  • JPQL: What kind of objects contains a result list when querying multiple columns?

    - by Bunkerbewohner
    Hello! I'm trying to do something which is easy as pie in PHP & Co: SELECT COUNT(x) as numItems, AVG(y) as average, ... FROM Z In PHP I would get a simple array like [{ numItems: 0, average: 0 }] which I could use like this: echo "Number of Items: " . $result[0]['numItems']; Usually in JPQL you only query single objects or single columns and get Lists types, for example List or List. But what do you get, when querying multiple columns?

  • C error expected specifier-qualifier-list before ‘time_t’

    - by ambika
    I got the error from error.c:31: /usr/include/ap/mas.h:254: error: expected specifier-qualifier-list before ‘time_t’ make: *** [error.o] Error 1 Feedback We at least need to see line 31 of error.c and line 254 of mas.h, with preferably a few lines of context around each. This error may have nothing to do with how time_t is being declared. – John Bode Then I check in error.c (line no 31) -- #include "mas.h" then I check line no 254 in mas.h. in mas.h #include <sys/types.h> typedef struct _x{ time_t time; }x; Can anybody suggest where I am going wrong?

  • c++ function overloading, making fwrite/fread act like PHP versions

    - by Newbie
    I'm used to the PHP fwrite/fread parameter orders, and i want to make them the same in C++ too. I want it to work with char and string types, and also any data type i put in it (only if length is defined). I am total noob on c++, this is what i made so far: size_t fwrite(FILE *fp, const std::string buf, const size_t len = SIZE_MAX){ if(len == SIZE_MAX){ return fwrite(buf.c_str(), 1, buf.length(), fp); }else{ return fwrite(buf.c_str(), 1, len, fp); } } size_t fwrite(FILE *fp, const void *buf, const size_t len = SIZE_MAX){ if(len == SIZE_MAX){ return fwrite((const char *)buf, 1, strlen((const char *)buf), fp); }else{ return fwrite(buf, 1, len, fp); } } Should this work just fine? And how should this be done if i wanted to do it the absolutely best possible way?

  • How does Play recognize a particular websocket message?

    - by noncom
    I am looking at the websocket-chat example. It unveils much, but I still cannot get something. I understand how messages are received, processed and sent on the web page side. However, Play captures websocket messages by means of the receive method of an Akka actor. In the websocket-chat, there are several cases in this method, but I don't get, how does it know which websocket message should be mapped to which case. In fact, I don't understand the path that a websocket message follows upon entering Play's domain, how is it processed and how can different message types/kinds be sent from the webpage. I have not find any info or sources related to this. Could please someone explain this or point to some kind of a good reference? UPDATE: The link to the original example.

  • Database design: objects with different attributes

    - by Álvaro G. Vicario
    I'm designing a product database where products can have very different attributes depending on their type, but attributes are fixed for each type and types are not manageable at all. E.g.: magazine: title, issue_number, pages, copies, close_date, release_date web_site: name, bandwidth, hits, date_from, date_to I want to use InnoDB and enforce database integrity as much as the engine allows. What's the recommended way to handle this? I hate those designs where tables have 100 columns and most of the values are NULL so I thought about something like this: product_type ============ product_type_id INT product_type_name VARCHAR product ======= product_id INT product_name VARCHAR product_type_id INT -> Foreign key to product_type.product_type_id valid_since DATETIME valid_to DATETIME magazine ======== magazine_id INT title VARCHAR product_id INT -> Foreign key to product.product_id issue_number INT pages INT copies INT close_date DATETIME release_date DATETIME web_site ======== web_site_id INT name VARCHAR product_id INT -> Foreign key to product.product_id bandwidth INT hits INT date_from DATETIME date_to DATETIME This can handle cascaded product deletion but... Well, I'm not fully convinced...

  • Doing a SetLength on an array passed into a proc by reference

    - by csharpdefector
    Hi All, Sure, even I can do this... var testarray : array of string; setlength(testarray, 5); but if I want to get clever and have a procedure into which I pass the array by referance like this I cant do it! procedure DoStuffWithArray(var passedarray : array of string); begin setlength(passedarray, 5); end; compiler says 'incompatible types' on the single line of code in my proc. I can do other stuff on the array like set set element values if i do a setlength before i call the proc, but I cannot do the setlength in my proc, which is what I want to do. Any help much appreciated, thanks all.

  • jQuery autosuggest example

    - by RUtt
    I need to implement an "autosuggest" feature on our site but it needs to re-query the on every keystroke after a certain number of keys (like every character after 2 it would need to query again). So the result isn't a limiting search. For example, the autocomplete plugins I've seen work like the following: [looking for a county] 1. customer types 'CA' and the first result would return 'Canada', 'Cambodia', and 'Camaroon' 2. customer continues to type and hits 'M' the new results would query within the only the existing 3 results (producing results of just 'Cambodia' and 'Camaroon') I need a solution that would be the equivalent of querying my datasource on each keystroke. I already have the ajax call that will return my results based on the "typed" params. For example (in the above example), it would need to make an ajax call passing 'ca' first and if the customer kept typing passing 'can' on the 3 character and so forth. Thanks.

  • Are macro definitions compatible between MIPS and Intel C compiler?

    - by Derek
    I seem to be having a problem with a macro that I have defined in a C program. I compile this software and run it sucessfully with the MIPS compiler. It builds OK but throws the error "Segmentation fault" at runtime when using icc. I compiled both of these on 64 bit architectures (MIPS on SGI, with -64 flag and icc on an intel platform). Is there some magic switch I need to use to make this work correctly on both system? I turned on warnings for the intel compiler, and EVERY one of the places in my program where a macro is invoked throws a warning. Usually something along the lines of mismatched types on the macro's parameters (int to char *) or some such thing.

  • Decorators vs. classes in python web development.

    - by Tristan
    I've noticed three main ways Python web frameworks deal request handing: decorators, controller classes with methods for individual requests, and request classes with methods for GET/POST. I'm curious about the virtues of these three approaches. Are there major advantages or disadvantages to any of these approaches? To fix ideas, here are three examples. Bottle uses decorators: @route('/') def index(): return 'Hello World!' Pylons uses controller classes: class HelloController(BaseController): def index(self): return 'Hello World' Tornado uses request handler classes with methods for types: class MainHandler(tornado.web.RequestHandler): def get(self): self.write("Hello, world") Which style is the best practice?

  • Drupal: how to upgrade a running production website to a dev version?

    - by FractalizeR
    Can you help me to understand, how do I do Drupal website deployment and development? Suppose, I developed 1.0 version of Berty&Frank website. I copied everything to their production server and it is alive and kicking now. Site is already full of contents and is growing. I am asked to add additional features to the website. I am now experimenting with the way how I can implement them in a dev version. I am creating/deleting content types, fill created nodes with demo data just to see how they look like etc. Now I found the way and I want to upgrade production website to the same structure as my dev version now. How do I do that? Is the only way to manually make every change I made in dev version?

  • How do I use Declarations (type, inline, optimize) in Scheme?

    - by kunjaan
    How do I declare the types of the parameters in order to circumvent type checking? How do I optimize the speed to tell the compiler to run the function as fast as possible like (optimize speed (safety 0))? How do I make an inline function in Scheme? How do I use an unboxed representation of a data object? And finally are any of these important or necessary? Can I depend on my compiler to make these optimizations? thanks, kunjaan.

    - by daemonkid
    I have a c# component that will recieve a file of the following types .doc, .pdf, .xls, .rtf These will be sent by the calling siebel legacy app as a filestream. So... [LegacyApp] {Binary file stream} [Component] The legacy app is a black box that cant be modified to tell the component what file type (doc,pdf,xls) it is sending. The component needs to read this binary stream and create a file on the filesystem with the right extension. Any ideas? Thanks for your time.

  • Can I serialize a BitArray to XML?

    - by SimonNet
    Hello I have a business class which I need to serialize to xml. It has a BitArray property. I have decorated it with [XmlAttribute] but the serialization is failing with To be XML serializable, types which inherit from ICollection must have an implementation of Add(System.Boolean) at all levels of their inheritance hierarchy. System.Collections.BitArray does not implement Add(System.Boolean). I am not sure whether its possible to serialize to xml? If not what would be an efficient means of serializing the BitArray Thanks for looking

  • Does it make sense to study COBOL?

    - by Alon
    I have had a talk with a friend of mine about the relative vulnerability of different types of IT workers to unexpected unemployment (e.g. layoffs, company going out of business, obsolete skills etc.) as it seems COBOL developers (or maintainers?) seems very secure in their positions, regardless of the state if the economy or even how good they are. With so much critical COBOL code being around on the one side and the deminishing number of COBOL know-hows on the other , it actually makes sense to recommend someone starting their way in the IT world and looking for a relativity secure job to study and intern in COBOL! what do you think ?

  • mac, java 1.5: javax.mail not recognized as a jar file

    - by Helpme
    hello fellow java developers, Having a little issue with creating a java application on a macintosh computer (snow leopard). I've set up my application in eclipse, added all of the appropriate jar files, but for some reason the code is not recognizing some of my variables as valid types. I've imported the libraries via import javax.mail.*; import javax.mail.internet.*; These libraries are not recognized by the application. BUT I've put them on the build path! Any advice on how to fix this?

  • Design pattern: polymorphisim for list of objects

    - by ziang
    Suppose I have a class A, and A1, A2 inherits from A. There are 2 functions: List<A1> getListA1(){...} List<A2> getListA2(){...} Now I want to do something similar to both A1 and A2 in another function public void process(List<A>){...} If I want to pass the instance of either ListA1 or ListA2, of course the types doesn't match because the compiler doesn't allow the coercion from List< A1 to List< A. I can't do something like this: List<A1> listA1 = getListA1(); List<A> newList = (List<A>)listA1; //this is not allowed. So what is the best approach to the process()? Is there any way to do it in a universal way rather than write the similar code to both List and List?

  • Dijit Combobox filter autocomplete

    - by Apps
    I'm using dijit combobox for populating a JSON List. Also I'm using ItemFileReadStore for getting the JSON data from the server. Once the data is downloaded, when I click on the combobox it shows all the data. But I don't want the user to see all the data. The user should see the list only when he types something. I tried using queryExpr parameter-${0}*. But at that time the list is not populated.Can someone please help me to fix it? Any help will be greatly appreciated Thanks, Apps

  • Is there any way to use GUIDs in django?

    - by Jason Baker
    I have a couple of tables that are joined by GUIDs in SQL Server. Now, I've found a few custom fields to add support for GUIDs in django, but I tend to shy away from using code in blog posts if at all possible. I'm not going to do anything with the GUID other than join on it and maybe assign a GUID on new entries (although this is optional). Is there any way to allow this using django's built-in types? Like can I use some kind of char field or binary field and "trick" django into joining using it? If it's any help, I'm using django-pyodbc.

  • Are C++ Reads and Writes of an int atomic

    - by theschmitzer
    I have two threads, one updating an int and one reading it. This value is a statistic where the order of the read and write is irrelevant. My question is, do I need to synchronize access to this multi-byte value anyway? Or, put another way, can part of the write be complete and get interrupted, and then the read happen. For example, think of value = ox0000FFFF increment value to 0x00010000 Is there a time where the value looks like 0x0001FFFF that I should be worried about? Certainly the larger the type, the more possible something like this is I've always synchronized these types of accesses, but was curious what the community thought.

  • Where to put WPF specific code when using MVVM

    - by Surfbutler
    I'm just getting up to speed on MVVM, but all the examples I've seen so far are binding View controls to simple non-WPF specific data types such as strings and ints. However in our app I want to be able to set a button's border brush based on a number in the Model. At the moment, I translate the number into a brush in the ViewModel to keep the View XAML only, but is that right? I don't like putting WPF specific code in the ViewModel, but equally I don't like the idea of putting code-behind on my View panel. Which is the best way? Thanks

  • How to create a reusable form using COCOA bindings.

    - by Juliano Sott
    hi. I want to make a user interface in which the user can edit two objects at the same time. The main window would have a vertical split view and a form on each side of the view. The problem is that the two forms are identical and I don't want to duplicate the view components in the interface builder. I want to create the form one time and add a reference to it in each side of the split view, each one using a different object source. I could use a NSForm, but the form is not a simple grid of outputTexts and inputText. They have a master table, and diverse kinds of inputs types, like combos, in the detail. How do I create the reusable form using the interface builder? Or how can I do it programmatically? Do I have to create a subclass of NSView and add the individual components in the code? Thanks, Juliano

  • What structure of data use to communicate via tcp/ip in java?

    - by rmaster
    Let's assume I want to send many messages between 2 programs made in java that use TCP sockets. I think the most convienient way is to send objects like: PrintStream ps = new PrintStream(s.getOutputStream()); ObjectOutputStream oos = new ObjectOutputStream(ps); some_kind_of_object_here; oos.writeObject(some_kind_of_object_here); ps.print(oos); I want to send, strings, numbers, HashMaps, boolean values How can I do this using fx 1 object that can store all that properties? I though about ArrayList that is serializable and we can put there everything but is not elegant way. I want to send different types of data because user can choose from a variety of options that server can do for it. Any advices?

  • How to determine MIME Type set by htaccess in PHP

    - by Ed Marty
    I have a .htaccess file set up to define specific MIME types in directory root/a/b/, and all of the files are in the same directory. I have a php file that wants to serve those files, in directory root/c/, and needs to determine the content-type as defined by the .htaccess file. Is there any way to do this? PHP version is 5.1.6. mime_content_type returns text/plain, and I'd rather not try to parse the .htaccess file manually. I can move the file if necessary.
