Indy 10 卸载及注意事项
1. Remove the package from Install Packages menu
从Delphi的IDE中卸载Indy组件包
2. Delete the *.BPL and *.DCP files of Indy from the installation directoy and from your System folder
从你的系统目录中删除以Indy开头的所有bpl和dcp文件
3. Remove any old old Indy files from your library path
从你的Delphi的Library path中删除所有Indy的路径
4。安装你的新Indy组件
安装很顺利(安装前请先卸载Delphi自带的Indy),不过加载项目进行编译的时候报错:
[Fatal Error] Unit1.pas(11): Unit IdContext was compiled with a different version of IdSocketHandle.TIdSocketHandle
解决方法也很简单:只要把下列路径(默认安装在C:\Program Files\Indy 10 for Delphi 7)加入Delphi的 Library Path即可。
C:\Program Files\Indy 10 for Delphi 7\Source\Core
C:\Program Files\Indy 10 for Delphi 7\Source\Protocols
C:\Program Files\Indy 10 for Delphi 7\Source\SuperCore
C:\Program Files\Indy 10 for Delphi 7\Source\System
