I am now developing word template customization by vba in Ms office 2013 with WorkSite 9.0.28.

When I press "Save As" Button, it always show Work Site Save As Dialogue automatically,

but I must need to stop / suppress to showing this Work Site Save As Dialogue, because I want to call my customized vba logic instead of this dialogue.
P.S.
1) This "Save As" Button must be keep because it need to be used in some of my other customized word templates.
2) I have already try the event handler in vba such as:
Private Sub XXXXX_DocumentBeforeSaveAsOptions(ByVal Doc As Variant, IgnoreIManageSave As Boolean)
but still can't solve the problem
May you please kindly give me advices if you have any ideas? Thanks very much!
