Windows Hook - Nachricht manipulieren / verwerfen?

[dominikkv]

ich kenn mich da auch nicht so aus, aber probiers vllt mal so:

Delphi-Quellcode:

function wndmsgHookProc(nCode: Integer; wParam: WPARAM; lParam: LPARAM): LRESULT; stdcall;
var
  handled: Boolean;
begin
  handled := False;
  case nCode < 0 of
    FALSE:
      begin
       if (PMsg(lparam).wparam = SC_Maximize) then
        begin
           handled := True;
           SendMessage(WindowHandle,WM_WND_MAX_MESSAGE,0,0);
        end;
      end;
  end;
  
  if handled then
    Result := 1 else
    Result := CallNextHookEx(HookHandle, nCode, wParam, lParam);
end;
