解读时先取线条粗细,再取间隙宽窄,如:
上图中的字符*就可以解读为 001101000,字符3解读为 110000100
下面就是我们给出的子过程:
注释: 将字符串 strBarCode 对应的条形码输出到缺省打印机
Private Sub PrintBarCode( _
ByVal strBarCode As String, _
Optional ByVal intXPos As Integer = 0, _
Optional ByVal intYPos As Integer = 0, _
Optional ByVal intPrintHeight As Integer = 10, _
Optional ByVal bolPrintText As Boolean = True _
)
注释: 参数说明:
注释: strBarCode - 要打印的条形码字符串
注释: intXPos, intYPos - 打印条形码的左上角坐标(缺省为(0,0),坐标刻度为:毫米)
注释: intHeight - 打印高度(缺省为一厘米,坐标刻度为:毫米)
注释: bolPrintText - 是否打印人工识别字符(缺省为true)
注释: "0"-"9","A-Z","-","%","contentquot;和"*" 的条码编码格式,总共 40 个字符
Static strBarTable(39) As String
