  • Javascript one-liners

    - by peoro
    Often I find some really cool javascript one liners that you can copy and paste into your browser address bar in order to get some fancy effects or even useful ones. This, for example, will let you edit anything on the page. javascript:document.body.contentEditable='true'; document.designMode='on'; void 0 What is your favorite? EDIT: I know that technically all these snippets are just javascript scripts that gets evaluated by the browser as if they were defined in the page. I also know that many browsers have got extensions to let you run javascript code (also letting you store scripts somewhere, providing a good editor etc etc). However that's not so practical; I'm not a javascript developer, haven't got firebug installed, and I can't install it anywhere I go. My idea idea is that of collecting the best "mini-scripts" that whoever can just copy and paste in his browser without the need of installing extensions and stuff.

  • View plain text files with different background colors in Mac OSX, for different programming languag

    - by Werner
    Hi, I work with Mac OS X Leopard. I usually have 5 or 10 text files opened at the same time with different programming languages; one for a bash script, another for a python one, etc. When I use exposé all of them look the same, so it is difficult to select them. I wonder how could I work with just plain text files in OSX, so when they are opened in an editor the background color changes or some other thign, so when using exposé it is clear to me which window belongs to what language. I thought about inserting some kind of info to the last line of each document, and then creat some applescript that converts it to RTF or someother text document which includes color in bacjground, so then it is opened with textmate or someother app. Do you know a better approach for this? Thanks

  • How to iterate javascript object properties in the order they were written.

    - by Jenea
    Hi. I identified a bug in my code which I hope to solve with minimal refactoring effort. This bug occurs in Chrome and Opera browsers. Problem: var obj = {23:"AA",12:"BB"}; //iterating through obj's properties for(i in obj) document.write("Key: "+i +" "+"Value: "+obj[i]); Output in FF,IE Key: 23 Value: AA Key: 12 Value: BB Output in Opera and Chrome (Wrong) Key: 12 Value BB Key: 23 Value AA I attempted to make an inverse ordered object like this var obj1={"AA":23,"BB":12}; for(i in obj1) document.write("Key: "+obj[i] +" "+"Value: "+i); However the output is the same. Is there a way to get for all browser the same behaviour with small changes?

  • WPF webbrowser - get HTML downloaded?

    - by Mathias Lykkegaard Lorenzen
    I'm listening to the WPF webbrowser's LoadCompleted event. It has some navigation arguments which provide details regarding the navigation. However, e.Content is always null. Am I paying attention to the wrong event here? How can I fetch the HTML that was just downloaded as string? I tried some things which I would consider hacks, but they return a string of HTML, even though that was not the string downloaded. For instance, with that method when I go to a page which just sends me the string abc, I get the result <document><body>abc</body></document> or something similar. I would prefer not getting into any more hacks than nescessary to get this running.

  • custom domain point to tumblr blog

    - by Julius
    My domain mydomain.com is registered with godaddy. I wish to host my tumblr blog on this domain with nearlyfreespeech.net hosting. My active nameservers at godaddy already point to my authoritative ones at NFS.net which is working. However i'm baffled of the correct configuration to set to point to my Tumblr. Preferably id like (A) my domain http://mydomain.com to host the blog and have http://www.mydomain.com redirect also to http://mydomain.com If this is too difficult my next preference is (B) to have http://www.mydomain.com host the blog whilst http://mydomain.com redirects to http://www.mydomain.com My 3rd preference is to have (C) a sub-domain like http://tumblr.mydomain.com or http://tumblr.mydomain.com to host the blog and i guess have http://mydomain.com and http://www.mydomain.com both redirect to it. I've tried having two aliases mydomain.com and www.mydomain.com pointing to my permanent NFS ip at mydomain.nfshost.com and when i try to add: (1) an A record pointing mydomain.com to the ip 66.6.44.4 as per Tumblr's instructions it tells me i already have the bare domain as an alias so i cant do that. (2) the A record on the www.mydomain.com alias. I can do this with either www.mydomain.com set as an alias or not. But when i tried this with mydomain.com set as the canonical name the result when visiting either mydomain.com or www.mydomain.com was them both continually redirecting to eachother until an error was thrown. So i was wondering if there is a ninja that could save me some hairpulling and tell me the correct way to config A, or else B, or else C.

  • Resize div on browser resize

    - by danit
    I have a <div> which I want to display full screen, but I also need to incorporate a 60px high <div> and a 10px high <div> at the top of the document. The size of the main div will need to re-size as the browser window is re-sized to keep it full screen. <div id="div1" style="height: 60px"> </div> <div id="div2" style="height: 10px"> </div> <div id="fullscreen"> </div> So: fullscreen height = document size - (#div1 + #div2) On re-size recalculate the above value.

  • 64kb limit on the size of MSMQ Multicast Messages

    - by John Breakwell
    When Windows 2003 came out, Microsoft introduced the ability to broadcast messages to any machines that were listening back. All you had to do was send out a message on a particular port and IP address and any client that had set up a Multicast queue with matching port and IP address would get a copy. Since its introduction, there have been a couple of security vulnerabilities that needed to be removed: Microsoft Security Bulletin MS06-052 Vulnerability in Pragmatic General Multicast (PGM) Could Allow Remote Code Execution (919007) Microsoft Security Bulletin MS08-036 Vulnerabilities in Pragmatic General Multicast (PGM) could allow denial of service (950762) The second of these, MS08-036, was resolved through an undocumented change in functionality. Basically, a limit of 64kb was put on the maximum size of a message that could be broadcast using the Multicast method. Obviously this has caused a few problems for any existing MSMQ Multicast applications that expected to be able to send larger messages. A hotfix has been developed to resolve this problem. 961605 FIX: Multicast messages larger than 64 kilobytes (KB) are not delivered as expected by using Message Queuing 3.0 after security update MS08-036 is installed A registry change is required: Open the registry with Regedit Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\RMCAST\Parameters\ Create a DWord called MaxpacketSize Set the value to the desired number of bytes. You can set it to a value between zero and 4MB. If you specify anything above 4MB, it will default to 64K. A reboot is needed after adding this value.

  • In CSS, can "#footer #caption" coexist with "#content # caption"?

    - by Jian Lin
    I was going to "nest" the CSS ids like this #content #caption { color: teal } ... #footer #caption { margin: 2em 1em } because that's the way SASS (a CSS generator) can do nesting for... but then in one HTML document, we cannot have two ids with the same name, isn't that true, so the above nesting won't work or won't work well. (esp if document.getElementById() or $('#caption') or $('caption') is needed to select the element). We can use #content #content_caption { color: teal } ... #footer #footer_caption { margin: 2em 1em } but then why 1 more level of nesting? why not just #content_caption { color: teal } ... #footer_caption { margin: 2em 1em } ?

  • Firefox, prevent rendering between javascript statements.

    - by Erik
    I'm trying to create some kind of zoom around the mouse cursor feature on my website which ultimately runs these two lines (+ the same for height/scrollTop). canvas.style.width = someValue; canvas.parentNode.scrollLeft = someOtherValue; The problem is that in firefox(3.6) the page is re-rendered directly after the first row has been executed and since the view is depending on both values this means that every time i recalculate the view firefox will will render an invalid view before the correct one, in other words creating flicker. I've tried swapping the two rows but get the same problem. In chrome, opera and IE this doesn't happen. Both lines are executed before any rendering is done. Is there any way to lock the rendering manually, maybe something like this? document.disableRendering(); //fantasy function canvas.style.width = someValue; canvas.parentNode.scrollLeft = someOtherValue; document.enableRendering(); //fantasy function

  • IHTMLTxtRange.execCommand("Copy",false,null) fails due to IE settings

    - by srirambalaji-s
    We have a .Net application that is used for editing/rendering customized HTML documents. It is hosted in IE using the AxSHDocVw.AxWebBrowser controls. We proceed with navigating to "about:blank" page initially then we change the Document by writing our custom values into it. The problem we are facing is the call to IHTMLTxtRange.execCommand("Copy",false,null) is failing if we don't enable the IE Security Settings in the Internet Security zone (Scripting-Allow Programmatic Access to Clipboard ). In order to bypass the security setting ,I tried to point to a local html file initially while navigating. But this fails as soon as I modify the Document. I want to use the IHTMLTxtRange.execCommand("Copy",false,null) command so that I can customize our Copy/Paste operations. Is there any other way I can do this. Please share your ideas inorder to overcome this situation. Thanks. Sriram

  • OpenXml - How to identify whether the paragraph extends to next page

    - by K.V.
    From aspx page, I dynamically add paragraphs to a word document using OpenXml SDK. In this case, a page break within a paragraph is not allowed. So in case a paragraph starts in middle of page 1 and extends to page2 then it should actually start in Page2. However, if it ends in the same page it is okay. How to achieve this? Is there a way to set in th document that page break is not allowed within a paragraph? Any input is highly appreciated.

  • Problem Passing Variable to Submit Form in Firefox

    In the following example, I have a link that sends a variable to a function which checks if the variable is true and, if so, submits a form on the page. This has been tested and works in IE, Safari, and Chrome, but not Firefox. Trying to figure out what's wrong in Firefox. The function which checks 'action' and then submits form 'login' : function submit(action) { if (action == "submit") { document.login.submit(); } } Link to pass action variable and submit form: <a href="javascript:submit('submit');">SEND FORM</a> When I remove the check and just have the following, it works fine in Firefox: function submit() { document.login.submit(); } <a href="javascript:submit();">SEND FORM</a>

  • Why does order matter for ImageMagick's -colorspace operation?

    - by Mark Trapp
    Starting with ImageMagick 6, the command style changed to solve a bunch of problems outlined in the Basic Usage document. That document does imply that for simple operations, one should only need to move the options from before the source file to between the source and output files to convert from the "old" style to the "new" style. However, this doesn't seem to work for the -colorspace operation. When I use the following command, I get an output file with the correct colors: convert -colorspace rgb input.pdf output.png But when I try to use the new command style, the -colorspace operation is never applied: convert input.pdf -colorspace rgb output.png Samples: Why does this occur?

  • Decoupling into DAL and BLL - my concerns.

    - by novice_man
    Hi, In many posts concerning this topic I come across very simple examples that do not answer my question. Let's say a have a document table and user table. In DAL written in ADO.NET i have a method to retries all documents for some criteria. Now I the UI I have a case where I need to show this list along with the names of the creator. Up to know I have it done with one method in DAL containig JOIN statement. However eveytime I have such a complex method i have to do custom mapping to some object that doesn't mark 1:1 to DB. Should it be put into another layer ? If so then I will have to resing from join query for iteration through results and querying each document author. . . which doen't make sense... (performance) what is the best approach for such scenarios ?

  • What are the advantages to use StringBuilder versus XmlDocument or related to create XML documetns?

    - by Rob
    This might be a bit of a code smell, but I have seen it is some production code, namely the use of StringBuilder as opposed to XmlDocument when creating XML documents. In some cases these are write once operations (e.g. create the document and save it to disk) where as others are passing the built string to an XmlDocument to preform an XslTransform to a document that is returned to the client. So obvious question: is there merit to doing things this way, is it something that should be done on a case-by-case basis, or is this the wrong way of doing things?

  • OpenGL Application displays only 1 frame

    - by Avi
    EDIT: I have verified that the problem is not the VBO class or the vertex array class, but rather something else. I have a problem where my vertex buffer class works the first time its called, but displays nothing any other time its called. I don't know why this is, and it's also the same in my vertex array class. I'm calling the functions in this order to set up the buffers: enable client states bind buffers set buffer / array data unbind buffers disable client states Then in the draw function, that's called every frame: enable client states bind buffers set pointers unbind buffers bind index buffer draw elements unbind index buffer disable client states Is there something wrong with the order in which I'm calling the functions, or is it a more specific code error? EDIT: here's some of the code Code for setting pointers: //element is the vertex attribute being drawn (e.g. normals, colors, etc.) static void makeElementPointer(VertexBufferElements::VBOElement element, Shader *shade, void *elementLocation) { //elementLocation is BUFFER_OFFSET(n) if a buffer is bound switch (element) { .... glVertexPointer(3, GL_FLOAT, 0, elementLocation); //changes based on element .... //but I'm only dealing with } //vertices for now } And that's basically all the code that isn't just a straight OpenGL function call.
