MinTime Property (TDBTime)
Sets/returns the minimum time range.
object.MinTime= variant
Read/Write at run time and design time.
00:00:00 - 23:59:59 (00:00:00 is the default)
The MinTime property is used in combination with the MaxTime property to determine whether the specified time is within the proper range. The value set in the MinTime property cannot be larger than the time set in the MaxTime property.
Generally, the control allows you to enter any valid time while the control has the focus, including times that exceed the MaxTime and MinTime properties. There will be no range checking for the entered time. But as soon as you attempt to move the focus away, the InvalidRange event will be fired notifying the user that the entered time was out of range.
When modifying time values by changing the Value, Number or the Text properties, which are not within the proper range, this will cause an invalid value range error to occur. No events are fired, in this case.
When binding the control to a data source, if the retrieved values exceed the specified range, the DBError event will be fire, returning an error code - 1.
TDBTime.MinTime = "09:00:00"
TDBTime.MaxTime = "18:00:00"
In the above example, time larger and smaller than 09:00:00-18:00:00 would be treated as an error.
If the underlying value contains a Null, the range checking process will be ignored.
The Value property will be automatically set to Null when the current time value does not fall within the maximum and minimum range.
