Excel application ontime code#

Returns a valid time from a String expression Example: TimeValue('8:27:28') returns #8:27:28 AM# as type DateĪdding a clock as a Worksheet name is unusual, and also makes subsequent code referring to the sheet by name virtually impossible. Returns the number of seconds since 12:00 AM on the current system time Example: Timer returns 30448.51 as type Single Returns the current system time Example: Time returns #8:27:28 AM# as type Date Returns the integer value for the second 0 to 59 Example: Second(TimeValue('8:27:28')) returns 28 as type Integer Returns the current system date and time Example: Now returns # 8:27:28 AM# as type Date Returns the integer value for the minute 0 to 59 Example: Minute(TimeValue('8:27:28')) returns 27 as type Integer

Returns the integer value for the hour 0 to 23 Example: Hour(TimeValue('8:27:28')) returns 8 as type Integer Returns a date from String Example: DateValue('3-June-2018') returns # as type Date Returns the current system date Example: Date returns # as type Date Selected Date and Time functions VBA function This avoids a one second initial lag if the loop started at CapClockTick point.įig 2: Clock loop - if we start at CapClock (line 12), code line 15 calls CapClockTick (line 5), that waits for one second before calling CapClock in line 8, and the loop continues. Both the Workbook Open event and the on-sheet control run the CapClock procedure. The loop between the Clock and ClockTick can be seen in figure 2. The clock is updated at one second intervals as set by the Const OneSec As String = '00:00:01' in line 2 and EarliestTime:=Now + VBA.TimeValue(OneSec) in line 14.Ĭode 1: CapClock add a digital clock to the Application.CaptionĪpplication.Caption = Format(Time, 'hh:mm:ss AM/PM')ĮarliestTime:=Now + VBA.TimeValue(OneSec), _ Click image to enlarge.Īdding a clock to the Application.Caption in code 1 line 7.

A ClockClear procedure to break the loop between the procedures in points 1 and 2.įig 1: xlfAnimation :: WS Clocks - 1.

It is important to understand that the Clock and ClockTick have a circular link and form a two procedure loop (see figure 2)

One second is the smallest time interval available in the VBA language environment. This runs the Clock at regular intervals one second time steps in this case. A ClockTick procedure linked to the Clock procedure.A Clock procedure linked to a ClockTick procedure.The AppCap clock is also fired by the Workbook Open and BeforeClose events. Procedures can be run and stopped from on-sheet ActiveX controls. Five examples are shown in figure 1, and the code is provided in sections 1.1 to 1.5. The following example use the Application.OnTime method to control a number of clock interfaces.

Returns True if the specified time has arrivedĮxample 3: run the M圜ode procedure in 30 seconds from now - If Application.Wait(Now + TimeValue('00:00:30')) Then Call M圜ode Syntax Application.Wait method: (not part of this module) This example is similar to the Wait method False to clear set procedureĮxample 1: run the M圜ode procedure at 6:15 pm - Application.OnTime TimeValue('18:15:00'), 'M圜ode'Įxample 2: run the M圜ode procedure in 30 seconds from now - Application.OnTime Now + TimeValue('00:00:30'), 'M圜ode'. True (the default) to schedule a new procedure. If set, a procedure will not be run if both the EarliestTime and LatestTime have passed If omitted the, the application will wait until the procedure can be run. The name of the (sub) procedure to be run Application.OnTime(EarliestTime, Procedure, LatestTime, Schedule)
