Application.IsObjectValid Property (Word)
True if the specified variable that references an object is valid. Read-only Boolean.
Syntax
expression .IsObjectValid(Object)
expression Optional. A variable that represents an Application object.
Remarks
The IsObjectValid property returns False if the object referenced by the variable has been deleted.
Example
This example adds a table to the active document and assigns it to the variable aTable. The example then deletes the first table from the document. If the table that aTable refers to was not the first table in the document (that is, if aTable is still a valid object), the example also removes any borders from that table.
Dim aTable As Table
Set aTable = ActiveDocument.Tables.Add(Range:=Selection.Range, _
NumRows:=2, NumColumns:=3)
ActiveDocument.Tables(1).Delete
If IsObjectValid(aTable) = True Then _
aTable.Borders.Enable = False
