SUMMARY
=======

The default behavior of the ListView control, when in Report View, is the
ability to select only the item on the far left of the list. If you try to
select any of the sub-items, nothing happens. Only the first item is available
to be selected.

You can avoid this limitation by adding a ListView extended style,
LVS_EX_FULLROWSELECT, to the current ListView style. With this extended style
you can select any sub-item and the entire row will be selected.

Step-by-Step Example
--------------------

1. Start a new Standard EXE project. Form1 is created by default.

2. Select Components on the Project menu. Click the check box next to "Microsoft
   Windows Common Controls 5.0," and then click OK.

3. Add a ListView control (ListView1) to Form1.

4. Add a CommandButton (Command1) to Form1.

5. Add the following code to the Form module:

         Private Declare Function SendMessage Lib "user32" Alias _
           "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal _
           wParam As Long, lParam As Any) As Long

         Const LVS_EX_FULLROWSELECT = &H20
         Const LVM_FIRST = &H1000
         Const LVM_GETEXTENDEDLISTVIEWSTYLE = LVM_FIRST + &H37
         Const LVM_SETEXTENDEDLISTVIEWSTYLE = LVM_FIRST + &H36

         Private Sub Command1_Click()
           Dim lStyle As Long
           lStyle = SendMessage(ListView1.hwnd, _
              LVM_GETEXTENDEDLISTVIEWSTYLE, 0, 0)
           lStyle = lStyle Or LVS_EX_FULLROWSELECT
           Call SendMessage(ListView1.hwnd, LVM_SETEXTENDEDLISTVIEWSTYLE, _
              0, ByVal lStyle)
         End Sub

         Private Sub Form_Load()
           'Add two Column Headers to the ListView control
           Set clmAdd = ListView1.ColumnHeaders.Add(Text:="Name")
           Set clmAdd = ListView1.ColumnHeaders.Add(Text:="Date")

           'Set the view property of the Listview control to Report view
           ListView1.View = lvwReport

           'Add data to the ListView control
           Set itmAdd = ListView1.ListItems.Add(Text:="Joe")
           itmAdd.SubItems(1) = "05/07/97"

           Set itmAdd = ListView1.ListItems.Add(Text:="Sally")
           itmAdd.SubItems(1) = "04/08/97"

           Set itmAdd = ListView1.ListItems.Add(Text:="Bill")
           itmAdd.SubItems(1) = "05/29/97"

           Set itmAdd = ListView1.ListItems.Add(Text:="Fred")
           itmAdd.SubItems(1) = "05/17/97"

           Set itmAdd = ListView1.ListItems.Add(Text:="Anne")
           itmAdd.SubItems(1) = "04/01/97"
         End Sub

6. Press the F5 key to start the program. Click one of the entries in the Date
   column and observe that nothing occurs. Click on an entry in the Name column
   and note that only the name is highlighted.

7. Click the command button and then click on entries in each column. Note that
   an entire row can now be selected by clicking an item in either column.
