  • AS3: Removing EventListeners without knowing amount or names

    - by DevEight
    Hello! First shortly about how my site works: When a link is clicked it checks if something is already displayed in either the Left or Right side of the screen (the website looks like a book, so I have a left page I want to display information on and a right page). If there is already something showing it hides it and displays the new object, together with this it enables all the buttons within that object (I have separate functions to set up each object). An example of such an EventListener would be: pathTo.Button1.addEventListener(MouseEvent.CLICK, function():void {showText(side, object)}); What I'm trying to do is to remove all the previous set EventListeners without having to create separate functions for removing the links inside every object as well. Shorter version: How do I remove all EventListeners on all objects inside another object? The only variable I want to store is the object containing everything. There are however not always EventListeners within the objects.

  • WPF TextBlock Overflow Text to the Left

    - by shf301
    As background I have a very long ID that too long to display in the given area of the TextBlock. The interesting portion of the ID is the end, that is the rightmost portion. What I would like to do is have the TextBlock, rather than the text overflowing right and cutting off the rightmost portion, overflow left and cutoff the leftmost portion. That is given the ID 123456 and a TextBlock with enough space to hold four characters, to get the TextBlock to display 3456 rather than 1234 as it does by default. I could manually trim my ID for display, but given a variable spaced font that's not ideal. So is there someway to get WPF do change the overflow direction?

  • "_FILE_AND_LINE_ is not defined in this scope" (compiling RakNet NAT examples in OS X)

    - by Michael F
    Hello! I'm working on a RakNet-based project (using 3.8 on OS X 10.6), and I'm trying to work through the various examples that demonstrate the parts of RakNet I want to use. For the "NatCompleteClient" example, I've imported the source into a command-line project in XCode, along with the UPNP dependency. At compile time I've had a few errors in the UPNP section, though, and I can't find any guidance on this. In UPNPPortForwarder.mm, there are 7 lines that use _FILE_AND_LINE_, and the compiler is not happy; for example on line 232: foundInterfaces.Deallocate(r1,_FILE_AND_LINE_); causes: UPNPPortForwarder.mm:232: error: '_FILE_AND_LINE_' was not declared in this scope Can anyone tell me what this is all about? That variable doesn't seem to get talked about very often... or Google doesn't like to find it.

  • Why does DestroyWindow close my application?

    - by user146780
    I'v created a window after creating my main one but calling DestroyWindow on its handle closes the entire application, how can I simply get rid of it? it looks like this: BOOL InitInstance(HINSTANCE hInstance, int nCmdShow) { HWND hWnd; HWND fakehandle; hInst = hInstance; // Store instance handle in our global variable hWnd = CreateWindow(szWindowClass, szTitle, WS_OVERLAPPEDWINDOW | WS_EX_LAYERED, CW_USEDEFAULT, 0, CW_USEDEFAULT, 0, NULL, NULL, hInstance, NULL); fakehandle = CreateWindow(szWindowClass, "FAKE WINDOW", WS_OVERLAPPEDWINDOW, CW_USEDEFAULT, 0, CW_USEDEFAULT, 0, NULL, NULL, hInstance, NULL); if (!hWnd || !fakehandle) { return FALSE; } //some code DestroyWindow(fakehandle); ShowWindow(hWnd, nCmdShow); UpdateWindow(hWnd); return TRUE; } how can I destroy this window without destroying my main one? I'm creating a dummy window to check for multisampling in OpenGL. Thanks

  • Is there a reasonable way to attach new path to PATH in bashrc?

    - by Ripley
    Guys I constantly need to attach new paths to the PATH environment variable in .bashrc, like below: export PATH=/usr/local/bin:$PATH Then to make it take effect, I always do 'source ~/.bashrc' or '. ~/.bashrc', while I found one shortcoming of doing so which make me uncomfortable. If I keep doing so, the PATH will getting longer and longer with many duplicated entries, for example in the previous command, if I source it twice, the value of PATH will be PATH=/usr/local/bin:/usr/local/bin:/usr/local/bin:$PATH(<-the original path). Is there a more decent way to attach new path to PATH in bashrc without making it ugly?

  • Eval IronPython Scripts during ASP.NET Web Request; Static Engine or Not

    - by Josh Pearce
    I would like to create an ASP.NET MVC web application which has extensible logic that does not require a re-build. I was thinking of creating a filter which had an instance of the IronPython engine. What I would like to know is: how much overhead is there in creating a new engine during each web request, and would it be a better idea to keep a static engine around? However, if I were to keep a single static engine around, what are the issues I might run into as far as locking and script scope? Is it possible to have multiple scopes in the same IropPython engine so I don't get variable collision and security issues between web requests?

  • JQUERY, div with a fixed height (with a scrollbar) how to animate until it grows to no longer need a

    - by nobosh
    JQUERY, div with a fixed height (with a scrollbar) how to animate until it grows to no longer need a scroll bar? I have a div on a page with a CSS height:200px setting, which makes the DIV have a vertical scroll bar, which allows the user to scroll through a bunch of text. I would like to animate the DIV to expand in height until all content in the div is shown, meaning no more scroll bar I tried the following: $("#view-container").animate({"height": "auto"}, "slow"); but that didn't work while this does: $("#view-container").animate({"height": "1000px"}, "slow"); problem with that is the text size in the DIV is variable. Ideas? Thanks

  • Form Security (discussion)

    - by Eray Alakese
    I'm asking for brain storming and sharing experience. Which method you are using for form submiting security ? For example , for block automatically sended POST or GET datas, i'm using this method : // Generating random string <?php $hidden = substr(md5(microtime()) ,"-5"); ?> <form action="post.php" .... // assing this random string to a hidden input <input type="hidden" value="<?php echo $hidden;" name="secCode> // and then put this random string to a session variable $_SESSION["secCode"] = $hidden; **post.php** if ($_POST["secCode"] != $_SESSION["secCode"]) { die("You have to send this form, on our web site"); }

  • Rails 3 render :partials

    - by user297221
    Hi guys. I am migrating my 1.8.7 rails app to rails 3. But I have a problem with a partial: I have the following partial: in my cms controller : @clients = Client.all group = render_to_string :layout = 'layouts/window', :partial = 'clients/index' in my "clients/index" partial: <%= render :partial = 'clients/item', :collection = @clients % This worked great with rails 1.7.8 but with rails 3 only the partial in the index get's rendered!. So, to clarify this, the group variable in the controller doesn't get the html from the layout. Also the weird thing is that the window layout is _window.erb (if I do window.html.erb or just window.erb rails can't find it which is strange). Does anybody know if this behavior is normal for rails 3? thanxs!

  • Either .each do or .all isn't working how I think it should

    - by user1299656
    So whenever someone rates a shop, I want the Shop model to calculate its new average rating and store that in the database (instead of calculating the average every time someone looks at it). So I wrote the segment of code that follows, and it doesn't work. The loop always iterates exactly once, no matter how many shop_ratings in the database exist that have the shop's id as their shop_id. I played around with it a bit and found that every time a new rating is submitted the function is called successfully, but it only runs the loop once and sets the average to what the first rating was. I don't know if the "query" that sets the ratings variable is wrong or if it's the loop that's wrong. class Shop < ActiveRecord::Base has_many :shop_ratings attr_accessible :name, :latitude, :longitude validates_presence_of :name validates_presence_of :latitude validates_presence_of :longitude def distance_to(lat, long) return (self.longitude - long) + (self.latitude - lat) end def find_average total = 0 count = 0 ratings = ShopRating.all(:conditions => {:shop_id => id}) ratings.each do |submission| total = total + submission.rating count = count + 1 end update_attribute :average_rating, total/count end end

  • Add span tage to ActionLink title

    - by Simon Holman
    I need to add a span tag to the title of an actionlink to output the following html <li><a href="#" id="topmenu1" accesskey="1" title=""><span>Homepage</span></a></li> I currently have <li><%= Html.ActionLink("Homepage", "Index", "Home", null, new { @id= "topmenu1" , @accesskey = "1", @title = "" } ) %></li> which gives me <li><a accesskey="1" href="/" id="topmenu1" title="">Homepage</a></li> without the span tag around Homepage I cannot use <span>Homepage</span> as the title variable of the actionlink, that doesn't work.

    I have a c# .net web application. I create session variables but when I try to read them after I leave the page that they were created from I can't. Created on page 1 Session["UserName"] = "WhatEver"; Then I do Response.Redirect("~/whatever.aspx"); and try to read to read the session variable in the Page_Load method of the new page string userName = Session["UserName"].ToString(); I receive "Object reference not set to an instance of an object." Why am I receiving this error and what can I do to fix the problem? I would greatly appreciate any help anyone can give me.

  • Powershell Select-Object from array not working

    - by Andrew
    I am trying to seperate values in an array so i can pass them to another function. Am using the select-Object function within a for loop to go through each line and separate the timestamp and value fields. However, it doesn't matter what i do the below code only displays the first select-object variable for each line. The second select-object command doesn't seem to work as my output is a blank line for each of the 6 rows. Any ideas on how to get both values $ReportData = $SystemStats.get_performance_graph_csv_statistics( (,$Query) ) ### Allocate a new encoder and turn the byte array into a string $ASCII = New-Object -TypeName System.Text.ASCIIEncoding $csvdata = $ASCII.GetString($ReportData[0].statistic_data) $csv2 = convertFrom-CSV $csvdata $newarray = $csv2 | Where-Object {$_.utilization -ne "0.0000000000e+00" -and $_.utilization -ne "nan" } for ( $n = 0; $n -lt $newarray.Length; $n++) { $nTime = $newarray[$n] $nUtil = $newarray[$n] $util = $nUtil | select-object Utilization $util $tstamp = $nTime | select-object timestamp $tstamp }

  • C: Pointers to any type?

    - by dragme
    I hear that C isn't so type-safe and I think that I could use that as an advantage for my current project. I'm designing an interpreter with the goal for the VM to be extremely fast, much faster than Ruby and Python, for example. Now I know that premature optimization "is the root of all evil" but this is rather a conceptual problem. I have to use some sort of struct to represent all values in my language (from number over string to list and map) Would the following be possible? struct Value { ValueType type; void* value; } I would store the actual values elsewhere, e.g: a separate array for strings and integers, value* would then point to some member in this table. I would always know the type of the value via the type variable, so there wouldn't be any problems with type errors. Now: Is this even possible in terms of syntax and typing?

  • IIS6 Log time recording problems

    - by Hafthor
    On three separate occasions on two separate servers at nearly the same times, 6.9 hours seemingly went by without any data being written to the IIS logs, but, on closer inspection, it appears that it was all recorded all at once. Here's the facts as I know them: Windows Server 2003 R2 w/ IIS6 Logging using GMT, server local time GMT-7. Application was still operating and I have SQL data to prove that Time gaps appear in log file, not across two # headers appear at gap Load balancer pings every 30 seconds No caching Here's info on a particular case: an entry appears for 2009-09-21 18:09:27 then #headers the next entry is for 2009-09-22 01:21:54, and so are the next 1600 entries in this log file and 370 in the next log file. about half of the ~2000 entries on 2009-09-22 01:21:54 are load balancer pings (est. at 2/min for 6.9hrs = 828 pings) then entries are recorded as normal. I believe that these events may coincide with me deploying an ASP.NET application update into those machines. Here's some relevant content from the logs in question: ex090921.log line 3684 2009-09-21 17:54:40 GET /ping.aspx - 80 404 0 0 3733 122 0 2009-09-21 17:55:11 GET /ping.aspx - 80 404 0 0 3733 122 0 2009-09-21 17:55:42 GET /ping.aspx - 80 404 0 0 3733 122 0 2009-09-21 17:56:13 GET /ping.aspx - 80 404 0 0 3733 122 0 2009-09-21 17:56:45 GET /ping.aspx - 80 404 0 0 3733 122 0 #Software: Microsoft Internet Information Services 6.0 #Version: 1.0 #Date: 2009-09-21 18:04:37 #Fields: date time cs-method cs-uri-stem cs-uri-query s-port sc-status sc-substatus sc-win32-status sc-bytes cs-bytes time-taken 2009-09-22 01:04:06 GET /ping.aspx - 80 404 0 0 3733 122 3078 2009-09-22 01:04:06 GET /ping.aspx - 80 404 0 0 3733 122 109 2009-09-22 01:04:06 GET /ping.aspx - 80 200 0 0 278 122 3828 2009-09-22 01:04:06 GET /ping.aspx - 80 200 0 0 278 122 0 2009-09-22 01:04:06 GET /ping.aspx - 80 200 0 0 278 122 0 ... continues until line 5449 2009-09-22 01:04:06 GET /ping.aspx - 80 200 0 0 277 122 0 <eof> ex090922.log #Software: Microsoft Internet Information Services 6.0 #Version: 1.0 #Date: 2009-09-22 00:00:16 #Fields: date time cs-method cs-uri-stem cs-uri-query s-port sc-status sc-substatus sc-win32-status sc-bytes cs-bytes time-taken 2009-09-22 01:04:06 GET /ping.aspx - 80 200 0 0 277 122 0 2009-09-22 01:04:06 GET /ping.aspx - 80 200 0 0 277 122 0 ... continues until line 367 2009-09-22 01:04:06 GET /ping.aspx - 80 200 0 0 277 122 0 2009-09-22 01:04:30 GET /ping.aspx - 80 200 0 0 277 122 0 ... back to normal behavior Note the seemingly correct date/time written to the #header of the new log file. Also note that /ping.aspx returned 404 then switched to 200 just as the problem started. I rename the "I'm alive page" so the load balancer stops sending requests to the server while I'm working on it. What you see here is me renaming it back so the load balancer will use the server. So, this problem definitely coincides with me re-enabling the server. Any ideas?

  • n*n blocks and polygons

    - by OSaad
    Hi, this is actually meant to be for a function called roipoly in matlab but it can be considered a general case problem. Roipoly is a function which lets u select a polygon over an image, and returns a binary mask where u can use it to get indices of the desired polygon. (It is just a normal polygon after all). My application (K-Nearest Neighbor) requires that i make n*n blocks out of the data i have (the polygon), i.e. If i have a polygon (a road or a piece of land), i want a n*n square moving over it while avoiding intersection with edges and putting those n*n pixels into some variable. This problem would be a lot easier if i had all my shapes in the form of rectangles, but that unfortunately isn't the case. I might have something going diagonal, circular or just irregular.

  • Get current session /process id from inside a mysql query

  • Ruby on Rails when create method fails, render loses local variables

    - by Jimmy
    Hey guys I have a simple create method with some validations and whenever the create method fails due to validation errors it re-renders the 'new' action. The problem is in my new action/view I have a local variable that is established in the action and passed to a partial to render some related information to what the user is creating. Now when my create action fails and I try to re-render the 'new' action I'm getting the always awesome undefined method `cover' for nil:NilClass error. What is the best way to handle re-establishing my action's local variables on a render instead of redirecting to the action again and the user losing the data they input?

  • I'm having a problem identifying a floating point exception.

    - by Peter Stewart
    I'm using c++ in visual studio express to generate random expression trees for use in a genetic algorithm type of program. Because they are random, the trees often generate (I'll call them exceptions, I'm not sure what they are) Thanks to a suggestion by George, I turned the mask _MCW_EM on so that hardware interrupts are turned off. (the default) So, the program runs uninterrupted, but some of the values returned are: -1.#INF, -1.#NAN, -1.#INV. I don't know how to identify these so that I can throw an exeption: if ( variable == -1.#INF) ?? DigitalRoss in this post seemed to have the solution, but as I understood it I couldn't make it work. I've been looking all over the place for this simple bit of code, that I assumed would be used all the time, but have had no luck. thanks

  • defining information out of class

    is there a way to define a value within a class in the __init__ part, send it to some variable outside of the class without calling another function within the class? like class c: def __init__(self, a): self.a = a b = 4 # do something like this so that outside of class c, # b is set to 4 automatically when i use class c def function(self): ... # whatever. this doesnt matter i have multiple classes that have different values for b. i could just make a list that tells the computer to change b, but i would rather set b within each class

  • How to create a new IDA project based on an existing one with different offsets?

    - by tbergelt
    I have an existing IDA Pro project for a C166 processor embedded application. This project already has many functions, variables, etc defined. There are different versions of the embedded application I am looking at. The different versions of the application are 99% the same, but with slight variations in code and data that cause functions and variables to be at different memory offsets. I want to create a new IDA project for a different version of the application. I would like to somehow import all of my function and variable definitions from my existing IDA project. I would like IDA to recognize the signatures of the existing function definitions and define them at there new location in the new project. How can I do this? Are there certain plugins for IDA I can chain together?

  • erlang io:format, and a hanging web application

    - by williamstw
    While I'm learning a new language, I'll typically put lots of silly println's to see what values are where at specific times. It usually suffices because the languages typically have available a tostring equivalent. In trying that same approach with erlang, my webapp just "hangs" when there's a value attempted to be printed that's not a list. This happens when variable being printed is a tuple instead of a list. There's no error, exception, nothing... just doesn't respond. Now, I'm muddling through by being careful about what I'm writing out and as I learn more, things are getting better. But I wonder, is there a way to more reliably to [blindly] print a value to stdout? Thanks, --tim
