  • flash as3, Error #1009

    - by smerels
    I'm making a website that exist out of linked pages. All the pages are on the time line and all the code is in an as3 file. The first page with links works but if I want to place a link on the second frame I get the 1009 error Cannot access a property or method of a null object reference. Because the link doesn't exist on the first frame. This is my code. package { import flash.display.MovieClip; import flash.events.MouseEvent; public class Honger extends MovieClip { public function Honger():void { weten.buttonMode = true; weten.addEventListener(MouseEvent.CLICK, onClickWeten); spelen.buttonMode = true; spelen.addEventListener(MouseEvent.CLICK, onClickSpelen); antwoorden.buttonMode = true; antwoorden.addEventListener(MouseEvent.CLICK, onClickAntwoorden); } public function onClickWeten(e:MouseEvent):void { this.gotoAndStop("vragen"); } public function onClickSpelen(e:MouseEvent):void{ this.gotoAndStop("spel"); } public function onClickAntwoorden(e:MouseEvent):void{ this.gotoAndStop("sp"); } } } Does anyone know how to solve this problem within the code?

  • How do I get ASP.NET login status controls to display a Log In option?

    - by Greg McNulty
    I have the following log in status controls on the top of my master page. It displays the logged in as, manager log in, and Log out options. However, when a user is not logged in, there is nothing displayed there. When the user is NOT logged in, is there a way to display a "Login" text link that takes you to the log in page and then "disappears" once the user is logged in? Any help is appreciated. Thanks! <asp:LoginName ID="LoginName1" runat="server" FormatString="Logged in as {0}" ForeColor="Aqua" /> <asp:LoginView ID="LoginView1" runat="server"> <RoleGroups> <asp:RoleGroup Roles="Managers"> <ContentTemplate> <asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl="~/Management/management.aspx">Manage Site</asp:HyperLink> or <asp:LoginStatus id="LoginStatus1" runat="server" /> </ContentTemplate> </asp:RoleGroup> </RoleGroups> <LoggedInTemplate> (<asp:LoginStatus id="LoginStatus1" runat="server" />) </LoggedInTemplate> </asp:LoginView> ASP.NET 3.5 VWD 2008 C#

  • bat file using winrar taking too long to run

    - by Jessie
    hi guys, i have this scripts which extracts all my folder's and files from my c:\projects locations and put its in winrar and transfers them to c:\backup\project for /f "delims==" %%D in ('DIR C:\projects /A /B /S') do ( "C:\Program Files\WinRAR\WinRAR.EXE" m -r "c:\backup\projects.rar" "%%D" ) i have also tried the below script which uses the same source c:\projects but put them in their own separate winrar folder like in the source then transfers the folders into my c:\backup. FOR /F "DELIMS==" %%D in ('DIR C:\projects /AD /B') DO ( "C:\Program Files\WinRAR\WinRAR.EXE" m -r "C:\Backup\%%D.rar" "%%D" ) my question is, my second scripts only takes two hours to run when my first script takes over 24 hours to run, is there any way to make my first script faster? if anything shouldn't my first script be faster?

  • How do you return a pointer to a base class with a virtual function?

    - by Nick Sweet
    I have a base class called Element, a derived class called Vector, and I'm trying to redefine two virtual functions from Element in Vector. //element.h template <class T> class Element { public: Element(); virtual Element& plus(const Element&); virtual Element& minus(const Element&); }; and in another file //Vector.h #include "Element.h" template <class T> class Vector: public Element<T> { T x, y, z; public: //constructors Vector(); Vector(const T& x, const T& y = 0, const T& z =0); Vector(const Vector& u); ... //operations Element<T>& plus(const Element<T>& v) const; Element<T>& minus(const Element<T>& v) const; ... }; //sum template <class T> Element<T>& Vector<T>::plus(const Element<T>& v) const { Element<T>* ret = new Vector((x + v.x), (y + v.y), (z + v.z)); return *ret; } //difference template <class T> Element<T>& Vector<T>::minus(const Element<T>& v) const { Vector<T>* ret = new Vector((x - v.x), (y - v.y), (z - v.z)); return *ret; } but I always get error: 'const class Element' has no member named 'getx' So, can I define my virtual functions to take Vector& as an argument instead, or is there a way for me to access the data members of Vector through a pointer to Element? I'm still fairly new to inheritance polymorphism, fyi.

  • Overriding Ruby's spaceship operator <=>

    - by ericsteen1
    I am trying to override Ruby's <= (spaceship) operator to sort apples and oranges so that apples come first sorted by weight, and oranges second, sorted by sweetness. Like so: module Fruity attr_accessor :weight, :sweetness def <=>(other) # use Array#<=> to compare the attributes [self.weight, self.sweetness] <=> [other.weight, other.sweetness] end include Comparable end class Apple include Fruity def initialize(w) self.weight = w end end class Orange include Fruity def initialize(s) self.sweetness = s end end fruits = [Apple.new(2),Orange.new(4),Apple.new(6),Orange.new(9),Apple.new(1),Orange.new(22)] p fruits #should work? p fruits.sort But this does not work, can someone tell what I am doing wrong here, or a better way to do this?

  • How to force a line break in a loooooong word in a DIV?

    - by George Edison
    Okay, this is really confusing me. I have some content inside of a div like so: <div style="background-color: green; width: 200px; height: 300px;"> Thisisatest.Thisisatest.Thisisatest.Thisisatest.Thisisatest.Thisisatest. </div> However, the content overflows the DIV (as expected) because the 'word' is too long. How can I force the browser to 'break' the word where necessary to fit all of the content inside?

  • Understanding asp.net mvc IView and IView.Render

    - by Harpreet
    I'm trying to devise a method of doing VERY simple asp.net mvc plugins but mostly I'm trying to understand how view rendering works. I've distilled my problem down to this public class CustomView : IView { public void Render(ViewContext viewContext, TextWriter writer) { writer.Write( /* string to render */); } } Now, within that write method I can render any string to the view but when I put a line of code in there wrapped with <% % it renders the code to the view literally rather than parsing it and executing it. I've tried adding things like <% @Page ... to the beginning of the string and it just renders that literally as well. Among many attempts I'm currently calling it this way within a controller action: ... CustomView customView = new CustomView(); ViewResult result = new ViewResult(); result.View = customView; result.ViewName = "Index.aspx"; result.MasterName = ""; return result; What am I missing or doing wrong that this won't work? The ViewResult seems to have the WebFormViewEngine in its ViewEngines collection. I just want to understand this and after stripping it down to what I think should be the minimum it doesn't behave as I think it should. I'm guessing some other part of the machinery is involved/missing but I can't figure out what.

  • iPhone Audio Queue Service sample units

    - by pion
    I am looking at Audio Queue Services document specifically on the following code: // Writing an audio queue buffer to disk AudioFileWritePackets ( // 1 pAqData->mAudioFile, // 2 false, // 3 inBuffer->mAudioDataByteSize, // 4 inPacketDesc, // 5 pAqData->mCurrentPacket, // 6 &inNumPackets, // 7 inBuffer->mAudioData // 8 ); inBuffer-mAudioDataByteSize is the number of bytes of audio data being written. inBuffer-mAudioData is the new audio data to write to the audio file. Assuming the sample rate is 44100. AudioStreamBasicDescription mDataFormat; mDataFormat.mSampleRate = 44100.0f; mDataFormat.mBitsPerChannel = 16; ... NSInteger numberSamples = inBuffer->mAudioDataByteSize / 2; SInt16 *audioSample = (SInt16 *)inBuffer->mAudioData; I use core-plot to plot the above where x axis is number of sample [1 .. numberSamples] and the y axis is audioSample[0] .. audioSample[numberSamples]. I can see the chart in "real-time" where the y axis goes up and down depending the loudness of my voice. Beginner questions: What does the audioSample represent? What am I looking at here? What is the unit of audioSample? What do I need to do if I just want to plot the range between 50 - 100 Hz? Thanks in advance for your help.

  • What's the best way to normalize scores for ranking things?

    - by beagleguy
    hi all, I'm curious how to do normalizing of numbers for a ranking algorithm let's say I want to rank a link based on importance and I have two columns to work with so a table would look like url | comments | views now I want to rank comments higher than views so I would first think to do comments*3 or something to weight it, however if there is a large view number like 40,000 and only 4 comments then the comments weight gets dropped out. So I'm thinking I have to normalize those scores down to a more equal playing field before I can weight them. Any ideas or pointers to how that's usually done? thanks

  • How to implement Horner's scheme for multivariate polynomials?

    - by gsreynolds
    Background I need to solve polynomials in multiple variables using Horner's scheme in Fortran90/95. The main reason for doing this is the increased efficiency and accuracy that occurs when using Horner's scheme to evaluate polynomials. I currently have an implementation of Horner's scheme for univariate/single variable polynomials. However, developing a function to evaluate multivariate polynomials using Horner's scheme is proving to be beyond me. An example bivariate polynomial would be: 12x^2y^2+8x^2y+6xy^2+4xy+2x+2y which would factorised to x(x(y(12y+8))+y(6y+4)+2)+2y and then evaluated for particular values of x & y. Research I've done my research and found a number of papers such as: staff.ustc.edu.cn/~xinmao/ISSAC05/pages/bulletins/articles/147/hornercorrected.pdf citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.40.8637&rep=rep1&type=pdf www.is.titech.ac.jp/~kojima/articles/B-433.pdf Problem However, I'm not a mathematician or computer scientist, so I'm having trouble with the mathematics used to convey the algorithms and ideas. As far as I can tell the basic strategy is to turn a multivariate polynomial into separate univariate polynomials and compute it that way. Can anyone help me? If anyone could help me turn the algorithms into pseudo-code that I can implement into Fortran myself, I would be very grateful.

  • STL vector performance

    - by iAdam
    STL vector class stores a copy of the object using copy constructor each time I call push_back. Wouldn't it slow down the program? I can have a custom linkedlist kind of class which deals with pointers to objects. Though it would not have some benefits of STL but still should be faster. See this code below: #include <vector> #include <iostream> #include <cstring> using namespace std; class myclass { public: char* text; myclass(const char* val) { text = new char[10]; strcpy(text, val); } myclass(const myclass& v) { cout << "copy\n"; //copy data } }; int main() { vector<myclass> list; myclass m1("first"); myclass m2("second"); cout << "adding first..."; list.push_back(m1); cout << "adding second..."; list.push_back(m2); cout << "returning..."; myclass& ret1 = list.at(0); cout << ret1.text << endl; return 0; } its output comes out as: adding first...copy adding second...copy copy The output shows the copy constructor is called both times when adding and when retrieving the value even then. Does it have any effect on performance esp when we have larger objects?

  • Custom Server to communicate with my software?

    - by Zachary Brown
    I am working on a major project that I need for work. I am working on a project that requires software validation. I would like this to be handled by a custom server I will write in Python, this server will be the "gateway" between the user and product activation. The software program will be purchased from other companies in volume licensing. So this is what I need the server to do: 1). The user clicks to activate their software. (easy, all is good so far) 2). The software gets the distributor's id from another online server. ( this is also easy, and already coded.) 3). Then, the software asks my custom server if the distributor is allowed to activate anymore copies of the software. 4). The server will then check ( an online encoded text file ) to see if the distributor can or can't. If they can, it will tell the software that registration can proceede, at which point the software will pass the software serial number to the server. I have done my best to explain what I am trying to accomplish, but if something is not quite sensible, please let me know. Thanks to all members of Stackoverflow.com for the help in the past, and those who will help me now. I am using Python 2.6 Win. XP Home Edition

  • Java side scrolling game on android

    - by hanesjw
    I'm trying to make an easy side scrolling game just to learn the ropes of game programming on android. I came up with a solution of how to make it but I don't really think it is the most elegant solution. I wanted to get some different ideas on how to implement my game, as I really have no other solution right now. Here is a quick explanation of how it works.. I basically have blocks or objects fall from the top of the screen. The blocks are defined from a pre-defined string I create using a custom 'map-editor'. I create all the blocks at compile time, position them on or off the screen and simply increment their coordinates with each iteration of the gameloop. It is actually done a little bit better then that, but that gives a short easy explanation on the basic idea. I heard from a few people that instead of incrementing each block position, have the blocks stay there and simply change the viewable area. That makes sense, but I have no idea how to do it. Can anyone share some ideas or links on how I can implement something like this? I know my current solution isn't the greatest. Thanks!

  • How to Practically Split Values from CSV File into MySQL Database

    - by Ryan
    Let's suppose I have the following line in a CSV file (I removed the header row in this example): "500,000",2,50,2,90000 I have a PHP script read the CSV file, break the file into individual lines, and store each line in an array called $linearray. Then, I use a foreach loop to look at each line individually. Within the foreach loop, I break the line into separate variables using the following function: $line = str_replace("'","\'",$line); From here, I insert the values into separate columns within a MySQL database. The script works. The values are inserted into a database, but I run into a problem. I want: "500,000" | 2 | 50 | 2 | 90000 But I get this: "500 | 000" | 2 | 50 | 2 | 90000 The script isn't smart enough to understand it should skip commas within quotation marks. Do you know how I can alter my script to make sure I get the output I'm looking for? Thanks.
