Timer

Use it in a Form#

Click describes activation, while Change describes a value transition. The clock’s running state must follow the checkbox value rather than toggling an unrelated flag each time. Keep timer handlers short and update the display from the current clock value.

Add Timer to the component tray and name it Timer1 for this example:

A complete handler from Forms/frmMain.bas. The linked lesson includes its surrounding controls, declarations and helpers.

Private Sub Timer1_Timer()
    lblLabel1.Caption = Format(Now, "HH:mm:ss")
End Sub

Properties#

Contract defaults are shown below. Where a new control has a different Designer starting value, that value is listed separately.

Events and parameters#

Replace control with the object’s Name when creating a handler. ByRef arguments may be changed by your handler; ByVal arguments report an input value.

Private Sub control_Timer()

Methods#

No methods are declared in this component’s built-in metadata. Use its documented properties and events; do not infer APIs from a similarly named control in another framework.
