C # printing and designing labels (bar codes) (I ),
I believe that companies of a relatively small scale have entered or are entering the informatization process. Especially in manufacturing enterprises, a bar code printing function is indispensable. Most of these applications use banma printers, so we will encounter the problem of printing. I have been engaged in ERP, MES and other systems for many years, and have learned some of the company's practi

The value of a hash is speed. We use arrays to hold key information, which is not the key itself, but rather generates a number (hash code) from the key objectas an array subscript. Because the capacity of the array is fixed, and the size of the hash container is variable, different keys can produce the same array subscript (hash code). That is, there may be conflicts (and, of course, exceptions, such as Enummap and Enumset). Therefore, the value of the array holds a list (reference) that holds

invade mobile devices in the most unexpected way, for example, through QR codes. QR code is also a kind of barcode, but it has more powerful storage ability. Cyber criminals disguise the SMS Trojan as a common Android software by incorporating malicious links into QR codes. After the QR code is scanned, the mobile device will automatically download the malicious files, and through the form of SMS, a large
