Excel VBA：如何查找某个子字符串

Question

In column B, I have data for eg hmc1, hmc2, hmc3. I want to find every Column B cell that contains "hmc" and replace its corresponding cell in Column A with "Found". My code so far works if it matches fully, but not if it matches a substring.

        If .Range("B" & r).Value = "hmc " Then
            .Range("A" & r).Value = "Found"

Col A   Col B
Accept  hmc1
123     hmc1
123     hmc2
Accept  xcc
Accept  xcc
Accept  xcc
Accept  xcc
Accept  xcc
Accept  xcc
Accept  xcc
Accept  xcc
Accept  xcc
Accept  xcc
123     hmc3
Accept  hmc3
Accept  hmc3

Answer 1

Assuming your B column data starts with 2

Sub test()
    Dim lastrow As Long
    lastrow = Range("B" & Rows.Count).End(xlUp).Row
    For i = 2 To lastrow
        If InStr(LCase(Range("B" & i).Value), "hmc") Then
            Range("A" & i).Value = "Found"
        End If
    Next i
End Sub
