  • Android equivalent work-around for View.getX() before API 11?

    - by user48998
    I'm using the getX() and getY() method on a view for some special dragging logic (not animation, i.e. I never use setX/Y methods, I just need the getters to check). However, I've come to realize that these are only available post-API 11. The docs for getX() say that is it the addition of the 'left' property and the 'translationX' property. All well and good, except get/setTranslationX() is only around since API 11 as well. I was wondering if there was any knowledge on what this method returns behind the scenes, so I could maybe put in a workaround. Thanks for any help - Chase

  • How can I implement a jquery ajax form which requests information from a web api via a php request?

    - by Jacob Schweitzer
    I'm trying to implement a simple api request to the SEOmoz linkscape api. It works if I only use the php file but I want to do an ajax request using jquery to make it faster and more user friendly. Here is the javascript code I'm trying to use: $(document).ready(function(){ $('#submit').click(function() { var url=$('#url').val(); $.ajax({ type: "POST", url: "api_sample.php", data: url, cache: false, success: function(html){ $("#results").append(html); } }); }); }); And here is the part of the php file where it takes the value: $objectURL = $_POST['url']; I've been working on it all day and can't seem to find the answer... I know the php code works as it returns a valid json object and displays correctly when I do it that way. I just can't get the ajax to show anything at all!!

  • Has anyone managed to get Visual Studio 2003 running on Windows 7?

    - by Jeremy White
    Yes, I know... I could set up a virtual machine running XP. Unfortunately our build environment is such that we need to be running VC2003, 2005 and 2008 concurrently and it would be much more convenient if I could run 2003 natively on Windows 7 for the few projects we have that require it. I realize some things may not be available in the IDE, but I was able to run 2003 under windows Vista and if I could get the same base level of functionality under Windows 7 I would be extremely happy. Right now I get an error opening the *.pdb file when I compile after switching vc2003 to run as Administrator under compatibility mode for XP SP 2. Thanks!

  • If I create a transient property in the model, isn't this managed by core data then?

    - by mystify
    Just to grok this: If I had a transient property, lets say averagePrice, and I mark that as "transient" in the data modeler: This will not be persistet, and no column will be created in SQLite for that? And: If I make my own NSManagedObject subclass with an averagePrice property, does it make any sense to model that property in the xcdatamodel file? Would it make a difference if I would simply create a property in my subclass and not model that in the entity? (I think: yes, it doesn't matter at all ... but not sure)

  • How can I edit an incoming text message (sms) as it arrives in windows mobile 6 using managed code

    - by x86shadow
    I want to make an application for pocket PCs to send and receive Encrypted text messages. I have already made an application that gets special text messages ( starting with !farenc! ) and I know how to Encrypt/Decrypt the messages as well. The problem is that I don't know how to edit a text message after it's arrived (for decryption). See code below for more info. using System; using System.Linq; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Text; using System.Windows.Forms; using Microsoft.WindowsMobile; using Microsoft.WindowsMobile.PocketOutlook; using Microsoft.WindowsMobile.PocketOutlook.MessageInterception; namespace SMSDECRYPT { public partial class Form1 : Form { MessageInterceptor _SMSCatcher = new MessageInterceptor(InterceptionAction.Notify, true); MessageCondition _SMSFilter = new MessageCondition(); public Form1() { InitializeComponent(); _SMSFilter.Property = MessageProperty.Body; _SMSFilter.ComparisonType = MessagePropertyComparisonType.StartsWith; _SMSFilter.CaseSensitive = true; _SMSFilter.ComparisonValue = "!farenc!"; _SMSCatcher.MessageCondition = _SMSFilter; _SMSCatcher.MessageReceived += new MessageInterceptorEventHandler(_SMSCatcher_MessageReceived); } private void Form1_Load(object sender, EventArgs e) { //... } void _SMSCatcher_MessageReceived(object sender, MessageInterceptorEventArgs e) { SmsMessage mySMS = (SmsMessage)e.Message; string sms = mySMS.Body.ToString(); sms = sms.Substring(8); //Decryption //... //Update the received message and replace it with the decrypted text //!!!HELP!!! } } }

  • Why are there so many floats in the Android API?

    - by Brian
    The default floating point type in Java is the double. If you hard code a constant like 2.5 into your program, Java makes it a double automatically. When you do an operation on floats or ints that could potentially benefit from more precision, the type is 'promoted' to a double. But in the Android API, everything seems to be a float from sound volumes to rectangle coordinates. There's a structure called RectF used in most drawing; the F is for float. It's really a pain for programmers who are casting promoted doubles back to (float) pretty often. Don't we all agree that Java code is messy and verbose enough as it is? Usually math coprocessors and accelerators prefer double in Java because it corresponds to one of the internal types. Is there something about Android's Dalvik VM that prefers floats for some reason? Or are all the floats just a result of perversion in API design?

  • Is Classic ADO still viable for a mixed managed/unmanaged App?

    - by Andy Dent
    We have a complex architecture with much logic in unmanaged code that needs database access. Currently this is via ODBC drivers and MFC classes and we're considering the issues of migrating our abstraction layer to use ADO or ADO.Net. In the latter case we'd have to be pushing database logic back up into the .Net layer. I'm trying to decide if the pain of invoking the database via .Net callbacks is offset by the improvements in ADO.Net. The Wikipedia comparison was interesting although I'm not sure I believe all the points in the comparison table (eg: does ADO.Net always use XML to pass data?). A 2005 comparison shows ADO.Net performing dramatically faster. Microsoft's guide to ADO.Net for ADO programmers suggests we will gain much from going to ADO.Net especially the way that data is available in native (.Net) types rather than solely through OLEAutomation's Variant.

  • Managed HttpListener vs C++ Network Lib - Requires admin rights?

    - by Max
    So, I have noticed that starting an HttpListener is considered impolite according to Win 7. I cannot do so without administrative rights without adding myself to some URL reservation list. In theory, this is alright, but I'd like to make my program as little invasive as possible. My main other alternative is something like the c++ Network Library, which utilizes boost. This is probably not as simple as a HttpListener though. Will this circumvent the admin rights requirement for listening to some HTTP url? How does windows handle http listening? Right now I'm just listening to http://+:xxxx/url, I guess it's fully possible to just create a Socket listening at port xxxx and provide my own/third party http implementation?

  • Assigning two strings together getting Access Read Violation

    - by Jay Bell
    I am trying to pass a string to a class mutator and set the private member to that string here is the code that is sending the string void parseTradePairs(Exchange::Currency *curr, std::string *response, int begin, int exit) { int start; int end; string temp; string dataResponse; CURL *tempCurl; initializeCurl(tempCurl); int location = response->find("marketid", begin); if(location <= exit) { start = location + 11; begin = response->find("label", start); end = begin - start - 3; findStrings(start, end, temp, response); getMarketInfo(tempCurl, temp, dataResponse); curr->_coin->setExch(temp); // here is the line of code that is sending the string dataResponse >> *(curr->_coin); curr->_next = new Exchange::Currency(curr, curr->_position + 1); parseTradePairs(curr->_next, response, begin, exit); } } and here is the mutator within the coin class that is receiving the string and assigning it to _exch void Coin::setExch(string exch) { _exch = exch; } I have stepped through it and made sure that exch has the string in it. "105" but soon as it hits _exch = exch; I get the reading violation. I tried passing as pointer as well. I do not believe it should go out of scope. and the string variable in the class is initialized to zero in the default constructor but again that should matter unless I am trying to read from it instead of writing to it. /* defualt constructor */ Coin::Coin() { _id = ""; _label = ""; _code= ""; _name = ""; _marketCoin = ""; _volume = 0; _last = 0; _exch = ""; } Exchange::Exchange(std::string str) { _exch = str; _currencies = new Currency; std::string pair; std::string response; CURL *curl; initializeCurl(curl); getTradePairs(curl, response); int exit = response.find_last_of("marketid"); parseTradePairs(_currencies, &response, 0, exit); } int main(void) { CURL *curl; string str; string id; Coin coin1; initializeCurl(curl); Exchange ex("cryptsy"); curl_easy_cleanup(curl); system("pause"); return 0; } class Exchange { public: typedef struct Currency { Currency(Coin *coin, Currency *next, Currency *prev, int position) : _coin(coin), _next(next), _prev(prev), _position(position) {} Currency(Currency *prev, int position) : _prev(prev), _position(position), _next(NULL), _coin(&Coin()){} Currency() : _next(NULL), _prev(NULL), _position(0) {} Coin *_coin; Currency *_next; Currency *_prev; int _position; }; /* constructor and destructor */ Exchange(); Exchange(std::string str); ~Exchange(); /* Assignment operator */ Exchange& operator =(const Exchange& copyExchange); /* Parse Cryptsy Pairs */ friend void parseTradePairs(Currency *curr, std::string *response, int begin, int exit); private: std::string _exch; Currency *_currencies; }; here is what i changed it to to fix it. typedef struct Currency { Currency(Coin *coin, Currency *next, Currency *prev, int position) : _coin(coin), _next(next), _prev(prev), _position(position) {} Currency(Currency *prev, int position) : _prev(prev), _position(position), _next(NULL), _coin(&Coin()){} Currency() { _next = NULL; _prev = NULL; _position = 0; _coin = new Coin(); } Coin *_coin; Currency *_next; Currency *_prev; int _position; };

  • How are managed the sequences by JPA and Hibernate?

    - by romaintaz
    Hi all, I am using Hibernate in my project, and many of my entities use a sequence for their technical keys. For example: @Entity @Table(name = "T_MYENTITY") @SequenceGenerator(name = "S_MYENTITY", sequenceName = "S_MYENTITY") public class MyEntity { @Id @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "S_MYENTITY") @Column(name = "MY_ENTITY_ID") private Long entityId; ... } I have two questions about the ID generated by Hibernate when a new object of this class is persisted: Why SequenceGenerator (from javax.persistence) has a default value of allocationSize set to 50 instead of 1? What are the interests of that? What is the default algorithm used by Hibernate to calculate the generated ID? It seems that Hibernate uses the value returned by the sequence hosted by my Oracle database, but then modify it before assigning it to my entity...

  • Fail to save a managed object to core-data after its properties were updated.

    - by Tzur Gazit
    I have to trouble to create the object, but updating it fails. Here is the creation code: // Save data from pList to core data fro the first time - (void) saveToCoreData:(NSDictionary *)plistDictionary { // Create system parameter entity SystemParameters *systemParametersEntity = (SystemParameters *)[NSEntityDescription insertNewObjectForEntityForName:@"SystemParameters" inManagedObjectContext:mManagedObjectContext]; //// // GPS SIMULATOR //// NSDictionary *GpsSimulator = [plistDictionary valueForKey:@"GpsSimulator"]; [systemParametersEntity setMGpsSimulatorEnabled:[[GpsSimulator objectForKey:@"Enabled"] boolValue]]; [systemParametersEntity setMGpsSimulatorFileName:[GpsSimulator valueForKey:@"FileName"]]; [systemParametersEntity setMGpsSimulatorPlaybackSpeed:[[GpsSimulator objectForKey:@"PlaybackSpeed"] intValue]]; [self saveAction]; } During execution the cached copy is changed and then it is saved (or trying) to the database. Here is the code to save the changed copy: // Save data from pList to core data fro the first time - (void) saveSystemParametersToCoreData:(SystemParameters *)theSystemParameters { // Step 1: Select Data NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"SystemParameters" inManagedObjectContext:mManagedObjectContext]; [fetchRequest setEntity:entity]; NSError *error = nil; NSArray *items = [self.managedObjectContext executeFetchRequest:fetchRequest error:&error]; [fetchRequest release]; if (error) { NSLog(@"CoreData: saveSystemParametersToCoreData: Unresolved error %@, %@", error, [error userInfo]); abort(); } // Step 2: Update Object SystemParameters *systemParameters = [items objectAtIndex:0]; //// // GPS SIMULATOR //// [systemParameters setMGpsSimulatorEnabled:[theSystemParameters mGpsSimulatorEnabled]]; [systemParameters setMGpsSimulatorFileName:[theSystemParameters mGpsSimulatorFileName]]; [systemParameters setMGpsSimulatorPlaybackSpeed:[theSystemParameters mGpsSimulatorPlaybackSpeed]]; // Step 3: Save Updates [self saveAction]; } As to can see, I fetch the object that I want to update, change its values and save. Here is the saving code: - (void)saveAction { NSError *error; if (![[self mManagedObjectContext] save:&error]) { NSLog(@"ERROR:saveAction. Unresolved Core Data Save error %@, %@", error, [error userInfo]); exit(-1); } } The Persistent store method: - (NSPersistentStoreCoordinator *)persistentStoreCoordinator { if (mPersistentStoreCoordinator != nil) { return mPersistentStoreCoordinator; } NSString *path = [self databasePath]; NSURL *storeUrl = [NSURL fileURLWithPath:path]; NSError *error = nil; mPersistentStoreCoordinator = [[NSPersistentStoreCoordinator alloc] initWithManagedObjectModel:[self managedObjectModel]]; if (![mPersistentStoreCoordinator addPersistentStoreWithType:NSSQLiteStoreType configuration:nil URL:storeUrl options:nil error:&error]) { NSLog(@"Unresolved error %@, %@", error, [error userInfo]); abort(); } return mPersistentStoreCoordinator; } There is no error but the sqLite file is not updated, hence the data is not persistent. Thanks in advance.

  • How to get the line number an xml element is on via the Java w3c dom api

    - by Benju
    Is there a way to lookup the line number that a given element is at in an xml file via the w3c dom api? My use case for this is that we have 30,000+ maps in kml/xml format. I wrote a unit test that iterates over each file found on the hard drive (about 17GB worth) and tests that it is parseable by our application. When it fails I throw an exception that contains the element instance that was considered "invalid". In order for our mapping department (nobody here knows how to program) to easily track down the typo we would like to log the line number of the element that caused the exception. Can anybody suggest a way to do this? Please note we are using the W3C dom api included in the Android 1.6 SDK.

  • Using Google's Contacts API's, how can I get the user's name and gmail address?

    - by chris
    I know how to get the entire contacts list using Google Contacts API (I get a session token and use Google's Zend package for PHP). But how can I get the person's name and email address? Currently, the Contacts API just seems to give all of the contacts. I'm not sure how to distinguish which email and name out of that list corresponds to the user's account. Is there an easy way to get the user's full name and email address? Any help would be useful. Thanks!

  • Sinatra as backend (API) for Rails app or padrino or any hybrid solution?

    - by JVK
    Is it a good idea to build backend APIs in Sinatra for Rails app. Or is it better to use Padrino? I want to have my backend provides API as service, so that anytime, if I have to develop same app for any client, I can use that back-end API (web services). What is the best approach? My goal is to expose back-end as web services and even rails uses it for webapp. What are the disadvantages or advantage of different approaches?
