Put a 2D barcode component TBarcode2D_CCA, TBarcode2D_CCB, or TBarcode2D_CCC to your form.
Also, put a TDBBarcode2D component to the form and link the 2D barcode component to the TDBBarcode2D component if the database support is required.
Put a linear barcode component to your form. The TBarcode2D_RSS14, TBarcode2D_RSSLimited, and TBarcode2D_RSSExpanded can be used as the linear component. The TBarcode1D_UPCA, TBarcode1D_UPCE, TBarcode1D_UPCE0, TBarcode1D_UPCE1, TBarcode1D_EAN8, TBarcode1D_EAN13, and TBarcode1D_EAN128 components can be used as linear barcode component too, they are in the 1D Barcode VCL Componnts package. Note, only the TBarcode1D_EAN128 component can be used as the linear barcode component if you use the TBarcode2D_CCC as the 2D barcode component.
Also, put a TDBBarcode2D component (the linear barcode component is the TBarcode2D_RSS14, TBarcode2D_RSSLimited, or TBarcode2D_RSSExpanded) or a TDBBarcode1D component (if the linear barcode component is the TBarcode1D_UPCA, TBarcode1D_UPCE, TBarcode1D_UPCE0, TBarcode1D_UPCE1, TBarcode1D_EAN8, TBarcode1D_EAN13, or TBarcode1D_EAN128) to the form and link the linear barcode component to it if the database support is required. The TDBBarcode1D component is in the 1D Barcode VCL Componnts package.
Set the Linear property of the 2D barcode component to the linear barcode component.
Put a TImage control to your form, or put a TQRImage or TQRGzImage control to your report.
Set the Image property of the 2D barcode component to the TImage, TQRImage, or TQRGzImage control.
If you use the TBarcode1D_UPCA, TBarcode1D_UPCE, TBarcode1D_UPCE0, TBarcode1D_UPCE1, TBarcode1D_EAN8, TBarcode1D_EAN13, or TBarcode1D_EAN128 component as the linear barcode component, its Height property should be set to a value larger than zero.
The Image property of linear barcode component should not be normally set, the Image property's value of the 2D component will be used.
