I. CCD scanners use the principle of photoelectrical coupling (CCD) to imaging bar code printed patterns and then decode them. Its advantages are: No rotating shaft, motor, long service life; low price. When selecting a CCD scanner, two parameters are most important: 1. scene Depth: Because CCD imaging is similar to a camera, if you want to increase the depth of field, you need to increase the lens accordingly, so that the size of CCD is too large and inconvenient to operate. Good CCD should be

. I went and fell into the trap again. In addition, it is too deep. When you open the decodecomponent demo, it is displayed that the interface control is incorrect, the property is incorrect, my God, and their own items are all incorrect !!!! I am studying, and studying. Finally, dx, Let's guess how to solve this problem ????? Install sdk7 and change the control to sdk7. Open the sdk8 demo !!!! The upgrade is understandable. Please, we have a strict attitude towards a large company. Upgrade

Digester (); If you encounter The above code simply shows the reader some of the main points of digester processing XML, mainly explaining some patterns and matching rules. In short, digester is a kind of JavaBean that transforms an XML into something similar to that of the XML structure. You can think of the XML root element as a JavaBean, the root element of the attribute is the JavaBean of the various Field, when the root element has other child tag, but also think of this sub-tag as a new
