dev-cpp-users Mailing List for Dev-C++ (Page 2)

Hi ! I've just read the FAQ on bloodshed.net for Dev-C++. 
It explains the right syntax for including asm in C++ source code. But as I 
don't know the assembly language, it wasn't very helpful to me.
I'd like to do a graphic interrupt (13h for example). Can someone tell me the 
correct syntax to launch an interrupt ? how to do this ?

How can I get my getch function to work?  I keep receiving the errror =
"implicit declaration of function `int getchar(...)".

Hi:
 
I am new to Dev-C++.  Sometimes I get "Out of Memory" errors when I try to
close windows in a project.  The file does not have to have a lot of code in
it.  In fact the file can be empty and produce the problem.  Has anybody
encountered this?  If so, is there a remedy?
 
Thanks!
 
 

Well you may use the timeticks as described in an email before -

but you will have to integrate several ticks in order to get a clear 
value :

I would reset a frames counter to zero and save the number of ticks
into startticks

then wait at least 100 frames - and read the ticks counter
and store a new starttickvalue

FPS =3D 100 *1000 * 10 / (newtickvalue - starttickvalue)

100 frames * 1000 millis * 10 accuracy factor

why do i explain this easy math ? - well

100 frames should be used for precision / accuracy :

windows reports not the real ticks - but a difference of some 
milliseoncs. taking only the ticks between one frame would lead to 
inacurate values.

100 is a good choice / compromise bettween accurr. and speed.

if your app leads to nuch less then 100 frames per second - the 
value might be reduced -

try to obtain at least around 1000 ticks

after having calculate a new actual FPS value , perform a 
smoothing :

average =3D average - (average >> 2) + (newvalue >> 2)

where 2 or more (up to eg 5) increases smoothing


after this



oldvalue =3D oldvalue - (oldvalue >> 2) + (newvalue >> 2)

 value 2 above is dynamic hysteresis and avoids toggling
(might be up to  4, where larger means quicker !!!)


if ((average > (oldvalue + 4) or (average < (oldvalue - 4) )-> 
	oldvalue =3D average;
	screenupdate using average / 10;


 value 2 above is static hysteresis and avoids toggling
(might be up to  4, where smaller means quicker)


remember :

value avarage / 10 ist the real FPS -> see accuracy factor

Hi,

This is a snippett of code I have written in the past. It was written for 
HPUX 10.20 so there may be slight variations in your Windows example.

Just ignore the #define stuff.

#include <time.h>

# define LG_COUT_TIMED(streamExpr) \
  do { \
    const int DATE_LEN = 100; \
    time_t t; \
    tm tm_s; \
    char date [DATE_LEN]; \
    if ((time (&t) != (time_t) -1) && (localtime_r(&t, &tm_s) == 0)) \
    { \
      strftime (date, DATE_LEN, "%c", &tm_s); \
      cout << date << " : "; \
    } \
    cout << streamExpr << endl; \
  } while (false)

Hello i used the method shown in the example hello to print into a 
windows -

but i did not succeed in placing variables there !

I also could not print at another point of the programm -
somehow the window is not updated (allthough i induced this)

------

a second question would be - howto place a variables value and 
also normal text into a grafik screen -
i used the open gl app to turn it into my desired prog.
all works fine but i do not know, how to place a text
(some explanations) and running vaklues into it.

any help ?
example code ?

sorry i cannot help you in this -  but i made the same experiences :

sometimes the textcolour works the wrong way  -
even if i set every text individually before .

one thing i recognized is, that text, which is allready on the screen -
printed to correct way !-  suddenly changes colour the next time -
becaus of another text fragment having a different colour
(somehow the console emulation must have caused this)

i also discovered problems with goto(x,y) -

it mostly works - but sometimes the is a miscalculation - however.

in one case i had to place the cursor with goto(x,y) and the perform 
a char 13 return to get into the desired line -
from this point on the next gotoxy work !

file02.cpp needs to know about function bob which is defined in file
file02.cpp. However it is much better practice to #include header files, the
header files will then include the prototype of the functions that you wish
to call hence:

main.cpp:
#include "file02.hpp"
// Note don't need to include file01.hpp because this file only uses weird
void main(void)
{
weird(); //works Ok :/
}

file01.hpp:
void bob(void);
file02.cpp:
void weird(void);

file01.cpp:
#include "file01.hpp"
void bob(void)
{
blabla
}


file02.cpp:
#include "file01.hpp"
#include "file02.hpp"
// Need to include file02.hpp because of the call to bob.
void weird(void)
{
bob(void) //isn't working!
}


Hope that helps. Once you get that working you might want to consider using
pre-processor directives to conditionally include a header file these are
useful to avoid declaring the contents of a header file more than once in a
programme and follow a standard template:

#ifndef __FILE01_HPP__
#define __FILE01_HPP__

// include the header file declarations here

#endif

Cheers,

    Graeme.

hi,

if i iunderstand you right, you should use header files.

basically, the function 'bob' which you call from within file02 has to =
be declared in file02. a declaration is just the function head and a =
terminating semicolon, i. e.

  void bob(void);

in your file02, before you first use bob().

but when function 'bob' along with other functions from file01 is used =
in many files, that's much work. on the other hand, you cannot include =
file01 in file02, because file01 would then be included twice in =
main.cpp.

so you should create a header file for 'file01.cpp', name it 'file01.h' =
and include it in every file that uses things from file01.cpp:

file01.h:

  blabla
  void bob(void);  // declaration
  blabla

file02.cpp:

  blabla
  #include "file01.h"
  blabla
  bob();

if you use this mechanism (.h / .cpp), you should, maybe later, also use =
it in your main.cpp.

hope i could help you.

Hi all!

I having serious problems with my projects... I would like to split my code
up into some different files, to make it more ease to navigate. But, when I
put functions all around different files, they cant call eachother, if that
makes any sense.

Example:

main.cpp:

#include "file01.cpp"
#include "file02.cpp"
void main(void)
{
	wierd(); //works Ok :/
}

file01.cpp:
void bob(void)
{
	blabla
}


file02.cpp:
void wierd(void)
{
	bob(void) //isn't working!
}


And the files ARE include to my project, and everything seems to be right,
but it isn't working for me... what's wrong??

Thanks! :)

Hi friends,
I am having Dev C++ version 4 installed .
I have tried to create a Window with menu items
using Dev C++ but failed.
I have sought help through this mailing list to get advise for =
rectifying the compiler error., but no result..
Can any body help me by  sending a sample, tested code
for creating a window with File menu, menu items Open,Save and  Exit, =
which compiles in Dev C++ version 4.
I like Dev C++, in all other respect but could not  create a=20
Window menu using this.

Even the NeHe tutorials reference DirectX so it probably is a good idea =
to have some knowledge of it if you are going to write some Windoze =

Here is a site that will show you how to get Dev-C++ to compile DirectX =

The solution of Anton Tichawa is right, but you can use the standard
function "time" that is independent from the platform.
eg.

#include <time.h>

int main(int argc, char **argv)
{
    time_t start, end;
    start = time(0);
    my_algorithm();
    end = time(0);
    // end - start is the number of seconds to run the my_algorithm();
}

----------------------------------------------------------------------------

then programming must be the process of putting them in.
----------------------------------------------------------------------------

hi, Urmila

calculating the time of an algorithm can be difficult and also depends =
on the hardware and software environment. but you can measure the time =
using a system clock, for example under Win32:

  int started;
  int runtime;

  started =3D GetTickCount();  // started =3D milliseconds since win was =
started
  my_algorithm();
  runtime =3D GetTickCount() - started;

now 'runtime' holds the number of milliseconds elapsed. if the =
resolution is poor, just call 'my_algorithm' many times:

  int started;
  int runtime;

  started =3D GetTickCount();  // started =3D milliseconds since win was =
started
  for (int i =3D 0; i < 1000000; i++) my_algorithm();
  runtime =3D GetTickCount() - started;

hope this could help.

anton tichawa.

Sorry!  Why don't you try OpenGL?  It's better because few modifications =
can make the code portable to other systems.  There you should start =
with NeHe's tutorials: http://nehe.gamedev.net or visit Nate @ =20
 http://nate.scuzzy.net/gltut/.  Also look for GLUT if you like this =
idea of portability!
Cheers,
St0fF.

Dear Dev-C++ users,

I'm trying to build a DLL to use with other applications made in Delphi =
and VB.
The code below is a very simple DLL I tried to make using Dev-C++.

It compiles perfectly and creates the DLL file.
But appears the warning: "no export definition file provided; dllwrap =
will create one, but may not be what you want".
I noticed that it uses the file "dll.def" and modifies the name of the =
function in the DLL to "TimesTwo__Fi".

I created a .DEF file, which is below, that I wanted the linker to use. =
How could be this possible?
Does anyone have a simple DLL made with Dev-C++, in C language?

Thanks in advance,

Rodrigo Hjort
