vba中多列查询excel~返回行号,该如何处理

vba中多列查询excel~，返回行号
A             B             C
1     aa           bb           cc
2     aaa         bbb         ccc
3     aaaa       bbbb       cccc

条件是   列A   给定值aaa,列B   给定值bbb   列C给定值ccc,结果应该是第二行，但用VBA
该如何实现这个查询并返回行号？

------解决方案--------------------------------------------------------
Private Sub CommandButton1_Click()
Dim iIndex As Long '行号
Dim strRangeA As String 'A列
Dim strRangeB As String 'B列
Dim strRangeC As String 'c列

For iIndex = 1 To 65535
strRangeA = "A " + CStr(iIndex)
strRangeB = "B " + CStr(iIndex)
strRangeC = "C " + CStr(iIndex)
If (Sheet1.Range(strRangeA).Value = "aaa " And Sheet1.Range(strRangeB).Value = "bbb " And Sheet1.Range(strRangeC).Value = "ccc ") Then
MsgBox iIndex
Exit Sub
End If
If (Sheet1.Range(strRangeA).Value = " ") Then
Exit Sub
End If
Next
End Sub

刚下班比较匆忙
完善一点


Sub test()
Dim IsExist
IsExist=0

Set r = Selection

For n = 1 To r.Rows.Count
For j = 1 To r.Columns.Count
a = r.Cells(n, j).Value

If a=range( "D1 ").Value Then
msgbox range( "D1 ").Value & "在第 " & n & "行 "
IsExist=1

End If
Next j
Next n

if IsExist=0 then
msgbox "找不到查询数据 "
end if
End Sub


在选中部分查找range( "D1 ")的数据, 如有显示其所在行数.
