<body class='hmmessage'>Hi Everyone,<BR>
<BR>
It turns out my previous patch was not right to solve the problem.<BR>
<BR>
After writing a win32 application for debuging the impact of SetClassLongW, <BR>
I found out that something is abnormal in windows.<BR>
<BR>
After a built-in class (which has procA and procW) is subclassed by<BR>
<BR>SetClassLong(Ptr)W(hWnd, GCL_WNDPROC, newProcW);<BR>
<BR>
If you create a window of the same built-in class (such as Edit) using CreateWindow(Ex)A,<BR>
the created window got it's wnd.procA = class.<FONT face="">newProcW. </FONT>The created window is Ansi.<BR>
<BR>
That is right, the newProcW is going to receive Ansi message - [ABNORMAL].<BR>
I have captured the debug screen, here is the screenshot<BR>

<BR>
Where in Wine, created window is Unicode, with wnd.procW = class.newProcW.<BR>
newProcW will only receive Unicode message.<BR>
<BR>
That is the difference between Window and Wine regarding to subclass built-in control.<BR>
This observation explains exactly what I have seen in my App.<BR>
<BR>
With this knowledge it's now easy to create the patch.<BR>
