Select component by name in assembly

I want to select component by name  for example Sub-assembly / part name contains  " xxx" .

I managed to filter the components by its name (refer the code below). but I not able to select those components.

Anyone kindly help with this.

Thanks a lot.

Dim swApp As SldWorks.SldWorks

Dim swModel As SldWorks.ModelDoc2

Dim swAssy As SldWorks.AssemblyDoc

Dim vComps As Variant

Dim swComp As SldWorks.Component2

Dim i As Integer

Dim j As Integer

Dim FileName As String

Dim SearchString As String

' Enter the string here to find

Const FindChar As String = "PD"

Sub main()

    Set swApp = Application.SldWorks

    Set swModel = swApp.ActiveDoc

    Set swAssy = swModel

    swModel.ClearSelection2 True

    vComps = swAssy.GetComponents(False)

    For i = 0 To UBound(vComps)

    Set swComp = vComps(i)

    FileName = swComp.Name2

    SearchString = FileName

        For j = 1 To Len(SearchString)

            If Mid(SearchString, j, 2) = FindChar Then

              swComp.Select2 True, -1

                Debug.Print FileName

            End If

        Next j

    Next i

End Sub
