// The function copies the text of the specified window’s title bar

// (if it has one) into a buffer. The InternalGetWindowText function is

// much faster than the documented GetWindowText because it uses INT 2E interrupt

// NT-Specific!

// Here is the prototype for InternalGetWindowText:

(*

InternalGetWindowText(

hWnd: HWND; {a handle to a window or control with text}

lpString: PChar; {a pointer to a buffer to receive the string (UNICODE!!!)}

nMaxCount: Integer {the maximum number of characters to copy}

): Integer; {returns the length of the copied string}

*)

function NT_InternalGetWindowText(Wnd: HWND): string;

type

TInternalGetWindowText = function(Wnd: HWND; lpString: PWideChar;

nMaxCount: Integer): Integer;

stdcall;

var

hUserDll: THandle;

InternalGetWindowText: TInternalGetWindowText;

lpString: array[0..MAX_PATH] of WideChar; //Buffer for window caption

oemStr: PChar;

begin

Result := »;

hUserDll := GetModuleHandle(‘user32.dll’);

if (hUserDll > 0) then

begin @InternalGetWindowText := GetProcAddress(hUserDll, ‘InternalGetWindowText’);

if Assigned(InternalGetWindowText) then

begin

InternalGetWindowText(Wnd, lpString, SizeOf(lpString));

Result := string(lpString);

end;

end;

end;

procedure TForm1.Button1Click(Sender: TObject);

begin

ShowMessage(NT_InternalGetWindowText(Form1.Handle));

end;
