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
(65 117 116 111 67 65 68 32 83 108 105 100 101 13 10 26 0 86 2 139 0 107 0 190

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. )
   

(setq hexdata (mapcar '(lambda (x)                                    (setq hex (xd::math:int->hex x))<br />                                     (if (= (strlen hex) 1)<br />                                       (strcat "0" hex)<br />                                       hex<br />                                     )<br />                                   )<br />                                  slddata<br />                          )<br /> )<br />

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

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。

你把上面的字符串和第三步里面的对比下，看看是不是一样的？

完整的打包函数

1. (defun binfile2base64 (sld)
   
2.   (if (setq sld (findfile sld))

6.                                     (if (= (strlen hex) 1)
   
7.                                       (strcat "0" hex)

一、 读入幻灯片的二进制数据

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

实在感谢
看上去太复杂了
不敢试

lt1058479745

命令: (xd::obj:dxf (entget (entlast)) 10)
