Do not under any circumstances put this in the PreTranslateMessage handler. This is
wrong, and a misuse of PreTranslateMessage. Just add to the message map
ON_MESSAGE(OECM_MESSAGE, OnOecmMessage)
or
ON_REGISTERED_MESSAGE(OECM_MESSAGE, OnOecnMessage)
where you had defined
LRESULT ViewConnections::OnOecmMessage(WPARAM, LPARAM)
{
...format stuff here
return 0;
}
Note that this code forces you to read the current time EVERY TIME A MESSAGE IS RECEIVED,
which is completely silly.
The UpdateData is pointless and serves absolutely no useful purpose. There is nothing
here that sets any state that UpdateData is concerned with or manipulates. Get rid of it.
And what, exactly, is a "print statement"?

Another noob question...
I need to pass a message from a main frame window to one of its
children...the child is created with
dlg = new Window();
dlg->Create(IDD_TABHOLDER,this);
dlg->ShowWindow(SW_SHOW);
within the main frame. Then the message is sent:
SendMessageToDescendants(OECM_MESSAGE,0,0,true);
In the child dialog class, I do the following:
BOOL ViewConnections::PreTranslateMessage(MSG* pMsg)
{
// TODO: Add your specialized code here and/or call the base class
CString msg;
CTime theTime = CTime::GetCurrentTime(); //the current time
switch (pMsg->message)
{
case OECM_MESSAGE:
msg.Format("{%02d:%02d:%02d} SubSkillsNet Connection
Established",theTime.GetHour(),
theTime.GetMinute(),theTime.GetSecond());
listbox.AddString(msg);
UpdateData(false);
break;
default:
break;
}
return CDialog::PreTranslateMessage(pMsg);
}
But the child dialog never receives the message...this was confirmed
with a print statement inside the first case of the switch
statement....Any ideas here?
Thank you!
