in VB.net (not sure about 6...)

a timer with the interval of 1000 = 1000ms which = 1 s

so for 1 minute 60 * 1000 = 60,000

so for 5 minutes 60 * 5000 = 300,000

 

[Sankalp]

You can assign the interval of your timer on form load to some value.
e.g. if your timer is Timer1, then
on form load :-
Timer1.Enabled = True
Timer1.Interval = 300000 ( 5 minutes)

This will fire the Timer1_Elapsed event where you can do your
processing.

in VB.net (not sure about 6...)

a timer with the interval of 1000 = 1000ms which = 1 s

so for 1 minute 60 * 1000 = 60,000

so for 5 minutes 60 * 5000 = 300,000

In VB6 the timer control is limited to 65535 so the usual method there is to
save the time ina module-level or static procedure level variable, set the
timer to 60000 (or any value >0 and <65536) and then when the timer event
fires compare "Now" to the saved time to determine if you have reached the
desired interval.

Timer1.Enabled = True
Timer1.Interval = 300000 ( 5 minutes)

Not in ClassicVB, you can't!

perhaps its time for an upgrade?

Not in ClassicVB, you can't!

Ah yes, if only there were... (Signed the petition, yet? ;-)

Nah... you'll find out the first time that 5 minutes is up and the OS has
swallowed a timer event <g>

Personally, I set the tick to about once per second (depending on a few
things) and use DateDiff to figure out if a certain amount of time has
elapsed. Timer events are just to flakey to rely on. By doing the math
myself, I eliminate the OSs ability (for the most part) to ruin my timing.

Exactly. Two languages, two answers.

 

[PulsarSL]

dim interval as long
dim ticked as long

long = 30000 'or your time, in seconds
ticked=0

Private Sub Timer1_Timer()
ticked = ticked + 1
if ticked = interval then call yourfunction
end sub

long = 30000 'or your time, in seconds
ticked=0

Private Sub Timer1_Timer()
ticked = ticked + 1
if ticked = interval then call yourfunction
end sub

Yeah, that's one idea (though I'd use Static procedure vars, myself), but as
others have pointed out this method is vulnerable. You are hearby
admonished to write, 1000 times, on the blackboard:

"Windows is not a real-time operating system."
"Windows is not a real-time operating system."
"Windows is not a real-time operating system."
"Windows is not a real-time operating system."
"Windows is not a real-time operating system."
"Windows is not a real-time operating system."

I usually set the Interval to 60000 (1 minute) and use the Timer's Tag
property as a minute counter:

Private Sub Timer1_Timer()
If Val(Timer1.Tag) < 4 Then
' Increment minute counter
Timer1.Tag = Val(Timer1.Tag) + 1
Else
' Do actual stuff every 5 minutes

' Reset minute counter
Timer1.Tag = "0"
End If
End Sub

Tark,

In VBNet in at least 3 (4) different methods. This dependend if you use it
for a Form, a windowsservice or a multithreading application. For Webforms
will in the Atlas part as well a clientside timer be included.

Beside that can you in windowforms VBNet as well stop the processing one
minute or longer and get mostly the same effect.

I hope this helps,

Cor

Yuk!

For VB (not B#) I would set the interval to about 1 sec or less

and set up module variable as :-

TargetTime = DateAdd( "n", 5, Now )

In the Timer Tick just check for

If Now >= TargetTime Then ...

 

[Rich M]

LOL - it works

Yuk!

[Bob Butler]

LOL - it works

Except that it really doesn't. With the vagaries of the timer firing it
tends to drift further and further from the desired intervals. Checking Now
against a target time keeps it more accurate over a longer time span if
that's important.

 

[Saga]

And no loops of any kind can be used! <eg>

It does work but the complexity of what happens underneath is quite large.
It will do something like this:
- Retreive the timer.tag as a string
- Val will convert that to double
- the 1 is a 16bit int and will be converted to a double
- add the 2 together as doubles
- convert the result back to a string
- put the result back into the timer tag

on the other hand incrementing a module level variable will simply do an
increment which will be a single cpu instruction (the above would be
literally hundreds). While I don't think it's worth concerning yourself
overly with this sort of thing it is worth taking into account and not
writing inefficient code just because it's the same amount of typing. Once a
project got large if this sort of thing was used throughout it could bloat
it considerably.
