Control of negative time expression formatting

[matt beamish]

Hello folks.
I am using a little explanation posted by Allen Browne (here http://allenbrowne.com/casu-13.html on expressing minutes as hours and minutes, and I have written this little function:

Function Calc_HrsMins(TotalMinutes As Variant) As Variant
On Error GoTo calc_hrsmins_error
Dim varHours, varMinutes
varHours = Int(TotalMinutes \ 60)
varMinutes = Format([TotalMinutes] Mod 60, "\:00")
Calc_HrsMins = varHours & varMinutes

Exit_Calc_HrsMins:
   Exit Function

calc_hrsmins_error:
MsgBox Err.Number & Err.Description
Exit Function

End Function

if my value is negative, I get these results:
TotalMinutes = -500, -8-:20
TotalMinutes = -5, 0-:05

I would like to suppress the negative symbol for the minutes and always show it for the hours, even if the hours are 0, so text boxes display -8:20 and -0:05 respectively.

I think this is going to be by using a series of IIfs, but I dont know how best to suppress the negative...multiply it by -1?

Any advice please?

thanks in advance

suggest try using the abs function

varMinutes = Format(abs([TotalMinutes]) Mod 60, "\:00")

Thanks very much for your reply, I will give this a try tonight.

varHours = Abs(Int(TotalMinutes \ 60))
varMinutes = Format([TotalMinutes] Mod 60, "\:00;\:00")

To get what I needed, to suppress the double negative symbol but to show a negative if the hours = 0 and minutes = < 0 I ended up with this:

Option Compare Database
Function Calc_HrsMins(TotalMinutes As Variant) As Variant
On Error GoTo calc_hrsmins_error
Dim varHours, varMinutes

varHours = IIf(Int(TotalMinutes \ 60) = 0 And (TotalMinutes Mod 60 < 0), Format(Int(TotalMinutes \ 60), "-0"), Int(TotalMinutes \ 60))
varMinutes = Format(Abs([TotalMinutes]) Mod 60, "\:00")


Calc_HrsMins = varHours & varMinutes

Exit_Calc_HrsMins:
   Exit Function

calc_hrsmins_error:
MsgBox Err.Number & Err.Description
Exit Function

End Function

Hi there, don't know if till relevant but I found an easy workabout:

If guthabenrecs!Endwert > 0 Then
Me.guthaben_std = (Me.Guthaben * 1440) \ 60 & Format(Me.Guthaben * 1440 Mod 60, "\:00")
Else
Me.guthaben_std = (Me.Guthaben * 1440) \ 60 & Format((0 - Me.Guthaben) * 1440 Mod 60, "\:00")
Me.guthaben_std.ForeColor = 255
End If


Just putting a 0 - theAmount in the minutes section
