The types of controls that are displayed depend on the features that you specify during the Form Wizard question-and-answer phase. The types of controls are listed in the following table.
| Feature Type | Generated Control |
|---|---|
| Boolean | Check box |
| Binary | Picture |
| Class | Combo box |
| Collection-class | List box |
| Other primitive types | Text box |
The following points apply to the creation and positioning of controls on your form.
Controls are created in the center of the form, starting at the top and then stacked down the form with a small gap between each control.
If the number of created controls does not fit into the visible area of the form, a vertical scroll bar is added to the form.
If you specify a large number of features to be displayed on your form, you may have to use the Painter to relocate the controls for a more aesthetic layout.
You can specify any number of controls on your form. The limit is controlled by available memory, but is far more than any practical limit.
Controls are created as read-only when the associated feature is:
A method
A read-only or protected property
Type Binary, or a collection
A property at the Auto end of an explicit inverse reference
