  • How do I find everything between two characters after a word using grep, without outputting the entire line?

    - by Nick Sweeting
    I am downlading the info.0.json file from xkcd and trying to parse just the alt text. I don't care if there are quotes around it or not. The problem it that the info.0.json file is all one line, and the alt text is in quotes after the word "alt=". Trying cat info.0.json | grep alt just returns the whole file (because it's all one line). What is the grep or sed code that will get me the alt text?

  • Echo html+php from database

    - by pg-robban
    I am working on a site which deals with a lot of texts in HTML, so recently I learned PHP and moved them into a MySQL database and echo the contents given a specific chapter and section. Now this works relatively fine, the HTML shows up properly. However, in some parts I have included PHP function calls, and these doesn't seem to be evaluated - rather, they get just inserted into the source code (and thus invisible for the page viewer), never doing anything. They did work when they were simple .html files. How can I solve this? For example, a text can look like this: <?php printChapterName(); ?> <p>Some text</p> ... <?php showImage($name, $alt-text); ?> ... This just shows the text on the page. Edit: The functions are echo:ing some HTML.

  • DocumentBuilder.parse() / Parsing Entities

    - by stormin986
    I'm new to parsing XML and am having an issue with entities. (Am doing this on Android, if it makes a difference). Is there a way to have it turn an entity into the character it represents? I have this in the child of an element: "isn&#39;t" (minus quotes). I would prefer it parse it and the end result be a single text node. However, right now this is turned in to TEXT, ENTITY, TEXT. Is there a way to automatically have it parse the entity into text, or a manual way to do it?

  • Some help needed with a SQL query

    - by Psyche
    Hello, I need some help with a MySQL query. I have two tables, one with offers and one with statuses. An offer can has one or more statuses. What I would like to do is get all the offers and their latest status. For each status there's a table field named 'added' which can be used for sorting. I know this can be easily done with two queries, but I need to make it with only one because I also have to apply some filters later in the project. Here's my setup: CREATE TABLE `test`.`offers` ( `id` INT UNSIGNED NOT NULL AUTO_INCREMENT PRIMARY KEY , `client` TEXT NOT NULL , `products` TEXT NOT NULL , `contact` TEXT NOT NULL ) ENGINE = MYISAM ; CREATE TABLE `statuses` ( `id` int(10) unsigned NOT NULL AUTO_INCREMENT, `offer_id` int(11) NOT NULL, `options` text NOT NULL, `deadline` date NOT NULL, `added` datetime NOT NULL, PRIMARY KEY (`id`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1

  • UITextView or UIWebView with normal words looking like links

    - by diwup
    Hey guys, I was looking at the Twitter for iPhone app and was puzzled. First of all, there are normal words looking like links inside. Second, when I touch those link-like words, the text view (or maybe web view) jumps to the corresponding part below (yes, it doesn't open Safari, it just jumps to the text within that text/web view) Now I want to implement the same effects. I should base my implementation on what? UITextView or UIWebView? How to make normal words look like links? How to make those smooth jumps within such a text/web views? Thanks in advance.

  • How access Ajax generated source ?

    - by Rorchackh
    Hello everyone, I created a php file that return dynamically generated text. This text is returned with a div id. When I retrieve that text using Ajax as responseText. I would like to access the properties of that div using javascript, which is impossible since that new text is not added to the DOM. My question is, how can i access that div using either raw javascript or frameworks (am somewhat familiar with jQuery) ? It may be useful to note that the div can be accessed using CSS. Thank you.

  • jquery - How to reference two div elements for a single function?

    - by Ben
    I Have a function that references a specific input text box. I would like to extend the function to be used by two specific input text boxes. Rather than duplicate the code for the other text box, can anyone advise on how to reference the other? Here it uses #Tags, but if i wanted it to reference #Tags2 also, how could I do that? $(function () { $('#Tags').tagSuggest({ separator: ", ", tagContainer: 'div', tags: ["tag1","tag2"] }); });

    private void button2_Click(object sender, EventArgs e) { ChangeLink cl = new ChangeLink(); // Show testDialog as a modal dialog and determine if DialogResult = OK. if (cl.ShowDialog() == DialogResult.OK) { // Read the contents of testDialog's TextBox. // cl.AcceptButton.DialogResult = DialogResult.OK; this.label4.Text = cl.textBox1Text; } else { this.label4.Text = "Cancelled"; } cl.Dispose(); } When i click the button i see the new Form and the textBox1 in the new Form and i can type in the textBox1 something but i dont see anywhere an OK or CANCEL buttons. Should i add them manualy in the new Form designer ? And how to use them then ? This is the code in my new Form what i wanted to do is to type something in the new Form textBox1 and pass the text in the textBox1 to Form1 label4. using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; namespace GatherLinks { public partial class ChangeLink : Form { public ChangeLink() { InitializeComponent(); } public string textBox1Text { get { return textBox1Text = textBox1.Text; } set { } } } } So where are the OK and CANCEL buttons of the Form.ShowDialog ?

  • Painting on GtkScrolledWindow or GtkEventBox

    - by ptomato
    Using GTK, I'm trying to overlay a "More" prompt (but it could just as well be any drawing object) in the corner of a GtkTextView contained within a GtkScrolledWindow. I draw the prompt in the handler for the expose signal of the text view. It works, but when I scroll the window I get artifacts: the prompt is moved along with the contents of the text view and not erased. In order to get rid of the artifacts I trigger a redraw after each scroll. This mostly works, but you can still see the prompt jumping up and down when you scroll quickly. Is there any way to prevent this? It would be nice if the prompt just "floated" on top of the text view. I tried enclosing the scrolled window in a GtkEventBox and painting the prompt on top of that, but that didn't work either; the scrollbars and text view always paint over the prompt, even when you set the event box's window to go in front of its children's windows. UPDATE If I connect the GtkEventBox's expose callback with g_signal_connect_after(), then it is called after the expose callbacks of the GtkScrolledWindow and GtkTextView. The text view still draws over the event box though. I think this is because the scrolling happens asynchronously. Anybody got any idea how I can prevent my drawing from being overwritten?

  • Validation Logic

    - by user2961971
    I am trying to create some validation for a form I have. There are two text boxes and two radio buttons on the form. My logic for this validation I know is a little rusty at the moment so any suggestions would be great. Here is the code for what I have so far: Keep in mind that the int errors is a public variable in the class Start Button code: private void btnStart_Click(object sender, EventArgs e) { errors = validateForm(); //Here I want the user to be able to fix any errors where I am little stuck on that logic at the moment //validate the form while (errors > 0) { validateForm(); errors = validateForm(); } } ValidateForm Method: private int validateForm() { errors = 0; //check the form if there are any unentered values if (txtDest.Text == "") { errors++; } if (txtExt.Text == "") { errors++; } if (validateRadioBtns() == true) { errors++; } return errors; } ValidateRadioBtns Method: private Boolean validateRadioBtns() { //flag - false: selected, true: none selected Boolean blnFlag = false; //both of the radio buttons are unchecked if (radAll.Checked == false && radOther.Checked == false) { blnFlag = true; } //check if there is a value entered in the text box if other is checked else if(radOther.Checked == true && txtExt.Text == "") { blnFlag = true; } return blnFlag; } Overall I feel like this can somehow be more stream lined which I am fairly stuck on. Also, I am stuck on how to ensure the user can return to the form, fix the errors, and then validate again to ensure said errors are fixed. Any suggestions would be greatly appreciated since I know this is such a nooby question.

  • Word Wrap in Vim (preserving indentation)

    - by sixtyfootersdude
    I was just looking at this post which describes how to wrap entire words in vim. The accepted solution was this: :set formatoptions=l :set lbr Which takes this text (tabs are shown as \t): *Inside of window *Outside of window |---------------------------------------| |\t\tthis is a like of text that will wr|ap here |\t\tcan you see the wrap | | | |---------------------------------------| This accomplishes a behavior like this (tabs are shown as \t): *Inside of window *Outside of window |---------------------------------------| |\t\tthis is a like of text that will | |wrap here | |\t\tcan you see the wrap | | | |---------------------------------------| I would however like to redefine this function. I would like the wrapped line to have the same number of tabs in front of it that the line above has plus one. Ie: *Inside of window *Outside of window |---------------------------------------| |\t\tthis is a like of text that will | |\t\t\twrap here | |\t\tcan you see the wrap | | | |---------------------------------------| Any ideas?

  • The *right* JSON content type?

    - by Oli
    Right I've been messing around with JSON for some time, just pushing it out as text and it hasn't hurt anybody (I know of), but I'd like to start doing things properly. I have seen so many purported "standards" for the JSON content type: application/json application/x-javascript text/javascript text/x-javascript text/x-json But which is right? Or best? I gather that there are security and browser support issues varying between them... (I know there's a similar question, What MIME type if JSON is being returned by a REST API?, but I'd like a slightly more targeted answer.)

  • C# WPF Unable to control Textboxes

    - by Bo0m3r
    I'm a beginner in coding into C#. While I'm launching a process I can't controls my textboxes. I found some answers on this forum but the explaination is a bit to difficult for me to implement it for my problem. I created a small program that will run a batch file to make a backup. While the backup is running I can't modify my textboxes, disabling buttons etc... I already saw that this is normal but I don't know how to implement the solutions. My last attempt was with Dispatcher.invoke as you can see below. public partial class MainWindow : Window { public MainWindow() { InitializeComponent(); tb_Status.Text = "Ready"; } public void status() { Dispatcher.Invoke(DispatcherPriority.Send, new Action( () => { tb_Status.Text = "The backup is running!"; } ) ); } public void process() { try { Process p = new Process(); p.StartInfo.WindowStyle = ProcessWindowStyle.Minimized; p.StartInfo.CreateNoWindow = true; p.StartInfo.UseShellExecute = false; p.StartInfo.RedirectStandardOutput = true; p.StartInfo.FileName = "Robocopy.bat"; p.Start(); string output = p.StandardOutput.ReadToEnd(); p.WaitForExit(); tb_Output.Text = File.ReadAllText("Backup\\log.txt"); } catch (Exception ex) { tb_Status.Text = ex.Message.ToString(); } } private void Bt_Start_Click(object sender, EventArgs e) { status(); Directory.CreateDirectory("Backup"); process(); tb_Status.Text = "The backup finished"; File.Delete("Backup\\log.txt"); } } } Any help is appreciated!

  • Displaying Data on the Windows Form

    - by The.Anti.9
    I'm searching files and returning lines that include the search text, and I'm not really sure the best way to display the information I get. Every time I get a match, I want to show, in some sort of control, the File it came from, and the whole text line. (aka streamreader.ReadLine() result). First I tried just putting it all in a read-only text box, but it doesn't have a scroll bar. What is the best form control to help me display this data neatly?
