  • Position DIV relative to containing DIV Without Moving Other Stuff

    - by yar
    [I'm not sure if this question has been asked, though I've looked around a bit.] I have a DIV inside a DIV. I would like the inner DIV to have a certain position inside the outer div. I'm having some success with this position: absolute; top: 0px;right:0px; but all other divs are getting moved around. I just want it to float on top of the other stuff (float didn't work, of course). Thanks! Edit: The outer div is relative, and I'd like the inner to move with it when the browser is resized. Edit: Sorry, I've figured out the question (but not the answer): if I use right:0px, the inner div stops moving relative to the outer div and starts moving relative to the browser window. Why would that be?

  • C struct print, decode this code?

    - by pauliwago
    I am in the process of studying for a test, and I'm trying to work through some practice problems. I've been working on this a while now..but can't figure it out. Please take a look at the code fragment: union { int i; short x; unsigned short u; float f; } testout; testout.i=0xC0208000; Before I ask the question, can someone please explain to me how the above code works?? My guess is that testout.i=0xC0208000 puts either an int, short, unsigned short, or float and puts the result in that address. (?) The question is what prints out if we write printf("%d", testout.x)? I know we should expect digits....but I have no idea where they are getting the digits from....there is no output. Any explanation would be greatly appreciated. Thanks!

  • Is there an automatic way to remove debugging methods for a release build?

    - by Lewis
    Note: This is an extension of an earlier question I asked here: Do additional function/method definitions increase a program's memory footprint? When I write a class, I usually end up writing several testing/debugging methods, used to make sure the class works as it should, or for printing data to help with debugging, or for unit testing, etc. Is there an easy/automatic way to make a release without these methods, or do I need to manually delete the extra code any time I want to compile a release version? I ask this question both from a C++ and a Java perspective. I'm using Code::Blocks and Eclipse as IDEs, if that plays into the answer somehow.

  • Admin panel - what is the best way to display "static" data in the layout?

    - by rkj
    I'm about to write a admin panel for my CMS written in CodeIgniter. There will be some user information visible at all time - both in the layout's header section and the sidebar. I'm used to do it in a way that I personally hope and think could be done a lot easier, since I'm tired of sending the same parametres to the view over and over again, when it's dynamic data that needs to be displayed on every page anyways (such as unread messages, username, name, status, etc). I'll need controllers and models, I know that, but do I have to pass, just for an example, the user's username, unread messages etc. every time I need to load a view? Should I do some kind of library for this? Now my question is: How would I do it when it comes to best practice and for making it easy to maintain in the future? I hope my question is understandable :)

  • read successive frames OpenCV using cvQueryframe

    - by AtharvaI
    Hi all I have a basic question in regards to cvQueryFrame() in OpenCV. I have the following code: IplImage *frame1,*frame2; frame1 = cvQueryFrame(capture); frame2 = cvQueryFrame(capture); Now my question is: if frame1 is a pointer to the first frame, is frame2 a pointer to the 2nd frame? So will the two cvQueryFrame() calls read successive frames? I thought I'd check myself first but the pointers frame1,frame2 seem to have the same hex value. :s I just need to capture two frames at a time and then need to process them. Thanks in advance

  • this == null; surely not, but yes

    - by pm100
    I would have said that this will segfault but apparently not #include <stdio.h> class foo { public: bool thingy() {return this == 0;}; }; int main() { foo *f = 0; if(f->thingy()) printf("eating hat\n"); } I just expect that 0-xxx will never work. I assume that if we had to do some vtabling it would fail; obviously cannot access any member variables either edit; sorry - no question there. THe question is "are you surprised like me?" and it seems the answer is yes. even though nobody said yes. I got a) of course this will work b) of course this will never work c) it is undefined behavior; your mileage will vary

  • django image managment

    - by Andrey
    I'am new in django. In my project I'am working with images. I don't know how to organize the management of images. I need to dynamically upload the pictures and resize them. First question - what is the best way to dynamically upload images with progress bar and without flash? I found this and this, but I believe there is a better way. Second question. I have to save one image in different sizes. I won't use these thumbnails on my pages, but another application will. Many clients could upload images at the same time. This means that I can not resize all the images at the same time. How should I organize this process? Is there are a better ready-to-use solution for image management issue?

  • What is a good way of coding a file processing program, which accepts multisource data in Java

    - by jjepsuomi
    I'm making a data prosessing system, which currently is using csv-data as input and output form. In the future I might want to add support for example database-, xml-, etc. typed input and output forms. How should I desing my program so that it would be easy to add support for new type of data sources? Should simply make for example an abstract data class (which would contain the basic file prosessing methods) and then inherit this class for database, xml, etc. cases? Hope my question is clear =) In other words my question is: "How to desing a file prosessing system, which can be easily updated to accept input data from different sources (database, XML, Excel, etc.)".

  • how to bind parameters correctly in example below in mysqli?

    - by user1421767
    In old mysql code, I had a query below which worked perfectly which is below: $questioncontent = (isset($_GET['questioncontent'])) ? $_GET['questioncontent'] : ''; $searchquestion = $questioncontent; $terms = explode(" ", $searchquestion); $questionquery = " SELECT q.QuestionId, q.QuestionContent, o.OptionType, an.Answer, r.ReplyType, FROM Answer an INNER JOIN Question q ON q.AnswerId = an.AnswerId JOIN Reply r ON q.ReplyId = r.ReplyId JOIN Option_Table o ON q.OptionId = o.OptionId WHERE "; foreach ($terms as $each) { $i++; if ($i == 1){ $questionquery .= "q.QuestionContent LIKE `%$each%` "; } else { $questionquery .= "OR q.QuestionContent LIKE `%$each%` "; } } $questionquery .= "GROUP BY q.QuestionId, q.SessionId ORDER BY "; $i = 0; foreach ($terms as $each) { $i++; if ($i != 1) $questionquery .= "+"; $questionquery .= "IF(q.QuestionContent LIKE `%$each%` ,1,0)"; } $questionquery .= " DESC "; But since that old mysql is fading away that people are saying to use PDO or mysqli (Can't use PDO because of version of php I have currently got), I tried changing my code to mysqli, but this is giving me problems. In the code below I have left out the bind_params command, my question is that how do I bind the parameters in the query below? It needs to be able to bind multiple $each because the user is able to type in multiple terms, and each $each is classed as a term. Below is current mysqli code on the same query: $questioncontent = (isset($_GET['questioncontent'])) ? $_GET['questioncontent'] : ''; $searchquestion = $questioncontent; $terms = explode(" ", $searchquestion); $questionquery = " SELECT q.QuestionId, q.QuestionContent, o.OptionType, an.Answer, r.ReplyType, FROM Answer an INNER JOIN Question q ON q.AnswerId = an.AnswerId JOIN Reply r ON q.ReplyId = r.ReplyId JOIN Option_Table o ON q.OptionId = o.OptionId WHERE "; foreach ($terms as $each) { $i++; if ($i == 1){ $questionquery .= "q.QuestionContent LIKE ? "; } else { $questionquery .= "OR q.QuestionContent LIKE ? "; } } $questionquery .= "GROUP BY q.QuestionId, q.SessionId ORDER BY "; $i = 0; foreach ($terms as $each) { $i++; if ($i != 1) $questionquery .= "+"; $questionquery .= "IF(q.QuestionContent LIKE ? ,1,0)"; } $questionquery .= " DESC "; $stmt=$mysqli->prepare($questionquery); $stmt->execute(); $stmt->bind_result($dbQuestionId,$dbQuestionContent,$dbOptionType,$dbAnswer,$dbReplyType); $questionnum = $stmt->num_rows();

  • Problems getting git 'server' to work on Windows

    - by Benjol
    I've followed the Tim's article (mentioned in the answer to this question), but - like many others, it seems - I'm stuck when trying do the test clone at the end. I get the fatal: the remote end hung up unexpectedly error, even though my $HOME path seems to be right. Anyone got any pointers to where I might start for debugging this? My git and linux-fu are severely limited... I'm aware of this answer to the same question, but it doesn't apply in my case, I don't get any messages about paths.

  • Performance: Subquerry or Joining

Now my question is what would be faster? if I change TBL.SID to (Select new from helptable where old = tbl.sid) or if I add helptable to the from and do the joining in the where? greets Auro

  • Online webcam chat on web page. Free server and easy-to-implement client?

    - by Oskar Kjellin
    I have a client requesting that his users can use their webcams to talk to each other on his web site. From what I've understood the main thing to use for this is Flash. However as I have not written flash I would like to have something really easy to implement. Of course preferrably free (or trial). The idea of this is that everything but the chat alone is in .net. So the users will not use flash until they are actaully going to talk to each other. So there is no use for rooms here. I've been looking into silverlight some as well. But it seems like silverlight does not offer streaming between users..? I know this question has been asked many times here. But I could not find a suitable answer which is why I post a new question.

  • "Send it to a friend" button on a webpage

    - by kender
    Hey, How often do we see stuff like "Send this page to a friend" on a webpages? Well, I see them quite often. My question is, how do you guys see it's effectiveness? If I hit a webpage that's interesting, and I think my friend would enjoy it, I can just copy the URL from my browser bar, paste it into the email and press "Send" button. In my opinion, it's usually faster and less mistake-aware then the button/link like this on the webpage. In addition, I'm not really sure what this website does with the emails I enter there - don't they store it and then sell for $1/100 addresses to spammers? My question is - when you design a website, do you put such links on the pages (it's often seen on sites with some news/articles)? Does it even make sense?

  • why doesnt' nhibernate support this "exists in list" syntax ??

    - by ooo
    i have the following query and its failing in Nhibernate 3 LINQ witha a "Non supported" exception. Its similar to this question but this question was asked over a year ago so i am positive that the answer is out of date. My DB tables are: VacationRequest (id, personId) VacationRequestDate (id, vacationRequestId) Person (id, FirstName, LastName) My Entities are: VacationRequest (Person, IList) VacationRequestDate (VacationRequest, Date) Here is the query that is getting a "Non supported" Exception Session.Query<VacationRequestDate>() .Where(r => people .Contains(r.VacationRequest.Person, new PersonComparer())) .Fetch(r=>r.VacationRequest) .ToList(); is there a better way to write this that would be supported in Nhibernate? fyi . .the PersonComparer just compared person.Id

  • How should I initialize jQuery?

    - by Reigel
    I have seen this (I'm also using it): $(document).ready(function(){ // do jQuery }) and also this (I have tried lately): (function(){ // do jQuery })(jQuery) both works fine. My question is what is the difference of the two ( except on how it looks ). Which one is more proper to use?. Can you give me some pro's and con's for each? Is there also another way of doing this? (also help me with the title above. SO suggested, "The question you're asking appears subjective and is likely to be closed.") Thanks everyone.

  • Google Play: how dev can give (already purchased) app to customer as a gift?

    - by Tertium
    Yes, SO, I know, it's not a "programmer's" question:) But customers sometimes help us (devs) with our code, so we (devs) shold be grateful. I think answer to my question will be useful for all fellow android devs. User has purchased my app. Refund period (15min) is over of course. Now I'd like to return money to him as a gift, because he helped me in testing a little. If I refund the entire order in Checkout-Orders will user keep my app 'purchased'? I mean will he be able to uninstall and install it again from GooglePlay-MyApps and will app be marked "purchased"? Will Google LVL accept him to run the app? I've done such refunds before, but then they called it "Android Market", and refund was 12h, and there were no LVL. Maybe somebody know another way to make a small gift using Google Play?

  • How do I do division on HH:MM:SS format time strings in C#?

    - by Jake
    I have a series of times that are coming to me as strings from a web service. The times are formated as HH:MM:SS:000 (3 milisecond digits). I need to compare two times to determine if one is more than twice as long as the other: if ( timeA / timeB > 2 ) What's the simplest way to work with the time strings? If I was writing in Python this would be the answer to my question: Difference between two time intervals in Python Edit: What I'm really looking for is a way to get the ratio of timeA to timeB, which requires division, not subtraction. Unfortunately, the DateTime structure doesn't appear to have a division operator. Updated the question title to reflect this.

  • Backbone inheritance - deep copying

    - by Ed .
    I've seen this question regarding inheritance in Backbone: Backbone.js view inheritance. Useful but doesn't answer my question. The problem I'm experiencing is this: Say I have a class Panel (model in this example); var Panel = Backbone.Model.extend({ defaults : { name : 'my-panel' } }); And then an AdvancedPanel; var AdvancedPanel = Panel.extend({ defaults : { label : 'Click to edit' } }); The following doesn't work: var advancedPanel = new AdvancedPanel(); alert(advancedPanel.get('name')); // Undefined :( JSFiddle here: http://jsfiddle.net/hWmnb/ I guess I can see that I can achieve this myself through some custom extend function that creates a deep copy of the prototype, but this seems like a common thing that people might want from Backbone inheritance, is there a standard way of doing it?
