When controls are used, they must be placed in a form. Ok, there are a few exceptions such as the printer object or the screen object which are not considered part of any form, but are part of a VB program. Not to confuse the issue, but controls can also be placed inside of other controls. When this happens the parent control is known as a container. Likewise, forms are containers but are the highest level of container there is in a windows application.
Forms are always parents of controls, never the other way around.
There is one exception which I will not cover in these tutorials, and that is a special form called an MDI form. In this special case, an MDI form is always contained within a parent form. Each new Word document is contained in its own window, but is always framed within the larger window that is the Word application. Other than this brief mention, I will not cover MDI forms in these tutorials. Methods Now is a good time to bring up the 3 categories of information which may be used to describe any object, including forms.
