Hi Nicolas
Don't use a Date data type for your field. This is for recording a specific
date/time, not an elapsed time. I suggest using a decimal data type and
entering your elapsed time as a fractional number (eg 1.5 hours) or as an
integer (eg 90 minutes). Get your users to enter it as 1.5 or 90 etc. If
necessary you may have to have it entered in two fields, hours and minutes
(e.g 1 hour and 30 minutes).
For reports, have a function for formatting it correctly. For example,
displaying 90 minutes as '1:30'.

Hi all,
Like Nicolas, I am not a programmer but reading through the posts here
everyday, it seems that people can do pretty much anything they want with
the correct know-how and desire. It's been a long time since I was at school
so forgive me if I am not accurate but normal numbers are in base 10 (or
100) and time is in base 60? Is there not a way that the user can tell
Access to calculate a decimal data type in base 60?
Just a thought,
Mark

As Jeff says don't use the Date function, try using the "\" and
"Mod" operators.
For example I have a form which shows music CD tracks; for each
track its length is entered as minutes and seconds in separate
fields. The query it is based on has a calculated field:
TrackLength: [tracklengthmin]*60+[tracklengthsec]
Total length is given in two controls on the form:
Minutes control source =Sum([tracklength])\60
Seconds control source =Sum([tracklength]) Mod 60
This isn't the same problem as yours but it could be modified to
give hours and minutes. nm*****@hotmail .com (Nicolas Mejia) wrote: Hello:

No. Not unless I have missed something here for a long time. But the code is
simple. This function below is air code but should work okay. You may want
to add error trapping.
Function FormatElapsedTi me(plngTotalMin s as long) as String
Dim lngHrs as Long, lngMns as Long, strTime as String
lngHrs = Int(plngTotalMi ns / 60)
lngMns = plngTotalMins Mod 60
strTime = Format(lngHrs, "00") & ":" & Format(lngMns, "00")
FormatElapsedTi me = strTime
End Function

You didn't give us any information about your table structure, but if you
are looking to calculate the number of hours or minutes between two
date/time values you need to use the DateDiff() function. : This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics | |

I have the following problem, and I would be extremely grateful if

I create an instance of a Class A, and "push_back" a copy of this into a

Ok whenever I "push_back" a copy of Class A, I also want to assign a
