going crazy over copy

Im going crazy over this piece of code, it compiles but the exe is huge
and it doesent copy corectly, the file in program files is 0 kb.. (so empty)
could annybody please tell me what to change or maybe use another
command.. (what i basicly want to do is copy the file that is being
executed to another directory)
thanx !

Code:

---

const char *src = "\\instal.exe";
ifstream input(src,ios::binary);

const char *dst = "c:\\Program Files\\myprogram.exe";
ofstream output(dst,ios::binary);

output <<input.rdbuf();

>the file in program files is 0 kb.. (so empty)
How do you know it's empty? Did your C++ program exit before you checked the file's size?

Two seperate problems:
1) The exe is huge because its being compiled with debugging symbols.
2) Is the file name correct?

const char *src = "\\instal.exe";

Most install programs are spelt with 2 l's.

Code:

---

const char *src = "\\install.exe";

---

yes the names are correct and yes the program was done
when i checked the file size, i tested it like 20 times..
thanx though

Add some error checking to see if the files opened correctly.

Code:

---

const char *src = "\\instal.exe";
ifstream input(src,ios::binary);
if (!input.is_open())
{
  cout << "Unable to open input file." << endl;
  return 1;
}

const char *dst = "c:\\Program Files\\myprogram.exe";
ofstream output(dst,ios::binary);
if (!output.is_open())
{
  cout << "Unable to open output file." << endl;
  return 2;
}

output <<input.rdbuf();

---

See if it displays either message.

doesent give anny errors but stil doesent copy right..
thanx though..

(dont know if i specified clearly that the file in wich this piece
of code is, is the instal.exe so the source file that i trie to copy.
dont know if this matters or not though)

>is the instal.exe so the source file that i trie to copy.
Well since the input file opened ok, I don't think it matters. Try closing the files.

Code:

---

output <<input.rdbuf();
input.close();
output.close();

---

Try this:
1) move the program into a temp directory.
2) Make a fake instal.exe that has some message.
3) instead of outputting to another file output it to the screen so you can see what you get

wel gues i found one problem..

instead of

Code:

---

const char *src = "\\instal.exe";

---

i put in

Code:

---

const char *src = "instal.exe";

---

now the file copy's and runs wel, but i made a "test"
wich has like 10 lines of code, just included what i needed
to make it run, its stil 440 ko...
wich i think is a lil bit to much for 10 lines of code..
now i never debuged something, i use dev c++
tried (after compiling) to hit the debug button but it says
Project is not compiled... maybe some last advice on
how i debug this

thanx ..

To remove the debugging symbols and reduce the file size
In Dev-C++:
Tools -> Compiler Options -> Settings -> Linker -> Generate debugging information -> No

the Generate debugging information is already set on no...
thanx though
