Q: Is it ok to cast a string to a pchar?

A: Yes. Delphi long strings (the default string type in 32-bit Delphi) are designed specifically to allow typecasting to PChar.

The following code is valid (with Delphi 2/3/4): 

procedure p;
var
  s : string;
begin
  s := 'Hello world';
  // set the current window's caption
  SetWindowText (GetActiveWindow, PChar(s));
end;
