  • WS2008 NTP - Using time.windows.com,0x9 - Time always skewed forwards

    - by David
    I have a domain controller configured to use time.windows.com (with 0x09 flags set). I've noticed that frequently the systems' clock is fast - it varies from 10 minutes to even 45 minutes. I always have to keep resetting the system date/time back to what it should be. When I run "w32tm /query /source" it tells me it's using time.windows.com, and obviously I trust Microsoft not to serve incorrect times, but why is my server's clock fast? EDIT: There are a few Time-Service events in the System log: Event ID: 142 Message: The time service has stopped advertising as a time source because the local clock is not synchronized. Event ID: 139 Message: The time service has started advertising as a time source. These two messages appear in pairs every hour or so. Event 142 appears 14 to 16 minutes after 139 appears. Going back a few months, these events appear: Event ID: 35 Message: The time service is now synchronizing the system time with the time source time.windows.com,0x9 (ntp.m|0x9|0.0.0.0:123-65.55.21.21:123). Event ID: 37 Message: The time provider NtpClient is currently receiving valid time data from time.windows.com,0x9 (ntp.m|0x9|0.0.0.0:123-65.55.21.21:123). Event ID: 47 Message: Time Provider NtpClient: No valid response has been received from manually configured peer time.windows.com,0x9 after 8 attempts to contact it. This peer will be discarded as a time source and NtpClient will attempt to discover a new peer with this DNS name. The error was: The time sample was rejected because: The peer is not synchronized, or it has been too long since the peer's last synchronization. These three events only appear once in the log, back in October.

  • Domain workstation acting up and I can't track it down.

    - by DevNULL
    I have a developer with a Windows XP (SP2) 64 bit machine.

  • Trouble with Remote Desktop pulling through printers. Drive Redirection works, and the ports created but not the printers

    - by Windex
    I've run out of things to look into. All the support documents have been gone through and still provide no resolution. I've checked the service permissions, (sc sdshow spooler) they all match up with other systems and what is output on the support documents. I'm nearly positive that the issue can't be permissions anyway as the software requires all users to be an administrator, so all users are a local administrator. (I haven't looked into why yet but its on the list, I was just recently brought into this team and we've put procedures in place for quick recovery.) We've applied hot fixes relating to RDS and printing, though I'm not sure which ones they were. I've combed through group policy and no where is printer redirection disabled. It's setup with all default values regarding the use and redirection of printers and a quick install of W2k8 R2 shows that it works by default. This dev install was joined to the same domain, placed in the same OU, shows the same policies applied, etc, etc, etc, The server generates all the correct redirected ports but no printers are created. It will also redirect drives without issue, this would seem to rule out the usermode service that handles redirects being broken. No events are logged related to any of the events and there are no events from the TerminalServices-Printer source. There were local printers setup. I didn't think it would mattter but as I was running out of ideas I tried deleting them all with no change. The TS was configured for the software it will be running before we checked out the redirection of printers so the other team responsible to setting up new servers wants to find a fix instead of reloading a new server. I'm not sure where or what else to look for. Any ideas?

  • Notification framework for java

    - by rmarimon
    I'm in the process of developing a web application (java + jsp) that can send notifications to users. The user can subscribe to multiple events generated by the application and can choose to receive the messages associated with those events via multiple channels (email, sms, growl?, messenger); perhaps different messages through different channels; perhaps a daily message digest. Everything must be configurable by the user. Is there some framework that deals with this?

  • Horizontal UITableView

    - by imran
    I want implement a layout in my ipad application that has a uitable view that scrolls left and right rather then up and down : So rather than row 1 row 2 row 3 ( scrolling vertically ) It would be : row 1, row2, row 3 (scrolling horizontally ) I've seen that UItableView is designed to only do vertical scrolling so doing a transform does not give the desired effect. Is there a standard way to do this taking advantage of a datasource provider like uitableview provides? I basically want to do somthing similar to what the BBC News reader app ( http://itunes.apple.com/us/app/bbc-news/id364147881?mt=8 ) on the Ipad does with the list of stories to select from. Thanks

  • Bugs in Excel's ActiveX combo boxes?

    - by k.robinson
    I have noticed that I get all sorts of annoying errors when: I have ActiveX comboboxes on a worksheet (not an excel form) The comboboxes have event code linked to them (eg, onchange events) I use their listfillrange or linkedcell properties (clearing these properties seems to alleviate a lot of problems) (Not sure if this is connected) but there is data validation on the targeted linkedcell. I program a fairly complex excel application that does a ton of event handling and uses a lot of controls. Over the months, I have been trying to deal with a variety of bugs dealing with those combo boxes. I can't recall all the details of each instance now, but these bugs tend to involve pointing the listfillrange and linkedcell properties at named ranges, and often have to do with the combo box events triggering at inappropriate times (such as when application.enableevents = false). These problems seemed to grow bigger in Excel 2007, so that I had to give up on these combo boxes entirely (I now use combo boxes contained in user forms, rather than directly on the sheets). Has anyone else seen similar problems? If so, was there a graceful solution? I have looked around with Google and so far haven't spotted anyone with similar issues. Some of the symptoms I end up seeing are: Excel crashing when I start up (involves combobox_onchange, listfillrange-named range on another different sheet, and workbook_open interactions). (note, I also had some data validation on the the linked cells in case a user edited them directly.) Excel rendering bugs (usually when the combo box changes, some cells from another sheet get randomly drawn over the top of the current sheet) Sometimes it involves the screen flashing entirely to another sheet for a moment. Excel losing its mind (or rather, the call stack) (related to the first bullet point). Sometimes when a function modifies a property of the comboboxes, the combobox onchange event fires, but it never returns control to the function that caused the change in the first place. The combobox_onchange events are triggered even when application.enableevents = false. Events firing when they shouldn't (I posted another question on stack overflow related to this). At this point, I am fairly convinced that ActiveX comboboxes are evil incarnate and not worth the trouble. I have switched to including these comboboxes inside a userform module instead. I would rather inconvenience users with popup forms than random visual artifacts and crashing (with data loss).

  • Documentation for Liferay Hooks

    - by Codeflayer
    Hi there, I need to listen for user log in and log out events in Liferay. From what little I've been able to find, it seems that using Liferay hooks would be the way to accomplish this. Unfortunately I haven't been able to find any information other that at the following link: http://www.liferay.com/web/raymond.auge/blog/-/blogs/portal-hook-plugins Does anyone know where I can find further documentation or how I would implement listening for user log in/log out events? Thanks in advance!

  • CSS Rollover button bug

    - by Nick
    Hi Everyone, I'm trying to create a drop down button and its almost working except one little bug. I have several big buttons that change background color when the user hovers over them and one of them, the language button, displays several suboptions inside itself when the user hovers over it. That all works fine except the language button doesn't change its background color when the user hovers over it. It does change its color if the cursor is just inside the button but not if it touches the 3 sub options. What i need is a technique or a rule that states that the button will change background color if user hovers over it or if the user hovers over one of its children elements. How do I achieve this? Here's the markup: <ul> <li><a href="/home/" title="Go to the Home page" class="current"><span>Home</span></a></li> <li><a href="/about-us/" title="Go to the About Us page" class="link"><span>About us</span></a></li> <li><a href="/products/" title="Go to the Products page" class="link"><span>Products</span></a></li> <li><a href="/services/" title="Go to the Services page" class="link"><span>Services</span></a></li> <li><a href="/news/" title="Go to the News page" class="link"><span>News</span></a></li> <li><a href="/dealers/" title="Go to the Dealers page" class="link"><span>Dealers</span></a></li> <li id="Rollover"><a href="" title="select language" class="link"><span>Language</span></a> <ul> <li><a href="/english/">English</a></li> <li><a href="/french/">French</a></li> <li><a href="/spanish/">Spanish</a></li> </ul> </li> <li><a href="/contact-us/" title="Go to the contacts page" class="link"><span>Contact us</span></a></li> </ul> Thanks in advance!

  • How to stop event bubbling with jquery live?

    - by chobo2
    Hi I am trying to stop some events but stopPropagation does not work with "live" so I am not sure what to do. I found this on their site. Live events do not bubble in the traditional manner and cannot be stopped using stopPropagation or stopImmediatePropagation. For example, take the case of two click events - one bound to "li" and another "li a". Should a click occur on the inner anchor BOTH events will be triggered. This is because when a $("li").bind("click", fn); is bound you're actually saying "Whenever a click event occurs on an LI element - or inside an LI element - trigger this click event." To stop further processing for a live event, fn must return false It says that fn must return false so what I tried to do $('.MoreAppointments').live('click', function(e) { alert("Hi"); return false; }); but that did not work so I am not sure how to make it return false. Update Here is some more information. I have a table cell and I bind a click event to it. $('#CalendarBody .DateBox').click(function(e) { AddApointment(this); }); So the AddApointment just makes some ui dialog box. Now the live code(MoreAppointments) sits in this table cell and is basically an anchor tag. So when I click on the anchor tag it first goes to the above code(addApointment - so runs that event first) runs that but does not launch my dialog box instead it goes straight to the (MoreAppointment) event and runs that code. Once that code has run it launches the dialog box from "addApointment". Update 2 Here is some of the html. I did not copy the whole table since it is kinda big and all the cells repeat itself with the same data. If needed I will post it. <td id="c_12012009" class="DateBox"> <div class="DateLabel"> 1</div> <div class="appointmentContainer"> <a class="appointments">Fkafkafk fakfka kf414<br /> </a><a class="appointments">Fkafkafk fakfka kf414<br /> </a><a class="appointments">Fkafkafk fakfka kf414<br /> </a><a class="appointments">Fkafkafk fakfka kf414<br /> </a><a class="appointments">Fkafkafk fakfka kf414<br /> </a> </div> <div class="appointmentOverflowContainer"> <div> <a class="MoreAppointments">+1 More</a></div> </div> </td>

  • AutoScroll issues with custom layout on Windows Forms application

    - by Lurker Indeed
    I've implemented a basic custom layout engine in Windows Forms that does control sizing and positioning. I was hoping to allow the AutoScroll features to work untouched, but any time I have enough controls on the screen to require a scroll bar, some of the layout events that get fired (i.e, a rich text box that expands the height as it types) not only fire the layout events, but they force the scroll bar back at (0,0). Do I have any options besides looking at the scroll position and positioning the controls manually based on that?

  • timeIntervalSinceDate Accuracy

    - by mmccomb
    I've been working on a game with an engine that updates 20 times per seconds. I've got to point now where I want to start getting some performance figures and tweak the rendering and logic updates. In order to do so I started to add some timing code to my game loop, implemented as follows... NSDate* startTime = [NSDate date]; // Game update logic here.... // Also timing of smaller internal events NSDate* endTime = [NSDate date]; [endTime timeIntervalSinceDate:startTime]; I noticed however that when I timed blocks within the outer timing logic that the time they took to execute did not sum up to match the overall time taken. So I wrote a small unit test to demonstrate the problem in which I time the overall time taken to complete the test and then 10 smaller events, here it is... - (void)testThatSumOfTimingsMatchesOverallTiming { NSDate* startOfOverallTime = [NSDate date]; // Variable to hold summation of smaller timing events in the upcoming loop... float sumOfIndividualTimes = 0.0; NSTimeInterval times[10] = {0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0}; for (int i = 0; i < 10; i++) { NSDate* startOfIndividualTime = [NSDate date]; // Kill some time... sleep(1); NSDate* endOfIndividualTime = [NSDate date]; times[i] = [endOfIndividualTime timeIntervalSinceDate:startOfIndividualTime]; sumOfIndividualTimes += times[i]; } NSDate* endOfOverallTime = [NSDate date]; NSTimeInterval overallTimeTaken = [endOfOverallTime timeIntervalSinceDate:startOfOverallTime]; NSLog(@"Sum of individual times: %fms", sumOfIndividualTimes); NSLog(@"Overall time: %fms", overallTimeTaken); STAssertFalse(TRUE, @""); } And here's the output... Sum of individual times: 10.001377ms Overall time: 10.016834ms Which illustrates my problem quite clearly. The overall time was 0.000012ms but the smaller events took only 0.000001ms. So what happened to the other 0.000011ms? Is there anything that looks particularly wrong with my code? Or is there an alternative timing mechanism I should use?

  • jQuery Dialog causing buttons not to post-back

    - by jonathanconway
    I'm using the jQuery UI Dialog() function on an ASP.NET webform, on a particular panel. After Dialog() is applied, the buttons become useless and will not post back at all; I'm not even getting a Page_Load event firing, let alone any button events. Is the Dialog function messing with my button events? If so, is there a way to fix this?

  • When is it worth using a BindingSource?

    - by Justin
    I think I understand well enough what the BindingSource class does - i.e. provide a layer of indirection between a data source and a UI control. It implements the IBindingList interface and therefore also provides support for sorting. And I've used it frequently enough, without too many problems. But I'm wondering if I use it more often than I should. Perhaps an example would help. Let's say I have just a simple textbox on a form (using WinForms), and I'd like to bind that textbox to a simple property inside a class that returns a string. Is it worth using a BindingSource in this situation? Now let's say I have a grid on my form, and I'd like to bind it to a DataTable. Should I use a BindingSource now? In the latter case, I probably would not use a BindingSource, as a DataTable, from what I can gather, provides the same functionality that the BindingSource itself would. The DataTable will fire the the right events when a row is added, deleted, etc so that the grid will automatically update. But in the first case with the textbox being bound to a string, I would probably have the class that contains the string property implement INotifyPropertyChanged, so that it could fire the PropertyChanged event when the string changes. I would use a BindingSource so that it could listen to these PropertyChanged events so that it could update the textbox automatically when the string changes. How does this sound so far? I still feel like there's a gap in my understanding that's preventing me from seeing the whole picture. This has been a pretty vague question so far, so I'll try to ask some more specific questions - ideally the answers will reference the above examples or something similar... (1) Is it worth using a BindingSource in either of the above examples? (2) It seems that developers just "assume" that the DataTable class will do the right thing, in firing PropertyChanged events at the right time. How does one know if a data source is capable of doing this? Is there a particular interface that a data source should implement in order for developers to be able to assume this behaviour? (3) Does it matter what Control is being bound to, when considering whether or not to use a BindingSource? Or is it only the data source that should affect the decision? Perhaps the answer is (and this would seem logical enough): the Control needs to be intelligent enough to listen to the PropertyChanged events, otherwise a BindingSource is required. So how does one tell if the Control is capable of doing this? Again, is there a particular interface that developers can look for that the Control must implement? It is this confusion that has, in the past, led to me always using a BindingSource. But I'd like to understand better exactly when to use one, so that I do so only when necessary.

  • Horizontal "tab"ish scroll between views

    - by Steve Pomeroy
    I'm interested in creating a horizontal scroll view that "snaps" to the viewed item, so only one item is ever shown at a time. The user can touch-drag left/right and will see previous/next views, switching to it if there's enough velocity. This interaction is exactly like what the new weather/news widget that comes with the Nexus One does for navigating between its "tabs". Are there any existing view widgets that do this? Update: found a copy of the news/weather widget (GenieWidget) and they seem to have implemented their own widget to accomplish this which they call com.google.android.apps.genie.geniewidget.ui.FlingableLinearLayout which is part of their own custom com.google.android.apps.genie.geniewidget.ui.TabView. As that source isn't available, that's not looking too hopeful a direction.

  • need help figuring out dynamic menu generation in django

    I need to dynamically generate a code like this in the resulting html: <p>>> gallery one</p> <p><a href="../gallery2">gallery two</a></p> <p><a href="../about">about the author</a></p> <p><a href="../news">our news</a></p> I do have menu_code string variable created in views.py (it is generated depending on an item number of the current page passed — 1 in the case above), which contains that long string with the code shown above. It is (well, supposed to) passed by locals() into the html template (all other variables are passed that way successfully): return render_to_response('gallery_page.html', locals()) I have this: {% include menu_code %} inside the template html. But instead of being interpreted as code it is just shown as text in the browser. What am I doing wrong? How to make it work as a dynamically generated menu?
