For each line as string in alllines
Dim item As New ListViewItem
item.Text = line

Custom Control Property Load Order
Aug 9, 2010I've created a custom control in VB.NET on .Net 3.5, in VS2008, which contains a load of custom properties, including RSS feed address, proxy address and proxy port.This control is an RSS ticker, which works really nicely, but doesn't initially run at all, and from stepping through my code, this is because none of my properties are being passed data from the containing form, until after the control has been initialised, and the code behind the control has run. The code (relevant bits) looks as follows:[code]

Index Was Out Of Bounds - For Loops And Arrays
Nov 23, 2009I'm trying to create two arrays filled with a set of strings from two tables in a database and then compare them. For example:
array1[0]="1101" and
array2[0]="0110"
If both respective characters equals 1 then perform an action. But when I run this code I receive the error: Index was outside the bounds of the array. System.IndexOutOfRangeException.
For some reason I believe the problem area is with the following two statements:
comparestringa = userintarray(x) and
comparestringb = eventintarray(x)
When I comment them out, the error doesn't show.
myconnect = New SqlConnection("xxxx")
Dim Table1 As New SqlCommand("SELECT * FROM Table1", myconnect)
Dim Table2 As New SqlCommand("SELECT * FROM Table2", myconnect)
Dim array1 As New ArrayList
Dim array2 As New ArrayList

View 5 RepliesVS 2010 Make A Property Page?
Dec 30, 2011I'm in the process of making a usercontrol and i've run into the problem of how to make a property page. Obviously this makes setting up you control nicer and more importantly to my program makes loading the form faster (setting the properties in the load event vs property page). I was trying to find something to start on but i didn't find a propety page in the "New Item" menu or even something like the "Property Pages" property of a usercontrol in vb6 where i've done this before. How can i make the equivalent of the vb6 property page in vb.net? Maybe with a form or a dialog?

VS 2010 User Control Property - Group Attributes?
Apr 2, 2010this questions has be answered partially, but I can't find any full tutorial for this problem.I created my own user control (an advanced list with columns). Each column has different attributes like width, colour and text.I want to able to add this user control onto a form and select/edit the different attributes of each column. Hence, for each column in my user control (these columns are created beforehand, no columns can be added or removed from it) there should be a property in the property-menu. Each of these column-properties should be expanded (like the normal size-property in most default vb-controls that can be expanded with the little plus to show the width and height individually.What i mean by this, is: In the property-menu there should be attributes like Column1, Column2, Column3. Each of these attributes should be expanded to show the attributes like width or colour.
Currently I have different properties for different values of the same column, like Column1Wodth, Column1Colour, etc, but I want to group this under one value Column1.I think this is quite an easy solution, but forgive me, I spent more than 4 hours on google, but couldn't find a proper solution.
