Re: SW_SHOW & SW_HIDE

Hi Guru,

I'm using SDI application

I got two dialogs in resource :
      IDD_MYDIALOG1 (class CMyDlg1) and
      IDD_MYDIALOG2 (class CMyDlg2)

After click the menu ID_TESTDIALOG, it loads IDD_MYDIALOG1, and hide
the Main Frame window, and then it run some timer, and after it meet
some
condition, it will load IDD_MYDIALOG2 and hide both IDD_MYDIALOG1 &
Main Frame window.

Close/destroy IDD_MYDIALOG2 or click save button (OnBtnSave() ) in
IDD_MYDIALOG2 will return to IDD_MYDIALOG1 (while Main frame window
still hide)
Close/destroy IDD_MYDIALOG1 will return to Main Frame Window

In Timer function below, what should I code to hide IDD_MYDIALOG1/Main
frame window and load IDD_MYDIALOG2 ?
In OnBtnSave(), how to return to IDD_MYDIALOG1 with main frame window
hide ?

void CMainApp::OnDialog1Action()
{
CMyDlg1 Dlg1;
this->GetMainWnd()->ShowWindow(SW_HIDE);

Dlg1.DoModal();

this->GetMainWnd()->ShowWindow(SW_SHOW);

}

void CMyDlg1 ::OnTimer(UINT nIDEvent)
{
    ....
    status = MY_OWN_API_FUNCTION(....)
    if (status = 0)
    {
// how can I hide this IDD_MYDIALOG1 and also hide MainFrameWindow,
and load IDD_MYDIALOG2 in easiest way ?
    }

Many thanks.
