  • Oracle/c#: How do i use bind variables with select statements to return multiple records?

    - by twiga
    I have a question regarding Oracle bind variables and select statements. What I would like to achieve is do a select on a number different values for the primary key. I would like to pass these values via an array using bind values. select * from tb_customers where cust_id = :1 int[] cust_id = { 11, 23, 31, 44 , 51 }; I then bind a DataReader to get the values into a table. The problem is that the resulting table only contains a single record (for cust_id=51). Thus it seems that each statement is executed independently (as it should), but I would like the results to be available as a collective (single table). A workaround is to create a temporary table, insert all the values of cust_id and then do a join against tb_customers. The problem with this approach is that I would require temporary tables for every different type of primary key, as I would like to use this against a number of tables (some even have combined primary keys). Is there anything I am missing?

  • Jquery javascript - How can I let users 'undo' their modifications?

    - by Bill Zimmerman
    Hi, i have a basic jquery app that allows a user to edit and manipulate some lists on a page. What I would like to do is have a button 'restore original list' that the user can press to undo his modifications. What is the best way to do this? I was thinking of just copying the DOM from the list down, and pasting it in a hidden element someplace else on the page. Is this the best way to do this? I also noticed that jquery has a .data() function which I could use if I converted the data to an array and stored it this way. What are the advantages and disadvantages? Also, I'm open to any suggestions people have if there is some method I haven't thought of. Thanks for your help!

  • Access violation using LocalAlloc()

    - by PaulH
    I have a Visual Studio 2008 Windows Mobile 6 C++ application that is using an API that requires the use of LocalAlloc(). To make my life easier, I created an implementation of a standard allocator that uses LocalAlloc() internally: /// Standard library allocator implementation using LocalAlloc and LocalReAlloc /// to create a dynamically-sized array. /// Memory allocated by this allocator is never deallocated. That is up to the /// user. template< class T, int max_allocations > class LocalAllocator { public: typedef T value_type; typedef size_t size_type; typedef ptrdiff_t difference_type; typedef T* pointer; typedef const T* const_pointer; typedef T& reference; typedef const T& const_reference; pointer address( reference r ) const { return &r; }; const_pointer address( const_reference r ) const { return &r; }; LocalAllocator() throw() : c_( NULL ) { }; /// Attempt to allocate a block of storage with enough space for n elements /// of type T. n>=1 && n<=max_allocations. /// If memory cannot be allocated, a std::bad_alloc() exception is thrown. pointer allocate( size_type n, const void* /*hint*/ = 0 ) { if( NULL == c_ ) { c_ = LocalAlloc( LPTR, sizeof( T ) * n ); } else { HLOCAL c = LocalReAlloc( c_, sizeof( T ) * n, LHND ); if( NULL == c ) LocalFree( c_ ); c_ = c; } if( NULL == c_ ) throw std::bad_alloc(); return reinterpret_cast< T* >( c_ ); }; /// Normally, this would release a block of previously allocated storage. /// Since that's not what we want, this function does nothing. void deallocate( pointer /*p*/, size_type /*n*/ ) { // no deallocation is performed. that is up to the user. }; /// maximum number of elements that can be allocated size_type max_size() const throw() { return max_allocations; }; private: /// current allocation point HLOCAL c_; }; // class LocalAllocator My application is using that allocator implementation in a std::vector< #define MAX_DIRECTORY_LISTING 512 std::vector< WIN32_FIND_DATA, LocalAllocator< WIN32_FIND_DATA, MAX_DIRECTORY_LISTING > > file_list; WIN32_FIND_DATA find_data = { 0 }; HANDLE find_file = ::FindFirstFile( folder.c_str(), &find_data ); if( NULL != find_file ) { do { // access violation here on the 257th item. file_list.push_back( find_data ); } while ( ::FindNextFile( find_file, &find_data ) ); ::FindClose( find_file ); } // data submitted to the API that requires LocalAlloc()'d array of WIN32_FIND_DATA structures SubmitData( &file_list.front() ); On the 257th item added to the vector<, the application crashes with an access violation: Data Abort: Thread=8e1b0400 Proc=8031c1b0 'rapiclnt' AKY=00008001 PC=03f9e3c8(coredll.dll+0x000543c8) RA=03f9ff04(coredll.dll+0x00055f04) BVA=21ae0020 FSR=00000007 First-chance exception at 0x03f9e3c8 in rapiclnt.exe: 0xC0000005: Access violation reading location 0x01ae0020.

  • Loading table sections when using headers

    - by Luis Tovar
    I cant seem to wrap my head around this. I have googled, and overstacked for hours now looking for examples that i can relate to. What I have is two arrays. The name of my first NSMutableArray is "showDates". I have 3 objects in here. Object 0: "Today, May 20th" Object 1: "Tomorrow, May 21st" Object 2: "Saturday, May 22nd" Then I have my second NSMutableArray named "showTimes" I have about 15 objects in there with strings in each object. ( i hope that makes sense? ) Each object is structured like this: Object 0: showID @"98022" eventID @"833" showTime @"1:30pm" showDate @"Today, May 20th" auditorium @"9" venue @"2991" Object 1: showID @"98222" eventID @"813" showTime @"2:30pm" showDate @"Tomorrow, May 21st" auditorium @"9" venue @"2991" Etc, etc, .... I have the headers working great in my tableView, but I cant seem to figure out how to add the objects in my "showTimes" array under the correct header. Any help would be greatly appreciated.

  • UISwitch quick toggle multiple times.

    - by Tejaswi Yerukalapudi
    I was playing around my app and I was toggling a UISwitch really fast (who can resist?). So, I toggled it really fast for 10-15 times, an array that should contain the data from the table view cell that I have my switch in either has extra copies of the same cell sometimes, just one copy (the correct case) a few times and no data in it at all some times. The app works fine if it's toggled at normal speed. I'm pretty sure this scenario won't really happen with my users, but I'm still curious as to why it's happening. Thanks, Teja

  • Laravel: validation for unique username issue

    - by T2theC
    I have a noodle scratcher that I can't seem to figure out. I am validating for unique usernames and emails addresses. I have the following rules: protected $rules = array( 'username' => 'required|min:4|unique:users,username', 'email' => 'email|unique:users,email', 'password' => 'min:6', ); If I update a form that has the username (which is the same as it currently is), I get a The username has already been taken. error. If I do the same with the email, I get no error at all. I know about adding the last param to the unique validation: 'unique:users,username,{{$id}}' or 'unique:users,username,'.$id This doesn't work on the username. I get the same issue. I can't figure out why this works for the email, but not the username. Anyone had a similar issue or know where I am going wrong? Many thanks,

  • how have defined connection within function for pdo communication with DB

    - by Scarface
    hey guys I just started trying to convert my query structure to PDO and I have come across a weird problem. When I call a pdo query connection within a function and the connection is included outside the function, the connection becomes undefined. Anyone know what I am doing wrong here? I was just playing with it, my example is below. include("includes/connection.php"); function query(){ $user='user'; $id='100'; $sql = 'SELECT * FROM users'; $stmt = $conn->prepare($sql); $result=$stmt->execute(array($user, $id)); echo $count=$stmt->rowCount(); if (!$result || $stmt->rowCount()>=1){ echo 'balls'; } // now iterate over the result as if we obtained // the $stmt in a call to PDO::query() while($r = $stmt->fetch(PDO::FETCH_ASSOC)) { echo "$r[username] $r[id] \n"; } } query();

  • Obtaining photo 'stars' rating using PHP

    - by DarwinIcesurfer
    I am trying to extract the photo 'stars' rating from .jpg files using php code. My intent is to show the highest rated images as part of a slideshow. I found that using the PHP_JPEG_Metadata_Toolkit_1.11 I am able to get the rating of the file if the rating is set from within Vista (Right click - Properties - Details - Set rating by clicking on stars) by reading the array returned by the Metadata_Toolkit $exif = get_EXIF_JPEG( $photodir . "/" . $filename ); $rating = $exif[0][18246]['Data'][0]; However if I set the rating using Adobe Bridge, I can see the 'stars' in Vista, but the $exif[0][18246]['Data'][0] returns a null value. Is PHP code available to read the ratings applied by both Windows Vista AND Adobe Bridge?

  • What is the best type to use for returning an image in my C# library project?

    - by Sergio Tapia
    I'm making a project that will scrap information about a movie and return all sorts of goodies. This will be a .dll that other developers will use in their projects. For example, if they want to set a pictureBox image to the movies poster, what would be the best way to handle my library returning the image? //Set the image to The Matrix poster. pictureBox1.Image = MyLibrary.GetPoster("The Matrix"); Should I return an Image? A Byte[] array?

  • JQuery Selector - Select this, not that?

    - by JasonS
    Hi, I have created a script which is surprisingly working. (I do not do much JavaScript) What I have is a load of images listed within a div. These images are hidden. JQuery gets the properties of the images and puts them into an array. When the body is clicked, the background image of the page changes. This works nicely. However, I now have a problem. There are several elements which I shouldn't change the background when they are clicked. Namely, navigation, footer and caption. How do I create a selector which makes the body clickable, yet ignores clicks on the above 3 div's?

  • what is wrong: "value Parsers is not a member of package scala.util.parsing.combinator"?

    - by Nick Fortescue
    I've got the above odd error message that I don't understand "value Parsers is not a member of package scala.util.parsing.combinator". I'm trying to learn Parser combinators by writing a C parser step by step. I started at token, so I have the classes: import util.parsing.combinator.JavaTokenParsers object CeeParser extends JavaTokenParsers { def token: Parser[CeeExpr] = ident } abstract class CeeExpr case class Token(name: String) extends CeeExpr This is as simple as I could make it. The code below works fine, but if I uncomment the commented line I get the error message given above: object Play { def main(args: Array[String]) { //val parser: _root_.scala.util.parsing.combinator.Parsers.Parser[CeeExpr] CeeParser.token val x = CeeParser.token print(x) } } In case it is a problem with my setup, I'm using scala 2.7.6 via the scala-plugin for intellij. Can anyone shed any light on this? The message is wrong, Parsers is a member of scala.util.parsing.combinator.

  • url to http request object

    - by takeshin
    I need to convert string like this: $url = 'module/controller/action/param1/param1value/paramX/paramXvalue'; to url regarding current router (including translation and so on). Usually I generate the target urls using url view helper, but for this I need to specify all params, so I would need to manually explode the string. I tried to use request object, like this: $request = new Zend_Controller_Request_Http(); // some code here passing the $url Zend_Debug::dump($request->getControllerName()); // null instead of 'controllers' Zend_Debug::dump($request->getParams()); // null instead of array but this seems to be suspected. Do I need to dispatch this request? How to handle this case well?

  • iPhone: Error and error handling confusion in comparison.

    NSArray *results = [managedObjectContext executeFetchRequest:request error:&error]; if(results == nil){ NSLog(@"No results found"); searchObj = nil; }else{ if ([[[results objectAtIndex:0] name] caseInsensitiveCompare:passdTextToSearchFor] == 0) { NSLog(@"results %@", [[results objectAtIndex:0] name]); searchObj = [results objectAtIndex:0]; }else { NSLog(@"No results found"); searchObj = nil; } } The code above compares data a user enters to data pulled from a database. If I enter data which is in the database; it works. But if I enter complete gibberish it returns the error below instead of "No results found." *** WebKit discarded an uncaught exception in the webView:shouldInsertText:replacingDOMRange:givenAction: delegate: <NSRangeException> *** -[NSCFArray objectAtIndex:]: index (0) beyond bounds (0) The results array being null should be accounted for during the checks in the above code, no?

  • See if item exists once in Enumerable (Linq)

    - by Stacey
    Given a list... class Item { public Name { get; set; } } List<Item> items = new List<Item> { new Item() { Name = "Item 1" }, new Item() { Name = "Item 1" }, new Item() { Name = "Item 2" }, new Item() { Name = "Item 3" } } List<Item> listing = new List<Item> { new Item() { Name = "Item 1" }, new Item() { Name = "Item 2" }, new Item() { Name = "Item 3" } new Item() { Name = "Item 4" } } etc. I need to create a third array that will cancel out double instances between the two; however items with "Name 1" are both the same, but different 'instances'. So the third List should have 1 instance of Item 1, since 'items' had 2 instances. Any ideas of how this can be done through Linq?
