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.

//10. Replace the code in Form1.cs with this code.
//11. To create the form,
replace the code in Form1.Designer.cs with this code.
//12. 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.
