class CMyClass<br />

public:<br />
  void MyFn (void);<br />
  static void MyStaticFn (CMyClass *);<br />

<br />
typedef void(* FnPtr)(CMyClass*);  // C style fn pointer<br />

1. Use ShellExecute()

   ShellExecute(m_hWnd, "print", "MyFile.txt", NULL, NULL, SW_HIDE);
   

   This will execute the program associated with the .txt extension and tell it to print the file.




2. Use system()

   system("copy "MyFile.txt" lpt1:");
   

   This will send the file to the printer using the DOS copy command. Note that the last (partial) page will probably not be printed, unless you send a formfeed.




3. Use MFC's doc/view printing architecture. See the Printing section here on CP for more details.

ShellExecute(m_hWnd, "open", "help.pdf", NULL, NULL, SW_SHOW);

void CMyEdit::Insert(LPCTSTR lpszText)
{
    SetSel(0, 0);
    ReplaceSel(lpszText);
}

CMyEdit m_edit;
.
.
.
for (int n = 0; n < 100; n++)
{
    CString str;
    str.Format("This is line %d\r\n", n);
    m_edit.Insert(str);
}
