请问压缩数据()和解压数据(),炫语言有官方命令吗?
本帖最后由 呵呵仙 于 2024-9-17 19:41 编辑请问压缩数据()和解压数据(),炫语言有官方命令吗?这个命令在易语言经常用的,炫语言没有不应该吧!
问了下百度AI.嵌入代码后报错了!!不知如何搞!?

模块安装失败.现在只好先用以下这个方法了!

你这里没报吗? 呵呵仙 发表于 2024-9-20 21:32

重新下载看看，构造函数没定义，但我这里确实没报错 hxznhf 发表于 2024-9-20 21:42

要带DLL发布吗?

dll忘记传了，本来打算编译静态版本，但是现在发现静态问题比较多，不同VC版本静态库之间没法完全兼容，看来除了带dll，只有源代码编译兼容性最好了。
