I got a very simple question regarding resizing listview columns. I have a form with a listview anchored to it (top, bottom, left, right). The form is resizable and the user will be able to resize the listview columns manually. However, I need the listview to resize its columns automatically when the form is resized (especially when its maximized).
But, I don't want all the columns to resize, only the ones I choose. For example, the listview will have 6 columns in total (0-5). When the user resizes or maximizes the window, I need only columns 2 and 4 (or columns 3 and 5 or columns 1 and 5) to resize. Now, I have come up with two pieces of code as listed below.
Code Part A: The following code only resizes one column. When the form is maximized, only the column ID provided will resize and fill the rest of the control. It works perfectly but I need to be able to resize multiple columns (as explained above):
Public Sub lvResizeSingleCol(ByVal resizeColumn As Integer, ByVal listViewName As ListView)
Dim w As Integer = 0
For column As Integer = 0 To listViewName.Columns.Count - 1
If column <> resizeColumn Then
w += listViewName.Columns(column).Width

I've just discovered though that any command, no matter how right the syntax, to a form from a different form doesn't work. The only command that does work is Form2.Show. Otherwise nothing happens. There are no errors whatsoever. All the items in each form are all set to public.

I have a media browser program I am building. I am trying to use drag/drop so a user can drag media tracks from one listview to another listview and then use the second list view as a playlist in windows media player com object. Reading at MSDN I have found out that there is no built in support for item re-ordering with the listview control. I have listview1 working correctly but when I try to reorder items in listview2, the dragged item ends up at the end of the list. So basically I need to get the item insertion index corrected. I have tried more than 10 times to get this code right.
Here is my code which includes a form with two listview's.
