GetWindowText -> string?

Is there any way to use a STL string as a parameter to GetWindowText?

Perhaps, something like:

Code:

---

int txtlen=GetWindowTextLength(hwnd);
std::string s;  //or use wstring for wchar_t
s.reserve(txtlen+1);
GetWindowText(hwnd,const_cast<char*>(s.c_str()), txtlen);

---

might do it but I suspect that it may be considered 'evil' to even consider attempting something like this. ;)

So, I suppose, the realistic answer has to be: no. :)

Well ken that looks pretty evil to me. But one could make function that uses a temporary char buffer to get the message and then copy that buffer into the std::string.

Code:

---

int GetWindowString(HWND hwnd, std::string &s) {
  char buffer[65536];

  int txtlen=GetWindowTextLength(hwnd);
  GetWindowText(hwnd, buffer, txtlen);

  s = buffer;
  return textlen;
}

---

But I'm sure that XSquared has already done this.

That's basically what I did. I was just wondering if there was a more 'elegant' way to do it.
