  • My Portable Hard Drive with USB3 didn't work when connected to My Laptop, but it working with USB2 properly

    - by Mohammad Hasan Esfahanian
    I have Western Digital My Passport Essential Portable Hard Drive with USB3 and Model:WDBACY5000ABK-EESN. Until about two or three months ago when I connected that to My Laptop USB3 port, that worked very well. But now when I'm connecting that to My device, The system does not detect any Hard Drives. When plug in the USB2 port is working properly. I connected that to another Laptop whit USB3 port but I had the same problem. I tested My Laptop port with a Flash Memory by USB3 and ports were healthy and I'm sure they are working. For this issue, I changed the windows, but it still did not work. What can I do? Thanks in advance.

  • Making your own shortcuts on Windows

    - by Mohammad
    Hello all, I'm using Windows Vista, and I was wondering if I can put shortcuts for applications.Like for example, if I press a certain combination of keys I get notepad, or something like that. If those shortcuts were already there, how can I know them? Another thing, if I have an application that runs on media files for example, can I add it on the " Right Click" menu when I right click on media files. I hope you got that :) Thanks alot :)

  • DataSet does not support System.Nullable<>

    - by a_m0d
    I'm trying to set the DataSource for a Crystal Reports report, but I've run into a few problems. I've been following a guide written by Mohammad Mahdi Ramezanpour, and have managed to get all the way to the last part now (setting the DataSource). However, I have a problem that Mohammad does not seem to have - when I pass the results of my query to the report, I end up with the following exception: DataSet does not support System.Nullable< This is the query I am using: public IQueryable<Part> GetPartsToDisplayOnStockReport() { return from part in db.Parts where part.showOnStockReport == true select part; } and the way I pass it to the Report: public ActionResult ViewStockReport() { StockReport stockReport = new StockReport(); var parts = ordersRepository.GetPartsToDisplayOnStockReport().ToList(); stockReport.SetDataSource(parts); Stream stream = stockReport.ExportToStream(CrystalDecisions.Shared.ExportFormatType.PortableDocFormat); return File(stream, "application/pdf"); } I have also tried changing my query to this code, in the hope that it would fix my problem: return (from part in db.Parts where part.showOnStockReport == true select part) ?? db.Parts.DefaultIfEmpty(); but it still complained about the same problem. How can I pass the results of this query to my report, to use it as a data source? Also, if each of my Parts object contains other objects / collections of other objects, will I be able to reference them in the report with a datasource like this?

  • 2014 Conferences - JFokus, JavaLand & GeeCon!

    - by Heather VanCura
    There has been a delay in publishing these past event summaries from early 2014--JFokus in February, JavaLand in March, and GeeCon in May. As we plan for Devoxx UK next week, I found these summaries that did not make it past 'draft' stage.  We had some great successes with the first three events of 2014, a Java developer conference trifecta! Participation topics included Java, the JCP program overall and the Adopt-a-JSR programs.   First up in February was JFokus in Stockholm. The energy and talent in Stockholm is amazing and the conference organizers do a stellar job running it and welcoming the speakers of this event.  I enjoyed the city walk and speaker dinner, as well as many opportunities to interact with conference speakers and attendees, both during and after the conference hours. Reza Rehman invited me to speak during his Java EE 7 lab session about the Adopt-a-JSR program, and I gave a quickie session on the JCP and Adopt-a-JSR.  There was also a late night Birds of a Feather (BoF) session held jointly with Cecelia Borg, Martijn Verburg and Reza Rehman.  This was an interactive conversation with a focus on the Java EE community survey results and encouraging more community participation and collaboration in Java development.  The Java 8 keynote by Georges Saab and Mark Reinhold was also very entertaining,  I was sorry to miss FOSDEM happening the previous weekend this year in Brussels, but I hope to attend in 2015.  Favorite take home gift -- Lambdas cap! In March, the inaugural version of the JavaLand conference happened inside Phantasialand, an amusement park in Germany. Markus Eisele suggested having an Early Adopters area at the conference, which I was keen to implement. In 2013 at Devoxx Belgium we held some activities in the Hackergaren area around Lambdas and Java EE 7, so this was a great opportunity to expand on a more interactive conference format and Andreas Badelt from the program committee helped in the planning for this area.  Daniel Bryant and Mani Sarkar from the London Java Community led some general Adopt-a-JSR discussions and AdoptOpen JDK activities.  JCP Spec Leads, Anatole Tresch from Credit Suisse, leading JSR 354, Money & Currency API, and Ed Burns from Oracle, leading JSR 344, JavaServer Faces 2.2, attended to engage with conference attendees on their JSRs.  Favorite - Stephen Chin's roller coaster video. In May, GeeCon in Krakow was anther awesome conference!  The conference organizers were warm and welcoming and I enjoyed time getting to know the other speakers at the event. There was a JCP and Adopt-a-JSR participation session as well as a moderated panel session on Early Adopters.  We had an amazing panel -- Daniel Bryant, Arun Gupta, Tomasz Borek , and Peter Lawrey. The panel discussed the Adopt-a-JSR and Adopt OpenJDK program, and how the participants work together to get involved and contribute to both the Java SE and Java EE platforms.  If was an interesting discussion and sparked some new ideas on how Java User Groups in Poland and around the world can contribute in a significant and meaningful way to create better and more practical Java standards today and in the future.  Favorite take home gift - GeeCon mug!   These were some of the highlights of the events--looking forward to Devoxx UK next week.  I will publish these details tomorrow!

  • How to make php closure compiler write to a predefined file name?

    - by Mohammad
    I'm quite embarrassed to ask this but I've been trying to figure it out all day with no luck. http://code.google.com/p/php-closure/source/browse/trunk/php-closure.php on Line 172 the write() function get the md5 encoded name via the _getHash() function on Line 276. I was wondering how I could alter this code to write the compiled code to a predefined name like copiled_code.js I've tried altering the _getCacheFileName() function on Line 272 to this function _getCacheFileName() { //return $this->_cache_dir . $this->_getHash() . ".js"; return 'copiled_code.js'; } without any results. Thanks to all of you in advance!

  • How to implement JQuery easing into this window scroll movement function?

    - by Mohammad
    With this code I've been able to capture the mousewheel movement and apply it to the horizontal scroll bars instead of the vertical default. $('html').bind('mousewheel', function(event, delta) { window.parent.scrollBy(-120 * delta, 0); return false; }); Is there any way that I could add this jQuery easing animation to the scroll movement? jQuery.extend( jQuery.easing, { easeInOutBack: function (x, t, b, c, d, s) { if (s == undefined) s = 1.70158; if ((t/=d/2) < 1) return c/2*(t*t*(((s*=(1.525))+1)*t - s)) + b; return c/2*((t-=2)*t*(((s*=(1.525))+1)*t + s) + 2) + b; } }); Thank you so much in advance!

  • Discrete mathematics problem - Probability theory and counting

    - by Mohammad
    Hello All, I'm taking a discrete mathematics course, and I encountered a question and I need your help. I don't know if this is the right place for that though :) It says: Each user on a computer system has a password, which is six to eight characters long, where each character is an uppercase letter or a digit. Each password must contain at least one digit. How many possible passwords are there? The book solves this by adding the probabilities of having six,seven and eight characters long password. However, when he solves for probability of six characters he does this P6 = 36^6 - 26^6 and does P7 = 36^7 - 26^7 and P8 = 36^8 - 26^8 and then add them all I understand the solution, but my question is why doesn't calculating, P6 = 10*36^5 and the same for P7 and P8, work? 10 for the digit and 36 for the alphanumeric? Also, if anyone could give me another solution, other than the one in the book. Thank you very much :)

  • How to make php-closure compiler output to a predefined file name? (Updated)

    - by Mohammad
    Php-closure compiler (linked to source code) currently writes the compiled code to a md5 encoded filename. How can I make it so it write the compiled code to a predefined name like compiled_code.js? . . I think it has to do with the write() function on Line 164. It gets the filename via the _getCacheFileName() function (Line 272). function _getCacheFileName() { return $this->_cache_dir . $this->_getHash() . ".js"; } I've tried altering it to this: function _getCacheFileName() { //return $this->_cache_dir . $this->_getHash() . ".js"; return 'copiled_code.js'; } without any results. Thanks to all of you in advance!

    When Yahoo! developer guide says "Deploying your content across multiple, geographically dispersed servers will make your pages load faster from the user's perspective". And as an explanation I read somewhere, that browsers will load up to 5 things simultaneously from the same domain.
