• can I auto update my uitextview from the value of the row of my uipickerview without pressing any se

  - by Wesley

  So I have a uipicker view, that I have managed to load some data from my db into. I would like to update a textview, which is right above the pickerview, with each changing of the row. Is that possible? If I don't have to, I would like to avoid pushing a button in order to show the respective text. Can I make it so that the value in the text field changes with the value of the rowselected in the pickerview, in real time? Any thoughts or code snippets would be appreciated. Thanks!

• Must I loop to search results for a specific value?

  - by tag

  I have a table in the database: name Opinion Tim Tim has an opinion John other random text Dan Dan's random text Al Al says something else I call this data and get it back in getRecords.lastResult To access John's opinion, I could use: getRecords.lastResult[1].opinion But that's only because I know that John is the second record (record 1), but this may change. So the right way is to search through the results to first find the record index for John, then access his opinion. My guess is I need some sort of a loop? Is there an easier way to search for John directly without a loop?

• Is there a way to catch a MOUSE_UP Event over a static textfield in Flash?

  - by Jovica Aleksic

  When the user presses the mouse, and releases it over a static textfield with selectable text, no MOUSE_UP event is fired - not on the stage and also nowhere else. I experienced this when using a scrollbar class on a movieclip with a nested static textfield. When the user drags the scroll handle and releases the mouse over the textfield, the dragging/scrolling is stuck. To test this, create a new AS3 fla file, place a static textfield somewhere, and put in some text. Make sure the selectable property is checked in the properties panel. Add this script to the timeline: import flash.events.* function down(event:Event):void { trace('down'); } function up(event:Event):void { trace('up'); } stage.addEventListener(MouseEvent.MOUSE_DOWN, down) stage.addEventListener(MouseEvent.MOUSE_UP, up) Now test the movie and click the mouse. You will notice that trace('up') will not occur when you release the mouse over the textfield.

• Tentative date casting in tsql

  - by Tewr

  I am looking for something like TRYCAST in TSQL or an equivalent method / hack. In my case I am extracting some date data from an xml column. The following query throws "Arithmetic overflow error converting expression to data type datetime." if the piece of data found in the xml cannot be converted to datetime (in this specific case, the date is "0001-01-01" in some cases). Is there a way to detect this exception before it occurs? select [CustomerInfo].value('(//*:InceptionDate/text())[1]', 'datetime') FROM Customers An example of what I am trying to achieve in pseudocode with an imagined tsql function TRYCAST(expr, totype, defaultvalue): select TRYCAST( [CustomerInfo].value('(//*:InceptionDate/text())[1]', 'nvarchar(100)'), datetime, null) FROM Customers

• Can't get message body of certain emails from inbox using the Zend framework?

  - by Ali

  Hi guys I'm trying to read through an email inbox for my application - I'm using the zend framework here. The problem is that I'm unable to retrieve the message body for certain emails. The following is my code as to how I'm doing this: $mail = new Zend_Mail_Storage_Imap($mail_options); $all_messages = array(); $page = isset($_GET['page'])?$_GET['page']:1; $limit = isset($_GET['limit'])?$_GET['limit']:20; $offset = (($page-1)*$limit)+1; $end = ($page*$limit)>$c?$c:($page*$limit); for ($i=$offset;$i<=$end;$i++){ $h2t = new html2text(); $h2t->set_allowed_tags('<a>'); if(!$mail[$i]) break; else{ $one_message = $mail->getMessage($i); $one_message->id = $i; $one_message->UID = $mail->getUniqueId($i); $one_message->parts = array(); $one_message->body = ''; $count = 1; foreach (new RecursiveIteratorIterator($mail->getMessage($i)) as $ii=>$part) { try { $tpart = $part; //$tpart->_content = ''; $one_message->parts[$count] = $tpart; $count++; // check for html body if (strtok($part->contentType, ';') == 'text/html') { $b = $part->getContent(); if($part->contentTransferEncoding == 'quoted-printable') $b = quoted_printable_decode($b); $one_message->html_body = $b; $h2t->set_html($b); $one_message->body = $h2t->get_text(); } //check for text body if (strtok($part->contentType, ';') == 'text/plain') { $b = $part->getContent(); if($part->contentTransferEncoding == 'quoted-printable') $b = quoted_printable_decode($b); $one_message->text_body = $b; $one_message->body = $b;//$part->getContent(); } } catch (Zend_Mail_Exception $e) { // ignore } } $all_messages[] = $one_message; } } The problem is that randomly some messages don't return even a textbody or an html body. Even though if I check using a webvmail client those emails have a message body as well. WHat am I missing here?

• Disappearing Windows Explorer pinned items

  - by surfmadpig

  This has happened twice now in three months: After rebooting, ALL the pinned items from my Windows Explorer taskbar jumplist are gone. Also, recent items from Windows Explorer are much fewer, only one or two if I remember correctly. After the first time I re-pinned the items I wanted, but about a month later it happened again. I re-pinned All other pinned items in other jumplists (e.g. Word) are fine and have never disappeared. Googling for the problem showed that ccleaner can affect this, but I personally do NOT use any cleaners or related progs on this machine. I also think that both times it happened it was after a windows update, although I can't recall what kind of update it was. After each time, Little Registry Editor showed invalid references in HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\RecentDocs , but I had NOT used it prior to the deletions. Any ideas on why this happens and how to prevent it?

• MySQL - Sort on a calculated value based on two dates

  - by Petter Magnusson

  I have the following problem that needs to be solved in a MySQL query: Fields info - textfield date1 - a date field date2 - a date field offset1 - a text field with a number in the first two positions, example "10-High" offset2 - a text field with a number in the first two positions, example "10-High" I need to sort the records by the calculated "sortvalue" based on the current date (today): If today=date2 then sortvalue=offset1*10+offset2*5+1000 else sortvalue=offset1*10+offset2*5 I have quite good understanding of basic SQL with joins etc, but this I am not even sure if its possible...if it helps I could perhaps live with a single formula giving the same sort of effect as the IFs do....ie. before date1 = low value, after date2 = high value...

• compare the contents of two folders that are replicating by dfs

  - by Funky Si

  I have a large folder that I am replicating by dfs and I want to check that all files have been replicated correctly. Currently I am running the following script at both ends. cd e:\data\shared\ dir /a:-h /b /s > e:\data\shared\result.txt and then using a text editor to tidy the file before using a diff tool to compare them. Does anyone know a better way of doing this? Failing that does anyone know how to adapt my script to ignore all the files in the DfsrPrivate folders

• the best "Simple" CMS system suitable for .Net MVC

  - by Truegilly

  Hello, I'm developing a MVC .Net site and would like to implement a CMS system. So far I have looked at Umbraco, which looks good but the help is poor and the getting started video section is empty, and dotnetnuke, which again looks good but I get the impression its aimed at non developers, plus to has much more than I need and want. In my last job I created a basic custom CMS system that worked by simply adding values into the database, the application called the text from there. it worked fine but I don’t have the source code. what I'm after is a simple CMS system that really just controls text and images, I dont need all the fancy stuff thats in umbraco and dotnetnuke, all the design and CSS i can do myself. also as im working with MVC (which is awesome, and such a breath of fresh air compared to the web forms/telerik crap I have to put up with at work) it needs to be compatible. A simple CMS, can anyone provide any suggestion ? Truegilly

• What is the best way, if possible, to send information from a Java PrintStream to a JTextPane?

  - by Daniel Reeves

  In Java, I have a package that translates XML metadata from one standard to another. This package is ultimately accessed through a single function and sends all of its output through a PrintStream object. The output sent is just a status of each file and whether or not it was translated. This is pretty fine and dandy if I'm just printing to System.out, but I'm actually wanting to print this to a JTextPane while it translates (kind of like a progress text box). It wouldn't be a big deal to just print the status after it was done translating the XML, but since there may be thousands of XML files, that's just not feasible. One thing that I've tried is to use a thread that takes all of the information from the PrintStream (which is attached to a ByteArrayOutputStream) and let it send any new information to the text pane. Unfortunately, this still sends the information all at once at the end of the translation. This does work correctly for System.out. Here's the code that does the translation and tries to show the output: public class ConverterGUI extends javax.swing.JFrame { boolean printToResultsBox = false; PrintStream printStream = null; ByteArrayOutputStream baos = null; private class ResultsPrinter implements Runnable { public ResultsPrinter() { baos = new ByteArrayOutputStream(); printStream = new PrintStream(baos); } public void run() { String tempString = ""; while (printToResultsBox) { try { if (!baos.toString().equals(tempString)) { tempString = baos.toString(); resultsBox.setText(tempString); } } catch (Exception ex) { } } } } ... ResultsPrinter rp = new ResultsPrinter(); Thread thread = new Thread(rp); thread.start(); // Do the translation. try { printToResultsBox = true; boolean success = false; TranslationEngine te = new TranslationEngine(); // fileOrFolderToConvert is a text box in the GUI. // linkNeeded and destinationFile are just parameters for the translation process. success = te.translate(fileOrFolderToConvert.getText(), linkNeeded, destinationFile, printStream); if (success) { printStream.println("File/folder translation was a success."); } resultsBox.setText(baos.toString()); } catch (Exception ex) { printStream.println("File translation failed."); } finally { printToResultsBox = false; } ... } Ultimately, this code prints out to the JTextPane just fine after all the translation is done but not during. Any suggestions? Do I need to change the PrintStream to something else?

• XSL: Dead or not dead

  - by Seattle Leonard

  I'm currently taking on a new project at home. In this project I'm going to be generating HTML emails. For this purpose, I believe XSL to be a good candidate. However, I have heard people say that XSL is a dead language, and if it's not that it is on it's way out. In fact, MS has been very leary to support XSL 2.0. Personally I feel that any time you are going from text to text, it is a great tool. Such as: Generating HTML e-mails Creating Open Office Docs Generating another XML doc What are your thoughts? Is it dead, or is it still a viable, usefull tool?

• Save UITextView content in NSString.

  - by camilo

  Hi, I'm trying to save the contents of an UITextView into a NSString which I will somehow persist later. The problem is that the UITextView "text" property doesn't save all the rows in the textView (after touching "return"). I tried print the TextView object and the textView.text, and they're different. Does anybody know how (after editing the textView) I can save its content into a String (or something else that I can later access and share through different views and persist in the database)? Thanks a lot. Pretty sure it is simple, but I'm honestly not finding the solution.

• iPhone app rejected because of Beta word is used

  - by arielcamus

  Hi, I was using the text "We are currently on Beta. Please, enter our website and ask for an invitation" when a user click on "Register" on our app. However, Apple has rejected our app because it can not has any disabled featured and can not contains word "Beta". What would you do in this situation? I don't know if hide this option and show it only when an API call response says "registerEnabled = YES" or just change the text and use: "You need and invitation to access OUR_APP. Visit our website to get one." Except for registering, our app is fully functional. Thank you, A

• When I really need to use [NSThread sleepForTimeInterval:1];

  - by Timbo

  Hi there, I have a program that needs to use sleep. Like really needs to. In lieu of spending ages explaining why, suffice to say that it needs it. Now I'm told to split off my code into a separate thread if it requires sleep so I don't lose interface responsiveness, so I've started learning how to use NSThread. I've created a brand new program that is conceptual so to solve the issue for this example will help me in my real program. Short story is I have a class, it has instance variables and I need a loop with a sleep to be depended on the value of that instance variable. Here's what I've put together anyway, your help is very much appreciated :) Cheers Tim /// Start Test1ViewController.h /// #import <UIKit/UIKit.h> @interface Test1ViewController : UIViewController { UILabel* label; } @property (assign) IBOutlet UILabel *label; @end /// End Test1ViewController.h /// /// Start Test1ViewController.m /// #import "Test1ViewController.h" #import "MyClass.h" @implementation Test1ViewController @synthesize label; - (void)viewDidAppear:(BOOL)animated { [super viewDidAppear:animated]; label.text = @"1"; [NSThread detachNewThreadSelector:@selector(backgroundProcess) toTarget:self withObject:nil]; } - (void)backgroundProcess { NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; // Create an instance of a class that will eventually store a whole load of variables MyClass *aMyClassInstance = [MyClass new]; [aMyClassInstance createMyClassInstance:(@"Timbo")]; while (aMyClassInstance.myVariable--) { NSLog(@"blah = %i",aMyClassInstance.myVariable); label.text = [NSString stringWithFormat:@"blah = %d", aMyClassInstance.myVariable]; //how do I pass the new value out to the updateLabel method, or reference aMyClassInstance.myVariable? [self performSelectorOnMainThread:@selector(updateLabel) withObject:nil waitUntilDone:NO]; //the sleeping of the thread is absolutely mandatory and must be worked around. The whole point of using NSThread is so I can have sleeps [NSThread sleepForTimeInterval:1]; } [pool release]; } - (void)updateLabel {label.text = [NSString stringWithFormat:@"blah = %d", aMyClassInstance.myVariable]; // be nice if i could } - (void)didReceiveMemoryWarning {[super didReceiveMemoryWarning];} - (void)viewDidUnload {} - (void)dealloc {[super dealloc];} @end /// End Test1ViewController.m /// /// Start MyClass.h /// #import <Foundation/Foundation.h> @interface MyClass : NSObject { NSString* name; int myVariable; } @property int myVariable; @property (assign) NSString *name; - (void) createMyClassInstance: (NSString*)withName; - (int) changeVariable: (int)toAmount; @end /// End MyClass.h /// /// Start MyClass.h /// #import "MyClass.h" @implementation MyClass @synthesize name, myVariable; - (void) createMyClassInstance: (NSString*)withName{ name = withName; myVariable = 10; } - (int) changeVariable: (int)toAmount{ myVariable = toAmount; return toAmount; } @end /// End MyClass.h ///

• Java regex basic usage problem

  - by Ernelli

  The following code works: String str= "test with foo hoo"; Pattern pattern = Pattern.compile("foo"); Matcher matcher = pattern.matcher(str); if(matcher.find()) { ... } But this example does not: if(Pattern.matches("foo", str)) { ... } And neither this version: if(str.matches("foo")) { ... } In the real code, str is a chunk of text with multiple lines if that is treated differently by the matcher, also in the real code, replace will be used to replace a string of text. Anyway, it is strange that it works in the first version but not the other two versions.

• How do I execute a sequence of servlets?

  - by Legend

  I have some servlets that act as individual URLs for populating a database for some dummy testing. Something of the form: public class Populate_ServletName extends HttpServlet { public void doGet(HttpServletRequest req, HttpServletResponse resp) throws IOException { resp.setContentType("text/plain"); //Insert records //Print confirmation } } I have about 6 such servlets which I want to execute in a sequence. I was thinking of using setLocation to set the next page to be redirected but was not sure if this is the right approach because the redirects should happen after the records have been inserted. Specifically, I am looking for something like this: public class Populate_ALL extends HttpServlet { public void doGet(HttpServletRequest req, HttpServletResponse resp) throws IOException { resp.setContentType("text/plain"); //Call Populate_1 //Call Populate_2 //Call Populate_3 //... } } Any suggestions?

• How to avoid timestamp issue in a long query?
