• custom wordpress page

  - by sharon

  I'd like to implement a custom post retrieval page in wordpress. Basically, I'm using AJAX to call this page that will be passed a post ID and retrieve certain data from that post. Note: please don't mistake this as a template question. I do not want a template for one single page -- I am looking to make this page query multiple different posts based on postID and return certain data from that post. So I tried creating a page <?php $args=array( 'p'=>'77' ); $friends = new WP_Query($args); ?> <?php if ($friends->have_posts()) : the_post(); ?> <?php the_title(); ?> <?php the_content(); ?> <?php else: ?> <p>Sorry, no posts are available.</p> <?php endif; ?> But this does not work since it is not loading in the wp functions to handle the query. Thanks in advance for any help!

• Delphi 2009 dbExpress and Interbase: Unicode migration steps and risks?

  - by mjustin

  Currently, our database uses Win1252 as the only character encoding. We will have to support Unicode in the database tables soon, which means we have to perform this migration for four databases and around 80 Delphi applications which run in-house in a 24/7 environment. Are there recommendations for database migrations to UTF-8 (or UNICODE_FSS) for Delphi applications? Some questions listed below. Many thanks in advance for your answers! are there tools which help with the migration of the existing databases (sizes between 250 MB and 2 GB, no Blob fields), by dumping the data, recreating the database with UNICODE_FSS or UTF-8, and loading the data back? are there known problems with Delphi 2009, dbExpress and Interbase 7.5 related to Unicode character sets? would you recommend to upgrade the databases to Interbase 2009 first? (This upgrade is planned but does not have a high priority) can we simply migrate the database and Delphi will handle the Unicode character sets automatically, or will we have to change all character field types in every Datamodule (dfm and source code) too? which strategy would you recommend to work on the migration in parallel with the normal development and maintenance of the existing application? The application runs in-house so development and database administration is done internally. Update: one problem I found now is that there are two different persistent field types for Unicode and non Unicode character fields. For the existing database, dbExpress creates TStringField objects. For the Unicode database fields, dbExpress creates (or expects!) TWideStringField objects. This looks like a lot of work lies ahead. While we could try to avoid persistent fields (and add calculated fields at run time), Of course we would prefer a solution which does not require so many changes in existing units and DFM files.

• Backwards compatibility when using Core Data

  - by Alex

  Could anybody shed some light as to why is my app crashing with the following error on iPhone OS 2.2.1 dyld: Symbol not found: _OBJC_CLASS_$_NSPredicate Referenced from: /var/mobile/Applications/456F243F-468A-4969-9BB7-A4DF993AE89C/AppName.app/AppName Expected in: /System/Library/Frameworks/Foundation.framework/Foundation I have weak linked CoreData.framework, and have the Base SDK set to 3.0 and Deployment Target set to SDK 2.2 The app already uses other 3.0 features when available and I did not have any problems with those. But apparently the backward-compatibility methods used for other features do not work with Core Data. The app crashes before app delegate's applicationDidFinishLaunching gets called.

• I need to load a video stored in Applications folder in to a UITableView ?

  - by srikanth rongali

  I need to load a video stored in Applications folder in to a table view. When I touched the cell the video plays. I used the following code to get all the video files in to an array. NSFileManager *fileManager = [NSFileManager defaultManager]; NSArray* contents = [fileManager directoryContentsAtPath:@"/Users/srikanth/Desktop/Projects/UF/Table2/Videos"]; for(a = 1; a < [contents count]; a++) NSLog(@"Array contents: %@", [contents objectAtIndex:a]); cells = [[NSMutableArray alloc]initWithCapacity:[contents count]]; But how can I load the videos into UITableView. I used NSBundle for loading videos by giving path. It worked. But, now I need the videos to load from the array contents. When I touch the cell of the table the corresponding file from the array contents si to be loaded. How can I make it? Thank you.

• How to analyze the efficiency of this algorithm Part 2

  - by Leonardo Lopez

  I found an error in the way I explained this question before, so here it goes again: FUNCTION SEEK(A,X) 1. FOUND = FALSE 2. K = 1 3. WHILE (NOT FOUND) AND (K < N) a. IF (A[K] = X THEN 1. FOUND = TRUE b. ELSE 1. K = K + 1 4. RETURN Analyzing this algorithm (pseudocode), I can count the number of steps it takes to finish, and analyze its efficiency in theta notation, T(n), a linear algorithm. OK. This following code depends on the inner formulas inside the loop in order to finish, the deal is that there is no variable N in the code, therefore the efficiency of this algorithm will always be the same since we're assigning the value of 1 to both A & B variables: 1. A = 1 2. B = 1 3. UNTIL (B > 100) a. B = 2A - 2 b. A = A + 3 Now I believe this algorithm performs in constant time, always. But how can I use Algebra in order to find out how many steps it takes to finish?

• Retrieve position of a google maps v3 marker to Qt in a desktop app with QtWebKit

  - by nelas

  I'm building a Qt app with Python where you can point and click at a (google) map and get the coordinates of the location. The map is shown through a QWebView loading a simple HTML page and the user can create markers by clicking. Screenshot of the widget after clicking on the map: However, I'm having trouble to retrieve the just-clicked location coordinates back to Qt (so that I can use them as variables -- and, for example, show them in the QLineEdits on the topleft corner above, as current location of the marker). This is the relevant part of the HTML file: <script type="text/javascript"> var map; function initialize() { var local = new google.maps.LatLng(-23.4,-40.3); var myOptions = { zoom: 5, center: local, mapTypeId: google.maps.MapTypeId.ROADMAP } map = new google.maps.Map(document.getElementById("map_canvas"), myOptions); google.maps.event.addListener(map, 'rightclick', function(event) { placeMarker(event.latLng); }); } function placeMarker(location) { var clickedLocation = new google.maps.LatLng(location); var marker = new google.maps.Marker({ position: location, map: map }); map.setCenter(location); } function dummyTxt() { return 'This works.'; } </script> I've been trying with evaluateJavaScript, but was not able to retrieve the coordinates. I tried to created a function to access the position with marker.getPosition(), but with no luck. The dummy below works though.. newplace = QWebView.page().mainFrame().evaluateJavaScript(QString('dummyTxt()')) >>> print newplace.toString() This works. Any suggestions on how to get the coordinates back to Qt?

• Sql serve Full Text Search with Containstable is very slow when Used in JOIN!

  - by Bob

  Hello, I am using sql 2008 full text search and I am having serious issues with performance depending on how I use Contains or ContainsTable. Here are sample: (table one has about 5000 records and there is a covered index on table1 which has all the fields in the where clause. I tried to simplify the statements so forgive me if there is syntax issues.) Scenario 1: select * from table1 as t1 where t1.field1=90 and t1.field2='something' and Exists(select top 1 * from containstable(table1,*, 'something') as t2 where t2.[key]=t1.id) results: 10 second (very slow) Scenario 2: select * from table1 as t1 join containstable(table1,*, 'something') as t2 on t2.[key] = t1.id where t1.field1=90 and t1.field2='something' results: 10 second (very slow) Scenario 3: Declare @tbl Table(id uniqueidentifier primary key) insert into @tbl select {key] from containstable(table1,*, 'something') select * from table1 as t1 where t1.field1=90 and t1.field2='something' and Exists(select id from @tbl as tbl where id=req1.id) results: fraction of a second (super fast) Bottom line, it seems if I use Containstable in any kind of join or where clause condition of a select statement that also has other conditions, the performance is really bad. In addition if you look at profiler, the number of reads from the database goes to the roof. But if I first do the full text search and put results in a table variable and use that variable everything goes super fast. The number of reads are also much lower. It seems in "bad" scenarios, somehow it gets stuck in a loop which causes it to read many times from teh database but of course I don't understant why. Now the question is first of all whyis that happening? and question two is that how scalable table variables are? what if it results to 10s of thousands of records? is it still going to be fast. Any ideas? Thanks

• My Zend Framework 'quoting' mess.

  - by tharkun

  I've got a probably very simple issue to which I can't find a satisfactory (subjectively seen) answer in the Zend Framework manual or elsewhere... There are so many ways how I can hand over my php variables to my sql queries that I lost the overview and probably I lack some understanding about quoting in general. Prepared Statements $sql = "SELECT this, that FROM table WHERE id = ? AND restriction = ?"; $stmt = $this->_db->query($sql, array($myId, $myValue)); $result = $stmt->fetchAll(); I understand that with this solution I don't need to quote anything because the db handles this for me. Querying Zend_Db_Table and _Row objects over the API $users = new Users(); a) $users->fetchRow('userID = ' . $userID); b) $users->fetchRow('userID = ' . $users->getAdapter()->quote($userID, 'INTEGER')); c) $users->fetchRow('userID = ?', $userID); d) $users->fetchRow('userID = ?', $users->getAdapter()->quote($userID, 'INTEGER')); Questions I understand that a) is not ok because it's not quoted at all. But what about the other versions, what's the best? Is c) being treated like a statement and automatically quoted or do I need to use d) when I use the ? identifier?

• Using $.get with jquery validation

  - by Jimmy McCarthy

  I'm trying to use the Jquery builtin validator on my page. The issue is that I have certain fields that only are required if the JobID (entered into another field) does not already exist in our database. I have a simple service which simply takes JobID and returns True or False based on whether the JobID exists, but I can't seem to get this information where I want it. Some sample code: $("#dep_form").validate({ rules: { JobID: { required: true, digits: true, minlength: 3 }, OrgName: { required: function(element) { //This field is required if the JobID is new. return $("#jobinfo").html().length==15; } } }, messages: { JobID: { required: "Enter a Job Number.", digits: "Only numbers are allowed in Job ID's.", minlength: "Job Number must be at least 3 digits" }, OrgName: { required: "Select a Practice from the dropdown list." } }, errorClass: "ui-state-error-input", errorLabelContainer: "#errorbox", errorElement: 'li', errorContainer: "#validation_errors", onfocusout: false, onkeyup: false, focusinvalid: false }; Currently, I'm using a lazy method to validate (shown above). However, I now have access to a service using the URL: var lookupurl = "/deposits/jobidvalidate/?q=" + $("#id_JobID").val() + "&t=" + new Date().getTime(); which is a page which will contain just the word True or False based on whether that given JobID exists. I've tried half a dozen different ways of setting variables and calling functions within functions and still cannot get a way to simply return the value of that page (which I've been trying to access with $.get() ) to my validator, so that required is set to true when the Job does not exist and false if the job already exists. Any suggestions? Thanks.

• Why is iPdb not displaying STOUT after my input?

  - by BryanWheelock

  I can't figure out why ipdb is not displaying stout properly. I'm trying to debug why a test is failing and so I attempt to use ipdb debugger. For some reason my Input seems to be accepted, but the STOUT is not displayed until I (c)ontinue. Is this something broken in ipdb? It makes it very difficult to debug a program. Below is an example ipdb session, notice how I attempt to display the values of the attributes with: user.is_authenticated() user_profile.reputation user.is_superuser The results are not displayed until 'begin captured stdout ' In [13]: !python manage.py test Creating test database... < SNIP remove loading tables nosetests ...E.. /Users/Bryan/work/APP/forum/auth.py(93)can_retag_questions() 92 import ipdb; ipdb.set_trace() ---> 93 return user.is_authenticated() and ( 94 RETAG_OTHER_QUESTIONS <= user_profile.reputation < EDIT_OTHER_POSTS or user.is_authenticated() user_profile.reputation user.is_superuser c F /Users/Bryan/work/APP/forum/auth.py(93)can_retag_questions() 92 import ipdb; ipdb.set_trace() ---> 93 return user.is_authenticated() and ( 94 RETAG_OTHER_QUESTIONS <= user_profile.reputation < EDIT_OTHER_POSTS or c .....EE......

• How best to use XPath with very large XML files in .NET?

  - by glenatron

  I need to do some processing on fairly large XML files ( large here being potentially upwards of a gigabyte ) in C# including performing some complex xpath queries. The problem I have is that the standard way I would normally do this through the System.XML libraries likes to load the whole file into memory before it does anything with it, which can cause memory problems with files of this size. I don't need to be updating the files at all just reading them and querying the data contained in them. Some of the XPath queries are quite involved and go across several levels of parent-child type relationship - I'm not sure whether this will affect the ability to use a stream reader rather than loading the data into memory as a block. One way I can see of making it work is to perform the simple analysis using a stream-based approach and perhaps wrapping the XPath statements into XSLT transformations that I could run across the files afterward, although it seems a little convoluted. Alternately I know that there are some elements that the XPath queries will not run across, so I guess I could break the document up into a series of smaller fragments based on it's original tree structure, which could perhaps be small enough to process in memory without causing too much havoc. I've tried to explain my objective here so if I'm barking up totally the wrong tree in terms of general approach I'm sure you folks can set me right...

• iPhone UITableView stutters with custom cells. How can I get it to scroll smoothly?

  I'm using a UITableView to display custom cells created with Interface Builder. The table scrolling isn't very smooth (it "stutters") which leaves me to believe cells aren't being reused. Is there something wrong with this code? - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"TwitterCell"; TwitterCell *cell = (TwitterCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil){ //new cell NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"TwitterCell" owner:nil options:nil]; for(id currentObject in topLevelObjects) { if([currentObject isKindOfClass:[TwitterCell class]]) { cell = (TwitterCell *)currentObject; break; } } } if([self.tweets count] > 0) { cell.lblUser.text = [[self.tweets objectAtIndex:[indexPath row]] username]; cell.lblTime.text = [[self.tweets objectAtIndex:[indexPath row]] time]; [cell.txtText setText:[[self.tweets objectAtIndex:[indexPath row]] text]]; [[cell imgImage] setImage:[[self.tweets objectAtIndex:[indexPath row]] image]]; } else { cell.txtText.text = @"Loading..."; } cell.selectionStyle = UITableViewCellSelectionStyleNone; return cell; }

• C# Help with a basic pedagogic example of a BackGroundWorker process populating a DataGridView

  - by Roger

  Scenario: I have a windows form that holds a DataGridWiew with 3 pre-defined columns. I have 3 variables declared outside the function and assigned to inside the function. I have a function that enumerates stuff and puts it in the 3 columns, line by line: string VARIABLE1; string VARIABLE2; string VARIABLE3; private void FunctionEnumerateStuff() { foreach (StuffObject STUFF in StuffCollection) { VARIABLE1 = STUFF.SubStuff1.ToString(); VARIABLE2 = STUFF.SubStuff2.ToString(); VARIABLE3 = STUFF.SubStuff3.ToString(); DatagridWiew1.Rows.Add(VALUE1, VALUE2, VALUE3); } } What I want to do, is to execute this function from a BackGroundWorker process, so that the GUI of the application will be smooth and responsive. I have read up on backgroundworkers but I am having trouble relating, because all examples seems to be of entirely different scenarios and most of them are overwelmingly complex. San some helpful pedagogic soul help me and others with a very basic example of how to get this to work in the simplest way possible. Thanks.

• Please help me with database connection types in Windows.

  - by Hamish Grubijan

  Sorry for a badly-phrased question. I have a requirement coming from a non-technical person that I need to make sense of. I am basically told: "Here use 'Driver={SQL Server};Server=SERVERNAME\INSTANCENAME;Database=DATABASENAME;Uid=UNAME;Pwd=PASSWORD;'; and here use Server=SERVERNAME\INSTANCENAME;Database=DATABASENAME;Uid=UNAME;Pwd=PASSWORD;';. I am getting no additional help here. While this seems to miraculously fix a bug, I want to understand what is it that I am changing, so I can leave a proper comment for the next developer, plus I can structure the code and name variables differently, depending on the meaning of the change. The work revolves around ASP.net, reporting, SQL Server 2008. Please give me some examples about when you would use one connection string over another. Feel free to edit the question if you can see a way to improve it. When can you lose a 'Driver={SQL Server};? Thank you. EDIT: SQL Server 2008 is the target database, but other can be used ... or maybe will be used in the future.

• What's the best way to develop a debugging window for an ajax ASP.Net MVC application

  - by KallDrexx

  While developing my ASP.NET MVC, I have started to see the need for a debugging console window to assist in figuring out what is going right and wrong in my code. I read the last few chapters of the Pro Asp.net MVC book, and the author details how to use http modules to show page load/creation times and linq to sql query logs, both of which I definitely want to be able to see. However, since I am loading a lot of small sections of my page individually with ajax I don't want the debug information right there in the middle of my screen. So the idea I came up with was to have a separate browser window (open-able by a link or some javascript) with a console log, that can contain logged entries both from javascript and from the asp.net mvc run. The former should be relatively easy, but I'm having trouble coming up with a way to log the asp.net information in ajax requests. The direction I have been thinking of going is to create an httpmodule (like the Pro MVC book does), and have that module contain some that append the javascript's log to console calls with the messages. The issue I see with this is finding a way to get the log messages from the controller's action methods to the httpmodule's methods. The only way I see to do this is with a singleton, but I'm not sure if singletons are bad practice for a stateless web application. Furthermore, it seems like if I return json with my ajax calls (instead of pure html) then that won't work at all anyways and unless there is a way to add data to an existing json structure inside the httpmodule. How does everyone else handle this type of debugging in heavily ajax applications? For reference, the javascript library I am using is jquery.

• Why isn't UIScrollView always calling viewDidLoad on subviews?

  - by Rob S.

  I'm a bit confused on the behaviour of UIScrollView as it pertains to subview loading. In my app, I lazily load subviews into my scroller. Most of the time, -viewDidLoad is called on the subview immediately after adding it the UIScrollView. There is one scenario where it isn't being called. At the 'end' of my scroll view I have a "please wait" view. When it is fully scrolled on to the page, it fades out, I add the subview and -viewDidLoad is not called. In this case, when I remove the last subview and add another subview, I get nothing. I've tried [scrollView setNeedsDisplay] and [scrollView setNeedsLayout] to no avail. I've also sent the same messages to the view I just added - no dice. Does anyone have any insight here? Many people have many questions about -viewDidLoad and I haven't been able to find one related to direct subviews inside of a scrollview. Or I have and I haven't realized it :) Thanks in advance!

• Flash As3 Mute Button problems

  - by Lee

  Hey guys, I am trying to create a UI movie clip that can be used across different scenes. It uses variables from the root scope to determine states. When i press the mute button is works fine, however when i try to un-mute things go weird. Sometimes it takes 2 clicks to unmute, sometimes more. It seems random. Muting however seems to work first time.. Any ideas? Main Timeline: var mute:Boolean = false; var playerName = "Fred"; function setMute(vol) { var sTransform:SoundTransform = new SoundTransform(1,0); sTransform.volume = vol; SoundMixer.soundTransform = sTransform; } function toggleMuteBtn(event:Event) { if (mute) { // Sound On, Mute Off mute = false; setMute(1); ui_mc.muteCross_mc.visible = false; } else { // Sound Off, Mute On mute = true; setMute(0); ui_mc.muteCross_mc.visible = true; } } ui_mc Action Script: if (MovieClip(parent).mute == false) { muteCross_mc.visible = false; } mute_btn.addEventListener(MouseEvent.CLICK, MovieClip(parent).toggleMuteBtn);

• PHP Performance Metrics

  - by bigstylee

  I am currently developing a PHP MVC Framework for a personal project. While I am developing the framework I am interested to see any notable performance by implementing different techniques for optimization. I have implemented a crude BenchMark class that logs mircotime. The problem is I have no frame of reference for execution times. I am very near the beginnig of this project with a database connection and a few queries but no output (bar some debugging text and BenchMark log). I have a current execution time of 0.01917 seconds. I was expecting this to be lower but as I said before I have no frame of reference. I appreciate there are many variables to take into account when juding performance but I am hoping to find some sort of metric to a) techniques to measure performance for example requests per second and b) compare results for example; how a "moderately" sized PHP application on a "standard" webserver will perform. I appreciate "moderately" and "standard" are very subjective words so perhaps a table of known execution times for a particular application (eg StackOverFlow's executing time). What are other techniques of measuring performance are there other than execution time? When looking at MVC Framework Performance Comparisom it talks about Requests Per Second (RPS). How is this calculated? I am guessing with my current execution time of 0.01917 seconds can handle 52 RPS (= 1 / 0.01917 ). This seems to be significantly lower than that quoted on the graph especially when you consider my current limited funcitonality.

• "Decompile" Javascript function? *ADVANCED*

  - by caesar2k

  [1] Ok, I don't even know how to call this, to be honest. So let me get some semi-pseudo code, to show what I'm trying to do. I'm using jquery to get an already existing script declared inside the page, inside a createDocument() element, from an AJAX call. GM_xmlhttprequest({ ... load:function(r){ var doc = document_from_string(r.responseText); script_content = $('body script:regex(html, local_xw_sig)', doc).html(); var scriptEl = document.createElement('script'); scriptEl.type = 'text/javascript'; scriptEl.innerHTML = script_content; // good till here (function(sc){ eval(sc.innerHTML); // not exactly like this, but you get the idea, errors alert('wont get here ' + local_xw_sig); // local_xw_sig is a global "var" inside the source })(scriptEl); } }); so far so good, the script indeed contains the source from the entire script block. Now, inside this "script_content", there are auto executing functions, like $(document).ready(function(){...}) that, everything I "eval" the innerHTML, it executes this code, halting my encapsulated script. like variables that doesn't exist, etc removing certain parts of the script using regex isn't really an option... what I really wanted is to "walk" inside the function. like do a (completely fictional): script = eval("function(){" + script_content + "};"); alert(script['local_xw_sig']); // a03ucc34095cw3495 is there any way to 'disassemble' the function, and be able to reach the "var"s inside of it? like this function: function hello(){ var message = "hello"; } alert(hello.message); // message = var inside the function is it possible at all? or I will have to hack my way using regex? ;P [2] also, is there any way I can access javascript inside a document created with "createDocument"?

• Mysqli query only works on localhost, not webserver

  - by whamo

  Hello. I have changed some of my old queries to the Mysqli framework to improve performance. Everything works fine on localhost but when i upload it to the webserver it outputs nothing. After connecting I check for errors and there are none. I also checked the php modules installed and mysqli is enabled. I am certain that it creates a connection to the database as no errors are displayed. (when i changed the database name string it gave the error) There is no output from the query on the webserver, which looks like this: $mysqli = new mysqli("server", "user", "password"); if (mysqli_connect_errno()) { printf("Can't connect Errorcode: %s\n", mysqli_connect_error()); exit; } // Query used $query = "SELECT name FROM users WHERE id = ?"; if ($stmt = $mysqli->prepare("$query")) { // Specify parameters to replace '?' $stmt->bind_param("d", $id); $stmt->execute(); // bind variables to prepared statement $stmt->bind_result($_userName); while ($stmt->fetch()) { echo $_userName; } $stmt-close(); } } //close connection $mysqli-close(); As I said this code works perfectly on my localserver just not online. Checked the error logs and there is nothing so everything points to a good connection. All the tables exists as well etc. Anyone any ideas because this one has me stuck! Also, if i get this working, will all my other queries still work? Or will i need to make them use the mysqli framework as well? Thanks in advance.
