  • Internet Access in Ubuntu on VirtualBox

    - by Joel Martinez
    I recently installed Ubuntu on a VirtualBox VM ... it installed just fine (much easier than on VirtualPC). However, I'm unable to get internet access from the guest OS (ie. Ubuntu). Can anyone give me any pointers on how I might enable this? The Host OS is Windows Vista, and the hardware is an IBM Lenovo. Thanks! :-)

  • If as assert fails, is there a bug?

    - by RichAmberale
    I've always followed the logic: if assert fails, then there is a bug. Root cause could either be: Assert itself is invalid (bug) There is a programming error (bug) (no other options) I.E. Are there any other conclusions one could come to? Are there cases where an assert would fail and there is no bug?

  • How to avoid keyboard hide & show when focus changes from UITextField and UIWebView?

    - by Manoj
    I have a requirement in which the view contains one native UITextField and one UIWebView. The issue is if I switch the focus from UITextView to UIWebView, the keyboard window flicker(hides and then shows). ie, I got UIKeyboardWillHideNotification and UIKeyboardDidShowNotification But, this is not happening when I switch the other way. ies, I got only UIKeyboardDidShowNotification Is there any way to avoid this flickering effect? Note: I also notices if I have multiple UITextField and UIWebView, this issue is not happening with the same type of views.

  • Why is FLD1 loading NaN instead?

    - by Bernd Jendrissek
    I have a one-liner C function that is just return value * pow(1.+rate, -delay); - it discounts a future value to a present value. The interesting part of the disassembly is 0x080555b9 : neg %eax 0x080555bb : push %eax 0x080555bc : fildl (%esp) 0x080555bf : lea 0x4(%esp),%esp 0x080555c3 : fldl 0xfffffff0(%ebp) 0x080555c6 : fld1 0x080555c8 : faddp %st,%st(1) 0x080555ca : fxch %st(1) 0x080555cc : fstpl 0x8(%esp) 0x080555d0 : fstpl (%esp) 0x080555d3 : call 0x8051ce0 0x080555d8 : fmull 0xfffffff8(%ebp) While single-stepping through this function, gdb says (rate is 0.02, delay is 2; you can see them on the stack): (gdb) si 0x080555c6 30 return value * pow(1.+rate, -delay); (gdb) info float R7: Valid 0x4004a6c28f5c28f5c000 +41.68999999999999773 R6: Valid 0x4004e15c28f5c28f6000 +56.34000000000000341 R5: Valid 0x4004dceb851eb851e800 +55.22999999999999687 R4: Valid 0xc0008000000000000000 -2 =R3: Valid 0x3ff9a3d70a3d70a3d800 +0.02000000000000000042 R2: Valid 0x4004ff147ae147ae1800 +63.77000000000000313 R1: Valid 0x4004e17ae147ae147800 +56.36999999999999744 R0: Valid 0x4004efb851eb851eb800 +59.92999999999999972 Status Word: 0x1861 IE PE SF TOP: 3 Control Word: 0x037f IM DM ZM OM UM PM PC: Extended Precision (64-bits) RC: Round to nearest Tag Word: 0x0000 Instruction Pointer: 0x73:0x080555c3 Operand Pointer: 0x7b:0xbff41d78 Opcode: 0xdd45 And after the fld1: (gdb) si 0x080555c8 30 return value * pow(1.+rate, -delay); (gdb) info float R7: Valid 0x4004a6c28f5c28f5c000 +41.68999999999999773 R6: Valid 0x4004e15c28f5c28f6000 +56.34000000000000341 R5: Valid 0x4004dceb851eb851e800 +55.22999999999999687 R4: Valid 0xc0008000000000000000 -2 R3: Valid 0x3ff9a3d70a3d70a3d800 +0.02000000000000000042 =R2: Special 0xffffc000000000000000 Real Indefinite (QNaN) R1: Valid 0x4004e17ae147ae147800 +56.36999999999999744 R0: Valid 0x4004efb851eb851eb800 +59.92999999999999972 Status Word: 0x1261 IE PE SF C1 TOP: 2 Control Word: 0x037f IM DM ZM OM UM PM PC: Extended Precision (64-bits) RC: Round to nearest Tag Word: 0x0020 Instruction Pointer: 0x73:0x080555c6 Operand Pointer: 0x7b:0xbff41d78 Opcode: 0xd9e8 After this, everything goes to hell. Things get grossly over or undervalued, so even if there were no other bugs in my freeciv AI attempt, it would choose all the wrong strategies. Like sending the whole army to the arctic. (Sigh, if only I were getting that far.) I must be missing something obvious, or getting blinded by something, because I can't believe that fld1 should ever possibly fail. Even less that it should fail only after a handful of passes through this function. On earlier passes the FPU correctly loads 1 into ST(0). The bytes at 0x080555c6 definitely encode fld1 - checked with x/... on the running process. What gives?

    window.popup = window.open($(this).attr('href'), 'Ad', 'left=20,top=20,width=500,height=500,toolbar=1,resizable=0'); $(window.popup).onload = function() { alert("Popup has loaded a page"); }; This doesn't work in any browser I've tried it with (IE, Firefox, Chrome). How can I detect when a page is loaded in the window (like an iframe onload)?

  • jquery cycle not working/playing in IE7

    - by user202141
    got the jq cycle plugin to work nicely on all the other major browsers, but IE7 just shows the first nested element (an img with a anchor wrapped around it) with no fade/animation. http://alitedesigns.com/ I checked for trailing commas after the custom attributes for cycle, any thoughts on why IE won't play nice? thanks!

  • jQuery plugin to wrap text around images + support IE6

    - by Alex
    This is a tall order, but is there a jQuery or Mootools (or other framework) plugin to wrap text around images and support IE6? I've tried the jQSlickWrap, but unless the browser supports HTML 5, you're out of luck. What's strange is that IE 6 supports the jQuery Background Canvas plugin, which uses the CANVAS object (via excanvas.js) just as this plugin does. Thanks.

  • ASP.net canvas server control

    - by Pierreten
    I was wondering if anyone has come up with an ASP.net server tag for the HTML5 canvas? I was thinking of something where I could declaritively define paths, curves; etc in the aspx markup, and the control would deliver the js to do this (perhaps with support for browser detection, and delivery of an emulation script for IE browsers.) Maybe a good idea for a Codeplex project for me to start up?

  • intercepting http traffic to/from Google Chrome

    - by anjanb
    I use Fiddler for intercepting HTTP traffic when using IE or Firefox. Now that I'm using chrome for most of my day, I would like to be able to see the http traffic using something like Fiddler. What do chrome developers use ? I prefer something automatic like Fiddler but something that needs config, etc would also help. P.S : I'm on windows vista 64-bit HOME PREMIUM, if that's important.

  • jQuery Validator's "required" not working when value is set at statup

    - by nandrew
    Hello, I have a problem with jQuery Validator. I want to use "required" property on a text input. It doesn't work when input has set value attribute by HTML code (tested on Firefox (3.5), and on IE 8 - on IE it works a bit better). Story: 1. Page loads; 2. value is cleared; 3. focus is changed. 4. Nothing happens but the error message should be displayed; 5. getting back to the field and typing some characters. 6. changing focus; 7. getting back to the field; 8. clearing the field. 9. Error is displayed even before leaving the field. The HTML code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head> <script src="Web/Scripts/jquery-1.3.2.min.js" type="text/javascript"></script> <script src="Web/Scripts/jquery.validate.js" type="text/javascript"></script> </head> <body> <form id="form1"> <input type="text" id="name1" name="name1" value="test" /><br /> <input type="text" /> </form> <script type="text/javascript"> $(document).ready(function() { var validator = $("form").validate({ rules: { name1: { required: true, minlength: 2 } }, messages: { name1: "bad name" }, }); }); </script> </body> </html>

  • Schema to support dynamic properties

    - by Johan Fredrik Varen
    Hi people. I'm working on an editor that enables its users to create "object" definitions in real-time. A definition can contain zero or more properties. A property has a name a type. Once a definition is created, a user can create an object of that definition and set the property values of that object. So by the click of a mouse-button, the user should ie. be able to create a new definition called "Bicycle", and add the property "Size" of type "Numeric". Then another property called "Name" of type "Text", and then another property called "Price" of type "Numeric". Once that is done, the user should be able to create a couple of "Bicycle" objects and fill in the "Name" and "Price" property values of each bike. Now, I've seen this feature in several software products, so it must be a well-known concept. My problem started when I sat down and tried to come up with a DB schema to support this data structure, because I want the property values to be stored using the appropriate column types. Ie. a numeric property value is stored as, say, an INT in the database, and a textual property value is stored as VARCHAR. First, I need a table that will hold all my object definitions: Table obj_defs id | name | ---------------- 1 | "Bicycle" | 2 | "Book" | Then I need a table for holding what sort of properties each object definition should have: Table prop_defs id | obj_def_id | name | type | ------------------------------------ 1 | 1 | "Size" | ? | 2 | 1 | "Name" | ? | 3 | 1 | "Price" | ? | 4 | 2 | "Title" | ? | 5 | 2 | "Author" | ? | 6 | 2 | "ISBN" | ? | I would also need a table that holds each object: Table objects id | created | updated | ------------------------------ 1 | 2011-05-14 | 2011-06-15 | 2 | 2011-05-14 | 2011-06-15 | 3 | 2011-05-14 | 2011-06-15 | Finally, I need a table that will hold the actual property values of each object, and one solution is for this table to have one column for each possible value type, such as this: Table prop_vals id | prop_def_id | object_id | numeric | textual | boolean | ------------------------------------------------------------ 1 | 1 | 1 | 27 | | | 2 | 2 | 1 | | "Trek" | | 3 | 3 | 1 | 1249 | | | 4 | 1 | 2 | 26 | | | 5 | 2 | 2 | | "GT" | | 6 | 3 | 2 | 159 | | | 7 | 4 | 3 | | "It" | | 8 | 5 | 3 | | "King" | | 9 | 6 | 4 | 9 | | | If I implemented this schema, what would the "type" column of the prop_defs table hold? Integers that each map to a column name, varchars that simply hold the column name? Any other possibilities? Would a stored procedure help me out here in some way? And what would the SQL for fetching the "name" property of object 2 look like?

  • Grading your programming ability?

    - by Farstucker
    I understand this is a subjective question and very likely could be closed, and although there is no right or wrong answer I do believe its a legitimate question. At what point do you no longer consider someone a beginner (ie knowledge of loops, encapsulation, instantiation), an intermediate (design patterns, reflection, delegates, interfaces) or an expert (architecture, multi-threadding). My rational for asking such a question is two-fold, first, when do I stop labeling my questions as beginner and during a job interview how should I categorize myself?

  • Keep div:hover open when changing nested select box

    - by JMC Creative
    This is an IE-only problem. .toolTip becomes visible when it's parent element is :hovered over. Inside of .toolTip is a select box. When the user opens the select box to make a selection, the parent element is being "un-hovered", if you will. To put it another way, when I try to select something from the dropdown, the whole thing hides itself again. I'm sure it has something to do with the way IE interprets the stylesheet, but I don't know what or where. Here is some relevant code (edited for clarity): #toolBar .toolTip { position: absolute; display:none; background: #fff; line-height: 1em; font-size: .8em; min-width: 300px; bottom: 47px; left: -5px; padding: 0 ; } #toolBar div:hover .toolTip { display:block; } and <div id="toolBar"> <div class="socialIcon"> <a href=""><img src="/im/social/nytimes.png" alt="NY Times Bestsellers" /></a> <span class="toolTip"> <h1>NY Times Bestsellers Lists</h1> <div id="nyTimesBestsellers"> <?php include('/ny-times-bestseller-feed.php') ?> </div> <p><img src="/im/social/nytimes.png" alt="NY Times Bestseller Lists" /> Change List <select id="nyTimesChangeCurrentList" name="nyTimesChangeCurrentList"> <option value="hardcover-fiction">Hardcover Fiction</option> <option value="hardcover-nonfiction">Hardcover Nonfiction</option> <option value="hardcover-advice">Hardcover Advice</option> </select> </p> </span> </div> </div>

    Just like the question says, I want to be able to use psexec to start Internet Explorer, then load a particular website in the browser. I know how to start IE, just can't make a command that goes to a particular webpage. This is what I have so far: psexec "C:\program files\Internet Explorer\iexplore.exe" I just can't figure the syntax for loading anything other than the default start page Thanks!

  • I want to establish a TCP/IP connection over a UART connection (Windows XP/7)

    - by michael
    I want to connect two computer via serial but for each to see each other via a TCP/IP connection. Ie, create new ethernet ports on the computers that are in actual fact serial ports. The reason for this is that I am actually testing the medium in which the serial connection is made (wireless), and part of the experiment will be to use TCP/IP. Preferably I would use something that I can configure (max packet size and setting serial delimiters).

  • IE7 textbox onfocus problem

    - by Craig
    Because IE won't do document.getElementById(ID).setAttribute('type','password') I've re-engineered the way the password field woirks on this site: http://devdae.dialanexchange.com/Default.aspx so it works in accordance with this idea: http://www.folksonomy.org/2009/01/12/changing-input-type-from-text-to-password-in-internet-explorer-hack/ It works fine in IE8 and FF3. It breaks in IE7 just as you click into the password field. I'm now tearing my hair out. Can anyone give me a clue what's wrong as IE7's diagnosis is just "Object expected, code 0"?
