隐藏窗口的任务栏按钮后窗口最小化的问题，有源代码。

[臭油松]

BOOL CMainFrame::PreCreateWindow(CREATESTRUCT& cs)
{
...
if (!::IsWindow(m_wndInvisible.m_hWnd))
{
LPCTSTR pstrOwnerClass = AfxRegisterWndClass(0);
if (!m_wndInvisible.CreateEx(0, pstrOwnerClass, _T(""), WS_POPUP,
CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT,
NULL, 0))
return FALSE;
}
cs.hwndParent = m_wndInvisible.m_hWnd;
...
}

问题：我运行后任务栏的按钮的确隐藏了，可是当我最小化时，窗口却跑到了屏幕的左下角，就像在MDI窗口内子窗口的最小化似的。即便是我用下面消息拦截也不行：

void CMainFrame::OnSysCommand(UINT nID,LPARAM lParam)
{
if (nID==SC_MINIMIZE)
{
//AfxMessageBox("ZUIXIAOHUA");
ShowWindow(SW_HIDE);
}
CFrameWnd::OnSysCommand(nID,lParam);
}

So where do you want to window to appear.
It seems that your window couldn't reside in the taskbar!

void CMainFrame::OnSysCommand(UINT nID,LPARAM lParam)
{
if (nID==SC_MINIMIZE)
{
//AfxMessageBox("ZUIXIAOHUA");
ShowWindow(SW_HIDE);
return;
}
CFrameWnd::OnSysCommand(nID,lParam);
}

UP;
要不更绝一点：SetWindowPos();设置cx = cy = 0; :)
