EntryField Class
The EntryField class represents a field into which the user can enter data. Depending on the data type defined for the field, the data can be character, numeric, or date. An entry field can display either a single line or multiple lines for user entry, depending on the setting of the IsMultiLine attribute.
A single-line entry field:
Can have an associated variable of any valid scalar type
Allows the data in the fields to scroll horizontally
Considers newline and tab characters as field exit commands
Note:  If a default button is defined for the frame, then a newline character executes the event block for the default button. The user may or may not exit the field, depending on the code in the event block.
Supports the use of format templates to control data entry
Does not require a toolkit control to be associated with it
Unless a toolkit control is associated with the field, it always displays at the bottom of the field stack unless it has the input focus. When the field has the input focus, it appears at the top of the field stack until focus is removed. This behavior can be changed by setting the RequireRealField Attribute, which associates a toolkit control with the field.
A multiline entry field:
Can have an associated variable only of the varchar or StringObject data type
Scrolls the data in the field vertically
Automatically provides word wrap
Considers the newline and the tab as valid input to be included in the text and counted as characters
Allows large amounts of text
Provides an extended keyboard interface, following

To leave a multiline entry field, the user can use the mouse to click another field, use Ctrl+Tab to go to the next field in the tab sequence, or use Shift+Tab to go to the previous field in the tab sequence. All entry fields let the user select and delete text using the mouse.
When you use a StringObject value in association with an entry field, you must use the UpdField method (inherited from ActiveField) on the field to display any runtime changes to the field.
