I'm not sure where to begin. The secondary threads should not communicate with the UI components owned by the primary thread. If the secondary threads need to update a UI component, they should do so by posting a message to the primary thread.

how will i call the objects (from the dialog which i have created) inside a thread declared in created dialog ?

in the main dialog i have used -- CMainDlg *dialog=(CMainDlg*)AfxGetApp()->GetMainWnd();

and for getting an object of listbox (dialog->m_list where m_list is member variable of list box in maindialog) in the thread which i have been using.

Call RegisterWindowMessage() to define a new window message (that is guaranteed to be unique throughout the system). In the secondary thread, post that message. In the primary thread, respond to that message like:

ON_REGISTERED_MESSAGE(USER_WINDOWS_MESSAGE, OnMyMessage);
...
LRESULT CMyDialog::OnMyMessage(WPARAM, LPARAM lParam)
{
    // do something like update a listbox or a progress control
    return 0;
}

"Best" meaning "New and improved"? Or the "Best" because it has a 30 day money back guarantee?

"Lean and mean" code as in development/maintenance overhead or runtime performance? Never mind I have lost interest now since it has taken you at a minimum three posts to explain your request.

Really you consider your original post to be "specific"? In that case you might want to consider this[^].

modal like a modal dialog? If so, that means the user
must dismiss the window before (s)he can do anything else.

To do that,

1) disable other windows
2) create the window
3) run a message loop until the modal window is closed/dismissed
4) enable other windows
5) destroy the modal window

I would swap (4) with (5), but maybe I'm wrong.

Either way...whichever way is most pleasing to the user.

All the repaints resulting in the destruction and re-enabling
will determine that I suppose Smile | :)

Thank you so much Mark.
You're answer is prudent and accurate.

I must say that I have begun to doubt my coherency during this thread.
There's an obvious correlation between one's willingness to help and his understanding of the question.

Hi guys
¿Do you know a way to show a long text (CString) in a CStatic justified or left aligned?
Thanks in forwarding.

And what is the value of the second argument?
