  • UISlider how to set the initial value

    - by slim
    I'm pretty new at this iphone dev stuff and i'm working on some existing code at a company. The uislider i'm trying to set the initial value on is actually in a UITableViewCell and is a custom control. I was thinking in the cell init cell = (QuantitiesCell *)[self loadCellWithNibName:@"QuantitiesCell" forTableView:ltableView withStyle:UITableViewCellStyleDefault]; i could just call something like ((QuantitiesCell *)cell).value = 5; The actual QuantitiesCell class has the member value and the following functions -(void)initCell;{ if (listOfValues == nil) { [self initListOfValues]; } quantitiesSLider.maximumValue = [listOfValues count]-1; quantitiesSLider.minimumValue = 0; quantitiesSLider.value = self.value; } -(void)initListOfValues;{ listOfValues = [[NSMutableArray alloc] initWithCapacity:10]; int j =0; for (float i = minValue; i <= maxValue+increment; i=i+increment) { [listOfValues addObject:[NSNumber numberWithFloat: i]]; if (i == value) { quantitiesSLider.value = j; } j++; } } like i said, i'm pretty new at this so if i need to post more of the code to show whats going to get help, let me know, This slider always is defaulting to 1, the slider ranges usually from 1-10, and i want to set it to a specific value of the item i'm trying to edit.

  • Problem with using malloc in link lists (urgent ! help please)

    - by Abhinav
    I've been working on this program for five months now. Its a real time application of a sensor network. I create several link lists during the life of the program and Im using malloc for creating a new node in the link. What happens is that the program suddenly stops or goes crazy and restarts. Im using AVR and the microcontroller is ATMEGA 1281. After a lot of debugging I figured out that that the malloc is causing the problem. I do not free the memory after exiting the function that creates a new link so Im guessing that this is eventually causing the heap memory to overflow or something like that. Now if I use the free() function to deallocate the memory at the end of the function using malloc, the program just gets stuck when the control reaches free(). Is this because the memory becomes too clustered after calling free() ? I also create reference tables for example if 'head' is a new link list and I create another list called current and make it equal to head. table *head; table *current = head; After the end of the function if I use free free(current); current = NULL: Then the program gets stuck here. I dont know what to do. What am I doing wrong? Is there a way to increase the size of the heap memory Please help...

  • Listing serial (COM) ports on Windows?

    - by Eli Bendersky
    Hello, I'm looking for a robust way to list the available serial (COM) ports on a Windows machine. There's this post about using WMI, but I would like something less .NET specific - I want to get the list of ports in a Python or a C++ program, without .NET. I currently know of two other approaches: Reading the information in the HARDWARE\\DEVICEMAP\\SERIALCOMM registry key. This looks like a great option, but is it robust? I can't find a guarantee online or in MSDN that this registry cell indeed always holds the full list of available ports. Tryint to call CreateFile on COMN with N a number from 1 to something. This isn't good enough, because some COM ports aren't named COMN. For example, some virtual COM ports created are named CSNA0, CSNB0, and so on, so I wouldn't rely on this method. Any other methods/ideas/experience to share? Edit: by the way, here's a simple Python implementation of reading the port names from registry: import _winreg as winreg import itertools def enumerate_serial_ports(): """ Uses the Win32 registry to return a iterator of serial (COM) ports existing on this computer. """ path = 'HARDWARE\\DEVICEMAP\\SERIALCOMM' try: key = winreg.OpenKey(winreg.HKEY_LOCAL_MACHINE, path) except WindowsError: raise IterationError for i in itertools.count(): try: val = winreg.EnumValue(key, i) yield (str(val[1]), str(val[0])) except EnvironmentError: break

  • Use AJAX to reload captcha

    - by arik-so
    Hello! This question may have been asked already - but unfortunately, I could not find any satisfactory answers. I will just ask it for my concrete case and ask the admins not to delete the question for at least a few days so I can try it out... I have a page. It uses a captcha. Like so: <?php session_start(); // the captcha saves the md5 into the session ?> <img src="captcha.php" onclick="this.src = this.src" /> That was my first code. It did not work, because the browser condsidered it useless to reload an image if the source is the same. My current solution is to pass a get parameter: onclick="this.src = 'captcha.php?randomNumber='+ranNum" The JavaScript variable var ranNum is generated randomly every time the onclick event fires. It works fine, still, I don't like the possibility, if the - though improbable - case of two numbers being the same twice in a row. Although the random number varies between -50,000 and 50,000 - I still do not like it. And I don't think the method is right. I would like to know the 'righter' method, by means of AJAX. I know it's possible. I hope you know how it's possible ^^ In that case, please show me. Thanks in advance! By the way - if I spell cap(t)cha differently, never mind, the reference to the PHP file is right in my code: I use randomImage.php

  • JDO difficulties in retrieving persistent vector

    - by Michael Omer
    I know there are already some posts regarding this subject, but although I tried using them as a reference, I am still stuck. I have a persistent class as follows: @PersistenceCapable(identityType = IdentityType.APPLICATION) public class GameObject implements IMySerializable{ @PrimaryKey @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY) protected Key m_databaseKey; @NotPersistent private final static int END_GAME_VAR = -1000; @Persistent(defaultFetchGroup = "true") protected GameObjectSet m_set; @Persistent protected int m_databaseType = IDatabaseAccess.TYPE_NONE; where GameObjectSet is: @PersistenceCapable(identityType = IdentityType.APPLICATION) @FetchGroup(name = "mySet", members = {@Persistent(name = "m_set")}) public class GameObjectSet { @PrimaryKey @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY) private Key id; @Persistent private Vector<GameObjectSetPair> m_set; and GameObjectSetPair is: @PersistenceCapable(identityType = IdentityType.APPLICATION) public class GameObjectSetPair { @PrimaryKey @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY) private Key id; @Persistent private String key; @Persistent(defaultFetchGroup = "true") private GameObjectVar value; When I try to fetch the entire structure by fetching the GameObject, the set doesn't have any elements (they are all null) I tried adding the fetching group to the PM, but to no avail. This is my fetching code Vector<GameObject> ret = new Vector<GameObject>(); PersistenceManager pm = PMF.get().getPersistenceManager(); pm.getFetchPlan().setMaxFetchDepth(-1); pm.getFetchPlan().addGroup("mySet"); Query myQuery = pm.newQuery(GameObject.class); myQuery.setFilter("m_databaseType == objectType"); myQuery.declareParameters("int objectType"); try { List<GameObject> res = (List<GameObject>)myQuery.execute(objectType); ret = new Vector<GameObject>(res); for (int i = 0; i < ret.size(); i++) { ret.elementAt(i).getSet(); ret.elementAt(i).getSet().touchSet(); } } catch (Exception e) { } finally { pm.close(); } Does anyone have any idea? Thanks Mike

  • JS: capture a static snapshot of an object at a point in time with a method

    - by Barney
    I have a JS object I use to store DOM info for easy reference in an elaborate GUI. It starts like this: var dom = { m:{ old:{}, page:{x:0,y:0}, view:{x:0,y:0}, update:function(){ this.old = this; this.page.x = $(window).width(); this.page.y = $(window).height(); this.view.x = $(document).width(); this.view.y = window.innerHeight || $(window).height(); } I call the function on window resize: $(window).resize(function(){dom.m.update()}); The problem is with dom.m.old. I would have thought that by calling it in the dom.m.update() method before the new values for the other properties are assigned, at any point in time dom.m.old would contain a snapshot of the dom.m object as of the last update – but instead, it's always identical to dom.m. I've just got a pointless recursion method. Why isn't this working? How can I get a static snapshot of the object that won't update without being specifically told to? Comments explaining how I shouldn't even want to be doing anything remotely like this in the first place are very welcome :)

  • Retrieve property from classpath inside POM

    - by Jeroen
    For my current project I want to integrate a maven plug-in for database migrations. For this plug-in to work, however, I have to obtain the database settings inside my POM. My database settings are currently placed inside a hibernate.properties file, positioned in a directory that is marked as maven resource. For a variety of reasons I do not want to duplicate my database configurations in both the pom and hibernate.properties. I'm aware that maven offers a "filtering" ability which makes it possible to specify the database settings as property inside my POM, and reference them inside my hibernate.properties as ${property_name}. But as I'm using multiple maven profiles, with different property resources, this is not a suitable solution. Instead I'd like my database configurations to be loaded from a property file inside my classpath (e.g. classpath:hibernate.properties), and use these properties in my migration plug-in configuration. I have already tried the org.codehaus.mojo » properties-maven-plugin, but this plug-in only accepts absolute locations. Is there a plug-in which can scan all my maven resources for a certain property?

  • How do I add and remove an event listener using a function with parameters?

    - by Bungle
    Sorry if this is a common question, but I couldn't find any answers that seemed pertinent through searching. If I attach an event listener like this: window.addEventListener('scroll', function() { check_pos(box); }, false); it doesn't seem to work to try to remove it later, like this: window.removeEventListener('scroll', function() { check_pos(box); }, false); I assume this is because the addEventListener and removeEventListener methods want a reference to the same function, while I've provided them with anonymous functions, which, while identical in code, are not literally the same. How can I change my code to get the call to removeEventListener to work? The "box" argument refers to the name of an <iframe> that I'm tracking on the screen; that is, I want to be able to subscribe to the scroll event once for each <iframe> that I have (the quantity varies), and once the check_pos() function measures a certain position, it will call another function and also remove the event listener to free up system resources. My hunch is that the solution will involve a closure and/or naming the anonymous function, but I'm not sure exactly what that looks like, and would appreciate a concrete example. Hope that makes sense. Thanks for any help!

  • How can I initialize a QTMovie object with certain attributes using writable data?

    - by c-had
    I'm trying to create an empty QTMovie object that I can add segments to, and then play. This is easy to do with something like: movie = [[QTMovie alloc] initToWritableData:[NSMutableData dataWithCapacity:1048576] error:&error]; I can then use -insertSegmentOfMovie to insert segments from other movies into this one so I can play it back. The problem is that I also need to set a certain attribute when creating the QTMovie object. In particular, I need to set the QTMovieRateChangesPreservePitchAttribute attribute, so that I can alter playback speed during playback without changing pitch. This attribute cannot be written after the movie is initialized. So, I can create the QTMovie object like this: movie = [[QTMovie alloc] initWithAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[NSNumber numberWithBool:YES], QTMovieRateChangesPreservePitchAttribute, nil] error:&error]; Unfortunately, this is not editable. I've tried setting the QTMovieEditableAttribute as well on creation, but it does not help. I still get an exception when I try to insert anything into this movie. I presume this is because there is no writable file or data reference associated with the QTMovie. Any ideas on how to solve this?

  • Path to XML DTD for DBUnit in multi-module Java/Maven project?

    - by HDave
    I have a multi-module maven project. Within the persist module I have a number of XML files data files that reference a DTD: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE myapp-data SYSTEM "myapp-data.dtd" > <dataset> .....omitted for brevity.... </dataset> The DTD is stored in the same directory with the XML files and even Eclipse reports these XML files as valid. However, when I run the application, the DBUnit FlatXMLDataSet throws a FileNotFound exception because it cannot located the DTD. It is apparently looking for the DTD in the root project directory (e.g. myproject/). I would have expected it to look for the DTD in the same directory as the XML file itself (e.g. myproject/persist/target/test-data). Looking at the DBUnit source code, it has this to say about it "Relative DOCTYPE uri are resolved from the current working dicrectory." What's a good way to fix this?

  • function php with parameter 0

    - by Arnaud Ncy
    I have a function like this public function get_page($position) { switch ($position) { case "current": echo "current"; return $this->current_page; break; case "first": echo "first"; return $this->current_page >= 3 ? 1 : false; break; case "last": echo "last"; return $this->current_page <= $this->total_pages() - 2 ? ceil($this->count / $this->nb_items_to_show) : false; break; case "previous": echo "previous"; return $this->current_page - 1 >= 1 ? $this->current_page - 1 : false; break; case "next": echo "next"; return $this->current_page + 1 <= $this->total_pages() ? $this->current_page + 1 : false; break; case is_int($position): echo "int"; if ($position >= 1 && $position <= $this->total_pages()) { return $position; } else { return false; } break; default: echo "default"; return false; break; } } When I call the function, it works for every parameters except 0 and goes in "current" case in the switch. $paginator->get_page(0); If I call the function with quotes "0", it works. But the function could be called like this $paginator->get_page($paginator->get_page("current") - 2); How can I call the function with parameter 0 ?

  • Delphi Unicode String Type Stored Directly at its Address (or "Unicode ShortString")

    - by Andreas Rejbrand
    I want a string type that is Unicode and that stores the string directly at the adress of the variable, as is the case of the (Ansi-only) ShortString type. I mean, if I declare a S: ShortString and let S := 'My String', then, at @S, I will find the length of the string (as one byte, so the string cannot contain more than 255 characters) followed by the ANSI-encoded string itself. What I would like is a Unicode variant of this. That is, I want a string type such that, at @S, I will find a unsigned 32-bit integer (or a single byte would be enough, actually) containing the length of the string in bytes (or in characters, which is half the number of bytes) followed by the Unicode representation of the string. I have tried WideString, UnicodeString, and RawByteString, but they all appear only to store an adress at @S, and the actual string somewhere else (I guess this has do do with reference counting and such). Update: The most important reason for this is probably that it would be very problematic if sizeof(string) were variable. I suspect that there is no built-in type to use, and that I have to come up with my own way of storing text the way I want (which actually is fun). Am I right? Update I will, among other things, need to use these strings in packed records. I also need manually to read/write these strings to files/the heap. I could live with fixed-size strings, such as <= 128 characters, and I could redesign the problem so it will work with null-terminated strings. But PChar will not work, for sizeof(PChar) = 1 - it's merely an address. The approach I eventually settled for was to use a static array of bytes. I will post my implementation as a solution later today.

  • ajax to php to curl and back..

    - by pfunc
    I am trying to make an ajax call to a php script. The php script calls an rss feed using curl, gets the data, and returns the data to the funciton. I keep getting an error "Warning: Wrong parameter count for curl_error() in" .... Here is my php code:1 $ch = curl_init() or die(curl_error()); curl_setopt($ch, CURLOPT_URL, $feed); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); $data1 = curl_exec($ch) or die(curl_error()); echo $data1; and the ajax call: $.ajax({ url: "getSingleFeed.php", type: "POST", data: "feedURL=" + window.feedURL, success: function(feed){ alert(feed); }}); I tested all the variables, they are being passed correctly, I can echo them out. But this line: $data1 = curl_exec($ch) or die(curl_error()); is what is giving me the error. I am doing the same thing with curl on other pages, just without ajax, and it is working fine. Is there anything special I need to do with ajax to do this?

  • Create xml file to be used in wordpress post import

    - by adedoy
    Alright here is the thing, I have this site that was once wordpress but have been converted into 70+ static pages, the admin is deleted and the whole site is static(which means every page is in index.html), I want to create a script that makes an xml so that I will just have to import it in the new wordpress install. So far, I am able to create an XML but it only imports one post. The data source is the URL of a page and I use jquery $get to filter only to gather the post of a given archive. //html <input type="text" class="full_path"> <input type="button" value="Get Data" class="getdata"> //script $('.getdata').click(function(){ $.get($('.full_path').val(), function(data) { post = $(data).find('div [style*="width:530px;"]'); $('.result').html(post.html()); }); });//get Data Through AJAX I send the cleaned data into a php below that creates the XML: $file = 'newpost.xml'; $post_data = $_REQUEST['post_data']; // Open the file to get existing content $current = file_get_contents($file); // Append a new post to the file $catStr = ''; if(isset($post_data['categories']) && count($post_data['categories']) > 0){ foreach($post_data['categories'] as $category) { $catStr .= '<category domain="category" nicename="'.$category.'"><![CDATA['.$category.']]></category>'; } } $tagStr = ''; if(isset($post_data['tags']) && count($post_data['tags']) > 0){ foreach($post_data['tags'] as $tag) { $tagStr = '<category domain="post_tag" nicename="'.$tag.'"><![CDATA['.$tag.']]></category>'; } } $post_name = str_replace(' ','-',$post_data["title"]); $post_name = str_replace(array('"','/',':','.',',','[',']','“','”'),'',strtolower($post_name)); $post_date = '2011-4-0'.rand(1, 29).''.rand(1, 12).':'.rand(1, 59).':'.rand(1, 59); $pubTime = rand(1, 12).':'.rand(1, 59).':'.rand(1, 59).' +0000'; $post = ' <item> <title>'.$post_data["title"].'</title> <link>'.$post_data["link"].'</link> <pubDate>'.$post_data["date"].'

  • iPhone Core Data does not refresh table

    - by Brian515
    Hi all, I'm trying to write an application with Core Data, and I have been able to successfully read and write to the core data database. However, if I write to the database in one view controller, my other view controllers will not see the change until the app is closed then reopened again. This is really frustrating. I'm not entirely sure how to get the refresh - (void)refreshObject:(NSManagedObject *)object mergeChanges:(BOOL)flag method to work. How do I get a reference to my managed object? Anyways, here's the code I'm using to read the data back. This is in the viewDidLoad method. NSFetchRequest *request = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"Website" inManagedObjectContext:managedObjectContext]; [request setEntity:entity]; NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"siteName" ascending:NO]; NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:sortDescriptor, nil]; [request setSortDescriptors:sortDescriptors]; [sortDescriptor release]; [sortDescriptors release]; NSError *error = nil; NSMutableArray *mutableFetchResults = [[managedObjectContext executeFetchRequest:request error:&error] mutableCopy]; if(mutableFetchResults == nil) { //Handle the error } [self setNewsTitlesArray:mutableFetchResults]; [mutableFetchResults release]; [request release]; [newsSourcesTableView reloadData]; Thanks for help in advance!

  • Facebook SDK Comment Deleting

    - by mwoodworth
    Working with the Facebook php SDK's, I am having a lot of trouble figuring out how to delete comments, given its id and xid. At first I was using the REST API, where you can call 'comments_remove($xid, $id);' to delete a comment. The problem with this method came when the xid parameter only accepts alphanumeric characters and underscores. Based on the documentation (http://developers.facebook.com/docs/reference/fbml/comments ) a valid XID can be the result of any url_encode. Now I am testing my luck with the new GRAPH api. Looking at http://developers.facebook.com/docs/api under 'Deleting Objects', It seems that comment deleting is definitely supported. However, I have tried sending a DELETE request, and I have also tried sending POST and GET to the object url with the argument 'method=delete'. No matter how I try it, I always get the same error: {"error":{"type":"GraphMethodException","message":"Unsupported delete request."}} I am sending the access token as a parameter as well. The access token that I am sending is the access token saved in the facebook cookie from the single sign on javascript cookie. These are all comments made on my application. Does this happen to anyone else, or am I simply not doing this right? Any help or guidance is GREATLY appreciated.

  • Why do my raytraced spheres have dark lines when lit with multiple light sources?

    - by Curyous
    I have a simple raytracer that only works back up to the first intersection. The scene looks OK with two different light sources, but when both lights are in the scene, there are dark shadows where the lit area from one ends, even if in the middle of a lit area from the other light source (particularly noticeable on the green ball). The transition from the 'area lit by both light sources' to the 'area lit by just one light source' seems to be slightly darker than the 'area lit by just one light source'. The code where I'm adding the lighting effects is: // trace lights for ( int l=0; l<primitives.count; l++) { Primitive* p = [primitives objectAtIndex:l]; if (p.light) { Sphere * lightSource = (Sphere *)p; // calculate diffuse shading Vector3 *light = [[Vector3 alloc] init]; light.x = lightSource.centre.x - intersectionPoint.x; light.y = lightSource.centre.y - intersectionPoint.y; light.z = lightSource.centre.z - intersectionPoint.z; [light normalize]; Vector3 * normal = [[primitiveThatWasHit getNormalAt:intersectionPoint] retain]; if (primitiveThatWasHit.material.diffuse > 0) { float illumination = DOT(normal, light); if (illumination > 0) { float diff = illumination * primitiveThatWasHit.material.diffuse; // add diffuse component to ray color colour.red += diff * primitiveThatWasHit.material.colour.red * lightSource.material.colour.red; colour.blue += diff * primitiveThatWasHit.material.colour.blue * lightSource.material.colour.blue; colour.green += diff * primitiveThatWasHit.material.colour.green * lightSource.material.colour.green; } } [normal release]; [light release]; } } How can I make it look right?

  • C++ Returning Multiple Items

    - by Travis Parks
    I am designing a class in C++ that extracts URLs from an HTML page. I am using Boost's Regex library to do the heavy lifting for me. I started designing a class and realized that I didn't want to tie down how the URLs are stored. One option would be to accept a std::vector<Url> by reference and just call push_back on it. I'd like to avoid forcing consumers of my class to use std::vector. So, I created a member template that took a destination iterator. It looks like this: template <typename TForwardIterator, typename TOutputIterator> TOutputIterator UrlExtractor::get_urls( TForwardIterator begin, TForwardIterator end, TOutputIterator dest); I feel like I am overcomplicating things. I like to write fairly generic code in C++, and I struggle to lock down my interfaces. But then I get into these predicaments where I am trying to templatize everything. At this point, someone reading the code doesn't realize that TForwardIterator is iterating over a std::string. In my particular situation, I am wondering if being this generic is a good thing. At what point do you start making code more explicit? Is there a standard approach to getting values out of a function generically?

  • Linked List pop() function

    - by JKid314159
    Consider the following list: [LinkNode * head -- LinkNode * node1 -- LinkNode * node2] I'm creating a stack of FIFO. I Call pop() which I want to pop node1. LinkNode::LinkNode(int numIn) { this->numIn = numIn; next = null; } . . . int LinkNode::pop() { Link * temp = head->next; head = temp->next; int popped = head->nodeNum; delete temp; Return numOut; Question: 1) head should be a pointer or a LinkNode *? 2) Link * temp is created on the call stack and when pop finishes doesn't temp delete automatically? 3) My major confusion is on what is the value of temp-next? Does this point to node1.next which equals node2? Appreciate your help? My reference is C++ for Java Programmers by Weiss.

  • How can I loop thru all controls (including ToolStripItems) C#

    - by Murray
    I need to save and restore settings for specific controls on a form. I loop thru all controls and return the one whose name matches the one I want, like so: private static Control GetControlByName(string name, Control.ControlCollection Controls) { Control thisControl = null; foreach (Control c in Controls) { if (c.Name == name) { thisControl = c; break; } if (c.Controls.Count > 0) { thisControl = GetControlByName(name, c.Controls); if (thisControl != null) { break; } } } return thisControl; } From this I can determine the type of control and therefore the property that should be / has been stored. This works well unless the control is one of the ToolStrip family which has been added to a toolstrip. e.g. this.toolStrip.Items.AddRange(new System.Windows.Forms.ToolStripItem[] { this.lblUsername, // ToolStripLabel this.toolStripSeparator1, this.cbxCompany}); // ToolStripComboBox In this case I can see the control I'm interested in (cbxCompany) when debugging, but the name property has no value so the code does not match to it. Any suggestions on how I can get to these controls too? Cheers, Murray

  • How do I add ROW_NUMBER to a LINQ query or Entity?

    - by Whozumommy
    I'm stumped by this easy data problem. I'm using the Entity framework and have a database of products. My results page returns a paginated list of these products. Right now my results are ordered by the number of sales of each product, so my code looks like this: return Products.OrderByDescending(u => u.Sales.Count()); This returns an IQueryable dataset of my entities, sorted by the number of sales. I want my results page to show the rank of each product (in the dataset). My results should look like this: Page #1 1. Bananas 2. Apples 3. Coffee Page #2 4. Cookies 5. Ice Cream 6. Lettuce I'm expecting that I just want to add a column in my results using the SQL ROW_NUMBER variable...but I don't know how to add this column to my results datatable. My resulting page does contain a foreach loop, but since I'm using a paginated set I'm guessing using that number to fake a ranking number would NOT be the best approach. So my question is, how do I add a ROW_NUMBER column to my query results in this case?
