  • How to resize html canvas element?

    - by russx2
    I have a canvas element defined statically in the html with a width and height. If I attempt to use JavaScript to resize it dynamically (setting a new width and height - either on the attributes of the canvas or via the style properties) I get the following error in Firefox: uncaught exception: [Exception... "Illegal operation on WrappedNative prototype object" nsresult: "0x8057000c (NS_ERROR_XPC_BAD_OP_ON_WN_PROTO)" location: "JS frame :: file:///home/russh/Desktop/test.html :: onclick :: line 1" data: no] Is it possible to resize this element or do I have to destroy it and create a new element on the fly?

  • Extend Javascript Date Object

    - by jAndy
    Hi Folks, I'm curious what would be the best practice to extend the Date constructor. The problem I'm facing is, that the Internet Explorer (< 7+8) can't parse a date like new Date('2010-05-11'); I have to admit that this is not a standard method to parse, anyways FireFox and Chrome perform well on that kind of date string. Now I'm wondering, should I just split/parse/rebuild the string before calling new Date() or is there a more elegant solution ?

  • how to close a child browser in c# or WatiN?

    - by user177060
    I want to close the child window which is of "Browser" type. Have a look at the below code. WatiN.Core.Browser openBrowser = BrowserType.getBrowserObject().attachChildBrowser(document_name + Constants.open_document_title); I want to close the "openBrowser". Close()(available in WatiN) can only be used for the type "IE" of "Firefox" only. So, I cant use Close() method also. Is there any method to close the browser in C# or WatiN?

  • Zend Framework Internet Explorer images won't display

    - by Matt
    I am using Zend Framework and it works fine in Firefox/Safari. In IE I have a problem with images not loading. Say I have an image in my public folder and I have this in my page: <img src="/photos/category/img.jpg" /> Well that works, except when I'm at a URL with a controller like http://www.example.com/controller/action I can see why, but I want a good solution to properly creating these img src links that works across browsers.

  • Default Program With Multiple Versions Installed

    - by Optimal Solutions
    I have multiple versions of Excel installed. Excel 2010, 2007 and 2003. I have them installed on one hard drive with Windows 7 Ultimate as the OS. When I double-click on an XLS file, Excel 2007 opens. I would like Excel 2010 to open. I read and followed the instructions to go to the Control Panel at "Control Panel\All Control Panel Items\Default Programs" and set the default programs. I changed the default to the physical EXE for Excel 2010 at the proper folder that it is installed. When I double-click on the XLS files, Excel 2007 still opens. So I tried to change it to Excel 2003 just to see if it changed to that and it still opens Excel 2007. What am I missing? I would really like the file extension to open Excel 2010, but can not seem to do that.

  • Recovered video files won't play

    - by BioGeek
    I have an SD card with pictures and video which malfunctioned. I was able to recover the files with Photorec. The pictures are OK, but wen I try to open the vide files (*.mov extension) in get the following errors when I try to open them in the following programs Windows Media player: "Windows Media Player encountered a problem while playing the file" Quicktime: "Error -2048: Couldn't open the file because it is not a file that QuickTime understands" VLC: it shows the first frame of the video and the sound is just white noise The filesizes look correct so I presume the data is still in there. Is there any way to fix these recovered video files?

  • Open HTML as XHTML

    - by rybz
    Hi, Having an .html file is it possible to force the browser to treat the contents as XHTML? I mean the file opened from both local or web location. Maybe some on-the-fly convertion or something like that? The background: Firefox and Opera supports natively MathML when the code is embedded in a XHTML file. I need to get a .html file with MathML that would be supported by the mentioned browsers properly. Thank you for any support.

  • IE7 and IE8: Float clearing without adding empty elements

    - by tk-421
    Hello, I'm having a problem similar to the one described here (without a resolution): http://stackoverflow.com/questions/2467745/ie7-float-and-clear-on-the-same-element The following HTML renders as intended in Firefox but not in (both) IE7 and IE8: <html> <head> <style> ul { list-style-type: none; } li { clear: both; padding: 5px; } .left { clear: left; float: left; } .middle { clear: none; float: left; } .right { clear: right; float: left; } </style> </head> <body> <ul> <li>1</li> <li class="left">2</li> <li class="right">3</li> <li class="left">4</li> <li class="middle">5</li> <li class="right">6</li> <li>7</li> </ul> </body> </html> This is a form layout, and in Firefox the results appear like: 1 2 3 4 5 6 7 That's what I'm going for. In IE7 and IE8 however, the results are: 1 2 3 5 6 4 7 [Note: I don't want to float anything to the right because I want the fields on my form to left-align correctly, without a giant space in-between the floated fields to account for the parent container's width.] Apparently I need a full clear, and can probably add an empty list-item element to the list to force clearing, but that seems like a dumb solution and sort of defeats the purpose. Any ideas? I've spent a few hours reading and trying different options without success.

  • Any way to tell apart a CPU defect from a mainboard defect?

    - by Pekka
    I have a fairly modern desktop computer, an AMD Athlon II X2 based silent PC, that does not work. When turned on, it will start physically (all fans are rotating, disks start up...) but not give a signal on any of the graphics ports (DVI, VGA, and HDMI, I tried all three). Also, the reset button does not seem to have any effect. I have stripped the mainboard bare of all SATA connections, extension cards, and the one 2GB RAM chip to eliminate them as the problem source, but to no avail, so I think it's fair to assume it's either the mainboard or the processor that are at fault. However, I have neither a replacement mainboard, nor a replacement processor handy to identify which one is broken. The cause of the defect is unknown, so for all I know, it could be both. Therefore, I'm reluctant to buy replacement hardware blindly before knowing more. Is there any way to further diagnose (or at least get some indication) which component is broken without buying replacement hardware?

  • CSS Doozie: Replacing BG Image on SELECT dropdown

    - by ToiletOverflow
    I need to be able to change the background-image property of a SELECT drop-down using JavaScript/CSS. We have been able to accomplish this in Firefox, but it doesn't appear to be supported at all in IE. From what I've read, IE won't support this. But I'm wondering if there's anything else I could try. Does anyone here have any recommendations?
