• How to detect and configure an output with xrandr?

  - by ysap

  I have a DELL U2410 monitor connected to a Compaq 100B desktop equipped with an integrated AMD/ATI graphics card (AMD E-350). The installed O/S is Ubuntu 10.04 LTS. The computer is connected to the monitor via the DVI connection. The problem is that I cannot set the desktop resolution to the native 1920x1200. The maximum allowed resolution is 1600x1200. Doing some research I found about the xrandr utility. Unfortunately, when trying to use it I cannot configure it to the required resolution. First, it does not report the output name (which supposed to be DVI-0), saying default instead. Without it I cannot use the --fb option. The EDID utility seems to identify the monitor well. Here's the output from get-edid: # EDID version 1 revision 3 Section "Monitor" # Block type: 2:0 3:ff # Block type: 2:0 3:fc Identifier "DELL U2410" VendorName "DEL" ModelName "DELL U2410" # Block type: 2:0 3:ff # Block type: 2:0 3:fc # Block type: 2:0 3:fd HorizSync 30-81 VertRefresh 56-76 # Max dot clock (video bandwidth) 170 MHz # DPMS capabilities: Active off:yes Suspend:yes Standby:yes Mode "1920x1200" # vfreq 59.950Hz, hfreq 74.038kHz DotClock 154.000000 HTimings 1920 1968 2000 2080 VTimings 1200 1203 1209 1235 Flags "-HSync" "+VSync" EndMode # Block type: 2:0 3:ff # Block type: 2:0 3:fc # Block type: 2:0 3:fd EndSection but the xrandr -q command returns: Screen 0: minimum 640 x 400, current 1600 x 1200, maximum 1600 x 1200 default connected 1600x1200+0+0 0mm x 0mm 1600x1200 0.0* 1280x1024 0.0 1152x864 0.0 1024x768 0.0 800x600 0.0 640x480 0.0 720x400 0.0 When I try to set the resolution, I get: $ xrandr --fb 1920x1200 xrandr: screen cannot be larger than 1600x1200 (desired size 1920x1200) $ xrandr --output DVI-0 --auto warning: output DVI-0 not found; ignoring How can I set the screen resolution to 1920x1200? Why doesn't xrandr identify the DVI-0 output? Note that the same computer running Ubuntu version higher than 10.04 detects the correct resolution with no problems. On this machine I cannot upgrade due to some legacy hardware compatibility problems. Also, I don't see any optional screen drivers available in the Hardware Drivers dialog. ---- UPDATE: following the answer to this question, I got some advance. Now the required mode is listed in the xrandr -q list, but I can't switch to that mode. Using the Monitors applet (which now shows the new mode), I get the response that: The selected configuration for displays could not be applied. Could not set the configuration to CRTC 262. From the command line it looks like this: $ cvt 1920 1200 60 # 1920x1200 59.88 Hz (CVT 2.30MA) hsync: 74.56 kHz; pclk: 193.25 MHz Modeline "1920x1200_60.00" 193.25 1920 2056 2256 2592 1200 1203 1209 1245 -hsync +vsync $ xrandr --newmode "1920x1200_60.00" 193.25 1920 2056 2256 2592 1200 1203 1209 1245 -hsync +vsync $ xrandr -q Screen 0: minimum 640 x 400, current 1600 x 1200, maximum 1600 x 1200 default connected 1600x1200+0+0 0mm x 0mm 1600x1200 0.0* 1280x1024 0.0 1152x864 0.0 1024x768 0.0 800x600 0.0 640x480 0.0 720x400 0.0 1920x1200_60.00 (0x120) 193.0MHz h: width 1920 start 2056 end 2256 total 2592 skew 0 clock 74.5KHz v: height 1200 start 1203 end 1209 total 1245 clock 59.8Hz $ xrandr --addmode default 1920x1200_60.00 $ xrandr -q Screen 0: minimum 640 x 400, current 1600 x 1200, maximum 1600 x 1200 default connected 1600x1200+0+0 0mm x 0mm 1600x1200 0.0* 1280x1024 0.0 1152x864 0.0 1024x768 0.0 800x600 0.0 640x480 0.0 720x400 0.0 1920x1200_60.00 59.8 $ xrandr --output default --mode 1920x1200_60.00 xrandr: Configure crtc 0 failed Another piece of info (if it helps anyone): $ sudo lshw -c video *-display UNCLAIMED description: VGA compatible controller product: ATI Technologies Inc vendor: ATI Technologies Inc physical id: 1 bus info: pci@0000:00:01.0 version: 00 width: 32 bits clock: 33MHz capabilities: pm pciexpress msi bus_master cap_list configuration: latency=0 resources: memory:c0000000-cfffffff(prefetchable) ioport:f000(size=256) memory:feb00000-feb3ffff

• Enable Multi-Column Google Searches with a User Script

  - by Asian Angel

  Are you wanting to improve the search results view at Google and make better use of the webpage space? With a little user script magic you can make those search results look and fit better in your favorite browser. Note: This user script may conflict with the AutoPager extension if you have it installed in your favorite browser. Before Here is the standard single column view of search results at Google. Not too bad but the available space could certainly be better utilized. Note: For the purposes of our example we are using Google Chrome but this user script can be easily added to other browsers. After If you have never installed a user script in Chrome before it is just as simple as the regular extensions at the official Google website. Here you can see the details for the user script we are installing. Notice that you can view the source code if desired. To add the user script to Chrome click on “Install”. Once you start the install process you will see an intermediary message asking if you wish to continue in the lower left corner of your browser. Click “Continue” to move to the next step in the install process. From this point on the install process is practically identical to the official extensions. You can see the final confirmation window here…click “Install” to finish adding the user script to Chrome. As with regular extensions you will see a post-install message in the upper right corner. So, what does a user script look like in the “Extensions Page”? You can see the user script entry here…outside of an icon it looks rather identical to a normal extension. After refreshing the search page shown above we now have two columns of search results (default setting). This looks much much better than a single column view and there is little to no page scrolling required now. To switch to a three column view simply use the keyboard shortcut “Alt + 3”. To return to a single column view use “Alt + 1” and for the default two column view use “Alt + 2”. Three keyboard shortcuts for three different views…definitely a good thing. Note: On our test system we needed to use the number keys at the top of our keyboard to switch views…this is most likely the result of unique settings on our test system. Conclusion If you are wanting a better viewing experience when conducting searches at Google then this user script will make a very nice addition to your favorite browser. For those using Firefox you can add user scripts with the Greasemonkey & Stylish extensions. Using Opera Browser? See our how-to for adding user scripts to Opera here.

• IE9, HTML5 and truck load of other stuff happening around the web

  - by Harish Ranganathan

  First of all, I haven’t been updating this blog as regularly as it used to be.  Primarily, due to the fact was I was visiting a lot of cities talking about SharePoint, Web Matrix, IE9 and few other stuff.  IE9 is my new found love and I simply think we have done great work in improving the browser and browsing experiences for our users. This post would talk about IE, general things happening around the web and few misconceptions around IE (I had earlier written about IE8 and common myths When you think about the way web has transformed, its truly amazing.  Rewind back to late 90s and early 2000s, web was a luxury.  There were lot of desktop applications running around and web applications was starting to pick up.  Primarily reason was not a lot of folks were into web development and the areas of web were confined to HTML and JavaScript.  CSS was around here and there but no one took it so seriously.  XML, XSLT was fast picking up and contributed to decent web development techniques. So as a web developer all we had to worry about was, building good looking websites which worked well with IE6 and occasionally with Safari.  Firefox was  not even in the picture then and so was Chrome.  But with the various arms of W3C consortium and other bodies working actively on stuff like CSS, SVG and XHTML, few more areas came into picture when it comes to browsers supporting standards.  IE6 for sure wasn’t up to the speed and the main issue we were tackling then was privacy and piracy.  We did invest a lot of our efforts to curb piracy and one of the steps into it was that, IE7 the next version of IE would install only on genuine windows machines.  What this means, is that, people who were running pirated windows xp knowingly/unknowingly could not install IE7 and the limitations of IE6 really hurt them.  One more thing of importance is that, if you were running pirated windows, lots of chances that you didn’t get the security updates and thereby were vulnerable to run viruses/trojans on your system. Many of them actually block using IE in the first place and make it difficult to browse.  SP2 came as a big boon but again was there only for genuine windows machines. With Firefox coming as a free install and also heavily pushed by Google then, it was natural that people would try an alternative.  By then, we had started working on IE8 supporting the best standards (note HTML5, CSS 2.1 and other specs were then work in progress.  they are still) Later, Google in their infinite wisdom realized that with Firefox they were going nowhere and they released Chrome.  Now, they heavily push Chrome even for Firefox users, which is natural since its their browser. In the meanwhile, these browsers push their updates as mandatory and therefore have a very short lifecycle to add enhancements and support for stuff like CSS etc., Meanwhile, when IE8 came out, it really was the best standards supported browser and a lot of people saw our efforts in improving our browser. HTML5 is the buzz word in the industry and there is a lot of noise being made by many browsers claiming their support for it.  IE8 doesn’t have much support for HTML5.  But, with IE9 Beta, we have great support for many of HTML5 specifications.  Note that, HTML5 is still work under progress and one of the board of members working on the spec has mentioned that these specs might change and relying on them heavily is dangerous.  But, some of the advances such as video tag, etc., are indeed supported in IE9 Beta.  IE9 Beta also has full hardware acceleration support which other browsers don’t have. IE8 had advanced security features such as smartscreen filter, in-private browsing, anti-phishing and a lot of other stuff.  IE9 builds on top of these with the best in town security standards as well as support for HTML5, CSS3, Hardware acceleration, SVG and many other advancements in browser.  Read more at http://www.beautyoftheweb.com/#/highlights/html5  To summarize, IE9 Beta is really innovative and you should try it to believe what it provides.  You can visit http://www.beautyoftheweb.com/  to install as well as read more on this. Cheers !!!

• Use Your Favorite Wallpapers in Windows 7 Starter Edition

  - by Asian Angel

  If you have Windows 7 Starter Edition installed on your netbook, the default wallpaper can get old. If you are tired of looking at the default wallpaper, then join us today as we look at changing it with Oceanis Change Background Windows 7. Special Notes This information is quoted directly from the website and needs to be kept in mind when using Oceanis Change Background Windows 7: If the Oceanis Change Background Windows 7 program no longer works properly after installing some Windows Updates, then uninstall and reinstall the Oceanis Change Background Windows 7 program to have it run properly again. If you ever do an in-place upgrade to another higher level edition of Windows 7 in the future, then be sure to uninstall this Oceanis Change Background Windows 7 program first to avoid incompatibility issues with it in the new edition of Windows 7. It was designed to only work in Windows 7 Starter edition. Before There it is…the default wallpaper everyone with the Starter Edition gets stuck with. Some people may not mind it, but if you are one of the people who really wants something different then get ready to rejoice. After The install file for Oceanis is contained in a zip file so you will need to unzip it to get started. The install process is quick and simple but you will need to do a system restart afterwards. Once you have restarted your computer this is what your screen will look like…do not panic and think that this is all there is to it. This is just the Starter Screen and can be easily changed… Note: Oceanis will auto-start with Windows each time. Using either the Desktop Icon or the Start Menu Entry, open up the Oceanis Main Window. You will see the set of four default wallpapers shown here. At this point the best thing to do is browse for the appropriate folder where you have all of those wonderful new wallpapers just waiting to be used. Note: We found Stretch to be the best Picture Position setting on our system. For our example we had three ready and waiting. We decided to try out the Wallpaper Slideshow feature first. We chose a time frame and saved our changes. Here are our three wallpapers as they switched through. This can be much more interesting than the default wallpaper. There was only one quirk that we encountered while using the Slideshow Setting. On occasion if we minimized a non-maximized window there would be a leftover partial image in place of the window. Our suggestion? Go with one wallpaper at a time and the settings shown below. These are the settings that we had terrific luck with…Only one picture selected, Picture Position = Stretch, & Change Picture Every = Every Day. Using these settings, the Starter Edition acted just like any of the other editions with regard to wallpaper management. Conclusion If you have grown tired of looking at the default wallpaper in Windows 7 Starter Edition then you will certainly appreciate what Oceanis Change Background Windows 7 can do to fix that problem.

• [Silverlight] How to watermark a WriteableBitmap with a text

  - by Benjamin Roux

  Hello, In my current project, I needed to watermark a WriteableBitmap with a text. As I couldn’t find anything I decided to create a small extension method to do so. public static class WriteableBitmapEx { /// <summary> /// Creates a watermark on the specified image /// </summary> /// <param name="input">The image to create the watermark from</param> /// <param name="watermark">The text to watermark</param> /// <param name="color">The color - default is White</param> /// <param name="fontSize">The font size - default is 50</param> /// <param name="opacity">The opacity - default is 0.25</param> /// <param name="hasDropShadow">Specifies if a drop shadow effect must be added - default is true</param> /// <returns>The watermarked image</returns> public static WriteableBitmap Watermark(this WriteableBitmap input, string watermark, Color color = default(Color), double fontSize = 50, double opacity = 0.25, bool hasDropShadow = true) { var watermarked = GetTextBitmap(watermark, fontSize, color == default(Color) ? Colors.White : color, opacity, hasDropShadow); var width = watermarked.PixelWidth; var height = watermarked.PixelHeight; var result = input.Clone(); var position = new Rect(input.PixelWidth - width - 20 /* right margin */, input.PixelHeight - height, width, height); result.Blit(position, watermarked, new Rect(0, 0, width, height)); return result; } /// <summary> /// Creates a WriteableBitmap from a text /// </summary> /// <param name="text"></param> /// <param name="fontSize"></param> /// <param name="color"></param> /// <param name="opacity"></param> /// <param name="hasDropShadow"></param> /// <returns></returns> private static WriteableBitmap GetTextBitmap(string text, double fontSize, Color color, double opacity, bool hasDropShadow) { TextBlock txt = new TextBlock(); txt.Text = text; txt.FontSize = fontSize; txt.Foreground = new SolidColorBrush(color); txt.Opacity = opacity; if (hasDropShadow) txt.Effect = new DropShadowEffect(); WriteableBitmap bitmap = new WriteableBitmap((int)txt.ActualWidth, (int)txt.ActualHeight); bitmap.Render(txt, null); bitmap.Invalidate(); return bitmap; } } For this code to run, you need the WritableBitmapEx library. As you can see, it’s quite simple. You just need to call the Watermark method and pass it the text you want to add in your image. You can also pass optional parameters like the color, the opacity, the fontsize or if you want a drop shadow effect. I could have specify other parameters like the position or the the font family but you can change the code if you need to. Here’s what it can give Hope this helps.

• EPM 11.1.2.2 Architecture: Financial Performance Management Applications

  - by Marc Schumacher

   Financial Management can be accessed either by a browser based client or by SmartView. Starting from release 11.1.2.2, the Financial Management Windows client does not longer access the Financial Management Consolidation server. All tasks that require an on line connection (e.g. load and extract tasks) can only be done using the web interface. Any client connection initiated by a browser or SmartView is send to the Oracle HTTP server (OHS) first. Based on the path given (e.g. hfmadf, hfmofficeprovider) in the URL, OHS makes a decision to forward this request either to the new Financial Management web application based on the Oracle Application Development Framework (ADF) or to the .NET based application serving SmartView retrievals running on Internet Information Server (IIS). Any requests send to the ADF web interface that need to be processed by the Financial Management application server are send to the IIS using HTTP protocol and will be forwarded further using DCOM to the Financial Management application server. SmartView requests, which are processes by IIS in first row, are forwarded to the Financial Management application server using DCOM as well. The Financial Management Application Server uses OLE DB database connections via native database clients to talk to the Financial Management database schema. Communication between the Financial Management DME Listener, which handles requests from EPMA, and the Financial Management application server is based on DCOM.  Unlike most other components Essbase Analytics Link (EAL) does not have an end user interface. The only user interface is a plug-in for the Essbase Administration Services console, which is used for administration purposes only. End users interact with a Transparent or Replicated Partition that is created in Essbase and populated with data by EAL. The Analytics Link Server deployed on WebLogic communicates through HTTP protocol with the Analytics Link Financial Management Connector that is deployed in IIS on the Financial Management web server. Analytics Link Server interacts with the Data Synchronisation server using the EAL API. The Data Synchronization server acts as a target of a Transparent or Replicated Partition in Essbase and uses a native database client to connect to the Financial Management database. Analytics Link Server uses JDBC to connect to relational repository databases and Essbase JAPI to connect to Essbase.  As most Oracle EPM System products, browser based clients and SmartView can be used to access Planning. The Java based Planning web application is deployed on WebLogic, which is configured behind an Oracle HTTP Server (OHS). Communication between Planning and the Planning RMI Registry Service is done using Java Remote Message Invocation (RMI). Planning uses JDBC to access relational repository databases and talks to Essbase using the CAPI. Be aware of the fact that beside the Planning System database a dedicated database schema is needed for each application that is set up within Planning.  As Planning, Profitability and Cost Management (HPCM) has a pretty simple architecture. Beside the browser based clients and SmartView, a web service consumer can be used as a client too. All clients access the Java based web application deployed on WebLogic through Oracle HHTP Server (OHS). Communication between Profitability and Cost Management and EPMA Web Server is done using HTTP protocol. JDBC is used to access the relational repository databases as well as data sources. Essbase JAPI is utilized to talk to Essbase.  For Strategic Finance, two clients exist, SmartView and a Windows client. While SmartView communicates through the web layer to the Strategic Finance Server, Strategic Finance Windows client makes a direct connection to the Strategic Finance Server using RPC calls. Connections from Strategic Finance Web as well as from Strategic Finance Web Services to the Strategic Finance Server are made using RPC calls too. The Strategic Finance Server uses its own file based data store. JDBC is used to connect to the EPM System Registry from web and application layer.  Disclosure Management has three kinds of clients. While the browser based client and SmartView interact with the Disclosure Management web application directly through Oracle HTTP Server (OHS), Taxonomy Designer does not connect to the Disclosure Management server. Communication to relational repository databases is done via JDBC, to connect to Essbase the Essbase JAPI is utilized.

• SharePoint Content and Site Editing Tips

  - by Bil Simser

  A few content management and site editing tips for power users on this bacon flavoured unicorn morning. The theme here is keep it clean!Write "friendly" email addressesRemember it's human beings reading your content. So seeing something like "If you have questions please send an email to [email protected]" breaks up the readiblity. Instead just do the simple steps of writing the content in plain English and going back, highlighting the name and insert a link (note: you might have to prefix the link with mailto:[email protected]). It makes for a friendlier looking page and hides the ugliness that are sometimes in email addresses.Use friendly column and list namesThis is a big pet peeve of mine. When you first create a column or list with spaces the internal name is changed. The display name might be "My Amazing List of Animals with Large Testicles" but the internal (and link) name becomes "My_x00x20_Amazing_x00x20_List_x00x20_of_x00x20_Animals_x00x20_with_x00x20_Large_x00x20_Testicles". What's worse is if you create a publishing page named "This Website is Fueled By a Dolphin's Spleen". Not only is it incorrect grammar, but the apostrophe wreaks havoc on both the internal name for the list (with lots of crazy hex codes) as well as the hyperlink (where everything is uuencoded). Instead create the list with a distinct and compact name then go back and change it to whatever you want. The end result is a better formed name that you can both script and access in code easier.Keep your Views CleanWhen you add a column to a list or create a new list the default is to add it to the default view. Do everyone a favour and don't check this box! The default view of a list should be something similar to the Title field and nothing else. Keep it clean. If you want to set a defalt view that's different, go back and create one with all the fields and filtering and sorting columns you want and set it as default. It's a good idea to keep the original AllItems.aspx (note the lack of space in the filename!) easy and unfiltered. It's also a good idea to keep your column count down in views. Don't let every column be added by default and don't add every column just because you can. Create separate views for distinct responsibilities and try to keep the number of columns down to a single screen to prevent horizontal scrolling.Simple NavigationThe Quick Launch is a great tool for navigating around your site but don't use the default of adding all lists to it. Uncheck that box and keep navigation simple. Create custom groupings that make sense so if you don't have a site with "Documents and Lists" but "Reports and Notices" makes more sense then do it. Also hide internal lists from the Quick Launch. For example, if most users don't need to see all the lookup tables you might have on a site don't show them. You can use audience filtering on the Quick Launch if you want to hide admin items from non-admin users so consider that as an option.Enjoy!

• webview.loadUrl() problem in android?

  Hi guys, I am loading a URL whose datatype is String in a WebView. Using something like: webview.loadUrl(string_variable); but it is automatically redirected to the browser. I got this in my LOGCAT, 02-13 14:11:08.586: INFO/ActivityManager(5Cool: Displayed activity com.example.brown/.Bru_Press_MostRecent_ArticleView: 2583 ms (total 2583 ms) 02-13 14:11:09.376: INFO/ActivityManager(5Cool: Starting activity: Intent { act=android.intent.action.VIEW cat=[android.intent.category.BROWSABLE] dat=http://mobile.twitter.com/brownuniversity/statuses/8681812931 cmp=com.android.browser/.BrowserActivity (has extras) } 02-13 14:11:09.506: INFO/ActivityManager(5Cool: Start proc com.android.browser for activity com.android.browser/.BrowserActivity: pid=285 uid=10014 gids={3003, 1015}

• ASP.NET Unit Testing - WatiN and Windows 7 / Internet Explorer 8

  - by tyndall

  Any tricks in getting WatiN to run on Win7/IE8? My code: browser = new IE(); browser.GoTo("http://testserver"); browser.TextField(Find.ByName("txtUser")).TypeText("tyndall"); The third line never really runs and I get an error back: System.Runtime.InteropServices.COMException : The RPC server is unavailable. (Exception from HRESULT: 0x800706BA) The second line seems to run. IE8 appears and is navigated to the correct URL.

• Headers to set for AJAX calls in a custom webserver

  - by ErJab

  I'm writing a custom web server. When I enter the URL of my server in the browser, I get the sample text I write out to the socket in my browser correctly. This is the HTTP response that I write: HTTP/1.1 200 OK\r\n Server: My Server\r\n Date: Blah\r\n \r\n This is some sample text. This appears in my browser correctly when I connect directly to the server entering the URL. However, if I use Ajax (jQuery) to access the same URL and then set the innerHTML of an element on the HTML page, I do not get any data printed. Is there any other header I need to set on my web server so that the browser's XMLHttpRequest object detects the response?

• NHibernate.MappingException (no persister for) weirdness

  - by Berryl

  The weird part being that I have other tests that validate the mapping and even the method being called (Nhib session.SaveOrUpdate) that run just fine. The entire exception is below. Here is some debug output from a test that does work: Item type: Domain.Model.Projects.Project item: 007-00-056 ATM Machine Replacement Is transient: True Id: 0 NHibernate: INSERT INTO Projects (Code, Description) VALUES (@p0, @p1); select insert_rowid();@p0 = '007-00-056', @p1 = 'ATM Machine Replacement' Here is the same debug output before the exception: Item type: Smack.ConstructionAdmin.Domain.Model.Projects.Project item: 006-00-023 Refinish Casino Chairs Is transient: True Id: 0 The two tests are different in that the one that works is just testing the repository, and saving in memory test data. The failing one is saving data that has been converted from a legacy db (which has it's own session). The repository is also a replacement design for a different IProjectRepsitory that worked fine doing this, so the new repository is also a likely suspect here. Does anyone see what I'm missing or have some questions to narrow it down? Cheers, Berryl === the Exception trace ===== failed: NHibernate.MappingException : No persister for: Domain.Model.Projects.Project at NHibernate.Impl.SessionFactoryImpl.GetEntityPersister(String entityName) at NHibernate.Impl.SessionImpl.GetEntityPersister(String entityName, Object obj) at NHibernate.Event.Default.AbstractSaveEventListener.SaveWithGeneratedId(Object entity, String entityName, Object anything, IEventSource source, Boolean requiresImmediateIdAccess) at NHibernate.Event.Default.DefaultSaveOrUpdateEventListener.SaveWithGeneratedOrRequestedId(SaveOrUpdateEvent event) at NHibernate.Event.Default.DefaultSaveEventListener.SaveWithGeneratedOrRequestedId(SaveOrUpdateEvent event) at NHibernate.Event.Default.DefaultSaveOrUpdateEventListener.EntityIsTransient(SaveOrUpdateEvent event) at NHibernate.Event.Default.DefaultSaveEventListener.PerformSaveOrUpdate(SaveOrUpdateEvent event) at NHibernate.Event.Default.DefaultSaveOrUpdateEventListener.OnSaveOrUpdate(SaveOrUpdateEvent event) at NHibernate.Impl.SessionImpl.FireSave(SaveOrUpdateEvent event) at NHibernate.Impl.SessionImpl.Save(Object obj) NHibernate\Repository\NHibRepository.cs(40,0): at Core.Data.NHibernate.Repository.NHibRepository`1.Add(T item) Repositories\ProjectRepository.cs(30,0): at Data.Repositories.ProjectRepository.SaveAll(IEnumerable`1 projects) LegacyConversion\LegacyBatchUpdater.cs(20,0): at Data.LegacyConversion.LegacyBatchUpdater.ConvertOpenLegacyProjects(ILegacyProjectDao legacyProjectDao, IProjectRepository greenProjectRepository) Data\Brownfield\ProjectBatchUpdate_SQLiteTests.cs(31,0): at .Tests.Data.Brownfield.ProjectBatchUpdate_SQLiteTests.Test()

• SSRS 2008: is it possible to make a report parameter NOT query-based for some linked report?

  - by Stefan Mohr

  I suspect the answer is no, but here goes.. I'm using the WebForms Report Viewer on a public-facing website to allow users to report on themselves or their users (if the user is an admin user). A report has a parameter called Users where an admin can pick a user from the list and generate a report from it. Mundane users can also view this report, but I programmatically create a linked report for each user and set the UserID value to their ID so they can only view themselves. This works well except that the UserID parameter is query-based, and not every user is visible in the list using default settings (the user list is based off date range parameters can provide, and only users we consider 'active' during the date range are visible). This is blowing up for mundane users that are not active for the default date range (which is the previous month). I suspect the flow of execution is something like this: Report loads with default parameters The linked report rules are now applied and the value of the UserID is overridden with the ID in the linked report UserID field is now hidden to prevent the user from changing it SSRS can't find the UserID default value in the query results (that I didn't even want it to run) so it displays an error The 'UserID' parameter is missing a value Through some testing I've found a perfect correlation between users not inside the default date range and users who can't view the report. Can anyone suggest a way to make the report usable for those users that aren't in the default list? The reports are created programmatically so I do have a fair bit of control over the situation. I would love to simply be able to mark a parameter in a linked report as no longer being query-based, but those properties are all read-only. I really, really don't want to have to create duplicate reports to accommodate these users but I'm at a bit of a loss right now. Any suggestions are greatly appreciated!

• Where are the factory_girl records?

  - by gmile

  I'm trying to perform an integration test via Watir and RSpec. So, I created a test file within /integration and wrote a test, which adds a test user into a base via factory_girl. The problem is — I can't actually perform a login with my test user. The test I wrote looks as following: ... before(:each) @user = Factory(:user) @browser = FireWatir::Firefox.new end it "should login" @browser.text_field(:id, "username").set(@user.username) @browser.text_field(:id, "password").set(@user.password) @browser.button(:id, "get_in").click end ... As I'm starting the test and see a "performance" in browser, it always fires up a Username is not valid error. I've started an investigation, and did a small trick. First of all I've started to have doubts if the factory actually creates the user in DB. So after the immediate call to factory I've put some puts User.find stuff only to discover that the user is actually in DB. Ok, but as user still couldn't have logged in I've decided to see if he's present in DB with my own eyes. I've added a sleep right after a factory call, and went to see what's in the DB at the moment. I was crushed to see that the user is actually missing there! How come? Still, when I'm trying to output a user within the code, he is actually being fetched from somewhere. So where does the records, made by factory_girl within a runtime lie? Is it test or dev DB? I don't get it. I've 10 times checked if I'm running my Mongrel in test mode (does it matter? I think it does, as I'm trying to tun an integration test) and if my database.yml holds the correct connection specific data. I'm using an authlogic, if that can give any clue (no, putting activate_authlogic doesn't work here).

• multiple stateful iframes per page will overwrite JSESSIONID?

  - by Nikita

  Hello, Looking for someone to either confirm or refute my theory that deploying two iframes pointing to two different stateful pages on the same domain can lead to JSESSIONIDs being overwritten. Here's what I mean: Setup suppose you have two pages that require HttpSession state (session affinity) to function correctly - deployed at http://www.foo.com/page1 and http://www.foo.com/page2 assume www.foo.com is a single host running a Tomcat (6.0.20, fwiw) that uses JSESSIONID for session id's. suppose these pages are turned into two iframe widgets to be embedded on 3rd party sites: http://www.site.com/page1" / (and /page2 respectively) suppose there a 3rd party site that wishes to place both widgets on the same page at http://www.bar.com/foowidgets.html Can the following race condition occur? a new visitor goes to http://www.bar.com/foowidgets.html browser starts loading URLs in foowidgets.html including the two iframe 'src' URLs because browsers open multiple concurrent connections against the same host (afaik up to 6 in chrome/ff case) the browser happens to simultaneously issue requests for http://www.foo.com/page1 and http://www.foo.com/page2 The tomcat @ foo.com receives both requests at about the same time, calls getSession() for the first time (on two different threads) and lazily creates two HttpSessions and, thus, two JSESSIONIDs, with values $Page1 and $Page2. The requests also stuff data into respective sessions (that data will be required to process subsequent requests) assume that the browser first receives response to the page1 request. Browser sets cookie JSESSIONID=$Page1 for HOST www.foo.com next response to the page2 request is received and the browser overwrites cookie JSESSIONID for HOST www.foo.com with $Page2 user clicks on something in 'page1' iframe on foowidgets.html; browser issues 2nd request to http://www.foo.com/page1?action=doSomethingStateful. That request carries JSESSIONID=$Page2 (and not $Page1 - because cookie value was overwritten) when foo.com receives this request it looks up the wrong HttpSession instance (because JSESSIONID key is $Page2 and NOT $Page1). Foobar! Can the above happen? I think so, but would appreciate a confirmation. If the above is clearly possible, what are some solutions given that we'd like to support multiple iframes per page? We don't have a firm need for the iframes to share the same HttpSession, though that would be nice. In the event that the solution will still stipulate a separate HttpSession per iframe, it is - of course - mandatory that iframe 1 does not end up referencing httpSession state for iframe 2 instead of own. off top of my head I can think of: map page1 and page2 to different domains (ops overhead) use URL rewriting and never cookies (messes up analytics) anything else? thanks a lot, -nikita

• Zend Framework subdomain+subfolder router rewrite problem

  - by zf_novice

  I'm new to Zend Framwork and this is an issue I've been struggling for several hours already... I'm trying to chain Hostname and standard Route in order to get url with subdomain+subfolders ie.: http:// lang.mydomain.com/myapplication/public/controller http:// lang.mydomain.com/myapplication/public/controller/action (sorry for the empty space in the address, this site won't allow links) Basically what I have done in Bootstrap is: // add language to default route $routePath = new Zend_Controller_Router_Route( ':controller/:action/*', array('controller'=>'index','action' => 'index','module'=>'default') ); $routeHostname = new Zend_Controller_Router_Route_Hostname( ':lang.mydomain.com', array('lang'=>$lang) ); $frontController = $this->getResource('FrontController'); $router = $frontController->getRouter(); $router->addRoute('default', $routeHostname->chain($routePath)) $frontController->setRouter($router); it finds the route ok, but every time I generate url in view or layout by $this-url() <?php echo $this->url( array( 'controller'=> 'guestbook', 'action' => 'sign', 'lang' => Zend_Registry::get('lang'), ), 'default', true) ?>"> I get http:// lang.mydomain.com/controller instead of http:// lang.mydomain.com/myapplication/public/controller I've been trying to set baseUrl on front controller but no luck... Also I've tried the static route with myapplication/public or following standard route: 'myapplication/public/:controller/:action/*' - it result with "An error occurred Page not found Exception information: Message: No route matched the request" and empty request Is there any way to assembly subdomain with subfolder in Zend Framwork?? EDIT: I changed above to: $frontController->setBaseUrl('.'); // add language to default route $routePath = new Zend_Controller_Router_Route( 'quickstart/public/:controller/:action/*', array( 'controller'=>'index', 'action' => 'index', 'module'=>'default', ) ); and it works form me, although I'm not sure whether it's been correct approach...

• emacs indentation problem

  - by Gauthier

  I'm really trying to switch to emacs, but learning to setup the environment is a real pain. Everybody says it's worth it, so I just continue. I want my c code to be implemented that way: if(asdf) { asdr = 1; } Depending on the current standard (I know, don't get me started), could be: if(asdf) { asdr = 1; } I can't seem to change the indentation size from 2, it always looks like the GNU standard: if(asdf) { asdr = 1; } , which I dislike. Here is what I have put in my .emacs: ; Warn in C for while();, if(x=0), ... (global-cwarn-mode 1) ; no electric mode in c (c-toggle-electric-state -1) ; indent the current line only if the cursor is at the beginning of the line (setq-default c-tab-always-indent nil) (setq-default c-indent-level 4) (setq-default tab-width 4) (setq-default indent-tabs-mode nil) (setq-default c-basic-offset 4) (setq-default c-basic-indent 4) ; These commands I read about on the web, but they don't work? ;(highlight-tabs) ;(highlight-trailing_whitespace) This did not help, I have still the GNU indent. Anyone?

• Unnecessary scroll bars appearing in IE8

  - by Abhishek Jain

  Hi, In my web app there is a page(ChildPage) which is actually contained in an iframe element of another page(ParentPage). This ChildPage has its contents placed in ContentPlaceHolder of a MasterPage. <div id="DivScroll" runat="server" style="overflow-y: auto; overflow-x: auto; width: 100%; height: 100%;"> <asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server"> </asp:ContentPlaceHolder> </div> As apparent in the code, contents of ChildPage are scrollable in the div containing it. There is never the need for the scroll bars of browser to appear and it is working this way till IE7. In IE8 browser scrollbras are appearing due to the presence of the following div in ChildPage. <div class="ReadOnlyFlat" id="Div1" style="z-index: 100; visibility: hidden; overflow: auto; width: 100%; position: absolute; height: 300px" runat="server" ms_positioning="FlowLayout"> <radA:RadAjaxPanel ID="RadAjaxPanelA" EnableOutsideScripts="True" runat="server"> <radT:RadTreeView ID="RadTreeView2" TabIndex="1" runat="server" Skin="web20"> <NodeTemplate> <asp:Label ID="Label2" runat="server">Label</asp:Label> <asp:Label ID="Label4" runat="server" Width="10px"></asp:Label> <asp:Label ID="Label3" runat="server" ForeColor="#FF8000" Font-Bold="True">Label</asp:Label> </NodeTemplate> </radT:RadTreeView> </radA:RadAjaxPanel> What actually happens in IE8 is as follows: The above div Div1 is diaplyed on the click of an ImageButton. On the page load this ImageButton is present on the bottom of the page. In this case IE8 shows browser's vertical scrollbar due to height of Div1. When I scroll DivScroll shown in first code snippet, the ImageButton moves up. When the ImageButton is moved sufficiently up so that it is above the bottommost part of page by more than 300px(i.e, the height of Div1) and if I click the ImageButton, the browser's vertical scrollbars disappear. Browser's vertical scrollbar appears in case the distance between ImageButton and the bottom most part of page is less than height of Div1 and disappears when the distance is more than height of Div1. I need that the browser's vertical scrollbar never appears. Please Help.

• Java,Tomcat,Sessions - JSessionId disappear

  - by Bob

  Hi, I'm having a problem with java sessions. I'm developing a simple web app, where I have to use sessions and session attributes. Everything is fine until I close my browser. When I close my browser the JSessionId disappears. Here's my code: request.getSession().setMaxInactiveInterval(30*60); //it's 30 minutes request.getSession().setAttribute("someinteger", 10); It works great, but when I shut down the browser, and reopen it I can't find the jsessionId (before I closed the browser I could find it in the 'localhost' section). The strange thing is I can still find the "someinteger" cookie. What is the problem? What am I doing wrong? I'm using this, too: link text, and it shows that JSESSIONID cookie expires : "SESSION", and "someinteger" expires in 30 minutes Thanks in advance.
