Though this might seem spamish for newbies, this IS (was :D ) really 
serious. I truly recommend everyone to visit

for the latest news. You won't be disappointed :)

Greetings,
   Balázs

The program consumes an enormous amount of CPU, so other programs run so 
slow.

The first is that if you have compiled one project, modify one of its 
sources and then press compile (F9) it compiles the modified file, but 
when you press execute it says project not compiled, that if it doesn't 
show linker errors with the string class.
The second is that webupdate says it's disconnected or the server is 
down and so it cannot check for updates.

The nice thing about STLs is that they take care of all of the fiddly bits for
you.

I'm not sure that an STL container implementation is required to free up the
memory used by a deleted member.  Don't worry about it.

I don't think that you can dereference an iterator. Eliminate the line that
won't compile.  It's not needed.  The member is erased by the line:

resultTable.erase(xIter++);

but

Danger! Danger! If the container is a vector, string or deque, the iterator is
invalid after the erase.

It's too much to go into here.  For more information, see Item 9 in Scott
Meyer's Effective STL book.  Nicolai Josuttis' The C++ Standard Library would
also be a very good investment.

Reid, 

I got it working finally.  Thanks for all the help.  

This is all still new to me.  I am still having a small bit trouble
understanding friends and overloading operators, especially the use of
const.  Got any sites for me?

Thanks

Joseph

Reid,

That did it.  It's compiling and running, but for some reason the minutes
don't seem to be advancing.  It appears that clock.advance(15); is not
pushing my minutes up...I'm going to have to debug.

Thanks for the great assistance, but I'm afraid I really don't quite
understand everything that was going wrong???

Joseph

Hm... That's not so simple.
For dynamically allocated memory using the "new" operator or "malloc",
this can be done by:

Overriding the global operator new and adding the amount of bytes to a 
global variable. You also can override global operator delete to 
subtract the freed amount of bytes from that variable - that way you can 
check if all allocated memory has properly been freed before terminating 
your program.

If you use malloc(), write and use your own function, for example 
AppMalloc() and AppFree() and add/subtract the amount of bytes to a 
global variable.

There is no other way to do it in C/C++, as far as I know, and no 
Windows API function that can tell you how much RAM you're using.

Hope this helps!

It was there in Dev4.0, but now it has dissappeared.

I'm not getting the same errors... My errors do not say a line number and
only appear as such:

I'm still learning so please be patient.

I am running into some problems.  I've defined my interface file as
"compile.h", my implementation file as "compile.cpp", and my application
file as "main.cpp".  The implementation and application files both contain [
#include "compile.h" ].  However, when I try to compile my application file,
I receive numerous linker errors with undefined references to my class.

HELP!  

Am I not understanding the whole seperate file compilation?  Isn't the class
interface and implementation files supposed to be named the same and just
with different extensions?  

I've attached all three files...thanks.

Joe <<compile.cpp>>  <<compile.h>>  <<main.cpp>> 

How can I find out how much memory my program is using?
I'm running it under windows and was wondering if there's a Windows API call 
or some utility on the net that can latch on to my program and find out how 
much memory it is actually using.

If I'm not being specific enough, tell me.

Hi all
firstly thanks to Yeoh for the dev project files for the static library &
bgidemo (  http://www.yeohhs.com/shareware/winbgi_DevCpp.zip ) 
When I use the outtext() function & run on win2000 the text is in the colour
set by setcolor and the background colour is as set by setbkcolour as one
would expect, but if I rebuild & run it on a win98 machine the text colour
is OK but the background colour goes to black irrespective of what I set the
background colour to.
Does anyone have a fix or must I live with the performance difference
between the OS ?
P.S. I'm not familiar with windows API programming :-(

TIA
Mark

Simply change IsCpp=1 to IsCpp=0 (or vice versa) in 
NameOfYourProject.dev file

Sorry, I must have got brain-fever

It should be bit&7 not bit&3

Don't know where the 3 came from in the first example, but then I managed
to continue with it for the test_bit() and clear_bit() functions too...

Am I bad or just a bit tired :-)

The code I sent defined bit 0 as least significant bit of first char, and
bit 7 as most significant bit of first char.
If you want to reverse order of bits within a character, you can use

0x80 >> (bit&7)

Then you will allocate bits from high bit to low in each character.


Also, the bits are zero-relative. If you do set_bit(mybits,2) the relevant
character should contain binary value 00000100 (4 decimal) if you use the
bit order of my example, or 00100000 (32 decimal) if you use the reverse
bit order of (0x80 >> (bit&7)).

dev 4.9.8.1

When you start a new project you specify it as C or C++. Once the project
has been defined, is it possible to change it? There is not an option under
project options.
Thanks in advance

that was clear.

understood.

ok. with you.

everything seems clear to me now. but the out put of my current code,
will be:

mybits: 0000 0000 0000 0000
mybits: 0400 0000 0000 0000

this does mean that the first byte changed from

(bin) 00000000 to
(bin) 00000100

right?
this should be

(bin) 0100000
(hex) 40

since I changed the second bit of all, right?

somewhere I made a mistake, I know, but where?

Hi, ALL!

Strange problem with DEV-CPP 4.9.8.3.

I use precompiler directive #warning to comment
important points in code.
Dev-Cpp 4.9.8.3 makes bad makefile when #warning in used.

Test source code:
------------------------------------------
int main(int argc, char *argv[])
{
#warning "MyComment"
  return 0;
}
-------------------------------------------


built makefile
-------------------------------------------
# Project: Warn2Mak
# Makefile created by Dev-C++ 4.9.8.3

CPP  = g++.exe
CC   = gcc.exe
WINDRES = windres.exe
RES  =
OBJ  = main.o $(RES)
LINKOBJ  = main.o $(RES)
LIBS =  -L"D:/LANG/MinGW3001/lib"
INCS =  -I"D:/LANG/MinGW3001/include"
CXXINCS =  -I"D:/LANG/MinGW3001/include/c++"  -I"D:/LANG/MinGW3001/include"
BIN  = Warn2Mak.exe
CXXFLAGS = $(CXXINCS)
CFLAGS = $(INCS)

main.o: main.c  main.c:3:2: warning: #warning "MyComment"
 $(CC) -c main.c -o main.o $(CFLAGS)

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

I attach test project.

Any suggestions?
Thanks in advance
Collins

First:
sizeof(mybits) is just size of pointer - not size of the array in bytes or
bits.

mybits[bit/8] |=3D 1 << (bit&3);

isn't so complicated. Each character contains 8 bits. So by dividing bit
with 8, I get which character the bit is stored in.

bit&3 will use the 3 least significant bits for a numeric range of 0-7.

1 << (bit&3) will then access one of the 8 bits in the character.

char test_bit(const char* mybits,unsigned bit) {
    return (mybits[bit/8] | (1 << (bit&3))) !=3D 0;
}

char clear_bit(const char *mybits,unsigned bit) {
    mybits[bit/8] &=3D ~(1 << (bit&3));
}

Hello !

   thanks for the update, Collin. The URL is not available for me 
though. Maybe I should check back later.

hi Per,

I'll show you my code now. somehow it does not work as planned..

char *alloc_bits(unsigned int);
void set_bit(char*, unsigned int);

int main(int argc, char *argv[])
{
    char *mybits;
    
    mybits = alloc_bits(60);

    if (mybits) printf("bits[%d]: %X\n",sizeof(mybits), *mybits);

    if (mybits) set_bit(mybits,2);

    if (mybits) printf("bits[%d]: %X\n",sizeof(mybits), *mybits);

    system("PAUSE");
    return 0;
}

char *alloc_bits(unsigned int bits)
{
    return calloc(((bits+7)/8), sizeof(char));
}

void set_bit(char* bits,unsigned int bit)
{
    bits[bit/8] |= 1 << (bit&3);
}

what exactly does the set_bit() function do?
I don't understand it fully especially the (bit&3) part.
also I am totally lost in writing a get_bit() function..

any help appreciated!

Hello!


Thank You for Your answer. That makes me clear many things.

Ok, I see.

So is that mean, that the static library and the import library is same
regarding the names? How can I find out, if my libaaa.a is static or
import library? (from the size?)

No, it is not bulit by me.

It is not secret, the libraries is the glut and the fmod. As far as I
know, these are free and also the source code is available. Now, I tried
to compile both of them with dev-c++ without result. (Even nor dynamic nor
static library couldn't be create)

Hi guys,

I've ran into a small problem here...
What I'm trying to do is to iterate through an STL data structure. On a =
successful match in criteria, I wish to delete the iterator and its =
contents away from the memory. However, when I attempted to call delete =
on the node that I want to remove, the compilation throws an error. =
Anyone knows what's going on? Here's the code for your reference:

for (ResultTable::iterator xIter=3DresultTable.begin(); =
xIter!=3DresultTable.end(); ) {
        if (!matchFound) {
                // Match was unsuccessfull
                // TODO:
                //      Free memory allocated to this node
                    delete(*xIter); // Compilation fails at this point
                    resultTable.erase(xIter++);
        }
        else {
                // Match was successful begin copying the additional =
columns=20
                // over from y
                    ++xIter;
        }
}

Thanks and regards,
Ed

The .dev file can be opened and edited with a text editor. It will =
contain the reference to the old read_level.c file.=20

BUT the SAFEST way to deal with this problem is to:=20
1) in Windows explorer copy the file draw_level.c to a file called =
read_level.c
2) open the project in DevC++ - it should now open OK because it will =
see read_level.c
3) remove read_level.c from the project=20
4) add the file draw_level.c to the project=20
5) confirm all is OK and close the project=20
6) from Windows explorer delete the read_level.c file you created in 1) =
above. You won't need it now.=20

This should fix it.=20

The reasons why using a text editor to change the reference to =
read_level.c in the .dev file is not recommended is that a) any mistake =
will cause DevC++ to reject the .dev file, and b) DevC++ writes a time =
stamp to each file in the .dev file to tell if the files have been =
changed since DevC++ last had them open - I don't know how to ensure =
this time stamp is correctly set.=20

Hope this helps.=20

Subject: [Dev-C++] hello and .dev files


Hello!

 first question to the list;

i'm wondering;
i re-named one of my .c files in a project to draw_level.c from =
read_level.c
but when i open
the project i get cannot find read_level.c . Obviously Dev-C's looking
for read_level.c not draw_level.c

 is there a way to access the .dev file
to change what files it looks 4?
(assuming this is when the info on what files the project's made of is
kept).

thanks for any help,

william
