• dynamically change bitmap in imageView, android

  - by Junfei Wang

  All, I have a problem related to imageView, android. I have array which contains of 10 bitmap objects, called bm. I have a imageView, called im. Now I wanna show the bitmaps in the array in im one by one, so I did the following: new Thread(new Runnable() { public void run() { for(int j=0;j<10;j++){ im.setImageBitmap(bm[j]); } } }).start(); But the result only shows the last bitmap in the array. Can someone tell me what to do with this issue? Millions of thanks!

• Netbeans GUI editor problems

  - by RenegadeAndy

  Hey guys. Im making a portion of my app using the netbeans gui editor. Great so far. However ive added a new checkbox - and when i load the panel in my app the text attribute isnt shown...its just blank as if i have no caption on it... all the other ones display - so this is very annoying. It kind of seems that I have hit the limit on gui items or something, becasue any new items I add I cannot seem then, If i add new labels they dont show either :S! The other problems Im having are that the size of the window im editting appears to be fixed - every time i change it, it jumps back to the same size - how do i stop this from happening? Cheers Andy

• Checking date against date range in Python

  - by Flowpoke

  I have a date variable: 2011-01-15 and I would like to get a boolean back if said date is within 3 days from TODAY. Im not quite sure how to construct this in Python. Im only dealing with date, not datetime. My working example is a "grace period". A user logs into my site and if the grace period is within 3 days of today, additional scripts, etc. are omitted for that user. I know you can do some fancy/complex things in Python's date module(s) but Im not sure where to look.

• how to use use case relations - uml

  - by joao alves

  Heys guys! Im have been study UML and im trying to to design the use case diagram of a problem. Lets supose my app consists in this: Two Requesites: - create teams - create players This is the deal: A user can create a team, and after create a team he can create players for that team(not required). But in this app there are multiple users, and a user can create a team and other user can create players. The only constraint is that to create players must exist alreay a team. I research and i end up a little confuse. If i get the concepts of relations on use case diagrams right, i think i should have the folowwing two use cases: [use case - create team] <-------extends---- [use case - create player] I need opinions,Is this the proper solution? or should i have two not related use cases? Thanks in advance, and im sorry my english.

• Hibernate, alter identifier/primary key

  - by Schildmeijer

  I receive the following exception when Im trying to alter my @ID in an @Entity. identifier of an instance of com.google.search.pagerank.ItemEntity was altered from 1 to 2. I know that im altering the primary key in my table. Im using JPA-annotations. I solved this by using this single HQL query: update Table set name=:newName where name=:oldName instead of using the more oo approach: beginTransaction(); T e = session.load(...); e.setName(newName); session.saveOrUdate(e); commit(); Any idea what the diff is?

• Simplest way to extend doctrine for MVC Models

  - by RobertPitt

  Im developing my own framework that uses namespaces. Doctrine is already integrated into my auto loading system and im now at the stage where ill be creating the model system for my application Usually i would create a simple model like so: namespace Application\Models; class Users extends \Framework\Models\Database{} which would inherit all the default database model methods, But with Doctrine im still learning how it all works, as its not just a simple DBAL. I need to understand whats the part of doctrine my classes would extend where i can do the following: namespace Application\Models; class Users Extends Doctrine\Something\Table { public $__table_name = "users"; } And thus within the controller i would be able to do the following: public function Display($uid) { $User = $this->Model->Users->findOne(array("id" => (int)$id)); } Anyone help me get my head around this ?

• Javascript pass reference by value

  - by Carlos R. Batista

  Im having this weird reference issue when im trying to get a JSON file through query: var themeData; $.getJSON("json/sample.js", function(data) { themeData = data.theme; console.log(themeData.sample[0].description); }); console.log(themeData.sample[0].description); The first console.log works, the second doesnt. Im guessing because "data" already expired by the time the script gets there and themeData is just a mere pointer to "data". Is there a ways I can make sure themeData gets a duplicate of "data" and not just a pointer to it?

  - by Truegilly

  Hello, im creating a MVC application thats following a restfull URL approach Im am experiencing the following error... "The specified path, file name, or both are too long. The fully qualified file name must be less than 260 characters, and the directory name must be less than 248 characters." This error occurs when my URL length = 225 chars.

• XML Processing on iPhone: What is the best option?

  - by gonso

  Hello Im building a new version of an iPhone application and Im wondering if I should review how my app communicates with the server. My iPhone client sends and receives XML over HTTP requests. To send the information I use ASIHTTPRequest framework. I "manually" build the XML request by appending strings. To parse the response Im using a NSXMLParser. My question is if I have better options to A) Create an XML string from a memory object. B) Create a memory object from the XML string. Is there anything like JAXB to marshal XML into object? Thanks Gonso

• 3d movement around a sphere

  - by user578954

  Hey guys, Im working in 3d for the first time in a long time. Basically im rotating a sphere and projecting x y z cords to place things on the surface based on the spheres X and Y rotation. Heres the code im using: #define piover180 0.01745329252f GLfloat cosy = cos(yrot * piover180); island[i].x = rad * sin(xrot * piover180)* cosy; island[i].y = rad * sin(yrot * piover180); island[i].z = rad * cos(xrot * piover180) * cosy; Problem is the Xrot positioning works fine but the Yrot placement always draw the objects into the north and south pole so they all cross at the top, which isnt correct for rotating. I need a way to solve this. Heres a picture to help explain http://llllost.com/shuttle/47bcde62.jpg Any help would be greatly appreciated, let me know if you need any more information

• Multi dimensional array with get image data

  - by Dave

  I'm really confused with an array im making, its gotten a bit confusing to follow but i believe its the only way for me to approach what im trying to do. My idea here is to store getImageData in an array so i can link each image to an array of data. This is how i create my array: var listObj = { id: uid, extra: [ ctx2.getImageData(abposx,abposy,imgwidth,imgheight) ] }; pixeld.push(listObj); So now im trying to run through the array "pixeld" to find the uid but i don't know how the syntax should be.... this is what i tried: for (j = (pixeld.length-1); j > -1; --j){ if(pixeld[j].extra.data[3] !==0){ //line 220 matches.push(pixeld[j].id); } } The problem is i get this error: Uncaught TypeError: Cannot read property '3' of undefined on line 220 I have marked which line is 220 in the for loop. Any one know what my mistake is ?
