uses ShellApi;
   
begin
  if ShellExecute(0, 'open', PChar('C:\xxx.exe'), nil, nil, SW_SHOW) < 32 then 
    ShowMessage('執行 C:\xxx.exe 發生錯誤: '   SysErrorMessage(GetLastError));
end;

引言: 我是用BCB 5.0 如果寫成如下 if ShellExecute(0, 'open', PChar('C:\xxx.exe'), nil, nil, SW_SHOW) <32 then ShowMessage('執行 C:\xxx.exe 發生錯誤: ' SysErrorMessage(GetLastError)); 在compiler時會有 Expression syntax的錯誤
