  • Android WebViewClient problem

    - by deSelby
    I've defined a private class that extends WebViewClient and set my WebView's client to an instance of that class (webView01.setWebViewClient(new Callback());). The class definition is as follows: private class Callback extends WebViewClient { public void onLoadResource (WebView view, String url) { } public void onPageStarted (WebView view, String url, Bitmap favicon) { } public void onPageFinished (WebView view, String url) { Animation anim = AnimationUtils.loadAnimation(MyNews.this, R.anim.webviewanim); view.startAnimation(anim); } public void onReceivedError (WebView view, int errorCode, String description, String failingUrl) { } public boolean shouldOverrideUrlLoading (WebView view, String url) { Log.e("loading url", url); return false; } } My problem is that onPageFinished is definitely getting called, but shouldOverrideUrlLoading is never being called. What am I doing wrong here?

  • How to set the content of the $script_for_layout in cakephp?

    - by sipiatti
    Hi, I am learning cakephp in an autodidact manner and I am a complete newbie :) I am creating a simple application. Some logic work so now I going to dive into designing views and layouts. I read the docs and the tutorial but I could not find where to set the content of $script_for_layout. Especially I want to set a $html-css to create link in pages to the stylesheet. I found out that I could do it in directly in the layout template but I would like to create the same link in all pages/views/layouts to the stylesheet so I hope there is a simple way, and avoid to do this in all layouts and/or controllers

  • PHP - Loop thru recordset and fire event each n rows

    - by Luciano
    I'm looking for the right logic to loop thru a recordset and fire an event each n times. Searching on Google i've found some discussion on similar situations, but it seems that solutions don't fits my needs. Let's say i have a recordset of 22 rows. I want to loop thru each row and launch a function on the 4th, the 8th, the 12th and so on... Using the modulus operator as shown in this answer, if($i % 4 == 0), i get the event fired each 4 rows, but 22 its not a multiple of 4 so the event is fired till the 20th row and then nothing. Maybe i need to make a division counting rows in 'excess'? Since the recordset will be between 50 and 200 rows i think its not necessary run multiple query of 4 rows, am I wrong? Thanks in advance!

  • Call an IOUSBDeviceInterface function on an obj-c object instead of a C structure

    - by b1onic
    Let's say I want to close an USB device. Here is a C structure representing the USB device: struct __USBDevice { uint16_t idProduct; io_service_t usbService; IOUSBDeviceInterface **deviceHandle; IOUSBInterfaceInterface **interfaceHandle; Boolean open; }; typedef struct __USBDevice *USBDeviceRef; Here is the code to close the device: // device is a USBDeviceRef structure // USBDeviceClose is a function member of IOUSBDeviceInterface C Pseudoclass (*device->deviceHandle)->USBDeviceClose(device->deviceHandle); Now imagine that the device properties are declared in an obj-c class @interface Device : NSObject { NSNumber idProduct io_service_t usbService; IOUSBDeviceInterface **deviceHandle; IOUSBInterfaceInterface **interfaceHandle; BOOL open; } @end How would I do to call USBDeviceClose() ?

  • How do I detect a change of tab page in TabControl prior to SelectedIndexChanged event?

    - by JYelton
    I currently determine what page of a tabcontrol was clicked on via the SelectedIndexChanged event. I would like to detect before the selected index actually changes, for validation purposes. For example, a user clicks a tab page other than the one they are viewing. A dialog is presented if form data is unsaved and asks if it's ok to proceed. If the user clicks no, I'd like to remain on the current tab. Currently I have to remember the previous tab page and switch back to it after an answer of 'no.' I considered MouseDown (and the assorted calculation logic), but I doubt that's the best way. (This is in .NET C# 3.5)

  • Zend Dd Rowset getting parent row

    - by simple
    I am wondering about using the abstraction in Zend Db RowSet instead of joins, is it possible for instance I am able to get some info from parent table as in here /** * Get default photo info (path , description) */ public function getDefaultPhotoInfo($userdId){ $select = $this->select($this) ->where('id=?', $userdId); $rowset = $this->fetchAll($select); $current = $rowset->current(); $res = $current->findParentRow('UserPhotos', 'Avatar'); if(isset($res)){ return $res->toArray(); } } How can I use Rowset abstraction to get this logic working table( id, pic_path,) table_translation(id, table_id, lang_id, pic_title); the above is representation of two tables , the idea is to get the info from both table specifying the lang_id , it is easy with joins but can I do it with the abstraction of Db Rowset ?

  • GUI designers! - got suggestions for a GUI modelling diagram language?

    - by naugtur
    Refering to this question I asked a while ago: UI functionality modeling languages It looks like there is no good-enough solution. I decided to develop one. (and prepare a set of elements for DIA or something) I'm sure it will require a good insight in peoples' experiences and problems in designing functionally complicated GUIs. I've got some ideas already, but I'd like to hear from You what You'd expect from a GUI functionality modelling language. Clarification: It's functionality modelling, so it's not about where I put a button. It's about objects that have some events binded, and the interface behaviour logic. If You think (just as I do) that UML is far from useful for such purposes - feel free to put Your expectations here. I'll try to meet them. ( not necessarily in person;) ) Remember - there is no such thing as a wrong answer to this question

  • PHP Comparing 2 Arrays For Existence of Value in Each

    - by Dr. DOT
    I have 2 arrays. I simply want to know if one of the values in array 1 is present in array 2. Nothing more than returning a boolean true or false Example A: $a = array('able','baker','charlie'); $b = array('zebra','yeti','xantis'); Expected result = false Example B: $a = array('able','baker','charlie'); $b = array('zebra','yeti','able','xantis'); Expected result = true So, would it be best to use array_diff() or array_search() or some other simple PHP function? Thanks!

  • In the java DBCP connection pool - what is an idle connection?

    - by Ravenor
    A colleague at work insists that a DBCP idle connection is a connection that has lain unused for 30 minutes. I believe a dbcp idle connection is a connection that is in the pool available to be borrowed, and an active connection is one that is borrowed. Looking through the code I found no reference to 30 minutes or other magic values and a cursory glance through the code for assuring minidle does not show any such logic. If he is correct can you please back that up with a code or documentation reference. For the complete answer I would like it answered for both DBCP 1.1 and 1.6.

  • PHP is there a true() function?

    - by Gremo
    I'm writing a function to check all elements inside an array, returning a single boolean value. is there a true() function? function all($f, array $arr) { return empty($arr) ? false : array_reduce($arr, function($v1, $v2) use ($f) { return $f($v1) && $f($v2); }, true); } $test = array(1, 6, 2); $gte0 = function($v) { return $v >= 0; } var_dump(all($gte0, $test)); // True $test = array(true, true, false); $id = function($v) { return $v; } // <-- this is what i would avoid var_dump(all($id, $test)); // False all(true, $test); // NOT WORKING because true is not a function

  • Android; Confused by views?

    - by javano
    I have created a class (InputControl) which extends the view of my main class (Main), and takes focus of the screen. I have a button on the main xml layout which calls control() and sets up my InputControl view, from there I capture user input. How can I return back to the xml layout from the InputControl view class? public class Main extends Activity { public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); InputControl = new InputControl(this); } //......SNIP! public void control(){ setContentView(InputControl); InputControl.requestFocus(); } } public class InputControl extends View implements OnTouchListener { public InputControl(Context context) { super(context); setFocusable(true); setFocusableInTouchMode(true); this.setOnTouchListener(this); } public boolean onTouch(View view, MotionEvent event) { //...I AM CAPTURING USER TOUCH EVENTS HERE } }

  • MySQL triggers cannot update rows in same table the trigger is assigned to. Suggested workaround?

    - by Cory House
    MySQL doesn't currently support updating rows in the same table the trigger is assigned to since the call could become recursive. Does anyone have suggestions on a good workaround/alternative? Right now my plan is to call a stored procedure that performs the logic I really wanted in a trigger, but I'd love to hear how others have gotten around this limitation. Edit: A little more background as requested. I have a table that stores product attribute assignments. When a new parent product record is inserted, I'd like the trigger to perform a corresponding insert in the same table for each child record. This denormalization is necessary for performance. MySQL doesn't support this and throws: Can't update table 'mytable' in stored function/trigger because it is already used by statement which invoked this stored function/trigger. A long discussion on the issue on the MySQL forums basically lead to: Use a stored proc, which is what I went with for now. Thanks in advance!

  • database vs flat file, which is a faster structure for regex matching with many simultaneous request

    - by Jamex
    Hi, which structure returns faster result and/or less taxing on the host server, flat file or database (mysql)? Assume many users (100 users) are simultaneously query the file/db. Searches involve pattern matching using regex against a static file/db. File has 50,000 unique lines (same data type). There could be many matches. There is no writing to the file/db, just read. Is it possible to have a duplicate the file/db and write a logic switch to use the backup file/db if the main file is in use? Which language is best for the type of structure? Perl for flat and PHP for db? TIA

  • Service Layer Pattern - Could we avoid the service layer on a specific case?

    - by lidermin
    Hi, we are trying to implement an application using the Service Layer Pattern cause our application needs to connect to other multiple applications too, and googling on the web, we found this link of a demonstrative graphic for the "right" way of apply the pattern: martinfowler.com - Service Layer Pattern But now we have a question: what if our system needs to implement some business logic, only for our application (like some maintenance data for the system itself) that we don't need to share with other systems. Based on this graphic: As it seems, it will be unnecesary to implement a service layer just for that; it will be more practical to avoid the service layer, and just go from User Interface to the Business Layer (for example). What should be the right way in this case to implement the Service Layer Pattern? What do you suggest us for a scenario like the one I told you? Thanks in advance.

  • SQL Server - Compare int values in a select clause

    - by Russell
    This is what I thought would be a simple select clause, however the following is giving me grief! I am using SQL Server 2008. Basically I want to compare two integer values and return the boolean result in the select clause. Here is a simple example: DECLARE @A INT DECLARE @B INT SET @A = 1 SET @B = 2 SELECT @A = @B Currently the only output is "Command(s) completed successfully." Where I reasonably believe it is assigning @A to @B. I thought this would be simple but have not been able to achieve this. Any help would be great! Thanks

  • Parameter passing Vs Table Valued Parameters Vs XML to SQL 2008 from .Net Application

    - by Harryboy
    As We are working on a asp .net project there three ways one can update data into database when there are multiple rows updation / insertion required Let's assume we need to update employee education detail (which could be 1,3,5 or 10 records) Method to Update Data Pass value as parameter (Traditional approach), If 10 records are there then 10 round trip required Pass data as xml and write logic inside your stored procedure to get that data from xml and update the table (only single roundtrip required) Use Table valued parameters (only single roundtrip required) Note : Data is available as List, so i need to convert it to xml or any other format if i need to pass. There are no. of places in entire application we need to update data in bulk (or multiple records) I just need your suggestions that Which method will be faster (please mention if there are some other overheads) Manageability or testability concern with any approach Any other bottleneck or issue with any of the approach (Serialization /Deserialization concern or limit on size of the data passing) Any other method you suggest for same operations Thanks

  • How do I understand what the following means?

    Quoted from here: if (to_end) { /* If we want to scroll to the end, including horizontal scrolling, * then we just create a mark with right gravity at the end of the * buffer. It will stay at the end unless explicitely moved with * gtk_text_buffer_move_mark. */ gtk_text_buffer_create_mark (buffer, "end", &iter, FALSE); /* Add scrolling timeout. */ return g_timeout_add (50, (GSourceFunc) scroll_to_end, textview); } else { /* If we want to scroll to the bottom, but not scroll horizontally, * then an end mark won't do the job. Just create a mark so we can * use it with gtk_text_view_scroll_mark_onscreen, we'll position it * explicitely when needed. Use left gravity so the mark stays where * we put it after inserting new text. */ gtk_text_buffer_create_mark (buffer, "scroll", &iter, TRUE); /* Add scrolling timeout. */ return g_timeout_add (100, (GSourceFunc) scroll_to_bottom, textview); } Though there are quite a few lines of comments, I still don't understand the logic in it,especially, what's the relation between an mark and the position of scroll bar?

  • How do you use Java 1.6 Annotation Processing to perform compile time weaving?

    - by Steve
    I have created an annotation, applied it to a DTO and written a Java 1.6 style annotationProcessor. I can see how to have the annotationProcessor write a new source file, which isn't what I want to do, I cannot see or find out how to have it modify the existing class (ideally just modify the byte code). The modification is actually fairly trivial, all I want the processor to do is to insert a new getter and setter where the name comes from the value of the annotation being processed. My annotation processor looks like this; @SupportedSourceVersion(SourceVersion.RELEASE_6) @SupportedAnnotationTypes({ "com.kn.salog.annotation.AggregateField" }) public class SalogDTOAnnotationProcessor extends AbstractProcessor { @Override public boolean process(final Set<? extends TypeElement> annotations, final RoundEnvironment roundEnv) { //do some stuff } }

  • mysql: select ... where id = any value. is it possible?

    - by Syom
    look at this table please table |id| |name| |order| i must get the rows, where name = something and order = somevalue so i write select `id` from `table` where `name` = 'something' and `order` = 'somevalue' but depend on php logic, sometimes i need to get all rows, where name = somethimg, independently of order value. i don't want to change the query structure, because in practise there are many number of fields, and possible count of queries will became very big. so i want to save the structure of query, and when i need to select just by name, i want to write something like this select `id` from `table` where `name` = 'something' and `order` = any value is it possible? maybe the question is incomprehensible, at least i tried;) sorry for bad english thanks
