Roll Back Revisions Example (VB.NET)
This example shows how to roll back a checked-in file to
its first revision in the current version.
NOTE: If using the primary interop assembly
provided with SOLIDWORKS PDM Professional, see
Using .NET Framework 4.0 in
Stand-alone Applications.

' Preconditions:
' 1. Start Microsoft Visual Studio.
' a. Click File > New > Project > Visual Basic > Windows Forms Application.
' b. Type RevisionVBNET in Name.
' c. Click Browse and navigate to the folder where to create the project.
' d. Click OK.
' e. Click Show All Files in the Solution Explorer toolbar and expand
' Form1.vb in the Solution Explorer.
' f. Replace the code in Form1.vb with this code.
' g. To create the form, replace the code in Form1.Designer.vb with
' this code.
' 2. Add EPDM.Interop.epdm.dll as a reference (right-click the project
' name in the Solution Explorer, click Add > Reference, click
' Assemblies > Framework in the left-side panel, browse to the top folder of
' your SOLIDWORKS PDM Professional installation, locate and click
' EPDM.Interop.epdm.dll > Add > OK).
' 3. Right-click EPDM.Interop.epdm in References, click Properties, and set
' Embed Interop Types to False to handle methods that pass arrays of
' structures.
' 4. To find a file with a revision scheme:
' a. Open a vault view in File Explorer.
' b. Click a checked-in file.
' c. Click Display > History.
' d. Examine the Event column. If Revision is:
' * listed in the Event column, then the file
' has a revision scheme. Scroll down and examine the
' Event and Version columns to verify that at least three
' revisions exist for the current version of the file.
' * not listed in the Event column, then
' repeat steps 4b - 4d until you find a file with
' a revision scheme.
' 5. Click Debug > Start Debugging or press F5.
'
' Postconditions:
' 1. Displays the Get revision names dialog box.
' 2. Select a vault view.
' 3. Click Browse.

' a. Click the file identified in Preconditions step 4 in the
' selected vault.
' b. Click Open to display the selected file's path and file
' name in the Get revision names dialog box.
' 5. Click Get revisions.
' 6. Displays a message box listing the names of the revisions
' for the selected file. Click OK to close the message box.
' 7. Displays a message box showing the revision to which the file
' was rolled back and the current version. Click OK to close the
' message box.
' 8. Close the Get revision names dialog box.
' 9. Click the file in the vault in File Explorer for which revisions
' were rolled back.
