SOLIDWORKS PDM Professional API Help

Roll Back Revisions Example (C#)

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 C# > Windows Forms Application.
//    b. Type RevisionCSharp 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.dllAddOK).
// 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 checked-in file with a revision scheme and at least three 
//    revisions in the current version:
//    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 checked-in file 
//         with a revision scheme and at least three revisions for
//         the current version. 
// 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.
// 4. Displays the Select a file dialog box.
//    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.
//    a. Click Display > History.
//    b. Scroll down and examine the Event, Version, and Comment columns.
