Testing the CEditStream.

1. Use the MFC AppWizard(exe) to create a dialog based project named "testCEditOutputStream".



2. Edit the resource of the main dialog window as shown.




3. Set properties for the dialog components.

   Component	Property name	Property value
   Large editor box	ID	IDC_MAINEDITORBOX
   Large editor box	Styles->Multiline.	Checked
   Large editor box	Styles->Want return	Checked
   Large editor box	Styles->Vertical Scroll	Checked
   Small editor box in the position section	ID	IDC_POSITIONEDITORBOX
   Small editor box in the text section	ID	IDC_TEXTEDITORBOX
   Small editor box in the text section	Styles->Multiline	Checked
   Small editor box in the text section	Styles->Want return	Checked
   	Styles->Vertical Scroll	Checked
   "Get" button	ID	IDC_GET
   "Set" button	ID	IDC_SET
   "Get max" button	ID	IDC_GETMAX
   "Move by" button	ID	IDC_MOVEBY
   "Set at end" button	ID	IDC_SETATEND
   "Set at start" button	ID	IDC_SETATSTART
   "Insert" button	ID	IDC_INSERT



4. Assign variables to the dialog components.

   ID	Type	Name
   IDC_MAINEDITORBOX	CEdit	m_edit
   IDC_POSITIONEDITORBOX	int	m_position
   IDC_TEXTEDITORBOX	CString	m_text



5. Setup message handlers.
   1. To prevent dialog box from closing when the user presses key anywhere in the dialog change the ID property of the OK button to ID_OKBUTTON. Add a new message handler to the "BNCLICKED" event:
      void CTestCEditOutputStreamDlg::OnOkbutton() { if (CanExit()) CDialog::OnOK(); }
      and make the function OnOK() empty:
      void CTestCEditOutputStreamDlg::OnOK() {}
   2. Assign the following message handlers to the BNCLICKED event of the control buttons

      ID	Handler
      IDC_GET	CTestCEditOutputStreamDlg::OnGet
      IDC_SET	CTestCEditOutputStreamDlg::OnSet
      IDC_GETMAX	CTestCEditOutputStreamDlg::OnGetmax
      IDC_MOVEBY	CTestCEditOutputStreamDlg::OnMoveby
      IDC_SETATEND	CTestCEditOutputStreamDlg::OnSetatend
      IDC_SETATSTART	CTestCEditOutputStreamDlg::OnSetatstart
      IDC_INSERT	CTestCEditOutputStreamDlg::OnInsert



6. Attach the following files to the project:
   OutputStream.h
   EditorOutputStream.h
   CEditOutputStream.h
   OutputStream.cpp
   CEditOutputStream.cpp
   


7. Build and run the application.
