  • Having py2exe include my data files (like include_package_data)

    - by cool-RR
    I have a Python app which includes non-Python data files in some of its subpackages. I've been using the include_package_data option in my setup.py to include all these files automatically when making distributions. It works well. Now I'm starting to use py2exe. I expected it to see that I have include_package_data=True and to include all the files. But it doesn't. It puts only my Python files in the library.zip, so my app doesn't work. How do I make py2exe include my data files?

  • EXC_BAD_ACCESS when executing ABAddressBookSave !

    - by Horatiu Paraschiv
    Hi everybody, I'm trying to create a new contact and add it to the AddressBook but when I get to the ABAddressSave line of code I get EXC_BAD_ACCESS. I cannot see what am I doing wrong, I enabled NSZombie to check if this is a memory related error but it didn't spot any. Can anybody tell me what is wrong with this code? Thank you in advance! CFErrorRef error = NULL; ABAddressBookRef iPhoneAddressBook = ABAddressBookCreate(); ABRecordRef newRecord = ABPersonCreate(); ABRecordSetValue(newRecord, kABPersonFirstNameProperty, @"Xxxxxx", &error); ABRecordSetValue(newRecord, kABPersonURLProperty, @"Yyyyyy", &error); //Add phone numbers to record ABMutableMultiValueRef phones = ABMultiValueCreateMutable(kABMultiStringPropertyType); ABMultiValueAddValueAndLabel(phones, @"1-555-555-5555", kABWorkLabel, NULL); ABRecordSetValue(newRecord, kABPersonPhoneProperty, phones, &error); CFRelease(phones); //Add email address to record ABMutableMultiValueRef emails = ABMultiValueCreateMutable(kABMultiStringPropertyType); ABMultiValueAddValueAndLabel(emails, @"[email protected]", kABWorkLabel, NULL); ABRecordSetValue(newRecord, kABPersonEmailProperty, emails, &error); CFRelease(emails); ABMutableMultiValueRef multiAddress = ABMultiValueCreateMutable(kABMultiDictionaryPropertyType); NSMutableDictionary *addressDict = [[NSMutableDictionary alloc] init]; [addressDict setObject:@"xxx1" forKey:(NSString *)kABPersonAddressStreetKey]; [addressDict setObject:@"xxx2" forKey:(NSString *)kABPersonAddressCityKey]; [addressDict setObject:@"xxx3" forKey:(NSString *)kABPersonAddressStateKey]; [addressDict setObject:@"xxx4" forKey:(NSString *)kABPersonAddressZIPKey]; ABMultiValueAddValueAndLabel(multiAddress, addressDict, kABWorkLabel, NULL); ABRecordSetValue(newRecord, kABPersonAddressProperty, multiAddress, &error); CFRelease(multiAddress); [addressDict release]; ABAddressBookAddRecord(iPhoneAddressBook, newRecord, &error); ABAddressBookSave(iPhoneAddressBook, NULL); if(error != nil){ NSLog(@"Error creating contact:%@", error); }

  • [Cocoa] CoreData bindings for NSPopupButton

    - by ndg
    I'm looking to use a dropdown menu (possibly an NSPopupButton object) to represent the hierarchical results of two Core Data entities (Genre and Movie) and their relationships. In my current data model, my Genre entity has a one-to-many relationship with my Movie entity. What I'm now looking to do is generate the contents of an NSPopupButton to show a hierarchical list of Genres and the Movies associated with them, like so: Genre 1 Film 1 Film 2 Genre 2 Film 3 Film 4 Note that, in the above example, only Movie objects are to be selectable by the user (Genre objects will appear, but be unselectable). Also, to complicate matters slightly, I have an additional NSPopupButton which lists Movie Rental locations. The location selected by the user ultimately impacts on the genres and films available in the second dropdown. I imagine that bindings will only take me so far with this problem and that, ultimately, I'll have to populate the contents of the dropdown menu myself. I'm posting here for thoughts and opinions on the best way to go about this.

  • Silverlight 4 - encoding PCM data from the microphone

    - by Richard
    Hi I've written a basic SL4 application to capture audio data from the microphone using CaptureSource. The trouble is, it's raw PCM output - which means huge and uncompressed. Given that I need this application to run purely within a SL4 environment, how can I compress the PCM audio data into something that can be delivered to a remote server more easily? In conversation, people have suggested Speex and WMA for instance, but I haven't found any libraries or examples that work without requiring reference to DLL's that won't work in a SL4 project. Thanks, Richard.

  • Asp.Net MVC - Blank model not returning blank data

    - by Pino
    I have a form which a user can fill in x times with the data they want too. The form is posted to the following Action. [HttpPost] public ActionResult Manage(ProductOptionModel DataToAdd) { if (!ModelState.IsValid) { return View(DataToAdd); } var ProdServ = new ProductService(); if (DataToAdd.ID != 0) { //Edit Mode. DataToAdd = ProdServ.EditProductOption(DataToAdd); ViewData["Message"] = "Option Changes Made"; }else { //Add DataToAdd = ProdServ.AddProductOption(DataToAdd); ViewData["Message"] = "New Option Added"; } var RetModel = new ProductOptionModel() {ProductID = DataToAdd.ProductID}; return View(RetModel); } So at the bottom I blank the model (Leaving just the required field) and then return to the view. However the view holds the data from the previously submitted form. Any ideas why? I have debugged the code and checked that the RetModel variable is empty.

  • May a NSManagedObjectContext re-fault objects automatically?

    - by frenetisch applaudierend
    I am trying to create an application which allows background threads to update core data objects while the user might be reading the same data. My approach to this would be to use multiple NSManagedObjectContexts and then before a background thread does a -save: operation, I fetch the object the user is currently working on and fire the fault for all its properties and relationships recursively. This way I have all objects the user could act with in my NSManagedObjectContext without seeing the already updated values. But this can only work if the NSManagedObjectContext cannot decide himself that e.g. memory usage is too high, and starts faulting objects which I do not explicitly reference (other than through the NSManagedObject relationship). So the question is, can the NSManagedObjectContext decide that an object needs to be re-faulted, without intervention from my side? Thanks for your effort, Markus

  • WPF - Binding a color resource to the data object within a DataTemplate

    - by John
    I have a DataTemplate and a SolidColorBrush in the DataTemplate.Resources section. I want to bind the color to a property of the same data object that the DataTemplate itself is bound to. However, this does not work. The brush is ignored. Why? <DataTemplate DataType="{x:Type data:MyData}" x:Name="dtData"> <DataTemplate.Resources> <SolidColorBrush x:Key="bg" Color="{Binding Path=Color, Converter={StaticResource colorConverter}" /> </DataTemplate.Resources> <Border CornerRadius="15" Background="{StaticResource bg}" Margin="0" Opacity="0.5" Focusable="True"> </DataTemplate>

  • Read and write from a byte stream if the endianess of the data is different from that of the current

    - by Sam Holder
    I have a stream of bytes which contains a flag which identifies the endianness of the data in the header. I want to read the doubles from the stream, which will presumably need to be different if the endianness of the data in the header is different? I am currently using a BinaryReader and calling ReadDouble to read the data from the stream, but if the endianness flag indicates that the data stream has a different endianness than the machine architecture then presumably this will not work? How should this be handled? Should I check the endianness of my data against that of the current machine then when I want to read a double instead read the bytes raw into a byte array and do array.Reverse to reverse the data before using BitConverter.ToDouble () with the reversed data and a zero offset? I could just test this but I do not have a source of data for both endianness so am a bit concerned about creating test data to test the parsing and this being different from what 'real' data might look like.

  • How do you prevent brute force attacks on RESTful data services

    - by Adrian Grigore
    Hi, I'm about to implement an RESTful API to our website (based on WCF data services, but that probably does not matter). All data offered via this API belongs to certain users of my server, so I need to make sure only those users have access to my resources. For this reason, all requests have to be performed with a login/password combination as part of the request. What's the recommended approach for preventing brute force attacks in this scenario? I was thinking of logging failed requests denied due to wrong credentials and ignoring requests originating from the same IP after a certain threshold of failed requests has been exceeded. Is this the standard approach, or am I a missing something important? Thanks, Adrian

  • SQL Server 2000 tables

    - by klork
    We currently have an SQL Server 2000 database with one table containing data for multiple users. The data is keyed by memberid which is an integer field. The table has a clustered index on memberid. The table is now about 200 million rows. Indexing and maintenance are becoming issues. We are debating splitting the table into one table per user model. This would imply that we would end up with a very large number of tables potentially upto the 2,147,483,647, considering just positive values. My questions: Does anyone have any experience with a SQL Server (2000/2005) installation with millions of tables? What are the implications of this architecture with regards to maintenance and access using Query Analyzer, Enterprise Manager etc. What are the implications to having such a large number of indexes in a database instance. All comments are appreciated. Thanks

  • AVAudioPlayer crash after playing from an AVAudioRecorder

    - by munchine
    I've got a button the user tap to start recording and tap again to stop. When it stop I want the recorded voice 'echo' back so the user can hear what was recorded. This works fine the first time. If I hit the button for the third time, it starts a new recording and when I hit stop it crashes with EXC_BAD_ACCESS. - (IBAction) readToMeTapped { if(recording) { recording = NO; [readToMeButton setTitle:@"Stop Recording" forState: UIControlStateNormal ]; NSMutableDictionary *recordSetting = [[NSDictionary alloc] initWithObjectsAndKeys: [NSNumber numberWithFloat: 44100.0], AVSampleRateKey, [NSNumber numberWithInt: kAudioFormatAppleLossless], AVFormatIDKey, [NSNumber numberWithInt: 1], AVNumberOfChannelsKey, [NSNumber numberWithInt: AVAudioQualityMax], AVEncoderAudioQualityKey, nil]; // Create a new dated file NSDate *now = [NSDate dateWithTimeIntervalSinceNow:0]; NSString *caldate = [now description]; recordedTmpFile = [NSURL fileURLWithPath:[[NSString stringWithFormat:@"%@/%@.caf", DOCUMENTS_FOLDER, caldate] retain]]; error = nil; recorder = [[ AVAudioRecorder alloc] initWithURL:recordedTmpFile settings:recordSetting error:&error]; [recordSetting release]; if(!recorder){ NSLog(@"recorder: %@ %d %@", [error domain], [error code], [[error userInfo] description]); UIAlertView *alert = [[UIAlertView alloc] initWithTitle: @"Warning" message: [error localizedDescription] delegate: nil cancelButtonTitle:@"OK" otherButtonTitles:nil]; [alert show]; [alert release]; return; } NSLog(@"Using File called: %@",recordedTmpFile); //Setup the recorder to use this file and record to it.

I thought it may have something to do with releasing memory but I've been careful. Have I missed something?

  • NSZombieEnabled breaking working code?

    - by Gordon Fontenot
    I have the following method in UIImageManipulation.m: +(UIImage *)scaleImage:(UIImage *)source toSize:(CGSize)size { UIImage *scaledImage = nil; if (source != nil) { UIGraphicsBeginImageContext(size); [source drawInRect:CGRectMake(0, 0, size.width, size.height)]; scaledImage = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); } return scaledImage; } I am calling it in a different view with: imageFromFile = [UIImageManipulator scaleImage:imageFromFile toSize:imageView.frame.size]; (imageView is a UIImageView allocated earlier) This is working great in my code. I resizes the image perfectly, and throws zero errors. I also don't have anything pop up under build - analyze. But the second I turn on NSZombieEnabled to debug a different EXC_BAD_ACCESS issue, the code breaks. Every single time. I can turn NSZombieEnabled off, code runs great. I turn it on, and boom. Broken. I comment out the call, and it works again. Every single time, it gives me an error in the console: -[UIImage release]: message sent to deallocated instance 0x3b1d600. This error doesn't appear if `NSZombieEnabled is turned off. Any ideas? --EDIT-- Ok, This is killing me. I have stuck breakpoints everywhere I can, and I still cannot get a hold of this thing. Here is the full code when I call the scaleImage method: -(void)setupImageButton { UIImage *imageFromFile; if (object.imageAttribute == nil) { imageFromFile = [UIImage imageNamed:@"no-image.png"]; } else { imageFromFile = object.imageAttribute; } UIImage *scaledImage = [UIImageManipulator scaleImage:imageFromFile toSize:imageButton.frame.size]; UIImage *roundedImage = [UIImageManipulator makeRoundCornerImage:scaledImage :10 :10 withBorder:YES]; [imageButton setBackgroundImage:roundedImage forState:UIControlStateNormal]; } The other UIImageManipulator method (makeRoundCornerImage) shouldn't be causing the error, but just in case I'm overlooking something, I threw the entire file up on github here. It's something about this method though. Has to be. If I comment it out, it works great. If I leave it in, Error. But it doesn't throw errors with NSZombieEnabled turned off ever.

  • Consolidate data from many different databases into one with minimum latency

    - by NTDLS
    I have 12 databases totaling roughly 1.0TB, each on a different physical server running SQL 2005 Enterprise - all with the same exact schema. I need to offload this data into a separate single database so that we can use for other purposes (reporting, web services, ect) with a maximum of 1 hour latency. It should also be noted that these servers are all in the same rack, connected by gigabit connections and that the inserts to the databases are minimal (Avg. 2500 records/hour). The current method is very flakey: The data is currently being replicated (SQL Server Transactional Replication) from each of the 12 servers to a database on another server (yes, 12 different employee tables from 12 different servers into a single employee table on a different server). Every table has a primary key and the rows are unique across all tables (there is a FacilityID in each table). What are my options, these has to be a simple way to do this.

  • What are the best measures to protect content from being crawled?

    - by Moak
    I've been crawling a lot of websites for content recently and am surprised how no site so far was able to put up much resistance. Ideally the site I'm working on should not be able to be harvested so easily. So I was wondering what are the best methods to stop bots from harvesting your web content. Obvious solutions: Robots.txt (yea right) IP blacklists What can be done to catch bot activity? What can be done to make data extraction difficult? What can be done to give them crap data? Just looking for ideas, no right/wrong answer

  • Birt 2.5.2 report generates empty table data when run from a cron job

    - by Trueblood
    I've got a shell script that runs genReport.sh in order to create a .pdf formatted report, and it works perfectly when it's run from the command line. The data source for the report is a ClearQuest database. When it's run from a CRON job the .pdf file is created, except that only the various report and column headers are displayed, and the data of the report is missing. There are no errors reported to STDERR during the execution of the script. This screams "environment variable" to me. Currently, the shell script is defining the following: CQ_HOME BIRT_HOME ODBCINI ODBCINST LD_LIBRARY_PATH If it's an environmental thing, what part of the environment am I missing?

  • Pass array of data to jQuery function

    - by ILMV
    Here's the story... I have a jQuery function that does something, this function is referenced very regularly. One of the input parameters is an array, this array data is hard coded and thus I want to pass the data like this: (this is how I would do it using PHP) myFunction(Array("1"=>"a","2"=>"b","3"=>"c")); Instead of $arr=Array("1"=>"a","2"=>"b","3"=>"c"); myFunction($arr); So how do I achieve this with my jQuery function, I want this to be a one liner if possible.

  • EXEC_BAD_ACCESS in UITableView cellForRowAtIndexPath

    - by David van Dugteren
    My UITable is returning EXEC_BAD_ACCESS, but why! See this code snippet! Loading the UITableView works fine, so allXYZArray != nil and is populated! Then scrolling the tableview to the bottom and back up causes it to crash, as it goes to reload the method cellForRowAtIndexPath It fails on line: "NSLog(@"allXYZArray::count: %i", [allXYZArray count]);" - (UITableViewCell *)tableView:(UITableView *)theTableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"CellIdentifier"; UITableViewCell *cell = [theTableView dequeueReusableCellWithIdentifier:CellIdentifier]; cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; @try { if (allAdviceArray == nil) { NSLog(@"nil"); allXYZArray = [ToolBox getMergedSortedDictionaries:allXYZGiven SecondDictionary:allXYZSought]; } NSLog(@"%i", [indexPath row]); NSLog(@"allXYZArray::count: %i", [allXYZArray count]);

  • Break on EXC_BAD_ACCESS in XCode?

    - by jasonh
    I'm new to iPhone development and XCode in general and have no idea how to begin troubleshooting an EXC_BAD_ACCESS signal. How can I get XCode to break at the exact line that is causing the error? I can't seem to get XCode to stop on the line causing the problem, but I do see the following lines in my debug console: Sun Oct 25 15:12:14 jasonsmacbook TestProject[1289] : CGContextSetStrokeColorWithColor: invalid context Sun Oct 25 15:12:14 jasonsmacbook TestProject[1289] : CGContextSetLineWidth: invalid context Sun Oct 25 15:12:14 jasonsmacbook TestProject[1289] : CGContextAddPath: invalid context Sun Oct 25 15:12:14 jasonsmacbook TestProject[1289] : CGContextDrawPath: invalid context 2009-10-25 15:12:14.680 LanderTest[1289:207] *** -[CFArray objectAtIndex:]: message sent to deallocated instance 0x3c4e610 Now, I am attempting to draw to the context I retrieve from UIGraphicsGetCurrentContext() and pass to the object that I want to draw with. Further trial and error debugging and I found that an NSMutableArray I have a property for on my class was a zombie. I went into the init function for the class and here's the code I was using: if ((self = [super init])) { NSMutableArray *array = [NSMutableArray array]; self.terrainBlocks = array; [array release]; } return self; } I removed the [array release] line and it no longer gives me the EXC_BAD_ACCESS signal, but I'm now confused about why this works. I thought that when I used the property, it automatically retained it for me, and thus I should release it from within init so that I don't have a leak. I'm thoroughly confused about how this works and all the guides and Stackoverflow questions I've read only confuse me more about how to set properties within my init method. There seems to be no consensus as to which way is the best.

  • Avoiding EXC_BAD_ACCESS when using the delegate pattern

    - by Kenny Winker
    A have a view controller, and it creates a "downloader" object, which has a reference to the view controller (as a delegate). The downloader calls back the view controller if it successfully downloads the item. This works fine as long as you stay on the view, but if you navigate away before the download is complete I get EXC_BAD_ACCESS. I understand why this is happening, but is there any way to check if an object is still allocated? I tried to test using delegate != nil, and [delegate respondsToSelector:], but it chokes. if (!self.delegate || ![self.delegate respondsToSelector:@selector(downloadComplete:)]) { // delegate is gone, go away quietly [self autorelease]; return; } else { // delegate is still around [self.delegate downloadComplete:result]; } I know I could, a) have the downloader objects retain the view controller b) keep an array of downloaders in the view controller, and set their delegate values to nil when I deallocate the view controller. But I wonder if there is an easier way, where I just test if the delegate address contains a valid object?

  • How to reserve a set of primary key identifiers for preloading bootstrap data

    - by Joshua
    We would like to reserve a set of primary key identifiers for all tables (e.g. 1-1000) so that we can bootstrap the system with pre-loaded system data. All our JPA entity classes have the following definition for the primary key. @Id @GeneratedValue(strategy = IDENTITY) @Column(name = "id", unique = true, nullable = false, insertable = false, updatable = false) private Integer id; is there a way to tell the database that increments should start happening from 1000 (i.e. customer specific data will start from 1000 onwards). We support (h2, mysql, postgres) in our environment and I would prefer a solution which can be driven via JPA and reverse engineering DDL tools from Hibernate. Let me know if this is the correct approach
