If I understand you correctly, all you'd need to do is set the form's
size property[
^]. The size consists of the height and width. You can set them individually if you want to.
If you have a panel that you want to show or hide, you can do that too. You may need to move things around a bit on your form so you'll want to look into the anchor property of the controls and the
location property[
^] of controls that you have on your form to see how to move them around.
Also, the
anchor property[
^] is useful when you want controls to stretch with the form when it is resized.
Hope this helps.
