[Dev-C++] dll

[Noorez K. <coo...@ho...>]

for functions in dlls,  do I need to use the  __declspec (dllexport)  for 
both the declaration and definition of the function to compile the dll 
correctly or is it ok in just one place. If it's just one place where do I 
need it?

Your message displayed as white on white text, so many people probably
just assumed it was a blank message. Also, I don't think you mentioned
the portability issues of a system() statement, or that the console
works well too.

Re: [Dev-C++] unable to run hello world.cpp

[Eric <eri...@cl...>]

that's why I suggested
 at the end of the program ask for some useless variable.

Just a word of warning, this doesn't always work on some systems. It
will work perfectly on Windows and a lot of other operating systems, but
unless portability is your primary concern, you shouldn't have to worry.
You can also just run it from the DOS prompt, and it will not exit at
the end so you will have time to read the output.

Re: [Dev-C++] Three dots in function prototypes

[Per W. <pw...@ia...>]

A variable number of parameters.

The most common use is the printf() class of functions, where the
parameter immediately before the ellipsis (the three dots) is a formatting
string, specifying how many parameters that will follow, and of what
type they are.

However, you might write your own functions doing just about anything. An
example:

int int_sum(int count,...);
void vec_add(Vec& res,int count,...);

However, the use of an ellipsis is most useful when the individual "extra"
parameters have varying types, since the above two examples could have
been modified to have two parameters - a count and an array of
integer or Vec items.

The functions need to use the macros va_start(), va_arg(), and va_end() to
walk through the extra parameters. However, the function never know how
many parameters and of what type it has received. It is completely up to
he caller to adhere to expected behaviour.

Look at http://www.functionx.com/vcnet/libraries/win32dll.htm for a good

[Dev-C++] DLL Help Wanted!

[Jingles P. <jin...@ya...>]

Hello,

I've been working on a game for Dev-C++, and I'd like
to use a DLL. But I don't really know how, so I was
wondering if anybody here knows of any good Tutorial
or Information Sites that has stuff dealing with the
creation of DLLs.
I also wouldn't really mind if the site just has
Examples or anything, just some info on the Creation
of DLLs. Thanks.

[Dev-C++] code formatting

[<gen...@ya...>]

hey all,
this mainly concerns the developers of the Dev-C++
IDE. i was wondering if it would be possible to use
Scintilla (http://www.scintilla.org) as the text
component for the editor, instead of (what i think is)
a customised rich text field, since Scintilla provides
syntax highlighting already. it would be a major
change, but as Scintilla also formats your code as you
type, it might be worth it.

TIA
dype

Re: [Dev-C++] A question

[Scott S. <age...@co...>]

For learning C, there is The C Programming Language by K&R. Probably the 
best guide out there to C! Also, I would not recommend Sam's Teach 
Yourself C++ in.. books. You can/'t learn a language in 24 hours or even 
30 days. It takes a long time to learn a language. I have been working 
on C/C++ for about 1 3/4 years, and just now consider myself an 
intermediate programmer. Different people take different times though. 
Probably the only ones out there who can learn a language in a week are 
super hackers like ESR and Stallman. Anyways, The C++ Programming 
Language is a good book to have. It is written by Bjarne Stroustrup, 
creator of the C++ language. The special edition has a hard cover and a 
few new appendices, but costs more than the 3rd edition. However, if you 
flip through C++ books a lot, special edition will help. If you can get 
through Effective C++, you should be apply to get through The C++ 
Programming Language. Also, check out More Effective C++ by Scott Myers 
if you read the first.

Re: [Dev-C++] strage error

[Per W. <pw...@ia...>]

I haven't the time to discuss your stream problem - there are a _large_
number of questions and answers about buffering and switching between
input and output in the archives of this list. Anyway, a quick note: don't
mix stream input/output with FILE-based input/output. The two methods have
their own internal implementation - including input/output caching - and
don't know about each other.

However, I wanted to comment a bit about your class implementation.

1) You have a class where each object is > 5kB large.
2) Quiz::createQuestion() is not static, i.e. you need a Quiz object to
call this member function.
3) Quiz::createQuestion() creates a new Quiz object as autovariable, and
later returns it.

You should rewrite createQuestion to either work directly on itself (the
'this' object), or to be static and perform all work on a created object.

When passing a Quiz object as a parameter, you should pass it as a
reference, instead of as value. Your Quiz::writeQuestion() method requires
that a new Quiz object is created as parameter.

Note that objects - just as C structs - have size and making extra copies
of them requires more memory and a lot of copying of information between
the copies. In the C++ case, assignment operators, copy constructors etc
might contain a lot of code that gets run.

One other thing. You haven't written any constructor for the Quiz class.
It is almost alwas a good idea to write your own constructor, instead of
letting the compiler supply a default constructor.

A third thing. You have static variable 'type'. Why static? If the
information is needed for processing of the question, it should be a
non-static member of the Quiz class. Then the writeQuestion method don't
need 'type' as input parameter.

Obviously Quiz::writeQuestion shouldn't need a quiz, a type etc as input
parameters. Since Quiz::writeQuestion is a method of the Quiz class, it
should write out itself.

Subject: [Dev-C++] How to configure auto-indent?


I'm using Dev-C++ 4.9.9.0 (phenomenal product, by the way!) and have 
a question about the behavior of autoindent and how to adjust it. 
Maybe I'm just overlooking something, but...

First off, I'm using spaces, not tabs (although, I'd /prefer/ tabs, 
more below [1]), a tab size of 4, no SmartTabs, Autoindent enabled, 
cursor past EOL/EOF both disabled, trim trailing spaces enabled.

Let's say I have this :

        case WM_COMMAND:
        {

Right after the {, I hit Enter and the cursor goes down one line and 
over 4 spaces, out in "virtual space". If I type a character, the 
leading space is filled with spaces, as expected. If I backspace, and 
then tab over to the column of the opening brace and type a 
character, it appears in colum one and I have to "tab it over" to the 
right column.

Apparently, hitting Tab after an autoindent has taken place often 
doesn't insert anything into the file, tab or space. It just moves 
over in virtual space. Apparently there are two things at play here, 
maybe just something I don't understand, but - 1) tabs aren't 
(always) treated as whitespace and 2) the autoindent doesn't go where 
I'd /prefer/[2] it go.

Is there any way to modify this?

[1] I'd really rather use real tabs, with the value still at 4, but 
that causes the enhanced home key behavior to break, since apparently 
it doesn't see the tabs as whitespace over which to "cycle" (for lack 
of a better term). The cursor just sits on the first non-space 
character regardless of how many time you hit Home.

What I'd like is fairly simple -

1. Hitting Tab just inserts n (4 in my case) spaces (or preferably a 
real tab character) from the current column, adjusted to line up as 
you'd expect, backfilling to start-of-line if the cursor wasn't at 
column 1 when the Tab key was hit.

and...

2. Hitting Enter simply inserts a line and tabs the cursor over to 
the column of the first non-whitespace character on the line above.

That's all...

[2] I realize we all have preferences, which is why I'm looking for a 
way to customize this, rather than simply complain about it. :-)

OR --- Is there way to use an external editor? I know, that kinda 
defeats the purpose of an IDE, but I thought I'd at least ask...

Thanks!

Re: [Dev-C++] A Question of & use

[Roger F. <ra...@ha...>]

Aloha from Honolulu,

Kiryl,
   My original email had this:
 >>    First: in "Effective C++", item 15, p. 65:
 >>         "operator= default version C& C::operator=(const C&);"
 >> The & follows the variable (?).

I assumed the "C" following "C & C::operator=(const "
was the variable--somehow it must have got lost on you.  I understand 
const is a type def.
My major concern was with line 8 (below)
 >>         8:       CAT (const CAT &);    // copy constructor

But as Per W. pointed out in his reply on 8/24/04 8:49PM :
 >   int my_function(int &);
 > _doesn't_ have the & last, since there is an "invisible" :) parameter 
name

   That the var is invisible was the info I needed.
   Regarding "lhs" and "rhs", I was confused because "The Complete 
Reference C++" never seems to use them.  Perhaps he's keeping his code 
as simple as possible for clarity sake.  I continue to find his examples
