Hello all,
	I'm surprised that the graphics library Winbgim works less well with 
Dev-C++ 4.9.9.2 than with version 4.9.9.0 !

I have recently installed the GTK devpacks on devcpp. I can compile and run the example GTK programs from GTK + Book Examples and gtk2_examples,
but when I try to create a new GTK project I get the following error:

I'm trying your code snippet as a console application...
 
Suggestions:
I get a warning from <iostream.h>
D:/Dev-Cpp/include/c++/3.3.1/backward/backward_warning.h:32:2: warning: #warning This file includes at least one deprecated or antiquated header. Please consider using one of the 32 headers found in section 17.4.1.2 of the C++ standard. Examples include substituting the <X> header for the <X.h> header for C++ includes, or <sstream> instead of the deprecated header <strstream.h>. To disable this warning use -Wno-deprecated.
 
Use <iostream> instead.
 
However, the main issue is that at return 0; the command shell (console) automatically closes the window!  Try putting: 
system("PAUSE"); before the return.
 
using namespace std;
#include<iostream>
int main()
{
float height, diameter, volume, gallons;
cout << " Enter the diameter and the height of the cylinder " << endl;
cin >> diameter >> height;
volume = 3.1416 * (diameter/2) * (diameter/2) * height;
gallons = volume * 7.5;
cout << " The Volume of the given diameter and height is " << endl;
cout << diameter << "   " << height << "   " << volume << endl;
system("PAUSE");
return 0;
}

Works fine! Remember the seperators in the output and the endline, BTW, or you'll get one big line of stuff.

When i execute a program using Dev-C++ the program will not show the end result after entering input; it will just exit the display screen.  Why does this happen?

Take this program for example.....

  A. Establish the diameter of the tank in feet
  B. Establish the height of the liquid in the tank in feet

  A. Compute the diameter and height values in the formula for volume
     of a cylinder
  B. Volume of a cylinder is 3.1416*radius*radius*h
  C. Radius is the diameter/2
  D. The obtained volume is then converted to gallons

 III. Display the results
  A. Display the volume
  B. Format: The volume of the given diameter and height:
   "_' "_' etc. "is" the volume */

Sometimes you have to forcibly put the library line in the Build Options-->Parameters-->Linker window in the form of: ../Dev-Cpp/lib/libfltk.a or whatever your path is.  First try copying it to c:/dev-cpp/lib with it's original name, and if that doesn't work, then use the above form to force Dev-Cpp to link it.

For the record/archives, and all those who have asked before, and whom
venture back to ask again:

The following opportunity does exist and is well documented for those
who may be interested in learning/experimenting more about working
with QT:

The QT3/Windows Free Edition is a native win32 port of the gpl=B4ed
qt/x11 sources. It uses the native win32 api and does not require
cygwin.

Complete instructions for utilizing Dev-C++ as an alternative IDE and
frontend for coding QT3 apps can be found here:

"static" for a function means the same thing as "const" for a
variable. If you declare a function static, the compiler won't
let you give separate definitions for the function in
different source files.

By the way, C++ is case sensitive, so you need to type
"static" instead of "Static". Otherwise, you might get some
points taken off for this question.

> The Second:
> How can I overload the "<<" operator?
> Thanks,

You didn't mention what datatype you wanted to overload it
for, so I used a char*. It should be easy enough to convert
this method to use another datatype.

/*****************************************************/
char *overload(std::ostream &out, char *p) {
	return (char*)((unsigned)p << (unsigned)&out);
}

cout << overload(cout, "cheater");
/*****************************************************/

 From now on, though, you should probably do at least some of
your homework yourself.  I won't always have enough time to
help you.

From C/C++ Reference
"The static data type modifier is used to create permanent storage for variables. Static variables keep their value between function calls. When used in a class, all instantiations of that class share one copy of the variable."
 
<< can be overloaded via the operator keyword by:
void* operator << (whatever_gets_passed) {
...
}
 
As an example, in LeakTracer, new is overloaded as:
void* operator new(size_t size) {
 return leakTracer.registerAlloc(size,false);
}

Try the _findfirst/_findnext/_findclose set of functions.  I believe they allow regular expression searching.  I'm using them with both wildcard searches '*', '*.*', and with searches for a specific name.  It would be something like:

entrydir = getcwd(NULL, MAX_FOLDER_TEXT_SIZE);
chdir(startpoint_for_search);
if ((findhandle = _findfirst(search_string, &finddata)) == EOF) {
 // One wasn't found.
...
}
{ // Process a found one!
...
} while( (result = _findnext(findhandle, &finddata)) == 0 )
_findclose(findhandle);
chdir(entrydir);
free(entrydir);
 
You must close the find handle, always, and free the entrydir variable if you use the above form.  I use the above in recursive folder searching.

Always try finding that reference in the libraries via a text search, then insure that you are linking it in. I.e.
 
$ pushd (or cd) /yourPath/dev-cpp/lib
$ grep -r 'WSAStartup@8' *
Binary file libws2_32.a matches
Binary file libwsock32.a matches
 
$ grep -r 'socket@12' *
Binary file libws2_32.a matches
Binary file libwsock32.a matches
 
$ grep -r 'WSAGetLastError@0' *
Binary file libws2_32.a matches
Binary file libwsock32.a matches

Nothing necessarily.  Depends on where the breakpoint is set.  As an example, if I have a class constructor, and I set the breakpoint within the constructor, it is ignored.  If I set it at the instantiation of the class, then I can step into the class constructor.  Try setting a breakpoint at the line just before where you are actually interested in.
 
Another possibility is that the line isn't really being executed.  You may try adding the flag 
-Wunreachable-code to your compiler parameters just in case.  Otherwise single-step through the section that you think is being executed to verify that it is.
 
By instantiation I mean where you do
 
MYCLASS myClass;  (set the breakpoint there, and then (S)tep into the class) not in the declaration:
 
class MYCLASS {
...
};

reading and comparing filenames
Yeah, sounds simple enough. :-)  I don't know what you want us to help =
you with.  But, I would tell you, that I have done something like this, =
but I used the DOS command DIR (HELP DIR) to get my listings and pipe it =
to a file (DIR /options > filenames.txt).  It was easier since the dir =
command has many options for sorting, so you could get the list that you =
want and have the files be in the right order etc.  So, you could do a) =
and b) in one command. (Of course, depending what you really want in a) =
and in b).)  You could even run a few commands with a few files as input =
and then execute c) with the input gathered from a) and b).  Just a =

Hi Josh,
 
Thanks for the help!  Currently I'm doing class debugging by units, piece by bloody piece to find these insidious memory leaks!  This is recommended in Test Your Classes, a part of Just Say No To Memory Leaks.
 
I'm using LeakTracer for the leak test.  It's only downside its that it requires the Perl language to use effectively, though it isn't required for actual use.  Everything is commented out except the GUI class.  I've already verified that the GUI constructor/destructor has no leaks.  Just rechecked it, getting the report:
$ cat leak.out
# starting Thu Feb 24 22:59:03 2005
# memory overrun protection of 4 Bytes
# initializing new memory with 0xAA
# sweeping deleted memory with 0xEE
# aborts on OVERWRITE_MEMORY 
# not thread save; if you use threads, recompile with -DTHREAD_SAVE
# internal buffer now 32768
# finished Thu Feb 24 22:59:03 2005
# total allocation requests:      2 ; max. mem used 1 kBytes
# leak      0 Bytes     :-)
 
I've got these two macros to help:
#define zap(x) if (x) { delete(x); x = NULL; }
#define zap_array(x) if (x) { delete[](x); x = NULL;  }
 
In GUI class declaration, I'm declaring a public pointer to a FLTK text display buffer:
...
Fl_Text_Buffer *textbuffer; // Text widget buffer.
...
 
In the constructor I'm declaring:
...
zap( textbuffer )
textbuffer = new Fl_Text_Buffer(1024);
...
 
In the destructor I'm declaring:
...
zap( textbuffer );
...

In my make_window code I have (and I've put this all over the place, including trying it as a static declaration at the top of the module & not using the declaration in the class, in the make_window call, and in the constructor, which is it's current location.  Nothing changes other than the machine code address of the leak!):
 
void GUI::make_window ( const HINSTANCE hThisInstance ) {
...
statusTextDisplay = new Fl_Text_Display(100, 295, 270, 135, "File Cleaner Status/Results");
statusTextDisplay->buffer( textbuffer );
...
}
 
So I'm creating a pointer to a structure with new, and then I'm deleting it if that pointer isn't NULL.  Running the program, I have a 4 byte leak at 0x410E40 (among 4 others for a total leak of 68 bytes), which LeakTracer says isn't in my code.  Using Insight, it's reported as being D:/Dev-Cpp/include/c++/3.3.1/cmath, line 477.  Fine...
 
At the breakpoint I get the following:
Breakpoint 2, 0x00410e40 in Fl_Text_Buffer::add_predelete_callback(void (*)(int, int, void*), void*) () at D:/Dev-Cpp/include/c++/3.3.1/cmath:477
Current language:  auto; currently c++
 
With the stack trace being:
#0  0x00410e40 in Fl_Text_Buffer::add_predelete_callback(void (*)(int, int, void*), void*) () at D:/Dev-Cpp/include/c++/3.3.1/cmath:477

#4  0x004377ba in main () at D:/Dev-Cpp/include/c++/3.3.1/cmath:477
 
FileCleanerPro_Main.cpp:581 is statusTextDisplay->buffer( textbuffer );
FileCleanerPro_Main.cpp:794 is gui.make_window(hThisInstance);
 
This only occurs if I'm calling the code to make the window from WinMain:
...
gui.make_window(hThisInstance);
...
 
Everything else is commented out.  To test the constructor/destructor, I comment out the above line.  The instantiation of GUI is at the bottom of the module as GUI gui; and is declared in the header file as extern GUI gui;
 
My question is then WTF~&*#$!  I'll look over the site you link below, as I'm also in need of knowing how much memory is actually available for use before it goes to virtual memory.  The need is in the time difference between using fputc and fwrite.  fwrite is about 35% faster (I've run extensive tests on timing, as I'm doing a for-sale professional version of File Cleaner that uses multi-pass writes to files to effectuate unrecoverable wiping of data, even with magnetic force microscopy).  However the speed increase only occurs if you are actually doing writes to ram vs. hard disk.  I'm resorting to fputc and fwrite due to inconsistencies that I had using ofstream.  This application MUST flush to the hard disk every time, or else confidential and secure wiping (two modes of operation entailing 11 passes and 35 passes respectively) doesn't occur (other than in ram!).  ofstream wouldn't do that consistently.
 
Thanks for your time, everybody, and apologies for the length of this post.  I've spent 59+ hours on this so far without satisfactory solution.  I'm in need of a cigarette or of something much stronger to burn! ;^)

worked wonders for me. No changes required, just use normal
allocation techniques for C/C++ source code.
