Destroy Deleted Files in Vault Example (VB.NET)
This example shows how to create an application that displays a form in which
a user can select the vault in whose root
folder and subfolders all deleted files will be permanently destroyed. The user must have permission to delete
files.
NOTE: If using the primary interop assembly
provided with SOLIDWORKS PDM Professional, see
Using .NET Framework 4.0 in
Stand-alone Applications.
IMPORTANT: Do not recreate and run this
example if you do not want to destroy all deleted files in the root folder and
subfolders in the selected vault. Instead, SOLIDWORKS PDM Professional suggests
that you review the code to understand how you can programmatically destroy
deleted files in the root folder and subfolders of a vault.
