• How to make a chat application for web similar to gmail popup?

  - by Nitesh Panchal

  Hello, As you must have seen in gmail, a small popup appears to chat when you click on right bottom corner of your screen. Interestingly, this popup remains open and at the same place even when we navigate from one webpage to another. How can this be done? It doesn't look as though it's different page. Is it different page altogether? or is it the same page? Thanks in advance :). Hope these moderators don't close my question. Last time i asked something that would have been useful to me, they negatively voted me and closed my question.

• Full automatic application trace for .net v4

  - by JL

  I would like to implement a way to trace every line of code in an application that is written for .net v4.0. An example would be. If I had the following function. private bool hasValue(string value) { if(string.isnullorempty(value) { return false; } else { return true; }} Then when the function is called I want detailed trace logs to contain something like this: Function called |Line 10 |Signature private bool hasValue(string value)|ValuesPassed hasValue("") Line Evaluated | Line 11 | if(string.isnullorempty(value) |ValuesPassed if(string.isnullorempty("") - evaluation returned true entered line 13 |signature return false|return action taken. This tracing can be done manually, but its a lot of work, and would dirty the code. Isn't there a way to get this level of tracing automatically with .net or 3rd party plugin? Thank you

• Google app engine-php: script handler

  - by Eve

  I try to create php web app using GAE. In the GAE tutorial, "A script handler executes a PHP script to handle the request that matches the URL pattern. The mapping defines a URL pattern to match, and the script to be executed" Now I want to map the url with the file having same name in the folder, e.g. if the url is /hello.* , it will map the file name hello.php in the folder. And if it is /hello1.*, hello1.php in the folder will be responded to the server. I thought this should be done directly by mapping the name of the url with the name in the folder. But if I left empty for the handler in the app.yaml, I got an error. So I want to know how to set up the handler in app.yaml?

• iPhone : Primitives getters and setters

  - by Burf2000

  I feel a bit miffed at the moment, I done a few iPhone projects that use floats and ints etc and all is fine. I now using OpenGL and GLFloat[] C arrays etc and it seems unless I make methods to set / get them it crashes on the device (not the simulator). Now as these are not setup as properties (I don't think c arrays can) it kind of makes sense. However the project has been working for months without them. It seems something in the code is wiping out anything float / ints to the point that the debugger can see an assigned value but accessing it crashes the phone. As soon as I think I know something for this platform, something changes my mind lol.

• Continuously reading from a stream in C#?

  - by Damien Wildfire

  I have a Stream object that occasionally gets some data on it, but at unpredictable intervals. Messages that appear on the Stream are well-defined and declare the size of their payload in advance (the size is a 16-bit integer contained in the first two bytes of each message). I'd like to have a StreamWatcher class which detects when the Stream has some data on it. Once it does, I'd like an event to be raised so that a subscribed StreamProcessor instance can process the new message. Can this be done with C# events without using Threads directly? It seems like it should be straightforward, but I can't get quite get my head around the right way to design this.

• Overlapping divs, absolutely relative?

  - by askon

  A wordpress theme I'm working on has headlines which span across the entire content area. These headlines are overlapped by the sidebar which is absolutely positioned at 100% width. The issue, is when the sidebar's content exceeds the page's content, it stretches OUT of my wrapper overtop of the footer without forcing the it down (because it's absolute and nothing else is). So my question is, how would it be possible to make a absolutely positioned div, become relative and essentially "push" my footer down, or is there a better way to do this? Also, if anyone has examples of how this has been done would be awesome! edit: The sidebar is absolutely positioned so it can lay over top of the sidebar. I don't have an online example as I'm doing doing a local server set-up, everything else is relatively position, and likely floated. Image Example: http://imagecheese.com/gallery/stackquest.png

• Why are Objective-C instance variables declared in an interface?

  - by Chase

  I'm just getting into Objective-C (Java is my primary OO language). Defining an object's instance variables in the interface instead of the class seems strange. I'm used to an interface being a public API definition with nothing besides method signatures (not counting constants here). Is there some reason that state is defined in an interface (even if it is private) and behaviour is defined in a class. It just seems odd that since objects are state+behavior that the definition would be split into two separate places. Is it a design benefit is some way? A pain in the rear issue that you are just forced to deal with in Objective-C? A non-issue, just different? Any background on why it's done this way? Or can you put object state in a class and I just haven't hit that part in my book yet?

• UI Design - design pattern for city/country drop down? (ASP.NET MVC)

  - by JK

  What is the best way to do a city/country dropdown pair in ASP.NET MVC? I see lots of places with country above city, but that's unnatural: in real life we write city/country. I've used city, then country, but the problem is that the user then has to go backwards after changing the country. The other problem is what do you do about cities/countries not in your list? If city/country are both drop downs, then the user cant type their own city if it is missing. But if you have a dropdown and a textbox, that makes it unwieldy (you end up with 4 controls to enter 2 pieces of data). Are there any examples websites where the city/country dropdown pair are done in a very useable and clear manner?

• How to know if the website being scraped has changed?

  - by Lost_in_code

  I'm using PHP to scrape a website and collect some data. It's all done without using regex. I'm using php's explode() method to find particular HTML tags instead. It is possible that if the structure of the website changes (CSS, HTML), then wrong data may be collected by the scraper. So the question is - how do I know if the HTML structure has changed? How to identify this before storing any data to my database to avoid wrong data being stored.

• Compress small strings, With what to create external dictionary?

  - by Chris

  I want to compress much small strings (about 75-100 length c# string). At the time the dictionary is created I already know all short strings (nearly a trillion). There will no additional short strings in future. I need to extra exactly one string without decompress other strings. Now I am looking for a library or the best way to do the following: Create a dictionary using all strings I have Using this dictionary to compress each string a way to compress one string using the dictionary from 1. I found a good related question, but this is not c# specific. Maybe there is something for c# I do not know, or a fancy library or someone has already done that. That is the reason I ask this question.

• Manually manipulating ArrayList

  - by jsan

  I have an assignment where I have to create a deque, however I am not allowed to use any built-in classes or interfaces. I am implementing my deque using an array list. My problem is that when I have to, for instance, add to the beginning of the array list (beginning of the queue), i am not allowed to do this: public void addFirst(ArrayList<Integer> array) { array.add(0, int); } Is there a way to do this without using the add() function? Such as manually adding to the front and shifting the rest of the array to the right? Or maybe creating a new array list and copying...I'm not sure. Any help would be great; I have a bunch of functions to write, and getting the first one done will definitely put me in the right direction. Thanks

• delete all records except the id I have in a python list

  - by jay_t

  Hi all, I want to delete all records in a mysql db except the record id's I have in a list. The length of that list can vary and could easily contain 2000+ id's, ... Currently I convert my list to a string so it fits in something like this: cursor.execute("""delete from table where id not in (%s)""",(list)) Which doesn't feel right and I have no idea how long list is allowed to be, .... What's the most efficient way of doing this from python? Altering the structure of table with an extra field to mark/unmark records for deletion would be great but not an option. Having a dedicated table storing the id's would indeed be helpful then this can just be done through a sql query... but I would really like to avoid these options if possible. Thanks,

• Is there a way to have a dynamic google map that opens links in _blank?

  - by danieltalsky

  I came up with a good solution for a client showing a google map iFrame using the normal google maps embed. Only problem? They want the links inside the iFrame to open in a new window instead of there on the page. So, I used the static API to come up with a static image of a map and have that link to the google maps site with target="_blank". Great, but they don't get the pretty draggable map. Is there a way to do what I want using the google maps API? I'm reading the API documentation but without actually trying it I'm not sure if it can be done, and would love it if someone with some experience with the API can point me in the right direction or just tell me why it's WAY not worth the effort.

• .NET's double.NaN - how does this counterintuitive feature work?

  - by GeReV

  I stumbled upon the definition of double.NaN in code: public const double NaN = (double)0.0 / (double)0.0; This is done similarly in PositiveInfinity and NegativeInfinity. double.IsNaN (with removing a few #pragmas and comments) is defined as: [Pure] [ReliabilityContract(Consistency.WillNotCorruptState, Cer.Success)] public static bool IsNaN(double d) { if (d != d) { return true; } else { return false; } } This is, by far, the most counterintuitive thing I have ever seen in the .NET framework. How is 0.0 / 0.0 represented "behind the scenes"? How can division by 0 be possible in double, and why does NaN != NaN?

• How to retrieve the TabHost object, if you're not using TabActivity?

  - by Lee Olayvar

  I am attempting to use a few of the simple android examples for Tab Views. One thing i am attempting to do different than all the examples i've seen so far, is to not use a TabActivity. I am trying to use a normal activity, which means i need to retrieve the TabHost object some how, so i can add tabs and etc to it. How can this be done? If you wanted to retrieve a view, you can simply use findViewById(R.id.blah), but how can you retrieve the TabHost object in a similar manner?

• Knowledge mining using Hadoop.

  - by Anurag

  Hello there, I want to do a project Hadoop and map reduce and present it as my graduation project. To this, I've given some thought,searched over the internet and came up with the idea of implementing some basic knowledge mining algorithms say on a social websites like Facebook or may stckoverflow, Quora etc and draw some statistical graphs, comparisons frequency distributions and other sort of important values.For searching purpose would it be wise to use Apache Solr ? I want know If such thing is feasible using the above mentioned tools, if so how should I build up on this little idea? Where can I learn about knowledge mining algorithms which are easy to implement using java and map reduce techniques? In case this is a wrong idea please suggest what else can otherwise be done on using Hadoop and other related sub-projects? Thank you

  - by robUK

  Hello, gcc 4.4.4 c89 Visual Studio VC++ 2008 I am writing a cross platform client server application. It will run on both linux and windows.

• Bash Scripting: I want to open a set of .html files, and add line before html tag

  - by Bashn00b

  Hi guys, I have a set of .php files in a folder, I want to add text just before these lines: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en" > What i want is to insert just before these lines in the html file. So just want to prepend that file before each docType declaration. However the DOCTYPE declaration is never on line 1, as there is loads of php lines before. I have this current script (where FE is the folder containing all the scripts i want to edit): for file in ${fe}*; do echo "$file" done Thanks,

• Strings - Filling In Leading Zeros Wtih A Zero

  - by headscratch

  I'm reading an array of hard-coded strings of numeric characters - all positions are filled with a character, even for the leading zeros. Thus, can confidently parse it using substring(start, end) to convert to numeric. Example: "0123 0456 0789" However, a string coming from a database does not fill in the leading zero with a 'zero character', it simply fetches the '123 456 789', which is correct for an arithmetic number but not for my needs and makes for parsing trouble. Before writing conditionals to check for leading zeros and adding them to the string if needed, is there a simple way of specifying they be filled with a character ? I'm not finding this in my Java book... I could have done the three conditionals in the time it took to post this but, this is more about 'education'... Thanks

• Framework for creating mock objects in Java

  - by Amir Rachum

  This is NOT a question about which is the best framework, etc. I have never used a mocking framework and I'm a bit puzzled by the idea. How does it know how to create the mock object? Is it done in runtime or generates a file? How do you know its behavior? And most importantly - what is the work flow of using such a framework (what is the step-by-step for creating a test). Can anyone explain? You can choose whichever framework you like for example, just say what it is.

• Java using enum with switch statement

  - by MisterSquonk

  I've looked at various Q&As on SO similar to this question but haven't found a solution. What I have is an enum which represents different ways to view a TV Guide... static enum guideView { GUIDE_VIEW_SEVEN_DAY, GUIDE_VIEW_NOW_SHOWING, GUIDE_VIEW_ALL_TIMESLOTS } ...when the user changes the view an event handler receives an int from 0-2 and I'd like to do something like this... // 'which' is an int from 0-2 switch (which) { case NDroid.guideView.GUIDE_VIEW_SEVEN_DAY: ... break; } I'm used to C# enums and select/case statements which would allow something like the above and I know Java does things differently but I just can't make sense of what I need to do. Am I going to have to resort to if statements? There will likely only ever be 3 choices so I could do it but I wondered how it could be done with switch-case in Java.
