This example shows how to find the parent references of a file.

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 GetParentReferences_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. 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. Click Debug > Start Debugging or press F5.
//
// Postconditions: 
// 1. The Get parent references dialog displays.
// 2. Select a vault view.
// 3. Click Browse for file.
// 4. Locate and click one of the parts mentioned in Preconditions step 4.

// 5. Click Open.
// 6. Click Get parent references.

// 7. Displays the references of the selected part.
// 8. Click OK.

// 9. Close the Get parent references dialog.
