  • In Android OS or Java, what's the difference between a character sequence and a string????

    - by K-RAN
    For the API (Android SDK API version 8) functions whose definitions list character sequence parameters, I can feed the function String instead. Best part is that they work the same way, no hassle, no warnings. Is there a difference between the two types? And more importantly, is there an inherent danger if I send the function a String instead of a character sequence??? Thanks for any clarifications!!! :D

    - by Meta
    Looking at the Windows SDK, I found this #define directive for MAKEINTRESOURCEW: #define MAKEINTRESOURCEW(i) ((LPWSTR)((ULONG_PTR)((WORD)(i)))) Can someone explain to me what the heck that means? For example, what would be the value of MAKEINTRESOURCEW(0)? (1)? (-1)?

  • Xcode: iPhone screenshots no longer work

    - by Chris Newman
    I can't be sure when this stopped working because I haven't used it for a while, but it was possibly since I upgraded to the 3.2 SDK. In Organizer, when I select the "Screenshots" tab and press "Capture", nothing happens. I've tried this with three different devices and I've restarted my Mac. What's happened, and how can I fix it?

  • ipod app replacement-in-a-tab?

    - by Frank C
    With the new media-library capabilities in the 3.0 SDK, I'd like to have a tab in my application to control the music that's playing. Not just pause and play (i'm aware that pressing the home button twice brings up controls for this), but also the ability to browse and queue albums/artists/songs/playlists. Basically a copy of the ipod app functionality. Any chance someone has already done this and made it freely available?

  • Reattaching an object graph to an EntityContext: "cannot track multiple objects with the same key"

    - by dkr88
    Can EF really be this bad? Maybe... Let's say I have a fully loaded, disconnected object graph that looks like this: myReport = {Report} {ReportEdit {User: "JohnDoe"}} {ReportEdit {User: "JohnDoe"}} Basically a report with 2 edits that were done by the same user. And then I do this: EntityContext.Attach(myReport); InvalidOperationException: An object with the same key already exists in the ObjectStateManager. The ObjectStateManager cannot track multiple objects with the same key. Why? Because the EF is trying to attach the {User: "JohnDoe"} entity TWICE. This will work: myReport = {Report} {ReportEdit {User: "JohnDoe"}} EntityContext.Attach(myReport); No problems here because the {User: "JohnDoe"} entity only appears in the object graph once. What's more, since you can't control how the EF attaches an entity, there is no way to stop it from attaching the entire object graph. So really if you want to reattach a complex entity that contains more than one reference to the same entity... well, good luck. At least that's how it looks to me. Any comments? UPDATE: Added sample code: // Load the report Report theReport; using (var context1 = new TestEntities()) { context1.Reports.MergeOption = MergeOption.NoTracking; theReport = (from r in context1.Reports.Include("ReportEdits.User") where r.Id == reportId select r).First(); } // theReport looks like this: // {Report[Id=1]} // {ReportEdit[Id=1] {User[Id=1,Name="John Doe"]} // {ReportEdit[Id=2] {User[Id=1,Name="John Doe"]} // Try to re-attach the report object graph using (var context2 = new TestEntities()) { context2.Attach(theReport); // InvalidOperationException }

  • Having trouble with instantiating objects in PHP & Ajax custom shopping cart

    - by Phil
    This is my first time playing with both ajax and objects, so please go easy on me I have 3 pages that make up the tester shopping cart. 1) page with 'add' 'remove' buttons and ajax code to call the PHP functions on page 2. this is the actual user page with the HTML output. 2) page with PHP cart function calls, receives $_GET requests from ajax on page 1 and calls functions of the cart object from page 3, returns results to page 1. 3) page with cart object definition. Here's the problem I believe I'm having. Currently I have 'session_start()' on pgs 1 & 2, and the cart definition (pag 3) on pgs 1 & 2. I only define '$_SESSION[cart]= new Cart' on page 2. However, it seems like each time i hit an ajax function (eg each time pg 2 reloads) it seems like it's rewriting $_SESSION['cart'] over again, thus it's always empty at each new click (even tho it displays results of that click) However, if i don't define '$_SESSION[cart] = new Cart' on pg 2, i get an error: Fatal error: main() [function.main]: The script tried to execute a method or access a property of an incomplete object. Please ensure that the class definition "Cart" of the object you are trying to operate on was loaded before unserialize() gets called or provide a __autoload() function to load the class definition in /home3/foundloc/public_html/booka/carti.php on line 17 Any suggestions? How can i stop re-creating my cart each time my page 2 (php cart function page) is called by ajax?

  • MVC Multiple submit buttons on a array of objects

    - by Kieron
    Hi, I've got a list of objects in an MVC view, each with a set of submit buttons - Move up, Move down and Remove. Using the answer from this question, I can get the button clicked - but I need to know which item it would be operating on. The problem comes from the fact the input's value attribute is passed back, I need more information than that - i.e. an id. Below is a snippet of the contents of a for loop, rendering each item. <ul> <li><input type="submit" name="SubmitButton" value="Move-Up" class="linked-content-position-modifier" /></li> <li><input type="submit" name="SubmitButton" value="Move-Down" class="linked-content-position-modifier" /></li> <li><input type="submit" name="SubmitButton" value="Remove" class="linked-content-modifier" /></li> <li><%= Model.Contents[i] %></li> </ul> When the form is posted back, I can see that the SubmitButton has a value of either Move-Up, Move-Down or Remove - but no idea which item in the array it's referring too. Without changing the value to something really ugly, how would I tell which item it's referring to?
