Navigating through CListCtrl's rows with the arrow and tab keys

I needed to be able to edit some fields from a database, and wanted to have a label, the field name, followed by an edit box that the user could enter the field data in. The only problem was that there could be anywhere from 1 to 50 fields. So I used a CListCtrl with two columns to represent the field name and the field value. There are many articles here that show how to edit subitems, but I only needed to be able to edit one item on each row, so I just rearranged the columns to have the editable item be the second cloumn. The following code is all that is necessary to rearrange the columns.

int aiCol[2] = { 1, 0 };
m_List.SetColumnOrderArray (2, aiCol);

Inside a message handler for the LVN_BEGINLABELEDIT message, you need to add the following code:

HWND hWnd = (HWND)SendMessage (LVM_GETEDITCONTROL);
ASSERT (hWnd != NULL);
if (m_Edit.m_hWnd != 0)
	m_Edit.DestroyWindow ();
VERIFY (m_Edit.SubclassWindow (hWnd));

Inside a message handler for the LVN_ENDLABELEDIT message, you need to add the following code:

if (m_Edit.m_hWnd)
	VERIFY (m_Edit.UnsubclassWindow () != NULL);
