Get File's State Transitions Example (C#)

This example shows how to get a file's current and next possible state transitions.

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 StatesCSharp 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, 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 the vault contains a file in a workflow state.

// 5. Click Debug > Start Debugging or press F5.
//
// Postconditions: 
// 1. Displays the State Transitions dialog box.
// 2. Select a vault view.
// 3. Click Browse.
// 4. Displays the Select a file dialog box.
//    a. Select a file in the selected vault.
//    b. Click Open.
//    The selected file's path and file name appear 
//    in the Select a file dialog box.
// 5. Click Get state transitions
// 6. Displays a message box showing the name of the selected
//    file and its current and next possible state transitions.
// 7. Click OK to close the message box.
// 8.
Displays a message box showing whether the logged-in user must
//    add comment when transitioning the selected file to one of its next
//    possible states.
// 9. Click OK to close the message box.
//10. Displays a message box with the archive server log.
//11. Click OK to close the message box.

//12. Close the State Transitions dialog box.
