  • Reconstructing simple 3d enviroment(room) from photo

    - by Riz
    I have photo of a room with three walls and floor/ceiling or both. I am trying to reconstruct this room in 3d asking user for minimal input. Right now I use 8 points defined by user, angles of left and right wall(they can be quite different from 90) and one size "InLeftBottom-InRightBottom"(I need to have real size of this room for later use). I have no info about user's camera(I can read EXIF to get FOV and use constant height but this can be only used as additional info). Is this possible to ask user for less info? Maybe it's possible to get wall angles without user interaction? Or maybe I am completly wrong and should use different approach?

  • With HTML and CSS, how to have an image that is vertically aligned with a horizontal line?

    - by sungod000
    I'd like the image on the left to be adjacent to the horizontal line on the right (bottoms lining up flush). It should be responsive so that the line can change widths as needed. Right now, the image is sitting on top of the line, not beside it. Here is the HTML <div> <img src="image.png"> <hr> </div> Here is the CSS img { float:left } hr { width:100% } How to make this happen?

  • Indexing XMLType columns

    - by Chris
    Hello, I am working with a XMLType and currently experiencing significant performance issues and would like to incorporate indexing to the column type. Currently I am taking the approach of using the XMLTable() and XQuery functions to create a virtual table. I would like to use this Virtual Table to create a function based index on the table containing the XMLType, but I am receiving this error: Error report: SQL Error: ORA-00907: missing right parenthesis 00907. 00000 - "missing right parenthesis" *Cause: *Action: This is the index.. any assistance would be greatly appreciated. CREATE INDEX indx_medicinalproduct ON d.ProductName XMLTable('for $i at $a in /safetyreport/patient//drug for $j in $i/medicinalproduct return element r { $i/medicinalproduct }' PASSING s.safetyreport COLUMNS ProductName varchar2(70) PATH 'medicinalproduct') d;

  • Difference in displaying inner div between IE and Chrome

    - by Gaara
    I have this code that has one "outerDIV" that contains an "innerDIV". On chrome the "innerDIV" size is 491px, whereas on IE it is 425px (same as outerDIV). Hence, on Chrome I can see the first two children of "innerdiv": "My test string #1" and "test2". But for IE I can only see the first child. I am not quite sure what the "right" behavior should be, as firefox does the same as IE. However I would like to have IE do the same as Chrome. I have been experimenting with some css styles (mainly overflow and display), but still can't make it right: IE will expand its height instead of its width to make the elements fit. Can you guys help me figure out a way to change the css so that IE will wraps the div elements inline? As a restriction though, I cannot change the width on the HTML. As a benefit, I am using a css that only loads for IE to patch these kind of IE inconsistencies. The same css will NOT load for chrome, so I don't need to worry about messing with chrome when changing the IE CSS. Thanks in advance! <html> <head> <style type="text/css"> <!-- body { font-family: helvetica; } .myContainer { overflow: hidden; border: 1px solid rgba(0, 0, 0, .5); font-size: 14pt; height: 49px; line-height: 49px; overflow: hidden; display: block; } .myContainer > DIV { float: left; white-space: nowrap; display: block; } .myContainer .item:first-child { padding-left: 10px; } .myContainer .item { float: left; padding-right: 32px; } --> </style> </head> <body> <div id="outerDIV" class="myContainer" style="display: block; width: 425px;"> <div id="innerDIV"> <div class="item"> --------My test string #1-------- </div> <div class="item"> ------test2------- </div> <div class="item"> test </div> </div> </div> </body> </html>

  • Grails external Jms broker (active mq)

    - by TheBigS
    I have what will become an 'external' activemq server I'd like grails to be able to talk to. Right now I am just running it on my dev box. Here is what I have setup right now: 1) Run activemq server 2) Run activemq/examples using ant to produce messages 3) View ActiveMQ admin site: http://localhost:8161/admin/queues.jsp verify that messages are in the queue. 4) Follow Mini Tutorial to create the Service and Controller: http://www.grails.org/ActiveMQ+Plugin 5) Configured my Grails resources.groovy file as follows: beans = { jmsConnectionFactory(SingleConnectionFactory){ targetConnectionFactory = { ActiveMQConnectionFactory cf -> brokerURL = 'tcp://localhost:61616' } } } When I run the grails app I get a BindException saying port 61616 is already in use. How do I configure this to use my server that is already running? I've tried changing 'localhost' to '127.0.0.1' and to my LAN ip, but no luck, it keeps trying to setup its own embedded activemq server. Any ideas?

  • Call an anonymous function defined in a setInterval

    - by Tominator
    Hi, I've made this code: window.setInterval(function(){ var a = doStuff(); var b = a + 5; }, 60000) The actual contents of the anonymous function is of course just for this small example as it doesn't matter. What really happens is a bunch of variables get created in the scope of the function itself, because I don't need/want to pollute the global space. But as you all know, the doStuff() function won't be called until 60 seconds in the page. I would also like to call the function right now, as soon as the page is loaded, and from then on every 60 seconds too. Is it somehow possible to call the function without copy/pasting the inside code to right after the setInterval() line? As I said, I don't want to pollute the global space with useless variables that aren't needed outside the function.

  • Linux program - reverse highlighted text

    - by Oren
    I want to develop a program that will run on the background of my Ubuntu 12.04 so when some text is selected in some textbox of any running program and some key-combination is pressed (like ctrl-F12), the text will be cut, reversed, and pasted in the same place. I know some programs that do it on windows. It is useful in some programs and web-pages that do not support right-to-left languages like arabic and hebrew - the letters are printed from left to right so the text becomes reversed. More specifically I need it in Prezi that has this kind of bug in their embedded flash editor (I thought about writing a chrome-plugin, but I don't think such plugin can manipulate the selected text inside a flash objects). Do you know if such a program exist? Where should I start reading in order to develop a program with such capabilities (manipulate selected text in other programs)? Thanks

  • [ASP.NET] Generating images: Alternate font by User Agent (OS)

    - by sinni800
    Hello, I need to generate small images for certain parts of text. Those will have to fit into the text seamlessly. I know I can not make up for every browser font settings available, but how do I have to check for Linux, Mac and Windows users depending on the user agent? I want to use the right font (of the three "Verdana, Arial, Helvetiva") for the right user agent OS. So: How do I check for the OS? What do I have to compare to in the user agent? Where can I get the other two fonts. Does the Windows-included Verdana look the same as the one used on Linux (or, is it free anyway? I don't know much about fonts)? Where do I get Helvetica? Is it Mac OS licensed? Any code examples can be in either c# or VB.NET. I can read both. Thank you in advance.

  • How can I make the boostrap js carousel automatically cycle as soon as the page loads?

    - by Jonathan Larkin
    Using bootstrap.js version 2.02 I'm trying to get the Twitter Bootstrap Carousel to automatically cycle as soon as someone visits my site. Right now, the auto cycling works only after you click one of the cycle buttons at least once. I want the carousel to begin cycling at the interval right away. Does anyone know how to do this? My site is hotairraccoon.com You'll see how after you click the carousel once, it begins to cycle every 5 seconds or so, but I don't want the click to be required to reveal carousel content. Thanks!

  • Xcode 3.2 not recompiling changed files

    - by Jason
    I've been programming a new iPhone application and everything has been chugging along fine, until this afternoon when I noticed that any changes I was making were not being reflected in the actual app! Even code that throws errors isn't getting picked up by the compiler. To get around this, I have taken to the following procedure: Finish making my edits, and add code to the file which will always throw a compiler error. Right-click the file I have just edited, and hit "Compile" to just compile that one file; it will throw the error. Remove the error-producing code, and again right-click and "Compile" the one file. Build the whole project This is quite annoying, and I can't figure out why this would suddenly happen to my Xcode project. Any thoughts on what could be causing this, and how to fix it?

  • highlight search keywords on hover

    - by fusion
    i've a basic php search form which highlights the keywords using css. i was wondering if i could make the keywords in the results highlight only when the user hovers over the record. is this possible? this is the highlight code: function highlightWords($text, $words) { preg_match_all('~\w+~', $words, $m); if(!$m) return $text; $re = '~\\b(' . implode('|', $m[0]) . ')~i'; $string = preg_replace($re, '<span class="highlight">$0</span>', $text); return $string; } . . . <table class="result"> <?php while ($row= mysql_fetch_array($result, MYSQL_ASSOC)) { $cQuote = highlightWords(htmlspecialchars($row['cQuotes']), $search_result); ?> <tr> <td style="text-align:right; font-size:15px;"><?php h($row['cArabic']); ?></td> <td style="font-size:16px;"><?php echo $cQuote; ?></td> <td style="font-size:12px;"><?php h($row['vAuthor']); ?></td> <td style="font-size:12px; font-style:italic; text-align:right;"><?php h($row['vReference']); ?></td> </tr> <?php } ?> </table> css: table.result tr:hover { background:#F7F7F7; } .highlight { font-weight:bold; color: #DE2842; padding:5px; padding-right:2px; background: #FFFCDB; } i tried changing the color through highlight:hover, but this changed the color of the search keyword only when i hovered over the keyword itself, which is understandable since that's the way it is supposed to work, but i'd like the search keywords to be highlighted when i hover over the result as a whole.

  • Was: Not unique table :: Now: #1054 - Unknown column - can't understand why!?

    - by Andy Barlow
    Hi! I'm trying to join some tables together in MySQL, but I seem to get an error saying: #1066 - Not unique table/alias: 'calendar_jobs' I really want it to select everything from the cal_events, the 2 user bits and just the destination col from the jobs table, but become "null" if there arn't any job. A right join seemed to fit the bill but doesn't work! Can anyone help!? UPDATE: Thanks for the help on the previous query, I'm now up to this: SELECT calendar_events.* , calendar_users.doctorOrNurse, calendar_users.passportName, calendar_jobs.destination FROM `calendar_events` , `calendar_users` RIGHT JOIN calendar_jobs ON calendar_events.jobID = calendar_jobs.jobID WHERE `start` >= 0 AND calendar_users.userID = calendar_events.userID; But am now getting an error saying: #1054 - Unknown column 'calendar_events.jobID' in 'on clause' What is it this time!? Thanks again!

  • Yet Another Simple Retain Count Question

    - by yar
    [I'm sure this is not odd at all, but I need just a bit of help] I have two retain properties @property (nonatomic, retain) NSArray *listContent; @property (nonatomic, retain) NSArray *filteredListContent; and in the viewDidLoad method I set the second equal to the first self.filteredListContent = self.listContent; and then on every search I do this self.filteredListContent = [listContent filteredArrayUsingPredicate:predicate]; I thought I should do a release right above this assignment -- since the property should cause an extra retain, right? -- but that causes the program to explode the second time I run the search method. The retain counts (without the extra release) are 2 the first time I come into the search method, and 1 each subsequent time (which is what I expected). Some guidance would help, thanks! Is it correct to not release?

    Please see pic, this is what I want to do. I am really struggling to bloody do it lol. The master div, is 600px wide ( blue bg ) and need splitting into two areas, left for the image and right for the text etc. Ignore the vertical divider line The left hand div, is approx 200px wide, and need to specify a min-height of 100px, as the placeholder image which is centered to that div 50% 50% will change size, as I will be adding another div like this with larger image placeholder.

  • Define and return a struct in c

    - by nevan
    I'm trying to convert some code from Javascript to c. The function creates an array (which always has a fixed number of items) and then returns the array. I've learned that in c it's not straightforward to return an array, so I'd like to return this as a struct instead. My c is not all that great, so I'd like to check that returning a struct is the right thing to do in this situation, and that I'm doing it the right way. Thanks. typedef struct { double x; double y; double z; } Xyz; Xyz xyzPlusOne(Xyz addOne) { Xyz xyz; xyz.x = addOne.x + 1; xyz.y = addOne.y + 1; xyz.z = addOne.z + 1; return xyz; }

  • Shouldn’t GridView’s RowStyle-HorizontalAlign property overwrite CSS’s text-align property?

    - by AspOnMyNet
    a) As far as I know, GridView’s RowStyle-HorizontalAlign property should overwrite CSS’s text-align property, and thus text inside GridView's cells should be located on the left side of the cells, but is instead moved to the right side. Why is that? b) Similarly, RowStyle-Font-Bold should overwrite CSS’s font-weight property and thus fonts shouldn’t be in bold. But again, CSS’s property overwrites RowStyle’s Font-Bold property. Why? <div id="someClass"> <asp:GridView ID="gvwShowUsers" runat="server" > <RowStyle BackColor="#FFFBD6" ForeColor="#333333" Font-Bold="false" HorizontalAlign="Left" /> <Columns> <asp:BoundField DataField="UserName" HeaderText="UserName" /> </Columns> </asp:GridView> </div> CSS file: #someClass td { font-weight:bolder; text-align:right; } thanx

  • Using Forms authentication with remote auth system?

    - by chobo
    I am working on a website that uses a remote websites database to check for authentication (they are both share some database tables, but are separate website...) Right now I check the username and password against the remote websites account / member table, if there is a match I create a session. Questions: Is this secure? On authenticated pages I just check if a session of a specific type exists.Is it possible for someone to create an empty session or something that could bypass this? Is it possible to use Forms authentication with this setup? Right now if a user is authenticated I just get an object back with the username, email and id.

  • Controlling the USB from Windows

    - by b-gen-jack-o-neill
    Hi, I know this probably is not the easiest thing to do, but I am trying to connect Microcontroller and PC using USB. I dont want to use internal USART of Microcontroller or USB to RS232 converted, its project indended to help me understand various principles. So, getting the communication done from the Microcontroller side is piece of cake - I mean, when I know he protocol, its relativelly easy to implement it on Micro, becouse I am in direct control of evrything, even precise timing. But this is not the case of PC. I am not very familiar with concept of Windows handling the devices connected. In one of my previous question I ask about how Windows works with devices thru drivers. I understood that for internal use of Windows, drivers must have some default set of functions available to OS. I mean, when OS wants to access HDD, it calls HDD driver (which is probably internal in OS), with specific "questions" so that means that HDD driver has to be written to cooperate with Windows, to have write function in the proper place to be called by the OS. Something similiar is for GPU, Even DirectX, I mean DirectX must call specific functions from drivers, so drivers must be written to work with DX. I know, many functions from WinAPI works on their own, but even "simple" window must be in the end written into framebuffer, using MMIO to adress specified by drivers. Am I right? So, I expected that Windows have internal functions, parts of WinAPI designed to work with certain comonly used things. To call manufacturer-designed drivers. But this seems to not be entirely true becouse Windows has no way to communicate thru Paralel port. I mean, there is no function in the WinAPI to work with serial port, but there are funcions to work with HDD,GPU and so. But now there comes the part I am getting very lost at. So, I think Windows must have some built-in functions to communicate thru USB, becouse for example it handles USB flash memory. So, is there any WinAPI function designed to let user to operate USB thru that function, or when I want to use USB myself, do I have to call desired USB-driver function myself? Becouse all you need to send to USB controller is device adress and the infromation right? I mean, I don´t have to write any new drivers, am I right? Just to call WinAPI function if there is such, or directly call original USB driver. Does any of this make some sense?

  • Drupal subscriptions to taxonomy only

    - by Disco
    Playing around with the subscriptions module; i have some troubles getting it to send the right notification for right subscription. Here's the situation : I have a content-type of type 'work'; it has a cck-taxonomy field; when creating the content users choses one category in which his 'work' fulfills. In user profil, under Categories (user/3/subscriptions/taxa) I choose two categories, lets say 'house work' and 'car work'. When creating a new 'work' content I do not get the notification. But, when manually select 'content-type' in user's profile of type 'work' I get the notification e-mail but independant to which 'category' i had chosen. This is quite annoying since I only want the user to receive his notifications upon the taxonomy he has chosen, not for every new content of type 'work'. Am I missing something obvious here ?
