Restricting Form movement **

Is there any way in which you can make a windows form 'stick' in a particular position? Eg. when you left click the control bar and try to drag it, it does not move. One other question: Lets say you have an mdiParent form and mdiChild. Even with autoscroll=false, if you drag the child slightly out of the parent area, the parent will display the scrollbars. How do you avoid this? (ie. "lock" the child inside the mdiParent so that it can never be displayed outside). cheers
