如何得到Windows的用户名称和产品序列号呢? 1. 可以用 WNetGetUser() 这个函数来得到 user name; 2. Windows 95 的产品序号可以用 TRegistry 到 Registry Database 中找出来; // 取得用户名称 function GetUserName: AnsiString; var lpName: PAnsiChar; lpUserName: PAnsiChar; lpnLength: DWORD; begin Result := ''; lpnLength := 0; WNetGetUser(nil, nil, lpnLength); // 取得字串长度 if lpnLength > 0 then begin GetMem(lpUserName, lpnLength); if WNetGetUser(lpName, lpUserName, lpnLength) = NO_ERROR then Result := lpUserName; FreeMem(lpUserName, lpnLength); end; end; { GetUserName } // 取得 Windows 产品序号 function GetWindowsProductID: string; var reg: TRegistry; begin Result := ''; reg := TRegistry.Create; with reg do begin RootKey := HKEY_LOCAL_MACHINE; OpenKey('Software\Microsoft\Windows\CurrentVersion', False); Result := ReadString('ProductID'); end; reg.Free; end;
