  • Stop all sounds permanently in AS3

    - by Fahim Akhter
    Hi, I have a main swf which has sound on/off buttons. It has many SWF's which are loaded into different placeholders at different time. All of them have different sounds in them. In addition to that there is a music loop going on in the background. Now, this perticular swf lets call it Father will be placed in some swf later on. What I'm trying to do right now is when the sound off button is pressed turn off all the sounds permanently so the child swf's and their sounds stop too. I have found a way in AS2 : global = new Sound( ) //no movie clip target path. and add the following code to your off button. on(release){ global.setVolume(0); //mutes all sound } and for on button on(release){ global.setVolume(100); //un mutes all sound } which ofcourse does not work for AS3. So how can I stop all sounds permanently in AS3? Secondly what if I have one sound (my background loop) which I want to keep going on. Would be a lot of help, been searching for a while now without a appropriate answer.

  • installing paramiko

    - by fixxxer
    This may sound like a repeated question on SF, but I could not find a clear answer to it, yet.So. I installed Paramiko 1.7 with "setup.py install" command and while running the demo.py program, I got this error: Traceback (most recent call last): File "C:\Documents and Settings\fixavier\Desktop\paramiko-1.7\demos\demo.py", line 33, in <module> import paramiko File "C:\Python26\lib\site-packages\paramiko\__init__.py", line 69, in <module> from transport import randpool, SecurityOptions, Transport File "C:\Python26\lib\site-packages\paramiko\transport.py", line 32, in <module> from paramiko import util File "C:\Python26\lib\site-packages\paramiko\util.py", line 31, in <module> from paramiko.common import * File "C:\Python26\lib\site-packages\paramiko\common.py", line 99, in <module> from Crypto.Util.randpool import PersistentRandomPool, RandomPool ImportError: No module named Crypto.Util.randpool I'm getting this error even after installing PyCrypto 2.1.

Please advice.Is it the way of installation thats problematic?

  • What scalability problems have you solved using a NoSQL data store?

    - by knorv
    NoSQL refers to non-relational data stores that break with the history of relational databases and ACID guarantees. Popular open source NoSQL data stores include: Cassandra (tabular, written in Java, used by Facebook, Twitter, Digg, Rackspace, Mahalo and Reddit) CouchDB (document, written in Erlang, used by Engine Yard and BBC) Dynomite (key-value, written in C++, used by Powerset) HBase (key-value, written in Java, used by Bing) Hypertable (tabular, written in C++, used by Baidu) Kai (key-value, written in Erlang) MemcacheDB (key-value, written in C, used by Reddit) MongoDB (document, written in C++, used by Sourceforge, Github, Electronic Arts and NY Times) Neo4j (graph, written in Java, used by Swedish Universities) Project Voldemort (key-value, written in Java, used by LinkedIn) Redis (key-value, written in C, used by Engine Yard, Github and Craigslist) Riak (key-value, written in Erlang, used by Comcast and Mochi Media) Ringo (key-value, written in Erlang, used by Nokia) Scalaris (key-value, written in Erlang, used by OnScale) ThruDB (document, written in C++, used by JunkDepot.com) Tokyo Cabinet/Tokyo Tyrant (key-value, written in C, used by Mixi.jp (Japanese social networking site)) I'd like to know about specific problems you - the SO reader - have solved using data stores and what NoSQL data store you used. Questions: What scalability problems have you used NoSQL data stores to solve? What NoSQL data store did you use? What database did you use before switching to a NoSQL data store? I'm looking for first-hand experiences, so please do not answer unless you have that.

  • Dynamic if statement evaluation problem with string comparison

    - by Mani
    I tried the example given in this thread to create if statement dynamically using BeanShell. But it is not working fine. Instead of using "age" variable as integer, i have used string in the below example. I am getting "fail" as answer instead of "success". Can anyone help me? /* To change this template, choose Tools | Templates and open the template in the editor. */ import java.lang.reflect.*; import bsh.Interpreter; public class Main { public static String d; public static void main(String args[]) { try { String age = "30"; String cond = "age==30"; Interpreter i = new Interpreter(); i.set("age", age); System.out.println(" sss" + i.get("age")); if((Boolean)i.eval(cond)) { System.out.println("success"); } else { System.out.println("fail"); } } catch (Throwable e) { System.err.println(e); } } } Thanks, Mani

  • How do I test OpenCL on GPU when logged in remotely on Mac?

    - by Christopher Bruns
    My OpenCL program can find the GPU device when I am logged in at the console, but not when I am logged in remotely with ssh. Further, if I run the program as root in the ssh session, the program can find the GPU. The computer is a Snow Leopard Mac with a GeForce 9400 GPU. If I run the program (see below) from the console or as root, the output is as follows (notice the "GeForce 9400" line): 2 devices found Device #0 name = GeForce 9400 Device #1 name = Intel(R) Core(TM)2 Duo CPU P8700 @ 2.53GHz but if it is just me, over ssh, there is no GeForce 9400 entry: 1 devices found Device #0 name = Intel(R) Core(TM)2 Duo CPU P8700 @ 2.53GHz I would like to test my code on the GPU without having to be root. Is that possible? Simplified GPU finding program below: #include <stdio.h> #include <OpenCL/opencl.h> int main(int argc, char** argv) { char dname[500]; size_t namesize; cl_device_id devices[10]; cl_uint num_devices; int d; clGetDeviceIDs(0, CL_DEVICE_TYPE_ALL, 10, devices, &num_devices); printf("%d devices found\n", num_devices); for (d = 0; d < num_devices; ++d) { clGetDeviceInfo(devices[d], CL_DEVICE_NAME, 500, dname, &namesize); printf("Device #%d name = %s\n", d, dname); } return 0; } EDIT: I found essentially the same question being asked on nvidia's forums. Unfortunately, the only answer was of the form "this is the wrong forum".

  • Problem in IE8 with GET Parameters in opening a new windows with javascript.

    - by amfa95
    Hi, I have a problem with IE8 and the opening of a new window with javascript and submitting parameters with special characters. <a href="javascript:oWin('/html/de/4664286/printregistrationcontent.html?12-security question&#61;Wie hei&#223;t Ihr Lieblingsrestaurant','PRINT',800,600);" class="print">Seite drucken</a> The Problem is the letter 'ß' (sharp S). As you can see the string above is encodes due to anti XSS. This link works in FF and IE6 but IE8 is transmitting the URL Parameter as character with code 65*** (don't know the exaxt value). In the opening window you will only see a square (because character with 65000+ is not printable). I also tried to use URL Encoding instead of HTML encoding <a href="javascript:oWin('/html/de/4664286/printregistrationcontent.html?12-security question%3DWie hei%C3%9Ft Ihr Lieblingsrestaurant','PRINT',800,600);" class="print">Seite drucken</a> If i click on this Link in FF or IE6 it works as expected, but IE8 will fail to transmit the "ß" to the server and therefor will also get it back in the wrong way. If i paste this url to the IE8 it will work too, but not if the window is opened by javascript. The Javascript function oWin is defined as follows function oWin(url,title,sizeH,sizeV) { winHandle = top.open(url,title,'toolbar=no,directories=no,status=yes,scrollbars=yes,menubar=no,resizable=no,width='+sizeH+',height='+sizeV); if(navigator.appVersion.indexOf("MSIE 3",0)==-1) id = setTimeout('winHandle.focus()',1000); } If someone has an idea where to look for the reason please answer to this. Thank you amfa

  • How to group strings by prefix

    - by namenlos
    I am writing a Winform UI in which the user must select a single customer. (For reasons beyond my control I am limited to a UI that uses dropdown lists, text fields, checkboxes, radiobuttons only -i.e. no fancy special UI controls) The situation There are a lot of customers (a thousand for example) If i put all the customers in a single dropdown there's no way it will be easy for a customer to even see all the customers. Also the it will take too long to retireve all the customers from the DB to populate the dropdown My thought is to have two combo box, the first lists groups of the customers by their last name something like a phone book "Aa-Ac", "Ad-Ade", "Adf-B", when selecting the first combo box, it scope the second one to a managable set customer names (no more than for example 40 names) The question I need a reasonable way of grouping their names such that it will be clear to customer which group contains the name. I.e. given a group of names I need to bucketize then int "Aa-Ac". Comments I don't need to solve the general problem of an immense number of names - we know based on our data that 1000 names is the max our users will encounter. If there are other techniques please do share, but I am interested specifically in an answer to my specific question around how to determine the buckets ("Aa-Ac", etc.)

  • Delete array of size 1

    - by Arne
    This is possibly a candidate for a one-line answer. I would like know it anyway.. I am writing a simple circular buffer and for some reasons that are not important for the question I need to implement it using an array of doubles. In fact I have not investiated other ways to do it, but since an array is required anyway I have not spent much time on looking for alternatives. template<typename T> class CircularBuffer { public: CircularBuffer(unsigned int size); ~CircularBuffer(); void Resize(unsigned int new_size); ... private: T* buffer; unsigned int buffer_size; }; Since I need to have the buffer dynamically sized the buffer_size is neither const nor a template parameter. Now the question: During construction and in function Resize(int) I only require the size to be at least one, although a buffer of size one is effectively no longer a buffer. Of course using a simple double instead would be more appropriate but anyway. Now when deleting the internal buffer in the destructor - or in function resize for that matter - I need to delete the allocated memory. Question is, how? First candidate is of course delete[] buffer; but then again, if I have allocated a buffer of size one, that is if the pointer was aquired with buffer = new T[0], is it still appropriate to call delete[] on the pointer or do I need to call delete buffer; (without brackets) ? Thanks, Arne

  • Computer science textbooks

    - by Barrett Conrad
    I would like to try the book question a little bit differently. My goal is to know what the community thinks are the quintessential computer science textbooks. <beginsadstory>I lost all of my computer science and math books from college in Hurricane Katrina in 2005. I greatly miss having my familiar tomes to refer to when topics and problems come up, so I am looking to rebuild my library.<endsadstory> What are your recommendations for the best examples of academic caliber books for the field of computer science and its associated mathematics? I am looking for books on subjects like computational theory, programming languages, compilers, operating systems, algorithms and so on. Don't limit your suggestions to your textbooks only. If there is a book you have read that covers computer science or a related math in a formal way, but is not strictly a textbook, I would be love to hear about them as well. Finally, for the sake of creating a good reference for all of us, may I suggest posting one book per answer so they can be rated individually.

  • Database warehouse design: fact tables and dimension tables

    - by morpheous
    I am building a poor man's data warehouse using a RDBMS. I have identified the key 'attributes' to be recorded as: sex (true/false) demographic classification (A, B, C etc) place of birth date of birth weight (recorded daily): The fact that is being recorded My requirements are to be able to run 'OLAP' queries that allow me to: 'slice and dice' 'drill up/down' the data and generally, be able to view the data from different perspectives After reading up on this topic area, the general consensus seems to be that this is best implemented using dimension tables rather than normalized tables. Assuming that this assertion is true (i.e. the solution is best implemented using fact and dimension tables), I would like to seek some help in the design of these tables. 'Natural' (or obvious) dimensions are: Date dimension Geographical location Which have hierarchical attributes. However, I am struggling with how to model the following fields: sex (true/false) demographic classification (A, B, C etc) The reason I am struggling with these fields is that: They have no obvious hierarchical attributes which will aid aggregation (AFAIA) - which suggest they should be in a fact table They are mostly static or very rarely change - which suggests they should be in a dimension table. Maybe the heuristic I am using above is too crude? I will give some examples on the type of analysis I would like to carryout on the data warehouse - hopefully that will clarify things further. I would like to aggregate and analyze the data by sex and demographic classification - e.g. answer questions like: How does male and female weights compare across different demographic classifications? Which demographic classification (male AND female), show the most increase in weight this quarter. etc. Can anyone clarify whether sex and demographic classification are part of the fact table, or whether they are (as I suspect) dimension tables.? Also assuming they are dimension tables, could someone elaborate on the table structures (i.e. the fields)? The 'obvious' schema: CREATE TABLE sex_type (is_male int); CREATE TABLE demographic_category (id int, name varchar(4)); may not be the correct one.

  • UX question: is better to have "serious delete" or have "trash"

    - by ftrotter
    I am developing an application that allows for a user to manage some individual data points. One of the things that my users will want to do is "delete" but what should that mean? For a web application is it better to present a user with the option to have serious delete or to use a "trash" system? Under "serious delete" (would love to know if there is a better name for this...) you click "delete" and then the user is warned "this is final and tragic action. Once you do this you will not be able to get -insert data point name here- back, even if you are crying..." Then if they click delete... well it truly is gone forever. Under the "trash" model, you never trust that the user really wants to delete... instead you remove the data point from the "main display" and put into a bucket called "the trash". This gets it out of the users way, which is what they usually want, but they can get it back if they make a mistake. Obviously this is the way most operating systems have gone. The advantages of "serious delete" are: Easy to implement Easy to explain to users The disadvantages of "serious delete" are: it can be tragically final sometimes, cats walk on keyboards The advantages of the "trash" system are: user is safe from themselves bulk methods like "delete a bunch at once" make more sense saves support headaches The disadvantages of the "trash" system are": For sensitive data, you create an illusion of destruction users think something is gone, but it is not. Lots of subtle distinctions make implementation more difficult Do you "eventually" delete the contents of the trash? My question is which one is the right design pattern for modern web applications? With enough discussion to justify your answer... Would love to be pointed towards some relevant research. -FT

  • LINQ 2 SQL: Partial Classes

    - by Refracted Paladin
    I need to set the ConnectionString for my DataContext's based on an AppSetting. I am trying to do this by creating a Partial Class for each DataContext. The below is what I have so far and I am wondering if I am overlooking something? Specifically, am I dealing with my DataContext's correctly(disposing, staleness, etc)? Doing it this way will I have issues with Updates and Inserts? Is the file BLLAspnetdb.cs useful or neccessary in the least or should all of that be in the generated partial class AspnetdbDataContext file? In short, is this an acceptable structure or will this cause me issues as I elaborate it? dbml File Name = Aspnetdb.dbml Partial Class File Name = Aspnetdb.cs partial class AspnetdbDataContext { public static bool IsDisconnectedUser { get { return Convert.ToBoolean(ConfigurationManager.AppSettings["IsDisconnectedUser"]) == true; } } public static AspnetdbDataContext New { get { var cs = IsDisconnectedUser ? Settings.Default.Central_aspnetdbConnectionString : Settings.Default.aspnetdbConnectionString; return new AspnetdbDataContext(cs); } } } My Created File Name = BLLAspnetdb.cs public class BLLAspnetdb { public static IList WorkerList(Guid userID) { var DB = AspnetdbDataContext.New; var workers = from user in DB.tblDemographics where user.UserID == userID select new { user.FirstName, user.LastName, user.Phone }; IList theWorkers = workers.ToList(); return theWorkers; } public static String NurseName(Guid? userID) { var DB = AspnetdbDataContext.New; var nurseName = from demographic in DB.tblDemographics where demographic.UserID == userID select demographic.FirstName +" " + demographic.LastName; return nurseName.SingleOrDefault(); } public static String SocialWorkerName(Guid? userID) { var DB = AspnetdbDataContext.New; var swName = from demographic in DB.tblDemographics where demographic.UserID == userID select demographic.FirstName + " " + demographic.LastName; return swName.SingleOrDefault(); } } see this previous question and the accepted answer for background on how I got to here... switch-connectionstrings-between-local-and-remote-with-linq-to-sql

  • javascript using 'this' in global object

    - by Marco Demaio
    What does 'this' keyword refer to when used in gloabl object? Let's say for instance we have: var SomeGlobalObject = { rendered: true, show: function() { /* I should use 'SomeGlobalObject.rendered' below, otherwise it won't work when called from event scope. But it works when called from timer scope!! How can this be? */ if(this.rendered) alert("hello"); } } Now if we call in an inline script in the HTML page: SomeGlobalObject.show(); window.setTimeout("Msg.show()", 1000); everything work ok. But if we do something like AppendEvent(window, 'load', Msg.show); we get an error because this.rendered is undefined when called from the event scope. Do you know why this happens? Could you explain then if there is another smarter way to do this without having to rewrite every time "SomeGlobalObject.someProperty" into the the SomeGlobalObject code? Thanks! AppendEvent is just a simple cross-browser function to append an event, code below, but it does not matter in order to answer the above questions. function AppendEvent(html_element, event_name, event_function) { if(html_element.attachEvent) //IE return html_element.attachEvent("on" + event_name, event_function); else if(html_element.addEventListener) //FF html_element.addEventListener(event_name, event_function, false); }

  • MATLAB intersection of 2 surfaces

    - by caglarozdag
    Hi everyone, I consider myself a beginner in MATLAB so bear with me if the answer to my question is an obvious one. Phi=0:pi/100:2*pi; Theta=0:pi/100:2*pi; [PHI,THETA]=meshgrid(Phi,Theta); R=(1 + cos(PHI).*cos(PHI)).*(1 + cos(THETA).*cos(THETA)); [X,Y,Z]=sph2cart(THETA,PHI,R); surf(X,Y,Z); %display hold on; x1=-4:.1:4; [X1,Y1] = meshgrid(x1); a=1.8; b=0; c=3; d=0; Z1=(d- a * X1 - b * Y1)/c; shading flat; surf(X1,Y1,Z1); I have written this code which plots a 3d cartesian plot of a plane intersecting a peanut shaped object at an angle. I need to get the intersection of these on 2D (going to be the outline of a peanut, but a bit skewed since the intersection happens at an angle), but don't know how. Thanks

  • How can I disable the CTRL-ALT-DEL key combination completely on XP/Vista/7?

    - by Travesty3
    I have been googling extensively to figure this out, and nobody seems to be able to give a direct answer. Let me start by saying that I'm NOT talking about requiring CTRL-ALT-DEL to enter logon information. I'm working on a golf simulator program which is used at golf centers. I need the ability to completely disable the CTRL-ALT-DEL key sequence so that the golf center customers can't get out of the program and access the computer at all. I realize there are other key combinations that need to be handled as well, we already have this entire feature working in XP, but we're going to be switching to Windows 7 soon, and CTRL-ALT-DEL is the only one that doesn't seem to work in Win7. I'd really like an all-around solution if at all possible. This same program may also be installed on a client's personal computer for an in-home golf simulator, but the computers that really need this feature (golf center computers) are provided to the golf center by us, so would the best option be to write a new shell? I don't know anything about that at all, other than others that suggest writing a new shell for kiosk mode. I'd really like a simpler option, like modifying the registry in some way. I have heard that you can remove some buttons from the menu screen that pops up, but unless I can remove pretty much all of them (including the shutdown/restart button in the bottom-right corner), this won't be enough of a solution for me. Thanks for taking the time to read this and thanks again for any help you could provide! -Travis

  • jquery click on anchor element forces scroll to top?

    - by Dan.StackOverflow
    http://stackoverflow.com/questions/720970/jquery-hyperlinks-href-value[link text][1] I am running in to a problem using jquery and a click event attached to an anchor element. [1]: http://stackoverflow.com/questions/720970/jquery-hyperlinks-href-value "This" SO question seems to be a duplicate, and the accepted answer doesn't seem to solve the problem. Sorry if this is bad SO etiquette. In my .ready() function I have: jQuery("#id_of_anchor").click(function(event) { //start function when any update link is clicked Function_that_does_ajax(); }); and my anchor looks like this: <a href="#" id="id_of_anchor"> link text </a> but when the link is clicked, the ajax function is performed as desired, but the browser scrolls to the top of the page. not good. I've tried adding: event.preventDefault(); before calling my function that does the ajax, but that doesn't help. What am I missing? Clarification I've used every combination of return false; event.preventDefault(); event.stopPropagation(); before and after my call to my js ajax function. It still scrolls to the top.

  • How to set up a user Quartz2D coordinate system with scaling that avoids fuzzy drawing?

    - by jdmuys
    This topic has been scratched once or twice, but I am still puzzled. And Google was not friendly either. Since Quartz allows for arbitrary coordinate systems using affine transform, I want to be able to draw things such as floorplans using real-life coordinate, e.g. feet. So basically, for the sake of an example, I want to scale the view so that when I draw a 10x10 rectangle (think a 1-inch box for example), I get a 60x60 pixels rectangle. It works, except the rectangle I get is quite fuzzy. Another question here got an answer that explains why. However, I'm not sure I understood that reason why, and moreover, I don't know how to fix it. Here is my code: I set my coordinate system in my awakeFromNib custom view method: - (void) awakeFromNib { CGAffineTransform scale = CGAffineTransformMakeScale(6.0, 6.0); self.transform = scale; } And here is my draw routine: - (void)drawRect:(CGRect)rect { CGContextRef context = UIGraphicsGetCurrentContext(); CGRect r = CGRectMake(10., 10., 11., 11.); CGFloat lineWidth = 1.0; CGContextStrokeRectWithWidth(context, r, lineWidth); } The square I get is scaled just fine, but totally fuzzy. Playing with lineWidth doesn't help: when lineWidth is set smaller, it gets lighter, but not crisper. So is there a way to set up a view to have a scaled coordinate system, so that I can use my domain coordinates? Or should I go back and implementing scaling in my drawing routines? Note that this issue doesn't occur for translation or rotation. Thanks

  • Why isn't my WPF Datagrid showing data?

    - by Edward Tanguay
    This walkthrough says you can create a WPF datagrid in one line but doesn't give a full example. So I created an example using a generic list and connected it to the WPF datagrid, but it doesn't show any data. What do I need to change on the code below to get it to show data in the datagrid? ANSWER: This code works now: XAML: <Window x:Class="TestDatagrid345.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:toolkit="http://schemas.microsoft.com/wpf/2008/toolkit" xmlns:local="clr-namespace:TestDatagrid345" Title="Window1" Height="300" Width="300" Loaded="Window_Loaded"> <StackPanel> <toolkit:DataGrid ItemsSource="{Binding}"/> </StackPanel> </Window> Code Behind: using System.Collections.Generic; using System.Windows; namespace TestDatagrid345 { public partial class Window1 : Window { private List<Customer> _customers = new List<Customer>(); public List<Customer> Customers { get { return _customers; }} public Window1() { InitializeComponent(); } private void Window_Loaded(object sender, RoutedEventArgs e) { DataContext = Customers; Customers.Add(new Customer { FirstName = "Tom", LastName = "Jones" }); Customers.Add(new Customer { FirstName = "Joe", LastName = "Thompson" }); Customers.Add(new Customer { FirstName = "Jill", LastName = "Smith" }); } } }

  • Creating instance of a service-side DataContract class on client-side in WCF

    - by hgulyan
    Hi, I have my custom class Customer with its properties. I added DataContract mark above the class and DataMember to properties and it was working fine, but I'm calling a service class's function, passing customer instance as parameter and some of my properties get 0 values. While debugging I can see my properties values and after it gets to the function, some properties' values are 0. Why it can be so? There's no code between this two actions. DataContract mark workes fine, everything's ok. Any suggestions on this issue? I tried to change ByRef to ByVal, but it doesn't change anything. Why it would pass other values right and some of integer types just 0? Maybe the answer is simple, but I can't figure it out. Thank You. <DataContract()> Public Class Customer Private Type_of_clientField As Integer = -1 <DataMember(Order:=1)> Public Property type_of_client() As Integer Get Return Type_of_clientField End Get Set(ByVal value As Integer) Type_of_clientField = value End Set End Property End Class <ServiceContract(SessionMode:=SessionMode.Allowed)> <DataContractFormat()> Public Interface CustomerService <OperationContract()> Function addCustomer(ByRef customer As Customer) As Long End Interface type_of_client properties value is 6 before I call addCustomer function. After it enters that function the value is 0. UPDATE: The issue is in instance creating. When I create an instance of a class on client side, that is stored on service side, some of my properties pass 0 or nothing, but when I call a function of a service class, that returns a new instance of that class, it works fine. What's is the difference? Could that be serialization issue?

  • View Controller's viewDidLoad method finishing before applicationDidFinishLaunching

    - by mwt
    I'm creating a fairly complex iPhone app using Core Data. Up until now, things have been working fine. As the app has been getting more complex, however, a new problem has come up: the first view controller is finishing its viewDidLoad method before the AppDelegate gets even halfway through its applicationDidFinishLaunching method. The view controller is not the root, which is a tab bar controller. The VC in question is the one for the default selected tab on the tab bar. It's getting instantiated by IB. Nothing like this has occurred before in my experience, and it's throwing off the important initialization I'm doing in the AppDelegate (getting objects from Core Data and preparing them for use) . Furthermore, it's intermittent -- sometimes the delegate does finish first. Has anyone else noticed a difficulty like this? Any sample code that deals with such an issue? I suppose that the answer is to make the VC load the data that the AppDelegate is getting ready only when the AppDelegate sends a message that it's ready. I'm a bit concerned that this is adding something that will just end up biting me in the butt later on.

  • Is CSS Inheritance in Internet Explorer 8 still buggy?

    - by rrrr
    I have a situation that I am looking at where certain CSS properties will not be inherited. This revolves around tables and IE8. Using the sample HTML below I cannot get the text within the table to inherit the green colour. This works in Firefox and Chrome, but not IE8 and from reading up this seems to have always been a problem in IE but was meant to be working in version 8 from what I read. I have tried to specify the inherit value everywhere possible, but to no avail so the question is whether the CSS inheritance support in IE8 is buggy, or am I missing something? I don't want answer changing inline CSS to be classes and I certainly dont wan't any comments on tables as this all stems from building and designing HTML emails where inline CSS and tables are essential. <html> <head></head> <body> <table style="color: green;"> <tr> <td> <span>Span</span> <p>Paragraph</p> <div>Div</div> <table style="color:inherit;"> <tr> <td>Table</td> </tr> </table> </td> </tr> </table> </body> </html>

  • shortest digest of a string

    - by meta
    [Description] Given a string of char type, find a shortest digest, which is defined as: a shortest sub-string which contains all the characters in the original string. [Example] A = "aaabedacd" B = "bedac" is the answer. [My solution] Define an integer table with 256 elements, which is used to record the occurring times for each kind of character in the current sub-string. Scan the whole string, statistic the total kinds of character in the given string by using the above table. Use two pointers, start, end, which are initially pointing to the start and (start + 1) of the given string. The current kinds of character is 1. Expand sub-string[start, end) at the end until it contains all kinds of character. Update the shortest digest if possible. Contract sub-string[start, end] at the start by one character each time, try to restore its digest property if necessary by step 4. The time cost is O(n), and the extra space cost is constant. Any better solution without extra space?

  • IRC Server configuration possibilities

    - by Katai
    I need to know a couple of things, concerning IRC servers that I couldnt directly find out over google (or werent clear enough for me to be sure if it actually works) I'm working at a larger community site, and wanted to deliver an in-page chat. Since it would be a nice feature to let people access it from outside too, over their own clients, I tought implementing an IRC Server would be the best solution (probably dedicated, I'll have to teach myself a couple of things for that) I plan to include a Web-based IRC client over an APE Client / Server. The problem is, I want to strip down the user rights, to disallow many functionalities that IRC would offer: Change of nicknames: The user logs in over the Page login, and I'll automatically create an IRC auth for this user with that password. So basically, he would connect to the IRC client over a button. And after connecting, he shouldnt be able to change his nickname at all Creating channels: I want the possibility to create channels, but not from 'normal' users. Basically, I would prefer to set up basic channels that are public, and if a user really creates an own channel, that one should be private and via invitation (is that possible?) Private conversations: private conversations should be filtered out from the allaround IRC client, into separate 'in-browser-windows' that I create over JS. I guess I just have to filter the stuff coming from IRC - or is there a better solution to that? Only 'registered' users have access: Like I said, if someone registers on the page, I would like to create an IRC 'account' for him. Users that arent registered on the page, cant access the IRC server at all (or get thrown out). Mainly to avoid spammers or bots from outside. Is this stuff solvable over IRC? I've read some FAQ's and Instructions for IRC OP's and servers, but I couldnt find a clear answer - it seems that everyone can do pretty much everything - I would like to configure it in a way that user possibilities are more cut down. Basically, giving users the possibility to chat, but not more. So the Question basically is, how possible / solvable this issues are allaround, or if I have to find other solutions for this.

  • Sub Menu Rollover Pop up Not Showing

    - by Stradigos
    Hello everyone, hopefully this will be an easy answer for some of you CSS veterans out there. I'm developing a site for a client. For readability, I'll just give you a link to the website and the css page in question. HTML CSS I'm trying to make a sub menu pop up to the right of the main menu when you scroll over "Star Quartz Grout." My current CSS obviously isn't correct though, and I could use some guidance. ul#subNav {display: none; width: 134px; } li:hover ul#subNav, li.over ul#subNav {display: inline-block; position: absolute; top: 0px; left: 134px; } My guess is that it's working but it's hidden behind the rest of the page. I could be wrong though. It's kind of hard to confirm, even with Chrome's "Inspect Element" (very nice thing btw). It's probably some dumb mistake. Anyway, thanks in advance. I'm a bit of a CSS novice.

  • Java RMI InitialContext: Equivalent of LocateRegistry.createRegistry(int) ?

    - by bguiz
    I am trying to some pretty basic RMI: // Context namingContext = new InitialContext(); Registry reg = LocateRegistry.createRegistry(9999); for ( int i = 0; i < objs.length; i++ ) { int id = objs[i].getID(); // namingContext.bind( "rmi:CustomObj" + id , objs[i] ); reg.bind( "CustomObj" + id , objs[i] ); } That works without a hitch, but for future purposes, I need to use InitialContext. Context namingContext = new InitialContext(); for ( int i = 0; i < objs.length; i++ ) { int id = objs[i].getID(); namingContext.bind( "rmi:CustomObj" + id , objs[i] ); } But I cannot get this to work. I have started rmiregistry from the command line. Is there an equivalent of LocateRegistry.createRegistry(int)? Or some other way to start the RMI registry / registry used by InitialContext from inside my class? (Instead of the command line) Stack trace: javax.naming.CommunicationException [Root exception is java.rmi.ServerException: RemoteException occurred in server thread; nested exception is: java.rmi.UnmarshalException: error unmarshalling arguments; nested exception is: java.lang.ClassNotFoundException: bguiz.scratch.network.eg.Student] at com.sun.jndi.rmi.registry.RegistryContext.bind(RegistryContext.java:126) at com.sun.jndi.toolkit.url.GenericURLContext.bind(GenericURLContext.java:208) at javax.naming.InitialContext.bind(InitialContext.java:400) at bguiz.scratch.RMITest.main(RMITest.java:29) Caused by: java.rmi.ServerException: RemoteException occurred in server thread; nested exception is: java.rmi.UnmarshalException: error unmarshalling arguments; nested exception is: java.lang.ClassNotFoundException: bguiz.scratch.CustomObj at sun.rmi.server.UnicastServerRef.oldDispatch(UnicastServerRef.java:396) at sun.rmi.server.UnicastServerRef.dispatch(UnicastServerRef.java:250) ....(truncated) EDIT: I will delete my own question in a couple of days, as there seems to be no answer to this (I haven't been able to figure it out myself). Last call for any biters!
