  • vaadin custom layout setting a text area in a table with the location attribute

    - by user3717298
    I need to set a text area in the html template and use it as a custom component in vaadin the html snippet is as below <table> <tr> <td> JUNK SENTENCE </td> <td> <div location="HEADIN"></div> <div location="Details"></div> <div location="Attachment"></div> </td> <td> <p>School of more than 50 students univer versities.</p> </td> </tr> </table> All the place holders are working and displays data but the "details" holder should be a text area. as the text is a lot over there so I tried the below way but it just turned the place holder to text vaadin could not manipulate / identify the "Details" place holder. I tried the below way i set - in side the text area tag. <textarea rows="4" cols="50"> </textarea> and again i tried this way too which also did not work. <textarea rows="4" cols="50" location="Details"> </textarea> Any guidance would be appreciated to solve this I am setting the needed values from a formfeildfactory and these values are set by implementing the Vaadin Custom field class(in case it helps some more to identify)

  • VS2010 and CSS: What is the best way to position a single form control

    - by George
    OK, I have a ton of controls on my page that I need to individually place. I need to set a margin here, a padding there, etc. None of these particular styles that I want to apply will be applied to more than control. What is the bets practice for determining at which level the style is placed, etc? OK, my choices are 1) External CSS file 1A) Using ClientIdMode = Auto (the default) I could assign a unique CssClass value to the ASP.NET control and, in the external CSS file, create a class selector that would only be applied to that one control. 1B) User Client ID = Predicatable In the external CSS file, I could determine what the ID will be for the controls of interest and create an ID selector (#ControlID{Style} ). However, I fear maintenance issues due to including/removing parent containers that would cause the ID to change. 1C) User Client ID = Static. I could choose static IDs for the controls such that I minimize the likelihood of a clash with auto generated IDs (perhaps by prefixing the ID with "StaticID_" and use an external stylesheet with ID selectors. 2) I could place the style right on the control. The only disadvantage here, as I see it, is that style info is brought down each time instead of being cached , which is what I'd get using an external CSS. If a style isn't resused, I personally don't see much benefit to placing it in an external file, though please explain why if you disagree. Is there moire of a reason that "It's nice to have all the CSS in one place?"

  • post values to external page explicitly PHP

    - by JPro
    Hi, I want to post values to a page through a hyperlink in another page. Is it possible to do that? Let's say I have a page results.php which has the starting line, <?php if(isset($_POST['posted_value'])) { echo "expected value"; // do something with the data } else { echo "no the value expected"; } If from another page say link.php I place a hyperlink like this: <a href="results.php?posted_value=1"> , will this be accepetd by the results page? If instead if I replace the above starting line with if(isset($_REQUEST['posted_value'])), will this work? I believe the above hyperlink evaluates to GET, but since the only visibility difference between GET and POST that is you can see parameters in the address bar with GET But, is there any other way to place a hyperlink which can post values to a page? or can we use jquery in the place of hyperlink to POST the values? Can anyone please suggest me something on this please? Thanks.

  • Placing and removing element on array trough object

    - by Chris
    Hello, Lets assume i have 2 methods 1 that places a element on the array and one that removes it. const int Max = 10; int[] table= new int[Max]; I would like to call it up like this: s1.Place(5); // 5 0 0 0 0 0 0 0 0 0 0 s1.Place(9); // 5 9 0 0 0 0 0 0 0 0 0 s1.Remove(9); // 5 0 0 0 0 0 0 0 0 0 0 I would only like to use : using system for this. The result i get right now when i run the program is s1 = "nameofprogram" "name of class object" Normally i should get 0 0 0 0 0 0 0 0 0 0 to begin with. Any ideas how i can exactly add or remove those elements on the array? public void Place(int g) { if (top == Max) { throw new Exception("Stack overflow..."); } else { table[top] = g; top++; } ....

  • Utility App with Navigation Controller and Table View on FlipSide.

    - by wdt
    Hi All. I am relatively new to the whole MVC way of looking at things. I have an application that is based on the "Utility" Application template. Everything in the MainView and FlipsideView is working great but now I need to add a TableView and Navigation Controller to the flipside. Without the navigation bar being on the MainView. So only once the user has tapped the info light button will the nav bar display on the flipside with a table view. I have been able to impliment the Table View on the side and populate it with data from an array. I am now struggling to link in a navigation controller so that the tableview can become interactive. When I place the nav bar code into the app delegate it appears on the MainView and not the flipside view. Where do I place the navigation bar code so that it will display on the flipsideview. I cannt seem to get the code in the right place. Also I am not sure I have the right code, do I put the UINavigationController code in the FlipSideViewController.m ? I am not grasping the concept of the naivgation controller fully I think . . . Here is the code to bring up the FlipView - (IBAction)showInfo { TableViewController *controller = [[TableViewController alloc] initWithNibName:@"TableViewController" bundle:nil]; controller.delegate = self; controller.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; [self presentModalViewController:controller animated:YES]; [controller release]; } Now I need to get the TableViewController to have a navigation controller and a table view Thanks in advance.

  • Intelligently removing excess indention from a string

    - by TravisO
    I'm trying to remove some excessive indention from a string, in this case it's SQL, so it can be put into a log file. So I need the find the smallest amount of indention (aka tabs) and remove it from the front of each line, but the following code ends up printing out exactly the same, any ideas? In other words, I want to take the following SELECT blah FROM table WHERE id=1 and convert it to SELECT blah FROM table WHERE id=1 here's the code I tried and fails $sql = ' SELECT blah FROM table WHERE id=1 '; // it's most likely idented SQL, remove any idention $lines = explode("\n", $sql); $space_count = array(); foreach ( $lines as $line ) { preg_match('/^(\t+)/', $line, $matches); $space_count[] = strlen($matches[0]); } $min_tab_count = min($space_count); $place = 0; foreach ( $lines as $line ) { $lines[$place] = preg_replace('/^\t{'. $min_tab_count .'}/', '', $line); $place++; } $sql = implode("\n", $lines); print '<pre>'. $sql .'</pre>';

  • Host a IWpfTextView in a custom tool for a Visual Studio Extension

    - by Adam Driscoll
    I'm trying to create a IWpfTextView and then put it into a custom tool window. I can create the view, read a file to populate the ITextBuffer and display the view into my tool. I cannot edit the code at all and the code is not syntax highlighted. What steps am I missing to make this a full fledged editor? Code: IComponentModel componentModel = (IComponentModel)GetGlobalService (typeof(SComponentModel)); var _textEditorFactoryService = componentModel.GetService<ITextEditorFactoryService>(); var _textBufferFactoryService = componentModel.GetService<ITextBufferFactoryService>(); var _contentTypeRegistryService = componentModel.GetService<IContentTypeRegistryService>(); TextReader reader = new StreamReader(fileName); var types = _contentTypeRegistryService.GetContentType("CSharp"); ITextBuffer textBuffer = _textBufferFactoryService.CreateTextBuffer(reader, types); var view = _textEditorFactoryService.CreateTextView(textBuffer); IWpfTextViewHost editor = _textEditorFactoryService.CreateTextViewHost(view, true);

  • dinamically resizing row height in QTreeWidget/QTreeView during edinitg items

    - by serge
    Hi everyone, I have some problems with sizing row's height in QTreeWidget. I use QStyledItemDelegate with QPlainTextEdit. During editing text in QPlainTextEdit i check for changes with a help of: rect = self.blockBoundingRect(self.firstVisibleBlock()) and if text it's height changes i need row in QTreeWidget also resizing. But i don't know how to inform TreeWidget or a Delegate about changes, i even tried to initialize editor with index, that i could use in a future, but it suddenly changes: class MyEditor(QPlainTextEdit): def __init__(self, index = None, parent=None): super(MyEditor, self).__init__(parent) self.index = index self.connect(self, SIGNAL("textChanged()"), self.setHeight) def setHeight(self): if self.index: rect = self.blockBoundingRect(self.firstVisibleBlock()) self.resize(rect.width(), rect.height()) self.emit(SIGNAL("set_height"), QSize(rect.width(), rect.height()), self.index) How can i bound editor's size changes with TreeWidget? And one more thing, by default all items (cells) in TreeWidget have -1 or some big value as default width. I need whole text in cell to be visible, so how can i limit it only by visible range and expand it in height? Thank you in advance, Serge

  • JPG segment length encoding

    - by Blorgbeard
    I'm trying to write some code to extract Exif information from a JPG. Exif is stored in the APP1 segment of a JPG file. According to the Exif spec, the format of the APP1 segment is supposed to start like this: FF E1 // APP1 segment marker nn nn // Length of segment 45 // 'E' 78 // 'x' 69 // 'i' 66 // 'f' And it goes until there is an FF followed by something other than FF or 00. Looking at a JPG in a hex editor, I can see FF E1 and the Exif string, but I'm having trouble decoding the length bytes. An example: In one jpg, my hex editor tells me the APP1 segment is 686 bytes long, but the length bytes are F7 C8. How should I use those bytes to come up with 686 decimal?

  • Adding video and flash functionality to the Ajax Control Toolkit HTMLEditor

    - by Beerdude26
    Greetings, I'm looking for a way to extend the functionality of the HTMLEditor control that the Ajax Control Toolkit supplies for ASP.net. I would like to add video and flash functionality to the editor (buttons, allowed tags, etc). To my knowledge, this is rather easy: plop in an tag with the correct parameters and it just works; I have videos running in the preview window of the editor. Unfortunately, the tag is stripped away when saving the HTML-code and updating it in the database. Hence, I would like to ask if there is any way of adding this functionality apart from manually adding the changes in the source control repository of the Ajax Control Toolkit and recompiling it. If this is not possible, but can offer some help concerning the implementation of this in the source code, it would also be much appreciated. Thank you for your time :)

  • Drag/Drop image url in IE

    - by pierre
    I have a requirement in our web app. to allow users to drag an image from an external site and drop it in a text editor they have open in our app. This is, as you'd expect, to let them embed the image in the document (its a rich text editor). In IE 8 this functionality appears to be broken. If I drag/drop, IE uses a relative URL for the 'src' tag on the image - which means I cannot then download the file and store it since I dont know the full address (eg: '../../imgs/myImage.png') Safari and Firefox do not do this; they provides the fully-qualified address (eg: www.mysite.com/imgs/myImage.png). Is this a bug in IE or just WebKit/Mozilla going the extra mile?

  • .net activeX object

    Hi, I am trying to use my .net image editor user control as an activeX object in a web form. After internet search, I created a asp.net web site from VS2008 and added the following code <object classid="res/ImageEditor.dll#ImageEditor.Editor" height="400" width="400" id="myControl1" name="myControl1" > </object> <INPUT id="Button1" type="button" value="Btn" name="Btn" onclick="return Button1_onclick()"> </script> <script language=javascript> function Button1_onclick() { alert(document.getElementById("myControl1").WatermarkText); } </script> I have two problems 1-) When i first create the project i see the user control on browser but, after rebuilding the user control and changing the dll file at web site, the object no more appears on browser. Instead i see something like an error image. 2-) i can not access public properties. The user control is marked as "make com visible", and register for com is checked at properties.

  • Get the string representation of a jquery DOM object's entire HTML

    - by Scozzard
    Hi, I have had a bit of a look around and am having some difficulty solving a wee issue I am having. I basically have a string of HTML, I convert that to a JQuery DOM object so that I can easily remove all elements that have a certain class using JQuery's .remove(). I.e., var radHtml = editor.get_html(); var jqDom = $(radHtml); $(".thickbox", jqDom).remove(); $(".thickboxcontent", jqDom).remove(); editor.set_html(this.innerHTML); NOTE: The HTML is derived from content in a RADEditor text editor so there are no parent HTML tags, so can look as follows: <p>This is a header</p> <p>this is some content followed by a table </p> <a href="#TB_inline?height=350&amp;width=400&amp;inlineId=myOnPageContent0" class="thickbox">Test Thickbox</a> <div id="myOnPageContent0" class="thickboxcontent"> <table class="modal"> <thead> </thead> <tbody> <tr> <td>item</td> <td>result</td> </tr> <tr> <td>item 1</td> <td>1</td> </tr> <tr> <td>item 2</td> <td>2</td> </tr> <tr> <td>item 3</td> <td>3</td> </tr> </tbody> </table> </div> Here is what the jqDom.html() returns from the HTML above: "This is a header" I was wondering if there was an easy way to do this - have some html and remove all elements (in this case divs) that have a certain class (but leaving their contents). JQuery doesnt have to used, but I would like to. Manipulating the DOM object is fine - it is getting the full DOM object in its entirety as a string that I am having the problem with. Any help would be much appreicated. Thanks.

  • Eclipse plugin: content assist working in Galileo, not Ganymede

    Hi, I am writing a custom editor in a plugin, and I developed it in Galileo. Now I'm trying to run it in Ganymede, but content assist doesn't work. There is no error, just nothing happens when I type "ctrl+space". The way I'm doing it is by providing a custom Configuration class that extends SourceViewerConfiguration, overriding public IContentAssistant getContentAssistant(ISourceViewer sourceViewer). The method gets called when the editor is created but there is no content assist. Was there any change from Ganymede to Galileo that I should be aware of?

  • Doxygen, too heavy to maintain ?

    - by Phong
    I am currently starting using doxygen to document my source code. I have notice that the syntax is very heavy, every time I modify the source code, I also need to change the comment and I really have the impression to pass too much time modifying the comment for every change I make in the source code. Do you have some tips to document my source code efficiently ? Does some editor (or plugin for existing editor) for doxygen to do the following exist? automatically track unsynchronized code/comment and warn the programmer about it. automatically add doxygen comment format (template with parameter name in it for example) in the source code (template) for every new item PS: I am working on a C/C++ project.

  • Wordpress plugin for enhanced WYSIWYG image resizing?

    - by Gnee
    Really, really trying to find a plugin that gives adds functionality to the image-resize functions in Wordpress's WYSIWYG editor. Something where the use of 'Gallery' is not mandatory – just an upload straight from the post editor. In a post, when an image is linked to from another site, there are less options – unlike when an image is uploaded. • You can resize, but it's 100%, 110%, 120%, 130% ....Instead of thumbnail, large, medium, etc, when you upload. •These dimension rarely match the dimensions needed. I know you can type in the W x H in the advanced tab, but my quest to find a better solution is really for the clients using the site. If anyone knows a solution / plugin / modification for this, I'd love to hear it!!

  • PHP: POST Request to ASP.NET website results in 500 server error when html tags included

    - by RyanJD
    My situation: I need to send text to an ASP.NET web service using POST. The entire page there is a form: <form name="aspnetForm" method="post" action="Discussion.aspx?classroom=lG39il1cotOAGJwiNvmQlIPfwmjikD%2fAHLhjjGInAZQ%3d&amp;Page=Posts&amp;ID=794239&amp;Sort=&amp;SortOrder=" id="aspnetForm"> So, I figured if I sent a POST request to this form with the correct inputs it would work. And, to an extent, it has. The form inputs are as follows: <input type="hidden" name="__EVENTTARGET" id="__EVENTTARGET" value="" /> <input type="hidden" name="__EVENTARGUMENT" id="__EVENTARGUMENT" value="" /> <input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="/wEPDw..." /> <input type="hidden" name="__EVENTVALIDATION" id="__EVENTVALIDATION" value="/wEWYQLrt..." /> And a bunch of other inputs. The code I have used is as follows: // grab form info $inputs = extract_form_inputs($discussion['body']); $inputs['__EVENTTARGET'] = 'ctl00$cphMain$ctl01$btnSubmit'; $inputs['ctl00$cphMain$ctl01$tbNickname'] = "Your Instructor"; $inputs['ctl00$cphMain$ctl01$reMessage'] = $message; // submit form $r = request_send($discussion['url'], $inputs); extract_form_inputs does exactly that. $discussion['body'] is the content of the page. $discussion['url'] is the URL of the page. request_send has two arguments: ($url, $post_array). It performs rawurlencode on each element of the array and joins them up as keypairs, in the same way as http_build_query. The request is url encoded properly, sent to the correct page, and works fine until I insert html tags. I have checked - the 'greater than' and 'less than' symbols ('<' and '') are url-encoded properly. However, the server responds with a 500 error. It accepts any other text. Has anyone else come across this sort of problem? Is there some setting on an ASP.NET server that denies html? I can't see this being the case - there is a rich text editor on the website that I am sending requests to. This text editor performs the same request as I am, only I am doing it remotely. The rich text editor sends html to the form - I have checked that, too, using javascript. Note: I do not have the power to modify the ASP.NET server.
