• Components may be added as an Inserted Object or as an ActiveX control
• Data binding allows source data from a field in an MSAccess Table
• Saves graphic files in BMP, EPS, PCX, PNG or WMF formats.
• Checkdigits may be calculated automatically and shown or hidden (for codetypes which permit this).
• Barcodes may be rotated left or right or inverted.
• Wide/Narrow ratios may be adjusted, and margin indicators and bearer bars may be turned on/off for codes which support these features. Bar width control for wet-ink printing allows 0 - 50% width reduction.
• Font properties, text justification, bar colour and background colour may be user selected.
• Nominal size option for codes which specify a nominal (100%) size.
• ISBN barcodes may be generated from ISBN numbers including the new ISBN-13.
• Does not use MFC dlls or additional dlls*.
• 2D versions can produce mirror image barcodes

Use as an object

May be added to most applications using the Insert Object method, and properties set by double clicking on the barcode image - see images of Property pages.

Or use as an ActiveX Control

dLSoft Active Barcode Components may be placed as an ActiveX Control into programming environments, such as Visual Basic, Delphi, or Microsoft Office:

Typical VB code sample:

Axbarcode1.ImageHeight = Val(Edit1.Text)
Axbarcode1.ImageWidth = Val(Edit2.Text)
Axbarcode1.Xunit = 0
Axbarcode1.CodeType = Combo1.ListIndex
Axbarcode1.Caption = Text1.Text
Image1.Picture = Axbarcode1.Picture

Images may be saved to disk in several formats under program control.

Using Active Barcode Components in Visual Basic 6

Adding the control to a Visual Basic form

To add an Active Barcode Component control to a Visual Basic form, select Components from the VB Project menu. If dLSoft 1D Barcode control module is displayed in the list of available controls, then ensure that it is checked. If it does not appear in the list user the Browse button to locate it in its installation directory (or in Windows System or System32), then check its name in the list. Once checked, an icon representing the component will appear in the toolbox.

Clicking on the Active Barcode Component’s icon in the toolbox causes the cursor to change to a cross. Positioning the cross on a Visual Basic form, holding down the left mouse button and dragging the cursor down and to the left, then releasing the mouse button, causes a rectangle to be drawn on the form. An image of a (default) barcode will be shown within this rectangle. You may wish to use this image of the component. Alternatively you may hide the component (by setting its Visible property to false) and use the components methods and properties to create an image that is placed elsewhere on the form - as in the sample Visual Basic program that is supplied with the component and uses code of the form:

Axbarcode1.ImageHeight = i
Axbarcode1.ImageWidth = j
Axbarcode1.Xunit = 0
Axbarcode1.CodeType = type
Axbarcode1.Caption = Text
Image1.Picture = Axbarcode1.Picture

A single Visual Basic Form may contain any number of Active Barcode Components. The first to be added will be called Axbarcode1, the second Axbarcode2, and so on; the names may be changed by the user by modifying the Name property within the Visual Basic Properties box.
Alternatively an array of controls may be created using the Index property.

Using the Active Barcode Components in Access

Microsoft Access is a database that holds data in tables. When an Active Barcode Component is added to an Access Form or Report as an ActiveX control, the component's Properties list allows the user to select one of the Table fields as a Source of the components data - ie the data to appear in the barcode.

The Record Source may be selected from a drop-down list in the form or report's properties list, and the barcode's Control Source may be selected from the drop down list in the component's properties list. All other properties (code type, size, font, etc.) can be selected from the other entries in the Access Properties list at design time. This allows barcode creation to be fully automatic for every record in a database.

Of course, a barcode image that is the same on every record may also be created - by ensuring that the Control Source entry on the component's properties list is empty, and the required data is entered for the Caption property.

Active Barcode Component properties for a barcode image on a form or report may also be set at run-time using Visual Basic module code to modify the control's properties.

A sample Access database is included with the distribution
