Batch Revoke State Transitions of Files Example (VB.NET)
This example shows how to revoke the state transitions of several
files in one batch.
NOTE: If using the .NET Framework 4.0 primary interop assembly
provided with SOLIDWORKS Enterprise PDM, see
Using .NET Framework 4.0 in
Stand-alone Applications.
'----------------------------------------------------------------------------
' Preconditions:
' 1. Start Microsoft Visual Studio 2010.
' a. Click File > New > Project > Visual Basic > Windows Forms Application.
' b. Type BatchChangeFileStates 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 Enterprise PDM installation, locate and click
' EPDM.Interop.epdm.dll, click Open, click Add, and click Close).
' 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. Ensure that:
' a. A workflow exists with
a No
Approval Required transition.
'
b. One or more vault files are transitioned to the Approved state using the
' No Approval Required transition.
' 5. Click Debug > Start Debugging or press F5.
'
' Postconditions:
' 1. The Revoke
state transitions dialog box displays.
' a. Select a vault view.
' b. Click Select files for
which to revoke transitions.
' c. In the Select File dialog:
' 1. Select a
file that transitioned to the Approved state using the
' No Approval
Required transition.
' 2. Click Open.
' 2. Click Revoke
transitions.
' 3. Click OK in the Revoke Transition dialog box.
' The selected file's
No Approval Required transition is revoked.
' 4. Close the Revoke
state transitions dialog box.
