Question on timer class

Hi everybody

I would like to ask a question on timer class........for example, the user clicks on the button, the timer starts to count for 1 sec and then i wish to hv a msgbox emerge to tell the user "no response" immediately after the 1 sec....... i would be appreciated if anyone can help me.......thank u very much


Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnRx.Click

End Sub

VB Code:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnRx.Click
    Timer1.Interval = 1000
    Timer1.Enabled = True
    'Do something if they respond ???
    '
    'If they respond in time turn off the timer?
    Timer1.Enabled = False
End Sub
 
Private Sub Timer1_Tick(ByVal sender As Object, ByVal e As System.EventArgs) Handles Timer1.Tick
    MessageBox.Show("Times Up!", "Timer")
End Sub

Something similar to this.

HTH

add a timer at design time, click on it and in properties set the interval to 1000 (milliseconds= 1 second).

VB Code:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Timer1.Enabled = True
    End Sub
 
    Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
        MsgBox("boo")
        Timer1.Enabled = False
    End Sub

But if they respond in the time allotted then the timer will still fire.

putting code in that commented area in button_click wont do anything unless he has an infinite loop, which is inefficient anyways

True :D, but I didnt know what other actions the poster had in place while he was waiting for a response.
Like an event for entering text in a textbox and pressing another button?

:p

hi Everybody

Thanks for the reply.....i'm have actually written a download process after the Timer1.Enabled = True and i wanted the timer to turn off if the download process complete on time.............but now.....i get this error "Handles clause requires a WithEvents variable"......what does this mean? can any 1 tell me this? thank u very much



Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnRx.Click
Timer1.Interval = 1000
Timer1.Enabled = True

'Do something if they respond ???
'
' If they respond on time turn off the timer

Timer1.Enabled = False

End Sub

Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
MessageBox.Show("Time out !!", "Timer")
End Sub
End Class

that's probably because you copy/pasted the code hehe
You need to declare a variable first before you can reference an event for it. You can either do it manually, which I dont think would be easy for you..... .or

umm do this: you probably already have the button so the error should be from the timer. In design view of your form, add a TIMER control to your form and then double click on the timer. VS.NET will automatically generate the code for Timer_Tick event for you. Then you can put your timer code in there.
