  • jQuery selector question

    - by Jakey
    I have a span and an anchor inside a table cell. I have the anchor set up to show a tooltip. I would like the text inside the span to be used for the tooltip. How can I select this text in jQuery? <td class="row-head" colspan="5"><span class="tip-text">Complete Coverage</span><a href="#" class="help"></a></td> JQuery code - the current selector always finds the first instance only for all tips. $(document).ready(function() { $('.help').qtip({ style: { name: 'cream', tip: true }, content: { text: $(this).find('span.tip-text').html() } }); }); Thanks

  • Python Multiprocessing Question

    - by Avan
    My program has 2 parts divided into the core and downloader. The core handles all the app logic while the downloader just downloads urls. Right now, I am trying to use the python multiprocessing module to accomplish the task of the core as a process and the downloader as a process. The first problem I noticed was that if I spawn the downloader process from the core process so that the downloader is the child process and the core is the parent, the core process(parent) is blocked until the child is finished. I do not want this behaivor though. I would like to have a core process and a downloader process that are both able to execute their code and communicate between each other. example ... def main(): jobQueue = Queue() jobQueue.put("http://google.com) d = Downloader(jobQueue) p = Process(target=d.start()) p.start() if __name__ == '__main__': freeze_support() main() where Downloader's start() just takes the url out of the queue and downloads it. In order to have the 2 processes unblocked, would I need to create 2 processes from the parent process and then share something between them?

  • Question about Virtual Inheritance hierarchy

    - by Summer_More_More_Tea
    Hi there: I encounter this problem when tackling with virtual inheritance. I remember that in a non-virtual inheritance hierarchy, object of sub-class hold an object of its direct super-class. What about virtual inheritance? In this situation, does object of sub-class hold an object of its super-class directly or just hold a pointer pointing to an object of its super-class? By the way, why the output of the following code is: sizeof(A): 8 sizeof(B): 20 sizeof(C): 20 sizeof(C): 36 Code: #include <iostream> using namespace std; class A{ char k[ 3 ]; public: virtual void a(){}; }; class B : public virtual A{ char j[ 3 ]; public: virtual void b(){}; }; class C : public virtual B{ char i[ 3 ]; public: virtual void c(){}; }; class D : public B, public C{ char h[ 3 ]; public: virtual void d(){}; }; int main( int argc, char *argv[] ){ cout << "sizeof(A): " << sizeof( A ) << endl; cout << "sizeof(B): " << sizeof( B ) << endl; cout << "sizeof(C): " << sizeof( C ) << endl; cout << "sizeof(D): " << sizeof( D ) << endl; return 0; } Thanks in advance. Kind regards.

  • Question of using static_cast on "this" pointer in a derived object to base class

    - by Johnyy
    Hi, this is an example taken from Effective C++ 3ed, it says that if the static_cast is used this way, the base part of the object is copied, and the call is invoked from that part. I wanted to understand what is happening under the hood, will anyone help? class Window { // base class public: virtual void onResize() { } // base onResize impl }; class SpecialWindow: public Window { // derived class public: virtual void onResize() { // derived onResize impl; static_cast<Window>(*this).onResize(); // cast *this to Window, // then call its onResize; // this doesn't work! // do SpecialWindow- } // specific stuff };

  • Objective-C subclasses question

    - by Johannes Jensen
    I have a class called Level, which is a subclass of NSObject. Then I have a class called Level_1_1 which is a subclass of Level. Is it allowed to type like Level* aLevel = [Level_1_1 alloc]; instead of Level_1_1* theLevel = [Level_1_1 alloc]; ? :) I try it and I don't get any warnings, just wondering if it's okay to do?

  • question about asynchronous http

    - by rantravee
    Hi , I just want to check if I understood well the way asynchronous Http request work on Android. Suppose I make such a request and set a ResponseHandler<String> responseHandler to handle the response. By doing this is it possible to have the UI thread blocked waiting for the response ? The implication being that the code in the function: public String handleResponse(HttpResponse response) is also executed on the UI thread or is there silently spawned a thread that waits for the response and calls the handleResponse(HttpResponse response) function when the response arrives ?

    How can I simply the below if statements? if ( isset(var1) & isset(var2) ) { if ( (var1 != something1) || (var2 != something2) ) { // ... code ... } } Seems like this could be condensed to only one IF statement but am not certain if I'd use an AND or OR

  • Custom membership provider via WCF authorization question

    - by Diego
    I've made a global authentication via WCF to use with the most of our systems, but found that load data via WCF not very so fast. What I need to do now is verify every time that the page is loading if the user has access granted to that page.... Its a good pratice to go back in WCF request this info for every page that the user access?This will not slow down my entire system?

  • Question about ITextUndoHistory returned from TryGetHistory

    - by nick.ueda
    Everytime the IWpfTextView's TextBuffer changes I am trying to get the history's redostack and undostack and simply checking the count. When doing this I am encountering a "Method not supported exception" when trying to access the two stacks. Am I retrieving the history incorrectly or does VS not want me seeing/editing the contents of the stacks? I can post the code if necessary... Thanks, Nick

  • Algorithm Question Maximize Average of Functions

    - by paradoxperfect
    Hello, I have a set of N functions each denoted by Fi(h). Each function returns some value when given an h. I'm trying to figure out a way to maximize the average of all of the functions given some total H value. For example, say each function represents a grade on an assignment. If I spend h hours on assignment i, I will get g = Fi(h) as my grade. I'm given H hours to finish all of the assignments. I want to maximize my average grade for all assignments. Can anyone point me in the right direction to figure this out?

  • C++ - Resources in static library question

    - by HardCoder1986
    Hello! This isn't a duplicate of http://stackoverflow.com/questions/531502/vc-resources-in-a-static-library because it didn't help :) I have a static library with TWO .rc files in it's project. When I build my project using the Debug configuration, I retrieve the following error (MSVS2008): fatal error LNK1241: resource file res_yyy.res already specified Note, that this happens only in Debug and Release library builds without any troubles. The command line for Resources page in project configuration looks the same for every build: /fo"...(Path here)/Debug/project_name.res" /fo"...(Path here)/Release/project_name.res" and I can't understand what's the trouble. Any ideas? UPDATE I don't know why this happens, but when I turn "Use Link-Time Code Generation" option on the problem goes away. Could somebody explain why does this happen? I feel like MS-compiler is doing something really strange here. Thanks.

  • Fibonacci Function Question

    - by DMan
    I was calculating the Fibonacci sequence, and stumbled across this code, which I saw a lot: int Fibonacci (int x) { if (x<=1) { return 1; } return Fibonacci (x-1)+Fibonacci (x-2); } What I don't understand is how it works, especially the return part at the end: Does it call the Fibonacci function again? Could someone step me through this function?

  • Reporting Services Textbox Format Question

    - by coson
    Good Day, I am creating a report with Reporting Services and am using several text boxes horizontally aligned next to each other. I would like to put periods so that report looks like: 1234 Robert Jones................... (234) 921-4922 1235 Jennifer Wilson................ (919) 582-2914 Is this possible to right-pad the text box with periods, or would I need to roll out some code to accomplish the above effect. I tried doing this and the results looked like: 1234 Robert Jones............... (234) 921-4922 1235 Jennifer Wilson.......... (919) 582-2914 Is something like this even possible? TIA, coson

  • Design question for windows application, best approach?

    - by Jamie Keeling
    Hello, I am in the process of designing an application that will allow you to find pictures (screen shots) made from certain programs. I will provide the locations of a few of the program in the application itself to get the user started. I was wondering how I should go about adding new locations as the time goes on, my first thought was simply hard coding it into the application but this will mean the user has to reinstall it to make the changes take affect. My second idea was to use an XML file to contain all the locations as well as other data, such as the name of the application. This also means the user can add their own locations if they wish as well as sharing them over the internet. The second option seemed the best approach but then I had to think how would it be managed on the users computer. Ideally I'd like just a single .exe without the reliance on any external files such as the XML but this would bring me back to point one. Would it be best to simply use the ClickOnce deployment to create an entry in the start menu and create a folder containing the .exe and the file names? Thanks for the feedback, I don't want to start implementing the application until the design is nailed.

  • Question about factory classes

    - by devoured elysium
    Currently I have created a ABCFactory class that has a single method creating ABC objects. Now that I think of it, maybe instead of having a factory, I could just make a static method in my ABC Method. What are the pro's and con's on making this change? Will it not lead to the same? I don't foresee having other classes inherit ABC, but one never knows! Thanks
