Bug ID: 57746
           Summary: BeckyInternetMail/VirtualListView: The ListView of the
                    email list isn't redrawn while receiving email.
           Product: Wine
           Version: 10.0
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: comctl32
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

Screen recordings of the original operation (win8.1) and the incorrect
operation (wine). Please check the attached mp4.

Bug Description:

Win8.1 (correct):
- Click on the “Inbox” button.
- Press the “Receive Mail” button
- Each time an email is received, the email is added to the email list.

Wine (wrong):
- Click on the inbox
- Press the “Receive Mail” button
- Mail is received, but the ListView of the mail list is not updated at all.
After switching to another location, such as the outbox, click the inbox again,
and the new mail will appear in the ListView.

I used Spy++ to investigate Becky on Win8_1. I found the LVM_SETITEMCOUNT
message in the ListView of the Mail List screen. Maybe the Virtual List View is
not redrawing properly.

I have found the cause/solution of the bug.

Sending LVM_FINDITEMA (Ascii version. not W!) to VirtualListview by SendMessage
will send LVN_ODFINDITEMW (Wide version. not A!) to the listview/parent window.
Correctly, LVN_ODFINDITEMA (Ascii version. not W!) should be sent.
LVN_ODFINDITEMW will be sent for both LVM_FINDITEMA and LVM_FINDITEMW.
Therefore, if your program has only LVN_ODFINDITEMA handler, LVN_ODFINDITEMW
will be processed by::DefWindowProc and always returns 0.
Therefore, LVM_FINDITEMA/ListView_FindItemA will not work at all. It always
returns 0.
LVN_ODFINDITEMW ! = LVN_ODFINDITEMA

If LVM_FINDITEMA, please send LVN_ODFINDITEMA

I also found one other bug.
It probably won't work if you only have a handler for LVN_ODFINDITEMA(Ascii
only).
