Hi,
I'm using vb.net windows form where I'm using a label for displaying a message. I also set a timer for that label (i.e.the display message should disappear within a period of time) with event Timer_Click() but it is not working properly here. Below is the code:

VB

Private Sub Timer1_Tick(ByVal sender As System.Object, By Val e As System.EventArgs) Handles TimerAddLoc.Tick

  If Date.Now - OpenedTime = New TimeSpan(0, 0, 10) Then
    lblErrorMsg.Text = ""
    TimerAddLoc.Enabled = False
  End If
End Sub

[in the top i declared under the Class name : Private OpenedTime As Date ]

Please help me.

Probably my mistake in this comment; it was different question, really unacceptable (Reported to administration as not a question.)

Thats a little too harsh. I totally agree, It's a badly formed question and incomplete.
But, we can see what OP is trying to do something and is unable to express properly.

OP gets my 'benefit of doubt' this time. :)

Sorry, may be I made a mistake in comment...
I really reported such thing, but there was not question at all; and not clue how to assume the question.
Sorry for trouble,

Hey! It's fine. :)

Just looked to me a 'benefit of doubt' candidate, so shared with you.

Unless you don't show us your code we can't help you but only guess and that's just a waste of time. So please, at least post a short snippet of what you wrote.

Solution 1

Timer_Click? Probably a typing mistake.

Look here for sample articles using Timer control in VB.NET:
Working with Timer Control in VB.NET[^]
Timers in VB.NET[^]

Next time onwards, do put in some more effort while forming the question. Just saying as 'Not working properly' is incomplete. Explaining the full behaviour and error if any would surely help.

Solution 2

Hi,

try this:

VB

Private Sub Timer1_Tick(ByVal sender As System.Object, By Val e As System.EventArgs) Handles TimerAddLoc.Tick
  If DateTime.Now >= OpenedTime.AddSeconds(10) Then
    lblErrorMsg.Text = ""
    TimerAddLoc.Enabled = False
  End If
End Sub

What you of course need to do is: When you add the message to the label you need to set the OpenedTime, that means:

VB

OpenedTime = DateTime.Now

5+ - nice and simple

Sergey Alexandrovich Kryukov 26-Jan-11 11:28am

That's good - my 5.
May be some explanation of different times needed: Forms vs System.Times.
The timer in Forms is very inaccurate, not good enough for animation, for example.
