Question about (lstrcmpi)

I have this:

Code:

---


hExtra=CreateFile("Path.txt", GENERIC_READ, FILE_SHARE_READ, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL);
ReadFile(hExtra, Buffer, 100, &dwBytes2, NULL);
 
DeleteFile(Buffer);

---

But it did not work, then I tried this:

Code:

---


TCHAR Buffer[100];
 
hExtra=CreateFile("Path.txt", GENERIC_READ, FILE_SHARE_READ, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL);
ReadFile(hExtra, Buffer, 100, &dwBytes2, NULL);
 
DeleteFile(Buffer);

---

But that didn't help either.
Ken Fitlike helped me on a question very simalar to this before and it used the lstrcmpi function. So I assume this problem would use it too. But I don't know how I should use it. Any help? Thanks in advance.

This doesn't help either:

Code:

---

lstrcmpi(Buffer,_T(Buffer));

---

Drop the _T macro - like any other macro it does a literal text substitution; you should only use it on pure text, never a variable name.

If you want to delete a file who's name is stored in Path.txt then you don't need lstrcmpi to do that since lstrcmpi is used to compare to strings.
I have a feeling your problem is caused by the string being read in from the file not being NULL terminated since .txt files don't usually contain zero bytes.
You could loop thru the buffer and change all '\r' and '\n' charactors to zeros that would mean you end a line with a zero.

Code:

---

int Index=0;

hExtra=CreateFile("Path.txt", GENERIC_READ, FILE_SHARE_READ, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL);
ReadFile(hExtra, Buffer, 100, &dwBytes2, NULL);
while(Index<99)
  {
      if (Buffer[Index]=='\r' || Buffer[Index]=='\n')
        break;
      Index++;
  }
  Buffer[Index]=0;
DeleteFile(Buffer);

---

In this example the program loops untill it finds a '\r' or '\n' charactor or it reaches the end of the buffer and adds a zero.
If the file is going to cotain more then one line then you should create a function to either get a single line from the file at a time or split the input up into lines.
