how to find a window's SW_SHOW/SW_HIDE status

Question

I am trying to determine a window control\'s visibility that has been hidden or enabled with CWnd::ShowWindow(). (or ::ShowWindow(hWnd,nCmdShow))

I cannot simply use

Answer 1

If it is a multi-tab dialog and not a control, then override as

void MyClass::OnShowWindow(BOOL bShow, UINT nStatus)
{
    m_nCmdShow = bShow;
    CDialog::OnShowWindow(bShow, nStatus);
}

In BEGIN_MESSAGE_MAP, add ON_WM_SHOWWINDOW().

m_nCmdShow now has the status if the window is SW_SHOW or SW_HIDE.
