  • iphone - using a UISwitch

    - by Mike
    I need to implement a view where I need the user to answer several questions using YES or NO. I thought of using a UISwitch but as far as I see it does not allows replacing the ON/OFF messages it shows with YES/NO. Am I wrong? I thought of implementing a segmented control with 2 buttons but this is like using a cannon to kill a fly... Any suggestions on how to do that? thanks

  • Accessing .NET functionality from a macro in a VSTO Excel workbook

    - by Daniel DiPaolo
    A while back, I built an Excel workbook for someone else using VSTO SE, and there's functionality in the accompanying DLL that they'd like to be able to use in a VB macro in the workbook. Short of rebuilding the workbook with a control that does what they want, is there a way they can just hook into the necessary function somehow via some sort of macro call? Does the macro have any sort of visibility into the functionality within the VSTO-built DLL that is associated with the workbook?

  • .net OpenFileDialog changing the CurrentDirectory

    - by meowing
    Hi, I am using OpenFileDialog. But using it changes the Environment.CurrentDirectory. Using the RestoreDirectory property solves this issue, but I'm using external dlls that I can't control that don't use RestoreDirectory. Is there a way to make it true as default? Or is there any other solution to this annoying problem? Thanks.

  • Disable a textbox using CSS

    - by Balaji
    How to disable a textbox in CSS? Currently we are having a textbox in our view which can be enabled/disabled depending on a property in the model. We are having asp.net MVC view; depending on the value of the Model property we need to either render a textbox or readonly textbox. we were thinking of doing this by applying CSS to the view control. Has someone done this earlier?

  • Ignoring svn folders in WinMerge

    - by Martin
    I'm trying to recursively compare two subversion working copy folders using WinMerge. Unfortunately, WinMerge displays lots of differencing files inside of the subversion control folders (.svn or _svn). Is it possible to somehow exclude the subversion folders from the comparision? Or is there another (free) diff-tool which is able to do this?

  • AutoScroll issues with custom layout on Windows Forms application

    - by Lurker Indeed
    I've implemented a basic custom layout engine in Windows Forms that does control sizing and positioning. I was hoping to allow the AutoScroll features to work untouched, but any time I have enough controls on the screen to require a scroll bar, some of the layout events that get fired (i.e, a rich text box that expands the height as it types) not only fire the layout events, but they force the scroll bar back at (0,0). Do I have any options besides looking at the scroll position and positioning the controls manually based on that?

  • Problems when using IconAlignment with WinForms ErrorProvider

    - by Irina
    Hi, I have a ComboBox that has an associated ErrorProvider in the user control it belongs to. When an error happens, I want to display an icon on the left of the combo. However, no matter what value I set as IconAlignment for my combo, the icon gets displayed on the right. Do you guys have any idea what could be wrong here? Thanks for any help.

  • Replace this Hex chars from string in PHP

    - by Guillermo
    I'm generating an XML from data that comes from database (and some JSON feeds). I'm having some problems with some texts that contains some hex chars that are breaking my XML. For example, see this screenshot of the error I get from Chrome: I identified the hex characters that are giving me problems (I believe they're called control characters). And these are: 0x03 0x05 0x16 0x0E How can I replace those characters with PHP before printing them on my XML output? Thanks!

  • Haskell: Left-biased/short-circuiting function

    - by user2967411
    Two classes ago, our professor presented to us a Parser module. Here is the code: module Parser (Parser,parser,runParser,satisfy,char,string,many,many1,(+++)) where import Data.Char import Control.Monad import Control.Monad.State type Parser = StateT String [] runParser :: Parser a -> String -> [(a,String)] runParser = runStateT parser :: (String -> [(a,String)]) -> Parser a parser = StateT satisfy :: (Char -> Bool) -> Parser Char satisfy f = parser $ \s -> case s of [] -> [] a:as -> [(a,as) | f a] char :: Char -> Parser Char char = satisfy . (==) alpha,digit :: Parser Char alpha = satisfy isAlpha digit = satisfy isDigit string :: String -> Parser String string = mapM char infixr 5 +++ (+++) :: Parser a -> Parser a -> Parser a (+++) = mplus many, many1 :: Parser a -> Parser [a] many p = return [] +++ many1 p many1 p = liftM2 (:) p (many p) Today he gave us an assignment to introduce "a left-biased, or short-circuiting version of (+++)", called (<++). His hint was for us to consider the original implementation of (+++). When he first introduced +++ to us, this was the code he wrote, which I am going to call the original implementation: infixr 5 +++ (+++) :: Parser a -> Parser a -> Parser a p +++ q = Parser $ \s -> runParser p s ++ runParser q s I have been having tons of trouble since we were introduced to parsing and so it continues. I have tried/am considering two approaches. 1) Use the "original" implementation, as in p +++ q = Parser $ \s - runParser p s ++ runParser q s 2) Use the final implementation, as in (+++) = mplus Here are my questions: 1) The module will not compile if I use the original implementation. The error: Not in scope: data constructor 'Parser'. It compiles fine using (+++) = mplus. What is wrong with using the original implementation that is avoided by using the final implementation? 2) How do I check if the first Parser returns anything? Is something like (not (isNothing (Parser $ \s - runParser p s) on the right track? It seems like it should be easy but I have no idea. 3) Once I figure out how to check if the first Parser returns anything, if I am to base my code on the final implementation, would it be as easy as this?: -- if p returns something then p <++ q = mplus (Parser $ \s -> runParser p s) mzero -- else (<++) = mplus Best, Jeff

  • .NET RegEx "Memory Leak" investigation

    - by Kevin Pullin
    I recently looked into some .NET "memory leaks" (i.e. unexpected, lingering GC rooted objects) in a WinForms app. After loading and then closing a huge report, the memory usage did not drop as expected even after a couple of gen2 collections. Assuming that the reporting control was being kept alive by a stray event handler I cracked open WinDbg to see what was happening... Using WinDbg, the !dumpheap -stat command reported a large amount of memory was consumed by string instances. Further refining this down with the !dumpheap -type System.String command I found the culprit, a 90MB string used for the report, at address 03be7930. The last step was to invoke !gcroot 03be7930 to see which object(s) were keeping it alive. My expectations were incorrect - it was not an unhooked event handler hanging onto the reporting control (and report string), but instead it was held on by a System.Text.RegularExpressions.RegexInterpreter instance, which itself is a descendant of a System.Text.RegularExpressions.CachedCodeEntry. Now, the caching of Regexs is (somewhat) common knowledge as this helps to reduce the overhead of having to recompile the Regex each time it is used. But what then does this have to do with keeping my string alive? Based on analysis using Reflector, it turns out that the input string is stored in the RegexInterpreter whenever a Regex method is called. The RegexInterpreter holds onto this string reference until a new string is fed into it by a subsequent Regex method invocation. I'd expect similar behaviour by hanging onto Regex.Match instances and perhaps others. The chain is something like this: Regex.Split, Regex.Match, Regex.Replace, etc Regex.Run RegexScanner.Scan (RegexScanner is the base class, RegexInterpreter is the subclass described above). The offending Regex is only used for reporting, rarely used, and therefore unlikely to be used again to clear out the existing report string. And even if the Regex was used at a later point, it would probably be processing another large report. This is a relatively significant problem and just plain feels dirty. All that said, I found a few options on how to resolve, or at least work around, this scenario. I'll let the community respond first and if no takers come forward I will fill in any gaps in a day or two.

  • Populating fields in modal form using PHP, jQuery

    - by Benjamin
    I have a form that adds links to a database, deletes them, and -- soon -- allows the user to edit details. I am using jQuery and Ajax heavily on this project and would like to keep all control in the same page. In the past, to handle editing something like details about another website (link entry), I would have sent the user to another PHP page with form fields populated with PHP from a MySQL database table. How do I accomplish this using a jQuery UI modal form and calling the details individually for that particular entry? Here is what I have so far- <?php while ($linkDetails = mysql_fetch_assoc($getLinks)) {?> <div class="linkBox ui-corner-all" id="linkID<?php echo $linkDetails['id'];?>"> <div class="linkHeader"><?php echo $linkDetails['title'];?></div> <div class="linkDescription"><p><?php echo $linkDetails['description'];?></p> <p><strong>Link:</strong><br/> <span class="link"><a href="<?php echo $linkDetails['url'];?>" target="_blank"><?php echo $linkDetails['url'];?></a></span></p></div> <p align="right"> <span class="control"> <span class="delete addButton ui-state-default">Delete</span> <span class="edit addButton ui-state-default">Edit</span> </span> </p> </div> <?php }?> And here is the jQuery that I am using to delete entries- $(".delete").click(function() { var parent = $(this).closest('div'); var id = parent.attr('id'); $("#delete-confirm").dialog({ resizable: false, modal: true, title: 'Delete Link?', buttons: { 'Delete': function() { var dataString = 'id='+ id ; $.ajax({ type: "POST", url: "../includes/forms/delete_link.php", data: dataString, cache: false, success: function() { parent.fadeOut('slow'); $("#delete-confirm").dialog('close'); } }); }, Cancel: function() { $(this).dialog('close'); } } }); return false; }); Everything is working just fine, just need to find a solution to edit. Thanks!

  • Publishing selection in eclipse RCP

    - by Stuart
    I'm writing an RCP application plug-in. I want to make a set of objects the global selection from a IHandler but this can be triggered from other views out of my control - it is possible that these do not have an ISelectionProvider. Is it possible to publish a selection to the eclipse selection service without going through some view site?

  • MPMoviePlayerController doesn't implement MPMediaPlayback protocol as advertised?

    - by goren
    I'm trying to use the MPMediaPlayback protocol's currentPlaybackRate() to slow down a video. I'm confused though as the class MPMoviePlayerController states that: You can control most aspects of playback programmatically using the methods and properties of the MPMediaPlayback protocol, to which this class conforms. Except just above in the header here: http://developer.apple.com/iphone/library/documentation/MediaPlayer/Reference/MPMoviePlayerController_Class/MPMoviePlayerController/MPMoviePlayerController.html it doesn't seem to. All I want to do is slow down the playback rate for a video.

  • c# WebRequest class and headers

    - by Sir Psycho
    Hi, When I try to set the header properties on a WebRequest object, I get the following exception This header must be modified using the appropriate property I've tried modifying the .Headers propery and adding them that way like so webRequest.Headers.Add(HttpRequestHeader.Referer, "http://stackoverflow.com"); But still getting exceptions. I can get around this by casting the WebRequest object to a HttpWebRequest and setting the properties such as httpWebReq.Referer ="http://stackoverflow.com" But I'd like to know if there's a way to get a finer grained control over modifying headers with a request for a remote resource. Thanks

  • Binding the textDidChange event on a NSTextField to a MacRuby delegate

    - by kolrie
    I have a NSTextField within a Window and I created a very simple MacRuby delegate: class ServerInputDelegate attr_accessor :parent def textDidChange(notification) NSLog notification.inspect parent.filter end end And I have tried setting the control's delegate: I have tried setting the Window and every other object I could think of to this delegate. I have also tried setting it to other delegates (application for instance) and events like applicationDidFinishLaunching are being properly triggered. Is there any trick I am missing in order for this event to be triggered every time the contents of this NSTextField changes?

  • Put any View over a VideoView in Android

    - by abarcia
    It is possible to put any view over a VideoView? (I.e. put the control buttons over the video, like in vimeo). I'm trying to do it using FrameLayout, but I have not found the way, and I'm still not sure if what I'm trying to do something that's is simply not possible.

  • Flex 3 ComboBox skin, limiting text width

    - by Rhys Causey
    I've created a ComboBox skin by extending mx.skins.ProgrammaticSkin. It's working fine, except I can't figure out how to limit the width of the text. Is there a way to control this within the skin? See the attached image for an example of the text going too far. I would like it to stop before the separator line to the left of the down arrow.
