大师这回复太高深
来个通俗的实例啊
谢谢


一、 读入幻灯片的二进制数据

(setq slddata (xd::file:readbinary "d:\\1.sld" nil nil))

命令: !slddata

67 0 46 0 7 255 33 0 60 0 37 0 63 0 0 252)


二、把上面的表中的每项转成16进制字符串,不够两位的,比如里面的0,前面补0,变成"00",这样确保以后解密的时候,没2个字符串对应一个16进制

  1. (setq hexdata (mapcar '(lambda (x)                                    (setq hex (xd::math:int->hex x))
  2.                                     (if (= (strlen hex) 1)
  3.                                       (strcat "0" hex)
  4.                                       hex
  5.                                     )
  6.                                   )
  7.                                  slddata
  8.                          )
  9. )


得到:

命令: !hexdata

三、然后把他们连成一个字符串

(setq hexstrs (apply 'strcat hexdata))

命令: !hexstrs

四,进行BASE64编码

(setq base64 (xdrx_string_encode hexstrs))

得到:

命令: !base64
"NDE3NTc0NmY0MzQxNDQyMDUzNmM2OTY0NjUwZDBhMWEwMDU2MDI4YjAwNmIwMGJlMzhjNjAwMDIwMDM

有点眼熟吧,和OPDNDCL的对话框数据一样的,这个字符串你就可以打包到你的VLX里面了。

用幻灯片的时候,你把上面的操作逆一下,得到幻灯片的二进制数据,存成SLD就可以了。
