Timer suspension/resume
Greetings,
I actually asked this question a week ago and thought that the answer would work, however, I neglected to test it on a midnight rollover. Here is the deal ...
I populate 2 x ComboBoxes with all times from 6:00am, 6:30am etc through to 12:00am. I get the user to select a Suspend time and a Resume time. Let's say that the user wants a Timer to stop at 5:00pm and resume at 6:00am. Entering something like;
If Format$(Now,"hh:nn ampm") > Suspend and Format$(Now,"hh:nn ampm")<Resume then
'Timer_Enabled=False
else
'Timer_Enabled=True
Endif
That code will not work as it does not take the midnight jump into account and therefore, the Suspend time will not be greater. Can someone please point me in the right direction.
Thank you.
Regards,
Tony

you can either store your date in a help variable and check on that too, when the date has changed store the new date, etc.
Or you can test on a datetime value, in which case you can always test on greater then.

Hi!
How about doing something like specifying the number of hours to 'hang' or suspend instead?
With respect to your question, what you can do is something like this: (Remember to declare the sleep Api)
Take note of the indexes (form the combo box) of the suspend time and resume time.
The difference in listindexes would be Resume - Suspend. Thus, you could:
Sleep 30*60*(Resume-Suspend)
'Do the actions :)
That's it!

Hi glass_cookie,
The Sleep API does not work for extended periods. Doing that would cause a "Not Responding" in the TaskList.

Hi tvtech
I hope like that may help
Note : the word Resume is a reserved word so I used REsumetime
Dim SuspendTime As Date, ResumeTime As Date
SuspendTime = Str(Date) & " " & combo1
ResumeTime = Str(Date) & " " & combo2
ResumeTime = IIf(ResumeTime < SuspendTime, 24 + ResumeTime, ResumeTime)
If Now > SuspendTime And Now < ResumeTime Then
'Timer_Enabled=False
Else
'Timer_Enabled=True
End If

Here is a wait function that does not use the API.
Try it and let me know.
Public Sub Wait(HowManySecs As Integer)
On Error GoTo LocalError
' pause for HowManySecs seconds
Dim EndWait
EndWait = DateAdd("s", HowManySecs, Now)
While Now < EndWait
'Do nothing while waiting
Wend
Exit Sub
LocalError:
End Sub

Wend
Exit Sub
LocalError:

You need to take date into account, so best to convert to date type
Dim suspend As String
Dim resumex As String
Dim datSus As Date
Dim datRes As Date
suspend = "05:00 pm"
resumex = "06:00 am"
'work out where the time should fall
datSus = CDate(suspend) + Int(Now)
datRes = CDate(resumex) + Int(Now)
If datSus < Now Then datSus = datSus + 1
If datRes < Now Then datRes = datRes + 1
'*****
then when you do the comparisson
If Now > datSus And Now < datRes Then
'Timer_Enabled=False
Else
'Timer_Enabled=True
End If
Dim suspend As String
Dim resumex As String
Dim datSus As Date
Dim datRes As Date
suspend = "05:00 pm"
resumex = "06:00 am"
'work out where the time should fall
datSus = CDate(suspend) + Int(Now)
datRes = CDate(resumex) + Int(Now)
If datSus < Now Then datSus = datSus + 1
If datRes < Now Then datRes = datRes + 1
'*****
then when you do the comparisson
If Now > datSus And Now < datRes Then
'Timer_Enabled=False
Else
'Timer_Enabled=True
End If
this will assume a midnight rollover when resume < suspend.
i assume that is what you want to achieve.
if resume < suspend then
If Format$(Now,"hh:nn ampm") > Suspend and Format$(Now,"hh:nn ampm")<Resume then
'Timer_Enabled=True
else
'Timer_Enabled=False
Endif
else
If Format$(Now,"hh:nn ampm") > Suspend and Format$(Now,"hh:nn ampm")<Resume then
'Timer_Enabled=False
else
'Timer_Enabled=True
Endif
end if
some recommendations:
- use the date data type to compare times, this is more solid (will work regardless of regional settings...)
- use a checkbox so that users can indicate wether they will be crossing midnight. This allows you to check whether their input is correct.
good luck,

Sorry...
If that causes a 'program is not responding' message, do this instead:
Take note of the indexes (form the combo box) of the suspend time and resume time.
The difference in listindexes would be Resume - Suspend.
At the top:
Dim counttime as integer
In your event,
counttime = (Resume - Suspend)*30
Timer1.Enabled = True
In timer1,
If counttime = 0 Then
'Execute codes
Timer1.Enabled = False
Else
counttime = counttime - 1
End If
That's it!

Thanks Ark. Yours handles the situation exactly as I'd hoped.
Thank you to everyone else for your replies.
Kind regards,
Tony

what you can do with a decision is
if time > suspend time and < resume time and date <> systemdate then
do what every
end if
cheers
