- 0 for the memos.
<Data file>: Character string Name of the data file used. This name was defined in the data model editor or with the File Description type. <Item>: Character string Name of the item used. This name was defined in the data model editor or with the Item Description type.If this item is a text item, number of characters in the item. If this item is a time item, the number of characters is used to identify the item format: | | Number of characters
in the Time item | Format of Time item |
|---|
| 2 | HH | | 4 | HHMM | | 6 | HHMMSS | | 8 | HHMMSSCC | | 9 | HHMMSSCCC |
Remarks Number of characters If the maximum number of characters that was specified is less than the number of characters currently found in the control: - The content of the control is not modified on the screen.
- The value of the control includes all the characters displayed in the control.
Multiline edit control If the maximum number of characters allowed in a multiline edit control is changed with the Size property, you will be able to assign a text containing more characters than the number that was defined. For example:
// "EDT_Address" is a multiline edit control
EDT_Address.Size = 5
EDT_Address = "ABCDEFGHI"
// "EDT_Address" contains "ABCDEFGHI"
Control with input mask The Size property must not be used to change the maximum number of characters in controls with an input mask. Indeed, the maximum number of characters found in the control depends on the input mask defined for this control. Limitations In HFSQL data files, the Size property applies only to text and time items. In a report, the Size property can only be used on Static controls.
