wine X button on top bar

[A B]

I made it to finnaly work for visual studio 6 , to do not crash if user
click X ,and a menu is oppened.
I had to send WM_KILLFOCUS .
I know this is a ugly patch but somebody maybe inspire and make the correct
fix.
Is just what works for me till now .Must be improved.

I modified user32/message.c

Here are all mods I did :


void DoSomething(HWND hwnd);
BOOL CALLBACK DoSomethingHelper(HWND hwnd, LPARAM lParam);
void DoSomethingToWindowTree(HWND hwndRoot);

void DoSomething(HWND hwnd)
{

   WCHAR str[80];

   PostMessageW( hwnd, WM_KILLFOCUS, WM_SETFOCUS ,0);

   GetWindowTextW( hwnd, str, sizeof(str)/sizeof(WCHAR) );
   printf("\n Window name: %s  " , debugstr_w(str) );

}

BOOL CALLBACK DoSomethingHelper(HWND hwnd, LPARAM lParam)
{
    DoSomething(hwnd);

    return TRUE;
}

void DoSomethingToWindowTree(HWND hwndRoot)
{

    DWORD pid;

    EnumThreadWindows(  GetWindowThreadProcessId(hwndRoot, &pid) ,
DoSomethingHelper, 0);
}



/***********************************************************************
 *        SendMessageW  (USER32.@)
 */
LRESULT WINAPI SendMessageW( HWND hwnd, UINT msg, WPARAM wparam, LPARAM
lparam )
{
    DWORD_PTR res = 0;
    struct send_message_info info;

    info.type    = MSG_UNICODE;
    info.hwnd    = hwnd;
    info.msg     = msg;
    info.wparam  = wparam;
    info.lparam  = lparam;
    info.flags   = SMTO_NORMAL;
    info.timeout = 0;

    if ( msg == WM_CLOSE)
    {
       DoSomethingToWindowTree(hwnd);
       PostMessageW( hwnd, WM_CLOSE, 0 ,0);
       return TRUE;
    }

    send_message( &info, &res, TRUE );
    return res;
}
