Assigning Object Appearance and Behavior Using Properties
Properties are Object attributes that determine Object appearance or behavior. Color, count, name and ID all are
properties common to many objects. Some, such as ID, are usually read-only. Others can be changed. ER/Studio
immediately reflects property modifications by updating internal data.
Dim MyDiagram As Diagram
Dim MyModel As Model
Dim MyEntity As Entity
Dim EntName As String
Dim EntID As Integer
Set MyDiagram = DiagramManager.ActiveDiagram
Set MyModel = MyDiagram.ActiveModel
EntID = 1 ‘We want the name of the Entity that ER/Studio has identified as ID =1
Set MyEntity = MyModel.Entities.Item(EntID)
EntName = MyEntity.EntityName
‘Now we can display EntName in a MsgBox, write it to a text file, or
‘change it and re-name the Entity.
Performing Complex Actions Using Methods
Methods perform actions more complex than the simple setting or reading of a property. For example, OpenFile() is
a DiagramManager method that in turn invokes a number of other operations: it must navigate the directory/file
system, allocate resources for file handling, keep track of the file handle and attributes and so on.
Dim MyDiagram As Diagram
Dim strFile As String
strFile = "C:\Documents and Settings\Owner\Application
Data\Embarcadero\ERStudio\Model\MyModel.dm1"
Set MyDiagram = DiagramManager.OpenFile(strFile)
