An animation control is a window that displays an Audio clip in AVI format. An AVI clip is a series of bitmap frames, like a movie. Animation controls can only play simple AVI clips, and they do not support sound. It is represented by the CAnimateCtrl class.
A button is an object that the user clicks to initiate an action. Button control is represented by CButton class.
A bitmap button displays a picture or a picture and text on its face. This is usually intended to make the button a little explicit. A bitmap button is created using the CBitmapButton class, which is derived from CButton.
A command button is an enhanced version of the regular button. It displays a green arrow icon on the left, followed by a caption in regular size. Under the main caption, it can display another smaller caption that serves as a hint to provide more information.
A static control displays a text string, box, rectangle, icon, cursor, bitmap, or enhanced metafile. It is represented by CStatic class. It can be used to label, box, or separateother controls. A static control normally takes no input and provides no output.
A list box displays a list of items, such as filenames, that the user can view and select. A List box is represented by CListBox class. In a single-selection list box, the user can select only one item. In a multiple-selection list box, a range of items can be selected. When the user selects an item, it is highlighted and the list box sends a notification message to the parent window.
A combo box consists of a list box combined with either a static control or edit control. it is represented by CComboBox class. The list-box portion of the control may be displayed at all times or may only drop down when the user selects the drop-down arrow next to the control.
A radio button is a control that appears as a dot surrounded by a round box. In reality, a radio button is accompanied by one or more other radio buttons that appear and behave as a group.
A checkbox is a Windows control that allows the user to set or change the value of an item as true or false.
An Image List is a collection of same-sized images, each of which can be referred to by its zero-based index. Image lists are used to efficiently manage large sets of icons or bitmaps. Image lists are represented by CImageList class.
An Edit Box is a rectangular child window in which the user can enter text. It is represented by CEdit class.
A Rich Edit Control is a window in which the user can enter and edit text. The text can be assigned character and paragraph formatting, and can include embedded OLE objects. It is represented by CRichEditCtrl class.

A timer is a non-spatial object that uses recurring lapses of time from a computer or fromyour application. To work, every lapse of period, the control sends a message to the operating system. Unlike most other controls, the MFC timer has neither a button to represent it nor a class. To create a timer, you simply call the CWnd::SetTimer() method. This function call creates a timer for your application. Like the other controls, a timer uses an identifier.
|20||Date & Time Picker
The date and time picker control (CDateTimeCtrl) implements an intuitive and recognizable method of entering or selecting a specific date. The main interface of the control is similar in functionality to a combo box. However, if the user expands the control, a month calendar control appears (by default), allowing the user to specify a particular date. When a date is chosen, the month calendar control automatically disappears.
If you need to display a picture for your application, Visual C++ provides a special control for that purpose.
