Is there a smarter way to code the following ? Ts

Private Function IsPrice(stCode As String) As Boolean

On Error Resume Next

If InStr(stCode, "9K") > 0 Then
    IsPrice = True
    Exit Function
ElseIf InStr(stCode, "14K") > 0 Then
    IsPrice = True
    Exit Function
ElseIf InStr(stCode, "16K") > 0 Then
    IsPrice = True
    Exit Function
ElseIf InStr(stCode, "18K") > 0 Then
    IsPrice = True
    Exit Function
ElseIf InStr(stCode, "10K") > 0 Then
    IsPrice = True
    Exit Function
End If

HI,

You could try

Private Function IsPrice(stCode As String) As Boolean

If stCode Like "*9K*" Or stCode Like "*14K*" Or _
        stCode Like "*16K*" Or stCode Like "*18K*" Or stCode Like "*10K*" Then
    IsPrice = True
Else
    IsPrice = False
End If
End Function

Private Function IsPrice(stCode As String) As Boolean

IsPrice = (stCode Like "*9K*" Or stCode Like "*14K*" Or _
        stCode Like "*16K*" Or stCode Like "*18K*" Or stCode Like "*10K*")
End Function

Try this

Private Function IsPrice(stCode As String) As Boolean
Dim sPrice As String

sPrice = "9K,14K,16K,18K,10K"
If InStr(1, stCode, sPrice) <> 0 Then
    IsPrice = True
Else
    IsPrice = False
End If

End Function

bear in mind that depending on what one of the above 3 you choose, you can get TRUE returned for:-

9K
9K,14
16Kilo
118Kettles

Is this what you wanted?

@gowflow

your code will only work if you swap sPrice and stCode and only if the string test consists only of 9K or 14K, etc.
Private Function IsPrice(stCode As String) As Boolean
Dim sPrice As String

sPrice = "9K,14K,16K,18K,10K"
If InStr(1, sPrice, stCode) <> 0 Then
    IsPrice = True
Else
    IsPrice = False
End If

End Function

Sorry I missed something it should be this

Private Function IsPrice(stCode As String) As Boolean
Dim sPrice As String
Dim vPrice
Dim I As Long

sPrice = "9K,14K,16K,18K,10K"
vPrice = Split(sPrice, ",")

For I = LBound(vPrice) To UBound(vPrice)
    If InStr(1, stCode, vPrice(I)) <> 0 Then
        IsPrice = True
        Exit For
    End If
Next I

End Function

As the questioner does not explain EXACTLY what the contents of stCode could be at the point of calling the function then all anybody can do is make a guess at what is wanted.

IF the only contents would be an exact strink of "9K"  or "14K" or "16K" or "10K" etc then none of the above are optimal.  What happens when your stock codes change or you add a new one?

If indeed you only have and only ever will have those 5 stock codes then something like the above would work.

However if your stock is fluid and liable to change the I would suggest that you read the available stock codes into an array from the database and validate against those each time.
