[Dev-C++] antivirus

[michele <mic...@li...>]

Probably (quite surely)
was the uninstalling process of my former antivirus to produce the last =
errors, But now after uninstalling dev-cpp, reinstalling it, re-building =
my project,
the problem isn't solved.
Perhaps antivirus esafe in his uninstallation had delete some system =
files (or if non system, at least useful for other programs).
Suggestions?
I hope in some help.

[Dev-C++] dev-cpp and antivirus

[michele <mic...@li...>]

Things got worst,
as about my precedent problem with system("pause")... I unistalled my =
former antivirus, (it is no longer free).
And now I just installed 'avast'... free for home users, but it stops my =
glut applications!!
("GLUT: Fatal error in (unamed): failed to create OpenGL rendering =
context.")
Hard life.

[Dev-C++] Cancel: XP Pro won't let me debug - sorry

[Dev-C++] XP Pro won't let me debug

[Joanna F. <jf...@ve...>]

When I try to run a C++ for Dummies program that has an intentional bug
(to teach debugging), I get a Windows Error Report window advising me
the program has an error and do I want to send a report to Microsoft.
Is there any way to get around this, so I can do the debugging?  (I went
to Options > Compiler options > Linker and checked "Generate debugging
information" but that didn't help.)  I'm using Dev-C++ version 4, Mingw
2.95.2-1 MSVCRT, GDB 4.18, on a Dell Dimension 4600 PC running Windows
XP Pro.  

 

Thanks,

Re: [Dev-C++] operator+ and inheritance

[<or...@vp...>]

Hi!

Thanks for your answer.
I thought about direct access to the base class data, but the base class=20
is also usable "as is". The derived one only extends it with some more=20
info. I already defined an operator+ for the base, so I didn't want to=20
duplicate the same code in the derived class' operator+.

Subject: Re: [Dev-C++] operator+ and inheritance



A lot depends on how you want to handle it.  If you declare

your base data as private, then you'll have to call your

base class operator+ in order to access the sum of the

data in the base class.



However; you can also declare your data in the base class

to be protected, in which case you can access and modify

your base class data directly.



Which method you use is a desing decision.  Do you want to hide

your data as much as possible?  Or is convienent access to your 

data from the derived class more important?  If your operator+

is the only method that need direct access to your base data,

then using the base class operator+ is probably a good way

to implement the class.  If your derived class needs access to

the base class in a lot of methods, the going with protected

data is probably better.



And, of course, a third solution is to provide a set of protected

inlined mutator/accessors so that your derived class(es) have full

access to your base class data, but other classes do not.  This

is a lot more work, but a purist would probably take that as the

best solution.

I have realised, that the above line does not compile, so I came up with=20

[Dev-C++] operator+ and inheritance

[<or...@vp...>]

Hi!

I have a question regarding operator overloading and inheritance. I have=20
a base class with some data. And I also have a derived class from base,=20
which extends base with even more data. I have defined an operator+ for=20
the base.
My question is: how can I define an operator+ for the drived class, so=20
it will copy both the base and dervied data. Must I call the base=20
operator+ from the derived operator+ explicitly?
I have thought of something like this:

class Base
{
public:
	Base operator+( const Base& b )
	{
		Base sum;
	=09
		sum.m_BaseData1 =3D b.m_BaseData1 + m_BaseData1;
		sum.m_BaseData2 =3D b.m_BaseData2 + m_BaseData2;
	=09
		return sum;
	}

	int m_BaseData1;
	int m_BaseData2;

}; // Base

class Derived
{
public:
	Derived operator+( const Derived& d )
	{
		Derived sum;

		// assign "this + d" to sum:
		sum =3D Base::operator+( d );
		sum.m_DerivedData1 =3D d.m_DerivedData1 + m_DerivedData1;
		sum.m_DerivedData2 =3D d.m_DerivedData2 + m_DerivedData2;
	=09
		return sum;
	}

	int m_DerivedData1;
	int m_DerivedData2;

}; // Derived


Is that correct?
And if so, my next "problem" is, that an assignment operator needs to be=20
used in the Derived operator+. Can that be "solved" (removed) somehow?

Thanks in advance.

Re: [Dev-C++] system

[michele <mic...@li...>]

Thanks for your answer...
yes I'm sure, I try it even in very symple code:

#include <iostream>

int main(){
system("pause");
}

but probably the problem is of my antivirus (esafe desktop), because it stop
the application.
Althought if  I double-click on my ".exe" the problem disappear (i.e. the
program works right). This is strange, no?

[Dev-C++] file read / write issues in Win XP

[davelaw <da...@fo...>]

I am a C++ newbie - and new to Dev-C++. I'm running through Bruce Eckel's
TICPP2v1 exercises using a Win XP Home machine and Dev-C++ v4.9.8.7. I've set
up a the Path to my default working directory, and I can run my compiled
programs from the console without using the absolute path.  But my programs
won't read or write a file in my default directory, unless I use the entire
path. For example, I create a filetest.exe as follows, and the error msg
appears each time. But substituting the entire pathname fixes the problem.

#include <iostream>
#include <fstream>
#include <string>
using namespace std;

int main() {
    ifstream in("filetest.cpp");
    if (! in.is_open()) {
        cout << "Error opening file"; exit(1); }
    string s;
    s = " opened successfully";
    cout << in << s;
    return 0;
}

Did I miss a crucial setup setting in Dev-C++? Or is this a Win XP issue?

1) Stop placing a lot of code into a header file unless it is template
code.

2) The if before the switch has a { but no } so the compiler see you write
switch () {
} else {
}

and switch doesn't support any else statement.

Re: [Dev-C++] help!!! it's not a virus!!!

[Ewald H. <in...@ho...>]

Hi.

On line 53 of your winmain.cpp file you have the following code:

    while (GetMessage(&clockMsg, clockWin, 0, 0) !=3D 0)

changing it to

    while (GetMessage(&clockMsg, 0, 0, 0) !=3D 0)

has resolved the problem on my computer. Even after running clock.exe =
20x it doesn't show up in my taskmanager as a runaway application.

As for the second part of your question, I have never had the same =
problem, so I can't really answer it well. Processing WM_CLOSE does not =
seem to be important in most tutorials or courses, as they seldom hit =
the program size where you'd want to take special action in the event =
that someone closes a window.

I hope you get your app running.
