我的窗口嵌入到IE的工具栏中，但是无法用TAB键从其他窗口转入到我的窗口中，但可以从我的窗口转出。而且，很奇怪不能就受到退格键，鼠标的消息好像也不太正常。
当IE的工具栏有背景图案的时候，我的窗口有没有。
出了什么问题。
我可以提供我的程序（Delphi），能帮忙看看吗

我也连不上，go.163.com上的东西都是这样的，你应考虑放在其它地方，不知你问题解决了没有。

背景图片的问题解决了，是这样处理的(让父窗口为我去绘)
if (Message.Msg = WM_ERASEBKGND) then
begin
SetWindowOrgEx(frmBar.Canvas.Handle,frmBar.Left,frmBar.Top,nil);
SendMessage(ParentWnd,Message.Msg,frmBar.Canvas.Handle,Message.lParam);
end else
OldWndProc(Message);
　
但是键盘焦点的问题还是没有办法。请各位在看一看

我也连不上，go.163.com上的东西都是这样的，你应考虑放在其它地方，不知你问题解决了没有。

背景图片的问题解决了，是这样处理的(让父窗口为我去绘)
if (Message.Msg = WM_ERASEBKGND) then
begin
SetWindowOrgEx(frmBar.Canvas.Handle,frmBar.Left,frmBar.Top,nil);
SendMessage(ParentWnd,Message.Msg,frmBar.Canvas.Handle,Message.lParam);
end else
OldWndProc(Message);
　
但是键盘焦点的问题还是没有办法。请各位在看一看
