Hi Guys,

Can anyone tell me how to create objects (of a particular class) without
hard coding them? I want the program to prompt me to input a string of
characters then make an object of that name. I have thought of using cin
but I am still unsuccessful. Thanks for your time.

Regards to all!

WinXP GNU 3.4.2
I have this statement in=20
    if(!title.empty())
    {
        this->ustr->assign(title); // Segmentation Fault
    }
Now, dbg reports that:

Does anyone know what this error mean and/or what I can do to get rid of =
the error?

Hi...
   
  Can someone tell me ? What are the library name (or standar package name for Dev-C++) for trying to access and update the Data Base ( SQL Server 2000)  ?
   
  Thanks a lot for your information.
   
  Best regards

I would suggest you rethink your design. You are violating the whole purpose
of OOP and data hiding. Objects are to manipulate their own data, and hide
it from the outside world. Without knowing all of what you are doing. If you
want to be consistent with OOP, I would suggest one of two ways. 

1) Have the outside world create a list and you pass a reference to this
list to your class and let your class operate on it directly.

2) Create method(s) in your class that allows the outside world to iterate
thru the items on your class internal list. Such as some get method or
getNext method.

As for making a member variable public and exposing it to the world, would
violate the whole principle of OOP. Especially because the outside world
would be able to change the list outside of your class. Which defeats the
whole purpose. I personally would do the second suggestion.

-Adam Jones

  HI lloyd 
  The thng u can do is:
  1.Use Scope resolution operator.
  2.declare the data as "protected" or "public".
  I hope this must solve ur problem.

Hi all,
I'm not sure whether I'm addressing the right mailing list or not.
Anyways, I installed the SDL development packages under dev-cpp, and everything
went well (test programs are working fine).
Now my question is: is it possible to debug with dev-cpp an application which
makes extensive use of SDL functions?

Thx.
Stefano

Hi,
 I have a class which creates data structure (let it be a list) as part
of its data. So it is a private member. I would like to "give" this list
to outside world. How should I implement this?? 

please share you ideas....

Thanks,
 Lloyd

Hi,

this only works if you are really using ASCII (no characters above 127) 
and no locale based conversion is applied.
(see 
http://www.wxwidgets.org/manuals/stable/wx_wxstring.html#wxstringfromascii )
To do this assignment with locale based conversion use something like:
centerx=wxString(tempx,wxConvCurrent);
(see 
http://www.wxwidgets.org/manuals/stable/wx_mbconvclasses.html#wxmbconvobjects 
)
The question is, why aren't you staying in wxWidgets space and use 
wxTextFile instead of CTextFile.
This way you wouldn't have to worry about string format conversions.

Also be careful with the line
cfile.InitializeWith((char *)file.mb_str( wxConvUTF8 ));
Are you sure that every Operating System running your software saves its 
filenames in UTF8?
Probably the conversion should be file.mb_str( wxConvFileName );

Regards,
Stefan

I think here is the error. centerx is a wxString and temp is char* and
they are incompatible data types. So if you want to assign temp to
centerx do the following


centerx=wxString::FromAscii(tempx);

[static wxString FromAscii(const char* s)]

  Lloyd

Change function declaration to:

void wxOpengl3D::ReadFile(const wxString & file)

maybe it helps compiler find the exact match.

The first use I see is when developing interfaces, a class with pure virtual
functions. The classic example is the Shape interface, with its draw method.
Then, classes like Rectangle, Triangles etc can implement this method. And
in a loop, you could have a vector of Shapes (sv), and something like this
to draw all shapes:

for_each(sv.begin(), sv.end(), std::mem_fun(&Shape::draw));

Also, many times a child class add functionality to an object. For example,
a MoverClass may have the function move as a member, which updates its
position. An AircraftClass might want to override this move function, to
update its aerodynamic data to, like this:

void AircraftClass::move(){
MoverClass::move();
// update aero data
}

My 2 cents.

Check if you have an invalid file name - you fail to open the file.

I would guess that the incomplete file type is caused by the data type
ifstream being based on a template (basic_ifstream<char>)

Hi all,

I did somthing like:

<--
#include <fstream>

int		len;
ifstream	instream;

instream.open(Filename.c_str(), ios::binary);

instream.seekg(0, ios::end);
len =3D instream.tellg();
instream.seekg(0, ios::beg);

-->

This compiles well but when I run this in the debugger I get instream as
<incomplete type>
and the the instream.tellg(); will return a -1.

This is taken from a exampler at: 
http://www.cplusplus.com/reference/iostream/istream/tellg.html

Has the incorrect len something to do with these incomplete type thing=
=3F

How might I solve the problem=3F

Thanks in advance

Frank

Hi Kristian,
did you try writing 
std::vector<ArvoreB<T> >::iterator it_filho;
instead of 
 
std::vector<ArvoreB >::iterator it_filho; ?
 
Since a few years, compilers tend to think very general about  templates.
For them, It could be that in implementing your function you wish to make  use
of  class ArvoreB<int>.
It is not easy to infer answers to such questions from authoritative
literature (such as C++ templates, The complete Guide by 
D. Vandevoorde and N.M. Josutis) in a way that your compiler agrees.
Regards, Ulrich
