  • Is single float assignment an atomic operation on the iPhone?

    - by iter
    I assume that on a 32-bit device like the iPhone, assigning a short float is an atomic, thread-safe operation. I want to make sure it is. I have a C function that I want to call from an Objective-C thread, and I don't want to acquire a lock before calling it: void setFloatValue(float value) { globalFloat = value; }

  • iOS Application Background Downloading

    - by Hankweb
    Hey! I need to know how I can have my iOS Application start a download in the background of the application (like, have the download run in the AppDelegate file) so changing ViewControllers will not interrupt or cancel the download. I also need to be able to get the progress of the download (0.00000 - 1.00000), to set a UIProgressView object to, which also means I need a - (void)progressDidChangeTo:(int)progress function.

  • Flash AS3 button eventlistener array bug

    - by Tyler Pepper
    Hi there, this is my first time posting a question here. I have an array of 12 buttons on a timeline that when first visiting that part of the timeline, get a CLICK eventlistener added to them using a for loop. All of them work perfectly at that point. When you click one it plays a frame label inside the specific movieClip and reveals a bio on the corresponding person with a close button and removes the CLICK eventlisteners for each button, again using a for loop. The close button plays a closing animation, and then the timeline goes back to the first frame (the one with the 12 buttons on it) and the CLICK eventlisteners are re-added, but now only the first 9 buttons of the array work. There are no output errors and the code to re-add the eventlisteners is exactly the same as the first time that works. I am completely at a loss and am wondering if anyone else has run into this problem. All of my buttons are named correctly, there are absolutely no output errors (I've used the debug module) and I made sure the array with the buttons in it is outputting all 12 at the moment the close button is clicked to add the eventlisteners back. for (var q = 0; q < ackBoDBtnArray.length; q++){ contentArea_mc.acknowledgements_mc.BoD_mc[ackBoDBtnArray[q]].addEventListener(MouseEvent.CLICK, showBio); } private function showBio(eo:MouseEvent):void { trace("show the bio"); bodVar = ackBoDBtnArray.getIndex(eo.target.name); contentArea_mc.acknowledgements_mc.BoD_mc.gotoAndPlay(ackBoDPgArray[bodVar]); contentArea_mc.acknowledgements_mc.BoD_mc.closeBio_btn.addEventListener(MouseEvent.CLICK, hideBio); for (var r = 0; r < ackBoDBtnArray.length; r++){ contentArea_mc.acknowledgements_mc.BoD_mc[ackBoDBtnArray[r]].mouseEnabled = false; contentArea_mc.acknowledgements_mc.BoD_mc[ackBoDBtnArray[r]].removeEventListener(MouseEvent.CLICK, showBio); } } private function hideBio(eo:MouseEvent):void { trace("hide it!"); contentArea_mc.acknowledgements_mc.BoD_mc.closeBio_btn.removeEventListener(MouseEvent.CLICK, hideBio); contentArea_mc.acknowledgements_mc.BoD_mc.gotoAndPlay(ackBoDClosePgArray[bodVar]); for (var s = 0; s < ackBoDBtnArray.length; s++){ trace(ackBoDBtnArray[s]); contentArea_mc.acknowledgements_mc.BoD_mc[ackBoDBtnArray[s]].mouseEnabled = true; contentArea_mc.acknowledgements_mc.BoD_mc[ackBoDBtnArray[s]].addEventListener(MouseEvent.CLICK, showBio); } Thanks in advance for any help and insight you can provide...I have a slight feeling that its something that may be obvious to another set of eyes...haha.

  • How do I tell ReSharper that an attribute means that a method is used?

  • TimePickerDialog and AM or PM

    - by martinjd
    I have a TimePickerDialog with is24Hour set to false since I want to present the end-user with the more familiar 12 hour format. When the hour, minute and AM PM indicator are set and the time is returned how can I identify whether the end-user has selected AM or PM? This is what I have for the listener: private TimePickerDialog.OnTimeSetListener mTimeSetListener = new TimePickerDialog.OnTimeSetListener() { @Override public void onTimeSet(TimePicker view, int hourOfDay, int minute) { mHour = hourOfDay; mMinute = minute; // mIsAM = WHERE CAN I GET THIS VALUE } };

  • Validate an Xml file against a DTD with a proxy. C# 2.0

    - by Chris Dunaway
    I have looked at many examples for validating an XML file against a DTD, but have not found one that allows me to use a proxy. I have a cXml file as follows (abbreviated for display) which I wish to validate: <?xml version="1.0" encoding="utf-8"?> <!DOCTYPE cXML SYSTEM "http://xml.cxml.org/schemas/cXML/1.2.018/InvoiceDetail.dtd"> <cXML payloadID="123456" timestamp="2009-12-10T10:05:30-06:00"> <!-- content snipped --> </cXML> I am trying to create a simple C# program to validate the xml against the DTD. I have tried code such as the following but cannot figure out how to get it to use a proxy: private static bool isValid = false; static void Main(string[] args) { try { XmlTextReader r = new XmlTextReader(args[0]); XmlReaderSettings settings = new XmlReaderSettings(); XmlDocument doc = new XmlDocument(); settings.ProhibitDtd = false; settings.ValidationType = ValidationType.DTD; settings.ValidationEventHandler += new ValidationEventHandler(v_ValidationEventHandler); XmlReader validator = XmlReader.Create(r, settings); while (validator.Read()) ; validator.Close(); // Check whether the document is valid or invalid. if (isValid) Console.WriteLine("Document is valid"); else Console.WriteLine("Document is invalid"); } catch (Exception ex) { Console.WriteLine(ex.ToString()); } } static void v_ValidationEventHandler(object sender, ValidationEventArgs e) { isValid = false; Console.WriteLine("Validation event\n" + e.Message); } The exception I receive is System.Net.WebException: The remote server returned an error: (407) Proxy Authentication Required. which occurs on the line while (validator.Read()) ; I know I can validate against a DTD locally, but I don't want to change the xml DOCTYPE since that is what the final form needs to be (this app is solely for diagnostic purposes). For more information about the cXML spec, you can go to cxml.org. I appreciate any assistance. Thanks

  • Passing Objects between different files

    - by user309779
    Typically, if I want to pass an object to an instance of something I would do it like so... Listing 1 File 1: public class SomeClass { // Some Properties public SomeClass() { public int ID { get { return mID; } set { mID = value; } } public string Name { set { mName = value; } get { return mName; } } } } public class SomeOtherClass { // Method 1 private void Method1(int one, int two) { SomeClass USER; // Create an instance Squid RsP = new Squid(); RsP.sqdReadUserConf(USER); // Able to pass 'USER' to class method in different file. } } In this example, I was not able to use the above approach. Probably because the above example passes an object between classes. Whereas, below, things are defined in a single class. I had to use some extra steps (trial & error) to get things to work. I am not sure what I did here or what its called. Is it good programming practice? Or is there is an easier way to do this (like above). Listing 2 File 1: private void SomeClass1 { [snip] TCOpt_fM.AutoUpdate = optAutoUpdate.Checked; TCOpt_fM.WhiteList = optWhiteList.Checked; TCOpt_fM.BlackList = optBlackList.Checked; [snip] private TCOpt TCOpt_fM; TCOpt_fM.SaveOptions(TCOpt_fM); } File 2: public class TCOpt: { public TCOpt OPTIONS; [snip] private bool mAutoUpdate = true; private bool mWhiteList = true; private bool mBlackList = true; [snip] public bool AutoUpdate { get { return mAutoUpdate; } set { mAutoUpdate = value; } } public bool WhiteList { get { return mWhiteList; } set { mWhiteList = value; } } public bool BlackList { get { return mBlackList; } set { mBlackList = value; } } [snip] public bool SaveOptions(TCOpt OPTIONS) { [snip] Some things being written out to a file here [snip] Squid soSwGP = new Squid(); soSgP.sqdWriteGlobalConf(OPTIONS); } } File 3: public class SomeClass2 { public bool sqdWriteGlobalConf(TCOpt OPTIONS) { Console.WriteLine(OPTIONS.WhiteSites); // Nothing prints here Console.WriteLine(OPTIONS.BlackSites); // Or here } } Thanks in advance, XO

  • C array assignment and indexing with similar variable.

    - by Todd R.
    Hello! I apologize if this has been posted before. Compiling under two separate compilers, BCC 5.5 and LCC, yields 0 and 1. #include <stdio.h> int main(void) { int i = 0, array[2] = {0, 0}; array[i] = ++i; printf("%d\n", array[1]); } Am I to assume not all compilers evaluate expressions within an array from right to left?

  • Background-image won't change using jquery in IE6

    - by slav
    There is a panel on my page with no default background-image css. On load it is set with jquery to an initial image, waits for 10 seconds then loads a random image out of some predetermined images. There are previous and next buttons which allow you to cycle through the images. In ie6 the initial image loads and then a random image also loads after 10 seconds, however pressing prev/next causes the background to become white and the images aren't loaded. With alerts I was able to find that it's still keeping track of the position and url of the image it's supposed to load, but just won't load it. Here is the code below. <script type="text/javascript"> var facts = new Array(); var position; $(document).ready(function() { <xsl:for-each select="$currentPage/ancestor-or-self::node[@level=1]/../node[@nodeName='Fun Fact Folder']/node"> facts[<xsl:value-of select="position()" />] = '<xsl:value-of select="." />'; </xsl:for-each> if(window.location.pathname == "/homepage.aspx" || window.location.pathname == "/") { $(".fun_facts_bg").css("background-image", "url(images/fun_fact_homepage.JPG)"); setTimeout("randomFact()",10000); } else { randomFact(); } }); function randomFact() { $("a.previous_button").css("display", "block"); $("a.next_button").css("display", "block"); position = Math.ceil(Math.random() * (facts.length - 1)); changeFact(0); } function changeFact(increment) { position = checkPosition(position, increment); $(".fun_facts_bg").css("background-image", "url(" + facts[position] + ")"); } <xsl:text disable-output-escaping="yes">&lt;!--//--&gt;&lt;![CDATA[//&gt;&lt;!-- function checkPosition(currentPos, increment) { currentPos = currentPos + increment; if (currentPos &gt; facts.length - 1) { currentPos = 1; } else if (currentPos &lt; 1) { currentPos = facts.length - 1; } return currentPos; } //--&gt;&lt;!]]&gt;</xsl:text> </script> <a class="previous_button" href="javascript:void(0);" onclick="changeFact(-1);"> <a class="next_button" href="javascript:void(0);" onclick="changeFact(1);">

  • What is the most effective way to test for combined keyboard arrow direction in ActionScript 3.0?

    - by Relee
    I need to monitor the direction a user is indicating using the four directional arrow keys on a keyboard in ActionScript 3.0 and I want to know the most efficient and effective way to do this. I've got several ideas of how to do it, and I'm not sure which would be best. I've found that when tracking Keyboard.KEY_DOWN events, the event repeats as long as the key is down, so the event function is repeated as well. This broke the method I had originally chosen to use, and the methods I've been able to think of require a lot of comparison operators. The best way I've been able to think of would be to use bitwise operators on a uint variable. Here's what I'm thinking var _direction:uint = 0x0; // The Current Direction That's the current direction variable. In the Keyboard.KEY_DOWN event handler I'll have it check what key is down, and use a bitwise AND operation to see if it's already toggled on, and if it's not, I'll add it in using basic addition. So, up would be 0x1 and down would be 0x2 and both up and down would be 0x3, for example. It would look something like this: private function keyDownHandler(e:KeyboardEvent):void { switch(e.keyCode) { case Keyboard.UP: if(!(_direction & 0x1)) _direction += 0x1; break; case Keyboard.DOWN: if(!(_direction & 0x2)) _direction += 0x2; break; // And So On... } } The keyUpHandler wouldn't need the if operation since it only triggers once when the key goes up, instead of repeating. I'll be able to test the current direction by using a switch statement labeled with numbers from 0 to 15 for the sixteen possible combinations. That should work, but it doesn't seem terribly elegant to me, given all of the if statements in the repeating keyDown event handler, and the huge switch. private function checkDirection():void { switch(_direction) { case 0: // Center break; case 1: // Up break; case 2: // Down break; case 3: // Up and Down break; case 4: // Left break; // And So On... } } Is there a better way to do this?

    Hi I have found this code in the internet and it was for arrays ,I want to change it for doubly linked list(instead of index we should use pointer) would you please help me that how can i change merge method(I have changed sort method by myself) also this is not my home work ,I love working with linked list!! public class MergeSort { private DoublyLinkedList LocalDoublyLinkedList; public MergeSort(DoublyLinkedList list) { LocalDoublyLinkedList = list; } public void sort() { if (LocalDoublyLinkedList.size() <= 1) { return; } DoublyLinkedList listOne = new DoublyLinkedList(); DoublyLinkedList listTwo = new DoublyLinkedList(); for (int x = 0; x < (LocalDoublyLinkedList.size() / 2); x++) { listOne.add(x, LocalDoublyLinkedList.getValue(x)); } for (int x = (LocalDoublyLinkedList.size() / 2) + 1; x < LocalDoublyLinkedList.size`(); x++) {` listTwo.add(x, LocalDoublyLinkedList.getValue(x)); } //Split the DoublyLinkedList again MergeSort sort1 = new MergeSort(listOne); MergeSort sort2 = new MergeSort(listTwo); sort1.sort(); sort2.sort(); merge(listOne, listTwo); } private void merge(DoublyLinkedList a, DoublyLinkedList b) { int x = 0; int y = 0; int z = 0; while (x < first.length && y < second.length) { if (first[x] < second[y]) { a[z] = first[x]; x++; } else { a[z] = second[y]; y++; } z++; } //copy remaining elements to the tail of a[]; for (int i = x; i < first.length; i++) { a[z] = first[i]; z++; } for (int i = y; i < second.length; i++) { a[z] = second[i]; z++; } } }

  • Help me understand this "Programming pearls" bitsort program

    - by ardsrk
    Jon Bentley in Column 1 of his book programming pearls introduces a technique for sorting a sequence of non-zero positive integers using bit vectors. I have taken the program bitsort.c from here and pasted it below: /* Copyright (C) 1999 Lucent Technologies */ /* From 'Programming Pearls' by Jon Bentley */ /* bitsort.c -- bitmap sort from Column 1 * Sort distinct integers in the range [0..N-1] */ #include <stdio.h> #define BITSPERWORD 32 #define SHIFT 5 #define MASK 0x1F #define N 10000000 int a[1 + N/BITSPERWORD]; void set(int i) { int sh = i>>SHIFT; a[i>>SHIFT] |= (1<<(i & MASK)); } void clr(int i) { a[i>>SHIFT] &= ~(1<<(i & MASK)); } int test(int i){ return a[i>>SHIFT] & (1<<(i & MASK)); } int main() { int i; for (i = 0; i < N; i++) clr(i); /*Replace above 2 lines with below 3 for word-parallel init int top = 1 + N/BITSPERWORD; for (i = 0; i < top; i++) a[i] = 0; */ while (scanf("%d", &i) != EOF) set(i); for (i = 0; i < N; i++) if (test(i)) printf("%d\n", i); return 0; } I understand what the functions clr, set and test are doing and explain them below: ( please correct me if I am wrong here ). clr clears the ith bit set sets the ith bit test returns the value at the ith bit Now, I don't understand how the functions do what they do. I am unable to figure out all the bit manipulation happening in those three functions. Please help.
