I don't know what you're saying, and your code is missing the most important line - the one at the top which tells me which procedure it is and which event it's handling.
Normally, when you enter data in somewhere you enter all the individual characters, then you enter a Carriage Return (The enter key) - often abbreviated to CR. The ASCII code for this is 13 decimal or 0D hexadecimal.
To be able to be used in systems designed for keyboadrd entry, the bar code readers often send data that includes a CR at the end, so as to tell whatever software that is reading the data, that it has finished its entry. These devices are often configurable as different software needs/requires different ways to indicate that it's finished on a particular entry. This you need to find out.
The dummy/test form gives you a means to determine this if you look at the values passed to the event procedure when using the device. I'm not sure what more I can say to simplify this, but if you have any specific questions that I can understand I will happily try.
