• How to ship numpy with web2py application under myapp/modules?

  - by Newbie07

  I am having the following error while importing numpy from application/myapp/modules: Traceback (most recent call last): File "/home/mdipierro/make_web2py/web2py/gluon/restricted.py", line 212, in restricted File "D:/web2py_win/web2py/applications/myapp/controllers/default.py", line 13, in File "/home/mdipierro/make_web2py/web2py/gluon/custom_import.py", line 100, in custom_importer File "applications\myapp\modules\numpy\ __init__.py", line 137, in File "/home/mdipierro/make_web2py/web2py/gluon/custom_import.py", line 81, in custom_importer ImportError: Cannot import module 'add_newdocs' I tried adding 'application.myapp.modules.' in the 'import add_newdocs' statement of numpy\ __init.py__ and the error propagates to other subsequent imports(i.e. add_docs imports some other stuff and I get the ImportError again for these imports). So I narrowed down the problem to the "working directory" of the import statement. However, I do not wish to add 'application.myapp.modules.' in every import statement inside the package since it would be impractical and hard to edit if someone decides to rename the app later on. How do I make the import work smoothly? NOTE: It is necessary for me to put the numpy package in the app to ensure ease of deployment.

• Objective-C basics: subclassing and member variable accessability

  - by Krumelur

  Hi, Code below is pseudo code. Imagine a class "Fruit" which has a factory method to create a fruit. interface Fruit { } +(Fruit*) createFruit: { return [[Fruit alloc] init autorelease]; } Now I want to subclass the Fruit to get an Apple: interface Apple : Fruit { int iSeeds; } +(Apple*) createAppleWithColor: (int) iSeeds { Apple* oApple = [Apple createFruit:]; oApple.iSeeds = iSeeds; return oApple; } Questions: How can I make "iSeeds" private so it cannot be changed from outside? If I add a "private" keyword it does not build anymore. Still I want to set iSeeds from inside my Apple's factory method. I want users allow to READ the content of iSeeds. So I suppose I should have a getter but I can't get it to work. I always get some error about "LValue assignment". The Fruit's createFruit is making use of autorelease. Does the Apple have to reatin/release anything? René

• Getting exception when trying to monkey patch pymongo.connection._Pool

  - by Creotiv

  I use pymongo 1.9 on Ubuntu 10.10 with python 2.6.6 When i trying to monkey patch pymongo.connection._Pool i'm getting error on connection: AutoReconnect: could not find master/primary But when i change _Pool class in pymongo.connection module, it work pretty fine. Even if i copy _Pool implementation from pymongo.connection module and will try to monkey patch by the same code, it still giving same exception. I need to remove threading.local from _Pool class, because i use gevent and i need to implement Pool for all mongo connections(for all threads). I use this code: import pymongo class GPool: """A simple connection pool. Uses thread-local socket per thread. By calling return_socket() a thread can return a socket to the pool. Right now the pool size is capped at 10 sockets - we can expose this as a parameter later, if needed.

• Refresh decorator

  - by Morgoth

  I'm trying to write a decorator that 'refreshes' after being called, but where the refreshing only occurs once after the last function exits. Here is an example: @auto_refresh def a(): print "In a" @auto_refresh def b(): print "In b" a() If a() is called, I want the refresh function to be run after exiting a(). If b() is called, I want the refresh function to be run after exiting b(), but not after a() when called by b(). Here is an example of a class that does this: class auto_refresh(object): def __init__(self, f): print "Initializing decorator" self.f = f def __call__(self, *args, **kwargs): print "Before function" if 'refresh' in kwargs: refresh = kwargs.pop('refresh') else: refresh = False self.f(*args, **kwargs) print "After function" if refresh: print "Refreshing" With this decorator, if I run b() print '---' b(refresh=True) print '---' b(refresh=False) I get the following output: Initializing decorator Initializing decorator Before function In b Before function In a After function After function --- Before function In b Before function In a After function After function Refreshing --- Before function In b Before function In a After function After function So when written this way, not specifying the refresh argument means that refresh is defaulted to False. Can anyone think of a way to change this so that refresh is True when not specified? Changing the refresh = False to refresh = True in the decorator does not work: Initializing decorator Initializing decorator Before function In b Before function In a After function Refreshing After function Refreshing --- Before function In b Before function In a After function Refreshing After function Refreshing --- Before function In b Before function In a After function Refreshing After function because refresh then gets called multiple times in the first and second case, and once in the last case (when it should be once in the first and second case, and not in the last case).

• [Cocoa] Binding CoreData Managed Object to NSTextFieldCell subclass

  - by ndg

  I have an NSTableView which has its first column set to contain a custom NSTextFieldCell. My custom NSTextFieldCell needs to allow the user to edit a "desc" property within my Managed Object but to also display an "info" string that it contains (which is not editable). To achieve this, I followed this tutorial. In a nutshell, the tutorial suggests editing your Managed Objects generated subclass to create and pass a dictionary of its contents to your NSTableColumn via bindings. This works well for read-only NSCell implementations, but I'm looking to subclass NSTextFieldCell to allow the user to edit the "desc" property of my Managed Object. To do this, I followed one of the articles comments, which suggests subclassing NSFormatter to explicitly state which Managed Object property you would like the NSTextFieldCell to edit. Here's the suggested implementation: @implementation TRTableDescFormatter - (BOOL)getObjectValue:(id *)anObject forString:(NSString *)string errorDescription:(NSString **)error { if (anObject != nil){ *anObject = [NSDictionary dictionaryWithObject:string forKey:@"desc"]; return YES; } return NO; } - (NSString *)stringForObjectValue:(id)anObject { if (![anObject isKindOfClass:[NSDictionary class]]) return nil; return [anObject valueForKey:@"desc"]; } - (NSAttributedString*)attributedStringForObjectValue:(id)anObject withDefaultAttributes:(NSDictionary *)attrs { if (![anObject isKindOfClass:[NSDictionary class]]) return nil; NSAttributedString *anAttributedString = [[NSAttributedString alloc] initWithString: [anObject valueForKey:@"desc"]]; return anAttributedString; } @end I assign the NSFormatter subclass to my cell in my NSTextFieldCell subclass, like so: - (void)awakeFromNib { TRTableDescFormatter *formatter = [[[TRTableDescFormatter alloc] init] autorelease]; [self setFormatter:formatter]; } This seems to work, but is extremely patch. On occasion, clicking to edit a row will cause its value to nullify. On other occasions, the value you enter on one row will populate other rows within the table. I've been doing a lot of reading on this subject and would really like to get to the bottom of this. What's more frustrating is that my NSTextFieldCell is rendering exactly how I would like it to. This editing issue is my last obstacle! If anyone can help, that would be greatly appreciated.

• In facebook connect, how can I check if a user is a fan of my facebook page? Is it possible to track

  - by Tony

  I am trying to determine if a user is a facebook fan. I load the facebook JS library and initialize: <script type="text/javascript" src="http://static.ak.connect.facebook.com/js/api_lib/v0.4/FeatureLoader.js.php/en_US"></script> FB_RequireFeatures(["XFBML","Connect","Api"], function() { FB.init("my_api_key","xd_receiver.htm") }); FB.ensureInit(function () { FB.ApiClient.pages_isFan(my_profile_id,"some_UID",callback); }); However when I call the API client with FB.ApiClient.pages_isFan, I get a JS error - FB.ApiClient is undefined I am also using the FBML fan tag to display the "become a fan" button: <fb:fan profile_id="my_profile_id" stream="0" connections="10" logobar="1" width="300"></fb:fan> And would like to be notified when either the "become a fan" button is clicked or a user has successfully become a fan. The business logic is pretty simple - If they become a fan, track it in my database. Then if they try to become a fan again, check with the library if they are a fan and say "You are already a fan" if they are a fan, show the widget if not.

• ASIHTTPRequest wrapper usage for Macs

  - by Rob

  I am trying to apply the ASIHTTPRequest wrapper to a very basic Objective C program. I have already copied over the necessary files into my program and after giving myself an extreme headache trying to figure out how it works through their website I thought I would post a question on here. The files copied over were: ASIHTTPRequestConfig.h ASIHTTPRequestDelegate.h ASIProgressDelegate.h ASIInputStream.h ASIInputStream.m ASIHTTPRequest.h ASIHTTPRequest.m ASIFormDataRequest.h ASIFormDataRequest.m My program is very basic: #import <Foundation/Foundation.h> int main (int argc, const char * argv[]) { NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init]; // Defining the various variables. char firstName[20]; char lastName[20]; char rank[5]; int leaveAccrued; int leaveRequested; // User Input. NSLog (@"Please input First Name:"); scanf("%s", &firstName); NSLog (@"Please input Last Name:"); scanf("%s", &lastName); NSLog (@"Please input Rank:"); scanf("%s", &rank); NSLog (@"Please input the number leave days you have accrued:"); scanf("%i", &leaveAccrued); NSLog (@"Please input the number of leave days you are requesting:"); scanf("%i", &leaveRequested); // Print results. NSLog (@"Name: %s %s", firstName, lastName); NSLog (@"Rank: %s", rank); NSLog (@"Leave Accrued: %i", leaveAccrued); NSLog (@"Leave Requested: %i", leaveRequested); [pool drain]; return 0; } How do I utilize the wrapper to export these 5 basic variables to a web server via an http request?

• Memory leak when returning object

  - by Yakattak

  I have this memory leak that has been very stubborn for the past week or so. I have a class method I use in a class called "ArchiveManager" that will unarchive a specific .dat file for me, and return an array with it's contents. Here is the method: +(NSMutableArray *)unarchiveCustomObject { NSMutableArray *array = [NSMutableArray arrayWithArray:[NSKeyedUnarchiver unarchiveObjectWithFile:/* Archive Path */]]; return array; } I understand I don't have ownership of it at this point, and I return it. CustomObject *myObject = [[ArchiveManager unarchiveCustomObject] objectAtIndex:0]; Then, later when I unarchive it in a view controller to be used (I don't even create an array of it, nor do I make a pointer to it, I just reference it to get something out of the array returned by unarchiveCustomIbject (objectAtIndex). This is where Instruments is calling a memory leak, yet I don't see how this can leak! Any ideas? Thanks in advance. Edit: CustomObject initWithCoder added: -(id)initWithCoder:(NSCoder *)aDecoder { if (self = [super init]) { self.string1 = [aDecoder decodeObjectForKey:kString1]; self.string2 = [aDecoder decodeObjectForKey:kString2]; self.string3 = [aDecoder decodeObjectForKey:kString3]; UIImage *picture = [[UIImage alloc] initWithData:[aDecoder decodeObjectForKey:kPicture]]; self.picture = picture; self.array = [aDecoder decodeObjectForKey:kArray]; [picture release]; } return self; }

• Setting spring bean property value using ref-bean

  - by Apache Fan

  Hi, I am trying to set a property value using spring. <bean id="velocityPropsBean" class="com.test.CustomProperties" abstract="false" singleton="true" lazy-init="false" autowire="default" dependency-check="default"> <property name="properties"> <props> <prop key="resource.loader">file</prop> <prop key="file.resource.loader.cache">true</prop> <prop key="file.resource.loader.class">org.apache.velocity.runtime.resource.loader.FileResourceLoader</prop> <prop key="file.resource.loader.path">NEED TO INSERT VALUE AT STARTUP</prop> </props> </property> </bean> <bean id="velocityResourcePath" class="java.lang.String" factory-bean="velocityHelper" factory-method="getLoaderPath"/> Now what i need to do is insert the result from getLoaderPath into file.resource.loader.path. The value of getLoaderPath changes so it has to be loaded at server startup. Any thoughts how i can inset the velocityResourcePath value to the property?

• Problem with TTWebController… alternative view controller template for UIWebView?

  - by prendio2

  I have a UIWebView with content populated from a Last.fm API call. This content contains links, many of which are handled by parsing info from the URL in: - (BOOL)webView:(UIWebView *)aWbView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType; …and passing that info on to appropraite view controllers. When I cannot handle a URL I would like to push a new view controller on the stack and load the webpage into a UIWebView there. The TTWebController in Three20 looks very promising since it has also implemented a navigation toolbar, loading indicators etc. Somewhat naively perhaps I thought I would be able to use this controller to display web content in my app, without implementing Three20 throughout the app. I followed the instructions on github to add Three20 to my project and added the following code to deal with URLs in shouldStartLoadWithRequest: TTWebController* browser = [[TTWebController alloc]init]; [browser openURL:@"http://three20.info"]; //initially test with this URL [self.navigationController pushViewController:navigator animated:YES]; This crashes my app however with the following notice: *** -[TTNavigator setParentViewController:]: unrecognized selector sent to instance 0x3d5db70 What else do I need to do to implement the TTWebController in my app? Or do you know of an alternative view controller template that I can use instead of the Three20 implementation?

• iPhone: Accessing Composite Name in AddressBook Causes EXC_BAD_ACCESS

  - by Fyrian

  Hi everyone. I'm new to iPhone development and have a question I hope someone can help me with. I have a programmer working on an iPhone app for me and when I run the app in the simulator, it works great. But when I try to run it on my actual iPhone, I get a EXC_BAD_ACCESS error and the app locks up. Looking at the debugger, it's referencing the following code in my MainController as the problem: -(void)loadAddressBook{ NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; addressBookLoaded=1; [AddressbookRecord readAllContactTable:[self getDBPath]]; ABAddressBookRef addressBook = ABAddressBookCreate(); for(NSUInteger i=1;i<=ABAddressBookGetPersonCount(addressBook);i++) { ABRecordRef myPerson =ABAddressBookGetPersonWithRecordID (addressBook,(ABRecordID)(i)); NSString *name = (NSString*)ABRecordCopyCompositeName(myPerson); //save in database AddressbookRecord *addObj = [[AddressbookRecord alloc] initWithPrimaryKey:0]; addObj.ClientName=name; [addObj addNewContactEntry]; } addressBookLoaded=2; [pool release]; } More specifically, it points to this specific line as the problem: NSString *name =(NSString*)ABRecordCopyCompositeName(myPerson); My programmer can't seem to figure out what the problem is since he can't replicate it on his end. Does anyone have any ideas what would cause this problem??? Thanks!

• Dealing with Try/Catch Exceptions in Java bytecode? ("stack height inconsistent")

  - by Cogwirrel

  I am trying to do some error handling in java bytecode. I first tried to implement some catch-like subroutines, where I would check for the error condition, and jump to the appropriate subroutine, a little like: iconst_1 iconst_0 dup ifeq calldiverr goto enddivtest calldiverr: jsr divError enddivtest: idiv ...More instructions... divError: getstatic java/lang/System/out Ljava/io/PrintStream; ldc "Oh dear you divided by 0!" invokevirtual java/io/PrintStream/print(Ljava/lang/String;)V The problem with the above is that when I have multiple instructions that jump to this subroutine, I get an error message when running the bytecode, saying that the stack height is inconsistent. Perhaps using exceptions is the best way to get around this? From some googling I have found that you can create instances of Exception classes and initialise them with something like: new java/lang/Exception dup ldc "exception message!" invokespecial java/lang/Exception/<init>(Ljava/lang/String;)V I have also found that you can throw them with athrow and this seems ok. What is confusing me however is exactly how exceptions are caught. There seems to be a magical "Exception table" which glues the throwing and catching of exceptions together, but I do not know how to define one of these when writing bytecode from scratch (and assembling using Jasmin). Can somebody tell me the secret of creating an exception table? And possibly give me an example of exception handling that will assemble with jasmin?

• TinyMce imagemanager won't generate image path when used with an iframe

  - by Tom

  I have successfully setup tinymce to work on a page within an iframe. Everything works perfectly. However, when you use imagemanager to pick an image to be inserted or replaced in the editor it will not copy the path(and filename) of the image to the "Image URL" input in the "Insert/edit image" box. The box will either remain empty or keep the address of the previous image. The behaviour is the same with the filemanager plugin. tinyMCE.init( { mode : "none", editor_selector : "mceEditor", theme : "advanced", plugins : "filemanager,imagemanager,autoresize,safari,pagebreak,style,layer,table,save,advhr,advimage,advlink,emotions,iespell,insertdatetime,preview,media,searchreplace,print,contextmenu,paste,directionality,fullscreen,noneditable,visualchars,nonbreaking,xhtmlxtras,template,inlinepopups,spellchecker", theme_advanced_buttons1 : "insertfile,insertimage,advimage,imagemanager,bold,italic,underline,|,justifyleft,justifycenter,justifyright,justifyfull,nonbreaking,cut,copy,paste,pastetext,pasteword,|,search,replace,|,bullist,numlist", theme_advanced_buttons2 : "blockquote,|,link,unlink,anchor,image,cleanup,help,code,|,insertdate,inserttime,|,forecolor,backcolor,|,charmap,iespell,media,advhr", theme_advanced_layout_manager : "SimpleLayout", theme_advanced_buttons3 : "tablecontrols,|,hr,removeformat,visualaid,|,sub,sup,strikethrough", theme_advanced_buttons4 : "styleselect,formatselect,fontselect,fontsizeselect,|,undo,redo,|,spellchecker", theme_advanced_toolbar_location : "external", theme_advanced_toolbar_align : "left", theme_advanced_statusbar_location : "bottom", relative_urls : true, document_base_url : "http://devtom.ecitb.org.uk/", auto_resize : true, content_css : "/custom/css/style.css", extended_valid_elements : "iframe[height|width|src|frameborder|scrolling]", }); /* The following code comes from- http://tinymce.moxiecode.com/punbb/viewtopic.php?id=12966 Without it the editor only loads 10% of the time.

• StreamReader.EndOfStream produces IOException

  - by Ziplin

  I'm working on an application that accepts TCP connections and reads in data until an </File> marker is read and then writes that data to the filesystem. I don't want to disconnect, I want to let the client sending the data to do that so they can send multiple files in one connection. I'm using the StreamReader.EndOfStream around my outter loop, but it throws an IOException when the client disconnects. Is there a better way to do this? private static void RecieveAsyncStream(IAsyncResult ar) { TcpListener listener = (TcpListener)ar.AsyncState; TcpClient client = listener.EndAcceptTcpClient(ar); // init the streams NetworkStream netStream = client.GetStream(); StreamReader streamReader = new StreamReader(netStream); StreamWriter streamWriter = new StreamWriter(netStream); while (!streamReader.EndOfStream) // throws IOException { string file= ""; while (file!= "</File>" && !streamReader.EndOfStream) { file += streamReader.ReadLine(); } // write file to filesystem } listener.BeginAcceptTcpClient(RecieveAsyncStream, listener); }

• Applet panels, one fixed size, and dynamic JTextField

• 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!

• git clone fails with "index-pack" failed?

  - by gct

  So I created a remote repo that's not bare (because I need redmine to be able to read it), and it's set to be shared with the group (so git init --shared=group). I was able to push to the remote repo and now I'm trying to clone it. If I clone it over the net I get this: remote: Counting objects: 4648, done. remote: Compressing objects: 100% (2837/2837), done. error: git-upload-pack: git-pack-objects died with error.B/s fatal: git-upload-pack: aborting due to possible repository corruption on the remote side. remote: aborting due to possible repository corruption on the remote side. fatal: early EOF fatal: index-pack failed I'm able to clone it locally without a problem, and I ran "git fsck", which only reports some dangling trees/blobs, which I understand aren't a problem. What could be causing this? I'm still able to pull from it, just not clone. I should note the remote git version is 1.5.6.5 while local is 1.6.0.4 I tried cloning my local copy of the repo, stripping out the .git folder and pushing to a new repo, then cloning the new repo and I get the same error, which leads me to believe it may be a file in the repo that's causing git-upload-pack to fail... Edit: I have a number of windows binaries in the repo, because I just built the python modules and then stuck them in there so everyone else didn't have to build them as well. If I remove the windows binaries and push to a new repo, I can clone again, perhaps that gives a clue. Trying to narrow down exactly what file is causing the problem now.

• Django - The included urlconf doesn't have any patterns in it

  - by unsorted

  My website, which was working before, suddenly started breaking with the error "ImproperlyConfigured at / The included urlconf resume.urls doesn't have any patterns in it" The project base is called resume. In settings.py I have set ROOT_URLCONF = 'resume.urls' Here's my resume.urls, which sits in the project root directory. from django.conf.urls.defaults import * # Uncomment the next two lines to enable the admin: from django.contrib import admin admin.autodiscover() urlpatterns = patterns('', # Example: # (r'^resume/', include('resume.foo.urls')), # Uncomment the admin/doc line below and add 'django.contrib.admindocs' # to INSTALLED_APPS to enable admin documentation: (r'^admin/doc/', include('django.contrib.admindocs.urls')), # Uncomment the next line to enable the admin: (r'^admin/', include(admin.site.urls)), (r'^accounts/login/$', 'django.contrib.auth.views.login'), #(r'^employer/', include(students.urls)), (r'^ajax/', include('urls.ajax')), (r'^student/', include('students.urls')), (r'^club/(?P<object_id>\d+)/$', 'resume.students.views.club_detail'), (r'^company/(?P<object_id>\d+)/$', 'resume.students.views.company_detail'), (r'^program/(?P<object_id>\d+)/$', 'resume.students.views.program_detail'), (r'^course/(?P<object_id>\d+)/$', 'resume.students.views.course_detail'), (r'^career/(?P<object_id>\d+)/$', 'resume.students.views.career_detail'), (r'^site_media/(?P<path>.*)$', 'django.views.static.serve', {'document_root': 'C:/code/django/resume/media'}), ) I have a folder called urls and a file ajax.py inside. (I also created a blank init.py in the same folder so that urls would be recognized.) This is ajax.py. from django.conf.urls.defaults import * urlpatterns = patterns('', (r'^star/(?P<object_id>\d+)$', 'resume.students.ajax-calls.star'), ) Anyone know what's wrong? This is driving me crazy. Thanks,

• Zend_Form using subforms getValues() problem

  - by wiseguydigital

  Hi all, I am building a form in Zend Framework 1.9 using subforms as well as Zend_JQuery being enabled on those forms. The form itself is fine and all the error checking etc is working as normal. But the issue I am having is that when I'm trying to retrieve the values in my controller, I'm receiving just the form entry for the last subform e.g. My master form class (abbreviated for speed): Master_Form extends Zend_Form { public function init() { ZendX_JQuery::enableForm($this); $this->setAction('actioninhere') ... ->setAttrib('id', 'mainForm') $sub_one = new Form_One(); $sub_one->setDecorators(... in here I add the jQuery as per the docs); $this->addSubForm($sub_one, 'form-one'); $sub_two = new Form_Two(); $sub_two->setDecorators(... in here I add the jQuery as per the docs); $this->addSubForm($sub_two, 'form-two'); } } So that all works as it should in the display and when I submit without filling in the required values, the correct errors are returned. However, in my controller I have this: class My_Controller extends Zend_Controller_Action { public function createAction() { $request = $this->getRequest(); $form = new Master_Form(); if ($request->isPost()) { if ($form->isValid($request->getPost()) { // This is where I am having the problems print_r($form->getValues()); } } } } When I submit this and it gets past isValid(), the $form-getValues() is only returning the elements from the second subform, not the entire form.

• 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.
