• In App Purchase Unique Identifying Data

  - by dageshi

  O.K so I'm writing a iPhone travel guide, you purchase a subscription to a travel guide for 3 months, it downloads a fairly hefty database and for 3 months that database gets updated weekly with new stuff. Now what I'd like to do is make the user enter their email address as a one off action before they purchase their first guide, for China say. The purpose for doing this is 1) To allow me to contact the user by email when they add a note/tip for a particular place (the app will allow them to send notes & information to me) 2) To Uniquely identify who has purchased the subscription so that if they wipe their device and reinstall the app they can plug the email address in and pickup their subscriptions again. Or so they can use the same subscription on another device they own. My concerns are 1) Will Apple allow the email method of restoring functionality to a second or restored device? 2) As long as I tell the user what I'm using their email address for (aka I won't sell it to anyone else and use it for X purposes) will it be o.k to ask for said email address? And as a side note, can I tack the devices unique id onto my server comms to track devices or is apple going to through a hissy fit about that as well?

• grabbing layer contents in a class

  - by Mike

  I have a custom UIImageView class that creates thumbnails (UIImageView) and each thumbnail has a label. The label is created by another class. The label class creates a UIImageView and a UITextView on top of it. This is the init object class' init method: - (id)initWithFrame:(CGRect)frame { if ([super initWithFrame:frame] == nil) { return nil; } CGRect myFrame = CGRectMake(0, 0, 100, 100); myLabel = [[myLabelClass alloc] initWithFrame: myFrame]; //myLabelClass is a UIImageView based class [myLabel setCenter:CGPointMake(50, 50)]; [self addSubview: myLabel]; return self; } So, I have this MAIN VIEW CONTROLLER | |___ UIImageView WITH LABEL | |____ label background (UIView) |____ UITEXTVIEW (text) Now I want to write the contents of all these 3 components to a quartz context. I need to write using drawInRect, because I need to write the full object to a precise location. I expected object.layer.contents to be the image equivalent to these 3 "layers" flattened, in other words, the object's image, the label background and the label text, as it would if I created these 3 objects in Photoshop and flatten the composition. I also expect object.myLabel.layer.contents to contains the rendered contents of the UITextView over the label background. The problem is that when I use UIImage *myImage = [UIImage imageWithCGImage:objecto.myLabel.layer.contents]; [myImage drawInRect:CGRectMake(0, 0, 100, 100)]; I get nothing. How can I obtain a "flattened" image resultant to the full object (including its subviews)? thanks

• How can I tell when something outside my UITableViewCell has been touched?

  - by kk6yb

  Similar to this question I have a custom subclass of UITableViewCell that has a UITextField. Its working fine except the keyboard for doesn't go away when the user touches a different table view cell or something outside the table. I'm trying to figure out the best place to find out when something outside the cell is touched, then I could call resignFirstResponder on the text field. If the UITableViewCell could receive touch events for touches outside of its view then it could just resignFirstResponder itself but I don't see any way to get those events in the cell. The solution I'm considering is to add a touchesBegan:withEvent: method to the view controller. There I could send a resignFirstResponder to all tableview cells that are visible except the one that the touch was in (let it get the touch event and handle it itself). Maybe something like this pseudo code: - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { CGPoint touchPoint = // TBD - may need translate to cell's coordinates for (UITableViewCell* aCell in [theTableView visibleCells]) { if (![aCell pointInside:touchPoint withEvent:event]) { [aCell resignFirstResponder]; } } } I'm not sure if this is the best way to go about this. There doesn't seem to be any way for the tableviewcell itself to receive event notifications for events outside its view.

• How to deal with clients and iterations in Agile team?

  - by Ondrej Slinták

  This thread is a follow up to my previous one. It's in fact 2 questions, so I hope no one minds, as they are dependent on each other. We are starting a new project at work and we consider it as a great opportunity to try Agile techniques in action. We had a brainstorming about ideas we read in several books and articles, and came up with concept that would suit us the best: 2 weeks iteration, followed by call with clients who would choose what stuff they want to have in next iteration. I just have few more questions, which we couldn't figure out ourselves. What to do in the first iteration? What to, generally, do in the first few iterations if we start from the scratch? Just give it a month of development to code core of the application or start with simple wire-frames with limited pre-coded functionality? What usually clients want to see? Shiny stuff that doesn't work or ugly stuff that does work? How to communicate with clients? Our initial thought it to set the process to something like this: Is it a good idea to have a Focal Point on client side or is it better to communicate straight with all the clients to prevent miscommunication? Any thoughts are welcome! Thanks in advance.

• Encrypt a file base upon a pregenerated "key" C#

  - by Anubis

  Hello everyone. I'm trying to determine the best course of action to implement a simple "licensing" system with a partner of mine. The concept is: Generate an encrypted value based upon several internal hardware components. Have the customer send this value to us which we will implement into our key generator. Once we have that, we add any other restrictions on the license (user, expires, etc.). From there we generate a file which we send to the customer they can add to their installation and voila, happy people about. I have the first part all done. My next part is trying to figure out which encryption methodology I would need to use. I already know Symmetric Encryption is pretty much the only route I can take. Most of the information I have found involves .NET already creating a key from its own internal methods. That's a bit of background, my question is: "Which encryption method could I use which would allow me to encrypt the restrictions based upon the "id" I was given from the customer's computer?" I'm writing this in C# by the way. Any ideas would be greatly appreciated! Take Care!

• Adding select menu default value via JS?

  - by purpler

  Hi, i'm developing a meta search engine website, Soogle and i've used JS to populate select menu.. Now, after the page is loaded none of engines is loaded by default, user needs to select it on his own or [TAB] to it.. Is there a possibility to preselect one value from the menu via JS after the page loads? This is the code: Javascript: // SEARCH FORM INIT function addOptions(){ var sel=document.searchForm.whichEngine;for(var i=0;i<arr.length;i++){ sel.options[i]=new Option(arr[i][0],i)}} function startSearch(){ searchString=document.searchForm.searchText.value;if(searchString!=""){ var searchEngine=document.searchForm.whichEngine.selectedIndex; var finalSearchString=arr[searchEngine][1]+searchString;location.href=finalSearchString}return false} function checkKey(e){ var character=(e.which)?e.which:event.keyCode;if(character=='13'){ return startSearch()}} // SEARCH ENGINES INIT var arr = new Array(); arr[arr.length] = new Array("Web", "http://www.google.com/search?q="); arr[arr.length] = new Array("Images", "http://images.google.com/images?q="); arr[arr.length] = new Array("Knoweledge","http://en.wikipedia.org/wiki/Special:Search?search="); arr[arr.length] = new Array("Videos","http://www.youtube.com/results?search_query="); arr[arr.length] = new Array("Movies", "http://www.imdb.com/find?q="); arr[arr.length] = new Array("Torrents", "http://thepiratebay.org/search/"); HTML: <body onload="addOptions();document.forms.searchForm.searchText.focus()"> <div id="wrapper"> <div id="logo"></div> <form name="searchForm" method="POST" action="javascript:void(0)"> <input name="searchText" type="text" onkeypress="checkKey(event);"/> <span id="color"></span> <select tabindex="1" name="whichEngine" selected="Web"></select> <br /> <input tabindex="2" type="button" onClick="return startSearch()" value="Search"/> </form> </div> </body>

• Overriding content_type for Rails Paperclip plugin

  - by Fotios

  I think I have a bit of a chicken and egg problem. I would like to set the content_type of a file uploaded via Paperclip. The problem is that the default content_type is only based on extension, but I'd like to base it on another module. I seem to be able to set the content_type with the before_post_process class Upload < ActiveRecord::Base has_attached_file :upload before_post_process :foo def foo logger.debug "Changing content_type" #This works self.upload.instance_write(:content_type,"foobar") # This fails because the file does not actually exist yet self.upload.instance_write(:content_type,file_type(self.upload.path) end # Returns the filetype based on file command (assume it works) def file_type(path) return `file -ib '#{path}'`.split(/;/)[0] end end But...I cannot base the content type on the file because Paperclip doesn't write the file until after_create. And I cannot seem to set the content_type after it has been saved or with the after_create callback (even back in the controller) So I would like to know if I can somehow get access to the actual file object (assume there are no processors doing anything to the original file) before it is saved, so that I can run the file_type command on that. Or is there a way to modify the content_type after the objects have been created.

• How do I control the background color during the iPhone flip view animation transition?

  - by Rob S.

  I have some pretty standing flipping action going on: [UIView beginAnimations:@"swapScreens" context:nil]; [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:self.view cache:YES]; [UIView setAnimationDuration:1.0]; [self.view exchangeSubviewAtIndex:0 withSubviewAtIndex:1]; [UIView commitAnimations]; To Apple's credit, this style of animation is amazingly easy to work with. Very cool, and I've been able to animate transitions, flips, fades etc. throughout the app very easily. Question: During the flip transition, the background visible 'behind' the two views during the flip is white and I'd like it to be black. I've: Set the background of the containing view (self.view above) - no dice. I really thought that would work. Set the background of each view to black - no dice. I didn't think this would work although you give different things a shot to understand better :) Google'd like crazy; keep landing on Safari-related listings. Thanks in advance!

• iPhone SDK math - pythagorean theorem problem!

  - by Flafla2

  Just as a practice, I am working on an app that solves the famous middle school pythagorean theorem, a squared + b squared = c squared. Unfortunately, the out-coming answer has, in my eyes, nothing to do with the actual answer. Here is the code used during the "solve" action. - (IBAction)solve { int legoneint; int legtwoint; int hypotenuseint; int lonesq = legoneint * legoneint; int ltwosq = legtwoint * legtwoint; int hyposq = hypotenuseint * hypotenuseint; hyposq = lonesq + ltwosq; if ([legone.text isEqual:@""]) { legtwoint = [legtwo.text intValue]; hypotenuseint = [hypotenuse.text intValue]; answer.text = [NSString stringWithFormat:@"%d", legoneint]; self.view.backgroundColor = [UIColor blackColor]; } if ([legtwo.text isEqual:@""]) { legoneint = [legone.text intValue]; hypotenuseint = [hypotenuse.text intValue]; answer.text = [NSString stringWithFormat:@"%d", legtwoint]; self.view.backgroundColor = [UIColor blackColor]; } if ([hypotenuse.text isEqual:@""]) { legoneint = [legone.text intValue]; legtwoint = [legtwo.text intValue]; answer.text = [NSString stringWithFormat:@"%d", hypotenuseint]; self.view.backgroundColor = [UIColor blackColor]; } } By the way, legone, legtwo, and hypotenuse all represent the UITextField that corresponds to each mathematical part of the right triangle. Answer is the UILabel that tells, you guessed it, the answer. Does anyone see any flaws in the program? Thanks in advance!

• How to access global variable in a view in Ruby on Rails?

  - by ben

  I have a User model. I have a Session controller, in which I have a global user variable that is assigned as follows: $user = User.authenticate(params[:session][:email], params[:session][:password]) (I've made user global just to try to solve this problem, so if there's a better way please let me know!) I need to use the email of the logged in user as a parameter to send to Flex part of my website. At the moment I'm creating the link as follows: <%= link_to "secondpage", secondpage_path(:email => @session.$user.email) But I'm getting the following error: compile error /Users/benhartney/rails_projects/talk/app/views/layouts/_header.html.erb:12: syntax error, unexpected tGVAR ..._path(:email = @session.$user.email) ).to_s); @output_buffe... There's also a little arrow pointing at $user If I remove the $ from $user, I get this error: undefined method `user' for nil:NilClass If I remove the (:email => @session.user.email) part, everything works fine, so I think all of the code except for this is ok. Can anyone tell me what I'm doing wrong? Thanks for reading!

• jQueryUI Modal confirmation dialog on form submission

  - by DavidYell

  I am trying to get a modal confirmation dialog working when a user submits a form. My approach, I thought logically, would be to catch the form submission. My code is as follows, $('#multi-dialog-confirm').dialog({ autoOpen: false, height: 200, modal: true, resizable: false, buttons: { 'Confirm': function(){ //$(this).dialog('close'); return true; }, 'Cancel': function(){ $(this).dialog('close'); return false; } } }); $('#completeform').submit(function(e){ e.preventDefault(); var n = $('#completeform input:checked').length; if(n == 0){ alert("Please check the item and mark as complete"); return false; }else{ var q = $('#completeform #qty').html(); if(q > 1){ $('#multi-dialog-confirm').dialog('open'); } } //return false; }); So I'm setting up my dialog first. This is because I'm pretty certain that the scope of the dialog needs to be at the same level as the function which calls it. However, the issue is that when you click 'Confirm' nothing happens. The submit action does not continue. I've tried $('#completeform').submit(); also, which doesn't seem to work. I have tried removing the .preventDefault() to ensure that the form submission isn't completely cancelled, but it doesn't seem to make a difference between that and returning false. Not checking the box, show and alert fine. Might change to dialog at some point ;), clicking 'Cancel' closes the dialog and remains on the page, but the elusive 'Confirm' buttons seems to not continue with the form submission event. If anyone can help, I'd happily share my lunch with you! ;)

• form not identifying the new input fields generated through a javascript

• How to call a function from another class file

  - by Guy Parker

  I am very familiar with writing VB based applications but am new to Xcode (and Objective C). I have gone through numerous tutorials on the web and understand the basics and how to interact with Interface Builder etc. However, I am really struggling with some basic concepts of the C language and would be grateful for any help you can offer. Heres my problem… I have a simple iphone app which has a view controller (FirstViewController) and a subview (SecondViewController) with associated header and class files. In the FirstViewController.m have a function defined @implementation FirstViewController (void) writeToServer:(const uint8_t ) buf { [oStream write:buf maxLength:strlen((char)buf)]; } It doesn't really matter what the function is. I want to use this function in my SecondViewController, so in SecondViewController.m I import FirstViewController.h import "SecondViewController.h" import "FirstViewController.h" @implementation SecondViewController -(IBAction) SetButton: (id) sender { NSString *s = [@"Fill:" stringByAppendingString: FillLevelValue.text]; NSString *strToSend = [s stringByAppendingString: @":"]; const uint8_t *str = (uint8_t *) [strToSend cStringUsingEncoding:NSASCIIStringEncoding]; FillLevelValue.text = strToSend; [FirstViewController writeToServer:str]; } This last line is where my problem is. XCode tells me that FirstViewController may not respond to writeToServer. And when I try to run the application it crashes when this function is called. I guess I don't fully understand how to share functions and more importantly, the relationship between classes. In an ideal world I would create a global class to place my functions in and call them as required. Any advice gratefully received.

• search form in php via ajax

  - by fusion

  i've a search form wherein the database query has been coded in php and the html file calls this php file via ajax to display the results in the search form. the problem is, i would like the result to be displayed in the same form as search.html; yet while the ajax works, it goes to search.php to display the results. search.html: <!DOCTYPE html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <script src="scripts/search_ajax.js" type="text/javascript"></script> </head> <body> <form id="submitForm" method="post"> <div class="wrapper"> <div class="field"> <input name="search" id="search" /> </div><br /> <input id="button1" type="submit" value="Submit" class="submit" onclick="run_query();" /><br /> </div> <div id="searchContainer"> </div> </form> </body> </html> if i add action="search.php" to the form tag, it displays the result but on search.php. i'd like it to display on the same form [i.e search.html, and not search.php] if i just add the javascript function [as done above], it displays nothing on search.html

• Multiple remote_form_for on the same page causes duplicate ids

  - by Ben Scheirman

  I've got a rails app that displays a list of items called modules. I'm iterating over these, rendering a partial for each one that includes a remote_form_for call. This all works, but fails HTML validation because my form text fields all have the same id. Is there a :prefix option on the form (or something else) I can use to get around this? Update: (some code) //_module_form.html.erb <% remote_form_for app_module do |f| %> <%= f.label :name %> <%= f.text_field :name %> <%= submit_tag 'Save' %> <%end %> //parent page <% @thing.modules.each do |app_module| %> <%= render :partial => "module_form", :locals => { :app_module => app_module } %> <% end %> So if I have more than 1 item in the collection, I render the identical form on the same page, and the form id and textbox id are duplicated. I can customize the form id pretty easily, but what about the text_box, since the controller is looking for specific named controls?

So I have the next simple form for example: <asp:Content ID="_mainContent" ContentPlaceHolderID="MainContent" runat="server"> <script src="../../../Scripts/jquery-1.3.2.js" type="text/javascript"></script> <script src="../../../Scripts/jquery.validate.js" type="text/javascript"></script> <script type="text/javascript"> $(document).ready(function() { $("#aspnetForm").validate({ rules: { "<%= _txtProjectName.UniqueID %>": { required: true } } }); }); </script> <asp:TextBox ID="_txtProjectName" runat="server" CssClass="textBoxWithValidator_long" /> <entlib:PropertyProxyValidator id="_validatorProjectName" runat="server" ControlToValidate="_txtProjectName" PropertyName="ProjectName" SourceTypeName="LabManagement.Project.Project" /> <asp:Button CssClass="cell_InlineElement" ID="_btnSave" runat="server" Text="Save" onclick="_btnSave_Click" Width="50px" /> <asp:ScriptManager ID="ScriptManager1" runat="server" EnablePageMethods="true"> </asp:ScriptManager> </asp:Content> The problem is in the next: client-side validation worked correctly before I needed to implement some AJAX.NET feature. So I have to add to the page ScriptManager (the last two lines in the code). But after that the next situation appeared: In InternetExplorer((7) - only in IE !!! - in Firefox everything works correctly) after clicking save button, if left the textbox ProjectName empty the client-side jquery validation appears but (!) the page submits to the server anyway. Some notes: If delete PropertyProxyValidator from the page - the client-side validation works correctly in IE but I need it for specific of the project. It seems that the problem is in the function WebForm_OnSubmit() that is inserted to the form after PropertyProxyValidator adding. ( ... <form name="aspnetForm" method="post" action="Project.aspx?TransType=NewProject" onsubmit="javascript:return WebForm_OnSubmit();" ...>) Could anyone help, please.

• Is there a way to validates_presence_of only one time? (to skip that validation once the user's been

  - by GoodGets

  So, I'd like for a user to see an error message if he submits a comment and the :name is blank (typical error message, don't need help with that). However, I'd then like to allow the user to skip that validation once he's been notified that "we like all comments to have a name." So, he submits the comment once, sees the notification, then can submit the form again unchanged if he really doesn't want to add a name, and the validates_presences_of :name is skipped. But, I'm not sure how to go about doing this. I thought about checking to see where the request is coming from, but after a create, errors are handed off to the "new" action, which is the same as actual "new" comments. I then thought about checking to see if flash[errors] were present, but that won't work because there are other validations a comment has to pass. Finally, I thought about trying a validates_presences_of :name, :unless = :notified but wasn't sure how to define notified. I honestly hate asking such an open ended question, but wasn't sure where to get started. So, is there a way to just check a certain validation once?

• Submit form with POST data in Android app

  - by datguywhowanders

  I've been searching the web for a way to do this for about a week now, and I just can't seem to figure it out. I'm trying to implement an app that my college can use to allow users to log in to various services on the campus with ease. The way it works currently is they go to an online portal, select which service they want, fill in their user name and pwd, and click login. The form data is sent via post (it includes several hidden values as well as just the user name and pwd) to the corresponding login script which then signs them in and loads the service. I've been trying to come at the problem in two ways. I first tried a WebView, but it doesn't seem to want to support all of the html that normally makes this form work. I get all of the elements I need, fields for user and pwd as well as a login button, but clicking the button doesn't do anything. I wondered if I needed to add an onclick handler for it, but I can't see how as the button is implemented in the html of the webview not using a separate android element. The other possibility was using the xml widgets to create the form in a nice relative layout, which seems to load faster and looks better on the android screen. I used EditText fields for the input, a spinner widget for the service select, and the button widget for the login. I know how to make the onclick and item select handlers for the button and spinner, respectively, but I can't figure out how to send that data via POST in an intent that would then launch a browser. I can do an intent with the action url, but can't get the POST data to feed into it. Anyone have any suggestions?

• merging two small pieces of jquery codes

  - by Billa

  Following are two pieces of jquery code. First one prints a text message when clicked on a link, and the second slides down a div when click on a link. I want to merge second code into first one, so that when I click the link, it displays the message (as the first code does), and also slides down the #votebox (as done in second code, and show content in that. I will be very thankful for any help. $("a.vote_up").click(function(){ the_id = $(this).attr('id'); $("span#votes_count"+the_id).fadeOut("fast"); $.ajax({ type: "POST", data: "action=vote_up&id="+$(this).attr("id"), url: "votes.php", success: function(msg) { $("span#votes_up"+the_id).fadeOut(); $("span#votes_up"+the_id).html(msg); $("span#votes_up"+the_id).fadeIn(); //Here, I want to slide down the votebox and content div (from code below). } }); }); The following code slides down votebox div and displays content in it, I want to include that in the above code. $("a.vote_up").click(function(){ var id=$(this).attr("id"); var name=$(this).attr("name"); var dataString = 'id='+ id + '&name='+ name; //I want to include this votebox in above code. $("#votebox").slideDown("slow"); $("#flash").fadeIn("slow"); $.ajax({ type: "POST", url: "rating.php", data: dataString, cache: false, success: function(html){ $("#flash").fadeOut("slow"); //and want to use this div as well. $("#content").html(html); } }); }); Thanks for any help.

• UIButton receives touches at the wrong position after CABasicAnimaton applied

  - by Dmitry

  I need to add an animation to UIButton - simple moving animation. When I do this, the button moves, but the click area of that button remains at old position: UIButton *slideButton = [UIButton buttonWithType:UIButtonTypeRoundedRect]; [slideButton addTarget:self action:@selector(clicked:) forControlEvents:UIControlEventTouchUpInside]; [slideButton setFrame:CGRectMake(50, 50, 50, 50)]; [self.view addSubview:slideButton]; CABasicAnimation *slideAnimation = [CABasicAnimation animationWithKeyPath:@"position"]; [slideAnimation setRemovedOnCompletion:NO]; [slideAnimation setDuration:1]; [slideAnimation setFillMode:kCAFillModeBoth]; [slideAnimation setAutoreverses:NO]; slideAnimation.fromValue = [NSValue valueWithCGPoint:CGPointMake(50, 50)]; slideAnimation.toValue = [NSValue valueWithCGPoint:CGPointMake(100, 100)]; [slideButton.layer addAnimation:slideAnimation forKey:@"slide"]; I already saw an answer to change the frame of the button at the end of the animation (like here UIButton receives touchEvents at the wrong position after a CABasicAnimaton) But it's not my case because I should give possibility to user to click on the button while it's moving... Also, I can't use another approaches (like NSTimer) as a replacement for CABasicAnimation because I will have a complex path to move the object... Thanks for Your help!

• Work for huge company or small company that makes products for huge company?

  - by TheGambler

  I'm facing a career decision. I currently work for a huge, huge, huge company (this should bring 3-4 companies to mind) as a programmer. I work on a really big (3 million lines of code) J2EE web application. I've been out of college for 2 years and I pretty much know that big corporate life isn't for me. There is a career opportunity to work for a small company that has a lot of funding and huge potential to sell their main project to this huge company I work for.This company makes kiosk software and works with a nearby kiosk software company. The deal isn't done, but I would come straight in to work on this project. This would be more of a interactive media position and I would do the development in flash/action script. I personally think this will be more interesting work then what I do now. This company does have other clients right now, just not on the scale of this potential huge client. I was told that my initial salary would be equal to what I'm making now, but if we land this client it could go up a lot more. I have a wife and child which should and will play a part in my decision if I should take this job. We do though have family that if crap hit the fan we could live with until we got back on our feet. So with the information provided, does this sound like a good opportunity and should I take it? This is a huge decision and the reason I'm asking the question here is because there are a lot of people here that have probably faced this decision before.

• App hosting Report Viewer crashes on exit after export

  - by Paul Sasik

  We have a .NET Winforms application that hosts the Crystal Reports Viewer control (Version XI). It works well for the most part but when an export of data from the viewer is performed the application will crash on exit and in unmanaged code. The error message is not very useful and just says that an incorrect memory location was accessed. No other info such a specific DLL etc. is provided. This only happens after the viewer is used to export a report to CSV, XML etc. My guess is that at some point in the export process Crystal creates a resource that attempts an action on shut down to a parent window (perhaps) that no longer exists. I've seen a number of memory leak and shut down issues with Crystal but this one's new. Has anyone seen it and come up with a workaround or has ideas for workarounds? So far we've tried explicitly disposing of all crystal-related objects, setting to null and even setting a Thread.Sleep cycle on shut down to "give Crystal time to clean up." Update: The crash happens only on shut down (so not immediate) All export formats work All export files are created properly CR is installed on the same machine as the hosting .NET app not sure about exporting from the IDE... is that even possible?
