用这个函数,构造吧 Returns the index value of a substring.UnitStrUtilsCategorystring handling routinesDelphi syntax:function PosEx(const SubStr, S: string; Offset: Cardinal = 1): Integer;C++ syntax:extern PACKAGE int __fastcall PosEx(const AnsiString SubStr, const AnsiString S, unsigned Offset = 1);DescriptionPosEx returns the index of SubStr in S, beginning the search at Offset. If Offset is 1 (default), PosEx is equivalent to Pos.PosEx returns 0 if SubStr is not found, if Offset is greater than the length of S, or if Offset is less than 1.
SubStr是子串,要是那个长字符串,Offset是从第几个位置开始找
o 哦 ，我 的是D5的，找不着.看来只能自己编写函数了。thank you all the s。ame.
