  • penalty for "inlined" classes

    - by 2di
    Hi All Visual studio allow you to create "inlined" classes (if I am not mistaken with the name). So class header and implementation all in one file. H. file contain definitions and declarations of the class and functions, there is no .cpp file at all. So I was wondering if there is any penalty for doing it that way? any disadvantages ? Thanks a lot

  • using declarations in main (C++)

    - by Crystal
    Although you wouldn't want to do this, if you have a namespace COMPANY, and a class in that namespace SOMECLASS. Why is it that in the .cpp file, you might define the functions as COMPANY::SOMECLASS::someFunction() {} But in main, you don't do int main() { COMPANY::SOMECLASS::someFunction(); } but instead you declare the namespace and do something like: using COMPANY::SOMECLASS; int main() { someFunction(); }

  • Passing around an ElementTree

    - by PulpFiction
    Hello. In my program, I need to make use of an ElementTree object in various functions in my program. More specifically, I am doing this: tree = etree.parse('somefile.xml') I am passing this tree around in my program. I was wondering whether this is a good approach, or can I do this: Create a global tree (I come from a C++ background and I know global is bad) Create the tree again wherever required. Or is my approach ok?

  • How to get parallel behavior in Java Script ?

    - by Biswanath
    More or less I want to execute two functions in parallel. One way as I see is doing through SetTimeOut function. I have not completely gone through the ReactiveExentension, although it looks promising but may be overkill for my needs. Is there any framework which supports parallelism ? My use case is trivial, but I would like to know if anybody heavily needed parallelism in Java Script ? Thanks, Biswanath.

  • C++ code generation with Python

    - by norapinephrine
    Can anyone point me to some documentation on how to write scripts in Python (or Perl or any other Linux friendly script language) that generate C++ code from XML or py files from the command line. I'd like to be able to write up some xml files and then run a shell command that reads these files and generates .h files with fully inlined functions, e.g. streaming operators, constructors, etc.

  • Can we write an EOF character ourselves?

    - by Apoorv
    Most of the languages like C++ when writing into a file, put an EOF character even if we miss to write statements like : filestream.close However is there any way, we can put the EOF character according to our requirement, in C++, for an instance. Or any other method we may use apart from using the functions provided in C++. If you need to ask more of information then kindly do give a comment. Thanks in advance.

  • Is it possible to get a graphical representation of gprof results?

    - by Werner
    Hi, I am interested in getting the profiling of some number crunching program. I compiled it with -g and -pg options and linked it and got it gmon.out. After reading the info (plain text) it looks a bit ugly. I wonder if there are some open source tools for getting a graphical representation of the 10 functions where the program spends the most of the time as well as a flux diagram. Thanks

  • Why is T() = T() allowed in C++?

    - by Rimo
    I believe the expression T() creates an rvalue (by the Standard) However the following code compiles (at least on gcc4.0) class T {... }; int main() { T() = T(); } I know technically this is possible because member functions can be invoked on temporaries and the above is just invoking the operator= on the r-value temporary created from T(). But conceptually this is like assigning a new value to an r-value. Is there a good reason why this is allowed?

  • How does one programmatically download files from the web?

    - by ytrp
    How are files downloaded from servers in programming languages like C? I understand higher level languages have magic functions like "download_file_from_url()" but they don't help me understand what is actually going on. I'm a little familiar with sockets but network programming in general is still a black box to me. Thanks for any help.

  • FORTRAN: determine variable type

    - by tibbs
    hello, GOOGLE has yet to find an answer for me, so here goes: In FORTRAN, is there a way to determine the TYPE of a variable? E.G., pass the variable type as an argument in a function, to then be able to call type-specific code with that fuction; eliminating the need to have seperate similar functions for each data type. thanks.

  • jQuery: what if I don't have mouseleave function ?

    - by Patrick
    hi, I'm using Drupal for a website and I can only use jQuery 1.2.7 (not the most recent versions). I want to fade in / fade out a div element and I'm using mouseover / mouseout functions. However, this element contains some children and when I move the mouse over it, the mouseout function is triggered, because I'm moving over one of its children. Since I don't have mouseleave function, how can I solve this issue ? thanks

  • What's the difference between $get and $find in JavaScript?

    - by RoboShop
    Hi, I'm a .NET programmer who've just started to learn more about client side scripting, and I was wondering sometimes you use $get('value') and $find('value') and I've discovered that these are just shortcuts for document.getElementById('value') and Sys.Application.findComponent('value'), respectively. However, I still don't understand: what is the difference between these two functions in JavaScript? What exactly are they looking up/retrieving when invoked? Thanks in advance.

  • Why can't I make my parameter like this?

    - by mystify
    - (void)setPropertyValue:(const *void)inValue forID:(UInt32)propertyID { } The compiler doesn't like the const *void, for some reason. When I have that, it says: error: expected ')' before 'void' When I make the parameter like (UInt32)foo there is no problem. Does const *void only work in functions? I need a parameter which can be a "pointer to anything" like UInt32, Float64, etc.

  • Database advantages? Access, MySQL, msSQL, or any others?

    - by JimZ
    Dear all Stackoverflowers, I just started to learn programming and now I'm putting this question online based on a quote: no question is silly My work needs to develop a order system based on web, which wants a database system. Since using Excel for years as a general office user, I naturally turn this to Access. However, most people say Access is very limited comparing to MySQL or MSSQL, or any other more professional database system. But after developing some functions for my company's order system, I really find Access can fulfill my request. And I also tried MSSQL to develop, which I found it not quite convenient to use. I have searched in stackoverflow and find no general answer about my doubt. Now I am sincerely hoping some experienced and professional developers could clear my doubts. Now I'm listing some Access advantages, which I don't think other database system have. I hope you could help me also find these advantages in others. 1. Access is portable, I can just copy a xxx.accdb file to my company and continue with development. 2. Access is easy to generate helpful table, for example, it will automatically generate a field that can automatically count, could be used as primary key value. 3. it is more compatable with Excel, to display and filter data. 4. importantly, it nerely needs no environment to setup, just needs MS Office to be installed. ............others However, I also find some points that MSSQL is advantaged: 1. security reasons 2. easy to backup, ( just use BACKUP..... sql statement to do it) 3. can edit stored procedure to save some functions to database ...............others specifically, I wish some friends could tell me how to make other database portable? since I usually work both at home and in office. It's a headache to move MSSQL work to my office, since the version of MSSQL is not the same. Thank you all and best regards, :)

  • Video For Windows disable FILE_FLAG_NO_BUFFERING

    - by cunzlow
    I am using Video For Window's AVIFile functions. When I use AVIFileOpen I notice that it uses the flag FILE_FLAG_NO_BUFFERING when creating the .avi file. ProcessMonitor shows the that file was created with "no buffering". This flag is causing performance issues and I was wondering if there is a way to use this function without that flag.
