When I set the Size property on the VB.NET form properties pane to a
size of 800, 1200 the 1200 always resets back to 1036? Why is that?

When I open a child form in the MDI parent the only way the MDI
displays scroll bars if if the child form is not maximized and is
moved over the edge of the MDI. Is there a way to turn those scroll
bars on when the child form is maximized?

The client rectangle of a window mustn't be bigger than the screen.

Why? If it is maximized, the whole child is visible. There's nothing to
scroll.

For me, this seems to be a bug. I don't know a way to turn the scrollbars
on.

If the MDI container is not maximized and the child is maximized, parts of
the child may not be visible (some of the controls). No scrollbars are
shown.

These are the scrollbars for the MDI child because some controls are not
visible, but IMO he was talking about the scrollbars of the MDI parent. The
latter is only shown whenever parts of the child are not visible. That's not
the case when it is maximized.

There is probably a Style bit you can set to accomplish this. But understand
this: even if the scroll bars are visible, there will be nothing to scroll.
If you are trying to scroll the child form, why don't you turn on the
scrollable propertys (AllowScroll, AutoScroll, AutoScrollMargin etc...) of
the child?

The MDI parent cares nothing about the child's controls, it only cares about
the child window- that is, if the child controls are hidden, the MDI parent
wont scroll the contents of the child.
