Batch Revoke State Transitions of Files Example (C#)

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 PDM Professional, see Using .NET Framework 4.0 in Stand-alone Applications.

//----------------------------------------------------------------------------
// Preconditions:
//  1. Start Microsoft Visual Studio 2010.
//     a. Click File > New > Project > Visual C# > Windows Forms Application.
//     b. Type BatchChangeFileStates_CSharp 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.cs in the Solution Explorer.
//     f. Replace the code in Form1.cs with this code.
//     g. To create the form, replace the code in Form1.Designer.cs 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, click Open, and click Add).
//  3. Add Microsoft.VisualBasic as a reference (click COM in the left-side 
//     panel, click Microsoft.VisualBasic, click Add, and click Close).

//  4. 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.

//  7. 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.
