  • How do I make this linkButton custom component work?

    - by Adam
    package { import mx.controls.LinkButton; import flash.text.TextLineMetrics; public class multiLineLinkButton extends LinkButton { override protected function createChildren():void { super.createChildren(); if (textField){ textField.wordWrap = true; textField.multiline = true; } } override public function measureText(s:String):TextLineMetrics { textField.text = s; var lineMetrics:TextLineMetrics = textField.getLineMetrics(0); lineMetrics.width = textField.textWidth; lineMetrics.height = textField.textHeight; return lineMetrics; } } my issue here is if you use this component you will see that the text is bunched up into a very small area. It does not fill the entire width of the linkButton. Anyone know why this is happening?

  • Rails: id field is nil when calling Model.new

    - by Joe Cannatti
    I am a little confused about the auto-increment id field in rails. I have a rails project with a simple schema. When i check the development.sqlite3 I can see that all of my tables have an id field with auto increment. CREATE TABLE "messages" ("id" INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL, "text" text, "created_at" datetime, "updated_at" datetime); but when i call Message.new on the console, the resulting object has an id of nil >> a = Message.new => #<Message id: nil, text: nil, created_at: nil, updated_at: nil> shouldn't the id come back populated?

  • ASP.NET Template Selector/Builder - Dynamic CMS

    - by Ugene
    I am currently building my own CMS for various reasons that could take a long to explain... However i am looking for a dynamic solution to create templates for pages within the CMS and all areas must be editable via the administration area, maybe large text areas broken into multiple areas, text and image area on a page etc. Following on from the above i would like to create the following: Create a new page (selecting a pre-defined template like below) http://img525.imageshack.us/img525/9872/nestedpages.png and then upon editing the page it would have created as many text editors required for each editable region or a file upload control for an image area for example. i am thinking of using nested masterpages for the design elements, just unsure the best-practice way to achieve the above (db structure etc) I somehow hope this provides enough information but are happy to answer any questions you may have. Thanks

  • Firefox DOMParser problem

    - by Michael
    For some reason DOMParser is adding some additional #text elements for each newline \n for this url http://rt.com/Root.rss ...as well as many other RSS I've tried. I checked cnn/bbc feeds, they don't have newlines and dom parser handling them nicely. So I have to add the following before parsing it var xmlText = htmlText.replace(/\n[ ]*/g, ""); var xmlDoc = parser.parseFromString(xmlText, "text/xml"); Server is returning text/xml. var channel = xmlDoc.documentElement.childNodes[0]; this returning \n without my code above and channel with correction.

  • How can I reference only a portion of a TextArea's htmlText block?

    - by Charles Shoults
    I have a number of very poor-quality pdf documents that look like 80's photocopies, which I'm rebuilding in Flash (Flex Builder 3 MXML application), representing paragraphs of text in TextAreas so that selected portions can be bold or italic, or whatever I need. I need a way to apply toolTips or event listeners to individual words within the block of text to link those words to a glossary. I'm perfectly happy to create a definition panel that is populated and made visible with a mouseOver, but don't know how to do it to just a portion of the text. Is there a good / clean / easy way to do this?

  • C#, working with files, "Unauthorized Access"?

    - by Rob
    Hi, I'm learning about opening and saving files with C# and it seems that vista won't let my program save to a file on the root of C:\ , unless I run it in administrator mode. Any ideas how to allow my program to play around with whatever files it wants? Thanks! string name; private void button2_Click(object sender, EventArgs e) ///// OPEN ///// { if (openFileDialog1.ShowDialog() == DialogResult.OK) { name = openFileDialog1.FileName; textBox1.Clear(); textBox1.Text = File.ReadAllText(name); textBox2.Text = name; } } private void button1_Click(object sender, EventArgs e) ///// SAVE ///// { File.WriteAllText(name, textBox1.Text); }

  • Is a web-server (e.g servlets) a good solution for an IM server?

    - by John
    I'm looking at a new app, broadly speaking an IM application with a strong client-server model - all communications go through a server so they can be logged centrally. The server will be Java in some form, clients could at this point be anything from a .NET Desktop app to Flex/Silverlight, to a simple web-interface using JS/AJAX. I had anticipated doing the server using standard J2EE so I get a thread-safe, multi-user server for 'free'... to make things simple let's say using Servlets (but in practice SpringMVC would be likely). This all seemed very neat but I'm concerned if the stateless nature of Servlets is the best approach. If my memory of servlets (been a year or two) is right, each time a client sent a HTTP request, typically a new message entered by the user, the servlet could not assume it had the user/chat in memory and might have to get it from the DB... regardless it has to look it up. Then it either has to use some PUSH system to inform other members of the chat, or cache that there are new messages, for other clients who poll the server using AJAX or similar - and when they poll it again has to lookup the chat, including new messages, and send the new data. I'm wondering if a better system would be the server is running core Java, and implements a socket-based communication with clients. This allows much more immediate data transfer and is more flexible if say the IM client included some game you could play. But then you're writing a custom server and sockets don't sound very friendly to a browser-based client on current browsers. Am I missing some big piece of the puzzle here, it kind of feels like I am? Perhaps a better way to ask the question would simply be "if the client was browser-based using HTML/JS and had to run on IE7+,FF2+ (i.e no HTML5), how would you implement the server?" edit: if you are going to suggest using XMPP, I have been trying to get my head around this in another question, so please consider if that's a more appropriate place to discuss this specifically.

  • How to make a searchable PDF document from a scan AND a source Word document?

    - by Evengard
    Well, I have a scanned PDF with some slightly changes made by hand and a source file. I wish to make a PDF, which would be searchable (based on the text from the source, the changes would remain as they are). I am searching a free (and even better - portable) software which would allow me to somehow "combine" the images from a scan and the text from the source DOC file. So it SEEMS like the image is selectable and searchable.

  • Make jquery array out of div

    - by Industrial
    Hi everyone, Each div with the class "row" is added upon request from the user, to be able to add multiple items at once. So now is the question how I'll collect all the forms in to an array that PHP can read (like JSON for instance). I'll guess that there's already some easy and effective way of doing this? <div class="container"> <div class="row"> <input type="text" name="value1" id="textfield" /> <input type="text" name="value2" id="textfield" /> <input type="text" name="value3" id="textfield" /> </div> </div> Here's what I would like to achieve out of the shown example: array( array ('value1' => '', 'value2' => '', 'value3' => '') ); Thanks!

  • iphone - Connecting to server in background

    - by Satyam svv
    I'm creating an app which connects to server and sends some text. If network (both wifi or 3g) is there, it will immediately send the text to server. But if there is no network, it keeps on polling for server connection every 5 minutes. All this part is working fine. But when using iPhone 4 device, i want the app to check for server connection even when app goes into background. So, when app goes to background and when network comes back, it must be able to send the text to server. How can I achieve it? I've seen some apps where they say that the app will upload photos to server even in background. How will they do it?

  • C# ToolTip will not re-appear after first use.

    - by Roberto Sebestyen
    I have a Forms C# application where I would like to use a toolTip on one of the text boxes. I Initialize the tool-tip in the constructor of the Form class, and it works the first time. So when I hover over the text box with my mouse it works, but once the toolTip times out and it goes away, it does not re-appear when I move my mouse away and back onto the control. I would expect it to come back and I'm wondering what I'm doing wrong. Here is how I initialize the tooltip: myTip = new ToolTip(); myTip.ToolTipIcon = ToolTipIcon.Info; myTip.IsBalloon = true; myTip.ShowAlways = true; myTip.SetToolTip(txtMyTextBox,"My Tooltip Text");

  • A non-ugly way to persist dialog contents across orientation changes?

    - by alex
    So I have a managed AlertDialog with a number of EditTexts & separate portrait + landscape layouts. The user opens the dialog in portrait mode, enters some text and then all of a sudden decides to pop out the keyboard. Now, I need to remove the dialog and recreate it for the changed layout persisting the text entered. What I can think of is getting references to the EdiTexts in onPrepareDialog(..), then getting the actual text in onConfigurationChanged(..), then removing the dialog, then showing it again, then populating it. Rather ugly, huh? Are there any better options?

  • Advantages Of Putting HTML in Javascript

For example having my js file have this $('<div>').addClass('test').append( $('<p>').text('test1'), $('<span>').text('test2'), $('<span>').text('test3') ).insertAfter( $('#test1') ); VS My html file looking like this <div id="#test1"></div> <div class="test"> <p>test1</p> <span>test2</span> <span>test3</span> </div> and the js file have: $('.test').show();

  • Updating label in another form (C#)

    - by cthulhu
    I want to update label of Form1 from Form2. So here's what I have: // Form1 public string Label1 { get { return this.label1.Text; } set { this.label1.Text = value; } } // Form2 private void button1_Click(object sender, EventArgs e) { Form1 frm1 = new Form1(); frm1.Label1 = this.textBox1.Text; this.Close(); } So the above code doesn't work. However, when I add the following: frm1.Show(); after this.Close(); in Form2 code, the Form1 is being opened again (two windows). But I want it to update in the same window so I suggest this.Close() is unnecessary.

  • Regex: How to leave out webding font characters?

    - by DS
    Hi, I've a free text field on my form where the users can type in anything. Some users are pasting text into this field from Word documents with some weird characters that I don't want to go in my DB. (e.g. webding font characters) I'm trying to get a regular expression that would give me only the alphanum and the punctuation characters. But when I try the following, the output is still all the characters. How can I leave them out? <html><body><script type="text/javascript">var str="???????";document.write(str.replace(/[^a-zA-Z 0-9 [:punct]]+/g, " "));</script></body></html>
