dev-cpp-users Mailing List for Dev-C++ (Page 20)

Hi and thank you for accepting my membership.
Am a new student of programming and would like to explore more about using
DevC++,
I will be greatful for your assistance.
Eddy.

Simple example...

SendMessage(hwnd, WM_CLOSE, NULL, NULL); // will send a WM_CLOSE to the window referenced by hwnd

Hope that helps,

Matt

I am not sure of how to send a MSG to the HWND.
Could someone provide a simple example?

I am just beginning to actually use windows as presentation for the programs I have been writing, and would really like to be able to make them pretty...
Thanks,

When you run your source code, if the compiling is OK, then the console
window appear for a fraction of second and instantly disappear. Now to
execute your .exe file, go to Start > Run > type cmd , then you get your
console window. Now go to DOS prompt, type cd c:\ and it will lead you to
DOS prompt. At DOS prompt type dev-cpp\MyPrograms or in whatever folder you
have saved your . c/.cpp file then type the file name. exe. Hit enter and
your program will be executed. It is always helpful  to make a folder named
MyPrograms  in MinGW under Dev-C++  and save your compiled source codes with
.c/cpp extension. The executed file will automatically be saved in
MyPrograms folder. Whenever you want to run the programs, you can do it from
MyPrograms folder. The console window will remain as long as you want and
can be exited by typing exit at DOS prompt. I hope this will be of some
help.

When a program returns it closes the console window. You need to add system("PAUSE"); before returning from main to hold it up.

If you still get this after declaring everything as double then you'll
have to write your own extended precision floating point class!

I feel that your problem has something to do with assigning the type of
integer to the variable. I hope you've assigned the type like signed,
unsigned, float , double etc. to the variable. Otherwise the compiler
accepts any type of integer how big or small provided the rules are
followed. Please try again.

I have resolved the problem, thanks!

Hi all:
I have a quiestion. 
when i have a variable taken a too small real value, the machine return an error, because for the machine this number is cero. How can i to avoid this problem and make operations with small real numbers?

Hi!

I am using a library (Pythia8108 -  a package for high energy physics 
simulations).
When I just include all library source files in my project, my project 
compiles.

However, when 1) I compile the library separately , creating .a file
2) add this .a file to my project mentioning its directory in "Library 
directories" in project options

I get a bunch of unresolved references.

When I copy the library file to the Dev C++ lib directory and mention it 
also in the Linker options of the project, the number of unresolved 
references decreases, but some still remain. I post the linker log below.

What could have possible go wrong?
Thanks,
Slava

That makes sense. I was thinking the same thing by using getpeername and storing the IP in a string list to be compared later.

But still don't understand when am I going to make the comparison of which address is gone. Is it inside the FD_CLOSE?
I believe that by the time FD_CLOSE message triggers the socket is already gone. So the question, in other words is, what function will I use to check which IP is gone. I believe inet_ntop only converts the IP to a readable IP. If I use getnameinfo or gethostbyaddr , it's going to take a little while to return to (NOT CONNECTED).

There are gui interface builders available also ( google for
glade,gazpacho -> GTK+ ,fluid -> fltk, not sure which one is used for
QT. ) GTK+ is the framework used for GNOME, QT is used for KDE.
Applications from either toolkit can be run on either desktop ( or any X
window manager as far as that goes ( fluxbox,openbox, windowmaker, etc )
as long as the OS is configured as a graphical desktop( i.e. has the
base underlying libs etc ).

GTK+ is primarily used by Gnome.  Qt is technically independent (Qt  
also works on Windows) but is the foundation from which KDE's SDK is  
built.  wxWidgets is a dedicated 100% cross-platform toolkit, so it  
works on Windows and Linux.

There are tools which automatically allow you to use any toolkit in  
any Windowing environment (so I could use GTK+ stuff in KDE) so really  
just pick one, you can't go wrong - except with GTK+ which you could  
go very wrong with, but I might just be a little opinionated there ;-)

  I fully understand your point. Thank you for the link. 
  However, the point I was trying to get across is that I may not need to code GUI applications for some given problem, however I would like to know how. 
  You have, indirectly answered my question, as I did not understand what was the diference betwen Qt, wxWidgets, GTK+, and their relations to KDE and GNOME... Each platform-toolkit, corresponds to a graphical interface in linux? GTK+ is only for GNOME? 

Thank you for the fast reply.

The Internet.

I'd suggest either wxWidgets or Qt.  GTK+, while heavily used, gives  
me an absolute headache (C-based GUI programming could be assembler  
for all I care - it's almost completely unreadable IMHO).

Read about Unix Theory.  The CLI is your friend!

http://en.wikipedia.org/wiki/ 
Unix_philosophy#Raymond:_The_Art_of_Unix_Programming

The basic theory I'm hinting towards is that you build a command-line  
tool which performs your application's purpose* and then build a GUI  
which provides a nice graphical interface to that later.

* if applicable - not always possible, for instance, say you want to  
build a PDF viewer or something like that - the command line would be  
completely inappropriate

Hi,

when I'm using allegro, this line is to compile it:
gcc -o main main.c `allegro-config --libs`

and when I'm using libglade, this line is used:
gcc -o main main.c `pkg-config --cflags --libs libglade-2.0`

But now I must use allegro and libglade together.

How I can compile this together?

Thanks

Sorry, but not a really good answer.

The included MinGW compiler is truly ancient.

If accepting the need that all third-party libraries (wxWidgets, ...) must
be retrieved as source and built, then it is way better to get the latest
MinGW compiler separately. MinGW has not stood still all these years...

An even better solution for all beginners who haven't invested time in
Dev-C++ projects is to get Code::Blocks (which is also using MinGW) that
does everything Dev-C++ does and a lot more. And is maintained.

Never ignore that little thing: Dev-C++ is not maintained!

Hello all. It's been awhile, but I have a question. When I try to 
compile my program in Dev using the full install with MinGW as the 
compiler, I keep getting the error message Linker error- undefined 
reference to _cpu_features_init. I was wondering if anyone could tell me 
where I screwed up.

google about BITMAPINFOHEADER and fopen
