财务软件版1楼: 我这学期刚学这门语言,开始的时候还可以,但最近遇到了这个问题.让我解决不了了,我都无奈了,系统提示: [error] unitl.pas[399]missing operator or semicolon
[error]unit1.pas[399]incompatible types:＇＇string＇＇ and ＇＇Tmenultem＇＇
[fatal error]project1.dpr(5):could not compile used unit ＇＇unit1.pas＇＇
总是这样的语句出错,但这个语句有没错.我都郁闷死了!
then richedit1.Text:=copy(s,1,i-1)+new+copy(s,i+n,length(s)-(i+n)+1);

2楼: 数据类型不一致 ,n,i,new,s他们是什么类型的？用友财务软件记账

3楼: 是这个类型了!
var i,n:integer;
s,old,new:string;就是检查不出来呀!

4楼: 晕，你一个菜单项的名字也叫 Copy，它和你准备调用的系统函数 Copy 名字冲突啦。
两个办法：
1、把那个叫 Copy 的菜单项改为 miCopy；
2、在你出错的地方，把所有的 Copy 均改为 System.Copy 指明调用系统单元里面的函数。

5楼: 谢谢你帮我解决了问题.如果可以的话.我可以用QQ加你吗？以后如果我有问题的时候就可以向你请教了!再次感谢了!QQ:329008799

6楼: 看到你解决了问题我很高兴，不过很抱歉，QQ 为老婆专用 [:D] 有问题就上来提就是了，这里还是有很多热心人的，顶多发贴后要是看见没人顶，把帖子链接发到 xbeta＠tom.com，我来帮你顶就是了 [:)]
