How do I return control to dialog during processing?

[Rob]

Hi,

I've developed a basic dialog program using the MFC foundation wizard.

Upon pushing one of the buttons, a time consuming processing is invoked,
during which the user cannot access the 'Cancel' pushbutton, nor can the
processing in question update any fields in the dialog box. It can updated
the progress bar however.

In order to release the window during this time consuming processing to
allow the user to cancel the processing, do I have to create a separate
thread? Will OnIdol() be a feasible option? Are there any simpler options
that I'm overlooking?

Thanks
Rob

A thread is probably best but there might be other solutions, this
however is off-topic here since it's not a C++ language concern. For
