After Query Execution Well, this is indeed a good option when someone is debugging the execution plan or does not want the result to be displayed. Please note that this option does not reduce IO or CPU usage for SQL Server. It just discards the results after execution and a good help for debugging on the development server.

• Experience the iPad UI On Your PC

  - by Matthew Guay

  Want to test drive iPad without heading over to an Apple store?  Here’s a way you can experience some of the iPad UI straight from your browser! The iPad is the latest gadget from Apple to wow the tech world, and people even waited in line all night to be one of the first to get their hands on one.  Thanks to a simple JavaScript trick, however, you can get a feel for some of its new features without leaving your computer.  This won’t let you try out everything on the iPad, but it will let you see how the new lists and pop-over menus work just like they do in the new apps. Test drive the iPad’s UI from your browser Normally, the Apple iPhone developer library online looks like a standard webpage. But, on the iPad, it looks and feels like a full-blown native iPad app.  With a nifty JavaScript trick from boredzo.org you can use this same interface on your PC.  Since the iPad uses the Safari browser, we ran this test in Safari for Windows.  If you don’t already have it installed, you can download it from Apple (link below) and setup as normal. Now, open Safari and browse to Apple’s developer page at: http://www.developer.apple.com   Now, enter the following in the address bar, and press Enter. javascript:localStorage.setItem('debugSawtooth', 'true')   Finally, click this link to go to the iPhone OS documentation. http://developer.apple.com/iphone/library/iPad/ After a short delay, it should open in full iPad style! The left menu works just like the menus on the iPad, complete with transitions.  It feels entirely like a native application, instead of a webpage.  To scroll through text, click and pull up or down similar to the way you would use it on a touch screen. Some pages even include a pop-over menu like many of the new iPad apps use. Note that the page will be rendered for the size of your browser, and if you resize your window the page will not resize with it.  Simply press F5 to reload the page, and it will resize to fit the new window size.  If you resize your window to be tall and narrow, like the iPad in horizontal mode, the webpage will change and the left menu will disappear in lieu of a drop-down menu just like it would if you rotated the iPad. This works in Chrome as well, since it, like Safari, is based on Webkit.  However, it didn’t seem to work in our test on Firefox or other browsers. We’ve previously covered how you can experience some of the iPhone’s UI with the online iPhone user guide.  Check it out if you haven’t yet: View Mobile Websites in Windows with Safari 4 Developer Tools Conclusion Although this doesn’t let you really try out all of the iPad’s interface, it at least gives you a taste of how it works.  It’s exciting to see how much functionality can be packed into webapps today.  And don’t forget, How-to Geek is giving away an iPad to a random fan!  Head over to our Facebook page and fan How-to Geek if you haven’t already done so.

• ArchBeat Top 10 for December 2-8, 2012

  - by Bob Rhubart

  The Top 10 most-clicked items shared on the OTN ArchBeat Facebook page for the week of December 2-8, 2012 Configure Oracle SOA JMSAdatper to Work with WLS JMS Topics Another of the four posts published on Dec 4 by the Fusion Middleware A-Team blogger identified as "fip" illlustrates "how to configure the JMS Topic, the JmsAdapter connection factory, as well as the composite so that the JMS Topic messages will be evenly distributed to same composite running off different SOA cluster nodes without causing duplication." Web Service Example - Part 3: Asynchronous Part 3 in this series from the Oracle ADF Mobile blog looks at "firing the web service asynchronously and then filling in the UI when it completes." Denis says, "This can be useful when you have data on the device in a local store and want to show that to the user while the application uses lazy loading from a web service to load more data." Advanced Oracle SOA Suite Oracle Open World 2012 SOA Presentations Oracle SOA & BPM Partner Community blogger Juergen Kress shares a list of 13 SOA presentations delivered or moderated by Oracle SOA Product Management at OOW12 in San Francisco. Oracle WebLogic Server WLS Domain Browser My colleague Jeff Davies, a frequent speaker at OTN Architect Day events and a genuinely nice guy, emailed me last night with this message: "I just came across this app on Google Play. It allows WebLogic administrators to browse WLS 12c domain information. I installed it on my phone and tried it out. Works very fast." I'm an iPhone guy, but I'm perfectly comfortable taking Jeff at his word. The app is called WLS Domain Browser. Follow the link for more info from the Google Play site. Retrieve Performance Data from SOA Infrastructure Database Another of the four blog posts published on Dec 4 by very busy Oracle Fusion Middleware A-Team member "fip," this one offers "examples of some basic SQL queries you can run against the infrastructure database of Oracle SOA Suite 11G to acquire the performance statistics for a given period of time." How to Achieve OC4J RMI Load Balancing "Having returned from a customer who faced challenges with OC4J RMI load balancing, I felt there is still some confusion in the field [about] how OC4J RMI load balancing works," says the Oracle Fusion Middleware A-Team member known only as "fip." "Hence I decide to dust off an old tech note that I wrote a few years back and share it with the general public." From XaaS to Java EE – Which damn cloud is right for me in 2012? Oracle ACE Director Markus Eisele wrestles with a timely technical issue and shares his observations on several of the alternatives. Exalogic 2.0.1 Tea Break Snippets - Creating a ModifyJeOS VirtualBox "One of the main advantages of this is that Templates can be created away from the Exalogic Environment," explains The Old Toxophilist. (BTW: I had to look it up: a toxophilist is one who collects bows and arrows.) ADF Mobile - Implementing Reusable Mobile Architecture "Reusability was always a strong part of ADF," says Oracle ACE Director Andrejus Baranovskis. "The same high reusability level is supported now in ADF Mobile." The objective of this post is "to prove technically that [the] reusable architecture concept works for ADF Mobile." Using BPEL Performance Statistics to Diagnose Performance Bottlenecks Someone had a busy day… This post, one of four published on DeC 4 by a member of the Oracle Fusion Middleware A-Team identified only as "fip," offers details on how to "enable, retrieve and interpret the performance statistics, before the future versions provides a more pleasant user experience." Thought for the Day "If you're afraid to change something it is clearly poorly designed." — Martin Fowler Source: SoftwareQuotes.com

• Drawing transparent glyphs on the HTML canvas

  - by Bertrand Le Roy

  The HTML canvas has a set of methods, createImageData and putImageData, that look like they will enable you to draw transparent shapes pixel by pixel. The data structures that you manipulate with these methods are pseudo-arrays of pixels, with four bytes per pixel. One byte for red, one for green, one for blue and one for alpha. This alpha byte makes one believe that you are going to be able to manage transparency, but that’s a lie. Here is a little script that attempts to overlay a simple generated pattern on top of a uniform background: var wrong = document.getElementById("wrong").getContext("2d"); wrong.fillStyle = "#ffd42a"; wrong.fillRect(0, 0, 64, 64); var overlay = wrong.createImageData(32, 32), data = overlay.data; fill(data); wrong.putImageData(overlay, 16, 16); .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } where the fill method is setting the pixels in the lower-left half of the overlay to opaque red, and the rest to transparent black. And here’s how it renders: As you can see, the transparency byte was completely ignored. Or was it? in fact, what happens is more subtle. What happens is that the pixels from the image data, including their alpha byte, replaced the existing pixels of the canvas. So the alpha byte is not lost, it’s just that it wasn’t used by putImageData to combine the new pixels with the existing ones. This is in fact a clue to how to write a putImageData that works: we can first dump that image data into an intermediary canvas, and then compose that temporary canvas onto our main canvas. The method that we can use for this composition is drawImage, which works not only with image objects, but also with canvas objects. var right = document.getElementById("right").getContext("2d"); right.fillStyle = "#ffd42a"; right.fillRect(0, 0, 64, 64); var overlay = wrong.createImageData(32, 32), data = overlay.data; fill(data); var overlayCanvas = document.createElement("canvas"); overlayCanvas.width = overlayCanvas.height = 32; overlayCanvas.getContext("2d").putImageData(overlay, 0, 0); right.drawImage(overlayCanvas, 16, 16); And there is is, a version of putImageData that works like it should always have:

• Prefilling an SMS on Mobile Devices with the sms: Uri Scheme

  - by Rick Strahl

  Popping up the native SMS app from a mobile HTML Web page is a nice feature that allows you to pre-fill info into a text for sending by a user of your mobile site. The syntax is a bit tricky due to some device inconsistencies (and quite a bit of wrong/incomplete info on the Web), but it's definitely something that's fairly easy to do.In one of my Mobile HTML Web apps I need to share a current location via SMS. While browsing around a page I want to select a geo location, then share it by texting it to somebody. Basically I want to pre-fill an SMS message with some text, but no name or number, which instead will be filled in by the user.What worksThe syntax that seems to work fairly consistently except for iOS is this:sms:phonenumber?body=messageFor iOS instead of the ? use a ';' (because Apple is always right, standards be damned, right?):sms:phonenumber;body=messageand that works to pop up a new SMS message on the mobile device. I've only marginally tested this with a few devices: an iPhone running iOS 6, an iPad running iOS 7, Windows Phone 8 and a Nexus S in the Android Emulator. All four devices managed to pop up the SMS with the data prefilled.You can use this in a link:<a href="sms:1-111-1111;body=I made it!">Send location via SMS</a>or you can set it on the window.location in JavaScript:window.location ="sms:1-111-1111;body=" + encodeURIComponent("I made it!");to make the window pop up directly from code. Notice that the content should be URL encoded - HTML links automatically encode, but when you assign the URL directly in code the text value should be encoded.Body onlyI suspect in most applications you won't know who to text, so you only want to fill the text body, not the number. That works as you'd expect by just leaving out the number - here's what the URLs look like in that case:sms:?body=messageFor iOS same thing except with the ;sms:;body=messageHere's an example of the code I use to set up the SMS:var ua = navigator.userAgent.toLowerCase(); var url; if (ua.indexOf("iphone") > -1 || ua.indexOf("ipad") > -1) url = "sms:;body=" + encodeURIComponent("I'm at " + mapUrl + " @ " + pos.Address); else url = "sms:?body=" + encodeURIComponent("I'm at " + mapUrl + " @ " + pos.Address); location.href = url;and that also works for all the devices mentioned above.It's pretty cool that URL schemes exist to access device functionality and the SMS one will come in pretty handy for a number of things. Now if only all of the URI schemes were a bit more consistent (damn you Apple!) across devices...© Rick Strahl, West Wind Technologies, 2005-2013Posted in IOS  JavaScript  HTML5   Tweet !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs"); (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

• Ubuntu keyboard shortcuts - two-part question

  - by Don

  Background: I come from a Windows background and just started dual-booting Ubuntu (my first Linux experience) about 4 days ago. So my systems are Windows 7/Ubuntu 12.04, and so far I'm loving Ubuntu. I am a dedicated mouse-abolitionist (trackpads are hell) and do most of my browsing and navigation with keyboard shortcuts. However, on switching to Ubuntu, a lot of my keyboard shortcuts are gone, and my productivity has resultantly taken a huge hit anytime I am using Ubuntu. Problem 1: My computer was designed to display on-screen notifications for a second when I hit caps-lock or num-lock, and there are no constant indicators of the lock status (LEDs, etc). In Ubuntu, the keys still worked, but the notifications were gone. Googling got me a tutorial on key-binding(Compiz) and scripts, so now I have capslock and numlock running this script: #!/bin/bash icon="/usr/share/icons/gnome/scalable/devices/keyboard.svg" case $1 in 'scrl') mask=3 key="Scroll" ;; 'num') mask=2 key="Num" ;; 'caps') mask=1 key="Caps" ;; esac value=$(xset q | grep "LED mask" | sed -r "s/.*LED mask:\s+[0-9a-fA-F]+([0-9a-fA-F]).*/\1/") if [ $(( 0x$value & 0x$mask )) == $mask ] then output="$key Lock" output2="On" else output="$key Lock" output2="Off" fi notify-send -i $icon "$output" "$output2" -t 1000 But, whether turning it off or on, the notifications always say that I have turned it on. Is there an easy fix for this, or an easier way to work it to get it do display the CORRECT notifications? Problem 2: I'm not sure if this is because of my keyboard or Ubuntu. In Windows, I use Chrome and use the ctrl+pgUp/pgDwn shortcuts quite a bit to switch between tabs. On my keyboard, I can enter pgUp and pgDwn by either disabling NumLock and hitting 9 or 3 respectively on the 10key. Alternately I can hold the fn key and hit up or down arrow. The first method is the one I very heavily relied upon, and it works in Firefox for Ubuntu, but not in Chrome nor in Chromium. The second method (ctrl + fn + up/down) works fine in Chrome. However, I'd dearly like to find a method to make the first method work. Any suggestions? Thanks in advance for your help. Update: @julien: I've checked the keyboard layout options - I didn't find anything that seemed useful for this goal. @Marty: The script runs once when the button is pressed. In Compiz, I've tied those two keys to the script, so when I press the button, it runs the script with the button pressed as a parameter. Update: @elmicha: Thanks. That one works a lot better, and it even pops an icon into the status bar when caps lock is on. There's still a very slight problem in that if I quickly tap the key twice, the image will show that it has been turned on and then turned off, and the notifaction will come and go from my status area, but the text of both notifications will be "Caps Lock on". Same with Num Lock. However, if the time between presses is long enough for the first notification to disappear, everything displays correctly. Given how quickly the notifications disappear, I don't expect this will pose too much of a problem for me.

• Drawing texture does not work anymore with a small amount of triangles

  - by Paul

  When i draw lines, the vertices are well connected. But when i draw the texture inside the triangles, it only works with i<4 in the for loop, otherwise with i<5 for example, there is a EXC_BAD_ACCESS message, at @synthesize textureImage = _textureImage. I don't understand why. (The generatePolygons method seems to work fine as i tried to draw lines with many vertices as in the second image below. And textureImage remains the same for i<4 or i<5 : it's a 512px square image). Here are the images : What i want to achieve is to put the red points and connect them to the y-axis (the green points) and color the area (the green triangles) : If i only draw lines, it works fine : Then with a texture color, it works for i<4 in the loop (the red points in my first image, plus the fifth one to connect the last y) : But then, if i set i<5, the debug tool says EXC_BAD_ACCESS at the synthesize of _textureImage. Here is my code : I set a texture color in HelloWordLayer.mm with : CCSprite *textureImage = [self spriteWithColor:color3 textureSize:512]; _terrain.textureImage = textureImage; Then in the class Terrain, i create the vertices and put the texture in the draw method : @implementation Terrain @synthesize textureImage = _textureImage; //EXC_BAD_ACCESS for i<5 - (void)generatePath2{ CGSize winSize = [CCDirector sharedDirector].winSize; float x = 40; float y = 0; for(int i = 0; i < kMaxKeyPoints+1; ++i) { _hillKeyPoints[i] = CGPointMake(x, y); x = 150 + (random() % (int) 30); y += 30; } } -(void)generatePolygons{ _nPolyVertices = 0; float x1 = 0; float y1 = 0; int keyPoints = 0; for (int i=0; i<4; i++){ /* HERE : 4 = OK / 5 = crash */ //V0: at (0,0) _polyVertices[_nPolyVertices] = CGPointMake(x1, y1); _polyTexCoords[_nPolyVertices++] = CGPointMake(x1, y1); //V1: to the first "point" _polyVertices[_nPolyVertices] = CGPointMake(_hillKeyPoints[keyPoints].x, _hillKeyPoints[keyPoints].y); _polyTexCoords[_nPolyVertices++] = CGPointMake(_hillKeyPoints[keyPoints].x, _hillKeyPoints[keyPoints].y); keyPoints++; //from point at index 0 to 1 //V2, same y as point n°2: _polyVertices[_nPolyVertices] = CGPointMake(0, _hillKeyPoints[keyPoints].y); _polyTexCoords[_nPolyVertices++] = CGPointMake(0, _hillKeyPoints[keyPoints].y); //V1 again _polyVertices[_nPolyVertices] = _polyVertices[_nPolyVertices-2]; _polyTexCoords[_nPolyVertices++] = _polyVertices[_nPolyVertices-2]; //V2 again _polyVertices[_nPolyVertices] = _polyVertices[_nPolyVertices-2]; _polyTexCoords[_nPolyVertices++] = _polyVertices[_nPolyVertices-2]; //V3 = same x,y as point at index 1 _polyVertices[_nPolyVertices] = CGPointMake(_hillKeyPoints[keyPoints].x, _hillKeyPoints[keyPoints].y); _polyTexCoords[_nPolyVertices] = CGPointMake(_hillKeyPoints[keyPoints].x, _hillKeyPoints[keyPoints].y); y1 = _polyVertices[_nPolyVertices].y; _nPolyVertices++; } } - (id)init { if ((self = [super init])) { [self generatePath2]; [self generatePolygons]; } return self; } - (void) draw { //glDisable(GL_TEXTURE_2D); glDisableClientState(GL_COLOR_ARRAY); glDisableClientState(GL_TEXTURE_COORD_ARRAY); glBindTexture(GL_TEXTURE_2D, _textureImage.texture.name); glColor4f(1, 1, 1, 1); glVertexPointer(2, GL_FLOAT, 0, _polyVertices); glTexCoordPointer(2, GL_FLOAT, 0, _polyTexCoords); glDrawArrays(GL_TRIANGLE_STRIP, 0, (GLsizei)_nPolyVertices); glColor4f(1, 1, 1, 1); for(int i = 1; i < 40; ++i) { ccDrawLine(_polyVertices[i-1], _polyVertices[i]); } // restore default GL states glEnable(GL_TEXTURE_2D); glEnableClientState(GL_COLOR_ARRAY); glEnableClientState(GL_TEXTURE_COORD_ARRAY); } Do you see anything wrong in this code? Thanks for your help

• Does Jquery and Mootools usually have conflict if both are used on a webpage? [migrated]

  - by Charming Prince

  I have this website am designing, i tried using mootools 1.31 to animate some of the div boxes when clicked or when the mouse hover rounds it, to shows the content. the thing is that it doesn't seem to work on the webpage, but if i try the same script on a blank webpage it works, am thinking probably it's because i have Jquery 1.52 on the same page and maybe both scripts are conflicting with each other because, if i remove the Jquery, the Mootools works. What should be my option, because i need the Jquery to do some validations for me, so i can't remove it completely. Here are the codes <script> //-vertical var mySlide = new Fx.Slide('test'); $('slidein').addEvent('click', function(e){ e = new Event(e); mySlide.slideIn(); e.stop(); }); $('slideout').addEvent('click', function(e){ e = new Event(e); mySlide.slideOut(); e.stop(); }); $('toggle').addEvent('click', function(e){ e = new Event(e); mySlide.toggle(); e.stop(); }); $('hide').addEvent('click', function(e){ e = new Event(e); mySlide.hide(); e.stop(); }); </script> here's the HTML <html> <h3 class="section">Fx.Slide Vertical</h3> <a id="slideout" href="#">slideout</a> | <a id="slidein" href="#">slidein</a> | <a id="toggle" href="#"> toggle</a> | <a id="hide" href="#">hide</a> <div id="test"> Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

• Fun tips with Analytics

  - by user12620172

  If you read this blog, I am assuming you are at least familiar with the Analytic functions in the ZFSSA. They are basically amazing, very powerful and deep. However, you may not be aware of some great, hidden functions inside the Analytic screen. Once you open a metric, the toolbar looks like this: Now, I’m not going over every tool, as we have done that before, and you can hover your mouse over them and they will tell you what they do. But…. Check this out. Open a metric (CPU Percent Utilization works fine), and click on the “Hour” button, which is the 2nd clock icon. That’s easy, you are now looking at the last hour of data. Now, hold down your ‘Shift’ key, and click it again. Now you are looking at 2 hours of data. Hold down Shift and click it again, and you are looking at 3 hours of data. Are you catching on yet? You can do this with not only the ‘Hour’ button, but also with the ‘Minute’, ‘Day’, ‘Week’, and the ‘Month’ buttons. Very cool. It also works with the ‘Show Minimum’ and ‘Show Maximum’ buttons, allowing you to go to the next iteration of either of those. One last button you can Shift-click is the handy ‘Drill’ button. This button usually drills down on one specific aspect of your metric. If you Shift-click it, it will display a “Rainbow Highlight” of the current metric. This works best if this metric has many ‘Range Average’ items in the left-hand window. Give it a shot. Also, one will sometimes click on a certain second of data in the graph, like this:  In this case, I clicked 4:57 and 21 seconds, and the 'Range Average' on the left went away, and was replaced by the time stamp. It seems at this point to some people that you are now stuck, and can not get back to an average for the whole chart. However, you can actually click on the actual time stamp of "4:57:21" right above the chart. Even though your mouse does not change into the typical browser finger that most links look like, you can click it, and it will change your range back to the full metric. Another trick you may like is to save a certain view or look of a group of graphs. Most of you know you can save a worksheet, but did you know you could Sync them, Pause them, and then Save it? This will save the paused state, allowing you to view it forever the way you see it now.  Heatmaps. Heatmaps are cool, and look like this:  Some metrics use them and some don't. If you have one, and wish to zoom it vertically, try this. Open a heatmap metric like my example above (I believe every metric that deals with latency will show as a heatmap). Select one or two of the ranges on the left. Click the "Change Outlier Elimination" button. Click it again and check out what it does.  Enjoy. Perhaps my next blog entry will be the best Analytic metrics to keep your eyes on, and how you can use the Alerts feature to watch them for you. Steve

• Does *every* project benefit from written specifications?

  - by nikie

  I know this is holy war territory, so please read the question to the end before answering. There are many cases where written specifications make a lot of sense. For example, if you're a contractor and you want to get paid, you need written specs. If you're working in a team with 20 persons, you need written specs. If you're writing a programming language compiler or interpreter (and it's not perl), you'll usually write a formal specification. I don't doubt that there are many more cases where written specifications are a really good idea. I just think that there are cases where there's so little benefit in written specs, that it doesn't outweigh the costs of writing and maintaining them. EDIT: The close votes say that "it is difficult to say what is asked here", so let me clarify: The usefulness of written, detailed specifications is often claimed like a dogma. (If you want examples, look at the comments.) But I don't see the use of them for the kind of development I'm doing. So what is asked here is: How would written specifications help me? Background information: I work for a small company that's developing vertical market software. If our product is easier to use and has better performance than the competition, it sells. If it's harder to use, even if it behaves 100% as the specification says, it doesn't sell. So there are no "external forces" for having written specs. The advantage would have to be somewhere in the development process. Now, I can see how frozen specifications would make a developer's life easier. But we'll never have frozen specs. If we see in the middle of development that feature X is not intuitive to use the way it's specified, then we can only choose between changing the specification or developing a product that won't sell. You'll probably ask by now: How do you know when you're done? Well, we're continually improving our product. The competition does the same. So (hopefully) we're never done. We keep improving the software, and when we reach a point when the benefits of the improvements we've added since the last release outweigh the costs of an update, we create a new release that is then tested, localized, documented and deployed. This also means that there's rarely any schedule pressure. Nobody has to do overtime to make a deadline. If the feature isn't done by the time we want to release the next version, it'll simply go into the next version. The next question might be: How do your developers know what they're supposed to implement? The answer is: They have a lot of domain knowledge. They know the customers business well enough, so a high-level description of the feature (or even just the problem that the customer needs solved) is enough to implement it. If it's not clear, the developer creates a few fake screens to get feedback from marketing/management or customers, but this is nowhere near the level of detail of actual specifications. This might be inefficient for larger teams, but for a small team with low turnover it works quite well. It has the additional benefit that the developer in question often comes up with a better solution than the person writing the specs might have. This question is already getting very long, but let me address one last point: Testing. Like I said in the beginning, if our software behaves 100% like the spec says, it still can be crap. In fact, if it's so unintuitive that you need a spec to know how to test it, it probably is crap. It makes sense to have fixed, written tests for some core functionality and for regression bugs, but again, this is nowhere near a full written spec of how the software should behave when. The main test is: hand the software to a user who doesn't know it yet and tell him to use the new feature X. If she can figure out how to use it and it works, it works.

• OpenGL Fast-Object Instancing Error

  - by HJ Media Studios

  I have some code that loops through a set of objects and renders instances of those objects. The list of objects that needs to be rendered is stored as a std::map, where an object of class MeshResource contains the vertices and indices with the actual data, and an object of classMeshRenderer defines the point in space the mesh is to be rendered at. My rendering code is as follows: glDisable(GL_BLEND); glEnable(GL_CULL_FACE); glDepthMask(GL_TRUE); glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); glEnable(GL_DEPTH_TEST); for (std::map<MeshResource*, std::vector<MeshRenderer*> >::iterator it = renderables.begin(); it != renderables.end(); it++) { it->first->setupBeforeRendering(); cout << "<"; for (unsigned long i =0; i < it->second.size(); i++) { //Pass in an identity matrix to the vertex shader- used here only for debugging purposes; the real code correctly inputs any matrix. uniformizeModelMatrix(Matrix4::IDENTITY); /** * StartHere fix rendering problem. * Ruled out: * Vertex buffers correctly. * Index buffers correctly. * Matrices correct? */ it->first->render(); } it->first->cleanupAfterRendering(); } geometryPassShader->disable(); glDepthMask(GL_FALSE); glDisable(GL_CULL_FACE); glDisable(GL_DEPTH_TEST); The function in MeshResource that handles setting up the uniforms is as follows: void MeshResource::setupBeforeRendering() { glEnableVertexAttribArray(0); glEnableVertexAttribArray(1); glEnableVertexAttribArray(2); glEnableVertexAttribArray(3); glEnableVertexAttribArray(4); glBindBuffer(GL_ELEMENT_ARRAY_BUFFER, iboID); glBindBuffer(GL_ARRAY_BUFFER, vboID); glVertexAttribPointer(0, 3, GL_FLOAT, GL_FALSE, sizeof(Vertex), 0); // Vertex position glVertexAttribPointer(1, 3, GL_FLOAT, GL_FALSE, sizeof(Vertex), (const GLvoid*) 12); // Vertex normal glVertexAttribPointer(2, 2, GL_FLOAT, GL_FALSE, sizeof(Vertex), (const GLvoid*) 24); // UV layer 0 glVertexAttribPointer(3, 3, GL_FLOAT, GL_FALSE, sizeof(Vertex), (const GLvoid*) 32); // Vertex color glVertexAttribPointer(4, 1, GL_UNSIGNED_SHORT, GL_FALSE, sizeof(Vertex), (const GLvoid*) 44); //Material index } The code that renders the object is this: void MeshResource::render() { glDrawElements(GL_TRIANGLES, geometry->numIndices, GL_UNSIGNED_SHORT, 0); } And the code that cleans up is this: void MeshResource::cleanupAfterRendering() { glDisableVertexAttribArray(0); glDisableVertexAttribArray(1); glDisableVertexAttribArray(2); glDisableVertexAttribArray(3); glDisableVertexAttribArray(4); } The end result of this is that I get a black screen, although the end of my rendering pipeline after the rendering code (essentially just drawing axes and lines on the screen) works properly, so I'm fairly sure it's not an issue with the passing of uniforms. If, however, I change the code slightly so that the rendering code calls the setup immediately before rendering, like so: void MeshResource::render() { setupBeforeRendering(); glDrawElements(GL_TRIANGLES, geometry->numIndices, GL_UNSIGNED_SHORT, 0); } The program works as desired. I don't want to have to do this, though, as my aim is to set up vertex, material, etc. data once per object type and then render each instance updating only the transformation information. The uniformizeModelMatrix works as follows: void RenderManager::uniformizeModelMatrix(Matrix4 matrix) { glBindBuffer(GL_UNIFORM_BUFFER, globalMatrixUBOID); glBufferSubData(GL_UNIFORM_BUFFER, 0, sizeof(Matrix4), matrix.ptr()); glBindBuffer(GL_UNIFORM_BUFFER, 0); }

• WPF MVVM ComboBox SelectedItem or SelectedValue not working

  - by cjibo

  Update After a bit of investigating. What seems to be the issue is that the SelectedValue/SelectedItem is occurring before the Item source is finished loading. If I sit in a break point and weight a few seconds it works as expected. Don't know how I'm going to get around this one. End Update I have an application using in WPF using MVVM with a ComboBox. Below is the ViewModel Example. The issue I'm having is when we leave our page and migrate back the ComboBox is not selecting the current Value that is selected. View Model public class MyViewModel { private MyObject _selectedObject; private Collection<Object2> _objects; private IModel _model; public MyViewModel(IModel model) { _model = model; _objects = _model.GetObjects(); } public Collection<MyObject> Objects { get { return _objects; } private set { _objects = value; } } public MyObject SelectedObject { get { return _selectedObject; } set { _selectedObject = value; } } } For the sake of this example lets say MyObject has two properties (Text and Id). My XAML for the ComboBox looks like this. XAML <ComboBox Name="MyComboBox" Height="23" Width="auto" SelectedItem="{Binding Path=SelectedObject,Mode=TwoWay}" ItemsSource="{Binding Objects}" DisplayMemberPath="Text" SelectedValuePath="Id"> No matter which way I configure this when I come back to the page and the object is reassembled the ComboBox will not select the value. The object is returning the correct object via the get in the property though. I'm not sure if this is just an issue with the way the ComboBox and MVVM pattern works. The text box binding we are doing works correctly.

• "SignTool error: Access is denied" in TFS 2010 build process

  - by user351352

  I'm getting "SignTool Error: Access is Denied" when I attempt to sign a file. When I use an administrator cmd, all works fine. However, this process is going to be used in a TFS 2010 build process and using the InvokeProcess task with signtool gives the same access denied message as a non-administrator command prompt. More info: On a Win2008 R2 enterprise machine. User is machine admin and on the domain. The TFS Build service is also set to run as this user. Using a self signed certificate created using these instructions: How do I create a self-signed certificate for code signing on Windows? After following these instructions I have the following files: MyCA.cer MyCA.pvk MySPC.cer MySPC.pvk MySPC.pfx MyCA is in my Trusted Root Certification Authorities I imported MySPC.pfx into personal certificates, following the advice here: SignTool error: Access is denied To do the signing I'm using the thumbprint of the MySPC.pfx that was imported into the Personal section so my signtool command looks like: sign /sha1 1e9d7b5ad98552d9c58944e3f3903e6b929f4819 /t http://timestamp.verisign.com/scripts/timestamp.dll "FileName" Once again this works in Admin mode. This also works when running cmd as administrator: sign /f "C:\Code Signing Non-Release\MySPC.pfx" /t http://timestamp.verisign.com/scripts/timestamp.dll "FileName" New to code signing in general, so any help is welcome.

• new ActiveXObject('Word.Application') creates new winword.exe process when IE security does not allo

  - by Mark Ott

  We are using MS Word as a spell checker for a few fields on a private company web site, and when IE security settings are correct it works well. (Zone for the site set to Trusted, and trusted zone modified to allow control to run without prompting.) The script we are using creates a word object and closes it afterward. While the object exists, a winword.exe process runs, but it is destroyed when the word object is closed. If our site is not set in the trusted zone (Internet zone with default security level) the call that creates the word object fails as expected, but the winword.exe process is still created. I do not have any way to interact with this process in the script, so the process stays around until the user logs off (users have no way to manually destroy the process, and it wouldn't be a good solution even if they did.) The call that attempts to create the object is... try { oWordApplication = new ActiveXObject('Word.Application'); } catch(error) { // irrelevant code removed, described in comments.. // notify user spell check cannot be used // disable spell check option } So every time the page is loaded this code may be run again, creating yet another orphan winword.exe process. oWordApplication is, of course, undefined in the catch block. I would like to be able to detect the browser security settings beforehand, but I have done some searching on this and do not think that it is possible. Management here is happy with it as it is. As long as IE security is set correctly it works, and it works well for our purposes. (We may eventually look at other options for spell check functionality, but this was quick, inexpensive, and does everything we need it to do.) This last problem bugs me and I'd like to do something about it, but I'm out of ideas and I have other things that are more in need of my attention. Before I put it aside, I thought I'd ask for suggestions here...

• Telerik ASP.NET AJAX - Ajax Update Label with dynamic created Docks

  Hi, i try to Update a simple Label on Close Event of dynamic created RadDock. Works fine so far, Label gets the correct values but doesnt updates it. RadDock dock = new RadDock(); dock.DockMode = DockMode.Docked; dock.UniqueName = Guid.NewGuid().ToString(); dock.ID = string.Format("RadDock{0}", dock.UniqueName); dock.Title = slide.slideName; dock.Text = string.Format("Added at {0}", DateTime.Now); dock.Width = Unit.Pixel(300); dock.AutoPostBack = true; dock.CommandsAutoPostBack = true; dock.Command += new DockCommandEventHandler(dock_Command); ... void dock_Command(object sender, DockCommandEventArgs e) { Status.Text = "Removed " + ((RadDock)sender).Title + " " + ((RadDock)sender).Text; } I tried to do this: RadAjaxManager1.AjaxSettings.AddAjaxSetting(dock, Status, null); while creating the docks, but on runtime i get a NullReference Excepetion. On a Button registered with the RadAjaxManager it works to show the value assigned by dock_command. protected void Button1_Click(object sender, EventArgs e) { Status.Text = Status.Text; } UPDATE: The RadAjaxManager was created with integrated Wizzard of VS2008. Can't select the Docks, because the are generated while runtime. On Backend its included in AutoCompletion, so the NullReference has nothing to do with the AjaxManager itself.

• InnerHTML IE 8 doesn't work properly? Resetting form.

  - by Craig Whitley

  Yeah this works in FF and Chrome, but for some reason wont work in IE 8. I'm using a radio button to clear a section of a form.. that section is a select box, but I don't want to leave the area empty - instead I want to reset it to what it was when the page loaded. At the moment IE8 is just leaving me with an empty small select box. Html: <select id="city_select" disabled="true" name="location_id" onchange="show_search_button();"><option selected>Select your city</option> </select> Javascript: document.getElementById('city_select').innerHTML = "<option selected>Select your city</option>"; I've also tried using location_id instead of city_select in the javascript but to no avail.. innerText and innerContent dont work either.. though the inner.HTML works in IE8 for an earlier function, but that isnt trying to innerHTML into a form. Does anybody know why this works in Chrome and FF but not IE8? and is there a solution to this? Any help appreciated thanks!

• Eclipse Helios - Not Stopping at Breakpoints (Help!)

  - by Rylie

  Dear Eclipse Expert, I recently upgraded from Eclipse Galileo to Helios. Helios stops at breakpoints ONLY when debugging "as a PHP Script", but not when debugging "as a Web Page". When debugging as a web page, it looks like the correct debug query string to start a debug session is getting tacked on to the url, like so: http://localhost/hello.php?XDEBUG_SESSION_START=ECLIPSE_DBGP &KEY=129798139020511 but elipse does not stop at the breakpoints. It just zooms thru the code and displays the output in the browser. This is my xdebug configuration in php.ini that works for Galileo, but is not working for Helios: (click here to see my entire xdebug config settings) ;extension=xdebug.so <-- is this needed? zend_extension=" /Applications/MAMP/bin/php5.3/lib/php/extensions/no-debug-no n-zts-20090626/xdebug.so " xdebug.remote_enable=on xdebug.remote_autostart=off xdebug.remote_handler=dbgp xdebug.remote_mode=req xdebug.remote_host=127.0.0.1 xdebug.remote_port=9000 xdebug.idekey= ; to enable remote debugging zend_debugger.allow_hosts=127.0.0.1/32 zend_debugger.expose_remotely=always Can you post your xdebug configuration that works for Helios? If possible, can you share the xdebug portion of your phpinfo() output? Would like to compare settings of an xdebug configuration that works on Helios with what I have. Thanks in advance. Rylie

• JSF invoke backing bean method and reRender components on ENTER key

  - by Markos Fragkakis

  Hi, I have a datatable with as search fields. I want a method on the backing bean to be invoked when ENTER key is pressed, as well as the DataTable to be re-rendered. My approach so far only works in IE 6, and 7, not in FF. This is the inputText: <h:inputText value="#{applicantProductListBean.applicantNameFilterValue}" id="applicantNameFilterValue" onkeypress="submitByEnter(event)"> </h:inputText> and this is the Javascript method I am invoking: function submitByEnter(e){ if(e.keyCode==13){ // alert("Enter was pressed"); e.returnValue=false; e.cancel=true; document.getElementById("applicantProductListForm:refreshButton").click(); } } As you can see, the Javascript method clicks on the button refresh, which exists on the page: <a4j:commandButton value="Refresh" id="refreshButton" action="#{applicantProductListBean.refreshData}" image="/images/icons/refresh48x48.gif" reRender="table, scroller"> </a4j:commandButton> The refreshData method does not return anything. As said before, this only works in IE 6 and IE 7. Does anyone know why it does not work in FF? An alternative I was considering was HotKey, which can indeed catch the event of ENTER, but it can only invoke Javascript, so it isn't appropriate. Is the proper way to do this via RichFaces or plain JSF? Cheers! UPDATE: Slightly modified the answer by BalusC, the script that works is: if (event.preventDefault) { // Firefox event.preventDefault(); } else { // IE event.returnValue = false; }

Note that I also have SQL Server 2008 installed, so the other day I did a Windows Update and decided to include SQL Server 2008 SP1 in my update. After doing that, my SSAS 2005 cube is no longer accessible from my application. I'm able to browse the data just fine within SQL Server 2005 BI Studio Manager, but I'm not able to connect to the cube from my application. Here is my connection string that used to work: Data Source=localhost;Provider=msolap;Initial Catalog=Adventure Works DW Here is the error message I get: Either the user, [Server]/[User], does not have access to the Adventure Works DW database, or the database does not exist. Here is the beginning of my stack trace if it would help: Microsoft.AnalysisServices.AdomdClient.AdomdErrorResponseException was unhandled by user code HelpLink="" Message="Either the user, Luc-PC\\Luc, does not have access to the Adventure Works DW database, or the database does not exist." Source="Microsoft SQL Server 2005 Analysis Services" ErrorCode=-1055391743 StackTrace: at Microsoft.AnalysisServices.AdomdClient.AdomdConnection.XmlaClientProvider.Microsoft.AnalysisServices.AdomdClient.IDiscoverProvider.Discover(String requestType, IDictionary restrictions, DataTable table) at Microsoft.AnalysisServices.AdomdClient.ObjectMetadataCache.Discover(AdomdConnection connection, String requestType, ListDictionary restrictions, DataTable destinationTable, Boolean doCreate) at Microsoft.AnalysisServices.AdomdClient.ObjectMetadataCache.PopulateSelf() at Microsoft.AnalysisServices.AdomdClient.ObjectMetadataCache.Microsoft.AnalysisServices.AdomdClient.IObjectCache.Populate() at Microsoft.AnalysisServices.AdomdClient.CacheBasedNotFilteredCollection.PopulateCollection() at Microsoft.AnalysisServices.AdomdClient.CacheBasedNotFilteredCollection.get_Count() at Microsoft.AnalysisServices.AdomdClient.CubesEnumerator.MoveNext() at Microsoft.AnalysisServices.AdomdClient.CubeCollection.Enumerator.MoveNext() at blah blah... I've looked for a solution for the last 4+ hours and haven't had any success. Thanks in advance for any help. Luc

• WCF push to client through firewall?

  - by Sire

  See also How does a WCF server inform a WCF client about changes? (Better solution then simple polling, e.g. Coment or long polling) I need to use push-technology with WCF through client firewalls. This must be a common problem, and I know for a fact it works in theory (see links below), but I have failed to get it working, and I haven't been able to find a code sample that demonstrates it. Requirements: WCF Clients connects to server through tcp port 80 (netTcpBinding). Server pushes back information at irregular intervals (1 min to several hours). Users should not have to configure their firewalls, server pushes must pass through firewalls that have all inbound ports closed. TCP duplex on the same connection is needed for this, a dual binding does not work since a port has to be opened on the client firewall. Clients sends heartbeats to server at regular intervals (perhaps every 15 mins) so server knows client is still alive. Server is IIS7 with WAS. The solution seems to be duplex netTcpBinding. Based on this information: WCF through firewalls and NATs Keeping connections open in IIS But I have yet to find a code sample that works.. I've tried combining the "Duplex" and "TcpActivation" samples from Microsoft's WCF Samples without any luck. Please can someone point me to example code that works, or build a small sample app. Thanks a lot!
