I have an array of objects. Each object refers to an mp3 file as follows:
mp3file.Title
mp3file.Artst
mp3file.Album
mp3file.TrackNumber
My question is, how can I sort the array by a specific item of the object, eg. Sorted by Artist, sorted by Album etc.

Make a custom comparer for your class, and use that in a call to Array.Sort.

Thanks for the quick reply.
You say, 'Make a custom comparer for the class'. I'm fairly new to VB.net and don't quite understand what you mean. Please could you explain a little more.
Thanks again

Something like this. Say you want to sort by Artist name.
Make a function:
Function CompareArtist(ByVal Artist1 As String, ByVal Artist2 As String) As Boolean
IF (Artist1>Artist2) Then
Return True
Else
Return False
End IF
End Function
Then when you do your sort, have something like this:
If CompareArtist(mp3file(1).Artist,mp3file(2).Artist) Then
//Do you sorting here depending on the result of the compareartist function.
End If
You could make a seperate comparison function for each member of the object, or just 1 or 2 depending on the type's of the object's members (if they are all strings for example). I hope that makes some sense.

Thanks very much, this is the sort of thing I was after.
I guess you cant use array.sort on an array of objects. I though there was probably some syntax you could add into array.sort to specify which 'column' you wanted to sort by.
Anyway, the code you have given me David looks fine. Thanks

Create a class that implements the interface IComparer. The class needs to have a method named Compare that does the comparison of the properties you want to sort.
I usually don't program VB, but something like this:
Class MyObjectComparer Inherits IComparer
Public Function Compare(A as Object, B as Object)
Return String.Compare(DirectCast(A, MyClass).SomeProperty, DirectCast(B, MyClass).SomeProperty)
End Function
End Class
This you can use to sort your array of MyClass objects:
Dim comparer as new MyObjectComparer()<br />
Array.Sort(TheArray, comparer)

hi..
i need help with rounding decimals to nearest 10th.
e.g
$1.20,$1.21 & $1.22 rounded 1.20
$1.23,$1.24 rounded to $1.25
$1.26 , $1.27 rounded to $1.25
$1.28 , $1.29 rounded to $1.30
hope this above example is an idea of what i need.
thanks

Multiply by 10, round it (integer rounding), and then divide by 10?
|
|
|
|

hi chandra
can you give me a quick sample source.
Robbo
|

Chand
an a sample like this. the end result always rounds down
e.g. dim num as decimal = 1.23
dim roundednum as integer
roundednum = math.round(num *10)/10
'result = 1.2 instead of 1.25
Robbo

But that is what you wanted, right? Round to nearest 10th?
Btw, my name is Chandra

i think my first message was right except i said 10th which gave a confusion.
basically i need decimal rounded down or up to nearest decimal
e.g 1.20 ,1.21,1.22 should be $1.20
1.23,1.24,1.25 should be $1.25
1.26,1.27 should be $1.25 (round down here)
1.27,1.28,1.29 should be $1.30
btw. i know your name is Chandra was just giving you a short nick thats all.
sorry if that offended you.

My bad - I did not study the examples, just went by your statement 
What you want is round to nearest 5 cents...
Ok, try this then:
x = round(x * 20) / 20
