• How to override a method for a MovieClip Symbol in Flash CS3

  - by php html

  I'm using flash to draw objects, then I export them and use them from flex, and I'm a beginner in flash. I'm trying to do the override a method from the MovieClip I created. The method I'm trying to override is stop() method. I didn't write a single line of code, my movie clip is created using entirely the flash interface. I figured out how to add actions to the movie clip when a frame is reached but I'm stucked now when I'm trying to override a MovieClip method.

• Changing UIImageView animation speed

  - by Nikolas Stephan

  I am using the UIImageView to animate a bunch of images. I know that I can change the speed by altering animationDuration, but that doesn't seem to take effect until the animation is restarted. My problem is that beside not really wanting to have to restart the animation as this limits me to only being able to change the speed once per cycle, there also doesn't seem to be a way to find out what frame is currently being shown and I would therefore have to rely on a timer to "guess" which one it is. So my question is whether there is a way to change the speed without restarting the animation and if not is there some way I could avoid the aforementioned problem? I'm not too keen to write my own animation class, but may end up having to if there isn't a nicer solution.

• UIButton on UIScrollView can't work

  - by william-hu

  Hi, i used UILabel *myLabel = [[UILabel alloc] initWithFrame:CGRectMake(10, 10, 180, 180)]; myLabel.backgroundColor = [UIColor greenColor]; [self.view addSubview:myLabel]; UIButton *myButton = [UIButton buttonWithType:UIButtonTypeRoundedRect]; [self addTarget:self action:@selector(show) forControlEvents:UIControlEventTouchDown]; myButton.frame = CGRectMake(80.0, 120.0, 30, 30); myButton.showsTouchWhenHighlighted = YES; [self addSubview:myButton]; in this way the button works(call show:), but use [myLabel addSubview:myButton]; the button can't work. who can tell me why?

• UIScrollView won't autorotate

  - by clozach

  My app design requires the same scrolling functionality found in the iPhone's native Photos app when browsing photos in full screen. Specifically: Each view snaps into place as the view is swiped Scrolling happens in only one direction Rotating the iPhone rotates the entire scrolling region as well such that the frame of each subview (photos, in Apple's case) rotates in-place and paging is still in the same direction (left-to-right) I started to use Apple's sample PageControl code as a launching point, and everything was going swimmingly until I attempted adding autorotation to the code. My sense from the docs was that all I had to do to get autorotation working was to add this to the sample code's MyViewController.m - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return YES; } While that does seem to cause the subviews' backgrounds to rotate, the UILabels and the enclosing UIScrollView stay fixed so that, from a user perspective, paging through the views now requires up/down flicking instead of left/right.

• Using UpdatePanels inside of a ListView

  - by Jim B

  Hey everyone, I'm wondering if anybody has run across something similar to this before. Some quick pseudo-code to get started: <UpdatePanel> <ContentTemplate> <ListView> <LayoutTemplate> <UpdatePanel> <ContentTemplate> <ItemPlaceholder /> </ContentTemplate> </UpdatePanel> </LayoutTemplate> <ItemTemplate> Some stuff goes here </ItemTemplate> </ListView> </ContentTemplate> </UpdatePanel> The main thing to take away from the above is that I have an update panel which contains a listview; and then each of the listview items is contained in its own update panel. What I'm trying to do is when one of the ListView update panels triggers a postback, I'd want to also update one of the other ListView item update panels. A practical implementation would be a quick survey, that has 3 questions. We'd only ask Question #3 if the user answered "Yes" to Question #1. When the page loads; it hides Q3 because it doesn't see "Yes" for Q1. When the user clicks "Yes" to Q1, I want to refresh the Q3 update panel so it now displays. I've got it working now by refreshing the outer UpdatePanel on postback, but this seems inefficient because I don't need to re-evaluate every item; just the ones that would be affected by the prerequisite i detailed out above. I've been grappling with setting up triggers, but i keep coming up empty mainly because I can't figure out a way to set up a trigger for the updatepanel for Q3 based off of the postback triggered by Q1. Any suggestions out there? Am I barking up the wrong tree?

• How to add a view on top of a UIPopoverController

  - by Noah Witherspoon

  I've got an iPad app with a “drawer” table displayed in a popover. The user can tap-and-hold on an item in the drawer to drag that item out of it and into my main view. That part works fine; unfortunately, the view being dragged appears under the popover, and is too small to be visible until it's dragged out from underneath it. If I add the view as a subview of the view controller in the popover, it gets clipped by the popover's frame, and as I can't access the UIPopoverController's view, I can't disable its layer's masksToBounds—and that probably wouldn't be a great idea anyway. I suspect that I could use an additional UIWindow with a high windowLevel value to force the dragged view to appear on top of the popover, but this seems like overkill. Is there a better solution?

• Help with JPQL query

  - by Robert

  I have to query a Message that is in a provided list of Groups and has not been Deactivated by the current user. Here is some pseudo code to illustrate the properties and entities: class Message { private int messageId; private String messageText; } class Group { private String groupId; private int messageId; } class Deactivated { private String userId; private int messageId; } Here is an idea of what I need to query for, it's the last AND clause that I don't know how to do (I made up the compound NOT IN expression). Filtering the deactivated messages by userId can result in multiple messageIds, how can I check if that subset of rows does not contain the messageId? SELECT msg FROM Message msg, Group group, Deactivated unactive WHERE group.messageId = msg.messageId AND (group.groupId = 'groupA' OR group.groupId = 'groupB' OR ...) AND ('someUserId', msg.messageId) NOT IN (unactive.userId, unactive.messageId) I don't know the number of groupIds ahead of time -- I receive them as a Collection<String> so I'll need to traverse them and add them to the JPQL dynamically.

• Get signal names from numbers in Python

  - by Brian M. Hunt

  Is there a way to map a signal number (e.g. signal.SIGINT) to its respective name (i.e. "SIGINT")? I'd like to be able to print the name of a signal in the log when I receive it, however I cannot find a map from signal numbers to names in Python, i.e. import signal def signal_handler(signum, frame): logging.debug("Received signal (%s)" % sig_names[signum]) signal.signal(signal.SIGINT, signal_handler) For some dictionary sig_names, so when the process receives SIGINT it prints: Received signal (SIGINT) Thank you.

• setSearchDisplayController considered private-API?

  - by Adun

  Hi, I recently submitted an app for app review but I got rejected because of the use of a private API. I'm still a bit new to iPhone developing so I was wondering if someone could help me understand how this part was rejected: UISearchBar *searchBar = [[[UISearchBar alloc] initWithFrame:CGRectMake(0, 0, self.tableView.frame.size.width, 0)] autorelease]; searchBar.showsCancelButton = NO; searchBar.placeholder = @"Search Exhibitors"; [searchBar sizeToFit]; [self.tableView setTableHeaderView:searchBar]; UISearchDisplayController *searchDisplayController = [[UISearchDisplayController alloc] initWithSearchBar:searchBar contentsController:self]; [self performSelector:@selector(setSearchDisplayController:) withObject:searchDisplayController]; [searchDisplayController setDelegate:self]; [searchDisplayController setSearchResultsDataSource:self]; [searchDisplayController setSearchResultsDelegate:self]; [searchDisplayController release]; The part that they mentioned was the "setSearchDisplayController". I based the searching of a UITableView on the example given here. So can anyone explain why this is considered a private API?

• Get special numbers from a random number generator

  - by Wikeno

  I have a random number generator: int32_t ksp_random_table[GENERATOR_DEG] = { -1726662223, 379960547, 1735697613, 1040273694, 1313901226, 1627687941, -179304937, -2073333483, 1780058412, -1989503057, -615974602, 344556628, 939512070, -1249116260, 1507946756, -812545463, 154635395, 1388815473, -1926676823, 525320961, -1009028674, 968117788, -123449607, 1284210865, 435012392, -2017506339, -911064859, -370259173, 1132637927, 1398500161, -205601318, }; int front_pointer=3, rear_pointer=0; int32_t ksp_rand() { int32_t result; ksp_random_table[ front_pointer ] += ksp_random_table[ rear_pointer ]; result = ( ksp_random_table[ front_pointer ] >> 1 ) & 0x7fffffff; front_pointer++, rear_pointer++; if (front_pointer >= GENERATOR_DEG) front_pointer = 0; if (rear_pointer >= GENERATOR_DEG) rear_pointer = 0; return result; } void ksp_srand(unsigned int seed) { int32_t i, dst=0, kc=GENERATOR_DEG, word, hi, lo; word = ksp_random_table[0] = (seed==0) ? 1 : seed; for (i = 1; i < kc; ++i) { hi = word / 127773, lo = word % 127773; word = 16807 * lo - 2836 * hi; if (word < 0) word += 2147483647; ksp_random_table[++dst] = word; } front_pointer=3, rear_pointer=0; kc *= 10; while (--kc >= 0) ksp_rand(); } I'd like know what type of pseudo random number generation algorithm this is. My guess is a multiple linear congruential generator. And is there a way of seeding this algorithm so that after 987721(1043*947) numbers it would return 15 either even-only, odd-only or alternating odd and even numbers? It is a part of an assignment for a long term competition and i've got no idea how to solve it. I don't want the final solution, I'd like to learn how to do it myself.

• PyQt and unittest - how to handle signals and slots

  - by Einar

  Hello, some small application I'm developing uses a module I have written to check certain web services via a REST API. I've been trying to add unit tests to it so I don't break stuff, and I stumbled upon a problem. I use a lot of signal-slot connections to perform operations asynchronously. For example a typical test would be (pseudo-Python), with postDataDownloaded as a signal: def testConnection(self): "Test connection and posts retrieved" def length_test(): self.assertEqual(len(self.client.post_data), 5) self.client.postDataReady.connect(length_test) self.client.get_post_list(limit=5) Now, unittest will report this test to be "ok" when running, regardless of the result (as another slot is being called), even if asserts fail (I will get an unhandled AssertionError). Example when deliberatiely making the test fail: Test connection and posts retrieved ... ok [... more tests...] OK Traceback (most recent call last): [...] AssertionError: 4 != 5 The slot inside the test is merely an experiment: I get the same results if it's outside (instance method). I also have to add that the various methods I'm calling all make HTTP requests, which means they take a bit of time (I need to mock the request - in the mean time I'm using SimpleHTTPServer to fake the connections and give them proper data). Is there a way around this problem?

• JQuery ajax request returns error and status 0

  - by Kucebe

  I use this pseudo-class to make ajax request to server: function RequestManager(url, params, success, error){ //save this ajax configuration this._ajaxCall = null; this._url= url; this._type = params.type; this._timer = params.timer || 0; this._success = function(){ alert("ok"); }; this._error = function(){ alert("ko"); }; } RequestManager.prototype = { require : function(tag){//here there will be a tag object in array format if(this.timer>0){ //wait this.timer } if(this.ajaxCall != null ){ this.ajaxCall.abort(); this.ajaxCall = null; } var self = this; this.ajaxCall = $.ajax({ url: this._url, type: this._type, data: tag, success: function(xmlResponse){ var responseArray = []; var response = _extractElements(xmlResponse, arrayResponse); self._success(response); }, error: self._error, complete : function(xhr, statusText){ alert(xhr.status); return null; } }); } When i instantiate a new object, and i use it to load a request, it always return to me error, and status code is 0. Server correctly generates an xml document. Why i can't get a correct 200 code back?

• Thread resource sharing

  - by David

  I'm struggling with multi-threaded programming... I have an application that talks to an external device via a CAN to USB module. I've got the application talking on the CAN bus just fine, but there is a requirement for the application to transmit a "heartbeat" message every second. This sounds like a perfect time to use threads, so I created a thread that wakes up every second and sends the heartbeat. The problem I'm having is sharing the CAN bus interface. The heartbeat must only be sent when the bus is idle. How do I share the resource? Here is pseudo code showing what I have so far: TMainThread { Init: CanBusApi =new TCanBusApi; MutexMain =CreateMutex( "CanBusApiMutexName" ); HeartbeatThread =new THeartbeatThread( CanBusApi ); Execution: WaitForSingleObject( MutexMain ); CanBusApi->DoSomething(); ReleaseMutex( MutexMain ); } THeartbeatThread( CanBusApi ) { Init: MutexHeart =CreateMutex( "CanBusApiMutexName" ); Execution: Sleep( 1000 ); WaitForSingleObject( MutexHeart ); CanBusApi->DoHeartBeat(); ReleaseMutex( MutexHeart ); } The problem I'm seeing is that when DoHeartBeat is called, it causes the main thread to block while waiting for MutexMain as expected, but DoHeartBeat also stops. DoHeartBeat doesn't complete until after WaitForSingleObject(MutexMain) times out in failure. Does DoHeartBeat execute in the context of the MainThread or HeartBeatThread? It seems to be executing in MainThread. What am I doing wrong? Is there a better way? Thanks, David

• How do I use a .NET class in VBA? Syntax help!

  - by Jordan S

  ok I have couple of .NET classes that I want to use in VBA. So I must register them through COM and all that. I think I have the COM registration figured out (finally) but now I need help with the syntax of how to create the objects. Here is some pseudo code showing what I am trying to do. EDIT: Changed Attached Objects to return an ArrayList instead of a List The .NET classes look like this... public class ResourceManagment { public ResourceManagment() { // Default Constructor } public static List<RandomObject> AttachedObjects() { ArrayList list = new ArrayList(); return list; } } public class RandomObject { // public RandomObject(int someParam) { } } OK, so this is what I would like to do in VBA (demonstrated in C#) but I don't know how... public class VBAClass { public void main() { ArrayList myList = ResourceManagment.AttachedObjects(); foreach(RandomObject x in myList) { // Do something with RandomObject x like list them in a Combobox } } } One thing to note is that RandomObject does not have a public default constructor. So I can not create an instance of it like Dim x As New RandomObject. MSDN says that you can not instantiate an object that doesn't have a default constructor through COM but you can still use the object type if it is returned by another method... Types must have a public default constructor to be instantiated through COM. Managed, public types are visible to COM. However, without a public default constructor (a constructor without arguments), COM clients cannot create an instance of the type. COM clients can still use the type if the type is instantiated in another way and the instance is returned to the COM client. You may include overloaded constructors that accept varying arguments for these types. However, constructors that accept arguments may only be called from managed (.NET) code. Added: Here is my attempt in VB: Dim count As Integer count = 0 Dim myObj As New ResourceManagment For Each RandomObject In myObj.AttachedObjects count = count + 1 Next RandomObject

• Looking for a lock-free RT-safe single-reader single-writer structure

  - by moala

  Hi, I'm looking for a lock-free design conforming to these requisites: a single writer writes into a structure and a single reader reads from this structure (this structure exists already and is safe for simultaneous read/write) but at some time, the structure needs to be changed by the writer, which then initialises, switches and writes into a new structure (of the same type but with new content) and at the next time the reader reads, it switches to this new structure (if the writer multiply switches to a new lock-free structure, the reader discards these structures, ignoring their data). The structures must be reused, i.e. no heap memory allocation/free is allowed during write/read/switch operation, for RT purposes. I have currently implemented a ringbuffer containing multiple instances of these structures; but this implementation suffers from the fact that when the writer has used all the structures present in the ringbuffer, there is no more place to change from structure... But the rest of the ringbuffer contains some data which don't have to be read by the reader but can't be re-used by the writer. As a consequence, the ringbuffer does not fit this purpose. Any idea (name or pseudo-implementation) of a lock-free design? Thanks for having considered this problem.

• Move a legend in ggplot2

  - by Dan Goldstein

  I'm trying to create a ggplot2 plot with the legend beneath the plot. The ggplot2 book says on p 112 "The position and justification of legends are controlled by the theme setting legend.position, and the value can be right, left, top, bottom, none (no legend), or a numeric position". The following code works (since "right" it is the default), and it also works with "none" as the legend position, but "left", "top", "bottom", all fail with "Error in grid.Call.graphics("L_setviewport", pvp, TRUE) : Non-finite location and/or size for viewport" library(ggplot2) (myDat <- data.frame(cbind(VarX=10:1, VarY=runif(10)), Descrip=sample(LETTERS[1:3], 10, replace=TRUE))) qplot(VarX,VarY, data=myDat, shape=Descrip) + opts(legend.position="right") What am I doing wrong? Re-positioning a legend must be incredibly common, so I figure it's me.

• Complex data types in WCF?

  - by Hojou

  I've run into a problem trying to return an object that holds a collection of childobjects that again can hold a collection of grandchild objects. I get an error, 'connection forcibly closed by host'. Is there any way to make this work? I currently have a structure resembling this: pseudo code: Person: IEnumerable<Order> Order: IEnumberable<OrderLine> All three objects have the DataContract attribute and all public properties i want exposed (including the IEnumerable's) have the DataMember attribute. I have multiple OperationContract's on my service and all the methods returning a single object OR an IEnumerable of an object works perfectly. It's only when i try to nest IEnumerable that it turns bad. Also in my client service reference i picked the generic list as my collection type. I just want to emphasize, only one of my operations/methods fail with this error - the rest of them work perfectly. EDIT (more detailed error description): [SocketException (0x2746): An existing connection was forcibly closed by the remote host] [IOException: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.] [WebException: The underlying connection was closed: An unexpected error occurred on a receive.] [CommunicationException: An error occurred while receiving the HTTP response to http://myservice.mydomain.dk/MyService.svc. This could be due to the service endpoint binding not using the HTTP protocol. This could also be due to an HTTP request context being aborted by the server (possibly due to the service shutting down). See server logs for more details.] I tried looking for logs but i can't find any... also i'm using a WSHttpBinding and an http endpoint.

• glTexImage2D behavior on iPhone and other OpenGL ES platforms

  - by spurserh

  Hello, I am doing some work which involves drawing video frames in real time in OpenGL ES. Right now I am using glTexImage2D to transfer the data, in the absence of Pixel Buffer Objects and the like. I suspect that the use of glTexImage2D with one or two frames of look-ahead, that is, using several textures so that the glTexImage2D call can be initiated a frame or two ahead, will allow for sufficient parallelism to play in real time if the system is capable of it at all. Is my assumption true that the driver will handle the actual data transfer to the hardware asynchronously after glTexImage2D returns, assuming I don't try to use the texture or call glFinish/glFlush? Is there a better way to do this with OpenGL ES? Thank you very much, Sean

• How to set a Transparent Background of JPanel

  - by Imran

  Hi, I need to know if a JPanel`s bacground can be set to Transparent? My frame is has two Jpanels Image Panel and Feature Panel, Feature Panel is overlapping Image Panel, the Image Panel is working as a background and it is loading image from a remote Url, now I want to draw shaps on Feature Panel , but now Image Panel cannot be seen due to Feature Panel's background color. I need to make Feature Panel background transparent while still drawing its shapes and i want Image Panel to be visible since it is doing tiling and cache function of images. I need to seperate the image drawing and shape drawing thats why I`m using two jPanels! is there anyway the overlapping Jpanel have a transparent background? thanks

• Repairing malformatted html attributes using c#

  - by jhoefnagels

  I have a web application with an upload functionality for HTML files generated by chess software to be able to include a javascript player that reproduces a chess game. I do not like to load the uploaded files in a frame so I reconstruct the HTML and javascript generated by the software by parsing the dynamic parts of the file. The problem with the HTML is that all attributes values are surrounded with an apostrophe instead of a quotation mark. I am looking for a way to fix this using a library or a regex replace using c#. The html looks like this: <DIV class='pgb'><TABLE class='pgbb' CELLSPACING='0' CELLPADDING='0'><TR><TD> and I would transform it into: <DIV class="pgb"><TABLE class="pgbb" CELLSPACING="0" CELLPADDING="0"><TR><TD>

• Back button loop with IFRAMES

  - by Tim Jackson

  In my (school) website we use Iframes to display class blogs (on blogger). This works well EXCEPT if the user then clicks on (say) a photo inside the iframe. Blogger (in this case) then displays the photo in the whole browser window and the back button loops; that is if the back button is hit, the browser (IE, FF, Chrome) stays on the same page. The only way out is for the user to jump back two pages (which many of our users don't know how to do). I've read a lot of posts on back buttons and iframes and there doesn't appear to be a simple solution. Bear in mind that I don't have control over the iframe content (so no embedded back buttons in the frame are possible). Ideas anyone?

• MySQL Unique hash insertion

  - by Jesse

  So, imagine a mysql table with a few simple columns, an auto increment, and a hash (varchar, UNIQUE). Is it possible to give mysql a query that will add a column, and generate a unique hash without multiple queries? Currently, the only way I can think of to achieve this is with a while, which I worry would become more and more processor intensive the more entries were in the db. Here's some pseudo-php, obviously untested, but gets the general idea across: while(!query("INSERT INTO table (hash) VALUES (".generate_hash().");")){ //found conflict, try again. } In the above example, the hash column would be UNIQUE, and so the query would fail. The problem is, say there's 500,000 entries in the db and I'm working off of a base36 hash generator, with 4 characters. The likelyhood of a conflict would be almost 1 in 3, and I definitely can't be running 160,000 queries. In fact, any more than 5 I would consider unacceptable. So, can I do this with pure SQL? I would need to generate a base62, 6 char string (like: "j8Du7X", chars a-z, A-Z, and 0-9), and either update the last_insert_id with it, or even better, generate it during the insert. I can handle basic CRUD with MySQL, but even JOINs are a little outside of my MySQL comfort zone, so excuse my ignorance if this is cake. Any ideas? I'd prefer to use either pure MySQL or PHP & MySQL, but hell, if another language can get this done cleanly, I'd build a script and AJAX it too. Thanks!

• LaTeX beamer free-flowing two column?

  - by anon

  So in standard LaTeX, there is \twocolumn, where I can just type text, and it'll go down the left side of the page, then continue at the top of the right side of the page. Now, I know that inside of a Beamer frame, I can manually create two columns, of various width, with text in them -- however, is there a way to have the text freely flow from one column to the next? [I.e. I want to say "this text goes in these two columns; and have beamer figure out which goes into which column]. Thanks!
