Resize dynamically the size of the CFormView

Hello,

I have a view which derives directly from the CFormView and then I
display a child dialog on it at runtime.
Visual Studio creates automatically resource entry for my view class.

The dialog can be resied dynamically by the user by pressing the
button and I would like the view to always fit the size of the dialog.
At the moment when I press a button and the dialog dimensions change I
cannot resize the view and a scrollbar is created, which looks really
ugly.

Could someone help me with this problem? How can I automatically
resize the view so that it always fits the dialog window?

Everything is happening in the MDI world.

Thanks for help,

Pshemek

Call ResizeParentToFit from within the View.

Scratch that:
Do this instead:

CRect Rect;

GetWindowRect(&Rect);

SetWindowPos(NULL,0,0,Rect.Width()+50,Rect.Height()+50,SWP_NOMOVE|SWP_NOZORDER);

GetParentFrame()->GetWindowRect(&Rect);

GetParentFrame()->SetWindowPos(NULL,0,0,Rect.Width()+50,Rect.Height()+50,SWP_NOMOVE|SWP_NOZORDER);

Should I include this in OnInitialUpdate() or perhaps in OnInitDialog
in the child dialog??

Well,

This does not work, the frame is much bigger than the dialog itself.
Any other ideas?

Thanks for help

There's something incredibly suspect about any computation that has this many casts. I've
done resized CFormViews without ever writing anything this convoluted.

It also has long-term risks in that it assumes that the active view is a CFormView (and
when the client says, "By the way, we want a graphical view as well", your code had better
keep working, and the above code will fail horribly).

In some cases, I want the view to resize and I want the controls to dynamically resize to
match; in other cases, I really want the scrollbars. But in neither case did I end up
writing something that involved either GetActiveView() or a cast. I consider the
combination of GetActiveView and explicit casting to be extremely hazardous. I rarely
even consider GetActiveView to be even meaningful.

You can check out a number of examples on my MVP Tips site that have dynamically resized
CFormViews.
