Checking for records before trying to fill datagrid

[BukHix]

I want to check for matching records in my table before I try to fill the datagrid. Basicaly I don't want to open up a blank grid. How can I do this? Here is my String:

Try
    Dim Data_Adapter As SqlDataAdapter
        Data_Adapter = New SqlDataAdapter("Select " & _
        "Job," & _
        "Employee," & _
        "Phase," & _
        "PostDate," & _
        "Rate," & _
        "Hours," & _
        "Amt," & _
        "EarnCode," & _
        "InsCode," & _
        "PRDept, " & _
        "BatchSeq " & _
        "From aTable Where Employee='" & _
        (strEmp) & "' " & "Order by BatchSeq DESC", strCONN)
        
    Data_Adapter.TableMappings.Add("Table", "Stuff")
    m_DataSet = New DataSet
        Data_Adapter.Fill(m_DataSet)
    DataGrid3.DataSource = m_DataSet.Tables("Stuff")
