  • Process.Start concatenating cmd line from previous invocation

    - by Ralph
    Hi, I am using a Process.Start in .Net 2.0 to start a child win32 app. Process.start ( "SomeProcess.exe", "<Cmd line>" ); The process runs fine but and the user then closes this window. However if I then run the same process again in the same session, the cmd line recieved by the called process is now a concatentation of the previous call. I.e SomeProcess.exe recieves the cmd line " SomeProcess.exe ". Has anyone else seen this behaviour before? Any help much appreciated. Ralph.

  • MVC Html.textbox/dropdown/whatever won't refresh on postback

    - by Cynthia
    OK, let's start with the Html.Textbox. It is supposed to contain text read from a file. The file read is based on what the user picks from a dropdown list. The first time it is fine. The user picks a value from the dropdown list. The controller uses that value to read some text from a file, and returns that text to the view via the view model. Everything is fine. THen the user picks another value from the dropdown list. The controller reads a new value from a file and returns it via the view model. Debugging to the LINE BEFORE THE HTML.TEXTBOX is set in the view shows that the model contains the correct value. However, the textbox itself still shows the PREVIOUS value when the page displays! If I switch from Html.Textbox to a plain input, type="text" html control, everything works fine. That's not so hard, but the same thing happens with my dropdown list -- I can't set the selected value in code. It always reverts to whatever was chosen last. Rendering a "select" tag with a dynamically-generated option list is a pain. I would love to be able to use Html.Dropdown. What am I missing here?? This is such a simple thing in webforms!

  • HTML.CheckBox persisting state after POST - Refresh ModelState?

    - by Kirschstein
    I have a form that's made up of many items (think order items on an amazon order). Each row has a checkbox associated with them so the user can select many items and click 'remove'. The form is built up a bit like this; <% for (int i = 0; i < Model.OrderItems.Count; i++) { %> <tr> <td><%= Html.Hidden(String.Format("OrderItems[{0}].Id", i), Model.OrderItems[i].Id)%> <%= Html.CheckBox(String.Format("OrderItems[{0}].Checked", i), Model.OrderItems[i].Checked)%></td> <td><%= Html.TextBox(String.Format("OrderItems[{0}].Name", i), Model.OrderItems[i].Name)%></td> <td><%= Html.TextBox(String.Format("OrderItems[{0}].Cost", i), Model.OrderItems[i].Cost)%></td> <td><%= Html.TextBox(String.Format("OrderItems[{0}].Quantity", i), Model.OrderItems[i].Quantity)%></td> </tr> <% } %> The model binder does its magic just fine and the list is correctly populated. However, after I process the request in the action (e.g. remove the appropriate items) and return a new view containing fewer items, the state of the form is 'semi' persisted. Some check boxes remain checked, even though in the edit model all the bools are set to false. I don't have this problem if I return a RedirectToActionResult, but using that as a solution seems a bit of a hacky work around. I think I need to flush/refresh the ModelState, or something similiar, but I'm unsure of the terms to search for to find out how.

  • ASP.Net UpdatePanel, want to have html-tag as a parameter

    - by Nordis
    This is my problem, I have one textbox, one button and one label. Everything is inside an updatepanel. Let's say I want to test if a valid html-tag is entered in the textbox when I press the button. In the code-behind I have a method for that. Everythings works just fine, except when I actually enter a html-tag in my textbox. If I test < html, it works. But not if I test . So my question is, doesn't the updatepanel accept html-tags as parameters? Because my breakpoint for the button_click doesn't triggers. Sorry for my bad english.. :)

  • Specify Action on sub-controller when using Html.RenderAction

    - by iammaz
    I have a UserControl that I call with Html.RenderAction(...), so far so good.. Then I want to specify in the user control, which action should be used Html.BeginForm("DeleteComment", "Comments", new { Id = "frmDelete" }, FormMethod.Post);%> <%= Html.SubmitImage( "imgbtnDelete", "/image.png", new { ... })%> <% Html.EndForm(); %> And therein lies my problem; this calls the user control's controller/action. What I want to happen is to call the pages action first and then be able to specify what action to call on the user control's controller. Is this possible?? Thanks from an MVC noob

  • 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.

  • Logrotate not doing any rotation

    - by blizz
    I just set up LogRotate on my RHEL6 server so that it rotates my custom Apache log files. However, it doesn't do anything when i try manually running it.

  • Calling CONTENT_SCRIPT JS From BROWSER_ACTION Popup HTML

    - by Aristotle
    I'm working on a Google Chrome Extension and would like to get an HTML from within my popup HTML to call functions within my loaded javascript file. My manifest follows: { "name": "Extension", "version": "1.0", "description": "Extension", "browser_action": { "default_icon": "icon.png", "default_title": "Ext", "popup": "popup.html" }, "content_scripts": [{ "matches": ["http://*/*"], "css": ["ext.css"], "js": ["jquery.js","scripts.js"] }], "permissions": [ "http://*/*" ] } As you can see I'm loading in a local copy of jQuery, along with another javascript file for my own personal logic. My popup document looks like this: <select id="values"> <option>Foo</option> <option>Bar</option> </select> And the contents of my scripts.js file follow: $(function(){ $("#values").change(function(){ alert("Foo"); }); }); This isn't doing what I expect though - alerting "Foo" anytime I change a value in my popup HTML. How can I get these two files to communicate with eachother? Or can they at all?

  • Reconstructing Position in the Original Array from the Position in a Stripped Down Array

    - by aronchick
    I have a text file that contains a number of the following: <ID> <Time 1> --> <Time 2> <Quote (potentially multiple line> <New Line Separator> <ID> <Time 1> --> <Time 2> <Quote (potentially multiple line> <New Line Separator> <ID> <Time 1> --> <Time 2> <Quote (potentially multiple line> <New Line Separator> I have a very simple regex for stripping these out into a constant block so it's just: <Quote> <Quote> <Quote> What I'd like to do is present the quotes as a block to the user, and have them select it (using jQuery.fieldSelection) and then use the selected content to back out to the original array, so I can get timing and IDs. Because this has to go out to HTML, and the user has to be able to select the text on the screen, I can't do anything like hidden divs or hidden input fields. The only data I will have is the character range selected on screen. To be specific, this is what it looks like: 1 0:00 --> 0:05 He was bored. So bored. His great intellect, seemingly inexhaustible, was hungry for new challenges but he was the last of the great innovators 2 0:05 --> 0:10 - society's problems had all been solved. 3 0:11 --> 0:20 All seemingly unconnected disciplines had long since been found to be related in horrifically elusive and contrived ways and he had mastered them all. And this is what I'd like to present to the user for selection: He was bored. So bored. His great intellect, seemingly inexhaustible, was hungry for new challenges but he was the last of the great innovators - society's problems had all been solved. All seemingly unconnected disciplines had long since been found to be related in horrifically elusive and contrived ways and he had mastered them all. Has anyone com across something like this before? Any ideas how to take the selected text, or selection position, and go backwards to the original meta-data?

    Hi, I would like to render specific HTML snippets for displaying banners, because each banner has a different nature (some images, some flash, etc). Every banner file is under app/public/banners/. I tried many ways, like: render :file => "/banners/somebanner.html" But it can't locate the file, because rails looks under app/views. Any Ideas ?

  • Textbox autofill not in correct position in safari

    - by jerjer
    Hello All, Has anyone experience this weird issue on safari? Textbox autofill is not at its correct position, please see screenshot below. I have been searching for answers in google for almost a day, still no luck. This is the built-in autofill feature of safari. Here is the markup: index.php <html> <body> <div id="nav"></div> <div id="content"> <iframe style="width:100%;height:100%" src="add_user.php" frameborder="0"></iframe> </div> .... </body> </html> add_user.php <html> .... <body> <form method="post"> <h3>Add User (Admin only) <div id="msg">Please enter First and Last Name.</div> <ul> <li><label>* Email</label> <input type="text" id="email" /></li> <li><label>* First Name</label> <input type="text" id="fname" /></li> <li><label>* Last Name</label> <input type="text" id="lname" /></li> .... </ul> </form> </body> </html> I am suspecting that this is caused by the iframe, but it works just fine in other browsers. Also I could not change the page design(using iframe) right away for practical reasons. Thanks

  • PHP Simple DOM Parser

    - by Junior Coder
    Hi guys I'm using this wonderful class here to do a bit of code embed filtering: http://simplehtmldom.sourceforge.net/. It extends the PHP DOM document class. Pretty much what I am doing is parsing a string through this class that contains embed code, i grab the unique bits of information eg id, width, height send through a handler function which inserts the id, width, height etc into my predefined "safe" template and reinsert my safe template in the place of the embed code the user has put in. May seem a backward way of doing it but it's the way it has to be done :) All of that works fine. Problem is when there is more than just embed code contained in the string, as I can't just replace the embed code i can only replace the entire string which wipes the rest of the tags etc string. For example if there were a p tag that would be wiped. So my question is how using this class can i just replace the certain part of the string? Spent the last few days trying to work this out and need some more input. It appears the class can do this so i'm stumped. Here's a basic version of what i have so far :) // load the class $html = new simple_html_dom(); // load the entire string containing everything user entered here $return = $html->load($string); // check for embed tags if($html->find('embed') == true { foreach($html->find('embed') as $element) { // send it off to the function which returns a new safe embed code $element = create_new_embed($parameters); // this is where i somehow i need to save the changes and send it back to $return } } Any input would be gratefully appreciated. If i have explained my problem well enough please let me know :)

Installation process went like below: root@aserver [OOO330_m20_native_packed-1_en-US.9567/RPMS]# rpm -i *.rpm package openoffice.org-ure-1.7.0-9567.i586 is already installed package ooobasis3.3-core01-3.3.0-9567.i586 is already installed package ooobasis3.3-en-US-3.3.0-9567.i586 is already installed package ooobasis3.3-core02-3.3.0-9567.i586 is already installed package ooobasis3.3-core03-3.3.0-9567.i586 is already installed package ooobasis3.3-core04-3.3.0-9567.i586 is already installed package ooobasis3.3-core05-3.3.0-9567.i586 is already installed package ooobasis3.3-core06-3.3.0-9567.i586 is already installed package ooobasis3.3-core07-3.3.0-9567.i586 is already installed package ooobasis3.3-en-US-base-3.3.0-9567.i586 is already installed package ooobasis3.3-en-US-calc-3.3.0-9567.i586 is already installed package ooobasis3.3-en-US-draw-3.3.0-9567.i586 is already installed package ooobasis3.3-en-US-help-3.3.0-9567.i586 is already installed package ooobasis3.3-en-US-impress-3.3.0-9567.i586 is already installed package ooobasis3.3-en-US-math-3.3.0-9567.i586 is already installed package ooobasis3.3-en-US-res-3.3.0-9567.i586 is already installed package ooobasis3.3-en-US-writer-3.3.0-9567.i586 is already installed package ooobasis3.3-base-3.3.0-9567.i586 is already installed package ooobasis3.3-calc-3.3.0-9567.i586 is already installed package ooobasis3.3-draw-3.3.0-9567.i586 is already installed package ooobasis3.3-images-3.3.0-9567.i586 is already installed package openoffice.org3-3.3.0-9567.i586 is already installed package ooobasis3.3-impress-3.3.0-9567.i586 is already installed package ooobasis3.3-math-3.3.0-9567.i586 is already installed package ooobasis3.3-writer-3.3.0-9567.i586 is already installed package jre-1.6.0_22-fcs.i586 is already installed package ooobasis3.3-binfilter-3.3.0-9567.i586 is already installed package ooobasis3.3-en-US-binfilter-3.3.0-9567.i586 is already installed package ooobasis3.3-gnome-integration-3.3.0-9567.i586 is already installed package ooobasis3.3-graphicfilter-3.3.0-9567.i586 is already installed package ooobasis3.3-javafilter-3.3.0-9567.i586 is already installed package ooobasis3.3-kde-integration-3.3.0-9567.i586 is already installed package ooobasis3.3-onlineupdate-3.3.0-9567.i586 is already installed package ooobasis3.3-ooofonts-3.3.0-9567.i586 is already installed package ooobasis3.3-oooimprovement-3.3.0-9567.i586 is already installed package ooobasis3.3-ooolinguistic-3.3.0-9567.i586 is already installed package ooobasis3.3-pyuno-3.3.0-9567.i586 is already installed package ooobasis3.3-testtool-3.3.0-9567.i586 is already installed package ooobasis3.3-xsltfilter-3.3.0-9567.i586 is already installed package openoffice.org3-base-3.3.0-9567.i586 is already installed package openoffice.org3-calc-3.3.0-9567.i586 is already installed package openoffice.org3-dict-en-3.3.0-9567.i586 is already installed package openoffice.org3-dict-es-3.3.0-9567.i586 is already installed package openoffice.org3-dict-fr-3.3.0-9567.i586 is already installed package openoffice.org3-draw-3.3.0-9567.i586 is already installed package openoffice.org3-en-US-3.3.0-9567.i586 is already installed package openoffice.org3-impress-3.3.0-9567.i586 is already installed package openoffice.org3-math-3.3.0-9567.i586 is already installed package openoffice.org3-writer-3.3.0-9567.i586 is already installed root@aserver [OOO330_m20_native_p acked-1_en-US.9567/RPMS]# soffice bash: soffice: command not found

  • Regex and PHP for extracting contents between tags with several line breaks

    - by John
    How can I extract the content between tags with several line breaks? I'm a newbie to regex, who would like to know how to handle unknown numbers of line break to match my query. Task: Extract content between <div class="test"> and the first closing </div> tag. Original source: <div class="test">optional text<br/> content<br/> <br/> content<br/> ... content<br/><a href="/url/">Hyperlink</a></div></div></div> I've worked out the below regex, /<div class=\"test\">(.*?)<br\/>(.*?)<\/div>/ Just wonder how to match several line breaks using regex. There is DOM for us but I am not familiar with that.

  • How to change line thickness in iText?

    - by drasto
    I'm drawing images to pdf using Java framework iText. I need to draw lines of specified width. There is a method setLineWidth(float width) in class PdfContentByte that should change it. However no matter what value I pass as its parameter the lines drawn are always extra thin. There is following line in javadoc of setLineWidth: The line width specifies the thickness of the line used to stroke a path and is measured in user space units. I don't know what is "space unit". Everything else in iText seems to be measured in point(around 1/72 inch). I cant find any reference to what are those "space units" and how to change them. code: to.setLineWidth(thickness); to.moveTo(x, y); to.lineTo(x + 100, y + 100); Variable to contains instance of PdfContentByte.

  • Drawing triangle/arrow on a line with CGContext

    - by Pete
    Hi, I am using the framework of route-me for working with locations. In this code the path between two markers(points) will be drawn as a line. My Question: "What code should I add if I want to add an arrow in the middle(or top) of the line, so that it points the direction" Thanks - (void)drawInContext:(CGContextRef)theContext { renderedScale = [contents metersPerPixel]; float scale = 1.0f / [contents metersPerPixel]; float scaledLineWidth = lineWidth; if(!scaleLineWidth) { scaledLineWidth *= renderedScale; } //NSLog(@"line width = %f, content scale = %f", scaledLineWidth, renderedScale); CGContextScaleCTM(theContext, scale, scale); CGContextBeginPath(theContext); CGContextAddPath(theContext, path); CGContextSetLineWidth(theContext, scaledLineWidth); CGContextSetStrokeColorWithColor(theContext, [lineColor CGColor]); CGContextSetFillColorWithColor(theContext, [fillColor CGColor]); // according to Apple's documentation, DrawPath closes the path if it's a filled style, so a call to ClosePath isn't necessary CGContextDrawPath(theContext, drawingMode); }

  • How can I store HTML in a Doctrine YML fixture

    - by argibson
    I am working with a CMS-type site in Symfony 1.4 (Doctrine 1.2) and one of the things that is frustrating me is not being able to store HTML pages in YML fixtures. Instead I have to create SQL backups of the data if I want to drop and rebuild which is a bit of a pest when Symfony/Doctrine has a fantastic mechanism for doing exactly this. I could write a mechanism that reads in a set of HTML files for each page and fills the data in that way (or even write it as a task). But before I go down that road I am wondering if there is any way for HTML to be stored in a YML fixture so that Doctrine can simply import it into the database. Update: I have tried using symfony doctrine:data-dump and symfony doctrine:data-load however despite the dump correctly creating the fixture with the HTML, the load task appears to 'skip' the value of the column with the HTML and enters everything else into the row. In the database the field doesn't show up as 'NULL' but rather empty so I believe Doctrine is adding the value of the column as ''. Below is a sample of the YML fixture that symfony doctrine:data-dump created. I have tried running symfony doctrine:data-load against various forms of this including removing all the escaped characters (new lines and quotes leaving only angle brackets) but it still doesn't work. Product_69: name: 'My Product' Developer: Developer_30 tagline: 'Text that briefly describes the product' version: '2008' first_published: '' price_code: A79 summary: '' box_image: '' description: "<div id=\"featureSlider\">\n <ul class=\"slider\">\n <li class=\"sliderItem\" title=\"Summary\">\n <div class=\"feature\">\n Some text goes in here</div>\n </li>\n </ul>\n </div>\n" is_visible: true
