• how to pass vector of string to foo(char const *const *const)?

  - by user347208

  Hi, This is my first post so please be nice. I searched in this forum and googled but I still can not find the answer. This problem has bothered me for more than a day, so please give me some help. Thank you. I need to pass a vector of string to a library function foo(char const *const *const). I can not pass the &Vec[0] since it's a pointer to a string. Therefore, I have an array and pass the c_str() to that array. The following is my code (aNames is the vector of string): const char* aR[aNames.size()]; std::transform(aNames.begin(), aNames.end(), aR, boost::bind(&std::string::c_str, _1)); foo(aR); However, it seems it causes some undefined behavior: If I run the above code, then the function foo throw some warnings about illegal characters ('èI' blablabla) in aR. If I print aR before function foo like this: std::copy(aR, aR+rowNames.size(), std::ostream_iterator<const char*>(std::cout, "\n")); foo(aR); Then, everything is fine. My questions are: Does the conversion causes undefined behavior? If so, why? What is the correct way to pass vector of string to foo(char const *const *const)? Thank you very much for your help!

• PHP dynamic Page-level DocBlocks

  - by Obmerk Kronen

  I was wondering if there is a way to interact with the Page-level DocBlocks. My question is more specifically about wordpress plugin development, but this question has arised also in a non-wordpress environments. The reason is mainly the possibility to easily change VERSIONS and names throughout a large project with maybe a constant definition - but that will reflect also in the docblock.. The following example Docblock is from a wordpress plugin I write - /* Plugin Name: o99 Auxilary Functions v0.4.7 Plugin URI: http://www.myurl.com Description: some simple description that nobody reads. Version: 0.4.7 Author: my cool name Author URI: http://www.ok-alsouri.com */ Is there a way to transform it into : $ver = '0.4.7'; $uri = 'http://www.myurl.com'; $desc = 'some simple description that nobody reads.'; $mcn = 'my cool name'; etc.. etc.. /* Plugin Name: o99 Auxilary Functions ($ver) Plugin URI: ($uri) Description: ($desc) Version: ($ver) Author: ($mcn) Author URI: ($$uri) */ obviously for echo to work I would need to break the docblock itself, and I can not WRITE the docblock directly into it´s own file . In shorts : can I "generate" a docblock with php itself somehow (I would think that the answer is - "no" for the page itself.. But maybe I am wrong and someone has some neat hack :-) ) Is that even possible ?

• Regex preg_match issue with commas

  - by Serge Sf

  This is my code to pre_match when an amount looks like this: $ 99.00 and it works if (preg_match_all('/[$]\s\d+(\.\d+)?/', $tout, $matches)) { $tot2 = $matches[0]; $tot2 = preg_replace("/\\\$/", '', $tot2);} I need to do the same thing for a amount that looks like this (with a comma): $ 99,00 Thank you for your help (changing dot for comma do not help, there is an "escape" thing I do not understand... Idealy I need to preg_match any number that looks like an amount with dot or commas and with or without dollar sign before or after (I know, it's a lot to ask :) since on the result form I want to scan there are phone and street numbers... UPDATE (For some reason I cannot comment on replies) : To test properly, I need to preg_replace the comma by a dot (since we are dealings with sums, I don't think calculations can be done on numbers with commas in it). So to clarify my question, I should say : I need to transform, let's say "$ 200,24" to "200.24". (could be amounts bettween 0.10 to 1000.99) : $tot2 = preg_replace("/\\\$/", '', $tot2);} (this code just deals with the $ (it works), I need adaptation to deal also with the change of (,) for (.))

• rotating UITableViewController manually

  - by lope

  Hi there, I am trying to do something I am not really sure is possible :) I have application that is in portrait mode and doesn't react to device rotation. Almost all parts of app work best in portrait so I disabled autorotation. But one part should be viewed in landscape. I just drawed my view rotated by 90 degrees and with this forced user to rotate device (again no autorotation). Everything was ok until I added UITableViewController that is invoked from this (and only from this) rotated view. Table view is of course in portrait mode, so user has to rotate device again, which is not really user friendly experience. My problem is, how to manually rotate table view so it is in landscape mode without using autorotation feature. I was able to rotate it using transform, but I can't position it properly. Is this right way of doing this or did I missed something that would make this trivial task? I don't want to use autorotation because both part are pretty separated from each other and each of them would be almost useless in other's mode

• UIView rotate and than move

  - by user1790354

  I have problem with rotating and moving image (UIView). If I use this for rotate: [UIView beginAnimations: @"rotate" contex: nil]; [UIView setAnimationDuration: 1]; [UIView setAnimationBeginsFromCurrentState: YES]; [UIView setAnimationCurve: UIViewAnimationCurveLinear]; spaceShip.transform = CGAffineTransformMakeRotation (angle); // spaceShip is the UIView [UIView commitAnimations]; And this to move: [UIView beginAnimations: @"move" contex: nil]; [UIView setAnimationDuration: 1]; [UIView setAnimationBeginsFromCurrentState: YES]; [UIView setAnimationCurve: UIViewAnimationCurveLinear]; spaceShip.center = destanation // destanation is a point where user tap [UIView commitAnimations]; It's working well one at a time. But together this two animations don't work. Space Ship is rotating, but does not move in direction. Where my mistake? P.S. Early I have specify anchor point (0.5, 0.5). But when I rotate image it coordinates is changing.

• Data transformation question

  - by tkm

  I have data composed of a list of employers and a list of workers. Each has a many-to-many relationship with the other (so an employer can have many workers, and a worker can have many employers). The way the data is retrieved (and given to me) is as follows: each employer has an array of workers. In other words: employer n has: worker x, worker y etc. So I have a bunch of employer objects each containing an array of workers. I need to transform this data (and basically invert the relationship). I need to have a bunch of worker objects, each containing and array of employers. In other words: worker x has: employer n1, employer n2 etc. The context is hypothetical so please don't comment on why I need this or why I am doing it this way. I would really just like help on the algorithm to perform this transformation (there isn't that much data so I would prefer readability over complex optimizations which reduce complexity). (Oh and I am using Java, but pseudocode would be fine). Thanks!

• How to improve my software project's speed?

  - by Blitzkr1eg

  I'm doing a school software project with my class mates in Java. We store the info on a remote db. When we start the application we pull all the information from the database and transform it into objects to use in our application (using java sql statemens). In the application we edit some of these objects and then when we exit the application we save or update information in the database using Hibernate. As you see we dont use Hibernate for pulling in information, we use it just for saving and updating. We have 2, but very similar problems. The loading of object(when we start the app) and the saving of objects(with Hibernate) in the db(when closing the app) is taking too much time. And our project its not a huge enterprise application, its a quite small app, we just manage some students, teachers, homeworks and tests. So our db is also very very small. How could we increase performance ? later edit: if we use a local database it runs very quick, it just runs slow on remote databases

  Hi does anyone know what the xsl would look like to transform this XML. There can be N nte's after pid and N nte's after pv1. The structure is guaranteed in that all nte that follows pid belongs to pid and all nte following pv1 belongs to pv1. From: <pid> </pid> <nte> <nte-1>1</nte-1> <nte-3>Note 1</nte-1> </nte> <nte></nte> <pv1></pv1> <nte> </nte> into: <pid> <nte> <nte-1>1</nte-1> <nte-3>Note 1</nte-1> </nte> <nte> </nte> </pid> <pv1> <nte> </nte> </pv1> Thanks!

• EDIT: I need to generate a string of 7 chars that is based on the id of the row.

  - by Totty

  EDIT: I need to generate a string of 7 chars that is based on the id of the row. So knowing the id of the image and a secret key, i should get the generated string. the string must contain chars from "a" to "z" and numbers from 0 to 9. I have a dir that contains photos like this dir/p3/i2/s21/thumb.jpg the generated string is p3i2s21, then is used to calculate the path of the image. EDIT: currently im using the id of the image: id = 55 then i modify and i get path = 000000055 then path = "000/000/055" then path = "000/000/055/thumb.jpg" ready to use! now i want something more clever because is easy to track down all the images from a server, because ids are sequencial: 1, 2, 3, 4, 5, 6... so i must think of creating from 55 a string that is 7 char length and will not overlap with other numbers. I can even transform the 55 to 0000055 and from this convert to a 7 char length string using a secret string. then when i got the secret string and the id i want to get back that 7 char length string. Is this possible? i was thinking about hases but they only uses 0-9 and a-e and are more chars.. :s

• Having trouble Getting "RTSP over HTTP"

  - by Muhammad Adeel Zahid

  There is an axis camera that is connected to our site (camba.tv) through axis one click connection component (which acts as proxy). We can communicate with this camera only through http by setting the proxy to our OCCC server's address. If we want to get RTSP streams (h.264) we are only left with "RTSP over HTTP" option. For this I have followed axis VAPIX 3 documentation section 3.3. I issue requests through fiddler but don't get any response. But when i put the URL (axrtsphttp://1.00408CBEA38B/axis-media/media.amp) in windows media player (with proxy set to OCCC server 212.78.237.156:3128) the player is able to get RTSP stream over HTTP after logging in. I have created a request trace of communication between camera and windows media player through wireshark and the request that brings the stream looks like http://1.00408cbea38b/axis-media/media.amp HTTP/1.1 x-sessioncookie: 619 User-Agent: Axis AMC Host: 1.00408CBEA38B Proxy-Connection: Keep-Alive Pragma: no-cache Authorization: Digest username="root",realm="AXIS_00408CBEA38B",nonce="000a8b40Y0100409c13ac7e6cceb069289041d8feb1691",uri="/axis-media/media.amp",cnonce="9946e2582bd590418c9b70e1b17956c7",nc=00000001,response="f3cab86fc84bfe33719675848e7fdc0a",qop="auth" HTTP/1.0 200 OK Content-Type: application/x-rtsp-tunnelled Date: Tue, 02 Nov 2010 11:45:23 GMT RTSP/1.0 200 OK CSeq: 1 Content-Type: application/sdp Content-Base: rtsp://1.00408CBEA38B/axis-media/media.amp/ Date: Tue, 02 Nov 2010 11:45:23 GMT Content-Length: 410 v=0 o=- 1288698323798001 1288698323798001 IN IP4 1.00408CBEA38B s=Media Presentation e=NONE c=IN IP4 0.0.0.0 b=AS:50000 t=0 0 a=control:* a=range:npt=0.000000- m=video 0 RTP/AVP 96 b=AS:50000 a=framerate:30.0 a=transform:1,0,0;0,1,0;0,0,1 a=control:trackID=1 a=rtpmap:96 H264/90000 a=fmtp:96 packetization-mode=1; profile-level-id=420029; sprop-parameter-sets=Z0IAKeNQFAe2AtwEBAaQeJEV,aM48gA== RTSP/1.0 200 OK CSeq: 2 Session: 3F4763D8; timeout=60 Transport: RTP/AVP/TCP;unicast;interleaved=0-1;ssrc=060922C6;mode="PLAY" Date: Tue, 02 Nov 2010 11:45:24 GMT RTSP/1.0 200 OK CSeq: 3 Session: 3F4763D8 Range: npt=0- RTP-Info: url=rtsp://1.00408CBEA38B/axis-media/media.amp/trackID=1;seq=7392;rtptime=4190934902 Date: Tue, 02 Nov 2010 11:45:24 GMT [Binary Stream Content] But when i copy this request to fiddler, I only get 200 status code with content-type set to application/x-rtsp-tunneled and there is no stream data. The only thing i do different with stream is to use Basic in authorization header instead of Digest and I do not get 401 (Un authorized) status code. Can anyone explain what's happening here? How can I write request sequences to get stream in fiddler? If it is needed, I can upload the wireshark request dump somewhere.

• Looking for app to work fluidly with CSV data in graph form

  - by Aszurom

  It often occurs to me that if I had a good tool for viewing CSV data in graphical format, and comparing two sets of numbers to each other, I could do a great deal of meaningful trend watching and data interpretation. For example, perfmon can output quite a lot of data about a server into a CSV file, but there's no good way to view it. A lot of scripts could/have been written that would populate CSV files. I could write these all day long. My problem is that I need a great viewer. I've seen quite a few things that will take a CSV file and after a lot of tweaking and user adjustment produce a static gif/png image. A static image doesn't do me a lot of good, because I have to look at it, then re-calibrate the parameters of the program, regenerate the image, repeat. That sucks. I could do this in Excel. Ideally, I would want a FLUID graph viewer. On the fly, I can adjust how much of my timeline I'm viewing. I could adjust the scaling so that one big spike doesn't make 99.9% of the data an unreadable line across the bottom of the X axis. Stuff like that. I should be able to say "show me CSV column 3 and column 5 as graphs. Show me the data scaled for 20 or 150 entries, and let me slide that window up and down the column of data. Auto scale to fit 95% of data within the Y axis and let crazy spikes go off the screen." Maybe I'm terribly spoiled by how you can drag, zoom, and slide data around on my iPad. I want to be able to view a spreadsheet of data with that fluidity and not have to guess at what sort of static snapshot I want to create from it. I don't want to have to make a study of how to tweak some data plotting program to let me import my file and do what I could just do in Excel. I want to scale, zoom, and transform my graph on the fly and then export a snapshot of it once I have it the way I want it. Is there anything out there that fills this need? I'll take linux, osx, win32 or even iOS suggestions.

• How to configure apache's mod_proxy_html to work as an ajax proxy?

  - by dcerecedo

  I'm trying to build a web site that let's you view and manipulate data from any page in any other website. To do that, I have to bypass 'Allow Origin' problems: i'm loading the other domain's content in an iframe and i have to manipulate its content with javascript downloaded from my domain. My first attempt was to write a simple proxy myself, requesting the other domains page through a server proxy coded in Java that not only serves the content but rebuilds links (src's and href's) in the content so that the content referenced by these links alse get downloaded through my handmade proxy. The result is not bad but has problems with url's in css and scripts. It's then that i realized that mod_proxy_html is supposed to do exactly all this job. The problem is that i cannot figure out how to make it work as expected. Let's suppose my server runs in my-domain.com and to proxy and transform content from another domain i'd make a request like this: my-domain.com/proxy?url=http://another-domain.com/some/content I'd want mod_proxy_html to serve the content and rewrite following URLs in http://another-domain.com/some/content in the following ways: Absolute URLs not from another-domain.com: no rewritting Relative from root urls:/other/content - /proxy?url=http://another-domain.com/other/content Relative urls: other/content - /proxy?url=http://another-domain.com/some/content/other/content Relative to parent urls: ../other/content - /proxy?url=http://another-domain.com/some/other/content The url should be specified at runtime, not configuration time. Can this be achieved with mod_proxy_html? Could anyone provide a simple working configuration to start with? EDIT 1-First approach The following site config will work fine with sites that use absolute url's everywhere like http://www.huffingtonpost.es/. Youc could try on this config on localhost: http://localhost/asset/http://www.huffingtonpost.es/ <VirtualHost *:80> ServerName localhost LogLevel debug ProxyRequests off RewriteEngine On RewriteRule ^/asset/(.*) $1 [P] ProxyHTMLURLMap $1 /asset/ <Location /asset/> ProxyPassReverse / ProxyHTMLURLMap / /asset/ </Location> </VirtualHost> But as explained in the documentation, if I hit a site using relative url's, I'd like to have these rewritten on the html via mod_proxy_html. So I shoud change the Location block as follows: <Location /asset/> ProxyPassReverse / #Depending on your system use one line or the other #Ubuntu: #SetOutputFilter proxy-html #any other system: ProxyHTMLEnable On ProxyHTMLURLMap / /asset/ </Location> ...which doesn't seem to work. Comments, hints and ideas welcome!

• Trace File Source Adapter

  The Trace File Source adapter is a useful addition to your SSIS toolbox.  It allows you to read 2005 and 2008 profiler traces stored as .trc files and read them into the Data Flow.  From there you can perform filtering and analysis using the power of SSIS. There is no need for a SQL Server connection this just uses the trace file. Example Usages Cache warming for SQL Server Analysis Services Reading the flight recorder Find out the longest running queries on a server Analyze statements for CPU, memory by user or some other criteria you choose Properties The Trace File Source adapter has two properties, both of which combine to control the source trace file that is read at runtime. SQL Server 2005 and SQL Server 2008 trace files are supported for both the Database Engine (SQL Server) and Analysis Services. The properties are managed by the Editor form or can be set directly from the Properties Grid in Visual Studio. Property Type Description AccessMode Enumeration This property determines how the Filename property is interpreted. The values available are: DirectInput Variable Filename String This property holds the path for trace file to load (*.trc). The value is either a full path, or the name of a variable which contains the full path to the trace file, depending on the AccessMode property. Trace Column Definition Hopefully the majority of you can skip this section entirely, but if you encounter some problems processing a trace file this may explain it and allow you to fix the problem. The component is built upon the trace management API provided by Microsoft. Unfortunately API methods that expose the schema of a trace file have known issues and are unreliable, put simply the data often differs from what was specified. To overcome these limitations the component uses  some simple XML files. These files enable the trace column data types and sizing attributes to be overridden. For example SQL Server Profiler or TMO generated structures define EventClass as an integer, but the real value is a string. TraceDataColumnsSQL.xml  - SQL Server Database Engine Trace Columns TraceDataColumnsAS.xml    - SQL Server Analysis Services Trace Columns The files can be found in the %ProgramFiles%\Microsoft SQL Server\100\DTS\PipelineComponents folder, e.g. "C:\Program Files\Microsoft SQL Server\100\DTS\PipelineComponents\TraceDataColumnsSQL.xml" "C:\Program Files\Microsoft SQL Server\100\DTS\PipelineComponents\TraceDataColumnsAS.xml" If at runtime the component encounters a type conversion or sizing error it is most likely due to a discrepancy between the column definition as reported by the API and the actual value encountered. Whilst most common issues have already been fixed through these files we have implemented specific exception traps to direct you to the files to enable you to fix any further issues due to different usage or data scenarios that we have not tested. An example error that you can fix through these files is shown below. Buffer exception writing value to column 'Column Name'. The string value is 999 characters in length, the column is only 111. Columns can be overridden by the TraceDataColumns XML files in "C:\Program Files\Microsoft SQL Server\100\DTS\PipelineComponents\TraceDataColumnsAS.xml". Installation The component is provided as an MSI file which you can download and run to install it. This simply places the files on disk in the correct locations and also installs the assemblies in the Global Assembly Cache as per Microsoft’s recommendations. You may need to restart the SQL Server Integration Services service, as this caches information about what components are installed, as well as restarting any open instances of Business Intelligence Development Studio (BIDS) / Visual Studio that you may be using to build your SSIS packages. Finally you will have to add the transformation to the Visual Studio toolbox manually. Right-click the toolbox, and select Choose Items.... Select the SSIS Data Flow Items tab, and then check the Trace File Source transformation in the Choose Toolbox Items window. This process has been described in detail in the related FAQ entry for How do I install a task or transform component? We recommend you follow best practice and apply the current Microsoft SQL Server Service pack to your SQL Server servers and workstations. Please note that the Microsoft Trace classes used in the component are not supported on 64-bit platforms. To use the Trace File Source on a 64-bit host you need to ensure you have the 32-bit (x86) tools available, and the way you execute your package is setup to use them, please see the help topic 64-bit Considerations for Integration Services for more details. Downloads Trace Sources for SQL Server 2005 -- Trace Sources for SQL Server 2008 Version History SQL Server 2008 Version 2.0.0.382 - SQL Sever 2008 public release.

• Book Review Charlene Li's New Book: Open Leadership

  - by david.talamelli

  A few weeks ago, I was surprised when I looked in our mail box. I had received an Advance Copy of Charlene Li's new book titled "Open Leadership: How Social Technology Can Transform the Way You Lead". Charlene sent a tweet a while back asking anyone interested in receiving the book to submit their details. I sent off my details and didn't think I would hear anything back, so it was a pleasant surprise. With that I almost feel bad that it has taken me 3 weeks to read her book. It took this long mainly because it has been hard to fit in some quality reading time for myself with work, the kids, volunteering, etc..... I am happy to report I have finished her book and wanted to run through my initial thoughts with you. I first came across Charlene Li after reading her book "Groundswell" a few years ago, her latest book "Open Leadership" is a follow on from Groundswell and to me it seems like a natural progression from the question "Ok the business landscape is changing, what do we do now?" For me these two books have a different writing style to them. Groundswell from memory spoke about broad social media concepts and adoption and alerted us to some of the changes taking place in the SM landscape. Open Leadership seems to be focussed on taking those broad concepts and finding ways to implement them into your environment. That is breaking broad concepts down into individual action items that can be measured and analysed. As the business world changes Leaders must change their approach and let go of control to more control. One of the things I love reading about is seeing real life examples of how people and organisations are making these things happen. In this book Charlene has collected some great collateral and case studies from companies such as Cisco, Best Buy, The Red Cross and The State Bank of India (as a side-note, I wish now that I submitted my input for the Leaders I work with here at Oracle - there are some great examples here of people who empower their staff). As society becomes more adept at using social media it is inevitable that Leaders must become open with their employees, clients and partners. From the book some of the key points I took away are (I actually took away a lot more from this book, this is just an overview) : 1) Organisations should encourage risk taking. Without being a "hacker", how can we improve ourselves, our processes, our business, etc... The old saying you only fail by not trying applies here. If Leaders create a culture where people are afraid to stick their neck out - how will you innovate? 2) Leaders need to lead by example - if you want to promote an open and transparent business, a Leader needs to exemplify the traits they would like to see out of their employees. 3) The definition of a Leader is changing, open leadership is about being a catalyst to change that uses networks to spread a vision as opposed to traditional leadership that is viewed as a role. 4) There is a cultural and business shift taking place. Information is more wide-spread and is being disseminated faster than any other time in the past. Leaders who are open and transparent will thrive in this new business environment. 5) Leadership is not defined by a title - it is defined by a person's actions. Also anyone can be a Leader or has Leadership potential in them- it is a matter of drawing that out of people. I found this book useful and I also found myself looking at my own actions and the actions of others around me (including my management) to see how open and transparent I am in my work. For me I am glad I read this book as it validated my own thoughts of the changes we are seeing take place. This book has certainly given me some new ideas and helped me push my own boundaries of what I can do. The book has a number of action plans at the end of some of the chapters such as "Conducting you Openness Audit" that I think have helped me take thoughts and ideas and turn them into concrete action items. I have included a link to the introduction of the book here if anyone wants to have a read of it. If anyone else has read this book, it would be great to hear your thoughts/comments/review. Leave your comments below. This article was originally posted on David Talamelli's Blog - David's Journal on Tap

• How to customise search core results web part Part1

  - by ybbest

  In this post, I’d like to show you how to customise search core results web part. It is a quite simple, most of the times what you need to do is to change the xslt to perform the changes. Here are the steps: 1. You need to change the xslt to the following, so that you can see the raw xml. <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" > <xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes" /> <xsl:template match="/"> <xmp><xsl:copy-of select="*"/></xmp> </xsl:template> </xsl:stylesheet> a. To do so , you need to go to edit page>>Edit search core results web part >>Display Properties and then untick use Location Visualization b. Open the xslt editor and copy the existing XSLT code to your preferred xslt editor so that you can customise it. c. Now you can paste in the XSLT code above. 2.Perform the search after you have completed step1 and you will see the search results returned in raw xml <All_Results> <Result> <id>1</id> <workid>678</workid> <rank>100000000</rank> <title>Ybbest</title> <author></author> <size>137531</size> <url>http://ybbest</url> <urlEncoded>http%3A%2F%2Fybbest</urlEncoded> <description>Ybbest test site</description> <write>3/17/2012</write> <sitename>http://ybbest</sitename> <collapsingstatus>0</collapsingstatus> <hithighlightedsummary> <c0>Ybbest</c0> test site <ddd /> Add a new image, change this welcome text or add new lists to this page by clicking the edit button above. You can click on Shared Documents to add files or on the <ddd /> </hithighlightedsummary> <hithighlightedproperties> <HHTitle> <c0>Ybbest</c0> </HHTitle> <HHUrl>http://<c0>ybbest</c0></HHUrl> </hithighlightedproperties> <contentclass>STS_Site</contentclass> <isdocument>False</isdocument> <picturethumbnailurl></picturethumbnailurl> <popularsocialtags /> <picturewidth>0</picturewidth> <pictureheight>0</pictureheight> <datepicturetaken></datepicturetaken> <serverredirectedurl></serverredirectedurl> <fileextension></fileextension> <ows_metadatafacetinfo></ows_metadatafacetinfo> <imageurl imageurldescription="SharePoint Site Collection">/_layouts/images/siteicon_16x16.png</imageurl> </Result> <TotalResults>69</TotalResults> <NumberOfResults>50</NumberOfResults> </All_Results> 3. Then you can read what has been returned in the raw xml and start modifying the xslt to customise your search results page. 4.You can also link an external xslt to the web part.It can be set in the Miscellaneous of Web Part section. You can also set it pragmatically using a feature receiver , you can download the source code to do so here.

• Building the Elusive Windows Phone Panorama Control

  When the Windows Phone 7 Developer SDK was released a couple of weeks ago at MIX10 many people noticed the SDK doesnt include a template for a Panorama control.   Here at Clarity we decided to build our own Panorama control for use in some of our prototypes and I figured I would share what we came up with. There have been a couple of implementations of the Panorama control making their way through the interwebs, but I didnt think any of them really nailed the experience that is shown in the simulation videos.   One of the key design principals in the UX Guide for Windows Phone 7 is the use of motion.  The WP7 OS is fairly stripped of extraneous design elements and makes heavy use of typography and motion to give users the necessary visual cues.  Subtle animations and wide layouts help give the user a sense of fluidity and consistency across the phone experience.  When building the panorama control I was fairly meticulous in recreating the motion as shown in the videos.  The effect that is shown in the application hubs of the phone is known as a Parallax Scrolling effect.  This this pseudo-3D technique has been around in the computer graphics world for quite some time. In essence, the background images move slower than foreground images, creating an illusion of depth in 2D.  Here is an example of the traditional use: http://www.mauriciostudio.com/.  One of the animation gems I've learned while building interactive software is the follow animation.  The premise is straightforward: instead of translating content 1:1 with the interaction point, let the content catch up to the mouse or finger.  The difference is subtle, but the impact on the smoothness of the interaction is huge.  That said, it became the foundation of how I achieved the effect shown below.   Source Code Available HERE Before I briefly describe the approach I took in creating this control..and Ill add some **asterisks ** to the code below as my coding skills arent up to snuff with the rest of my colleagues.  This code is meant to be an interpretation of the WP7 panorama control and is not intended to be used in a production application.  1.  Layout the XAML The UI consists of three main components :  The background image, the Title, and the Content.  You can imagine each  these UI Elements existing on their own plane with a corresponding Translate Transform to create the Parallax effect.  2.  Storyboards + Procedural Animations = Sexy As I mentioned above, creating a fluid experience was at the top of my priorities while building this control.  To recreate the smooth scroll effect shown in the video we need to add some place holder storyboards that we can manipulate in code to simulate the inertia and snapping.  Using the easing functions built into Silverlight helps create a very pleasant interaction.    3.  Handle the Manipulation Events With Silverlight 3 we have some new touch event handlers.  The new Manipulation events makes handling the interactivity pretty straight forward.  There are two event handlers that need to be hooked up to enable the dragging and motion effects: the ManipulationDelta event :  (the most relevant code is highlighted in pink) Here we are doing some simple math with the Manipulation Deltas and setting the TO values of the animations appropriately. Modifying the storyboards dynamically in code helps to create a natural feel.something that cant easily be done with storyboards alone.   And secondly, the ManipulationCompleted event:  Here we take the Final Velocities from the Manipulation Completed Event and apply them to the Storyboards to create the snapping and scrolling effects.  Most of this code is determining what the next position of the viewport will be.  The interesting part (shown in pink) is determining the duration of the animation based on the calculated velocity of the flick gesture.  By using velocity as a variable in determining the duration of the animation we can produce a slow animation for a soft flick and a fast animation for a strong flick. Challenges to the Reader There are a couple of things I didnt have time to implement into this control.  And I would love to see other WPF/Silverlight approaches.  1.  A good mechanism for deciphering when the user is manipulating the content within the panorama control and the panorama itself.   In other words, being able to accurately determine what is a flick and what is click. 2.  Dynamically Sizing the panorama control based on the width of its content.  Right now each control panel is 400px, ideally the Panel items would be measured and then panorama control would update its size accordingly.  3.  Background and content wrapping.  The WP7 UX guidelines specify that the content and background should wrap at the end of the list.  In my code I restrict the drag at the ends of the list (like the iPhone).  It would be interesting to see how this would effect the scroll experience.     Well, Its been fun building this control and if you use it Id love to know what you think.  You can download the Source HERE or from the Expression Gallery  Erik Klimczak  | [email protected] | twitter.com/eklimczDid you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• Internet Explorer and Cookie Domains

  - by Rick Strahl

  I've been bitten by some nasty issues today in regards to using a domain cookie as part of my FormsAuthentication operations. In the app I'm currently working on we need to have single sign-on that spans multiple sub-domains (www.domain.com, store.domain.com, mail.domain.com etc.). That's what a domain cookie is meant for - when you set the cookie with a Domain value of the base domain the cookie stays valid for all sub-domains. I've been testing the app for quite a while and everything is working great. Finally I get around to checking the app with Internet Explorer and I start discovering some problems - specifically on my local machine using localhost. It appears that Internet Explorer (all versions) doesn't allow you to specify a domain of localhost, a local IP address or machine name. When you do, Internet Explorer simply ignores the cookie. In my last post I talked about some generic code I created to basically parse out the base domain from the current URL so a domain cookie would automatically used using this code:private void IssueAuthTicket(UserState userState, bool rememberMe) { FormsAuthenticationTicket ticket = new FormsAuthenticationTicket(1, userState.UserId, DateTime.Now, DateTime.Now.AddDays(10), rememberMe, userState.ToString()); string ticketString = FormsAuthentication.Encrypt(ticket); HttpCookie cookie = new HttpCookie(FormsAuthentication.FormsCookieName, ticketString); cookie.HttpOnly = true; if (rememberMe) cookie.Expires = DateTime.Now.AddDays(10); var domain = Request.Url.GetBaseDomain(); if (domain != Request.Url.DnsSafeHost) cookie.Domain = domain; HttpContext.Response.Cookies.Add(cookie); } This code works fine on all browsers but Internet Explorer both locally and on full domains. And it also works fine for Internet Explorer with actual 'real' domains. However, this code fails silently for IE when the domain is localhost or any other local address. In that case Internet Explorer simply refuses to accept the cookie and fails to log in. Argh! The end result is that the solution above trying to automatically parse the base domain won't work as local addresses end up failing. Configuration Setting Given this screwed up state of affairs, the best solution to handle this is a configuration setting. Forms Authentication actually has a domain key that can be set for FormsAuthentication so that's natural choice for the storing the domain name: <authentication mode="Forms"> <forms loginUrl="~/Account/Login" name="gnc" domain="mydomain.com" slidingExpiration="true" timeout="30" xdt:Transform="Replace"/> </authentication> Although I'm not actually letting FormsAuth set my cookie directly I can still access the domain name from the static FormsAuthentication.CookieDomain property, by changing the domain assignment code to:if (!string.IsNullOrEmpty(FormsAuthentication.CookieDomain)) cookie.Domain = FormsAuthentication.CookieDomain; The key is to only set the domain when actually running on a full authority, and leaving the domain key blank on the local machine to avoid the local address debacle. Note if you want to see this fail with IE, set the domain to domain="localhost" and watch in Fiddler what happens. Logging Out When specifying a domain key for a login it's also vitally important that that same domain key is used when logging out. Forms Authentication will do this automatically for you when the domain is set and you use FormsAuthentication.SignOut(). If you use an explicit Cookie to manage your logins or other persistant value, make sure that when you log out you also specify the domain. IOW, the expiring cookie you set for a 'logout' should match the same settings - name, path, domain - as the cookie you used to set the value.HttpCookie cookie = new HttpCookie("gne", ""); cookie.Expires = DateTime.Now.AddDays(-5); // make sure we use the same logic to release cookie var domain = Request.Url.GetBaseDomain(); if (domain != Request.Url.DnsSafeHost) cookie.Domain = domain; HttpContext.Response.Cookies.Add(cookie); I managed to get my code to do what I needed it to, but man I'm getting so sick and tired of fixing IE only bugs. I spent most of the day today fixing a number of small IE layout bugs along with this issue which took a bit of time to trace down.© Rick Strahl, West Wind Technologies, 2005-2012Posted in ASP.NET   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); })();

• &ldquo;My life at Oracle&rdquo;

  - by cristian.condurache(at)oracle.com

  Hello everybody! My name is Eva and I currently work in Oracle Italy as Sales Programs Manager for the Technology Sales organization. Since 2009, I also proudly represent the Oracle Education Foundation within my country as the Ambassador for Italy. My career path in this amazing company began 5 years ago as a fresh graduate: after various years studying abroad, in Germany and Ireland mainly, I was looking for a valuable and concrete opportunity which could fulfill my energetic spirit. I wanted to develop myself inside a stimulating and “fast” business environment.. and here came Oracle and I really couldn’t ask for anything better!  THE PARTNER EXPERIENCE The first department I had the chance to work into was the Alliances and Channels organization, where I had the opportunity to join a brilliant team of great and visionary guys. I began having the responsibility to analyze and rationalize the portfolio of Oracle business partners and to identify potential cross-area solutions, which had to be highlighted both on the local market and internationally: this ended up with the implementation of the “Partner Community” model, a business environment of selected Oracle partners, specialized on the different technology focus areas. This new concept was then recognized as an EMEA Best Practice and replicated internationally. Having the opportunity to strengthen day after day strategic relationships with several business partners and study the market positioning of their technology solutions, I was given the role to develop the “Oracle Partner Network Innovation Award” in Italy: the EMEA competition encouraging and rewarding proven and successful technology innovations, creating high value for our common customers and generating new business potential. Several Italian partner solutions won different prizes and I decided that it was worth collecting all those valuable projects, winners and short-listed, inside two specific books in order also to provide them an international market visibility: OPN Innovation Award Booklet 2007 and OPN Innovation Award Booklet 2008 Inside the Alliances and Channels department I really had the opportunity to do    amazing things, like for example working side-by-side with one of the most exceptional teams in Oracle I have ever worked with: the EMEA Recruitment Team. Together, in fact, we conceived a brand new business initiative for our partners, called “Oracle Campus Joint Program”. This program was awarded as an EMEA Best Practice and acknowledged by both Italian public institutions and press media. Italy   is currently running its 5th edition.   Briefly, the “Oracle Campus Joint Program” aims at facing the growing issue of lack of  technology competences and skills on the market. By identifying a specific technology area and developing an intensive 4-6 week Oracle University training course and by collaborating with important academic institutes, international “gurus” and professionals, our business partners are able to benefit from a pool of brilliant top talented young consultants and offer them a significant career opportunity. BUSINESS BUT NOT ONLY: THE NO-PROFIT EXPERIENCE OF ORACLE Currently my mission in Oracle is to continue driving the implementation of strategic business development and sales programs for the entire Oracle Technology stack, involving both partners and the end-customers. But as a completely distinguished role from the day-today business, I’m also honored to represent in Italy the charity global organization founded by Oracle - the Oracle Education Foundation - and drive its corporate citizenship and marketing programs. Oracle Education Foundation is an independent charitable organization funded by Oracle and is dedicated to helping students develop 21st century skills through project learning and the use of technology. It provides “ThinkQuest” as a free program to primary and secondary (K12) schools. Just some significant numbers: today 548,000 students/teachers in 47 countries use ThinkQuest and the Oracle Education Foundation partners with 40+ no-profit or government organizations globally. ABOUT MYSELF AND MY INTERESTS About myself…I’m very enthusiastic and positive, trying always to transform difficult issues in challenging opportunities. My day usually begins very early in the morning with running, swimming or when I need to collect some “zen” energies with a yoga session or better with a long walk with my dog. I definitely love animals and generally speaking I’m very keen on environmental issues and try, as much as I can, to carry out a healthy and “planet respectful” lifestyle. My thirst for knowledge pushed me some time ago to begin a new personal challenge: I decided to enroll, dedicating a good part of my free time, for a second university degree: I chose “Neuroeconomics”, an innovative academic path which combines psychology, economics, and neuroscience and studies how people make decisions and the role of the brain when people evaluate these decisions, categorizing risks and rewards and generally interacting with each other. I’ve been very glad to talk about my experience in this article, as working for Oracle is something very stimulating. This company ensures you the opportunity to face new challenges, work with highly talented people and be professionally highlighted also globally. Motivation, good results and innovation is always pursued, recognized and fully supported. Thanks and wish you all an amazing career! If you have any question please contact [email protected].

• Replication Services in a BI environment

  - by jorg

  In this blog post I will explain the principles of SQL Server Replication Services without too much detail and I will take a look on the BI capabilities that Replication Services could offer in my opinion. SQL Server Replication Services provides tools to copy and distribute database objects from one database system to another and maintain consistency afterwards. These tools basically copy or synchronize data with little or no transformations, they do not offer capabilities to transform data or apply business rules, like ETL tools do. The only “transformations” Replication Services offers is to filter records or columns out of your data set. You can achieve this by selecting the desired columns of a table and/or by using WHERE statements like this: SELECT <published_columns> FROM [Table] WHERE [DateTime] >= getdate() - 60 There are three types of replication: Transactional Replication This type replicates data on a transactional level. The Log Reader Agent reads directly on the transaction log of the source database (Publisher) and clones the transactions to the Distribution Database (Distributor), this database acts as a queue for the destination database (Subscriber). Next, the Distribution Agent moves the cloned transactions that are stored in the Distribution Database to the Subscriber. The Distribution Agent can either run at scheduled intervals or continuously which offers near real-time replication of data! So for example when a user executes an UPDATE statement on one or multiple records in the publisher database, this transaction (not the data itself) is copied to the distribution database and is then also executed on the subscriber. When the Distribution Agent is set to run continuously this process runs all the time and transactions on the publisher are replicated in small batches (near real-time), when it runs on scheduled intervals it executes larger batches of transactions, but the idea is the same. Snapshot Replication This type of replication makes an initial copy of database objects that need to be replicated, this includes the schemas and the data itself. All types of replication must start with a snapshot of the database objects from the Publisher to initialize the Subscriber. Transactional replication need an initial snapshot of the replicated publisher tables/objects to run its cloned transactions on and maintain consistency. The Snapshot Agent copies the schemas of the tables that will be replicated to files that will be stored in the Snapshot Folder which is a normal folder on the file system. When all the schemas are ready, the data itself will be copied from the Publisher to the snapshot folder. The snapshot is generated as a set of bulk copy program (BCP) files. Next, the Distribution Agent moves the snapshot to the Subscriber, if necessary it applies schema changes first and copies the data itself afterwards. The application of schema changes to the Subscriber is a nice feature, when you change the schema of the Publisher with, for example, an ALTER TABLE statement, that change is propagated by default to the Subscriber(s). Merge Replication Merge replication is typically used in server-to-client environments, for example when subscribers need to receive data, make changes offline, and later synchronize changes with the Publisher and other Subscribers, like with mobile devices that need to synchronize one in a while. Because I don’t really see BI capabilities here, I will not explain this type of replication any further. Replication Services in a BI environment Transactional Replication can be very useful in BI environments. In my opinion you never want to see users to run custom (SSRS) reports or PowerPivot solutions directly on your production database, it can slow down the system and can cause deadlocks in the database which can cause errors. Transactional Replication can offer a read-only, near real-time database for reporting purposes with minimal overhead on the source system. Snapshot Replication can also be useful in BI environments, if you don’t need a near real-time copy of the database, you can choose to use this form of replication. Next to an alternative for Transactional Replication it can be used to stage data so it can be transformed and moved into the data warehousing environment afterwards. In many solutions I have seen developers create multiple SSIS packages that simply copies data from one or more source systems to a staging database that figures as source for the ETL process. The creation of these packages takes a lot of (boring) time, while Replication Services can do the same in minutes. It is possible to filter out columns and/or records and it can even apply schema changes automatically so I think it offers enough features here. I don’t know how the performance will be and if it really works as good for this purpose as I expect, but I want to try this out soon!
