dev-cpp-users Mailing List for Dev-C++

I would thank the members for giving expert suggestions and advice
concerning the public domain IDE Compiler Dev-cpp C++. I wrote to the
three design and developers of this system. Like a lot of many C++
programmers I am comfortable with Borland Compilers and IDE platforms and
miss some of the good attributes which should have been incorporated into
this Dev-cpp IDE. I am not sure why they had to re-invent the wheel and
use another batch of include library files. Also the merry go round one
has to fathom out to get a final presentaion on the screen. As I point
out later Borland has a drop down menu which  include ' User Screen' to
see the result of our code. I am not the greatest programmer in fact I am
a hardware engineer but intrigued with all the facets of C++ . This is
the inputs I wrote to the three desiners of the ID. Don't understand how
they came up with the name seen enough of that on the telly.
                   
  ' Copy of e-mail-Start :
Gentlemen thank you for an excellent job 0n the developement and design
of the Dev-C++ IDE/Compiler et al.However  a few points should be
addressed to make the IDE more useable for the public. Understand that
the design was based on the new standard ANSI/ISO C/C++ and also to
address different cross platforms Linux etc. THe IDE is very versatile
and functional except that there is no button or drop down menu whatever
which will allow the user to look at the output. Example Borland IDE's
has a separate drop down menu, when you click on 'User Screen' voila up
comes the result and output to the screen.One must innovate ,conjure up
go around to implement this feature. I have tried several 'A pause
statement , function getchar() there are no doubt other means of beating
around the bush. For instance in Borland I used  a one liner getche() in
my Blank file so I did not have to do anything to the program . At the
end of writing the code and compiling, run output came up on the screen.
                         May I suggest that this should have been an
integral part of the IDE design. Using the ' pause' work around incurrs
penalties and cross platform problems.
                            In the Question & Answer section the CLEAR
Screen command was brought up and you suggested we include Conio.c in the
Dev-C++ System File. I suggest the 'Clear Screen' function should been
activated with it's own Include header file. Now it could be there is a
file already for this manoeuvre, if so I get 50 lashes.
                          In your help files you go to great lengths to
explain all about 'C' programming and it's very well done . However most
of us have moved on to C++ and perhaps it  would have been prudent to at
least write some examples of C++ code. Just to introduce the newcomer to
differences due to ANSI/ISO changes and implementing the code with the
Dev-C++ IDE.
                           Finally Linux is continually mentioned as
though they had a stake in the company. This system you explain is the
reason so many things were changed causing us Borland user added work.
Considering the percentage of LInux users it seems to me as though we
should have put that at the back of the burner. Would like a response to
these concerns with the public interest in mind . End of e-mail.
                            If we are going to use an IDE and this one
seems to measure up and it's free then let's get it right .

hello,
It seems there are a lot of "pure C" fans here. However, I think the problem 
is not C++ itself. If you are dealing with complex and serious projects, you 
need the high-level facilities, and I think it is better to rely on the 
language itself than on "customized" libraries that are so often buggy, 
non-portable and badly implemented. Besides, if you are learning, your time 
is better invested if you learn generalities than learning how to use a 
particular library. The actual problem is the compiler. Yes, Mingw is free, 
but for sure it is not the best C++ compiler. Still a lot of work to do.
Sorry for bad English. Bye.

hi dev-cpp-users,

I am currently writing a little app, that shall act on changes to a
known file.

I am pretty new to windows programming so please be gentle..

I wrote a service so far, and at least on nt4 it
installs/uninstalls/runs just smooth.
down in main.c I have my old code without the service parts which ran
also.

the problem I found is that the app does not get notified abound
filechanges (service parameters '-fs c:\\temp' always given).
instead it does write lots of WAIT_FAILED notifications to the logfiel
(c:\temp\test.txt) a bunch at once without any hint what caused them
(even if no changes take place...)

I guess the mistake I made is somewhere in ca_action() but I can not
understand what it is..


 
regards
/Christian                   mailto:ca...@kr...

Hi all,
=20
Not technically a Dev-Cpp question, but I'm hoping somebody can help,
anyway. I'm working with an ODBC driver for Visual FoxPro 6 (as well as =
ODBC
drivers for several other RDBMSs). My application is supposed to loop
through a list of tables, run the single SQL statement "SELECT COUNT(*) =
FROM
tblname", get the result, then move on. At the end, I go back and tally =
all
the row counts.
=20
In the process, I am simply reusing all my handles (environment,
connections, and recordsets), calling SQLGetData and SQLCloseCursor =
after
each query.
=20
Now, here's the problem: even though I'm just doing SELECT COUNT(*), the
entire table is getting loaded into memory. My application's memory =
usage
goes from 6 MB to 100 +, though if I comment out just the FoxPro =
database
interaction, it stays around 8 MB, where I would expect it to be. The =
logic
and coding I'm doing for the FoxPro queries is absolutely identical to =
the
logic I'm using on the other databases, except, of course, for the
connection string, and I'm not having this problem with the other =
systems. I
should also point out that removing some of the larger tables from the =
list
of tables to check results in an almost perfectly corresponding drop in =
RAM
usage.
=20
For what it's worth, doing the same query directly from Visual FoxPro 6
results in a RAM spike under 1 KB.
=20
Anybody know what's wrong? Is there a driver setting I need to use or
something?
=20
Thanks!

I am feeling very confused about this issue. What I want to do is to 
write a member function that will return the size of an std::fstream.
I have this:
const std::streampos getFileSize() {
     // get file size
     std::streampos file_size;
     std::streampos currentpos = f.tellg();
     f.seekg (0, std::ios::end);
     file_size = f.tellg();
     f.seekg (currentpos);
     return file_size;
}
  'std::istream::tellg()' would work if I open the stream for input, but 
would it work if I open the stream for output?

I want to avoid having to write two member functions, one for 
'std::istream' and another for 'std::ostream'. Is this possible?

Hi,

I use this great tool for learning c++ and the editor seams to be better 
than commercial ide´s.

I found a bug in automatic indent (Ctrl+Shift+I). The function works by 
choosing it over the pull down menu, but the hot key doest work. I tried 
the Ctrl+Shift+U and a part of my text was deleted.

I use W2k Pro. German Version. In dev-cpp I use the german language, 
gnome icons and xp layout.

A bit of explanation of the error. The linker spitted this (what you 
posted):

g++.exe src/cobject.o src/cstring.o src/main.o src/cmemorystream.o 
src/capplication.o src/cwindow.o  -o "Core.exe" -L"C:/Dev-Cpp/lib" 
-lopengl32 -lfreeglut
src/capplication.o(.text+0xc):capplication.cpp: undefined reference to 
`_imp__glutInitDisplayMode@4'
src/capplication.o(.text+0x1e):capplication.cpp: undefined reference to 
`_imp__glutIdleFunc@4'
src/capplication.o(.text+0xb8):capplication.cpp: undefined reference to 
`_imp__glutDisplayFunc@4'
src/capplication.o(.text+0xca):capplication.cpp: undefined reference to 
`_imp__glutReshapeFunc@4'
src/capplication.o(.text+0xdc):capplication.cpp: undefined reference to 
`_imp__glutMouseFunc@4'

As you see, the linker cannot find symbols like "_imp__glutMouseFunc@4" 
etc. However, you might wonder why, as glutMouseFunc IS defined in the 
freeglut headers. But if you take a closer look, it is prefixed with 
"_imp_" which marks, that the linker is looking for an imported 
function, that is: a function, which is inside a DLL. And this happens 
because the compiler compiled your program without the define I wrote 
(-DFREEGLUT_STATIC), and by default, the headers of freeglut set up 
things to use the dynamic build of freeglut (FREEGLUT_DYNAMIC is the 
default).
So when you linked your program, the linker looked for imported 
functions, however the freeglut devpak contains a static build, and a 
static library's functions don't contain "_imp_" decorations. The linker 
saw the two as totally different symbols.

I hope that helps a bit to see the works in behind.
