Taskbar, Finding Files & Storing Data

Hi, three questions:

1) I have a form that has no border (BorderStyle = 0) so I can customise it's whole appearance, but with no border it doesn't show on the taskbar, or in the alt+tab popup, how can I fix this without giving my window a border?

[ EDIT : Fixed this, "ShowinTeaskbar" was set to False - my bad ]

2) How can I find multiple occurances of a single file on a specified drive (eg how many times you have mIRC installed). Atm I can only find one occurance per drive.

3) How can I store an emence amount of data easily, and retrive info from it quickly (I'm talking like 16,000 entires, each with 10 sub-entires), I was using an array like so:

Type hlserver
address As String * 32
name As String * 256
map As String * 64
dir As String * 32
desc As String * 70
active As Integer
max As Integer
type As Integer
os As Integer
pass As Integer
End Type
Global hlservers() As hlserver

but that only works for 800 or so entires before running out of memory (thus crashing my program).
Next I tried putting is all in a combobox, but that was a very slow way of doing it, but it worked.
Then I read a post on here that talked about collections, what are these, and could they help me?
Also a friend who's learning C++ said he could store the info in a dll, it that possible??


If you know an answer to even one of my problems, please post a reply, I need your help!
