Answer 1

 void CApp2Dlg::OnButton1() 
{
    // TODO: Add your control notification handler code here

    char buffer[201];
    int n = m_edit1.GetLine(0, buffer, 100);
    *(buffer + n) = '\0';
    CFileDialog saveFile(FALSE, ".txt", buffer, OFN_CREATEPROMPT | OFN_PATHMUSTEXIST , "Text Files|*.txt|All files (*.*)|*.*||");
    saveFile.DoModal();
}
