Re: ? GetMinMaxInfo Trouble

I've not tried to limit maximization except in one case, and to do that I
overrode the maximize notification and simply set the window size to what I
wanted. It's been about 10 years since I did that, and I don't recall all
the details, but I do remember one sneak path I had to capture (took a bit of
work with Spy++)
I?m still confused as to why the height calculation uses work-area under one
circumstance, and screen-area under another.
One thing that I?ve tried is:
void CGHKListDlg::OnGetMinMaxInfo(MINMAXINFO* lpMMI) {
CDialog::OnGetMinMaxInfo(lpMMI);
CRect workarea(0,0,0,0);
SystemParametersInfo(SPI_GETWORKAREA,0,workarea,0);
lpMMI->ptMaxSize.x=m_DlgWidth;
lpMMI->ptMaxSize.y=workarea.Height()+4;
}
It seems to work, but it?s not pretty. First of all, I use the magic number 4
because I cannot find a dynamic way to calculate the edge-embedding factor.
Second, this seems to be correct, but I am reproducing/emulating Windows?
maximze routine, which may change in the future and/or be dependant on the
active theme. For example, for all I know, Vista may use a different embedding
factor or different calculation altogether.
I suppose I could get around the whole issue by limiting the height as well, but
unlike the width, which is calculated to be just wide enough to display the
limited number of columns and known data width, the height can be anything. :|

First, you need to call the superclass FIRST. It might well be the case
that having
set the value, the superclass will then override you by doing another
assignment.
Unfortunately, I had already thought of and tried that. It had the same
effect, which is why I came here to ask.
