  • Question about how AppFabric's cache feature can be used.

    - by Kevin Buchan
    Question about how AppFabric's cache feature can be used. I apologize for asking a question that I should be able to answer from the documentation, but I have read and read and searched and cannot answer this question, which leads me to believe that I have a fundamentally flawed understanding of what AppFabric's caching capabilities are intended for. I work for a geographically disperse company. We have a particular application that was originally written as a client/server application. It’s so massive and business critical that we want to baby step converting it to a better architected solution. One of the ideas we had was to convert the app to read its data using WCF calls to a co-located web server that would cache communication with the database in the United States. The nature of the application is such that everyone will tend to be viewing the same 2000 records or so with only occasional updates and those updates will be made by a limited set of users. I was hoping that AppFabric’s cache mechanism would allow me to set up one global cache and when a user in Asia, for example, requested data that was not in the cache or was stale that the web server would read from the database in the USA, provide the data to the user, then update the cache which would propagate that data to the other web servers so that they would know not to go back to the database themselves. Can AppFabric work this way or should I just have the servers retrieve their own data from the database?

  • Problems with viewing site in Internet Exploder

    - by Kevin
    I built a site and I'm just about finished. It displays properly in all the browsers I have (Safari, Chrome, and Firefox) but my client is not computer savvy at all and still uses Internet Explorer, so that's all he's using to view the site. I don't have IE to test the site so I've been using BrowserStack.com and I see in IE that the site is broken. The navigation bar has a white background and is pushed down a line, and the logo isn't appearing. Could anybody please assist me with figuring out why the site isn't displaying properly in IE, and how to fix it? Help is greatly appreciated. Thanks Site: WebuildCAhomes dot com

  • user_objects oracle

    - by mysticfalls
    I would just like to ask what is the difference between user_constraints and user_objects. I have this two database. I run a script on both DB that resulted a unique constraint error. To solve the problem I delete the constraint on user_constraint table for both DB. After that DB1 run without error.. DB2 however failed, I checked the user_constraint for both db and the constraints was deleted. I was asked to check the user_objects.. and found that DB2 has that same constraint_name as the object_name in user_objects table.. Any info regarding their relationship, use, similarites, etc will be appreciated ... Thanks..

  • How to pass a variable through url and use it inside a controller

    - by anthonypliu
    I have this controller: public ActionResult Details(String UserName) { using (var db = new MatchGamingEntities()) { var Users = from m in db.Users join m2 in db.MyProfiles on m.UserId equals m2.UserId where m.UserName == UserName select new UserViewModel { UserName = m.UserName, LastActivityDate = m.LastActivityDate, Address = m2.Address, City = m2.City, State = m2.State, Zip = m2.Zip }; return View(Users.SingleOrDefault()); } } I type in the url Profiles/Details/hello, but it does not work, if I do Profiles/Details?UserName=hello then it works. I have another ActionResult just like this except taking in an int id as parameter and it works fine with the first url format.

  • linq2sql left join with "multiselect"

    - by just_azho
    Hi, folks I'm trying to achieve following by linq2sql, but not successful. I've Member and Reference tables. DB is design in such a manner that Member can have multiple (=0) References. What I want as a result of query is, list (rows) of members, where all references of the member are "collected" in one column. What I had achieved is following query, but for this one there exist a row for each Reference. var refs = (from m in db.Members join r in db.References on m.PID equals r.PID into g from o in g.DefaultIfEmpty() select new { member = m, name = (o == null ? "" : o.NameSurname) }); I feel I need to insert SelectMany somewher :) Could you please give hints on achieving the goal?

  • Bind Java program to Cocoa interface

    - by Kevin
    Hi, would it be possible to bind a Java application to a Cocoa graphical interface? I'm working in Eclipse right now, on my mac, and am wondering if Interface Builder could be used to construct a new interface so that I don't have to look at Swing all day. Any ideas/suggestions? Thanks!

  • Oracle Reports SELECT INTO Not Selecting

    - by Kevin Cruz
    I'm working on a Report in Oracle Reports Builder, and having issues with my AFTERPFORM trigger. When viewing the report, it seems like the year is being processed properly, while the period and subperiod are using their initial values. I'm confused because they are the exact same select statement, but are not working as intended. Any help would be greatly appreciated! function AfterPForm return boolean is v_subpdenddt_user date; v_subpdenddt_max date; v_rowcount integer; begin select value into year from wos_report_param where parameter = 'year' and sequence_num = :sequencenum; select value into period from wos_report_param where parameter = 'period' and sequence_num = :sequencenum; select value into user_subpd from wos_report_param where parameter = 'subpd' and sequence_num = :sequencenum;

  • Building ffmpeg with an executable output

    - by Kevin Galligan
    I generally don't like to ask such "you figure it out for me" questions, but I suspect this one will be really simple for a C++ guru. I want to build ffmpeg for Android, and I'd like it to output an executable rather than a set of libraries. We've been using the guardian project's build: https://github.com/guardianproject/android-ffmpeg It does produce what we want, but I've found tweaking it for different architectures to be, at best, unpleasant. I've gotten this version to build: https://github.com/appunite/AndroidFFmpeg It does a nice job of slicing and dicing different architectures, but produces a jni version. There is a long story as to why I want the exe, but I'll skip it for now. Is there a flag that needs to be flipped? Some path or other setting? I am at this point fully baffled. Thanks in advance.

  • How can we compute the LAST page with JPA?

    - by Kevin
    I would like to implement pagination in my Servlet/EJB/JPA-Hibernate project, but I can't figure out how only one page from the query and know the number of pages I must display I use setFirstResult(int first) ; setMaxResults(int max) ; and that's working alright, but how can I know how many pages I will have in total? (Hibernate is my JPA provider, but I would prefer using only JPA if possible) UPDATE: COUNT() seems to be the better/easiest solution; but what can be the cost of SELECT COUNT(*) FROM ... in comparison with executeQuery("SELECT * FROM ...).getListResult().size() ?

  • Drupal blocks are syncing?

    - by Kevin
    I am trying to enable a new theme on a site running Drupal 6.16. I enable it fine, it has its own namespace in the theme and theme registry. However when you go to the Blocks section, changing a block here will affect that blocks placement in all the other themes, and vice versa. Is this normal behavior? Where should I begin looking to solve this issue?

  • Android onFling not responding

    - by Kevin Moore
    I am new to android first of all so think of any newbie mistakes first I am trying to add a fling function in my code. public class MainGamePanel extends SurfaceView implements SurfaceHolder.Callback, OnGestureListener { private MainThread thread; private Droid droid; private Droid droid2; private static final String TAG = gameView.class.getSimpleName(); private GestureDetector gestureScanner; public MainGamePanel(Context context){ super(context); getHolder().addCallback(this); droid = new Droid(BitmapFactory.decodeResource(getResources(), R.drawable.playerbox2), 270, 300); droid2 = new Droid(BitmapFactory.decodeResource(getResources(), R.drawable.playerbox2), 50, 300); thread = new MainThread(getHolder(), this); setFocusable(true); gestureScanner = new GestureDetector(this); } public boolean onTouchEvent(MotionEvent event){ return gestureScanner.onTouchEvent(event); } @Override protected void onDraw(Canvas canvas){ canvas.drawColor(Color.BLACK); droid.draw(canvas); droid2.draw(canvas); } @Override public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) { droid.setX(50); droid.setY(50); Log.d(TAG, "Coords: x=" + e1.getX() + ",y=" + e2.getY()); return true; } @Override public boolean onDown(MotionEvent e) { droid2.setX((int)e.getX()); droid2.setY((int)e.getY()); Log.d(TAG, "Coords: x=" + e.getX() + ",y=" + e.getY()); return false; } I got the gestureListener to work with: onDown, onLongPress, and onShowPress. But i can't get any response with onFling, onSingleTapUp, and onScroll. What mistake am I making? does it have to do with views? I don't know what code would be useful to see.... so any suggestions would be much appreciated. Thank You!

  • Help doing a dynamic sort?

    - by Kevin
    I have a notifications table which contains different types of notifications for different events. Inside the table is a notifications_type:string column that contains the type of notification, i.e. "foo" or "bar" or "oof" I want the user to be able to select what notifications they want to display, so there are checkboxes below the result that correspond to prefs_display_foo:boolean, prefs_display_bar:boolean in the User model. What is an elegant way for me to set the :conditions in the find to properly display the sorted results? Also, currently I have it as a method in the user, but how would I do it as a has_many :notifications, :conditions = .....

  • How to give position zero of spinner a prompt value?

  • SQL Join only returning 1 row.

    Not quite sure what I'm missing, but my SQL statement is only returning one row. SELECT tl.*, (tl.topic_total_rating/tl.topic_rates) as topic_rating, COUNT(pl.post_id) - 1 as reply_count, MIN(pl.post_time) AS topic_time, MAX(pl.post_time) AS topic_bump FROM topic_list tl JOIN post_list pl ON tl.topic_id=pl.post_parent WHERE tl.topic_board_link = %i AND topic_hidden != 1 ORDER BY %s I have two tables (post_list and topic_list), and post_list's post_parent links to a topic_list's topic_id. Instead of returning all the topics (where their board's topic_board_link is n), it only returns one topic.
