二维码已经能够识别，是基于开源的zxing实现的。从使用的角度来说，能够生成一下一二维码，也是很爽的事。
以前做公安行业项目时，接触过条码打印机，是不是就是这里所说的一维码呢？
当然，没有必要老提当年的事。做技术的，做得越久，就会更加发现以前做的都有点垃圾，灰飞烟灭后，发现只是手留余香，现在做什么技术方面的事情能够比较快地实现而已。
花了一天时间，在cptang发来的控件的基础上，完整地实现了生成一维码功能。正准备再接再厉实现二维码，结果用户与我联系，说今天下午有个重量级用户来，要给他演示原理示教系统，准备在河北廊坊推广。倒是好事。那就先把二维码放下，实现起来应该还需要半天时间。
生成一二维码，首先是界面，在插入栏中加入图标即可，剩下的是设置一下Tag、OnClick事件。
再加入一维码类：
class TBarCode1D : public TCbwImage {
typedef TCbwImage inherited;
virtual void __fastcall DoAddToXmlNode(CbwXmlNode * node);
virtual void __fastcall DoGetFromXmlNode(CbwXmlNode * node, int& index);
virtual void __fastcall Clone(TCbwObject * dest);
void __fastcall CreateBmpFile();
public:
__fastcall TBarCode1D();
__fastcall ~TBarCode1D();
__fastcall TBarCode1D(TBuildType buildFlag);
static TCbwObject * Build();
void __fastcall Initial();
};
下来就是逐个研究其数据成员。
运行一下控件的示例程序：
一个个属性研究(这一天时间主要就花在这上面了)，在之前编程的基础上，很快可以分门别类地实现各个成员：
enum TBarCode1DType {
_Codabar = 0, _Code11 = 1, _Code25Industrial = 2, _Code25Invert = 3, _IATA = 4, _Code25Interleaved = 5,

CBW_PUBLISH_BARCODE(bool, InterGap, FInterGap, SetInterGap);
CBW_PUBLISH_BARCODE(bool, Bidirectional, FBidirectional, SetBidirectional);
};
具体的事宜交给DrGraph软件去完成。
最终实现效果：
剩下的事，就是把不该出现的属性从属性浏览器中去掉，并把属性名称在资源文件中配置为中文，让自己的用户用得舒服一点。
