  • mix together cck imageField and videoField in one ordered list

    - by Patrick
    hi, I'm using imageField and videoField into each node of my website and I'm using multiple files option, so that I have 2 ordered lists. This works great, however I would like to have only 1 ordered list instead of 2, so that my customer can arrange video and images in the same list and ordered them i.e. video1 image1 video2 video3 image2 ... etc thanks

  • Are there any C++ style and/or standard example files available?

    - by Harvey
    While there are lots of questions about coding style, beautifying, and enforcement, I haven't found any example C++ files that are used as a quick reference for style. The file should be one or two pages long and exemplify a given coding standard/style. For example, the Google C++ Style Guide is a great reference, but I think a one to two page piece of code written in their style pinned to a wall would be more useful in day-to-day use. Do any of these already exist?

  • Line Graph CGPoints from NSMutableArray

    - by Mattog1456
    I have been trying to adapt the code from the accelerometer example such that when the user depresses a uibutton a point is added to a line graph. Working on the converting two floats, which are the result of calculate as below into a CGPoint and converting the CGPoint into an NSValue and then adding this to a NSMutableArray with the following -(IBAction)calculate:(id)sender { self.points = [NSMutableArray array]; CGPoint pt = CGPointMake(d, c); [self.points addObject:[NSValue valueWithCGPoint:pt]]; NSLog(@"%@", NSStringFromCGPoint(pt)); NSLog(@"%@", [NSString stringWithFormat:@"%d points", self.points.count ]); } But for some reason I am only getting one object stored in the array, it seems everytime push the calculate button the object pt gets overwritten, on the plus side it has the correct x,y coords. Any ideas on this one? UPDATE Removed self.points = [NSMutableArray array]; and placed it in view did load, also set the first points to 0,0. so that is working ok. Now the next problem is that I have a Graph subclass where the CG Drawing is taking place. I am trying to figure out a simple way to be able to access the above NSMutableArray which is in a ViewController class from the graph class. Am so close to the end but am really stuck, any help would be great. Still trying to draw a line graph on a UIView which is on a UIScrollview. The draw rect method is in the UIView Subclass and everything is working there, I have gridlines and labels on the axis and I can draw manually onto it. But the problem I have is that I cannot read the NSMutableArray of the CGPoints, which are the x and y coords. The ViewController performs a calculation and the results are written to the NSMutable array and this is all working fine as well, I can see the CGpoints and their values being written with NSLogs in the ViewController. I have tried various ways to set the NSMutableArray up as a global but to no avail, everything runs but while I can see the points being written in the ViewController they are just not visible to the UIView Subclass. I have also tried to use the addObserver and observeValueForKeyPath methods and once again while everything runs the subclass cannot see the array. Any ideas, suggestions, tips or thoughts would be great

  • Which mail server would you choose to develop your product on top of

    - by Tzury Bar Yochay
    I am willing to build an email application which runs on the server side. Not being familiar with any particular server I wonder if I can get some recommendations based on experience. I have seen many great startups which built some neat apps on the email platform (for instance, friendfeed's notification mechanism, or surely posterous which mail is at the heart of their business logic), and wonder about which mail server have they found easy to learn and integrate with. PS: MS Exchange or any other not open-source are not an option Must run on linux

  • YUI vs jQuery, for css style layouts

    - by tony
    Hi Complete novice question. I've used jQuery a bit, YUI not at all and know very little about it. I work on a website thats IE specific, we're now looking at making it cross browser. jQuery seems great at hiding the differences between browsers from a javascript point of view. However in terms of css layout is it YUI that I should really be looking at? thanks

  • Using C# to read/write from excel spreadsheet.

    - by Aaron
    Hi there, I need to make a program that writes some data to an excel spreadsheet. Something basic along the lines of First name, last name, phone number, e-mail per row with each category in its own column. I don't even know where to start. If someone could tell me which assemblies to reference and maybe point me to a website or a book that covers writing/reading data from an excel spreadsheet via a c# program that would be great. Many thanks.

    - by Abs
    Hello all, I add html to a page using JQuery's html() function. This works great on most browsers except IE6. I can work round this by adding a click event etc but I want to fix the issue without extra tape! Any ideas why this doesn't work on IE6? $('#button_holder').html('<a href="#" onclick="run_activity_upload(); return false;" id="save_button">Upload</a>'); Thanks, Abs

  • Are there any scripts to synchronize sites?

    - by Matrym
    I've just set up a fail-over DNS to switch the site to a second host if the first is down. This is great for showing an old / archived version of the site, but I suspect maintenance is going to be a real pain. I moved the files over with rsync in the first place. Is this the kinda thing that could be run as a cron job, automatically moving over newer files?

  • mySQL JOIN wont return results with 0 count

    - by MPC
    SELECT categories.*, COUNT(categoryID) AS kritCount FROM categories AS categories LEFT JOIN krits ON categories.id = categoryID WHERE (krits.approved = '1') GROUP BY categories.id So this works great except that it does not return a category that has a 0 count of krits in the category. It will if I remove the WHERE statement but I need the WHERE to only select the krits where the field approved = 1

  • CGRect and utesting

    - by killdash10
    I am trying to add unit tests to my iPhone project in Xcode. Everything works, its great. Except when I am adding a class.m that uses CGRect (or other structs, CGPoint etc) to the unit test target (under "Compile Sources") - I am getting a compilation error: "'CGRect' undeclared (first use in this function)". I tried messing with my unit test target in various ways, but so far I haven't been able to get past this. What am I missing?

  • javascript ul button dropdown crashes after if doing more than 1 button

    - by Apprentice Programmer
    So i have a button drop down list that i want users to select a choice, and basically the button will return the users selection.Pretty straight forward, tested on jsFiddle and works great. Using ruby on rails btw, so i'm not sure if it might conflicting the way rails handle javascript actions. Heres the code: <%= form_for(@user, :html => {:class => 'form-horizontal'}) do |f| %> <fieldset> <p>Do you have experience in Business? If yes, select one of the following: <div class="input-group"> <div class="input-group-btn btn-group"> <button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown">Select one <span class="caret"></span></button> <ul class="dropdown-menu"> <li ><a href="#">Entrepreneurship</a></li> <li ><a href="#">Investments</a></li> <li ><a href="#">Management</a></li> <li class="divider"></li> <li ><a href="#">All of the Above</a></li> </ul> </div><!-- /btn-group --> <%= f.text_field :years_business , :class => "form-control", :placeholder => "Years of experience" %> </div> Now there are 2 more of these, and basically what happens is that if I select an item for the first time from the dropdown list, everything works great. But the moment I select the same button/or new button, the page immediately kind of refreshes, they selected value will not show up after the list drops down and user selects a value. I viewed the page source and added additional javascript src and types, but still doesnt work. the jquery code: jQuery(function ($) { $('.input-group-btn .dropdown-menu > li:not(.divider)').click(function(){ $(this).closest('ul').prev().text($(this).text()) }) }); Any suggestions what is causing the problem?? The jsfiddle link is here: http://jsfiddle.net/w4s8u/7/
