i'm wondering how to get the length of a track in HH:MM:SS.  i'm using c#, and all the examples i've seen are in vb or delphi.  i'm using the BASS_ChannelBytes2Seconds method and it gives me the seconds in a double, but how do you convert that to minutes and seconds, without a decimal remainder? 

as a side note, how do you bind a trackbar to move to a specific time? 

[faggus]

after thinking about this, i guess it's too broad.  is there a way to use DateTime() in c# to convert the double to mm:ss?  and how do you guys have your time update itself as a label or text?  do you use a for loop?

You can convert the seconds (as returned by BASS_ChannelBytes2Seconds) to a TimeSpan instance like this:

TimeSpan ts = TimeSpan.FromSeconds(length);

To convert seconds to a DateTime value you must first create a new DateTime instance with no hour/minute/second portion and then add the seconds:

DateTime dt = DateTime.Today;
dt.AddSeconds(length);

You might also want to use the "Utils.FixTimespan" method to convert the seconds to a printable string (see the docs for more info).

How do you update the text, a loop?  Is there an inherent method that updates it without stealing resources?

[radio42]

You can use a timer event to update the text frequently.
Please take a look to the provided samples that come with BASS.NET.

HoW would you use that with a trackbar slider?  Can you show me an example?

Look here: http://www.un4seen.com/forum/?topic=4083.msg27422#msg27422
Or take a look to the provided C# samples.

yeah, i've seen that thread before, except that it doesn't work for me.  i'm using wpf, and i need to update a label and the trackbar.  could i use dispatchertimer? is there an example around using that?

I am not using WPF much, so I don't have any WPF samples available.

In WPF you need to use a "DispatcherTimer" for showing position on a label or textbox, otherwise you get threading problems.

i got it to work with dispatchertimer.
