  • Move and rename file in android

    - by Andre Fróes
    I am trying to copy a file to another folder in the android, but so far, i got no success. I manage to do so with a selected image and when taking a photo, but not with files. I've read and tried several solutions passed by the community (searched over the forum and the internet), but none of it was able to solve my problem when copying. First things first. I added the permissions to my manifest: <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /> after that, before copying a file, i print its filepath and the directory file path: 06-10 11:11:11.700: I/System.out(1442): /mimetype/storage/sdcard/Misc/Javascript erros for Submit and Plan buttons in IE.doc 06-10 11:11:11.710: I/System.out(1442): /storage/sdcard/mywfm/checklist-files both exists: to copy the file to the expected folder I used the FileUtils: try { FileUtils.copyFile(selectedFile, dir); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } The problem is: I get no exception and the file isn't there. I tried this solution either: How to move/rename file from internal app storage to external storage on Android? same thing, no exception, but no file either.

    I want to move the character left, right up, and down in applet, but it is not moving at all. here is my code, help please import javax.swing.JPanel; import java.awt.image.BufferedImage; import java.io.*; import javax.imageio.ImageIO; import java.applet.*; import java.awt.event.*; import java.awt.*; public class drawCenter extends Applet { private int x,y;// the x and y of the position of the player private BufferedImage image, pos; public void init( ) { try { image = ImageIO.read(new File("pokemonCenter.png")); pos = ImageIO.read(new File("player/maleInGame.png")); } catch (IOException ex) { } x = 150; y = 171; } public void keyPressed(KeyEvent e) { int keyCode = e.getKeyCode(); switch( keyCode ) { case KeyEvent.VK_UP: if( y>0 ) { y=y-19; repaint(); } break; case KeyEvent.VK_DOWN: if( y<171 ) { y=y+19; repaint(); } break; case KeyEvent.VK_LEFT:if( x>0 ) { x=x-15; repaint(); } break; case KeyEvent.VK_RIGHT:if( x<285 ) { x=x+15; repaint(); } break; } e.consume(); } public void keyReleased(){ } public void paint( Graphics g ) { g.drawImage(image, 0, 0, null); g.drawImage(pos, x, y, null); } }

  • C++ How to deep copy a struct with unknown datatype?

    - by Ewald Peters
    hi, i have a "data provider" which stores its output in a struct of a certain type, for instance struct DATA_TYPE1{ std::string data_string; }; then this struct has to be casted into a general datatype, i thought about void * or char *, because the "intermediate" object that copies and stores it in its binary tree should be able to store many different types of such struct data. struct BINARY_TREE_ENTRY{ void * DATA; struct BINARY_TREE_ENTRY * next; }; this void * is then later taken by another object that casts the void * back into the (struct DATA_TYPE1 *) to get the original data. so the sender and the receiver know about the datatype DATA_TYPE1 but not the copying object inbetween. but how can the intermidiate object deep copy the contents of the different structs, when it doesn't know the datatype, only void * and it has no method to copy the real contents; dynamic_cast doesn't work for void *; the "intermediate" object should do something like: void store_data(void * CASTED_DATA_STRUCT){ void * DATA_COPY = create_a_deepcopy_of(CASTED_DATA_STRUCT); push_into_bintree(DATA_COPY); } a simple solution would be that the sending object doesn't delete the sent data struct, til the receiving object got it, but the sending objects are dynamically created and deleted, before the receiver got the data from the intermediate object, for asynchronous communication, therefore i want to copy it. instead of converting it to void * i also tried converting to a superclass pointer of which the intermediate copying object knows about, and which is inherited by all the different datatypes of the structs: struct DATA_BASE_OBJECT{ public: DATA_BASE_OBJECT(){} DATA_BASE_OBJECT(DATA_BASE_OBJECT * old_ptr){ std::cout << "this should be automatically overridden!" << std::endl; } virtual ~DATA_BASE_OBJECT(){} }; struct DATA_TYPE1 : public DATA_BASE_OBJECT { public: string str; DATA_TYPE1(){} ~DATA_TYPE1(){} DATA_TYPE1(DATA_TYPE1 * old_ptr){ str = old_ptr->str; } }; and the corresponding binary tree entry would then be: struct BINARY_TREE_ENTRY{ struct DATA_BASE_OBJECT * DATA; struct BINARY_TREE_ENTRY * next; }; and to then copy the unknown datatype, i tried in the class that just gets the unknown datatype as a struct DATA_BASE_OBJECT * (before it was the void *): void * copy_data(DATA_BASE_OBJECT * data_that_i_get_in_the_sub_struct){ struct DATA_BASE_OBJECT * copy_sub = new DATA_BASE_OBJECT(data_that_i_get_in_the_sub_struct); push_into_bintree(copy_sub); } i then added a copy constructor to the DATA_BASE_OBJECT, but if the struct DATA_TYPE1 is first casted to a DATA_BASE_OBJECT and then copied, the included sub object DATA_TYPE1 is not also copied. i then thought what about finding out the size of the actual object to copy and then just memcopy it, but the bytes are not stored in one row and how do i find out the real size in memory of the struct DATA_TYPE1 which holds a std::string? Which other c++ methods are available to deepcopy an unknown datatype (and to maybe get the datatype information somehow else during runtime) thanks Ewald

  • How to approach copying objects with smart pointers as class attributes?

    - by tomislav-maric
    From the boost library documentation I read this: Conceptually, smart pointers are seen as owning the object pointed to, and thus responsible for deletion of the object when it is no longer needed. I have a very simple problem: I want to use RAII for pointer attributes of a class that is Copyable and Assignable. The copy and assignment operations should be deep: every object should have its own copy of the actual data. Also, RTTI needs to be available for the attributes (their type may also be determined at runtime). Should I be searching for an implementation of a Copyable smart pointer (the data are small, so I don't need Copy on Write pointers), or do I delegate the copy operation to the copy constructors of my objects as shown in this answer? Which smart pointer do I choose for simple RAII of a class that is copyable and assignable? (I'm thinking that the unique_ptr with delegated copy/assignment operations to the class copy constructor and assignment operator would make a proper choice, but I am not sure) Here's a pseudocode for the problem using raw pointers, it's just a problem description, not a running C++ code: // Operation interface class ModelOperation { public: virtual void operate = (); }; // Implementation of an operation called Special class SpecialModelOperation : public ModelOperation { private: // Private attributes are present here in a real implementation. public: // Implement operation void operate () {}; }; // All operations conform to ModelOperation interface // These are possible operation names: // class MoreSpecialOperation; // class DifferentOperation; // Concrete model with different operations class MyModel { private: ModelOperation* firstOperation_; ModelOperation* secondOperation_; public: MyModel() : firstOperation_(0), secondOperation_(0) { // Forgetting about run-time type definition from input files here. firstOperation_ = new MoreSpecialOperation(); secondOperation_ = new DifferentOperation(); } void operate() { firstOperation_->operate(); secondOperation_->operate(); } ~MyModel() { delete firstOperation_; firstOperation_ = 0; delete secondOperation_; secondOperation_ = 0; } }; int main() { MyModel modelOne; // Some internal scope { // I want modelTwo to have its own set of copied, not referenced // operations, and at the same time I need RAII to work for it, // as soon as it goes out of scope. MyModel modelTwo (modelOne); } return 0; }

  • Move options between multiple dropdown lists

    - by Martha
    We currently have a form with the standard multi-select functionality of "here are the available options, here are the selected options, here are some buttons to move stuff back and forth." However, the client now wants the ability to not just select certain items, but to also categorize them. For example, given a list of books, they want to not just select the ones they own, but also the ones they've read, the ones they would like to read, and the ones they've heard about. (All examples fictional.) Thankfully, a selected item can only be in one category at a time. I can find many examples of moving items between listboxes, but not a single one for moving items between multiple listboxes. To add to the complication, the form needs to have two sets of list+categories, e.g. a list of movies that need to be categorized in addition to the aforementioned books. An additional problem is that sorting between lists is all well and good in the javascript-enabled world, but I can't really think of a good fallback interface for, say, mobile browsers. Maybe a pseudo-listbox with radio buttons next to each item? The master list of items will in general be very long - over 100 items, certainly, possibly many more. Any given category will most likely contain one or two selected items, but the possibility exists for a category to have dozens of selected items, or zero selected items. As far as OS and stuff, the site is in classic asp (quit snickering!), the server-side code is VBScript, and so far we've avoided the various Javascript libraries by the simple expedient of almost never using client-side scripting. This one form for this one client is currently the big exception. Give 'em an inch and they want a mile... Oh, and I have to add: I suck at Javascript, or really at any C-descendant language. Curly braces give me hives. I'd really, really like something I can just copy & paste into my page, maybe tweak some variable names, and never look at it again. A girl can dream, can't she? :)

To add to the complication, the form needs to have two sets of list+categories, e.g. a list of movies that need to be categorized in addition to the aforementioned books. EDIT: Having now actually sat down to try to code the non-javascripty bits, I need to revise my question, because I realized that multiple select lists won't really work from the "how do I inform the server about all this lovely new information" standpoint. So the html code is now a pseudo-listbox, i.e. an unordered list (ul) displayed in a box with a scrollbar, and each list item (<li>) has a set of five radio buttons (unselected/own/read/like/heard). My task is still roughly the same: how to take this one list and make it easy to categorize the items, in such a way that the user can tell at a glance what is in what category. (The pseudo-listbox has some of the same disadvantages as a multi-select listbox, namely it's hard to tell what's selected if the list is long enough to scroll.) The dream solution would be a drag-and-drop type thing, but at this point even buttons would be OK. Another modification (a good one) is that the client has revised the lists, so the longest is now "only" 62 items long (instead of the many hundreds they had before). The categories will still mostly contain zero, one, or two selected items, possibly a couple more if the user was overzealous. As far as OS and stuff, the site is in classic asp (quit snickering!), the server-side code is VBScript, and so far we've avoided the various Javascript libraries by the simple expedient of almost never using client-side scripting.

  • Editing Neo Slider to move in one direction

    - by user2106416
    I have a website with brandspace theme from pixelentity. Currently, the slider move from right to left ( auto transition) . But, when the slider reaches the last image, it will go back to the first image by making all previous images sliding back from left to right. I want to make the slider to have a normal transition,i.e. going back to first image but still with the image sliding from right to left. Below is the slider.php code.: <?php $t =& peTheme(); ?> <?php list($pid,$conf,$loop) = $t->template->data(); ?> <?php $w = $t->media->width(940); ?> <?php $h = $t->media->height(300); ?> <div class="peSlider peVolo" data-autopause="disabled" data-plugin="<?php echo apply_filters("pe_theme_slider_plugin","peVolo"); ?>" data-controls-arrows="edges-full" data-controls-bullets="disabled" data-icon-font="enabled"> <?php while ($slide =& $loop->next()): ?> <?php $link = empty($slide->link) ? false: $slide->link; ?> <?php $img = $t->image->resizedImg($slide->img,$w,$h); ?> <div data-delay="4" <?php echo $slide->idx == 0 ? ' class="visible"' : ''; ?>> <?php if (isset($slide->caption)) $t->slider->caption($slide->caption); ?> <?php if ($link): ?> <a href="<?php echo $link ?>" data-flare-gallery="fsGallery<?php echo $pid ?>"> <?php echo $img; ?> </a> <?php else: ?> <?php echo $img; ?> <?php endif; ?> </div> <?php endwhile; ?> </div>

  • Refactor the following two C++ methods to move out duplicate code

    - by ossandcad
    I have the following two methods that (as you can see) are similar in most of its statements except for one (see below for details) unsigned int CSWX::getLineParameters(const SURFACE & surface, vector<double> & params) { VARIANT varParams; surface->getPlaneParams(varParams); // this is the line of code that is different SafeDoubleArray sdParams(varParams); for( int i = 0 ; i < sdParams.getSize() ; ++i ) { params.push_back(sdParams[i]); } if( params.size() > 0 ) return 0; return 1; } unsigned int CSWX::getPlaneParameters(const CURVE & curve, vector<double> & params) { VARIANT varParams; curve->get_LineParams(varParams); // this is the line of code that is different SafeDoubleArray sdParams(varParams); for( int i = 0 ; i < sdParams.getSize() ; ++i ) { params.push_back(sdParams[i]); } if( params.size() > 0 ) return 0; return 1; } Is there any technique that I can use to move the common lines of code of the two methods out to a separate method, that could be called from the two variations - OR - possibly combine the two methods to a single method? The following are the restrictions: The classes SURFACE and CURVE are from 3rd party libraries and hence unmodifiable. (If it helps they are both derived from IDispatch) There are even more similar classes (e.g. FACE) that could fit into this "template" (not C++ template, just the flow of lines of code) I know the following could (possibly?) be implemented as solutions but am really hoping there is a better solution: I could add a 3rd parameter to the 2 methods - e.g. an enum - that identifies the 1st parameter (e.g. enum::input_type_surface, enum::input_type_curve) I could pass in an IDispatch and try dynamic_cast< and test which cast is NON_NULL and do an if-else to call the right method (e.g. getPlaneParams() vs. get_LineParams()) The following is not a restriction but would be a requirement because of my teammates resistance: Not implement a new class that inherits from SURFACE/CURVE etc. (They would much prefer to solve it using the enum solution I stated above)

  • Move already (i.e. not new) completed files in rtorrent

    - by Skippy le Grand Gourou
    I've been using rtorrent for a while with a single directory. Now I figured out it was possible to use different directories and even to move completed downloads elsewhere, so according to the rtorrent wiki I edited my .rtorrent.rc as follow : # Download directory directory = /Medias/torrents/ # Watching directories schedule = watch_directory_1,5,60,"load_start=/path/to/dl/dir1/*.torrent,d.set_custom1=/path/to/done/dir1" schedule = watch_directory_2,5,60,"load_start=/path/to/dl/dir2/*.torrent,d.set_custom1=/path/to/done/dir2" # On completion, move the torrent to the directory from custom1. system.method.set_key = event.download.finished,move_complete,"d.set_directory=$d.get_custom1= ;execute=mv,-u,$d.get_base_path=,$d.get_custom1=" It seems to work for new torrents. However I have a bunch of completed files I have already downloaded before to split directories, and for them it does not work : if I delete their file in the session directory, rtorrent will check the hash but won't move them, and if I move them by myself rtorrent won't see them and will try to redownload them. So how can I tell rtorrent either to move them or that they are in another directory ? Thanks.

  • How does Unity.Resolve know which constructor to use?

    - by stiank81
    Given a class with several constructors - how can I tell Resolve which constructor to use? Consider the following example class: public class Foo { public Foo() { } public Foo(IBar bar) { Bar = bar; } public Foo(string name, IBar bar) { Bar = bar; Name = name; } public IBar Bar { get; set; } public string Name { get; set; } } If I want to create an object of type Foo using Resolve how will Resolve know which constructor to use? And how can I tell it to use the right one? Let's say I have a container with an IBar registered - will it understand that it should favor the constructor taking IBar? And if I specify a string too - will it use the (string, IBar) constructor? Foo foo = unityContainer.Resolve<Foo>(); And please ignore the fact that it would probably be easier if the class just had a single constructor...

    - by asker
    I'm am fairly new to Ubuntu and am finding it absolutely wonderful except for one thing, which is the inability to move the launcher. I am used to using windows, and though I hated it, I would like the ability to move the launcher to the bottom, both because I find it more convenient and familiar. I've surfed around and found some methods for Ubuntu 11.10, but nothing for 12.04, so any help would be appreciated. Thank you all for your help!

  • way to do if(x > x2) x = x2 with rotation?

    - by CyanPrime
    Alright, so I got this walking code, and some collision detection, now the collision detection returns a Vector3f of the closest point on the triangle that the projected position is at (pos + move), so then I project my position again in the walking method/function and if the projected position's x is the nearest point'x the projected position's x becomes the nearist point's x. same with their z points, but if I'm moving in a different direction from 0 degrees XZ how would I rotate the equation/condition? Here is what I got so far, and it's not working, as I go through walls, and such. Vector3f move = new Vector3f(0,0,0); move.x = (float)-Math.cos(Math.toRadians(yaw)); move.z = (float)-Math.sin(Math.toRadians(yaw)); // System.out.println("slopeNormal.z: " + slopeNormal.z + "move.z: " + move.z); move.normalise(); move.scale(movementSpeed * delta); float horizontaldotproduct = move.x * slopeNormal.x + move.z * slopeNormal.z; move.y = -horizontaldotproduct * slopeNormal.y; Vector3f dest = colCheck(pos, move, model, drawDist, movementSpeed, delta); Vector3f projPos = new Vector3f(pos); Vector3f.add(projPos, move, projPos); if(projPos.x > 0 && dest.x > 0 && projPos.x < dest.x) projPos.x = dest.x; else if(projPos.x < 0 && dest.x < 0 && projPos.x > dest.x) projPos.x = dest.x; if(projPos.z > 0 && dest.z > 0 && projPos.z < dest.z) projPos.z = dest.z; else if(projPos.z < 0 && dest.z < 0 && projPos.z > dest.z) projPos.z = dest.z; pos = new Vector3f(projPos);

  • What class to use in order to have a number move around the screen?

    - by AllenZ41
    What i am trying to accomplish is have a randomly created number move around the screen but it is touchable. I am planning to have lots of numbers on the screen, so my question is what class is appropriate to use, so I could set a number randomly at run time and display it while it moves around the screen? I was planning the use a TextView, since I want to use a custom font of mine but I think creating a bunch at a time could cause a memory problem and to my understanding they cant move around the screen at runtime.

  • Can I move the unity launcher in 12.10? [closed]

    - by Linds
    Possible Duplicate: Can I move the Unity launcher? I've just recently downloaded ubuntu 12.10, and just like everyone else using the Unity Launcher I would like to move it to the bottom of the screen. I know there are patches for 11.10, and I think for 12.04, but I haven't been able to find anything to solve this problem on 12.10. Is there a way, or is everyone else with 12.10 waiting for a solution as well?

  • Is there ever a reason to do all an object's work in a constructor?

    - by Kane
    Let me preface this by saying this is not my code nor my coworkers' code. Years ago when our company was smaller, we had some projects we needed done that we did not have the capacity for, so they were outsourced. Now, I have nothing against outsourcing or contractors in general, but the codebase they produced is a mass of WTFs. That being said, it does (mostly) work, so I suppose it's in the top 10% of outsourced projects I've seen. As our company has grown, we've tried to take more of our development in house. This particular project landed in my lap so I've been going over it, cleaning it up, adding tests, etc etc. There's one pattern I see repeated a lot and it seems so mindblowingly awful that I wondered if maybe there is a reason and I just don't see it. The pattern is an object with no public methods or members, just a public constructor that does all the work of the object. For example, (the code is in Java, if that matters, but I hope this to be a more general question): public class Foo { private int bar; private String baz; public Foo(File f) { execute(f); } private void execute(File f) { // FTP the file to some hardcoded location, // or parse the file and commit to the database, or whatever } } If you're wondering, this type of code is often called in the following manner: for(File f : someListOfFiles) { new Foo(f); } Now, I was taught long ago that instantiated objects in a loop is generally a bad idea, and that constructors should do a minimum of work. Looking at this code it looks like it would be better to drop the constructor and make execute a public static method. I did ask the contractor why it was done this way, and the response I got was "We can change it if you want". Which was not really helpful. Anyway, is there ever a reason to do something like this, in any programming language, or is this just another submission to the Daily WTF?

  • What's the proper term for a function inverse to a constructor? Deconstructor, destructor, or something else?

    - by Petr Pudlák
    Edit: I'm rephrasing the question a bit. Apparently I caused some confusion because I didn't realize that the term destructor is used in OOP for something quite different - it's a function invoked when an object is being destroyed. In functional programming we (try to) avoid mutable state so there is no such equivalent to it. (I added the proper tag to the question.) Instead, I've seen that the record field for unwrapping a value (especially for single-valued data types such as newtypes) is sometimes called destructor or perhaps deconstructor. For example, let's have (in Haskell): newtype Wrap = Wrap { unwrap :: Int } Here Wrap is the constructor and unwrap is what? I've seen both, for example: ... Most often, one supplies smart constructors and destructors for these to ease working with them. ... at Haskell wiki, or ... The general theme here is to fuse constructor - deconstructor pairs like ... at Haskell wikibook (here it's probably meant in a bit more general sense). The questions are: How do we call unwrap in functional programming? Deconstructor? Destructor? Or by some other term? And to clarify, is this terminology applicable to other functional languages, or is it used just in the Has

  • Are injectable classes allowed to have constructor parameters in DI?

    - by Songo
    Given the following code: class ClientClass{ public function print(){ //some code to calculate $inputString $parser= new Parser($inputString); $result= $parser->parse(); } } class Parser{ private $inputString; public __construct($inputString){ $this->inputString=$inputString; } public function parse(){ //some code } } Now the ClientClass has dependency on class Parser. However, if I wanted to use Dependency Injection for unit testing it would cause a problem because now I can't send the input string to the parser constructor like before as its calculated inside ClientCalss itself: class ClientClass{ private $parser; public __construct(Parser $parser){ $this->parser=$parser; } public function print(){ //some code to calculate $inputString $result= $this->parser->parse(); //--> will throw an exception since no string was provided } } The only solution I found was to modify all my classes that took parameters in their constructors to utilize Setters instead (example: setInputString()). However, I think there might be a better solution than this because sometimes modifying existing classes can cause much harm than benefit. So, Are injectable classes not allowed to have input parameters? If a class must take input parameters in its constructor, what would be the way to inject it properly? UPDATE Just for clarification, the problem happens when in my production code I decide to do this: $clientClass= new ClientClass(new Parser($inputString));//--->I have no way to predict $inputString as it is calculated inside `ClientClass` itself. UPDATE 2 Again for clarification, I'm trying to find a general solution to the problem not for this example code only because some of my classes have 2, 3 or 4 parameters in their constructors not only one.

  • MVVM load data during or after ViewModel construction?

    - by mkmurray
    My generic question is as the title states, is it best to load data during ViewModel construction or afterward through some Loaded event handling? I'm guessing the answer is after construction via some Loaded event handling, but I'm wondering how that is most cleanly coordinated between ViewModel and View? Here's more details about my situation and the particular problem I'm trying to solve: I am using the MVVM Light framework as well as Unity for DI. I have some nested Views, each bound to a corresponding ViewModel. The ViewModels are bound to each View's root control DataContext via the ViewModelLocator idea that Laurent Bugnion has put into MVVM Light. This allows for finding ViewModels via a static resource and for controlling the lifetime of ViewModels via a Dependency Injection framework, in this case Unity. It also allows for Expression Blend to see everything in regard to ViewModels and how to bind them. So anyway, I've got a parent View that has a ComboBox databound to an ObservableCollection in its ViewModel. The ComboBox's SelectedItem is also bound (two-way) to a property on the ViewModel. When the selection of the ComboBox changes, this is to trigger updates in other views and subviews. Currently I am accomplishing this via the Messaging system that is found in MVVM Light. This is all working great and as expected when you choose different items in the ComboBox. However, the ViewModel is getting its data during construction time via a series of initializing method calls. This seems to only be a problem if I want to control what the initial SelectedItem of the ComboBox is. Using MVVM Light's messaging system, I currently have it set up where the setter of the ViewModel's SelectedItem property is the one broadcasting the update and the other interested ViewModels register for the message in their constructors. It appears I am currently trying to set the SelectedItem via the ViewModel at construction time, which hasn't allowed sub-ViewModels to be constructed and register yet. What would be the cleanest way to coordinate the data load and initial setting of SelectedItem within the ViewModel? I really want to stick with putting as little in the View's code-behind as is reasonable. I think I just need a way for the ViewModel to know when stuff has Loaded and that it can then continue to load the data and finalize the setup phase. Thanks in advance for your responses.

  • iPhone keyboard's return key will move curser to next textfield

    - by iAm
    Hello Fellow Koder ••• I have a TableViewController that is using a grouped Style and has two(2) sections. The first section has 4 rows and the second section has 3 rows. I have placed a UILabel and a UITextField in each cell, and have a custom method(textFieldDone:) to handle the cursor movement to the next text field when the return key is press. This works fine and dandy if there is only one section, but I have two :( and yes I need two:) so I started koden' up an answer, but got results that just don't work, I did notice during my debugging that cell Identifier (I use Two) is only showing the one (in the debug consol) and it's the first one only (Generic Cell). - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { UITableViewCell *cell = nil; switch (indexPath.section) { case AUTO_DETAILS: { static NSString *cellID = @"GenericCell"; cell = [tableView dequeueReusableCellWithIdentifier:cellID]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue2 reuseIdentifier:cellID] autorelease]; UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(10, 10, 75, 25)]; label.tag = kLabelTag; label.font = [UIFont boldSystemFontOfSize:14]; label.textAlignment = UITextAlignmentRight; [cell.contentView addSubview:label]; [label release]; UITextField *textField = [[UITextField alloc] initWithFrame:CGRectMake(90, 12, 200, 25)]; textField.clearsOnBeginEditing = NO; [textField setDelegate:self]; [textField addTarget:self action:@selector(topTextFieldDone:) forControlEvents:UIControlEventEditingDidEndOnExit]; [cell.contentView addSubview:textField]; } NSInteger row = [indexPath row]; UILabel *label = (UILabel *)[cell viewWithTag:kLabelTag]; UITextField *textField = nil; for (UIView *oneView in cell.contentView.subviews) { if ([oneView isMemberOfClass:[UITextField class]]) textField = (UITextField *)oneView; } label.text = [topCellLabels objectAtIndex:row]; NSNumber *rowAsNum = [[NSNumber alloc] initWithInt:row]; switch (row) { case kMakeRowIndex: if ([[tempValues allKeys] containsObject:rowAsNum]) textField.text = [tempValues objectForKey:rowAsNum]; else textField.text = automobile.make; break; case kModelRowIndex: if ([[tempValues allKeys] containsObject:rowAsNum]) textField.text = [tempValues objectForKey:rowAsNum]; else textField.text = automobile.model; break; case kYearRowIndex: if ([[tempValues allKeys] containsObject:rowAsNum]) textField.text = [tempValues objectForKey:rowAsNum]; else textField.text = automobile.year; break; case kNotesRowIndex: if ([[tempValues allKeys] containsObject:rowAsNum]) textField.text = [tempValues objectForKey:rowAsNum]; else textField.text = automobile.notes; break; default: break; } if (textFieldBeingEdited == textField) { textFieldBeingEdited = nil; } textField.tag = row; [rowAsNum release]; break; } case AUTO_REGISTRATION: { static NSString *AutoEditCellID = @"AutoEditCellID"; cell = [tableView dequeueReusableCellWithIdentifier:AutoEditCellID]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue2 reuseIdentifier:AutoEditCellID] autorelease]; UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(10, 10, 75, 25)]; label.tag = kLabelTag; label.font = [UIFont boldSystemFontOfSize:14]; label.textAlignment = UITextAlignmentRight; [cell.contentView addSubview:label]; [label release]; UITextField *textField = [[UITextField alloc] initWithFrame:CGRectMake(90, 12, 200, 25)]; textField.clearsOnBeginEditing = NO; [textField setDelegate:self]; [textField addTarget:self action:@selector(bottomTextFieldDone:) forControlEvents:UIControlEventEditingDidEndOnExit]; [cell.contentView addSubview:textField]; } NSInteger row = [indexPath row]; UILabel *label = (UILabel *)[cell viewWithTag:kLabelTag]; UITextField *textField = nil; for (UIView *oneView in cell.contentView.subviews) { if ([oneView isMemberOfClass:[UITextField class]]) textField = (UITextField *)oneView; } label.text = [bottomCellLabels objectAtIndex:row]; NSNumber *rowAsNum = [[NSNumber alloc] initWithInt:row]; switch (row) { case 0: if ([[tempValues allKeys] containsObject:rowAsNum]) textField.text = [tempValues objectForKey:rowAsNum]; else textField.text = automobile.vinNumber; break; case 1: if ([[tempValues allKeys] containsObject:rowAsNum]) textField.text = [tempValues objectForKey:rowAsNum]; else textField.text = automobile.policyNumber; break; case 2: if ([[tempValues allKeys] containsObject:rowAsNum]) textField.text = [tempValues objectForKey:rowAsNum]; else textField.text = automobile.licensePlate; break; default: break; } if (textFieldBeingEdited == textField) { textFieldBeingEdited = nil; } textField.tag = row; [rowAsNum release]; break; } default: break; } return cell; } Now remember that the first section is working fine and the kode for that method is this: -(IBAction)topTextFieldDone:(id)sender { UITableViewCell *cell = (UITableViewCell *)[[sender superview] superview]; UITableView *table = (UITableView *)[cell superview]; NSIndexPath *textFieldIndexPath = [table indexPathForCell:cell]; NSUInteger row = [textFieldIndexPath row]; row++; if (row > kNumOfEditableRows) row = 0; NSUInteger newIndex[] = {0, row}; NSIndexPath *newPath = [[NSIndexPath alloc] initWithIndexes:newIndex length:2]; UITableViewCell *nextCell = [self.tableView cellForRowAtIndexPath:newPath]; UITextField *nextField = nil; for (UIView *oneView in nextCell.contentView.subviews) { if ([oneView isMemberOfClass:[UITextField class]]) nextField = (UITextField *)oneView; } [nextField becomeFirstResponder]; } It was my idea to just create a second method (secondSectionTextFieldDone:) like this -(IBAction)bottomTextFieldDone:(id)sender { UITableViewCell *cell = (UITableViewCell *)[[sender superview] superview]; UITableView *table = (UITableView *)[cell superview]; NSIndexPath *textFieldIndexPath = [table indexPathForCell:cell]; NSUInteger row = [textFieldIndexPath row]; row++; if (row > 3) row = 0; NSUInteger newIndex[] = {0, row}; NSIndexPath *newPath = [[NSIndexPath alloc] initWithIndexes:newIndex length:2]; UITableViewCell *nextCell = [self.tableView cellForRowAtIndexPath:newPath]; UITextField *nextField = nil; NSString *string = [NSString stringWithFormat:@"AutoEditCellID"]; for (UIView *oneView in nextCell.contentView.subviews) { NSLog(@"%@", nextCell.reuseIdentifier); /* DEBUG LOG */ if ([oneView isMemberOfClass:[UITextField class]] && (nextCell.reuseIdentifier == string)) nextField = (UITextField *)oneView; } [nextField becomeFirstResponder]; } but the result does not solve the issue. so my question is, how can i get the cursor to jump to the next textfield in the section that it is in, If there is one, and if not, then send a message "resignFirstResponder" so that, the keyboard goes away.

  • How to move an element in Diagonal Movement in jQuery?

    - by Devyn
    Hi, I know how to move up and down an element in jQuery. $("#div").animate({"left": "+=100"}, 1000); //move 100px to the right But I have no idea to move in diagonal movement. I'm doing chess board and I don't know how to move Bishop with effect. Please have a look at following URL http://chess.diem-project.org/ I did like this... but it's not a proper way. for(var i = 0;i<50;i++){ // move down and move right 1 pixel at a time to get effect $("#div").animate({"left": "+="+x}, 1); $("#div").animate({"top": "+="+x}, 1); } Any idea? Really appreciate your helps!

  • DataGridView Selected Row Move UP and DOWN

    - by Silly Rabbit
    How can I allow selected rows in a DataGridView (DGV) to be moved up or down. I have done this before with a ListView. Unfortunetly, for me, replacing the DGV is not an option (curses). By the way, the DGV datasource is a Generic Collection. The DGV has two buttons on the side, yes, UP & Down. Can anyone help point me in the right direction. I do have the code that I used for the ListView if it'll help (it did not help me).
