• Email marketing campaigns [closed]

  - by Bradley Herman

  We're working on building an email marketing campaign for our company and once again, my boss (designer) and I (developer) are butting heads... She wants to create one big image for each of these emails and I'm trying to steer her towards using the traditional header-content-footer method so the text within the content will be viewable when images are blocked. Obviously as a designer, she believes in a happy world where 100% of people will open it to see whatever awesome design she made and click to go to our site. Are there any good statistics or case-studies anyone has seen out there that would help support my stance of design being used to enhance content than design being content?

• jQuery: Any way to "refresh" event handlers?

  - by Legend

  I have two divs, one that holds some stuff and the other with all possible stuff. Clicking on one of the divs will transfer items to the other div. The code I came up with is: $("#holder > *").each(function() { $(this).click(function(e) { $(this).remove(); $("#bucket").append(this); }); }); $("#bucket > *").each(function() { $(this).click(function(e) { $(this).remove(); $("#holder").append(this); }); }); This one works perfectly, except that the event handlers need to be refreshed once I append or remove elements. What I mean is, if I first click on an element, it gets added to the other div, but if I click on this element again, nothing happens. I can do this manually but is there a better way to achieve this?

• Returning an array from an activity

  - by Boardy

  I am currently working on an android project and I want to be able to startActivityForResult so that I can return an array of. The array is an ArrayList<Spanned> lets say its called myArray. From what I've read I can't return an array directly from the activty using the set result so I was thinking that once the array has added all the data to the array, I can then call the toString function on it, i.e. myArray.toString(). If I do this, I have no idea how I can then convert this back into the original ArrayList<Spanned>. Thanks for any help you can provide.

• Singelton restricted to instance of dll

  - by codeySmurf

  If I create a singleton class in the context of a dll, the singleton class is instantiated once and used by all instances of the dll. I am using a dll as a plug-in for an application. Now the following thing came to my mind: If I use a singleton Class, it will be shared across multiple instances of the plug-in. However, this makes it difficult to manage the lifetime of the singleton class efficiently. The only way I could think of would be to use a reference count and to make the singleton delete its self when the reference count is 0. Does anyone have any better ideas on that? Is there any good way to restrict the singleton object to one instance of the dll? Language is c++

• Xml schema, how to make sure one element exists with a specific attribute value

  - by pexxxy

  How do I enforce the existing of an element with a specific attribute value in the XML? For example: <events> <event type="system" desc="this is a system event"/> <event type="bla1" desc="this is bla1 event"/> <event type="bla2" desc="this is bla2 event"/> </events> I need a rule to make sure the event element with type attribute = 'system' exists (once). All other event elements are optional;

• echoing our parts of an Array?

  - by Wes

  I have the following array that I get as an output from facebook: http://www.paste.to/v/1jntlnml With the following code: $stream = $facebook->api_client->stream_get('',128342905144,'0','0',30,'','','',''); foreach($stream as $wallpost) { echo '<pre>'; print_r($wallpost); echo '</pre>'; } So I get the data that I need, but I want to call the individual variables within this array. For example, echo out the [message] for each post. Since it only loops once, I cant echo $wallpost['message'] or anything similar. any idea?

• 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.

• JQuery: After adding some AJAX, some of the jquery code no longer works

  - by fwaokda

  Here's a pastebin link to my entire jQuery code. [ http://pastebin.com/w57ma5Gx ] The "Thumbnails" section was working fine before I added the ajax sections. Anyone can help me with why it quit working? And if I need to I can post another question but figured I'd try it here first. Whats a better way of writing the ajax code where it executes once upon loading the page and then every time I click the $("a#next") link afterwards? Right now I just repasted the code outside of the next link and that works, but seems silly to have the same code in two different places like that. Thanks!

• Load all tab bar views when application first runs

  - by codenoobie

  Here's the problem. I have a tab bar controller with 4 separate views. When I navigate from the first view to the second view, it takes some time to load up the second view. What I want to do is be able to load and initialize all of my tab bar views during my splash screen. That way, when the user navigates between the tab views, there is no wait time. So the question is... how do I manually initialize my individual tab bar views in my app delegate? And once again, thank you stackoverflow!

• How to deploy VS2008 express desktop project?

  - by melaos

  hi guys, i was wondering how could i deploy/make it into an installer for an app which is created using vs 2008 express. i know that the setup and deployment feature is only available via the full version of visual studio right? So are there any add ons or perhaps additional free/or non-free if it has to come to that which i can use to do this? or is the best tool for the job is the old visual studio installer from the vs 6.0 days? :) thanks Updates: After some googling, i found this link on using click once to deploy vs 2008 express with tutorials in them, i'll check it out, but of course more & better recommendation is always welcomed :)

• How would I go about writing a conditional statement to check if visitor is coming from a particular

  - by Matthew

  Hello guys, What I have in mind is this... We are going to have people come from a particular site during a acquisition campaign and was wondering how I could conditionalize a certain section of my site to display a thank you message instead of the sign up form as they would have had the opportunity to fill this out before coming to my landing page. I have seen solutions like: $referal = mysql_real_escape_string($_SERVER['HTTP_REFERER']); I would like to know if this is the best way to get this to work??? - okay this is what i think might work. The third party website that is referring people to our landing page once the form on that site has been filled out can push into the record a hidden input value of "www.sample.com" or whatever... then I can have something check the for that particular value and fire off the conidtional. Does that even sound right?

• Problem TreeView OnTreeNodePopulate event

  - by purnang.advant

  Hi. I am using a treeview in asp.net 3.5(using c#.net),which is populated from sqldatabase. OnTreeNodePopulate event fires this event, protected void tvLabs_TreeNodePopulate(object sender, System.Web.UI.WebControls.TreeNodeEventArgs e) { PopulateSubLevelLab(e.Node.Value, e.Node); //This function is used for populating the child node. FillLabGrid(e.Node.Value);---My Question? } ---My Question? The FillLabGrid method used for fill a grid view on the basis of selecting the treeview parent node. But this function filled the grid only once when i click the parent node for the first time. Secondly when i collapse the treeview and again click on the parent node function (tvLabs_TreeNodePopulate)is not called? Hope you are getting my point. Please advice me. Thanks in advance.

• Publish/Subscribe paradigm: Why must message classes not know about their subscribers?

  - by carleeto

  From Wikipedia: "Publish/subscribe (or pub/sub) is a messaging paradigm where senders (publishers) of messages are not programmed to send their messages to specific receivers (subscribers). Rather, published messages are characterized into classes, without knowledge of what (if any) subscribers there may be" I can understand why a sender must not be programmed to send its message to a specific receiver. But why must published messages be classes that do not have knowledge of their subscribers? It would seem that once the messaging system itself is in place, what typically changes as software evolves is the messages sent, the publishers and the receivers. Keeping the messages separate from the subscribers seems to imply that the subscription model might also change. Is this the reason? Also, does this occur in the real world? I realize this may be a basic question, but I'm trying to understand this paradigm and your replies are very much appreciated.

• How to track when my application has unexpectedly shut down?

  - by Vilx-

  I'm writing an application whose purpose involves a lot of logging of different events. Among those I would also like to have an event that the application was shut down - even if unexpectedly like because of a power loss. Naturally, when the power goes out I don't get a chance to write anything anywhere. So my idea was to continuously write a timestamp in some known location (say, once per minute), and when the application was next run, it could determine the approximate time of the unexpected shutdown. A precision of 1 minute would be acceptable for me. However I'm worried that caching at the OS and disk level might interfere with this approach. Is there a better way or if not - how to make sure that the data I just wrote is REALLY written out to the physical medium? Added: Oh, almost forgot the buzzword line: Windows XP and above; .NET 3.5; C#.

• Emacs and Long Shell Commands

  - by darrint

  Is there a way to run a shell command, have the output show up in a new buffer and have that output show up incrementally? Eshell and other emacs terminal emulators do a find job of this but I see no way to script them. What I'd like to do is write little elisp functions to do stuff like run unit tests, etc. and watch the output trickle into a buffer. The elisp function shell-command is close to what I want but it shows all the output at once when the process finishes.

• Hashing and salting values

  - by Avanst

  I am developing a small web app that internally authenticates users. Once the user is authenticated my web app then passes some information such as userID and Person's name to a third party web application. The third party developer is suggesting that we hash and salt the values. Forgive my ignorance, but what exactly does that mean? I am writing the app in Java. So what I am planning on doing is hashing the userID, Person's name, and some Math.random() value as the salt with Apache Commons Digest Utils SHA512 and passing that hashed string along with the userID and person's name. Is that the standard practice? I should be passing the third party the salt as well correct?

• Export XML with only one MySQL request ?

  - by mere-teresa

  I want to export in XML format some data from 7 tables (MySQL database), and then I want to import in another database. And I have a update or insert rule for data. I already have a SQL query retrieving all data, with JOINs on my 7 tables. But...when I try to put data in XML format, I reach a limit. My PHP loop can catch each row, but I would like to benefit from hierachical structure of the XML, and all I have are rows with the same data repeated. It is better to query once and to construct the XML tree in PHP or to query each time I want access to a lower level ?

• Application window sent behind other windows on closing different thread (C#)

  - by david.murrant

  I'm writing a Windows Forms Application in C#.NET On startup, the application displays a splash screen which is running in a separate thread. Whilst the splash screen is showing, the main application is initialising. Once the main application has finished initialising, the main form of the application is displayed, and the splash screen still shows over the top. Everything so far is as expected. Then, the Splash screen is closed, which causes that thread to exit. For some reason, at the point, the main application windows gets sent behind all other open Windows, notably the Windows Explorer window where you clicked the .exe file to run the application in the first place! What could be causing the windows to suddenly jump "behind" like this?

• How to update (append to) an href in jquery?

  - by John Isaacks

  I have a list of links that all go to a google maps api. the links already have the daddr (destination) parameter in them as static. I am using Geo-Location to find the users position and I want to add the saddr (source address) to the links once I get the data. so basically I will need to add something like &saddr=50.1234567,-50.03452 at the tail end of all the links pointing to google maps All the links have a class called directions-link and from this page I have figured out how to change them: $("a.directions-link").attr("href", "http://www.google.com/"); However I only want to append my value to the end of the href without changing what the href already is. How can I do that? Thanks!!

• Grabbing Just The Top Entry From A LINQ Query

  - by Soo

  I basically have a lot of poorly designed code to do something that, I'm sure, can be done far more elegantly. What I'm trying to do is grab the last date from a database table. var Result = from a in DB.Table orderby a.Date descending select new {Date = a}; foreach(var Row in Result) { LastDate = Row.Date.Date; break; } Basically, there's a foreach loop that is designed to run only once. Crappy code! What's a "best practice" way to accomplish the same thing?

• Client to server data upload

  - by RickBowden

  I'm trying to design a system similar to the traditional server monitoring systems like MOM, Tivoli, Open View, where an agent will record data and then upload it to a central database once a day, but them also be able to send immediate alerts back to the server. I'm not sure what the best methodology might be for this. I've started looking at Microsoft sync services but I'm not sure if it will fit my needs. I'm using VS2008 and C#. Does anyone have any experience or ideas about how I should go about this task?

• FULLTEXT Irrelevant results

  - by Imran Omar Bukhsh

  Just came across this issue using the fulltext search of mysql. I have like 250 records ( long articles like stuff ) and am using the fulltext MATCH AGAINST IN BOOLEAN MODE. Now if I search for a keyword e.g. 'Samsung' and if this keyword is present in ALL the records then it returns all the 250 records which it should ( of course without `IN BOOLEAN MODE it would return nothing as the keyword is present in more than 50% of the records ). Now the problem is that in some articles the keyword 'Samsung' occurs once and in others a couple of times, but MYSQL is giving a score of 1 to all the records returned, even those which have 'Samsung' like 15 times in them.

• Replacing Text in a Toggled Anchor with JQuery

  Hi I'm trying to change the text in an anchor on toggle. I'm doing this way at the moment but have found that once the anchor markup has replaced the toggle no longer works. Can someone please explain why this is happening and a solution? Many thanks. $('a#toggleHeader').toggle(function() { $('#header-wrapper').slideUp(); $(this).replaceWith('< href=\"#\" id="toggleHeader">Show Header</>'); //Note:I've move the anchor because I can only post one anchor as a new user },function(){ $('#header-wrapper').slideDown(); $(this).replaceWith('<a href=\"#\" id="toggleHeader">Hide Header</a>'); });

• Python: Picking an element without replacement

  - by wpeters

  I would like to slice random letters from a string. Given s="howdy" I would like to pick elements from 's' without replacement but keep the index number. For example >>> random.sample(s,len(s)) ['w', 'h', 'o', 'd', 'y'] is close to what I want, but I would actually prefer something like [('w',2), ('h',0), ('o',1), ('d',3), ('y',4)] with letter-index pairs. This is important because the same letter appears in 's' more than once. ie) "letter" where 't' appears twice but I need to distinguish the first 't' from the 'second'. Ideally I actually only need to pick letters as I need them but scrambling and calculating all the letters in a list (as shown above) is ok.
