When you remove an item from a collection, everything above that index number moves down one. So, in your example, when you removed index 1, the items at 2 and above moved down.
Instead of removing every index, count them and remove the first one every time:
a.Add("s")
a.Add("s")
a.Add("s")
a.Add("s")
a.Add("s")
a.Add("s")
For i As Integer = 1 To a.Count
a.Remove(0)
Next

The easiest way to clear a collection is to put a.Clear(). You should always hit the dot and look through the intellisense if you're not sure if a method is supported. Assuming you were actually stepping through trying to remove specific items, step backwards like this ( sorry C# code, I dunno the VB syntax ):
for(int i = a.Count-1;i>=0;--i)
{
if (a[i] == "ThevalueIwanttoREmove")
{
a.RemoveAt(i);
}
}
That way, the indexes that change are all in the range I've already stepped through.
Note also that your loop cannot work, arrays are 0 indexed, not 1 indexed. a(0) is the first element, a(1) is the second.

you mean this ?
For i As Integer To a.Count - 1 Step -1
If a(i) = "TheValueIwantToRemove" Then
a.RemoveAt(i)
End If
End For
another much apreciated VB code would be :
For each Ob As Abject In a
a.Remove(Ob)
End For
or even better :
a.clear()

Yeah - the step was the part I was not sure of, and I'd prefer to say so than give code that turns out to be syntactically wrong.

a.clear()
Yeah, I did actually point that out as well

It's impossible fo us to tell you anything about how to do this because we know nothing of how your authenticating these people and tracking their login/logout.

The Form properties has an "Icon" property that you can use to specify a file with an icon image. You can also compile an image if you use ImageList object which is available from the Toolbar. Following is an example to get image at index 0 from imagelist and set it as an icon:
<br />
Dim bm as Bitmap = New Bitmap(myImageListObject.Images(0))<br />
Me.Icon = Icon.FromHandle(bm.GetHicon())<br />

i m developing a media on demand system, which is an ASP.NET Web Application..
1) how to use login n logout in a multiuser environment ? i think we need to implement cookies, but dunno how to use them.. ?
2) in our web application, the client can play media(audio/video) files on his web page. on the server side, i ve embedded the windows media player on the VB.NET interface... and passing the URL of the media files dynamically to the windows media player...
but if the client has Download Accelerator Plus, when he selects the file to play, the DAP(Download Accelerator Plus) pops up and start downloading these media files... how to disable this DAP from downloading the files on the client's system ?
please help me... i need it badly

1) Your questions belong in the ASP.NET Forum since your working on an ASP.NET application. It don't matter what language you're writing it in.
2) If the client has this, you can't do anything about it! ASP.NET is a server-side only technology that generates HTML pages for a browser. If there was some JavaScript way of doing it, great!, I have no idea what it is, or if it's even possible.

as per your two points...
1. I suggest you to use session variables as cookies could be disabled by the client side and in that case your application will not work. So worry about sessions. not for cookies..
2. As far the download accelarator is concerned it is its default behaviour to accept all in coming files other then related to web like htm,asp,jpg etc . I am not sure that you would be able to find any solution for this...I suggest you to use real player as it supports streaming and this might help you...
best of luck

Hi all,
I want to disable functionality of mouse wheel in my application. I don't want the front end's scrollbars to scroll if user uses the mouse wheel.
Does any one how to do that. I would sincerely appreciate your help.
Thanks,

Catch the mouse wheel windows message, don't pass it to the base class, and ignore it. If that doesn't work, catch the pretranslatemessage message, and kill it there.
