1. Add a public method to your first dialog box, that appends a letter to the edit control. For example:

   void CFirstDlg::TypeLetter
     (CString theLetter)
   {
     CString strText;
     CEdit* pEditBox = GetDlgItem (IDC_EDIT_BOX)
     pEditBox->GetWindowText (strText);
     strText += theLetter;
     pEditBox->SetWindowText (strText);    <code>// append typed letter</code>
     int nLen = strText.GetLength();
     pEditBox->SetSel (nLen, nLen, TRUE);  <code>// position cursor at end</code>
   }
   

2. When you create your second dialog, pass it a pointer to the first dialog box. In the button handlers of your second dialog box, "send" the typed keystroke to the first dialog box. For example:
   

   void CSecondDlg::TypeD()
   {
     m_pFirstDlg->TypeLetter ("D");
   }
   

CFirst *m_First=(CFirst*)GetParent();
<code>m_First->m_str;</code> or  <code>m_First->yourcontrol</code>
