  • How to speed up saving a UIImagePickerController image from the camera to the filesystem via UIImagePNGRepresentation()?

    - by kazuhito0000
    I'm making an applications that let users take a photo and show them both in thumbnail and photo viewer. I have NSManagedObject class called photo and photo has a method that takes UIImage and converts it to PNG using UIImagePNGRepresentation() and saves it to filesystem. After this operation, resize the image to thumbnail size and save it. The problem here is UIImagePNGRepresentation() and conversion of image size seems to be really slow and I don't know if this is a right way to do it. Tell me if anyone know the best way to accomplish what I want to do. Thank you in advance.

  • How to return a copy of the data in C++

    - by Josh Curren
    I am trying to return a new copy of the data in a C++ Template class. The following code is getting this error: invalid conversion from ‘int*’ to ‘int’. If I remove the new T then I am not returning a copy of the data but a pointer to it. template<class T> T OrderedList<T>::get( int k ) { Node<T>* n = list; for( int i = 0; i < k; i++ ) { n=n->get_link(); } return new T( n->get_data() ); // This line is getting the error ********** }

  • C# overloading with generics: bug or feature?

    - by TN
    Let's have a following simplified example: void Foo<T>(IEnumerable<T> collection, params T[] items) { // ... } void Foo<C, T>(C collection, T item) where C : ICollection<T> { // ... } void Main() { Foo((IEnumerable<int>)new[] { 1 }, 2); } Compiler says: The type 'System.Collections.Generic.IEnumerable' cannot be used as type parameter 'C' in the generic type or method 'UserQuery.Foo(C, T)'. There is no implicit reference conversion from 'System.Collections.Generic.IEnumerable' to 'System.Collections.Generic.ICollection'. If I change Main to: void Main() { Foo<int>((IEnumerable<int>)new[] { 1 }, 2); } It will work ok. Why compiler does not choose the right overload?

  • MySQL pivot tables - covert rows to columns

    - by user2723490
    This is the structure of my table: Then I run a query SELECT `date`,`index_name`,`results` FROM `mst_ind` WHERE `index_name` IN ('MSCI EAFE Mid NR USD', 'Alerian MLP PR USD') AND `time_period`='M1' and get a table like How can I convert "index_name" rows to columns like: date | MSCI EAFE Mid NR USD | Alerian MLP PR USD etc In other words I need each column to represent an index and rows to represent date-result. I understand that MySQL doesn't have pivot table functions. What is the easiest way of doing this? I've tried this code, but it generates an error: SELECT `date`, MAX(IF(index_name = 'Alerian MLP PR USD' AND `time_period`='M1', results, NULL)) AS res1, MAX(IF(index_name = 'MSCI EAFE Mid NR USD' AND `time_period`='M1', results, NULL)) AS res2 FROM `mst_ind` GROUP BY `date I need to make the conversion on the query level - not PHP. Please suggest a nice and elegant solution. Thanks!

  • Formatting dates when serialising an object in C# (2.0)

    - by zoman
    Hi, I'm xml-serializing a object with a large number of properties and I have two properties with DateTime types. I'd like to format the dates for the serialized output. I don't really want to implement the ISerializable interface and overwrite the serialization for every property. Is there any other way to achieve this? (I'm using C#, .NET 2) Thanks.

  • What is the most robust way of determining the current codepage from a shell script?

    - by rewbs
    Hi all, I'd like to determine the environment's current codepage at runtime from a Unix shell script. What's the most reliable way of doing this? I'm looking into parsing environment variable $LC_ALL, but it isn't always set to a useful value, and its format seems to vary (can be <locale, or <locale.<code page, or <locale.<code page@<modifier etc...). Is there a better way? I'm essentially after a shell equivalent of what I'd get if I called nl_langinfo(CODESET) from C.

  • Has anyone used Sphinx to document a C++ project?

    - by Nick
    Sphinx is a new documentation tool for Python. It looks very nice. What I'm wondering is: How suitable this is for documenting a C++ project? Are there any tools for converting existing documentation (e.g. doxygen) to Sphinx format? Are there online/downloadable examples of C++ projects that use Sphinx? Any tips from anyone who has used Sphinx?

  • C++ enum casting and templates

    - by JP
    I get the following error with VS2008: Conversion to enumeration type requires an explicit cast (static_cast, C-style cast or function-style cast) When casting a down casting a ClassA to ClassA_1 and ClassA_1 is a templated class that received an enum for parameter such as: ClassA { virtual ~ClassA(){}; } template <class Param1> ClassA_1 : public ClassA { public: //constructor ClassA_1(Param1 p1) { _p1 = p1; } Param1 _p1; } So I have a upcasted ClassA a = new ClassA_1<myenum>(); When I need to do this: ClassA_1<myenum> a1 = (ClassA_1<myenum> a); // This fails ... The only way it works is: ClassA_1<int> a1 = (ClassA_1<int> a); but this break my template as it must always deal with int... How to properly cast a enum that is now a int, back into the enum?

  • Looking for a script/tool to dump a list of installed features and programs on Windows Server 2008 R

    - by Hamish Grubijan
    Hi, The same compiled .Net / C++ / Com program does different things on two seemingly same computers. Both have DOZENS of things installed on them. I would like to figure out what the difference between the two is by looking at an ASCII diff. Before that I need to "serialize" the list of installed things in a plain readable format - sorted alphabetically + one item per line. A Python script would be ideal, but I also have Perl, PowerShell installed. Thank you.

  • Can't add an object using EF and SQL Compact

    - by kamilo
    Hello, I have some very simple SQL Compact database. I would like to use Entity Framework to access the database but for some reason I can't add an object to this database using EF. Here is the code using (pos_inglotEntities posInglotCtx = new pos_inglotEntities()) { posInglotCtx.Connection.Open(); CT_POS_OITM item = new CT_POS_OITM() { ItemCode = "123", ItemName="abc"}; try { posInglotCtx.AddToCT_POS_OITM(item); posInglotCtx.SaveChanges(); } catch (Exception e) { } posInglotCtx.Connection.Close(); } After running this code my database is still empty although if I run it once again I get "duplicate values" exception. But again database is empty. I created this db using PrimeWorks conversion tool from standard sql server database. What is going on? Thanks in advance
