resizing dialog box to parent client area

[b_girl]

I know I asked about this a few weeks ago, and someone was kind enough to supply me with some (still untested) code:

CMyDialog::doMaximize()
{
CRect rect;
GetParent()->GetClientRect(&rect);
ClientToScreen(&rect);
MoveWindow(&rect);
}

I was wondering what message had to be sent in order for this bit of code to get executed? The only ones I could think of using were WM_SIZE or WM_MOVE but I really don't think they're what I want. I tried handling the WM_SIZE, but it didn't do exactly what I'd like it to have done.

Have you tried putting it in OnInitDialog?

By putting it in OnInitDialog, wouldn't that start the dialog out maximized? I want it to maximize like that only when the user clicks on the maximize button up in the top corner of the dialog, otherwise I want it to remain the size it was when it opened initially (and also be able to be minimized)
