freeing TStrings GetText buffer

freeing TStrings GetText buffer

freeing TStrings GetText buffer

The help on TStrings GetText says the caller needs to free the returned buffer. I have a memory checker that complains that I don't free the buffer.

char *tmpname;
tmpname = Msg->Lines->GetText();
... manipulate text...

What am I doing wrong??


RE: freeing TStrings GetText buffer

Allocates a text buffer and fills it with the value of the Text property.

virtual char * __fastcall GetText(void);


Call GetText to obtain a dynamically allocated character buffer containing all of the strings in the list. Individual strings are separated by a carriage return and line feed. The caller is responsible for freeing the returned value using the StrDispose procedure.

This example uses an edit control and a button on a form. When the button is clicked, memory is allocated for a copy of the text in the edit control, the text is displayed in a message box, and then the memory is deallocated.

void __fastcall TForm1::Button1Click(TObject *Sender)

  // Allocate memory.
  char* psz = StrNew(Edit1->Text.c_str());
  Application->MessageBox(psz, "StrNew, StrDispose Example", MB_OK);
  // Deallocate memory.
