Delphi6和Delphi7的不同 ( 积分: 0 )

一段在Delphi6顺利编译的代码在Delphi7编译时候出现以下警告:
[Warning] Unit1.pas(116): Unsafe type 'PChar'
[Warning] Unit1.pas(126): Unsafe code 'GetMem'
[Warning] Unit1.pas(126): Unsafe type 'itm: PAnsiChar'
[Warning] Unit1.pas(130): Unsafe type 'itm: PAnsiChar'
[Warning] Unit1.pas(132): Unsafe type 'itm: PAnsiChar'
[Warning] Unit1.pas(135): Unsafe code 'FreeMem'
[Warning] Unit1.pas(135): Unsafe type 'itm: PAnsiChar'
[Warning] Unit1.pas(143): Unsafe code '@ operator'
[Warning] Unit1.pas(144): Unsafe code '@ operator'

我很菜,帮你顶一下!

这个没事！！！！！
好象在编译属性中改一个地方就不会出现[Warning]了、
据说和。Net有关！！！
查一查以前帖子吧！！！！

这就是说Delphi7不向下兼容了
