  • HTML to automatically hide text depending on scrolled size (like in Gmail)?

    - by Stephen Cagle
    Look at your Gmail inbox. You have 3 main columns contains the Sender contains "THE_EMAIL_SUBJECT - THE_EMAIL_BODY" the date the email was sent on I note that when you resize the window, the Gmail web client automatically resizes the displayed text in the second column. It basically just truncates the text so that it always can display the sent on date to the right, and the sender to the left. It is a pretty neat effect, and I would like to have that effect for myself. Does anyone know how to do this in HTML/CSS/JS?

  • SQL to get rows (not groups) that match an aggregate

    - by xulochavez
    Given table USER (name, city, age), what's the best way to get the user details of oldest user per city? I have seen the following example SQL used in Oracle which I think it works select name, city, age from USER, (select city as maxCity, max(age) as maxAge from USER group by city) where city=maxCity and age=maxAge So in essence: use a nested query to select the grouping key and aggregate for it, then use it as another table in the main query and join with the grouping key and the aggregate value for each key. Is this the standard SQL way of doing it? Is it any quicker than using a temporary table, or is in fact using a temporary table interanlly anyway?

  • Visual Studio C++ adds "junk" to my programs

    - by sub
    I have looked into the binaries produced by MSVC 2010 from my source code, and saw everything being filled with "junk". I don't know how to explain, but my executables are being added too much unnecessary information, like: Lots of Microsoft default error messages, I don't want them XML schema settings (Why!?) Other things not important for the execution of the main program How can I stop MSVC doing this? Do I have to switch to GCC? In all other programs (written in C++ too, from Word processors to games), this junk simply doesn't exist.

  • C++: Could Polymorphic Copy Constructors work?

    - by 0xC0DEFACE
    Consider: class A { public: A( int val ) : m_ValA( val ) {} A( const A& rhs ) {} int m_ValA; }; class B : public A { public: B( int val4A, int val4B ) : A( val4A ), m_ValB( val4B ) {} B( const B& rhs ) : A( rhs ), m_ValB( rhs.m_ValB ) {} int m_ValB; }; int main() { A* b1 = new B( 1, 2 ); A* b2 = new A( *b1 ); // ERROR...but what if it could work? return 0; } Would C++ be broken if "new A( b1 )" was able to resolve to creating a new B copy and returning an A? Would this even be useful?

  • Collision detection on sub views contained in 2 separate parent UIViews?

    - by Chris
    Hi All, I originally setup some conditions using CGRectIntersectsRect for some collision detection which worked fine. In the greater scale of things I only need part of the view to be detected. So originally within the ViewController it was comparing 2 UIviews. Now what I need to do is collision detection of subViews within 2 different UIViews that are contained in a view in which the view controller does the logic. My script is no longer working as I suspect CGRectIntersectsRect only compares frames within the same view? I'll keep digging to confirm this. Any ways around this? Is it possible for example to get the x and y pos of the sub view in relation to the main view that's performing the logic?

  • Removing Unused (Unreferenced) Static Global Variable Constants in C++

    - by Synetech inc.
    Hi, I have a header file with a few common constants like names and stuff that are automatically included in each project (an example follows). The thing is that they are included in the compiled binary (EXE) whether they are used (referenced) or not. If I use DEFINEs instead, then naturally they are not included if they are not used, but of course consts are better than defines so… I tried Googling it, but the closest thing I could find was a question right here on SO that did not quite help. Matters of i18n aside, how can I keep the ones that are not used out of the binary, while still keeping it easy to use like this? Thanks. //COMMON.H: static const CString s_Company _T("Acme inc."); //etc. static const CString s_Digits _T("0123456789"); //TEST.CPP: #include common.h int main() { AfxMessageBox(s_Company); } //s_Company should be in the final EXE, but s_Digits should not be, but is

  • Please help me get my content div to get an auto height from absolutely positioned element

    - by Justin Hollender
    I need some help with a CSS layout. It is set up like this: +--------------------+ | | | header | |-| |--------------| | |nav| content | | | | | | | | | | | | | | footer | +--------------------+ So, the nav is supposed to be floating above all the main page content. That's why I have it set to be absolutely positioned. The issue is that the nav items are dynamic, without a set height. Right now, the nav expands past the content. How can I fix it so that the content will have an auto height based off the nav? Thanks in advance.

  • How to copy resources from other module to specific location ? (maven)

    - by smallufo
    I have a maven-managed project with some modules. One module contains some native codes inside "src/main/resources/native" directory. Second module packages all related modules to a WAR file. Here comes the question : How to copy the "native/" directory (and its sub-directories) in first module to WEB-INF/native directory in the second module ? I found a copy resources plugin , but it seems not what I want. (It copies directory inside the same module , but I want cross-module copy) Thanks in advanced.

  • Java application return codes

    - by doele
    I have a Java program that processes one file at a time. This Java program is called from a wrapper script which logs the return code from the Java program. There are 2 types of errors. Expected errors and unexpected errors. In both cases I just need to log them. My wrapper knows about 3 different states. 0-OK, 1-PROCESSING_FAILED, 2- ERROR. Is this a valid approach? Here is my approach: enum ReturnCodes {OK,PROCESSING_FAILED,ERROR}; public static void main(String[] args) { ... proc.processMyFile(); ... System.exit(ReturnCodes.OK.ordinal()); } catch (Throwable t) { ... System.exit(ReturnCodes.ERROR.ordinal()); } private void processMyFile() { try { ... }catch( ExpectedException e) { ... System.exit(ReturnCodes.PROCESSING_FAILED.ordinal()); } }

  • Mysql database structure...

    - by Patrick
    I'm creating a members site, and I'm currently working on the user Preference settings. Should I create a table with all the preference fields (about 17 fields) or should I include them in the main member table along with the account settings? Is there a limit as to how many fields I should have in a table? currently the member table has about 21 fields... not sure if its okay to add another 17 more fields when I can easily just put them in another table. It'll take more coding to pull up the data though... any sugguestions?

  • How to handle redirections with codeigniter?

    - by SinneR
    Hi, im having problems starting a codeigniter project, the problem is that when i do something in a controller and then i want a page to display the result, an example: i have a form to add a item to the database, i get all the data in the controller and save it to database and then i want (if all went well) to redirect to the main page with a success msg, i was doing this with $this->load->view('admin', $data); the problem is that the url keeps saying admin/addItem so everytime the page gets refreshed it adds another item, now i found the: redirect('admin','refresh'); but this only helps me when i dont need to display any msg because this function dont allow to send a $data var. Any ideas? Probably this is really easy to fix but i cant find a way to handle the flow of the application the way i want, any help is apreciated. thanks ;)

  • Dynamic memory allocation with default values

    - by viswanathan
    class A { private: int m_nValue; public: A() { m_nValue = 0; } A(int nValue) { m_nValue = nValue); ~A() {} } Now in main if i call A a(2);// 2 will be assigned for m_nValue of object A. Now how do we do this if i want to define an array of objects. Also how do we do this if i dynamically create objects using operator new like A *pA; pA = new A[5];// while creating the object i want the parameterised constructor to be //called I hope the question is clear. Do let me know if more explanation is needed

  • Is this syntactically correct?

    - by Borrito
    I have code in one of the source file as follows: #include <stdio.h> #include <math.h> int a ; int b = 256 ; int c = 16 ; int d = 4 ; int main() { if ((d <= (b) && (d == ( c / sizeof(a)))) { printf("%d",sizeof(a) ); } return 0; } I have removed the casts and have simplified on the data names. The sizeof(a) can be taken as 4. I want to know if the the if syntax is a valid one and if so why doesn't it execute? PS : I haven't sat down on this for long due to time constraints. Pardon me if you find a childish error in the code.

  • Why can't I view a directory in Linux?

    - by Thread7
    I am setting up a Linux web server running apache. I uploaded and untared my web sites files. The files in the main directory are all visible when I am SSH'd into the system. However, I am blocked from all subdirectories. If I write: # cd images Then I get the error: -bash: cd: images: Permission denied I am signed in as ec2-user. I untarred the stuff as ec2-user and I doubt there was any permissions in the tar file since I created the archive on a Windows system. The weird thing is that I am the owner of this directory. Here is a snippet of the command: ls -l drw-rw-r-- 19 ec2-user ec2-user 4096 May 4 04:09 images When I do "sudo su" and then type the command cd images everything is fine. Why do I get "Permission denied" as ec2-user if I am the owner and have rw permission?

  • IE7 cutting off image

    - by Kimberley
    Hi all I have 3 divs with rollover images inside them stacked vertically inside my main content div. IE7 is chopping off about three quarters of the bottom div and I can't figure out why. It displays perfectly in all other browsers (even IE6) but IE7 just won't display properly. This is my first website so I still have a lot to learn. I've managed to fix the other IE bugs but just can't figure this one out. Any help appreciated! } .main_content { float: left; width: 816px; background-image: url(Images/evokedesign_bg_tile.png); background-repeat: repeat-y; overflow: hidden; } .portfolio_buttons { float: left; width: 634px;
