dev-cpp-users Mailing List for Dev-C++

Hello,
 
    Again, I seek your advice on a personal project : 
       I have searched for information related to the impact that managing, or more accurately not managing memory, will have on processes in win32.
       Recently I have stumbled upon a paper disserting the effects of the paging process on windows, and the cost of requesting more resources than those currently addressed by the front-end virtual memory manager.
       As I envision, the final code will use a great deal of memory, and actually, it will not always be coded by me, and as such, I cannot be certain that the allocated resourced will ever be freed.
       I am quite the control freak, so I'm trying to implement one of two designs :
 
       a ) The software will contain one to several objects that allocate memory, at program start, based on the latest data retrieved from executions with high volume processing, or by other words, I'll subject my code to stress-tests, and register memory usage, for reserving it, on next program restart. I'll, obviously, be managing the memory, providing by one defined interface, my own allocation/freeing routines that will manage the already reserved memory(from the OS).
       b ) All objects within the software will, somehow ( Haven't yet figured this out ) manage its own memory, having this way some information about the memory, besides its start address and the span of it.
 
 
       To sum up, and finally presenting my question : which design would be better, and which would provide more information about the memory usage?
       The above points are, obviously, based on my belief that the system( OS, L2,L1 caches, processor, ram ) will handle better paging out/in virtual memory, than actually reserving it at a latter state, especially, at different points in program logic, since the locality is not observed, on, for instance, linked-list implementations, and processor-cycles will be 'wasted' in finding available memory in kernel/c-runtime area.
 
Please do correct me if my assumptions are not correct, and, please advice me if you have measurable results related to such implementations... This is a pet project, and although I am pursuing it by sheer fun, I believe it can be brought to good use.
 
 
Sincerely
Frederico Marques

No, no license problems. You may develop commercial applications using the
Dev-C++ IDE or the MinGW tool chain.

Hello.

I have question regarding the licence terms.
Is anykind restriction about software, developed by Dev-Cpp IDE put on it ?
(I don't mean to change source of Dev-Cpp, just write some commercial applications by it, without visibility or access to generated code of application of course).

Thank You, Bartek.

Do you have any space in any directory name?

You should avoid having the source code in a directory with spaces, such
as "Documents and Settings".

This is what is in the error log . when the compile terminates . with the
Permission denied .

Permission Denied . the log says not authorized to the file . I was told
this happens when the program is running . Nothing is running.

 

Any suggestions. I have reloaded the software more than once!!

How do you know that nothing is running. A hung application - or a hung
linker or compiler - will stay in memory and lock files. Have you really
scanned all applications in the Task Manager? Have you tried to reboot?

Depende, si lo que   quieres es desarrollar interfaces de usuario, hay varias, prueba con wxWidget o FLTK. Si quieres desarrollar juegos, Allegro parece ser muy bueno.

Buenos días,
Existe algun paquete de Dev-C++ que permita desarrollar aplicaciones Win32 en un entorno gráfico, o por lo menos un paquete que haga más facil hacer la interfaz gráfica en en ambiente windows?

I'm having a bit of trouble understanding template partial
specialization. Here is an example that I was given with type traits:

template <typename T>
class TypeTraits {
private:
    template <typename U>
    struct PToMTraits
    {
        enum {result = false};
    };
    template <typename U,typename V>
    struct PToMTraits<U V::*>
    {
        enum {result = true};
    };


What does this mean? When I removed the specialization <U V::*> from the
second PToMTraits, I received an error that I had redefined the
PToMTraits struct with two arguments. When else can you redefine a
template struct with two arguments?

Hello...

 

  I am trying to get any file such as images, word documents, etc... and save it in a buffer inside my program. The issue is that when I create a file with another name but with the same extension as the file in the buffer, the file doesn't work. It's corrupted. I am trying to get any file and save it in a buffer. 

 

This is my code:

 

    ofstream out("image2.jpg");
    ifstream in("image.jpg");
    
    if(!out || !in)
    {
      cout<<"ERROR"<<endl;
      system("pause");
      return 0;
    }
    
    char *buffer;
    int size = 0;
    char c;
    
    in.seekg(0,ios::end);
    size = in.tellg();
    in.seekg(0,ios::beg);
    
    buffer = new char[size];
    strcpy(buffer,"");
    
    for(int x=0;x<=size;x++)
    {
      if(in.good())
      {
        c = in.get();
        buffer[x] = c;
      }
    }
    
    out.write(buffer,size);
    
    out.close();
    in.close();

Oh OK. Thanks again for your help.


So... one question... because the recv function receives only string(char*); do I have to break it down to find the (for example) the 'GET' method then look after a space line to find what is requesting?

Thanks for trying to answer but like i said... I really don't want to use no other external libraries like curl or chilkat or WinNet or any other... I want to know how does a server process HTTP requests by just using #include <winsock2.h> and no other winsock base libraries.

Hello,

   Well, I got tire of looking around on google...
So, why not ask here, maybe someone will tell me the answer...

How can I process HTTP requests using plain windows sockets. No external library.
I just want to get the idea for learning purpose.

Thanks
