Description
This is the main object through which all other objects are accessed from. The Programmatic ID (PROGID) for this object is 'ERStudio.Application'. Macros, which run inside ER/Studio's Macro Editor, will use the pre-initialized 'DiagramManager' object.
Object Model
...
Remarks
Within the Macro Editor, DiagramManager is the parent object that provides access to all other ER/Studio objects. The DiagramManager object is declared/created when you start the Macro Editor. You can immediately start using this object. You do not need to create it.
Good Programming Practice: Use the Use the DiagramManager.GetLastErrorCode() or DiagramManager.GetLastErrorString() to check for errors after method calls.
If you run macros outside of the ER/Studio Macro Editor (for example, in in Visual Studio), you must create the Application object through a method call. In Visual Basic, you can call CreateObject. The Programmatic ID (PROGID) for the Application object is ERStudio.Application.
In this external case, you'll need to create a link to the ER/Studio Type Library and declare ERStudio object types. Example applications in VB6, and .Net VB and C# are in your installation directory under "..\ERStudioX.X\Readme\TableList.zip."
