[Dev-C++] Opengl Question

[Ian W. <lak...@ho...>]

USING GLUT...


hello people. i have two quick questions about opengl:

1) i know how to load a single texture and apply it to a 3D object, but does 
anybody know how to load two textures and apply them to different surfaces?

2) is there a way of displaying text when using opengl. e.g. like the frame 
rate in the top corner?

thankyou in advance to anybody that can help.

Re: [Dev-C++] linked list as stack

[Jason H. <jas...@bt...>]

Why is your pop method wrong? I don't really understand why using a node
would be a problem. I assume that you are refering to the node pointer? The
only problem that I can see (at first look) is that initialize doesn't
delete any pointers that may be stored in the stack, but just discards them.
That would be a memory leak.

To use the stack all you need to do is declare an object of stacktype and
call it's members in the usual fasion.

//........... At top of code with other includes
#include "StackHeader.h"

//........... in code body

stacktype MyS;

// push some values onto stack
MyS.push(10);
for(int v = 0; v < 100; v += 5) MyS.push(v);

display(MyS);

add(MyS);

// pop off top value
int x = MyS.pop();

cout << "The value is: " << x << endl;

This code doesn't do anything in particular, it's just a demo.

If I have missed the point please try to explain in a little more detail.

Jason.

[Dev-C++] linked list as stack

[chromatonus 7. <chr...@ho...>]

hi, I was given the following header (can't change it, sorry) to write a 
calculator prgm using linked lists as stack (reverse polish notation or 
postfix)

#include <iostream.h>
#include <conio.h>

struct node
{
   int data;

      //			and will set screen row to initial value
      void initialize();
  	  //	postcondition:	object stack list is set to NULL
      //				the screen display is cleared
      bool is_empty();
  	  //	postcondition:	return FALSE if stack = NULL otherwise
      //				return TRUE

      void push( int );
      //	postcondition:	the entered data value will be placed at the HEAD

[Dev-C++] libraries

Another problem:
How can I create a library (.a) with DEV-Cpp?
Somebody could tell me where I can find a tool which converts the .lib in .a
?
Thanks a lot.

Re: [Dev-C++] more problems compiling classes and libraries

[Luigi S. <gi...@li...>]

Hi

Here I'll attempt to give you a possible explanation of the error messages 
that you get.

I hope to make my explanation clearer by writing a trivial version of your 
program.

dynarray.hpp                  dynarray.cpp
-------------------------     -------------------------
#ifndef dynarray_hpp          #include "dynarray.hpp"
#define dynarray_hpp          ////////////////////////////
                               DynArray::DynArray(int size)
class DynArray                {
{                                 n = size;
    int n;     // size             p = new double[n];
    double *p; // memory       }

public:                       ////////////////////////////
    DynArray(int);             DynArray::~DynArray()
    ~DynArray();               {
}                                delete[] p;
#endif                        }
-------------------------     -------------------------

main.cpp
-------------------------
#include "dynarray.hpp"
int
main()
{
    DynArray a(3);
    ...
}

dynarray.hpp is an header file, it will be included, by a source file, when 
the class DynArray is used by code placed in the source file (in fact it is 
included by dynarray.cpp that defines the functions of the class and by 
main.cpp that uses the class).


Probably your version of the class DynArray looks like this:

dynarray.hpp                  dynarray.cpp
-------------------------     -------------------------
#ifndef dynarray_hpp          #include "dynarray.hpp"
#define dynarray_hpp          ////////////////////////////
                               DynArray::~DynArray()
class DynArray                {
{                               delete[] p;
    int n;     // size         }
    double *p; // memory       -------------------------

public:
    DynArray(int);
    ~DynArray();
}
#endif

////////////////////////////
DynArray::DynArray(int size)
{
    n = size;
    p = new double[n];
}
-------------------------

As you can see, in this case a definition of the constructor is found in 
all the files that include the header file; in your program that means: one 
definition in dynarray.cpp and one in main.cpp.

If you only compile the source files, you will get no error, the problem 
arises when you attempt to build the binary file, in fact the linker will 
find 2 definitions of the constructor: one in the object file created 
compiling dynarray.cpp (dynarray.o) and one in the object file created from 
main.cpp (main.o), since it knows that there must be only one definition, 
it will point out the error.

A way to avoid the error, still keeping the definition of the constructor 
in the header file, is to turn the constructor in an inline function: I 
prefer to do so by placing the definition inside the class declaration, 
instead of using the "inline" reserved word (but that is a question of 
taste); so I would have written:

dynarray.hpp                  dynarray.cpp
-------------------------     -------------------------
#ifndef dynarray_hpp          #include "dynarray.hpp"
#define dynarray_hpp          ////////////////////////////
                               DynArray::~DynArray()
class DynArray                {
{                               delete[] p;
    int n;     // size         }
    double *p; // memory       -------------------------

[Dev-C++] creating/handling binary files

[mak <ma...@pu...>]

this is how to create a binary file in c(of course you can use it in c++)
#include <stdio.h>

FILE * filenum;       //pointer to file
filenum=fopen("External file name","mode")        
mode:r,w or a, read write,or appending
right after r,w or a type  'b' to open the file as binary
for example to create a binary file called my.dat write
FILE * f1;
f1=fopen("my.dat ","wb");
now to read and write to the file,you will use the functions
fread(buffer,siz,num,filenum);
which will read num values(of size siz)  from the filenum file and store it
in the proper array  named buffer.if a zero value is returned it means that
you have come to the end of the file.
to write you will use
fwrite(buffer,siz,num,filenum);
as above except that if the function returns the number of values written
to the file.
to seek values in the file use the function
fseek(filenum,(long)no_bytes,position);
the internal acces pointer of the file filenum will move no_bytes from
position.
position:0 start of file
1:current position
2:end of file

that's all. hope that helped

RE: [Dev-C++] creating files

[Ramana K. <ra...@my...>]

I know how to save to binary, which doesn't look like text if opened in
notepad or something:
#include <fstream.h>
...
int anumber = 17;
char letters[7] = "hello!";

ofstream fout("path of file");

fout.write((char*) &anumber, sizeof anumber);
fout.write((char*) &letters, sizeof letters);
fout.close()
//to retrieve data
ifstream fin("path of file");
int savednumber;
fin.read((char*) &savednumber, sizeof savednumber);
...

that's the basic principle for it, it worked for me, and some things might
not be necessary (like the (char*) for letters), I'm not sure, but including
it shouldn't hurt.
You also might need to include stdlib.h if it doesn't work

[Dev-C++] Dev-C++ DLL

[Ben C. <cra...@ya...>]

Hi list,

I'm new here, but I have one question, when you get
Dev-C++ to create a DLL for you, how do you use it? I
want to pass information from a MapBasic program to a
C++ DLL. Now that I've created the DLL in c++ and can
call it from MapBasic where do I put the code that I
want it use on the incoming data? Sounds like stupid
question but I'm very new to DLL's and am trying to
get a test version to work. I want to send a number to
the c++ dll and mess with it, then return it for
output in mapbasic. Any/all help would be great. If a
dll is the wrong method for doing this, anyone know
how else I can pass a value, or values(array) to a c++
program to alter/mess with it?

Thanx 
Ben

[Dev-C++] Problem with debugging

[Jazzboy <Ja...@pa...>]

Hi ,

I find dev-cpp a good program ,but I've been unaible to use the debugger =
of it.=20
Can somebody give me an example of how I could use it, because the help =
files don't help me.
Thank You

[Dev-C++] RE: char to int

[Jazzboy <Ja...@pa...>]

There is a simple fuctie from C atof(char) that converts a char to a =
float
You have the same kind of function but atoi(char) that converts a char =
to an int

[Dev-C++] Thanks for the help about length of AnsiString

[Anders N. <a.n...@de...>]

Thanks for the help about the length of AnsiString. Yes, I ment the =
AnsiString in C++Builder.

Re: [Dev-C++] Length of AnsiString

[Kevin W. <ke...@me...>]

Are you talking about a Borland-type Ansi String?
For that you use
book.Length();

Hello!

I create an AnsiString and "fill" it with a text.

Code:
    AnsiString book;
    book = EditText->Text;

How can I find out the length of the string book?

Quite right, my mistake. It needs a char pointer
