  • Server 2008 Likes to restart itself

    - by Campo
    I have a weird issue here. I notice about once a week the web server restarts itself. This would be only a minor issue if we were not planning on implementing an IP failover. I have checked the event logs. I don't see anything that indicates a reason for the restart. I need some help diagnosing the reason the server restarts. It happened last night at 5:00AM Last even in the log was 1 hour before the unexpected shutdown. Here is the Log for the shutdown event. Any help is much appreciated. I know there isn't much to go on yet. Log Name: System Source: EventLog Date: 5/5/2010 5:01:12 AM Event ID: 6008 Task Category: None Level: Error Keywords: Classic User: N/A Computer: SERVERNAME Description: The previous system shutdown at 4:56:41 AM on 5/5/2010 was unexpected.

  • Windows phone 7 grouped list

    - by Luke Lowrey
    I am new to silverlight and windows phone 7 development and am having some trouble working out the best way to do a "grouped list". Essentially what I would like to do is group a list of event details by date into something like this: Monday 5/6/10 event 1 event 2 Tuesday 6/6/10 event 3 I tried using nested listboxes which work to certain extent but killed the scrolling. Is that the best way to do grouping (assuming I can fix the scrolling issue) or is there some other method?

  • Detect ANY touch in a view (iPhone SDK)

    - by David
    Hello, I'm currently using ... - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { - (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { to detect swipes. I've got everything working. The only problem is if the user touches on top of something (eg a UIButton or something) the - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { is not called. Is there something like touchesBegan but will work if I touch ANYWHERE on the view? Thanks in advance, David

  • ASP.NET Web Service Throws 401 (unauthorized) Error

    - by user268611
    Hi Experts, I have this .NET application to be run in an intranet environment. It is configured so that it requires Windows Authentication before you can access the website (Anonymous access is disabled). This website calls a web service (enable anonymous access) and the web service calls the DB. We do have a token-based authentication between the web application and the web service to secure the communication between them. The issue I'm facing is that when I deploy this to production, I'm having an intermittent issue whereby the communication between the web application and the web service failed. The 401 issue was thrown. This is actually working fine in our QA environment. Is this an issue with Active Directory? Or could it be an isssue with FQDN as mentioned here: http://support.microsoft.com/default.aspx?scid=kb;en-us;896861? The weirdest thing is that this is happening intermittently when tested in both on the server itself and a remote workstation in my client's environment. But, this is working perfectly in my environment. OS: Windows Server SP1 IIS 6 .NET 3.5 Framework Any idea about the 401 (Unauthorized) issue?? Thx for the help... This is from the log...

  • ItemFocusIn Not Working on Non-Editable DataGrid in Flex

    - by Joshua
    I realize that ItemFocusIn is somehow only applicable to editable datagrids in flex, nevertheless I want to fire an event anytime the user selects a new row in a non-editable datagrid. I have successfully used the CLICK event, but this event is not fired when the user uses the keyboard to select a different row in the datagrid. What do I have to do to cause an event to fire whenever the currently highlighted row in the datagrid changes, regardless of weather it was changed by the mouse or by the keyboard?

  • jquery addresses and live method

When clicking on links in a main nav, the url is updated properly, but when links are loaded dynamically with ajax, the url address function breaks. I have made 'click' events live, allowing for content to be loaded via dynamically loaded links, but I can't seem to make the address event listener live, but this seems to be the only way to make this work. Is my syntax wrong if I change this : $.address.change(function(event) { to this: $.address.live('change', function(event) { or does the live method not work with this plugin?

  • Custom Annotation not showing all

    - by funatsg
    Okay, i have a number of pins on the mapkit. These pins showing different types of attractions. (E.g Parks, Farms and etc) I want to add custom images for these different types of pin. Parks have a park image and vice versa. However, when i added in, not all the images are showing successfully. For example, in parks, it should have 5 pins, but the image only came up in 2 pins, whereas other 3 is in default red pins. But if i used colours to differentiate them. For example, [pinsetPinColor:MKPinAnnotationColorGreen]; It works! Anyone knows what is the problem? Relevant codes below. Tell me if you need more. thanks! - (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation{ if ([annotation isKindOfClass:MKUserLocation.class]) { //user location view is being requested, //return nil so it uses the default which is a blue dot... return nil; } //NSLog(@"View for Annotation is called"); MKPinAnnotationView *pin=[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:nil]; pin.userInteractionEnabled=TRUE; MapEvent* event = (MapEvent*)annotation; NSLog(@"thetype: %@", event.thetype); if ([event.thetype isEqualToString:@"adv"]) { //[pin setPinColor:MKPinAnnotationColorGreen]; pin.image = [UIImage imageNamed:@"padv.png"]; } else if ([event.thetype isEqualToString:@"muse"]){ //[pin setPinColor:MKPinAnnotationColorPurple]; pin.image = [UIImage imageNamed:@"pmuse.png"]; } else if ([event.thetype isEqualToString:@"nightlife"]){ pin.image = [UIImage imageNamed:@"pnight.png"]; } else if ([event.thetype isEqualToString:@"parks"]){ pin.image = [UIImage imageNamed:@"ppark.png"]; } else if ([event.thetype isEqualToString:@"farms"]){ pin.image = [UIImage imageNamed:@"pfarm.png"]; } else { [pin setPinColor:MKPinAnnotationColorRed]; } pin.canShowCallout = YES; pin.animatesDrop = YES; UIButton *rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure]; [rightButton addTarget:self action:@selector(clickAnnotation:) forControlEvents:UIControlEventTouchUpInside]; [rightButton setTitle:event.uniqueID forState:UIControlStateNormal]; pin.rightCalloutAccessoryView = rightButton; return pin; }

  • check keyboard state without using KeyboardEvent in AS3

    - by Pieter888
    Is it possible to check for pressed keys without using the KeyboardEvent? I have an ENTER_FRAME event setup called enterFrameHandler and I want to check within the function enterFrameHandler if any keys are pressed. normally when using a KeyboardEvent I could check for keys easily using a switch that checks the KeyCode of the event, but in an ENTER_FRAME event this isn't possible for me. Is there any other way of checking the keyboard's state within the ENTER_FRAME event?

I tried calling the touchesBegan:, etc. messages, but that did not do anything.

  • Problem with jquery-droppable in Chrome

    - by ripper234
    I have a simple application that users jquery-ui's draggable and droppable. In Firefox, it works perfectly. In Chrome, however, I'm having problems. This is the code: $(".cell").droppable({ drop: function(event, ui) { var originalTarget = event.originalTarget; ... } }); In Chrome the 'event' object is of type 'Object' (using Chrome Dev Kit), and event.originalTarget is 'undefined'. What am I doing wrong?

  • Assigning a vector of one type to a vector of another type

    - by deworde
    Hi, I have an "Event" class. Due to the way dates are handled, we need to wrap this class in a "UIEvent" class, which holds the Event, and the date of the Event in another format. What is the best way of allowing conversion from Event to UIEvent and back? I thought overloading the assignment or copy constructor of UIEvent to accept Events (and vice versa)might be best.

  • Capturing Ctrl-Alt-Del in JavaScript/jQuery

    - by AJ
    While just playing with jQuery/JavaScript I ran across this problem. I could capture Alt and Ctrl keys but NOT Del and certainly not all of them together. $(document).ready(function() { $("#target").keydown(function(event) { if (event.ctrlKey && event.altKey && event.keyCode == '46') { alter("Ctrl-Alt-Del combination"); } }); }); Is it possible to capture all these three keys together?

  • Complex SQL query with group by and two rows in one

    - by Ricket
    Okay, I need help. I'm usually pretty good at SQL queries but this one baffles me. By the way, this is not a homework assignment, it's a real situation in an Access database and I've written the requirements below myself. Here is my table layout. It's in Access 2007 if that matters; I'm writing the query using SQL. Id (primary key) PersonID (foreign key) EventDate NumberOfCredits SuperCredits (boolean) There are events that people go to. They can earn normal credits, or super credits, or both at one event. The SuperCredits column is true if the row represents a number of super credits earned at the event, or false if it represents normal credits. So for example, if there is an event which person 174 attends, and they earn 3 normal credits and 1 super credit at the event, the following two rows would be added to the table: ID PersonID EventDate NumberOfCredits SuperCredits 1 174 1/1/2010 3 false 2 174 1/1/2010 1 true It is also possible that the person could have done two separate things at the event, so there might be more than two columns for one event, and it might look like this: ID PersonID EventDate NumberOfCredits SuperCredits 1 174 1/1/2010 1 false 2 174 1/1/2010 2 false 3 174 1/1/2010 1 true Now we want to print out a report. Here will be the columns of the report: PersonID LastEventDate NumberOfNormalCredits NumberOfSuperCredits The report will have one row per person. The row will show the latest event that the person attended, and the normal and super credits that the person earned at that event. What I am asking of you is to write, or help me write, the SQL query to SELECT the data and GROUP BY and SUM() and whatnot. Or, let me know if this is for some reason not possible, and how to organize my data to make it possible. This is extremely confusing and I understand if you do not take the time to puzzle through it. I've tried to simplify it as much as possible, but definitely ask any questions if you give it a shot and need clarification. I'll be trying to figure it out but I'm having a real hard time with it, this is grouping beyond my experience...

  • Should I define models that will be owned by many different models or use controller and views?

    - by jgervin
    I am struggling to figure out how to get a relationship between several models. I have sales_leads which I need to view by company and by event. So if someone looks up the leads by company they can see all leads across all events, but also see all leads by event. Not sure if this is ownership versus a where? Should it be something like Company.sales_leads where("event.event_id = ?", "2356") Or Models: sales_lead belongs_to event belongs_to company

  • Two Phase Commit with MongoDB

    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

  • Microformat combination to use with events data on a map

    - by Dave Taylor
    I have event data displaying on a map and I am currently using the geo microformat alongside it however it's not particularly rich to have just a list of locations without any details of what they correspond to. I've been looking at combining microformats to achieve this and looking for some thoughts on the subject here is the data i am marking up: event title, event location [latlong], event address, contact phone, link to full details My initial thoughts are to use an hCard along with geo? Is there anything better? Thanks in advance

  • Precise explanation of JavaScript <-> DOM circular reference issue

    - by Joey Adams
    One of the touted advantages of jQuery.data versus raw expando properties (arbitrary attributes you can assign to DOM nodes) is that jQuery.data is "safe from circular references and therefore free from memory leaks". An article from Google titled "Optimizing JavaScript code" goes into more detail: The most common memory leaks for web applications involve circular references between the JavaScript script engine and the browsers' C++ objects' implementing the DOM (e.g. between the JavaScript script engine and Internet Explorer's COM infrastructure, or between the JavaScript engine and Firefox XPCOM infrastructure). It lists two examples of circular reference patterns: DOM element → event handler → closure scope → DOM DOM element → via expando → intermediary object → DOM element However, if a reference cycle between a DOM node and a JavaScript object produces a memory leak, doesn't this mean that any non-trivial event handler (e.g. onclick) will produce such a leak? I don't see how it's even possible for an event handler to avoid a reference cycle, because the way I see it: The DOM element references the event handler. The event handler references the DOM (either directly or indirectly). In any case, it's almost impossible to avoid referencing window in any interesting event handler, short of writing a setInterval loop that reads actions from a global queue. Can someone provide a precise explanation of the JavaScript ↔ DOM circular reference problem? Things I'd like clarified: What browsers are effected? A comment in the jQuery source specifically mentions IE6-7, but the Google article suggests Firefox is also affected. Are expando properties and event handlers somehow different concerning memory leaks? Or are both of these code snippets susceptible to the same kind of memory leak? // Create an expando that references to its own element. var elem = document.getElementById('foo'); elem.myself = elem; // Create an event handler that references its own element. var elem = document.getElementById('foo'); elem.onclick = function() { elem.style.display = 'none'; }; If a page leaks memory due to a circular reference, does the leak persist until the entire browser application is closed, or is the memory freed when the window/tab is closed?

  • List View Selected Index Changed in a multi-selectable list view

    I have a windows form with a listview control. I set the MultiSelect property to true and I added a selected_index changed event. I get the event fired when I click the same index as the current selected index. My expectation is that I will not get the event fired. The strange thing is that the event fired 1 second after I click the index. I appreciate for any reply to explain why this is happening.

  • How does Sentry aggregate errors?

    - by Hugo Rodger-Brown
    I am using Sentry (in a django project), and I'd like to know how I can get the errors to aggregate properly. I am logging certain user actions as errors, so there is no underlying system exception, and am using the culprit attribute to set a friendly error name. The message is templated, and contains a common message ("User 'x' was unable to perform action because 'y'"), but is never exactly the same (different users, different conditions). Sentry clearly uses some set of attributes under the hood to determine whether to aggregate errors as the same exception, but despite having looked through the code, I can't work out how. Can anyone short-cut my having to dig further into the code and tell me what properties I need to set in order to manage aggregation as I would like? [UPDATE 1: event grouping] This line appears in sentry.models.Group: class Group(MessageBase): """ Aggregated message which summarizes a set of Events. """ ... class Meta: unique_together = (('project', 'logger', 'culprit', 'checksum'),) ... Which makes sense - project, logger and culprit I am setting at the moment - the problem is checksum. I will investigate further, however 'checksum' suggests that binary equivalence, which is never going to work - it must be possible to group instances of the same exception, with differenct attributes? [UPDATE 2: event checksums] The event checksum comes from the sentry.manager.get_checksum_from_event method: def get_checksum_from_event(event): for interface in event.interfaces.itervalues(): result = interface.get_hash() if result: hash = hashlib.md5() for r in result: hash.update(to_string(r)) return hash.hexdigest() return hashlib.md5(to_string(event.message)).hexdigest() Next stop - where do the event interfaces come from? [UPDATE 3: event interfaces] I have worked out that interfaces refer to the standard mechanism for describing data passed into sentry events, and that I am using the standard sentry.interfaces.Message and sentry.interfaces.User interfaces. Both of these will contain different data depending on the exception instance - and so a checksum will never match. Is there any way that I can exclude these from the checksum calculation? (Or at least the User interface value, as that has to be different - the Message interface value I could standardise.) [UPDATE 4: solution] Here are the two get_hash functions for the Message and User interfaces respectively: # sentry.interfaces.Message def get_hash(self): return [self.message] # sentry.interfaces.User def get_hash(self): return [] Looking at these two, only the Message.get_hash interface will return a value that is picked up by the get_checksum_for_event method, and so this is the one that will be returned (hashed etc.) The net effect of this is that the the checksum is evaluated on the message alone - which in theory means that I can standardise the message and keep the user definition unique. I've answered my own question here, but hopefully my investigation is of use to others having the same problem. (As an aside, I've also submitted a pull request against the Sentry documentation as part of this ;-)) (Note to anyone using / extending Sentry with custom interfaces - if you want to avoid your interface being use to group exceptions, return an empty list.)

  • CGAffineTransformMakeRotation goes the other way after 180 degrees (-3.14)

    - by TheKillerDev
    So, i am trying to do a very simple disc rotation (2d), according to the user touch on it, just like a DJ or something. It is working, but there is a problem, after certain amount of rotation, it starts going backwards, this amount is after 180 degrees or as i saw in while logging the angle, -3.14 (pi). I was wondering, how can i achieve a infinite loop, i mean, the user can keep rotating and rotating to any side, just sliding his finger? Also a second question is, is there any way to speed up the rotation? Here is my code right now: #import <UIKit/UIKit.h> @interface Draggable : UIImageView { CGPoint firstLoc; UILabel * fred; double angle; } @property (assign) CGPoint firstLoc; @property (retain) UILabel * fred; @end @implementation Draggable @synthesize fred, firstLoc; - (id)initWithFrame:(CGRect)frame { self = [super initWithFrame:frame]; angle = 0; if (self) { // Initialization code } return self; } -(void)handleObject:(NSSet *)touches withEvent:(UIEvent *)event isLast:(BOOL)lst { UITouch *touch =[[[event allTouches] allObjects] lastObject]; CGPoint curLoc = [touch locationInView:self]; float fromAngle = atan2( firstLoc.y-self.center.y, firstLoc.x-self.center.x ); float toAngle = atan2( curLoc.y-(self.center.y+10), curLoc.x-(self.center.x+10)); float newAngle = angle + (toAngle - fromAngle); NSLog(@"%f",newAngle); CGAffineTransform cgaRotate = CGAffineTransformMakeRotation(newAngle); self.transform = cgaRotate; if (lst) angle = newAngle; } -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch =[[[event allTouches] allObjects] lastObject]; firstLoc = [touch locationInView:self]; }; -(void) touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { [self handleObject:touches withEvent:event isLast:NO]; }; -(void) touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { [self handleObject:touches withEvent:event isLast:YES]; } @end And in the ViewController: UIImage *tmpImage = [UIImage imageNamed:@"theDisc.png"]; CGRect cellRectangle; cellRectangle = CGRectMake(-1,self.view.frame.size.height,tmpImage.size.width ,tmpImage.size.height ); dragger = [[Draggable alloc] initWithFrame:cellRectangle]; [dragger setImage:tmpImage]; [dragger setUserInteractionEnabled:YES]; dragger.layer.anchorPoint = CGPointMake(.5,.5); [self.view addSubview:dragger]; I am open to new/cleaner/more correct ways of doing this too.
