Best way to convert total minutes into HH:mm format?

Question

I get a return value from a web service in minutes, for example 538 minutes. I need to break this down in hours and minutes. What is the fastest way, in .net code and also VB6 code (two apps use the service) to convert this from minutes to HH:mm?

Thanks

Answer 1

This code should work both in .NET and VB6:

Dim hours As Integer = 538 \ 60
Dim minutes As Integer = 538 - (hours * 60)
Dim timeElapsed As String = CType(hours, String) & ":" & CType(minutes, String)
label1.Text = timeElapsed

In .NET exclusively, you should be able to do the following (which requires to be tested):

Dim timeElapsed As DateTime = New DateTime(1, 1, 1, 0, 538, 0)
label1.Text = timeElapsed.ToString("HH:mm")

I hope this helps!

Answer 2

In VB6 you could just use Format(538/1440.0, "hh:mm")

VB6 Date values can be treated as a number of days, and there's 1440 minutes in a day. So 538/1440 is the number of days in your period, and then you can use Format
