File Garbage

I have a function that writes a "block" of code to a file.

The problem is, it writes like it is supposed too, but at the end there are characters I didnt tell it to write(jarbled up garbage).

What causes this to happen and how can I stop it?

Usually by opening the file in binary mode

post the code

Code:

---

void Obj::WriteRef(char *RefBuffer, long size, char *RouteName)
{
  char FilePath[255];
  sprintf(FilePath, "C:\\Program Files\\Microsoft Games\\Train Simulator\\Routes\\%s\\%s.ref", RouteName, RouteName);

  ofstream REF(FilePath, ios::app);

  if(!REF.is_open()) {
    cout << endl << "Error Writing Ref";
    cin.get();
    exit(1);
  }

  REF << endl << endl;
  REF.write(RefBuffer, size);

  REF.close();
}

Does C++ automatically open in binary? If so, can I treat it as a text file?

Just to show you whats happening

Code:

---


static (
  class ("Blah")
  shape(Foo)
  Align(none)
)

static (
  class(Bar)
)  pA ÔD@ ”tA ê@

---

Thats what it puts out... wich is fine except for
pA ÔD@ ”tA ê@

I cant for the life of me figure out where that last bit is coming from... so odd!

I dont mean to keep bumping this thread or seem impatient, but its driving me bonkers. This is the only little bug I need to work out before the program is finished. I have searched google HIWORDs and LOWORDs and cant find any thing.

Your size is too large and you are writing random characters.

If RefBuffer is a null terminated character string just use:

Code:

---

REF << RefBuffer;

---

or

Code:

---

REF.write(RefBuffer, strlen(RefBuffer));

---

Otherwise, fix your code so that size is correct. If you still have problems, post the code where size is calculated.

Erm, why are you treating what appears to be a text file as a binary file?
You also need to show how you set up your RefBuffer, and how you calculated the length.

I used strlen and it worked. Thank you.

I got the size by opening the file, using seekg to pint at the end, then assigning the value of tellg to a const long called size. The function then returned "size" and I made
char RefBuffer[size];

Thanks Again

I am? I didnt realize it. How can I treat it as text then.
