Question

VC 中怎样使COMBO BOX和Edit Box 隐藏和显示?

loving525:
//这样写的，运行出错了……
void CSMMISView::OnInput()
{
// TODO: Add your command handler code here
CININPUT dlg;
GetDlgItem(IDC_INDEX)->ShowWindow(0);
dlg.DoModal();
}
BOOL CWnd::ShowWindow(int nCmdShow)
{
ASSERT(::IsWindow(m_hWnd));//到这句显示"Unhandled expexception ... AccessViolation"

if (m_pCtrlSite == NULL)
return ::ShowWindow(m_hWnd, nCmdShow);
else
return m_pCtrlSite->ShowWindow(nCmdShow);
}

隐藏
GetDlgItem(IDC_EDIT1)->ShowWindow(0);
GetDlgItem(IDC_COMBO1)->ShowWindow(0);
显示：
GetDlgItem(IDC_EDIT1)->ShowWindow(1);
GetDlgItem(IDC_COMBO1)->ShowWindow(1);
