Extended Control to print RM4SCCIf most of the functionality required in your task is already identical to .NET RM4SCC Generator Control, you can simply create your own control that prints RM4SCC by extending Onbarcode .NET RM4SCC Generator Control. The new control created by you is called Extended Control, and .NET RM4SCC Generator Control is the base control of the extended Control.
The Extended Control encapsulates the functionality of .NET RM4SCC Generator Control. You could make your own choice on whether to change the graphical user interface of the base control according to your task requirement. You can make your own user interface design and modification as your want.
The Extended Control retains the High Quality RM4SCC Generation from .NET RM4SCC Generator Control.
Composite Control to Generate RM4SCCIf you want to combine the functionality of multiple Windows Forms controls including .NET RM4SCC Generator into a single control, you'd better create a Composite Control by encapsulating the collection of controls.
The common container is known as user control while these controls with target functionality are called constituent controls.
The composite Control inherits the High Quality RM4SCC Generation from .NET RM4SCC Generator Control, while it could also inherit functionality from other existing controls shipped by Visual Studio or installed on .NET framework.
Background informationRM4SCC, also known as CBC which is short for Cunstomer Bar Code, is a barcode symbology. It is primarily used by the Royal Mail for it has the ability to clean the mails. RM4SCC makes it possible for the UK postcodes together with Delivery Point Suffixes to be read by a machine at a fast speed rather easily.
Royal TNT PostA version which is a bit modified named KTX (Klant Index ) is used by Royal TNT Post. What makes Royal TNT Post different from others is that no start and end symbols and checksum have ever been used. Besides, it can help separate the house number and provide with an X. Normally, it can be seen below the address.
GuidelinesGenerally speaking, strict and organized guidelines have been used to control the usage of these barcodes, which makes it possible for the numbers to be read by machines maximumally. At the same time, Royal Mail's Cleanmail system can use the RM4SCC barcode as well. It is used as an alternative to OCR fonts which are readable. Apart from that, business will also have access to send a great number of letters rather easily and cheaply. One thing that needs to be noticed is that the barcode is made up of a start character, postcode, the Delivery Point Suffix, a checksum character, and a stop character.
EncodingTypically, every character consists of four bars. Two of them extend upward and the other two stretch downward. Each half of the long bars is able to be allocated weights of 4210 in order to generate a digit from one to six. 36 possible symbols which include 10 digits and 26 letters are given by the combination of the top and bottom halves.
ChecksumThere are three ways to calculate the check symbol. The first one is to sum up the top and bottom half values separately. Modulo is considered as the second way of computing the symbol. What comes last is combing the final numbers into a complete symbol. For instance, If the half values are 26114512, then this adds up to 22=6กม3+4,and as a result,a top value of 4 can be obtained. If the bottom half values are 64224625, and this sums up to 31=6กม5 + 1. As is seen from the above, one is the half value of the check symbol's bottom, which goes with the letter I.
