    - by fzshah76
    I've got an Ajax call for log in here is the code: //if MOUSE class is clicked $('.mouse').click(function () { //get the form to submit and return a message //how to call the function var name = $('#name').val(); var pwd2 = $('#pwd2').val(); $.ajax({ type:"POST", url: "http://localhost:51870/code/Login.aspx", data: "{ 'name':'" + $('#name').val() + "', 'pwd':'" + $('#pwd2').val() + "' }", contentType: "application/json; charset=utf-8", dataType: "json", context: document.body, success: function () { //$(this).addClass("done"); $(this).hide(); $('.mouse, .window').hide(); } }); }); the problem is I can't seem to catch name and pwd variables in Login page's preinit event or page load event here is the code in c#: protected void Page_PreInit(object sender, EventArgs e) { //taking javascript argument in preinit event //from here I'll have to build the page for specific lookbook var name = Request.QueryString["name"]; var pwd = Request.QueryString["pwd"]; } protected void Page_Load(object sender, EventArgs e) { var name = Request.QueryString["name"]; var pwd = Request.QueryString["pwd"]; SignIn(name); } I can't seem to get username name and password in c# side, help is appreciated.

  • How can I set the name of the class xml by constructor?

    - by spderosso
    Hi, I want to be able to do something like this: @Root(name="events") class XMLEvents { @ElementList(inline=true) ArrayList<XMLEvent> events = Lists.newArrayList(); XMLEvents(){ ... events.add(new XMLEvent(time, type, professorP)); events.add(new XMLEvent(time, type, student)); events.add(new XMLEvent(time, type, course)); ... } } The XMLEvent class to go something like: class XMLEvent { @Root(name="professor") XMLEvent(DateTime time, LogType type, Professor p){ ... } @Root(name="student") XMLEvent(DateTime time, LogType type, Student st){ ... } @Root(name="course") XMLEvent(DateTime time, LogType type, Course c){ ... } } For the output to be: <events> <professor> ... </professor> <student> ... </student> <course> ... </course> </events> So depending on the constructor I call to create a new XMLEvent the root name to which is mapped is different. Is this even possible? Of course the past example was just to transmit what I need. Putting the @Root annotation there didn't change anything Thanks!

  • How to save XML file before update?

    - by Robert Iagar
    Right so I have a simple app that consists of a calendar a Set Event button and list box that populates using a DataTemplate in WPF. When I build the app the Events.xml file is like this: <?xml version="1.0" encoding="utf-8" ?> <events> </events> I add events to xml through code. Final structure of the xml file is the following <?xml version="1.0" encoding="utf-8" ?> <events> <event Name="Some Name"> <startDate>20.03.2010</startDate> <endDate>29.03.2010</endDate> </event> </event> Now here's my problem. If I update the app and deploy it with Click Once and the app updates it self, I lose the list because the new file is empty. Any workaround this? Here's how I add the Data: var xDocument = XDocument.Load(@"Data\Events.xml"); xDocument.Root.Add(new XElement("event", new XAttribute("name", event.Name), new XElement("startDate", startDate), new XElement("endDate", endDate) ) ); xDocument.Save(@"Data\Events.xml");

  • Big task - problems with page refresh and ajax

    - by user1830414
    I have a navigation which load dynamically content via ajax. But if I refresh the page or visit another url and go back the current content is away and I see the old content under the first menu tab. Now I have to solve this problem. The index.php include the elements header_registrated.inc.php, navigation.inc.php and main_container.inc.php index.php: <?php include("inc/incfiles/header_registrated.inc.php"); ?> <?php if (!isset($_SESSION["userLogin"])) { echo "<meta http-equiv=\"refresh\" content=\"0; url=http://localhost/project\">"; } else { echo ""; } ?> <?php include("inc/incfiles/navigation.inc.php"); ?> <?php include("inc/incfiles/main_container.inc.php"); ?> <?php include("inc/incfiles/footer.inc.php"); ?> header_registrated.inc.php: <?php include ("inc/scripts/mysql_connect.inc.php"); session_start(); $user = $_SESSION["userLogin"]; ?> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>title</title> <link href="css/style.css" rel="stylesheet" type="text/css" /> <script language="JavaScript" src="js/framework/jquery.js"></script> <script language="JavaScript" src="js/dropdown/window.js"></script> <script language="JavaScript" src="js/navigation/navigation.js"></script> </head> <body> </body> navigation.inc.php: <div class="navigation"> <ul> <li id="1"> <div id="menuImage1" class="menuImage"></div> <div class="menuText"><p>Punkt 1</p></div> <div class="navigationDart"></div> </li> <li id="2"> <div id="menuImage2" class="menuImage"></div> <div class="menuText"><p>Punkt 2</p></div> </li> <li id="3"> <div id="menuImage3" class="menuImage"></div> <div class="menuText"><p>Punkt 3</p></div> </li> <li id="4"> <div id="menuImage4" class="menuImage"></div> <div class="menuText"><p>Punkt 4</p></div> </li> <li id="5"> <div id="menuImage5" class="menuImage"></div> <div class="menuText"><p>Punkt 5</p></div> </li> <li id="6"> <div id="menuImage6" class="menuImage"></div> <div class="menuText"><p>Punkt 6</p></div> </li> </ul> </div> main_container.inc.php: <div class="mainContainer"> <div class="containerHeader"> <div class="contentHeader"> </div> </div> <div class="contentContainer"> <div class="content"> </div> <div class="advertisement"> </div> </div> </div> Now the divs content, cnotentHeader and advertisement (in file main_content.inc.php) is filled via ajax.

Please help me. I have the feeling that I've searched the whole web to find an answer.

    - by ChrisWesAllen
    I have a model of events that has various information such as date, location, and description of whats going on. I would like for my users to be able to search through the events list through a set of different textboxes but I having a hard time getting the syntax just right in my view I have... <% form_tag users_path, :method => 'get' do %> (<%= text_field_tag :search_keyword, params[:search_keyword] %>) + (<%= text_field_tag :search_zip, params[:search_zip] %>) <%= submit_tag "Find Events!", :name => nil %> <% end %> and in the controller I'm trying to query through the results.... if params[:search_keyword] @events = Event.find(:all, :conditions => [' name LIKE ? ', "%#{params[:search_keyword]}%"]) elsif params[:search_zip] @events = Event.find(:all, :origin=> params[:search_zip], :within=>50 ) else @events = Event.find(:all) end How do I code it so that it will perform the search only if the textbox isnt empty? also if both textboxes are filled then @events should be the product of BOTH queries? if have no idea if this would work =(???@event = @event+ event.find.....???

  • Sometimes keyboard & touchpad work... sometimes not

    - by Voyagerfan5761
    When I first ran Ubuntu from CD on this Dell Inspiron 2650, it worked for about ten to fifteen minutes, then it hung (I was probably trying to do too much at once from a Live CD). The next time, my mouse and keyboard didn't work. I rebooted three times and finally got them working. I then installed Ubuntu alongside Windows XP. After installing, selecting the OS in GRUB worked, but my touchpad and keyboard were again not working. I rebooted, and they worked. (I fortunately had a USB mouse with which to reboot.) Booting Ubuntu and then rebooting to enable my keyboard and touchpad has become a routine ever since. Often several reboots are required; at one point I had to reboot over a dozen times in a row before getting a session where everything worked properly. (My installation has been in place for about three days a week now.) I've looked around for a device manager equivalent to no avail. Sometimes the hardware is properly detected, and sometimes it's not. Once or twice I've had the keyboard detected properly but the touchpad not. Plugging in my wireless card also sometimes requires a plug, unplug, and plug again to get it working. So is there some solution? I'm without an Internet connection at home, and this "laptop" is really a wall wart on my desk, so suggestions for packages may take a while to test. Xorg logs I captured two three four sample Xorg logs: one from a startup where the devices worked; one from when they didn't; one from a session where Ubuntu thought my touchpad was a normal mouse; and one from a session where my keyboard worked but the touchpad didn't. See this gist. Updated 2010-12-15 01:50 UTC with Xorg.0.log.keyboardonly file illustrating the case where the keyboard worked but not the touchpad. Updated 2011-01-11 04:10 UTC with Xorg.0.log.touchpadregmouse to illustrate a case where the touchpad was detected as a regular mouse (no "Touchpad" tab in mouse prefs).

  • Visual Studio 2010/2012 Context Menus and a Keyboard

    - by SergeyPopov
    As a software developer, I spend a lot of time using Visual Studio. I have to say that I completely satisfied with Visual Studio generally. Nevertheless, sometimes Visual Studio starts annoying me. One issue which poisoned my existence for a long time is that context menu behavior in VS2010 is a little different than it was in VS2005/2008. Unfortunately, in VS2012 this behavior remains the same as in VS2010. So, what is the issue? Working with Visual Studio, I use the keyboard in most cases. I also use the Apps key on the keyboard to open context menus in the code editor. Moreover, long time ago I am got used to using some key sequences, and press the keys without even thinking. In VS2008, a mouse pointer position didn’t affect context menu navigation if I used the keyboard. Every time I opened a context menu I was sure that, for example, the "Apps, Down, Down, Enter, Up, Enter" key sequence always invoke "Organize Usings > Remove and Sort" function. But in VS2010, this behavior has been changed. If a mouse pointer is located over an opened context menu, the menu item under the mouse pointer becomes selected immediately! So, now the "Apps, Down, Down, Enter, Up, Enter" key sequence will not lead to expected results all the time. In some cases, the result may be a little scary. If you are using Visual SVN extension, this key sequence may invoke "Revert whole file" function. Of course, this is not a fatal problem because "Undo" function restores all the changes, but this behavior strongly annoys me. In Visual Studio 2012, context menu behavior is a little different than in VS2010, but a mouse pointer position still affects the keyboard navigation in the context menu, and this behavior is still annoying. I tried to find the way how to change this behavior, but I didn’t manage to find the answer quickly. Then I decided to go right though, so I wrote a small utility which fixes this issue. This utility watches for Apps key, and if the key is pressed in Visual Studio, the utility moves the mouse pointer to the top of the screen before opening the context menu. You can find binaries and the source code of this utility here: http://code.google.com/p/vs-ctx-menu-fix/downloads/list This utility works fine in Windows 7 and Windows 8 x64. I wrote the first version in January, 2011; now I just added Visual Studio 2012 support. I hope you will find this utility useful! :)

  • Massive number of context switches on ksoftirqd

    We have two servers that are grinding to a halt. One is a VM and the other is bare metal. Neither of them are running similar code but they are on the same network.

  • Trying to convert openGL to MFC coordinates and having Problems with "gluProject"

    - by Erez
    Hi, i'm trying to find the naswer on the web and can't find a full solution that i can use and that will work... I'm developing a MFC project with static picture as the canvas for an openGL class that draw the grphics for my game. On moush down, i need to retrive a shape coordinate from the openGL class. I'm looking for a way to convert the openGL coordinates to MFC coordinates but no matter what i try i get junk after using the gluProject or gluUnProject (i've tried to do both ways but non is working) GLdouble modelMatrix[16]; glGetDoublev(GL_MODELVIEW_MATRIX,modelMatrix); GLdouble projMatrix[16]; glGetDoublev(GL_PROJECTION_MATRIX,projMatrix); int viewport[4]; glGetIntegerv(GL_VIEWPORT,viewport); POINT mouse; // Stores The X And Y Coords For The Current Mouse Position GetCursorPos(&mouse); // Gets The Current Cursor Coordinates (Mouse Coordinates) ScreenToClient(hWnd, &mouse); GLdouble winX, winY, winZ; // Holds Our X, Y and Z Coordinates winX; = (float)point.x; // Holds The Mouse X Coordinate winY; = (float)point.y; // Holds The Mouse Y Coordinate winY = (float)viewport[3] - winY; glReadPixels(winX, winY, 1, 1, GL_DEPTH_COMPONENT, GL_FLOAT, &winZ); GLdouble posX=s1->getPosX(), posY=s1->getPosY(), posZ=s1->getPosZ(); // Hold The Final Values gluUnProject( winX, winY, winZ, modelMatrix, projMatrix, viewport, &posX, &posY, &posZ); gluProject(posX, posY, posZ, modelMatrix, projMatrix, viewport, &winX, &winY, &winZ); This is just part of the code i've tried. ofcourse not gluProject and gluUnProject together. just had them both here to show.....and i know there is lots of junk over there, its from some of my tries... p.s. i've tried many many more combinations and examples from the web and nothing seem to work in my case.... Can any one show me what is the right way to do the transformation? 10x

  • Java app makes screen display unresponsive after 10 minutes of user idle time

    - by Ross
    I've written a Java app that allows users to script mouse/keyboard input (JMacro, link not important, only for the curious). I personally use the application to automate character actions in an online game overnight while I sleep. Unfortunately, I keep coming back to the computer in the morning to find it unresponsive. Upon further testing, I'm finding that my application causes the computer to become unresponsive after about 10 minutes of user idle time (even if the application itself it simulating user activity). I can't seem to pin-point the issue, so I'm hoping somebody else might have a suggestion of where to look or what might be causing the issue. The relevant symptoms and characteristics: Unresponsiveness occurs after user is idle for 10 minutes User can still move the mouse pointer around the screen Everything but the mouse appears frozen... mouse clicks have no effect and no applications update their displays, including the Windows 7 desktop I left the task manager up along the with the app overnight so I could see the last task manager image before the screen freezes... the Java app is at normal CPU/Memory usage and total CPU usage is only ~1% After moving the mouse (in other words, the user comes back from being idle), the screen image starts updating again within 30 minutes (this is very hit and miss... sometimes 10 minutes, sometimes no results after two hours) User can CTRL-ALT-DEL to get to Windows 7's CTRL-ALT-DEL screen (after a 30 second pause). User is still able to move mouse pointer, but clicking any of the button options causes the screen to appear to freeze again On some very rare occasions, the system never freezes, and I come back to it in the morning with full responsiveness The Java app automatically stops input scripting in the middle of the night, so Windows 7 detects "real" idleness and turns the monitors into Standby mode... which they successfully come out of upon manually moving the mouse in the morning when I wake up, even though the desktop display still appears frozen Given the symptoms and characteristics of the issue, it's as if the Java app is causing the desktop display of the logged in user to stop updating, including any running applications. Programming concepts and Java packages used: Multi-threading Standard out and err are rerouted to a javax.swing.JTextArea The application uses a Swing GUI awt.Robot (very heavily used) awt.PointerInfo awt.MouseInfo System Specs: Windows 7 Professional Java 1.6.0 u17 In conclusion, I should stress that I'm not looking for any specific solutions, as I'm not asking a very specific question. I'm just wondering if anybody has run into a similar problem when using the Java libraries that I'm using. I would also gladly appreciate any suggestions for things to try to attempt to further pinpoint what is causing my problem. Thanks! Ross PS, I'll post an update/answer if I manage to stumble across anything else while I continue to debug this.

  • Optimizing GDI+ drawing?

    - by user146780
    I'm using C++ and GDI+ I'm going to be making a vector drawing application and want to use GDI+ for the drawing. I'v created a simple test to get familiar with it: case WM_PAINT: GetCursorPos(&mouse); GetClientRect(hWnd,&rct); hdc = BeginPaint(hWnd, &ps); MemDC = CreateCompatibleDC(hdc); bmp = CreateCompatibleBitmap(hdc, 600, 600); SelectObject(MemDC,bmp); g = new Graphics(MemDC); for(int i = 0; i < 1; ++i) { SolidBrush sb(Color(255,255,255)); g->FillRectangle(&sb,rct.top,rct.left,rct.right,rct.bottom); } for(int i = 0; i < 250; ++i) { pts[0].X = 0; pts[0].Y = 0; pts[1].X = 10 + mouse.x * i; pts[1].Y = 0 + mouse.y * i; pts[2].X = 10 * i + mouse.x; pts[2].Y = 10 + mouse.y * i; pts[3].X = 0 + mouse.x; pts[3].Y = (rand() % 600) + mouse.y; Point p1, p2; p1.X = 0; p1.Y = 0; p2.X = 300; p2.Y = 300; g->FillPolygon(&b,pts,4); } BitBlt(hdc,0,0,900,900,MemDC,0,0,SRCCOPY); EndPaint(hWnd, &ps); DeleteObject(bmp); g->ReleaseHDC(MemDC); DeleteDC(MemDC); delete g; break; I'm wondering if I'm doing it right, or if I have areas killing the cpu. Because right now it takes ~ 1sec to render this and I want to be able to have it redraw itself very quickly. Thanks In a real situation would it be better just to figure out the portion of the screen to redraw and only redraw the elements withing bounds of this?

    (I'm using the Mac version MS Word 2011) I used to happily use the wheel mouse to zoom but, after upgrading to the Mac Magic mouse (using only finger slide movement to scroll and pan) I can no longer hold Ctrl and roll the mouse to zoom (driving me crazy) and I can't see a useful keyboard shortcut and the zoom slider bar in the lower right of the Word screen isn't practical (in my experience). Is there any way to zoom in on the Mac Version of Microsoft Word 2011 without resorting to using a menu?

  • KVM Switch for multiple monitors possible?

    - by jasondavis
    I have been curious about this for YEARS! I have never used a KVM switch (keyboard, mouse, monitor) switch to allow you to use 1 keyboard, mouse, monitor to operate 2 or more computers however I understand the concept and what they are for, just never really had a huge need for 1 until now. Here is my issue though. If possible I need to have a KVM switch hooked up to 2 computers in my room. The catch, I have 2-3 monitors on the PC, so I am looking for a way to have a KVM switch that will support multiple monitors. So PC #1 can be using a mouse, keyboard, 2-3 monitors like normal. I then hit the switch and it makes my mouse, keyboard, and 2-3 monitors switch to PC #2. Has anyone ever heard of a KVM switch being able to support multiple monitors like I described? Or how I can achieve this goal? Please help.

  • A fatal exception 0E occured at 0028:xxxxxx in VxD IOS(01)

    - by winlin
    I get a blue screen of death in my windows 98 machine every time I boot it. I can't reach to my desktop. The error is like this: A fatal exception 0E occured at 0028:C003CC2F in VxD IOS(01) + 0000156B This was called from 0028:C0082E60 in VxD VKD(01) + 000001D0 I have to then give it a three finger salute to restart the system.

  • Scroll wheel causes browsers + Windows explorer to go back

    - by KaptajnKold
    I use Windows 7 on a VirtualBox VM on a Mac. Lately, when I'm using any browser (IE9, Chrome or FireFox or even Windows Explorer), use of the scroll wheel followed by any movement of the mouse cursor causes the browser to go back. Very annoying. This happens when I use the scroll wheel on a USB connected mouse (brand/model unknown, since I don't have it in front of me as I write this) or when I use two-finger scrolling on the trackpad when no mouse is connected. When I connect from my VM to a remote Windows box (Windows Server 2008), I experience the same problem. I have tried rebooting the VM to no avail. I am not sure when the problem started exactly. It may or may not have been after I connected the USB mouse for the first time, but trying to unplug it and then rebooting didn't help. I have tried to google for a solution, but all I've found are people who accidentally pressed the shift key while scrolling, which will cause the browser to go backward or forward in the browser history. This however is not the problem I'm having. To be clear, in my case the browser only goes back when I move the mouse after I've used the scroll wheel. I'm at my wits end :(

  • Why Does My Windows 7 PC Freeze After Waking from Sleep?

    - by Blaenk
    Hey guys. I have Windows 7 running on my computer and everything is perfect. There's only one little problem. Sometimes when I leave my computer, I come back and my monitor is turned off or asleep, whichever it is. This is fine, I set it to do this. However, after turning on the monitor and moving the mouse around, the mouse cursor freezes; both the keyboard and mouse don't respond to anything, for example the keyboard's windows key won't bring up the start menu and moving the mouse around does not move the cursor around on the screen. I have to wait about a minute or two before things start working again. I figured this was a power savings setting problem, so I went into Control Panel Power Options. I only have Turn off Display = 30 minutes and Put Computer to Sleep = Never. Of course, I went into the advanced power settings to look through there. I put Never to turn off the hard disk, Sleep after never, and that's about it. Nothing else there looks like it might be causing this. I went into the device manager and checked the mouse and the keyboard, and they both have the Allow this device to wake the computer checked for both of them. Perhaps this other bit of information might help: Sometimes I VNC into my PC using my MacBook, and sometimes, as soon as it shows me the desktop, the same thing happens. The mouse won't move and VNC won't register any events on the server (Which is my PC of course). I close the client (And I know it has nothing to do with the client), then immediately restart it and try to connect. When I click the connect button, it hangs there, as if the PC is not responding. Basically it's like whenever I try to wake the computer from sleep, it does so by showing me the desktop, then it freaks out. Then again, I guess the computer isn't sleeping because the setting is set to 'Sleep after = Never'. I honestly don't know what's going on, would appreciate any insight. Thanks!

  • photoshop - How to show the cursor coordinate in selection and dropper

    - by q0987
    I am using Adobe Photoshop CS4 to edit a picture. The problems I have are that I don't know where I can see the mouse cursor coordinate while I move my mouse. Q1 For example, in Paint.Net, whenever I move mouse cursor, I can immediately see the feedback from bottom-right corner (x, y), how can I see such info in photoshop while I use eyedropper function? Q2 For example, when in crop mode, I drag-drop a rectangle but I cannot see the size of the created region of interest? Thank you

  • Qt QAbstractButton setDown interferes with grabMouse

    - by edA-qa mort-ora-y
    I have some weird behaviour in Qt that seems like a defect. I'd like to know if anybody has a good workaround. I have a popup widget that contains many buttons in it. The user activates the popup by pressing the mouse button down. The popup widget calls grabMouse when shown. It gets all the mouse events. As it rolls over a button it calls setDown(true) on the button. Now however, when the mouse button is released the popup widget does not get the mouseReleaseEvent, that goes to the button. That is, calling setDown(true) on a button causes the button to steal mouse events, bypassing the grabMouse in the popup widget. I've looked at the source code for setDown but I can't see anything there that would do it directly. I also notice however that sometimes a button gets a hover event, sometimes not. I would assume it would never get those events when the mouse is grabbed. //g++ -o grab_lost grab_lost.cpp -lQtCore -lQtGui -I /usr/include/qt4/ -I /usr/include/qt4/QtCore -I /usr/include/qt4/QtGui /** Demonstrates the defect of losing the mouse. Run the program and: 1. Press mouse anywhere 2. release in purple block (not on X) 3. Release message written (GrabLost receives the mouseReleaseEvent) For defect: 1. Pree mouse anywhere 2. Release inside the X button 3. button is clicked, no release message (GrabLost does not get the mouseReleaseEvent) */ #include <QWidget> #include <QPushButton> #include <QApplication> #include <QMouseEvent> #include <QPainter> class GrabLost : public QWidget { QPushButton * btn; public: GrabLost( QWidget * parent = 0) : QWidget( parent, Qt::Popup ) { btn = new QPushButton( "X", this ); setMouseTracking( true ); } protected: void showEvent( QShowEvent * ev ) { QWidget::showEvent( ev ); grabMouse(); } void closeEvent( QCloseEvent * ev ) { releaseMouse(); QWidget::closeEvent( ev ); } void hideEvent( QHideEvent * ev ) { releaseMouse(); QWidget::hideEvent( ev ); } void mouseReleaseEvent( QMouseEvent * ev ) { qDebug( "mouseRelease" ); close(); } void mouseMoveEvent( QMouseEvent * ev ) { QWidget * w = childAt( ev->pos() ); bool ours = dynamic_cast<QPushButton*>( w ) == btn; btn->setDown( ours ); } void paintEvent( QPaintEvent * ev ) { //just to show where the widget is QPainter pt( this ); pt.setPen( QColor( 0,0,0 ) ); pt.setBrush( QColor( 128,0,128) ); pt.drawRect( 0, 0, size().width(), size().height() ); } }; class GrabMe : public QWidget { protected: void mousePressEvent( QMouseEvent * ev ) { GrabLost * gl = new GrabLost(); gl->resize( 100, 100 ); QPoint at( mapToGlobal( ev->pos() ) ); gl->move( at.x() - 50, at.y() - 50 ); gl->show(); } }; int main( int argc, char** argv ) { QApplication app( argc, argv ); GrabMe * gm = new GrabMe(); gm->move( 100, 100 ); gm->resize( 300, 300 ); gm->show(); app.exec(); return 0; }

  • Two Phase Commit with MongoDB

    - by mattcodes
    Heres what Im thinking. Do you see any issues with this workaround to emulate 2 phase commit when using something like MongoDB where each operation is atomic and there is no support for transactions outside of that? transaction_scope: read message from servicebus - UpdateCustomerAddress get customer aggregate from docdb, replay events where commited =1 call customer.updateAddress validates creates customer address updated event apply event event store as uncommitted events do optimistic concurrency update against docdb pushing uncommitted events (single op to ensure consistency) publish event to service bus update docdb set events just published to commited = 1 (again one 1 op - at least in mongodb) transaction_complete

  • Logitech MX3200 keyboard stopped working

    - by Roy Rico
    I have a Logitech MX3200 wireless keyboard and mouse set, and keyboard stopped working. I was working with it and it just stopped in the middle of using it. Some notes: The mouse still works flawlessly, i've tried to reconnect the KB i've tried to reconnect everything, mouse reconnects, keyboard reconnects (or pretends to) I've tried to hard reset (holding the connect button on the receiver for 10 seconds). I've tried new batteries I took out the batteries out of the KB & Mouse and unplugged the receiver over night. The media keys still work (launches winamp) but they main keys does not At this point, i've tried everything I've seen online. I just want to know is my keyboard dead in the water? I would say it's been about 8 months to a year since i've bought it, and the articles i find on the internet all say that's as long as they last... is this true? what's everyone's experience? I hope it's not true.

  • populate CoreData data model from JSON files prior to app start

    - by johannes_d
    I am creating an iPad App that displays data I got from an API in JSON format. My Core Data model has several entities(Countries, Events, Talks, ...). For each entity I have one .json file that contains all instances of the entity and its attributes as well as its relationships. I would like to populate my Core Data data model with these entities before the start of the App (otherwise it takes about 15 minutes for the iPad to create all the instances of the entities from the several JSON files using factory methods). I am currently importing the data into CoreData like this: -(void)fetchDataIntoDocument:(UIManagedDocument *)document { dispatch_queue_t dataQ = dispatch_queue_create("Data import", NULL); dispatch_async(dataQ, ^{ //Fetching data from application bundle NSURL *tedxgroupsurl = [[NSBundle mainBundle] URLForResource:@"contries" withExtension:@"json"]; NSURL *tedxeventsurl = [[NSBundle mainBundle] URLForResource:@"events" withExtension:@"json"]; //converting the JSON files to NSDictionaries NSError *error = nil; NSDictionary *countries = [NSJSONSerialization JSONObjectWithData:[NSData dataWithContentsOfURL:countriesurl] options:kNilOptions error:&error]; countries = [countries objectForKey:@"countries"]; NSDictionary *events = [NSJSONSerialization JSONObjectWithData:[NSData dataWithContentsOfURL:eventsurl] options:kNilOptions error:&error]; events = [events objectForKey:@"events"]; //creating entities using factory methods in NSManagedObject Subclasses (Country / Event) [document.managedObjectContext performBlock:^{ NSLog(@"creating countries"); for (NSDictionary *country in countries) { [Country countryWithCountryInfo:country inManagedObjectContext:document.managedObjectContext]; //creating Country entities } NSLog(@"creating events"); for (NSDictionary *event in events) { [Event eventWithEventInfo:event inManagedObjectContext:document.managedObjectContext]; // creating Event entities } NSLog(@"done creating, saving document"); [document saveToURL:document.fileURL forSaveOperation:UIDocumentSaveForOverwriting completionHandler:NULL]; }]; }); dispatch_release(dataQ); } This combines the different JSON files into one UIManagedDocument which i can then perform fetchRequests on to populate tableViews, mapView, etc. I'm looking for a way to create this document outside my application & add it to the mainBundle. Then I could copy it once to the apps DocumentsDirectory and be able I use it (instead of creating the Document within the app from the original JSON files). Any help is appreciated!
