本人涉及到字符串包含的问题，即判断一个字符串是否包含另一个字符串或字母，请高手指教具体的代码！！
以下是我的错误代码，在此仅供抛砖引玉，望高手不吝赐教！！

Dim StrA
Dim StrB
Dim StrC

StrA = "Jason"
StrB = "Serena"
StrC = "o"

If StrA >= StrC Then
        Reporter.ReportEvent 0, StrA, "contains" & " " & StrC
Else
        Reporter.ReportEvent 1, StrA, "doesn't contain" & " " & StrC
End If

If StrB >= StrC Then
        Reporter.ReportEvent 0, StrB, "contains" & " " & StrC
Else
        Reporter.ReportEvent 1, StrB, "doesn't contain" & " " & StrC
End If

用函数instr()

Thank You~~
