Change Card Variables Add-in Example (C#)

This example shows how to create an add-in that pops up a message box when a file is approved.

//--------------------------------------------------------------------------------------
// Preconditions:
// 1. Start Microsoft Visual Studio 2010.
// 2. Click File > New > Project > Visual C# > Class Library.
// 3. Select .NET Framework 2.0 in the dropdown at the top of the dialog.
// 4. Type CardVariables_CSharp in Name.
// 5. Click Browse and navigate to the folder where to create the project.
// 6. Click OK. 
// 7. Right-click the project name in the Solution Explorer and click Add Reference. 
// 8. In the Add Reference dialog:   
//    a. Add the SOLIDWORKS PDM Professional type library as a reference (click COM in the
//       left-side panel, click PDMWorks Enterprise nnnn Type Library, 
//       and click Add).
//    b. Click Assemblies > Framework in the left-side panel, click Microsoft.VisualBasic,
//       and click Add.
//    c. Click Close.
// 9. Right-click the project name in the Solution Explorer and click Properties.
//10. In the Properties window:
//    a. On the Application tab, click Assembly Information.
//    b. De-select Make assembly COM-Visible.
//    c. On the Build tab, select Register for COM interop.
//11. Save the project.
//12. Copy the code below to Class1.cs.
//13. To populate the GUID attribute, click Tools > Create GUID in the IDE,
//    select GUID Format 5, click Copy, and click Exit. Populate [Guid(""),...] with
//    the copied string.
//14. Click Build > Build Solution.
//
// Postconditions: 
// 1. Open the SOLIDWORKS PDM Professional Administration tool, expand a vault_name node, 
//    and log in as Admin.
// 2. Under vault_name, right-click Add-ins, and click New Add-in.
//    a. Navigate to the bin\Debug directory of your built project.
//    b. Click Interop.EdmLib.dll and CardVariables.dll.
//    c. Click Open.
//    d. Click OK.
// 3. Click OK after reading the SOLIDWORKS PDM Professional warning dialog.
// 4. In the taskbar, click the Administration tool blueberry and click Log off > vault_name.
// 5. Open Windows Explorer on a view of vault_name to:
//    a. Log in as Admin.
//    b. Create, check in, and check out a file whose data card contains Project Name 
//       and Project Number.
//    c. Click the Data Card tab.
//    d. In Project Name, type Mercury, Venus, Earth, Mars, Jupiter, or Saturn.
//    e. Observe the change in Project Number.
//    f. In Project Number, type a number between 1000 and 1005.
//    g. Observe the change in Project Name.
