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

Hi,

In my upcomming application i am writing for windows i want to add a =
button in its GUI which makes it enable to popup a
filebrowser or directorybrowser. i am looking for examples on this =
matter. i gues the standard explorer of windows can
be used i gues but i don't know what is required..=20

Danny.

Hi,

"By the press of a button" what kind of buttons do you exactly mean?

Hi,

CAn anyone tell me how do I run a c program say by the press of a button. Or 
  also maybe a procedure.

THANKS

Thanks. I think I just reinvented the wheel.
But mine is a bit square :)

Hello everyone!

As far as I know, there is no linked list implementation in the C standard 
library. If someone knows of a good implementation of a linked list (sorted or 
unsorted), please let me know. (C only)

Although I have made an implementation of it, I don't know what kind of 
interface would be good. I have made the following:

This is the header for my "list.h":

   typedef int (*compproc)(void*,void*);

   typedef struct _node{
     void* value;
     struct _node *prev;
     struct _node *next;
   }*pnode;

   typedef struct _list{
     int length;
     pnode first;
     pnode last;
     compproc cmp; /* if NULL, the list is unsorted */
   }*plist;

   /* list management */
   plist list_create(compproc cmp);
   void list_destroy(plist pl);
   pnode list_add(plist pl, void* value);
   int list_remove(plist pl, pnode pn);
   int list_length(plist pl);

   /* list utility functions */
   pnode list_search(plist pl, void* value);

If one wants to iterate through the list, a simple for will make it:

for(pnode=plist->first;pnode!=NULL;pnode=pnode->next){
   ...
}

The list is a doubly linked non-circular list (for fast operations).

The list is sorted with the cmp function, specified at the creation of the list. 
(the same as the cmp in the qsort() in C) At each list_add() the element will be 
automatically inserted sortedly. If NULL is given, the list will be unsorted.

My question is, is this interface is a good one, or should I make changes. The 
reason why I want to know this, is because I am making a library, which will 
contain this list, and I want to know whether it is useable well?
I will release this list implementation separately (for even you), if you think 
it is good enough.

ALL suggestions are welcome. Thank you.

You must not set WS_HSCROLL. And set WS_VSCROLL if you will need more space.

g++ is the c++ compiler, the three before it are related but I don't
know well about them.
c++filt is for options like strip symbols and such.
See command prompt> program --help.
gcc is the compiler for C, if you call it over a C++ code it will call g++.
mingw32- are the same that the ones without mingw32-, made so you can
have mingw and cygwin, and so you can differentiate both.

These seems that make something about controlling command options and
passing communication between compiler and linker... depending on the
kind of source you use.

Hi,

I think I just solved it. I read some about makefiles and saw that by
including a makefile that contained

override OBJ=3Dobjects/*

it should work and it did, phew...Hopefully I can start working now,
thanks for the hints Abhijit and Per (du kanske =E4r svensk Per, is s=E5
fall s=E5 kanske tack =E4r p=E5 sin plats).

Two possibilities:
create.open("C:\\Service Hub\\Names.dat", ios::out);  :
\\ wil be interpreted as a single \
or (prefered)

create.open("C:/Service Hub/Names.dat", ios::out);  :
Use forward slash.
Although windows is using the backslash as directory separator, in all C and
C++ functions you can also use
the forward slash. In this way you can also write compatible code with
normal operating systems.

Subject: [Dev-C++] UNKNOWN ESCAPE SEQUENCE




Hi all, 

I am trying to write to a file in my disk by putting in the complete
pathname in the filename parameter, as my books suggest , 

----------------------------------------------------------------------------
-------------------- 
#include<fstream.h> 


ofstream create;  //declaring a file stream for writing 
main() 
{ 
create.open("C:\Service Hub\Names.dat", ios::out);  
/************************************************ 
/******************************************* 
Here I get errors unknown escape 
sequences \S and \N. 
How can I tell C++ that that is a part and not an escape sequence? 
*************************************/ 
  

create<<"Mpho Dondolo\n"; 
create<<"Lindeka Dondolo\n"; 
create<<"Limpho Dondolo\n"; 
create.close(); 
return 0; 
} 

Hi,

as you may have notices I have had trouble with the linking step,
probably due to too many objects that results in a too long command line
in windows. I actually checked this by modifying the makefile manually
and compiled the project in a MS-DOS window and it worked. I did the
same thing without modifying the makefile generated by DEV-C++ and I got
the same errors so I have pretty much located the problem. What I want
to do is to force DEV-C++ to build the makefile with the line

OBJ = objects/*

instead of (as it does by default)

OBJ = objects/obj1.o objects/obj2.o objects/obj3.o ...etc

Is there a way to do this within the GUI of DEV-C++ or am I stuck with
linking in the MS-DOS prompt? I would assume that there are others who
have had similar problems. If you have other suggestions on how to solve
the problem (without modifying the .cpp or .h files), please let me
know, it would make a world of difference to me...
