Hi,
I need a way to update an Edit control control in MFC from a timer
callback function.
How can that be done as we cannot reference dialog box controls from
callbacks?

Even the following code gives me problems:

VOID CALLBACK TimerProc ( HWND hParent, UINT uMsg, UINT uEventID,
DWORD dwTimer )
{
  //Add the text
  CEdit *ptrtxtActivity;
  ptrtxtActivity = reinterpret_cast<CEdit
*>(GetDlgItem(hParent,txtboxActivity));
  ptrtxtActivity->SetWindowText(text);
}

Please let me know,

Thank you,
