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)
---
It's amazing to see how much work some people will go through just to avoid a little bit of work.

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

So what's the question? You haven't asked anything, other than implied your looking for permission to do this, in that case permission granted!
What part of this are you having a problem with?

The question still stands. What part of this are you having a problem with??
Is it reading event logs? Writing to a .CSV file? Interpreting the Security events?

Hi
I am unable to Interpreting the Security events?
Can you help me in how to Interpreting the Security events? and generate a CSV file. That CSV file should contain the log entries of only Audit folders.
E.g. if i enable audit logging on a folder in my machine "D:\Temp", then i want a report which should contain the information abt the activities performed in that folder like Creation of file,Deletion of file,Renaming a File and updating a file/Folder.
Format of the CSV/Excel file should be as follows
File | User | Date & Time | Action
D:\Temp\1.txt| Hari | 27-12-2006 | Deleted
Thanks in advance

Sir/Madam,
I am openning a form on the button click.Now the problem is before creating the object of the form to be opened i want to check the form is already opened or not.
Thanks and Regards

What are you using to trigger the creation of your second form? What are you using to show your form? Are you calling .Show() or are you calling .ShowDialog()??
If you're using .Show, you'll have to keep track of the instance of the form that you created. When you go to attempt to create the second instance of that form, check the variable you're using to track the new form. If it's not Nothing, then you can create a new instance of the form.
The problem comes when the new form closes. You have to listen for the form's FormClosing event so you can track that the form is in the process of closing. You can use this opportunity to retrieve any data you need off of that form before it dies completely.
Public Class Form1
Private OpenForm As Form2
Private Sub Button1_Click(blah, blah) Handles Button1.Click
If OpenForm Is Nothing Then
OpenForm = New Form2
AddHandler OpenForm.FormClosing, AddressOf OpenForm_FormClosing
OpenForm.Show()
End If
End Sub
Private Sub OpenForm_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs)
RemoveHandler OpenForm.FormClosing, AddressOf OpenForm_FormClosing
'
' Get any data you need from the form here...
'
OpenForm = Nothing
End Sub
End Class

mind if i suggest some VB6 alternative - i've yet to master .net so i don't really know if this works, but...
in vb6 i would do this
If formWhatever.Visible = True Then
Msgbox "Form already visible!"
Else
formWhatever.Show
End If
|
|
|
|
|
That won't work in VB.NET because Forms work VERY differently than they did in VB6. In VB6, every form was already instantiated and visible from anywhere in your code. This is no longer the case in VB.NET since forms are actually classes and you have to instantiate them yourself.
