If you care about case (will only match "sample", not "Sample" or "SAMPLE") :
    If tmpString.Contains("sample") Then
    End If

If you don't care about case (will match "sample", "Sample", and "SAMPLE"):
    If tmpString.IndexOf("sample", StringComparison.CurrentCultureIgnoreCase) > -1 Then
    End If
Very easy function

dim myBool as boolean
myBool = CheckField(tmpString, "sample")
    Public Function CheckField(ByVal strSentence As String, ByVal strWord As String) As Boolean
        If strSentence.IndexOf(strWord) > 0 Then
            Return True
            Return False
        End If
    End Function

Open in new window

If tmpString.IndexOf("Sample",1)>0 then
msgbox "String Exist..!"
msgbox "not present..!!"
end if
