Title: Getting the windows directory.
Question: How can I determine where the Windows directory is?
Answer:
You can make a call to the Windows API function
GetWindowsDirectory.
If you want the system directory, simply call the Windows API function
GetSystemDirectory().
Example:
{$IFNDEF WIN32}
const MAX_PATH = 144;
{$ENDIF}
procedure TForm1.Button1Click(Sender: TObject);
var
a : Array[0..MAX_PATH] of char;
begin
GetWindowsDirectory(a, sizeof(a));
ShowMessage(StrPas(a));
GetSystemDirectory(a, sizeof(a));
ShowMessage(StrPas(a));
end;
