these are nine intrinsic controls are pretty

your learning with these and then branch
out .

picture box , text box, list box ,label , combo
box , option button.

6. STANDARD ACTIVEX CONTROLS
The Learning edition of Visual Basic contains a
number of ActiveX controls (referred to as
standard ActiveX controls) that allow you to add
advanced features to your applications. ActiveX
controls have the file name extension .ocx and
can be used in your project by manually adding
them to the toolbox.
The following table summarizes the standard
ActiveX controls available in the Learning edition
of Visual Basic.

7. Icon Control

Class name Description
ADO Data
Control
ADODC
Creates a connection to a database

DataSource property of other
controls such as the DataGrid.
Common

Provides a standard set of dialog
boxes for operations such as
opening and saving files, setting
print options, and selecting colors
and fonts.
DataCombo DataCombo
Provides most of the features of
the standard combo box control,
plus increased data access
capabilities.
DataGrid DataGrid

data-bound to a data source such
as the ADO Data Control. Reading
and editing the recordset is
possible.
DataList DataList Provides most of the features of

Microsoft
Hierarchical
FlexGrid
MSHFlexGrid A read-only grid control that can be
bound the Data Environment
designer to show hierarchical
recordsets.

8. OTHER CONTROLS
Other ActiveX controls included with all
versions of Visual Basic are documented
in the Component Tools Guide, and
include the following: ImageCombo,
ImageList, ListView, ProgressBar, Slider,
Statusbar, TabStrip, Toolbar, and
TreeView.

9. ADDING AND REMOVING ACTIVEX CONTROLS
You move ActiveX controls to and from the
toolbox using the following procedures.
To add an ActiveX control to the toolbox
 From the Project menu, choose Components.
 Select the check box next to the name of the
.ocx control, and then choose OK. Once a
control is placed in the toolbox, you can add it to
a form just as you would an intrinsic control.

10. To remove an ActiveX control
 Remove all instances of the control from the forms
in your project. Delete any references to the
control in the project's code. If references to a
deleted control are left in your code, an error
message will display when you compile the
application.
 From the Project menu, choose Components.
 Clear the check box next to the name of the .ocx
control, and then choose OK. An error message
will display if there are remaining instances of the
control in your project.

11. COMMON DIALOG CONTROL:
 VB provides user facility of using in-built dialog boxes in
application. Hence user is saved from the job of design
his own dialog boxes. He has just to use common dialog
control on form and call appropriate methods. Common
dialog control is a special control. It provides its services
to application but it need not to be displayed at form at
run time.
 Common dialog control is a component that allows us to
access inbuilt libraries.
 Common dialog control provides an interface between
visual basic and the procedures in the Microsoft windows.

12. TO USE THE COMMON DIALOG CONTROL:
 Add the common dialog control to the toolbox by
selecting components from the project menu.
Locate and select the control in the controls
tabbed dialog, then click the OK button.
 On the toolbox, click the common Dialog control
and draw it on a form. When you draw a
common dialog control on a form, it
automatically resize itself. Like the timer control,
this dialog is invisible at run time.

13. The common dialog control allows you to display these
commonly used dialog boxes:
 Open
 Save As
 Color
 Font
 Print
 Help

14.  File open and file save common dialog
control: File common dialog doesn’t display all files in any given
folder normally. File display are limited to those recognized by
application. Filter property determines the file to be displayed in File
Open or File Save dialog box. DefaultExt property is used to specify
the type of file to be displayed.
 Color Common Dialog Control: It has single
property color which returns color selected by user or sets initially
selected color when dialog box opened.

15.  Help common Dialog Control: Before
using help common dialog box , user must have help files.
These files either can be prepared by user or in-built.
 To display common dialog box through code, its action
