Hi,
I need to use a Timer at run time. I have created a Timer
class which has method 'CreateTimer'.
I am able to create a timer and run the associated event
(code snippet follows), but I am unable to:
1. Stop this timer.
2. Give it a specific Name (sTimer), so that I can
control its interval dynamically.
Can you Please point out what I am missing in my logic ?
Public Function CreateTimer(ByV al sTimer As string)
Dim TB As Timer
Try
TB = New Timer
TB.Enabled = True
TB.Interval = 3000 '3 seconds delay
TB.Start()
AddHandler TB.Tick, AddressOf TimerEvents01
....
End Function
Private Sub TimerEvents01(B yVal sender As Object, ByVal e
As EventArgs)
Msgbox "Testing" & Now
End Sub

$a*******@phx.g bl: 1. Stop this timer.
Why can you set the timer's Enabled property to False?
2. Give it a specific Name (sTimer), so that I can control its interval dynamically.
Public Function CreateTimer(ByV al sTimer As string)
It looks like you have forgotten to set your return type. If you want to
return the timer from the code:
Public Function CreateTimer(ByV al sTimer As string) As Timer
Dim TB As Timer
Try
TB = New Timer
TB.Enabled = True TB.Interval = 3000 '3 seconds delay TB.Start() AddHandler TB.Tick, AddressOf TimerEvents01
I would recommend setting the handler BEFORE enabling the timer. ....
End Function
Private Sub TimerEvents01(B yVal sender As Object, ByVal e As EventArgs)
Msgbox "Testing" & Now End Sub
Make sure you have Option Strict On

What do you expect the function to return?
Dim TB As Timer
Try
TB = New Timer
TB.Enabled = True TB.Interval = 3000 '3 seconds delay TB.Start() AddHandler TB.Tick, AddressOf TimerEvents01
....

Msgbox "Testing" & Now End Sub
Don't know if it helps:
Private m_Timer As Timer
Sub CreateTimer()
m_Timer = New Timer
m_Timer.Interva l = 3000 '3 seconds delay
m_Timer.Start()
AddHandler m_Timer.Tick, AddressOf TimerEvents01
End Sub
Sub KillTimer
RemoveHandler m_Timer.Tick, AddressOf TimerEvents01
m_Timer.Stop
End Sub
Maybe you also want to add a Name property:
Public ReadOnly Name As String
Public Sub New(ByVal Name As String)
Me.Name = Name
End Sub

Hi Vinay,
Take a look at Timer which Timer you are using, there are at least 3 and
they are all very different
Microsoft.Visua lBasic.Timer
Windows.Forms.T imer
System.Threadin g.Timer
I thought that the last one was almost not to stop because he has his own
thread
(I am not sure of that)

I would recommend setting the handler BEFORE enabling the timer.
I wanted to suggest the same but as it is a System.Windows. Forms.Timer, the
first tick event does not occur before the app is idle, so it's not really
required to add the handler before.

Hello,
Wow...I have one for you all and hopefully I am not understanding this timer
object correctly. I have a timer setup that pulses a connection through a
socket every 60 seconds. But it seems recently connections just drop off
because the timer stops firing.
My question is if there is a timeout in the timer event that just shuts down
the call if the timer event is taking too long to complete...?

I have created an array of timers (1-n). At first I just created
windows form timers but I read that system timers are better for
background work. The timers will just be monitoring different
directories and updating a database. No interaction with the GUI.
Problem is that the system timers do not have a tag property so I can
tie in an object.

I need some help here, I have a form on which I have all the user interface components, and I need to do a big calculation every 5 seconds. I used the Timer object to do this calculation every 5 seconds.
