txt内容:
aaaaaaaaaaaaaaaaaaa
bbbbbbbbbbbbbbbbbbb
cccccccccccccccccccccc
ddddddddddddddddddd
aaaaaaaaaaaaaaaaaaa
eeeeeeeeeeeeeeeeeee
ffffffffffffffffffffffffffffffffffffff
aaaaaaaaaaaaaaaaaaa
ggggggggggggggggggg
bbbbbbbbbbbbbbbbbbb
cccccccccccccccccccccc
现在我只要把相同的删除就留一行,比如aaaaaaaaaaaaaaaaaaa在里面有三行,只留一行就可以了,VB怎么能做到呢?
谢谢了
