If you'd like to prevent a form or the access-window from being resized below a certain level, the resize-event might be what you're using. However, I bet you're encountering a lot of flickering when doing so, right? Well, the flickering is caused due to the fact that - when this event triggers - the resize-action will already have taken place - leaving you one step behind events ...
Using subclassing, this sample database hooks into the windows-messaging-system which will be fired before the new size is passed to the form's resize-event.
Also in this sample: a small module which will help retrieve twips-per-pixel ratios.
This is one of the older entries that can also be found on the original Access-site.
