• How to get new logs in an EventLogEntyCollection?

  - by Massimo

  I need to monitor security event logs on very busy domain controllers, which generates hundreds of them each minute. I know how to use EventLog, EventLogEntry and EvenLogEntryCollection to open and read a server's event log, but an EvenLogEntryCollection can contain ~300.000 events, and it wraps around continuously (and very fast), so I can't rely on its index to find new entries. So far, the only thing I was able to come up with is saving the timestamp of the last processed log entry and then iterate above the EventLogEntryCollection until I find an EventLogEntry which TimeGenerated properties is greater than the timestamp I saved; but it's terribly slow to iterate on ~300.000 entries to find the new ones. How can I quickly find the new entries in an big event log?

• None of my Win Forms buttons work

  - by nectarines

  I have a windows form which connects to a SQL Server though a dataset. The form was working fine since my last compile. All of a sudden, none of my buttons work! The data is loaded on the form, all the tabs work fine, drop down boxes work fine, but the buttons are literally unresponsive to any clicks. I added a test button and I get the same results. I can visually see the button getting clicked but no events. Any ideas?

• PHP Inotify Non-blocking way

  - by demic0de

  I am reading a file in linux which is a log file that keeps on updating weather the file has changed and output it to the webpage. i do it using php inotify but my problem is that it is blocking. How can i make php inotify non-blocking so i can do other stuff while it is monitoring the text file?. <?php $fd = inotify_init(); $watch_descriptor = inotify_add_watch($fd, '/tmp/temp.txt', IN_MODIFY); touch('/tmp/temp.txt'); $events = inotify_read($fd); $contents = file_get_contents('/tmp/temp.txt'); echo $contents; inotify_rm_watch($fd, $watch_descriptor); fclose($fd) ?> Or can i do this in java?..Thanks.

• How to move iframe along the DOM without losing it's content?

  - by Beck

  Is it possible? I have tried to move it, but iframe contents dissapear. Tried to get contents of iframe and place them in the new place but all handlers ofc dissapear. Tried to do the same, but with new jQuery 1.4.2 feature, that clones all events along with it. But it doesn't work :) So I have decided to ask here for help. How to move the damn iframe to another place in the document without losing it's contents? ^_^ Thanks Added: txtad_iframe = ad_container.find('iframe'); its_contents = txtad_iframe.contents(); its_body = its_contents.find("div:first").clone(true).insertAfter(cthis.find('#photos')); new_ad.append(its_body); Here i'm trying to copy contents to new ad container. But it doesn't work. Context banner doesn't react on click event. I have tried to move ad_container to container, but iframe body content dissapears.

• C++ DLL which can inform a calling program about its progress

  - by Felix Dombek

  My boss wants me to write a DLL in C++ (MSVC++2010) which can perform a Volume Shadow Copy which he can call from VB6 (or at a later point other languages) and which can give status updates back while it is not finished. He calls it "events". I have the feeling that I finally need to learn COM (I'd rather not ...) ... also, a callback function comes to my mind, but it's surely impossible to hand over function pointers from VB6 to C++? Can someone outline what I have to learn and how this can be accomplished, with or without COM?

• refactor this javascript code

  - by nathanvda

  I have two click-events, that are nearly similar, but not quite. I am wondering how to refactor them best: $('.remove_fields.dynamic').live('click', function(e) { var $this = $(this); var after_removal_trigger_node = $this.closest(".nested-fields").parent(); trigger_removal_callback($this); e.preventDefault(); $this.closest(".nested-fields").remove(); trigger_after_removal_callback(after_removal_trigger_node); }); $('.remove_fields.existing').live('click', function(e) { var $this = $(this); var after_removal_trigger_node = $this.closest(".nested-fields").parent(); trigger_removal_callback($this); e.preventDefault(); $this.prev("input[type=hidden]").val("1"); $this.closest(".nested-fields").hide(); trigger_after_removal_callback(after_removal_trigger_node); }); As you can tell there is a fair bit of overlap. I am wondering what the best/nicest way would be to refactor this code.

• How do I declare a C# Web User Control but stop it from initializing?

  - by Scott Stafford

  I have a C#/ASP.NET .aspx page that declares two controls that each represents the content of one tab. I want a query string argument (e.g., ?tab=1) to determine which of the two controls is activated. My problem is, they both go through the initialization events and populate their child controls, wasting CPU resources and slowing the response time. Is it possible to deactivate them somehow so they don't go through any initialization? My .aspx page looks like this: <% if (TabId == 0) { %> <my:usercontroltabone id="ctrl1" runat="server" /> <% } else if (TabId == 1) { %> <my:usercontroltabtwo id="ctrl2" runat="server" /> <% } %> And that part works fine. I assumed the that <%'s would have meant the control wouldn't actually be declared and so wouldn't initialize, but that isn't so...

• WF - Creating a selective list

  - by Michael Bendtsen

  I have a stupid question. I have created a workflow Designer host where I publish my own activities. I also have a property grid which only displays the properties decorated with a special attribute. This designer is going to be used by none IT staff. What I want is that on an activity the user can select a property value from a list. I know I just could create an Enum but I would like it to be dynamic. I.e. all events on a specific interface (extracted using reflection). Is this at all possible or am I stuck with enums?

• connecting to multiple resources

  - by Dudu

  I would like to know if there is a way to connect to multiple resources: Specifically I have the following problem abstact class BaseClass { ObservableCollection<BaseClass>; } class GrandSonClass:BaseClass{} class SonClass:BaseClass{} class FatherClass:BaseClass { CollectionViewSource col = new CollectionViewSource ; col.Source = Items.SelectMany(p => p.Items); } FatherClass's Items are of ChildrenClass type, and ChildrenClass's Items are of GrandSonClass type; I want FatherClass to bind to all the GrandSonClass's items it possesses. The solution of using SelectMany is not good as I need this to be dynamically updated whenever FatherClass adds more Items and whenever its Items(SonClasses) add more Items. Now I could go on and write notifiaction events but I was wondering if there is a smarter way to do it -i.e. simply define the sources as the Items of each Item FatherClass posses

• Highlighting current and previous stars on mouseover

  - by mpet

  I'm trying to make simple five star rating system using Twitter Bootstrap 3 i jQuery. For now, I'm trying to set .hover() and .mouseout() events using counter by writing this code that doesn't work: var i; for (i = 1; i <= 5; i++) { $('#overall_rating_' + i).hover(function(){ $('#overall_rating_' + i).removeClass("glyphicon-star-empty").addClass("glyphicon-star"); }); $('#overall_rating_' + i).mouseout(function(){ $('#overall_rating_' + i).removeClass("glyphicon-star").addClass("glyphicon-star-empty"); }); } Trying to highlight current and previous stars on mouseover. The code is not complete, it would be accompanied by additional sub-counters, but this part doesn't work for now. Any better methods are welcome. What's broken here?

• Hibernate - Persisting polymorphic joins

  - by Marty Pitt

  Hi I'm trying to understand how to best implement a polymorphic one-to-many in hibernate. Eg: @MappedSuperclass public class BaseEntity { Integer id; // etc... } @Entity public class Author extends BaseEntity {} @Entity public class Post extends BaseEntity {} @Entity public class Comment extends BaseEntity {} And now, I'd like to also persist audit information, with the following class: @Entity public class AuditEvent { @ManyToOne // ? BaseEntity entity; } What is the appropriate mapping for auditEvent.entity? Also, how will Hibernate actually persist this? Would a series of join tables be generated (AuditEvent_Author , AuditEvent_Post, AuditEvent_Comment), or is there a better way? Note, I'd rather not have my other entity classes expose the other side of the join (eg., List<AuditEvent> events on BaseEntity) - but if that's the cleanest way to implement, then it will suffice.

• Having a UITextField in a UITableViewCell

  - by Mathieu

  Hi! I'm trying to do that for a couple of days now, and after reading tons of messages of people trying to do that too, I'm still unable to have a fully working UITextField in some of my UITableViewCells, just like in this example: http://img231.imageshack.us/img231/4858/picture4za3.png Either I have the form working but the text is not visible (although I set its color to blue), the keyboard goes on the field when I click on it and I haven't been able to correctly implement the keyboard events. I tried with a bunch of examples from Apple (mainly UICatalog, where there is a kinda similar control) but it's still not working correctly. Can somebody help me (and all the people trying to realize this control) and post a simple implementation of a UITextField in a UITableViewCell, that works fine? Thank you very much.

• Event(s) for opening the workbook AND worksheets

  - by KeyMs92

  I'm looking for an elegant solution to trigger an event for opening the workbook as well as opening different worksheets. I don't need seperate operations for each worksheet: they all trigger the same method. I know I can use the events Workbook_Activate / Workbook_Open and Workbook_SheetActivate at the same time but I don't know if this is 'the official way' to do it. Perhaps there's a way to do this with one event. I was also wondering if it is relevant in this matter where I put the code. I now have all the code inside "ThisWorkbook" and not in a "Module"...

• Best way to notify several java applets/applications of a change on a server

  - by Dustin

  I need to know the best (fastest) way to have a server (preferably a php based one, but a jsp/servlet one could be set up as well using google app engine) notify several java applets/applications that a change has occurred to the data. The way i am picturing this to work will be very similar to that of the way i think an online java game (like Runescape) works User 1: Changes data on server. Server: returns success to User 1, notifies connected computers of change. Connected Computer 1: processes change, returns success to server. Connected Computer 2: processes change, returns success to server. Connected Computer 3: processes change, returns success to server. Connected Computer 4: processes change, returns success to server. I am hoping to have this entire process complete in half a second, and not involve polling as there will be long durations of nothing, followed by a sudden moment where 4 events happen in succession.

• Why and How to avoid Event Handler memory leaks ?

  - by gillyb

  Hey There, I just came to realize, by reading some questions and answers on StackOverflow, that adding event handlers using += in C# (or i guess, other .net languages) can cause common memory leaks... I have used event handlers like this in the past many times, and never realized that they can cause, or have caused, memory leaks in my applications. How does this work (meaning, why does this actually cause a memory leak) ? How can I fix this problem ? Is using -= to the same event handler enough ? Are there common design patterns or best practices for handling situations like this ? Example : How am I supposed to handle an application that has many different threads, using many different event handlers to raise several events on the UI ? Are there any good and simple ways to monitor this efficiently in an already built big application ? Thanks in advance!

• UITableView cell selection disabled and UITableViewHeader Enabled

  - by andyPaul

  I am adding a my header view to self.tableView.tableHeaderView=headerView; This tableView has 10 cells. I want to disable the cell Selection but, headerView touch events must be enabled. To achieve this I added the following code: self.tableView.userInteractionDisabled=YES; self.headerView.userInteractionDisabled=NO; self.headerView.exclusiveTouch=YES; Where I am wrong? Basic idea of implementation is , If headerView is enabled then cell selection is disabled and vice-versa.

• OnShutdown() not working on XP

  - by Daro

  I have a service registered for shutdown events (.Net 3.5): public ServiceName() { InitializeComponent(); base.CanHandleSessionChangeEvent = true; base.CanHandlePowerEvent = true; base.CanShutdown = true; } protected override void OnShutdown() { try { if (Program.Debug2Eventlog == true) { WriteEventEntry( "Computer is shutting down.", EventLogEntryType.Information, 0, 3); } } catch {} base.OnShutdown(); } Windows 7 logs the event just fine, but XP doesn't. Am I missing something?

• Are there any well-known algorithms or computer models that computer scientists use to predict FIFA

  - by Khnle

  Occasionally I read news articles that mention about some computer models that computer scientists use to predict winners of some sporting events or the odds for betting which I think there must be a mathematical model behind it. I never bothered to think twice even though I am a "pseudo computer scientist" myself. With the 2010 FIFA World Cup just underway, and since I am also a "pseudo football/soccer player" myself, I just started to wonder about these calculations algorithms. For example, I know one factor is determining the strength of opponents, so that a win against a strong opponent can count more than a win against a weak opponent. But it now kind of gets in a circular loop, or at least how does one determine the strength of a team in the first place, before that team can be considered strong or weak? If it's based on a historical data then there's no way that could be accurate, because those players of the past are no longer on the fields so their impact is none (except maybe if they become coaches like Maradona) Anyway, long question short, if you're happen to be working in this field or have some knowledge, please shed some lights.

• How to clone a model's attributes easily?

  - by Zabba

  I have these models: class Address < ActiveRecord::Base belongs_to :event attr_accessible :street, :city validates :street, :city, :presence => true end class Event < ActiveRecord::Base has_one :address accepts_nested_attributes_for :address end If I do the below assignment in the Events create action and save the event I get an error: #Use the current user's address for the event @event.address_attributes = current_user.address.attributes #Error occurs at the above mentioned line ActiveRecord::RecordNotFound (Couldn't find Address with ID=1 for Event with ID=) I think what's happening is that all the address's attributes (including the primary key) is getting assigned in the @event.address_attributes = line. But all I really want is the "real data" (street, city), not the primary keys or created_at etc to get copied over. I suppose I could write a small method to do this sort of selective copy but I can't help but feel there must be some built-in method for this? What's the best/right way to do this?

• Sharepoint 2010 Calendar Event Receiver

  - by user521682

  I have been tasked with creating a calendar in a root site that get's updated from child site calendar events. I am able to access the Calendar List from the parent site in the child site's to add an event. However, I'm having trouble finding a way to create a uniqueIdentifier for the event so that when the child calendar's event is updated or deleted, the parent site calendar get's updated as well. The ListItem ID field appears to be only unique among the site. I did find a UniqueItemId field, but apparantly it's read-only in the SP LIstitem object. Can someone please give me some guidance here? Many thanks!

• Starting Game dev on iPhone:iPad - learning path ??

  - by Tibi

  Hi there, I'm beginning in iPhone/iPad game dev and I'm searching to set up my learning path. The basic features I would like to learn (after the basic SDK iphone components programming) are : using a board like interface where I can move pawn with my fingers detect where the pawn was moved and triggers events in the game The board will be constitute by 6 tiles that may be organised randomly when starting the game : may i use an sdk component with a delegate and datasource to determine where the pawn was left and on which tile ? need to use dices (which kind of library may I use ?) ... Do you have any idea about where to start ? ;-) Many thanks, Tib.

• Android: Scrollable (bitmap) screen

  - by somin

  I am currently implementing a view in Android that involves using a larger than the screen size bitmap as a background and then having drawables drawn ontop of this. This is so as to simulate a "map" that can be scrolled horizontally aswell as vertically. Which is done by using a canvas and then drawing to this the full "map" bitmap, then putting the other images on top as an overlay and then drawing only the viewable bit of this to screen. Overriding the touch events to redraw the screen on a scroll/fling. I'm sure this probably has a huge ammount of overhead (by creating a canvas of the full image whilst using(drawing) only a fifth of it) and could be done in a different way as to the explained, but I was just wondering what people would do in this situation, and perhaps examples? If you need more info just let me know, Thanks, Simon

• C# Dataset usage necessary before passing to GridView datasource?

  - by Goober

  Scenario Lets say for example I have a series of events that fire continually every half second presenting me with an object containing some bits of information. There are always between 10 and 15 objects that are being updated constantly. Since these bits of information are changing continually I want to display them in a GridView. When I do so, I want the user to see the data displayed in the gridview and actually be updated as opposed to just a continually extending list being printed and incrementing (like writeline on the console). Question Is the best way to achieve this to map my objects to a dataset and have the dataset mapped to the gridview? Thoughts Will this allow the gridview to just be "UPDATED" as opposed to being added to? Any implementation suggestions would be greatly appreciated. EDIT: it MUST be windows forms (I use DevExpress too)

• "Volkswagen Passat" Navigation

  - by joe_midi

  http://web.vw.com/all-new-passat-experience/ The navigation on this .swf is very impressive, and I was wondering how I would go about replicating it. The way each of the sections Design / Technology / Safety / Performance I want to know how each section can expand and still fit together. I've started with MOUSE_OVER events, but I'm not entirely sure how to order them so each section is the right size for every mouse over Event. This is the code I have for each "Section", I have created a movie clip with a Mask that expands on mouse over and brings the selected clip to the highest depth. this.firstButton01.addEventListener(MouseEvent.MOUSE_OVER, firstButton01OVER) function firstButton01OVER(e:Event):void { this.firstButton01.gotoAndPlay(2); this.setChildIndex(firstButton01,this.numChildren-1); }
