[Dev-C++] common questions

[Bjorn T. <bjo...@ho...>]

Some questions (like general question about DirectX, DLL, Windows 
programming and assembly programming tutorials) seem to come over and over 
again. It is natural since the subjects are very exciting, but perhaps it is 
a little inefficient for you to type basically the same answers several 
times.

My question is: Would be possible to create some sort of mail-list FAQ with 
relevant links to good tutorials? When someone finds a good tutorial it 
could be submitted directly to the FAQ.

The mail-list archive serves this purpose to some extent, but it is too 
difficult to find the general answers among the more specific "what's wrong 
with my code" etc.

Best regards
Björn Terelius

The Package Manager has no ability to add packages, only to remove them.
Once again, how do I add a DevPak to dev-cpp ? Double-clicking doesn't do it
so there must be a way.

RE: [Dev-C++] Timing My Application

[Ioannis V. <iv...@em...>]

There is not any CLK_TCK as part of any C or C++ standard. You are probably
refering to CLOCKS_PER_SEC.

After a search on the web I came up to this:


http://www.lysator.liu.se/c/c-errata.html


Check your macro name there.


My Greek K&R 2 has it correctly.

Re: [Dev-C++] Auto-indent

[Vesa-Matti <bo...@mb...>]

To my previous question.
There=B4s a checkbox labeled Auto Indent in the Tools>>Editor options
menu, but checking it doesn=B4t seem to have any effect. Currently the =
IDE
only prints everything to the same column regardless of curly brackets
and everything.

RE: [Dev-C++] Reverse Map lookup.

[Ioannis V. <iv...@em...>]

One thing to not be confused in my example. The unsigned keys i am storing
are sequential, that is 1,2,3,... that's why the
map<unsigned,double>::size_type is used from 1 to <=.size(). I could have
used an unsigned counter too. 

I am telling this so as to avoid possible newbie confusion, there is no
separate access through a size_type. size_types are unsigned integer values
used to describe the size (at least for usual containers, one can always
define his own size_type and size() to describe what he imagines as "size"
in his own classes. :-) ).

Re: [Dev-C++] Timing My Application

[Tony M. <to...@ho...>]

 From the Jargon File:

tick n.

1. A jiffy (sense 1). 2. In simulations, the discrete unit of time that passes between iterations of the simulation mechanism. In AI applications, this amount of time is often left unspecified, since the only constraint of interest is the ordering of events. This sort of AI simulation is often pejoratively referred to as `tick-tick-tick' simulation, especially when the issue of simultaneity of events with long, independent chains of causes is handwaved. 3. In the FORTH language, a single quote character.

Cool.

The only thing I was planning on using was the [] so I
could access the function pointers in the first map
easily
(will do this more often, the reverse look-up will only
be
used by admin functions setting up the connection between
command name and function pointer)

Re: [Dev-C++] Timing My Application

Maybe I can do a little better.

clock in time.h returns the number of CPU clock 'ticks'
since the process started. Combine that with the macro
CLK_TCK which gives you the number of ticks per second you
can get the most accurate timer that your processor can
handle. And best of all it is ANSI compliant.

multimap for more than 1:1.

Yes. There is a std::multimap.

If you are not very time concerned (I am using maps in this style myself =
and
haven't found it to be very slow) you can use a loop to check each one =
of
the addresses. Look what I am doing in a program of mine:


 map<unsigned, double> al;
=20
  // Ls sorted
 vector<double>L;

// ...


The double are floating point numbers, the same in both cases. In L they =
are
sorted though:


for(vector<unsigned>::size_type i=3D0; i<E.size(); ++i)
 {
 	for(vector<unsigned>::size_type j=3D0; j<A[i].size(); ++j)
  	{
 		al[ A[i][j] ]=3D something;

 		L.push_back(al[ A[i][j] ]);
 	}
 }



sort(L.begin(), L.end());


 system("cls");
=20

=20
 for(map<unsigned, double>::size_type i=3D1; i<=3Dal.size(); ++i)
 {
 	cout<<i<<": "<<al[i]<<"\t\t\t";
  =20
   cout<<L[i-1]<<": ";
  =20
   for(map<unsigned, double>::size_type j=3D1; j<=3Dal.size(); ++j)
   {
   	if(L[i-1]=3D=3Dal[j])
   	{
   	  cout<<j<<endl;
   	  break;
   	}
   }

 }



Check the last for loop inside the same for  loop. I search the value =
L[i-1]
(sorted vector) inside the map and display the unsigned corresponding to =
it.
It doesn't take long.


If you can't afford it, then you will have to use a multimap and a map =
and
keep them synchronized. I do not see any need to overload anything =
though.

[Dev-C++] Auto-indent

[Vesa-Matti <bo...@mb...>]

Can Dev-C++ automatically indent the code?
If it can, how it can be enabled/configured?

Re: [Dev-C++] DevPak

[<sol...@ya...>]

I anser only to the first part.
It happens to me the same, I use win2k, too, what you shall do is run 
the package manager, which is in the folder of dev (say C:\Dev-Cpp\), 
and under the tools menu.

[Dev-C++] Reverse Map lookup.

[David M. <ci...@ya...>]

Ok, here is a question for all you STL users out there.

I have a map which uses a string as the key and the data
object is a function pointer (I am yet to implement this so
don't ask me how I did it). What I would need (please don't
ask me why, it is the request of another member of our
team) but I also need to do a reverse-lookup (for a given
function pointer address what strings are assigned).

For the curious this is for a dynamic command system. When
the user enters a command we look up what function is
assigned to that command. For now you can assume that it is
a 1:1 relationship, no more than one command is mapped to a
particular function. This might change in the future
(should we start implementing aliases) so a solution that
would solve this as well would be quite helpful.

So far the only solutions I see is to set up 2 maps (2nd
one for the reverse lookup would have to be a multimap if
more than one command can be mapped to a particular
function). To make sure everything is kept in sync I would
probably have to encapsulate it and over-ride some
operators.

Thanks in advance

[Dev-C++] DevPak

[Edward D. <eld...@ea...>]

The instructions for installing a DevPak are to double-click on the =
file. When I do that win2K says that there is no program associated with =
the DevPak extension. Picking DevCpp ( C and C++ IDE ) just opens the =
file in the DevCpp editor. How do I install a DevPak ?

Also, while I am at it, if there is an update to a DevPak which is not =

[Dev-C++] diffsize

[Neszt T. <ne...@ss...>]

Hello!

It is a normal effect, that the Dev-C++ 4, complies different file size on
different processor (AMD, P4), when all other settings are same? (Project
options, source)


Thanks Your help in advance.

RE: [Dev-C++] Portable End-of-Line

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

When a file/stream is opened in text mode, the eol sequence is always \n
and then the underlying subsystem will perform the mapping to/from the
native format.

Notethat the underlying subsystem assumes that any read files are in the
native format, and might be confused if the file isn't. Most (all?)
dos/win libraries supports reading of both unix and dos/win files, but a
number of them gets confused for Mac files.

When reading in binary mode:
DOS/Win:	\r\n
Unix:		\n
Mac:		\r
Unicode:	U+2028

"\n\r" also applies at least to .NET text boxes.


In any case only '\n' is portable.

From my limited experience those "\n\r" etc sequences apply only to GUI
programs.

Any way, about line change since '\n' exists in all cases you can detect =
it
by reading character by character. If you want to display it consider it =
as
a system extension and you can handle it as all system extensions by
encapsulating it to a small portion of your program:


Example:

// Unportable encapsulations
namespace uenc
{
 const string eol=3D"\n";

 inline void clearscr()
 {
   system("cls");
  }

 // ...
}


So when you want to compile the program in another platform you have =
only to
change those encapsulations.


And try to forget the ancient C style stuff where C++ provides superior
alternatives.

[Dev-C++] Portable End-of-Line

[David M. <ci...@ya...>]

Is there a portable way of finding out the end-of line
sequence for the
current operating system? I hope to make my program
portable to both Win +
*NIX and would like something more (what word could go
here?) than:

#ifdef WIN32
  const char DIR_SEP = '\\';
  const char eoln[]  = "\n";
#else
  const char DIR_SEP = '/';
  const char eoln[]  = "\n\r";
#endif

Same applies to the directory separator. Is there a way I
can detect which
one is used? As I said portability is of utmost importance
so it must be C++
ANSI compliant (my program uses classes so it cant be a C
compliant program.

Hi,

We are working on it, through a new site for Dev-C++. Hopefully we should 
finish it soon :)

[Dev-C++] strange screensaver problem

[andreithomaz <and...@bo...>]

hello list,

with to the help of some members of this list, and of some friends of 
mine, I got to finish the screensaver that generates and solves a maze. 
But now there is another problem: it works fine in fullscreen but, when 
a fraction of it is shown in the "Control Panel->Video" (my Windows is 
in Portuguese, so maybe it is "Control Pane->Screen", I don't know), it 
crashes if it starts three times.

Has anybody had this problem in the past? I tried some changes in the 
way that  memory allocation is done, but nothing worked...

the code, and the screensaver, is in
http://www.civitas.lelic.ufrgs.br/andrei/dedalo_ariadne1.zip

thank you,
andrei

RE: [Dev-C++] IDC_NUMBER, windows programming

[Abhijit S. <mu...@gm...>]

Have you actually #include'd main.h from resource.h? If not, try including
it. If it gives errors, move all the resource-related defines into a
separate file (usually with an extention .rh) and included it in both the
main header and resource file. It would be a good idea to make the rh file
re-entrant using this technique:

-- start file `foo.rh' --

#ifndef _FOO_RH
#define _FOO_RH

#define IDC_NUMBER 610

#endif // _FOO_RH

-- stop file `foo.h' --

If you understand how a pre-processor works, this should make sense. The
_FOO_RH is only convention (generated from the filename). You can name it
anyway you like, as long as it doesn't conflict with any other macros.

HTH.

Why not start an open-source project, create a website for it, and announce
it on Freshmeat? Please don't post complete source-code for the program, as
you update it, here. It can eat up a lot of bandwidth over time. Besides,
this mailing-list is not intended for that. At the very least, upload it to
a site and post the URL, along with a text of changes, here. Also, posting
it to a site will give it greater exposure to web-search engines, so more
people can benefit from your code, rather than only the handful of C++
programmers who are subscribed to this list.
