<p>&nbsp;&nbsp;&nbsp; ●InStr(传回字串里某个字串在第几个字的位置)<br>
&nbsp;&nbsp;&nbsp; MyVal = InStr(Text1.Text, &quot;倩倩&quot;)<br>
&nbsp;&nbsp;&nbsp; MyVal = InStr(&quot;倩倩的VB网站&quot;, &quot;VB&quot;)<br>
&nbsp;&nbsp;&nbsp; MyVal = 4
<p>&nbsp;&nbsp;&nbsp; ●InStrB(传回字串里某个字串在第几个字符的位置)<br>
&nbsp;&nbsp;&nbsp; MyVal = InStrB(Text1.Text, &quot;倩倩姐&quot;)<br>
&nbsp;&nbsp;&nbsp; MyVal = InStrB(&quot;倩倩的VB网站&quot;, &quot;VB&quot;)<br>
&nbsp;&nbsp;&nbsp; MyVal = 7
<p>&nbsp;&nbsp;&nbsp; ●Len(传回字串有多少字数)<br>
&nbsp;&nbsp;&nbsp; MyVal = Len(MyStr)<br>
&nbsp;&nbsp;&nbsp; MyVal = Len(&quot;倩倩的VB网站&quot;)<br>
&nbsp;&nbsp;&nbsp; MyVal = 7
<p>&nbsp;&nbsp;&nbsp; ●LenB(传回字串有多少字符)<br>
&nbsp;&nbsp;&nbsp; MyVal = LenB(MyStr)<br>
&nbsp;&nbsp;&nbsp; MyVal = LenB(&quot;倩倩的VB网站&quot;)<br>
&nbsp;&nbsp;&nbsp; MyVal = 14
<p>&nbsp;&nbsp;&nbsp; ●StrComp(比较字串)<br>
&nbsp;&nbsp;&nbsp; MyVal = StrComp(MyStr1, MyStr2, 0)<br>
&nbsp;&nbsp;&nbsp; MyVal = StrComp(&quot;Abcd&quot;, &quot;abcd&quot;, 0)<br>
&nbsp;&nbsp;&nbsp; MyVal = -1<br>
&nbsp;&nbsp;&nbsp; MyVal = StrComp(&quot;Abcd&quot;, &quot;abcd&quot;, 1)<br>
&nbsp;&nbsp;&nbsp; MyVal = 0<br>
&nbsp;&nbsp;&nbsp; 传回值 = StrComp([字串1], [字串2], 比较模式)
<p>&nbsp;&nbsp;&nbsp; 传为值：<br>
&nbsp;&nbsp;&nbsp; 1 字串1 大于 字串2<br>
&nbsp;&nbsp;&nbsp; 0 字串1 等于 字串2<br>
&nbsp;&nbsp;&nbsp; -1 字串1 小于 字串2<br>
&nbsp;&nbsp;&nbsp; Null 字串1 与 字串2 都是 Null 字符
<p>&nbsp;&nbsp;&nbsp; 比较模式：<br>
&nbsp;&nbsp;&nbsp; 0 转成字码比较 (半型全型大小写不同)<br>
&nbsp;&nbsp;&nbsp; 1 字符比较 (半型全型大小写都相同)
