making backcolor switch back and forth[RESOLVED]

[Andy]

using a timer, how do I code the background color for my group boxes to flash from one color to the next until a condition is met? (mainly, I just need help getting the colors alternating, I have the code to check the condition)

Thanks!!

I figured this much out. It works exactly like I want.

Can anyone think of a better, more efficient way of coding this?

Private Sub tmrGrpCurrentOpen_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles tmrGrpCurrentOpen.Tick
        If grpCurrentOpen.BackColor.Equals(AliceBlue) Then
            grpCurrentOpen.BackColor = Red
        Else
            grpCurrentOpen.BackColor = AliceBlue

        End If
    End Sub

I don't think this is better, but it's different. It might be useful depending on what else is going on in your application.

On balance, I think you should stick with what you've got.

Private tmr As New Timer()
 
    Private Sub Form1_Load(ByVal sender As System.Object, _
                           ByVal e As System.EventArgs) Handles MyBase.Load
        AddHandler Application.Idle, AddressOf Flash
        tmr.Interval = 1000
        tmr.Start()
    End Sub
 
    Private Sub Flash(ByVal sender As Object, ByVal e As System.EventArgs)
        If Now.Second Mod 2 = 0 Then
            grpCurrentOpen.BackColor = Color.Red
        Else
            grpCurrentOpen.BackColor = Color.AliceBlue
        End If
    End Sub
