You can add a dynamic object to a form by changing the Direction property of its associated attribute. When the direction is changed, a default Text box is placed on the form.
To add an attribute to a form by changing its Direction property, perform the following:
Click Class View on the View menu to open the Class View window.
Open an existing form, or create a new one.
Select the attribute you want to add to the form as an object.
Note: Sort the hierarchical list accordingly to locate the attribute you want to use. If necessary, expand a node to list all the items within the node.
Open the Properties window from the View menu or press F4.
Set the Direction property to a value other than None.
A default text box is placed on the form.
To change the text box to another object type, refer to the instructions in Changing the Object Type.
