vb 字符串每隔一定长度，插入 换行符 ，有汉字长度的处理?
一组字符串，字符串长度不确定，要求每隔8个字符串，插入一个换行符,如
"1234567890"转换后为
"12345678
90".
另外还要求汉字长度处理，一个汉字按两个字符处理，即
"一二三四五六七八九十"转换后为
"一二三四
五六七八
九十".
特别难的是:字符串中有数字，英文和汉字同时出现，而且数字和英文是单数，如"123456a字bcd".
我处理不了，难死了！谁能帮一下? --------------------编程问答-------------------- 前两种情况:
Private Sub Form_Load()--------------------编程问答-------------------- 写漏了，我不是问换行符是什么，我知道换行符是 chr(10) --------------------编程问答-------------------- 太厉害了。
Dim s, ss, s1, s2, s3
s1 = "1234567890995316770"
l1 = Int(Len(s1) / 8)
If l1 < 1 Then
MsgBox "长度小于8"
Else
For i = 0 To l1 - 1
s = s & Mid(s1, i * 8 + 1, 8) & vbCrLf
Next
End If
s = s & Right(s1, Len(s1) - l1 * 8)
MsgBox s
s2 = "一二三四五六七八九十"
l2 = Int(Len(s2) / 4)
If l2 < 1 Then
MsgBox "长度小于4"
Else
For i = 0 To l2 - 1
ss = ss & Mid(s2, i * 4 + 1, 4) & vbCrLf
Next
End If
ss = ss & Right(s2, Len(s2) - l2 * 4)
MsgBox ss
End Sub

End Sub --------------------编程问答-------------------- 字符串中有数字，英文和汉字同时出现 那你就判断啊 数字，英文一个字符 汉字两个字符
从0开始逐一的加 如大于8(7直接跳到9,那就看你该如何处理了)
重点在于你要如何判断每个字符是否为汉字, 这才是你问题之所在
用下面这代码自己改一下吧
'********************************************
'汉字 16进制区间 B0A1-F7FE
'汉字10进制区间 45217--63486
'汉字区位: 16区位01-94 ---- 87区位01-94
Option Explicit
Dim i&, Rtn&, aa$
Private Sub Command1_Click()
MsgBox IIf(ChkHZ(Text1.Text), "字符串中有汉字", "字符串中没有汉字")
End Sub
Public Function ChkHZ(ChkStr As String) As Boolean
ChkHZ = False
For i = 1 To Len(ChkStr)
Rtn = Str2Dec(Mid(ChkStr, i, 1))
If Rtn >= 45217 And Rtn <= 63486 Then ChkHZ = True: Exit For
Next i
End Function
Public Function Str2Dec(TxtStr$) As Long
aa = Hex(Asc(TxtStr))
aa = IIf(Len(aa) = 2, "00" & aa, aa)
Str2Dec = Val("&h" & Left(aa, 2)) * 256 + Val("&h" & Right(aa, 2))
End Function
--------------------编程问答-------------------- 其实难度并不大。
既然是‘中英混合’，象："123456a字bcd" 这种，是弄成：
123456a字
bcd
还是：
123456a字
bcd
呢？这个规则得由你自己定啊！
还有，是只插入换行符（一个字符），还是插入回车换行符（两个字符）呢？
你得说确切点啊。
--------------------编程问答-------------------- 提供一个思路，代码自己完善
--------------------编程问答-------------------- 顶下！ --------------------编程问答-------------------- 判断不难，将字符串中的每个字符单独分析，使用ascii码直接转换后，所有非95可打印字符的内容都是负值。 --------------------编程问答--------------------
