[Bug 38759] New: WM_USER (and +1, +2) are being sent to application windows

            Bug ID: 38759
           Summary: WM_USER (and +1, +2) are being sent to application
                    windows
           Product: Wine
           Version: 1.7.38
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: wine-bugs(a)winehq.org

My programs use WM_USER, WM_USER+1 and WM_USER+2 for various functions, but
they seem to be sent these messages by WINE when the mouse moves around the
window involved, possibly during repainting.  This doesn't happen in Windows. 
I've changed my offsets of 0x0400 to add 0x0280 (I now start acting on messages
at 0x0680 instead) and it's fixed - but it's clearly a bug in WINE.

Hi, Jason.

Could you share a minimal test case application source that shows this problem?

Hi Nikolay,

I'm glad you asked, as I realised I'm running Win-MONO on WINE for this
software, so I should test that on Windows with MONO instead of making
assumptions about WINE...  It also fails there too, so it's a MONO bug, not a
WINE bug.

Anyway, this is a standard C# winforms project that shows the issue when the
mouse passes over the window.

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace TestWine
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        public const int WM_USER = 0x0400;

        protected override void WndProc(ref Message m)
        {
            switch (m.Msg)
            {
                case WM_USER:
                case WM_USER + 1:
                case WM_USER + 2:
                    MessageBox.Show("Ouch! Msg=" + m.Msg);
                    break;

                default:
                    break;
            }
            base.WndProc(ref m);
        }
    }
}

Sorry for the bogus bug report,
Jason.

I see, so it's something it mono probably that makes use of WM_USER messages.
Thanks for testing.
