  • PHP Simplify a ternary operation

    - by Obay
    In PHP, is there a way to simplify this even more, without using an if()? $foo = $bar!==0 ? $foo : ''; I was wondering if there was a way to not reassign $foo to itself if the condition is satisfied. I understand there is a way to do this in Javascript (using &&, right?), but was wondering if there was a way to do this in PHP.

  • How to make all controls of a column the same width

    - by ant18
    Hi I need to know if there's any way of making all controls of a column the same width, and that all these controls are as wide as the cells that contain them. I added a demo on JSFiddle with the controls I'm using. I tried using size for the input texts and style="width:" for the selects , and even though I managed to make them the same width,(it doesn't seem to work in Chrome) it's kinda difficult , that's why I'd like to know if there is any more straightforward way to do the same thing Any ideas or insights?

  • Should I name my solution files in lowercase for SEO?

    - by Scott
    I read that an SEO best practice is to use lowercase urls. Should I name my asp.net webforms project files lowercase as well? Visual Studio doesn't name default documents in new projects all lowercase. I'm not sure it matters since browsing to http://www.mysite.com/mypage.aspx will still work even if your page is named MyPage.aspx. Can somebody enlighten me on this?

  • Remember Chromeless Windows?

    - by AGoodDisplayName
    We used to be able to use javascript in IE to produce a chromeless window...no buttons, scrollbars or even the standard edges of the browser window. My question: Is there any way to accomplish this type of window look from the web with today's browsers?

  • Making a screensaver

    - by user1718744
    No, I'm not talking about making a slideshow of pictures. How can I make the actual file that windows (at least windows 7) uses for screensavers? It is a .scr format, and when I opened it in Notepad, I got a bunch of symbols, with a few words scattered throughout, but that was expected. It looks like it was made with directx, xml, and even assembly (for the shaders) based on the recognizable code there. I just went on to a site-hosting place and made this: Link to ribbons.scr code

  • Weird seg fault problem

    - by bluedaemon
    Greetings, I'm having a weird seg fault problem. My application dumps a core file at runtime. After digging into it I found it died in this block: #include <lib1/c.h> ... x::c obj; obj.func1(); I defined class c in a library lib1: namespace x { struct c { c(); ~c(); void fun1(); vector<char *> _data; }; } x::c::c() { } x::c::~c() { for ( int i = 0; i < _data.size(); ++i ) delete _data[i]; } I could not figure it out for some time till I ran nm on the lib1.so file: there are more function definitions than I defined: x::c::c() x::c::c() x::c::~c() x::c::~c() x::c::func1() x::c::func2() After searching in code base I found someone else defined a class with same name in same namespace, but in another library lib2 as follows: namespace x { struct c { c(); ~c(); void func2(); vector<string> strs_; }; } x::c::c() { } x::c::~c() { } My application links to lib2, which has dependency on lib1. This interesting behavior brings several questions: Why would it even work? I would expect a "multiple definitions" error while linking against lib2 (which depends upon lib1) but never had such. The application seems to be doing what's defined in func1 except it dumps a core at runtime. After attaching debugger, I found my application calls the ctor of class c in lib2, then calls func1 (defined in lib1). When going out of scope it calls dtor of class c in lib2, where the seg fault occurs. Can anybody teach me how this could even occur? How can I prevent such problems from happening again? Is there any C++ syntax I can use? Forgot to mention I'm using g++ 4.1 on RHEL4, thank you very much!

  • Is there memory usage profiler available?

    - by prosseek
    For time profiler for XYZ, I can just run 'time XYZ', or if I have the source code in C/C++, I even can use gprof to get profiled results. Is there any similar tool for memory usage? Is there any tool I can use something like 'memory XYZ', to get info such as min/max/median memory usage? What tool do you use for memory profile with C++/Objective C/C#/Java?

  • News Aggregater of sorts

    - by shinjuo
    There is a website that my company uses that updates information about 3 specific things throughout the day. We use the information from 1 of them and what we are wanting to do is pull this information as it is added to their site and add it to a page of our own to view easier. Is this even possible? Can anyone point me in the direction of setting this up? It is all text that we want to pull.

  • Using C# to read/write from excel spreadsheet.

    - by Aaron
    Hi there, I need to make a program that writes some data to an excel spreadsheet. Something basic along the lines of First name, last name, phone number, e-mail per row with each category in its own column. I don't even know where to start. If someone could tell me which assemblies to reference and maybe point me to a website or a book that covers writing/reading data from an excel spreadsheet via a c# program that would be great. Many thanks.
