  • doxygen with IDL/ODL

    - by John
    If you have a C++ project that has a bunch of .ODL files and the generated .h files from the ODL compiler, should doxygen be told to parse both .odl and .h, or only one or the other? In general I don't like documenting generated code but IDL is sort of a special case. In any case, it seems like the member listing of ODL files is not quite working properly in my tests, are ODL files properly parsed?

  • How can I know when QProcess wants to read input?

    - by mpcabd
    I'm implementing a compiler in my Compilers class, I'm using Qt & C++. After I have generated the machine code from the source code, I'm executing the virtual machine that will execute the call. I'm facing a problem here, I'm using readyRead() signal to get output from the virtual machine, but how can I know that the virtual machine wants to read data from the user? I wanna show the user an input dialog each time the machine asks for input.

  • Click() works in IE but not Firefox

    - by Tom Andrews
    I have code which is trivial but only works in IE not Firefox. $(document).ready(function(){ $('li#first').click(); }); I have also tried: document.getElementById('first').click(); But that doesn't work either. Is this an IE bug/feature or is click() not supported in the other browsers? Thanks in advance.

  • Creating an instance within the Class itself

    - by didxga
    What's going on when the assignment statement executed at Line 4, does compiler ignore the new operator and keep the foo variable being null or something else happen to handle this awkward moment? public class Foo { // creating an instance before its constructor has been invoked, suppose the "initializing" // gets printed in constructor as a result of the next line, of course it will not print it private Foo foo = new Foo();//Line 4 public Foo() { System.out.println("initializing"); } }

  • sizeof float (3.0) vs (3.0f)

    - by kumar
    Hi, What is the difference between sizeof(3.0) and sizeof(3.0f) I was expecting both of them to give the same result (sizeof float)..but its different. In 32 bit machine,gcc compiler, sizeof(3.0f) =4 sizeof(3.0) = 8 Why so?

  • mysqldump problem with case sensitivity? Win->linux

    - by acidzombie24
    When i dump a table with uppercase letters using mysqldump it comes out as lower case in my dump.sql file. I found a report here in 2006, almost 4 years old http://bugs.mysql.com/bug.php?id=19967 A solution here suggest making linux insensitive. I rather not if possible. Whats the easiest way to copy a win32 db into linux?

  • Why use Visual Studio 6 for C++

    - by robUK
    Hello, I am just wondering why programmers who program in C++ for windows always use Visual Studio 6 instead of Visual Studio 2008? Isn't the compiler in 2008 much better than the one in VS6? The reason I ask as I have used many sdk's that are always written in VS6? Many thanks, Steve

  • Constructor for an immutable struct

    - by Danvil
    Consider the following simple immutable struct: struct Stash { public int X { get; private set; } public Stash(int _x) { X = _x; } } This is not working, because the compiler wants me to initialize the "backing field" before I can access the property. How can I solve this?

  • How can I close a JFrame by click on a button?

    - by Roman
    I would like to have a button in my window such that if I click it (button) the window is closed. I found out that I can close a window in the following way: referenceToTheFrame.hide(); //hides the frame from view refToTheFrame.dispose(); //disposes the frame from memory But if I do this way, compiler complains: Note: myProgram.java uses or overrides a deprecated API Note: Recompile with -Xlint:deprication for details. Do I do something unsafe?

  • How to define custom exception class in Java, the easiest way?

    - by yegor256
    I'm trying to define my own exception class the easiest way, and this is what I'm getting: public class MyException extends Exception {} public class Foo { public bar() throws MyException { throw new MyException("try again please"); } } This is what Java compiler says: cannot find symbol: constructor MyException(java.lang.String) I had a feeling that this constructor has to be inherited from java.lang.Exception, isn't it?

  • Are 'const' variables precomputed by default in C++?

    - by Gunnar
    Suppose I have variables for positions like const float latitude = 51.+11./60.+33.0461/3600.; const float longitude = 12.+50./60.+31.9369/3600.; and use them frequently in the program. Does the compiler precompute that? (This example should not produce much overhead, but you get the point.) Bonus point for pointing out location. ;) TIA

  • AIX- Does not install shared lib

    - by kadeshpa
    I am able to build the shared object successfully using the holy native compiler "xlc" on AIX.It does build the shared object library but does not install the shared object library. Configure command is: ./configure --prefix=/PATH/to/install --exec-prefix=/PATH/to/install --enable-shared --enable-static=no --enable-module=so --build=powerpc-ibm-aix5.3.0.0 --host=powerpc-ibm-aix5.3.0.0 LDFLAGS="-G -shared" Any help would be appreciated?

  • [C++] Is it possible to roll a significantly faster version of sqrt

    - by John
    In an app I'm profiling, I found that in some scenarios this functions are able to take over 10% of total execution time. I've seen discussion over the years of faster sqrt implementations using sneaky floating-point trickery, but I don't know if such things are outdated on modern CPUs. MSVC++ 2008 compiler is being used, for reference... though I'd assume sqrt is not going to add much overhead though.

  • How to see list of html-tidy errors in VIM for Windows?

    - by stumbling
    I am using Vim 7.2 on WinXP. I've tired to run tidy like this: :compiler tidy :make :copen When I do :copen it shows me no errors to jump to. I've seen references that shellpipe might need to be set a specific way, but that refers to an earlier version of VIM. How should I be using HTML-tidy with VIM, and do I need to mess with shellpipe to get it to work with WinXP?

  • Is this a correct syntax (c code found on wikipedia)?

    - by m4design
    I just found this code on wikipedia. Link: http://en.wikipedia.org/wiki/Sizeof#Use The code: /* the following code illustrates the use of sizeof * with variables and expressions (no parentheses needed), * and with type names (parentheses needed) */ char c; printf("%zu,%zu", sizeof c, sizeof(int)); It states that: "The z prefix should be used to print it, because the actual size can differ on each architecture." I tried it on my compiler, but it gives the following result: 'zu,zu'

  • JQTouch Pressure Sensitivity

    - by rson
    I noticed an interesting bug with the JQTouch platform and wanted to know if anyone else has run into it our has a workaround for it. If I have a link with an onclick event and lightly tap the link on the iPhone, the link works, but the click event is not fired. If I tap the same link harder, the event fires. Any thoughts on this?

    Switching aged 2003 SRV to 2008 caused my Asp.net 2 application fail: The application is no more loading the required library DLL from /bin/ folder anymore.

Compiler Error Message: BC30002: Type 'Facebook.Entity.User' is not defined.
