.NET Forum / .NET Framework / General / December 2005Convert seconds to 00:00:00 (HH:MM:SS) format. Please help
I have this for example: Dim iSeconds as int32 = 3600 '3600 seconds is one hour How do i convert it to "01:00:00" ? Please help. Thanks in advance! Perhaps Dim iSeconds As Int32 = 3600 Dim ts As New TimeSpan(0, 0, iSeconds) MsgBox(ts.ToString) /JB >I have this for example: > >Dim iSeconds as int32 = 3600 '3600 seconds is one hour >How do i convert it to "01:00:00" ?

The ToString method of the TimeSpan object does not take a format parameter, so it would still be Dim span As TimeSpan = TimeSpan.FromSeconds(iSeconds) MsgBox(span.ToString()) But you are right: .FromSeconds is a more appropriate answer to the original problem (though it looks as if FromSeconds requires quite a bit more work to be performed under the covers). Ah, I'm just nit-picking. Have a look at the ToString function below (from Reflector). A shorter, faster version could be written by hand to deal with the specific requirement, but the formatting is the same as what the original poster wanted: ---snip--- Public Overrides Function ToString() As String Dim builder1 As New StringBuilder Dim num1 As Integer = CType((Me._ticks / 864000000000), Integer) Dim num2 As Long = (Me._ticks Mod 864000000000) If (Me._ticks < 0) Then builder1.Append("-") num1 = -num1 num2 = -num2 End If If (num1 <> 0) Then builder1.Append(num1) builder1.Append(".") End If builder1.Append(Me.IntToString(CType(((num2 / 36000000000) Mod CType(24, Long)), Integer), 2)) builder1.Append(":") builder1.Append(Me.IntToString(CType(((num2 / CType(600000000, Long)) Mod CType(60, Long)), Integer), 2)) builder1.Append(":") builder1.Append(Me.IntToString(CType(((num2 / CType(10000000, Long)) Mod CType(60, Long)), Integer), 2)) Dim num3 As Integer = CType((num2 Mod CType(10000000, Long)), Integer) If (num3 <> 0) Then builder1.Append(".") builder1.Append(Me.IntToString(num3, 7)) End If Return builder1.ToString End Function ---snip--- /JB "Michael Barrido" <jmmrb@hotmail.com> schrieb: > Dim iSeconds as int32 = 3600 '3600 seconds is one hour > How do i convert it to "01:00:00" ?

So, I thought I would add the "tt" to help. >james No, that is not quite enough: The "tt"-specifier depends on the current culture. On my machine (English XP, but with default Danish regional settings), there are no AM/PM symbols, so the suggested "hh:mm:ss tt" would not provide complete time information on my system. I would just see something like "11:59:00 " (yes, including the trailing space). At the very least, make sure that the requirements for using "hh:mm:ss tt" are fulfilled, i.e. that AM/PM designators have been specified for the current culture. For completeness sake: hh = 12-hour format (1-12). HH = 24-hour format (0-23). Be careful not to write MM (month) instead of mm (minute). For more information, see "Custom DateTime Format Strings" in the documentation.

I have read up on the "Custom DateTime Format Strings", since Chris had given me the help that I mentioned in my post.

Herfried, sorry about that. I didn't realize that the original poster was wanting to display a passage of time. My intent was not to cause a problem. I have been working on an old DOS based , database system conversion and the original database engine stored the time of day in seconds. I had posted a question here some time back on how to convert those seconds back to a readable time format including AM/PM and Chris had helped me with that. For some reason, I thought the original poster had been looking for a similar solution. I guess that is what happens when I have not had my full 3 cups of coffee before reading and responding to posts!!! james >Herfried, sorry about that.

[quoted text clipped - 5 lines] >full 3 cups of coffee before reading and responding to posts!!! >james 's okay. The discussion took another direction because the Date object and its ToString formatting options was suggested. My replies (and yours) were to the specifics of those posts - not to the problem of the original poster. I knew that we had gotten off the track. No harm in that. As long as it is clear that those replies are not specific to the problem outlined in the original post. I sometimes throw something out there which might only be 80% correct (e.g. something that works, turns out to be more easily done another way). No harm in that *provided* someone else steps in and offers the 100% solution. When I had my Hex->Integer problem, I was happy to be informed that Integer.Parse could handle it correctly. But even happier when Armin suggested "System.Convert.ToInt32(hexvalue, 16)" which was exactly what I needed. Sometimes the Devil is in the details, but if the first replies to any questions had to be 100% perfect, we might as well close the group now. If, however, we help each other out, we'll eventually get there. /JB James, As it says AM/PM is only where the English language is used. And simply enough use other languages 24hours clocks. Although the way we say it by instance in Dutch is almost the same as in English. 20:00 is acht uur s'avonds (eight O'Clock in the evening) :-) Cor > James, > [quoted text clipped - 9 lines] > > Cor Cor, of course you are correct. I should have not answered the original post without having a better understanding of what the original poster was trying to achieve. And what his requirements were. I'll try not to respond to posts unless I have had my full quota of coffee from now on. :-) james Free MagazinesGet these publications absolutely FREE for up to 12 months.
