I would suggest that instead of accessing the page to set information, have
the page ask for the information when it is getting activated.
Or you can simply tell the page, and the page stores the info in a buffer
somewhere, and if the controls are created (have a valid m_hWnd) then sets
the data in the controls, otherwise it will wait and set the data in the
controls when OnInitDialog gets called.

By the way never access the control of a dialog box from outside, it's just
to dangerous, as you have found out.
Have accessor method, SetxxxText, GetxxxxText.....

My app is constructed this way: App creates primary dialog, dialog creates
PropSheet, PropSheet creates 4 PropPages.

One of the property pages (#3 of 0-3) displays data acquired from the
network. The network access and page population is done from the primary
dialog. The pages only send messages back to the primary dialog. The
primary
dialog does nearly all the work.

If I select the tab of page #3 so that the property page is showing (or
has
at least been shown once) the population of the edit boxes with the
network
values works. This is done via a pPSheet->pPage3->CEditCtl.member_function
implementation.

However, if the property page has not been active, and therefore
OnInitDialog did not run, I get an assertion error when accessing the
CEdit
ctls. I tried SetActivePage(3); but this doesn't really make OnInitDialog
run
which seems to be what is needed to fix the problem.

What is the correct way to deal with this?
