生成二维码

在生成一维码的基础上，再做二维码，感觉就是重复劳动而已。

但也有提高。

首先把诸多的类型转化为字符串，通过资源配置方式来设置，这样就减轻了程序的工作。

当然，这个首先是顺便的，因为在实现之前，看了一下Demo程序，发现不同类型的二维码，它们可能包括同一个属性名称，如MinSize和MaxSize

在MicroPDF417类型下，它的可取值为mpSize_1_11,mpSize_1_14,mpSize_1_17,mpSize_1_20,mpSize_1_24,mpSize_1_28,mpSize_2_8,mpSize_2_11,mpSize_2_14,mpSize_2_17,mpSize_2_20,mpSize_2_23,mpSize_2_26,mpSize_3_6,mpSize_3_8,mpSize_3_10,mpSize_3_12,mpSize_3_15,mpSize_3_20,mpSize_3_26,mpSize_3_32,mpSize_3_38,mpSize_3_44,mpSize_4_4,mpSize_4_6,mpSize_4_8,mpSize_4_10,mpSize_4_12,mpSize_4_15,mpSize_4_20,mpSize_4_26,mpSize_4_32,mpSize_4_38,mpSize_4_44

而在DataMatrix类型下，它的可取值为dmSize_09_09,dmSize_11_11,dmSize_13_13,dmSize_15_15,dmSize_17_17,dmSize_19_19,dmSize_21_21,dmSize_23_23,dmSize_25_25,dmSize_27_27,dmSize_29_29,dmSize_31_31,dmSize_33_33,dmsize_35_35,dmSize_37_37,dmSize_39_39,dmSize_41_41,dmSize_43_43,dmSize_45_45,dmSize_47_47,dmSize_49_49

刚开始以为是个例，结果发现居然有很多。

那还能用一个类来实现吗？

经过琢磨，发现还真能用一个类来实现：

class TBarCode2D : public TCbwImage {

    typedef TCbwImage inherited;

    CBW_PUBLISH_BARCODE(UnicodeString, BarCode, FBarCode, SetBarCode);

    CBW_PUBLISH_BARCODE(UnicodeString, Type, FType, SetType);

    CBW_PUBLISH_BARCODE(int, Module, FModule, SetModule); // AztecCode,AztecRunes,HanXinCode

    CBW_PUBLISH_BARCODE(bool, ReviseVersion5, FReviseVersion5, SetReviseVersion5); // HanXinCode

    CBW_PUBLISH_BARCODE(int, MinSegments, FMinSegments, SetMinSegments); // CompactMatrix

    CBW_PUBLISH_BARCODE(int, MaxSegments, FMaxSegments, SetMaxSegments); // CompactMatrix

    CBW_PUBLISH_BARCODE(UnicodeString, StretchOrder, FStretchOrder, SetStretchOrder); // CompactMatrix

    CBW_PUBLISH_BARCODE(int, StartWidth, FStartWidth, SetStartWidth); // CompactMatrix

    CBW_PUBLISH_BARCODE(int, StopWidth, FStopWidth, SetStopWidth); // CompactMatrix

    CBW_PUBLISH_BARCODE(UnicodeString, Placement, FPlacement, SetPlacement); // CompactMatrix

    CBW_PUBLISH_BARCODE(bool, AllowKanjiMode, FAllowKanjiMode, SetAllowKanjiMode); // QrCode

    CBW_PUBLISH_BARCODE(UnicodeString, EncodePolicy, FEncodePolicy, SetEncodePolicy); // QrCode

    CBW_PUBLISH_BARCODE(int, MinRows, FMinRows, SetMinRows); // PDF417

    CBW_PUBLISH_BARCODE(int, MaxRows, FMaxRows, SetMaxRows); // PDF417

    CBW_PUBLISH_BARCODE(int, MinColumns, FMinColumns, SetMinColumns); // PDF417

    CBW_PUBLISH_BARCODE(int, MaxColumns, FMaxColumns, SetMaxColumns); // PDF417

    CBW_PUBLISH_BARCODE(int, RowHeight, FRowHeight, SetRowHeight);     // PDF417

    CBW_PUBLISH_BARCODE(bool, Compact, FCompact, SetCompact); // PDF417

    CBW_PUBLISH_BARCODE(UnicodeString, DefaultEncodeMode, FDefaultEncodeMode, SetDefaultEncodeMode); // MicroPDF417

    CBW_PUBLISH_BARCODE(UnicodeString, DefaultTextEncodeMode, FDefaultTextEncodeMode, SetDefaultTextEncodeMode); // MicroPDF417

    CBW_PUBLISH_BARCODE(bool, UseECIDescriptor, FUseECIDescriptor, SetUseECIDescriptor); // MicroPDF417

    CBW_PUBLISH_BARCODE(UnicodeString, InitialMode, FInitialMode, SetInitialMode); // Code16K

    CBW_PUBLISH_BARCODE(int, SeparatorBarHeight, FSeparatorBarHeight, SetSeparatorBarHeight); // Code16K

    CBW_PUBLISH_BARCODE(bool, AutoCheckDigit, FAutoCheckDigit, SetAutoCheckDigit); // RSS-14

    CBW_PUBLISH_BARCODE(int, TotalHeight, FTotalHeight, SetTotalHeight); // RSS-14

    CBW_PUBLISH_BARCODE(UnicodeString, Style, FStyle, SetStyle); // RSS-14

    CBW_PUBLISH_BARCODE(bool, Link2D, FLink2D, SetLink2D); // RSS-14

    virtual void __fastcall DoAddToXmlNode(CbwXmlNode * node);

    virtual void __fastcall DoGetFromXmlNode(CbwXmlNode * node, int& index);

    virtual void __fastcall Clone(TCbwObject * dest);

    virtual UnicodeString __fastcall GetHidePropertyNames();

    virtual UnicodeString __fastcall GetTypeResources(UnicodeString propertyName);

    // 返回不被显示的属性名列表

public:

    __fastcall TBarCode2D();

    __fastcall ~TBarCode2D();

    __fastcall TBarCode2D(TBuildType buildFlag);

    static TCbwObject * Build();

    void __fastcall Initial();

};

再辅之以资源配置，OK了。

使用方法：

1. 选择插入对象类型为二维码

1. 在工作区拖动画出目标区域
2. 在属性浏览器中输入条码内容，如http://finance.qq.com/a/20130905/012251.htm，将生成二维码，
3. 可以继续修改二维码对象的各个属性，如条码颜色、模块等，以下为条码颜色为红色、模块为3的效果：

基本方法如此，下面为几个二维码的截图

才发现，原来常见的二维码都是QrCode类型，其它的类型还多着呢。

顺便把控件的时间限制给Crack了。
