1. Please update your profile so that it contains a non-empty name. While we love to help, we like to know who we're helping. Thanks.
   
   
2. See this[^] link. Also see this[^] link when you're ready dive into more complex topics.

1. Add 2 buttons (IDC_HOST_CHANGE and IDC_LOGON_CHANGE) to CNewDlg and make them invisible.
   
   
2. Write a handler for each - the one for IDC_HOST_CHANGE should call HostChange() and the one for IDC_LOGON_CHANGE should call LogonChange().
   
   
3. HostChange() and LogonChange() should get a pointer to an (perhaps the) instance of LinkPtr via a singleton access method exposed by your app class.
   
   
4. Your static callbacks should post the appropriate message to your app's AfxGetMainWnd(). No casting to CNewDlg is required. For example:

   AfxGetMainWnd()->PostMessage (WM_COMMAND, IDC_HOST_CHANGE);
   

#define WM_MY_MESSAGE (WM_APP + 1)

afx_msg LRESULT OnMyMessage(WPARAM wParam,LPARAM lParam);

BEGIN_MESSAGE_MAP(...)
// ...
ON_MESSAGE(WM_MY_MESSAGE,OnMyMessage)
// ...
END_MESSAGE_MAP()

LRESULT MyDialogClass::OnMyMessage(WPARAM wParam,LPARAM lParam)
{
  // ...
}

my_dialog->SendMessage(WM_MY_MESSAGE,
                       (WPARAM)first_parameter,
                       (LPARAM)second_parameter);

System::Void Form1_Paint(System::Object^  sender, System::Windows::Forms::PaintEventArgs^  e) <br />
{<br />
<br />
     System::Drawing::Drawing2D::GraphicsPath ^shape =<br />
     gcnew System::Drawing::Drawing2D::GraphicsPath();<br />
<br />
     shape->AddEllipse(0, 0, this->Width, this->Height);<br />
<br />
     this->Region = gcnew System::Drawing::Region(shape);<br />
<br />
}
