A class based on CWnd is my main window. From this, it is possible, by clicking on various parts, to start MFC dialogs. At this time, I want the MFC dialog to be visible, the main window to be invisible, and the icon from my main window to remain in the task bar. I cannot seem to accomplish these all at once.
Typical code for starting the MFC dialog is
CMyMFCDialog *pDlg=new CMyMFCDialog;
pDlg->DoModal();
delete pDlg;
If I precede this with ShowWindow(SW_HIDE) in the main window class, the main window vanishes, and so does the task bar icon.
If instead I use ShowWindow(SW_MINIMIZE), the task bar icon remains, as wanted, but the modal dialog is not visible.
I can't use pDlg->ShowWindow in the main window class, because the dialog window has not yet been created.
Even if I put ShowWindow(SW_SHOW) (or SW_NORMAL) in the OnInitDlg handler in CMyMFCDialog, the dialog remains invisible. It can only be made visible by toggling the task bar icon.
