Published: July 16, 2012
This example shows how to make cell B2 on sheet 1 blink by changing the color and the text back and forth from red to white in the StartBlinking procedure. The StopBlinking procedure shows how to stop the blinking by clearing the value of the cell and setting the ColorIndex property to white.
Option Explicit Public NextBlink As Double 'The cell that you want to blink Public Const BlinkCell As String = "Sheet1!B2" 'Start blinking Private Sub StartBlinking() Application.Goto Range("A1"), 1 'If the color is red, change the color and text to white If Range(BlinkCell).Interior.ColorIndex = 3 Then Range(BlinkCell).Interior.ColorIndex = 0 Range(BlinkCell).Value = "White" 'If the color is white, change the color and text to red Else Range(BlinkCell).Interior.ColorIndex = 3 Range(BlinkCell).Value = "Red" End If 'Wait one second before changing the color again NextBlink = Now + TimeSerial(0, 0, 1) Application.OnTime NextBlink, "StartBlinking", , True End Sub 'Stop blkinking Private Sub StopBlinking() 'Set color to white Range(BlinkCell).Interior.ColorIndex = 0 'Clear the value in the cell Range(BlinkCell).ClearContents On Error Resume Next Application.OnTime NextBlink, "StartBlinking", , False Err.Clear End Sub
