MSCE C++ 动态添加编辑框控件的思路

Question

老师好： 
 我现在想实现一个通过 用户确定一个数字，然后动态创建对应数量的编辑框控件，目前我考虑有两种方法实现 
 1、通过用户输入 ，真正实现动态创建。 
 2、提前根据业务 进行预判，设定一个最大合理数量的按钮，然后根据用户指定的数量 显示对应数量的控件。 
 但是目前都遇到一些问题，比如 1 的问题是 目前只了解R方式创建静态控件的方法， 
 2的问题是 没有找到可以 隐藏的属性。 
 
 辛苦老师 抽时间 解答一下！！！！！

方法2实现起来比较简单。在资源文件中如下所示设置ON|HIDDEN就能使一个控件初始状态为隐藏。 
 DialogBoxRsc DIALOGID_NewWidth =
{
 DIALOGATTR_DEFAULT, 32*XC, 5*YC,
 NOHELP, MHELP, NOHOOK, DIALOGID_EditPanel, "New Width",
	{
	{{18*XC, YC, 12*XC, 0}, Text, TEXTID_NewGapWidth, ON|HIDDEN, 0, "", ""},
	{{18*XC, YC, 12*XC, 0}, OptionButton,OPTIONID_NewWidth, ON|HIDDEN, 0, "", ""},
	{{ 6*XC, 3*YC, 8*XC, 0}, PushButton, PUSHID_AcceptNewWidth, ON, 0, "", ""},
	{{18*XC, 3*YC, 8*XC, 0}, PushButton, PUSHID_CancelNewWidth, ON, 0, "", ""},
	}
}; 
 后期通过代码控制一个控件(item)的显示与隐藏可分别调用mdlDialog_itemShow和mdlDialog_itemHide即可。

最简单粗暴的方法就是在你的MdlMain函数中打开对话框之前对g_uicode.zcount赋值为4。不过比较优雅的方法应该是在.r中定义

在.r中控制有一定的复杂性，请按如下步骤操作： 
 1. 在.h中定义一个新的资源类型和资源ID，如： 
 #define RTYPE_Ikg 'ikg_'
#define RSCID_Ikg 1
 
 2. 在.h中定义你的数据结构。如： 
 typedef struct sectiondata{
 long lengthLimit;
 double spanDirection;
 char gratingType[8];
 char barSize[8];
 double weightLimit;
 long gapUpLimit;
 long gapDnLimit;
 unsigned long surfaceType : 3;
 unsigned long unused : 29;
 char pmPrefix[12];
 long futureUse[6];
} SectionData;

typedef struct sectionLinkage {
 LinkageHeader header;
 SectionData data;
}SectionLinkage;

typedef struct supportdata{
 unsigned short supportType : 4;
 unsigned short direction : 1;
 unsigned short unused1 : 11;
 short unused2;
} SupportData;

typedef struct supportLinkage {
 LinkageHeader header;
 SupportData data;
}SupportLinkage;

typedef struct paneldata{
 char sectionChar;
 char panelStr[3];
} PanelData;

typedef struct panelLinkage {
 LinkageHeader header;
 PanelData data;
}PanelLinkage; //It's NOT used for Panel, it appends to Gap/Break/Cutout

typedef struct ikginfo
{
 char bandThickStr[15];
 char toePlateThickStr[15];
 char bandClearStr[15];
 char toePlateClearStr[15];
 char spanAngleStr[12];
 unsigned short	angleTol;
 unsigned short supportType:4;
 unsigned short angleLock :1;
 unsigned short gaplineType:1;
 unsigned short surfaceType:3;
 unsigned short gratingType:7;
 unsigned short barSize :8;
 unsigned short barSizeA :8;
 char gapMinStr[15];
 char gapMaxStr[15];
 char gapIncStr[15];
 short stdPanelWidthIndx;
 char remainWidthStr[15];
 char newGapWidthStr[15];
 unsigned short breakType :2;
 unsigned short autoBreak :1;
 unsigned short changePMMode : 3;
 unsigned short panelBgnNo :10;
 short breakWidth;
 char maxPanelWidthStr[15];
 char minPanelWidthStr[15];
 char topPanelWidthStr[15];
 char botPanelWidthStr[15];
 char brkOffsetStr[15];
 char pmNumberTXStr[15]; // PieceMark Text Height and Width
 char pmSizeTHStr[15], pmSizeTWStr[15];
 char dimTHStr[15], dimTWStr[15]; // ED, Gap, Break, Dimension Text Height and Width
 short oldMark, minMark, maxMark;
 char payCode[15];
 short tableRows;
 char exportFileName[MAXFILELENGTH];
 unsigned short billUnits : 2;
 unsigned short exportLock : 1;
 unsigned short	weightLimLock	: 1;
 unsigned short lengthLimLock : 1;
 unsigned short widthStdLock	: 1;
 unsigned short conflictLock	: 1;
 unsigned short	selectMode : 3;
 unsigned short	stdWidthDir : 1;
 unsigned short	treadWidth : 3;
 unsigned short	treadNote : 1;
 unsigned short calcWeightFlag : 1;
 char treadLength[15];
 double weightLim, lengthLim;
 short numSectDup[100];
 char nosingType[15];
 unsigned short applyToAll : 1;
 unsigned short EDWho : 1;
 unsigned short rightLeftEDLock :	1;
 unsigned short unused : 13;
 char treadGratingType[20];
 char treadFinishType[20];
 short treadQuantity;
 char drawNoStr[20];
 char projNoStr[20];
 char materialType[20];
 char finishType[20];
 char straightLoadToePlate[15];
 char circularLoadToePlate[15];
 char straightTrimToePlate[15];
 char circularTrimToePlate[15];
 char straightLoadBanding[15];
 char circularLoadBanding[15];
 char straightTrimBanding[15];
 char circularTrimBanding[15];
 char straightCutting[10];
 char circularCutting[10];
 char straightNosing[15];
 char pmPrefix[12]; // PieceMark Prefix String
 UInt32 pmColor;
} IKGInfo;
 
 3. 在.r中定义资源及其初始值： 
 resourceclass IKGInfo RTYPE_Ikg;

IKGInfo RSCID_Ikg =
// bandThickStr, toePlateThickStr, bandClearStr, toePlateClearStr
{ "1/8\"", "1/4\"", "1/16", "1/8",
// spanAngleStr, angleTol, supportType, angleLock, gaplineType, surfaceType, gratingType,
 "", 15, 1, 1, 0, 1, 1,
// barSize, barSizeA, gapMinStr, gapMaxStr, gapIncStr, stdPanelWidthIndx, remainWidthStr, newGapWidthStr, breakType,
 6, 6, "3/16", "1/2", "1/16", 0, "0", "1/4", 0,
// autoBreak, changePMMode, panelBgnNo, breakWidth, maxPanelWidthStr, minPanelWidthStr, topPanelWidthStr, botPanelWidthStr,
 1, 1, 1, 200, "", "", "", "",
// breakOffset, pmNumberTXStr, pmSizeTHStr, pmSizeTWStr, dimTHStr, dimTWStr, oldMark, minMark, maxMark
 "1/4", "3 3/4", "3", "2 1/4", "2 1/2", "2 1/2", 0, 0, 0,
// payCode, tableRows, exportFileName, billUnits, exportLock, weightLimLock, lengthLimLock, widthStdLock,
 "32.32.2A", 50, "C:\output", 0, 0, 0, 0, 0,
// conflictLock, selectMode, stdWidthDir, treadWidth, treadNote, calcWeightFlag,treadLength, weightLim, lengthLim,
 0, 0, 1, 0, 0, 0, "3'-6\"", 0.0, 0.0,
// numSectDup[100],
 1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,
 1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,
// nosingType, applyToAll, EDWho, rightLeftEDLock, unused,
 "A-3E", 0, 0, 0, 0,
// treadGratingType, treadFinishType, treadQuantity, drawNoStr, projNoStr, materialType, finishType,
 "WB1", "Mill", 1, "", "", "FIBERGLASS", "Mill",
// straightLoadToePlate, circularLoadToePlate, straightTrimToePlate, circularTrimToePlate
 "STP2.25", "CTP2", "STP2.25", "CTP2", 
// straightLoadBanding, circularLoadBanding, straightTrimBanding, circularTrimBanding
 "B.5AFT", "B10AC", "B.5AFT", "B10AC",
// straightCutting, circularCutting, straightNosing, pmPrefix, pmColor
 "SC", "CC", "A-3E", "301-", 5
};
 
 4. 在你的cpp的MdlMain中写如下代码装载默认值： 
 // Open 'ikg.ma' file for access to our dialog
 mdlResource_openFile (&_rfHandle, NULL, RSC_READWRITE);
 if (_rfHandle)
 ikgRscP = (IKGInfo *)mdlResource_load (_rfHandle, RTYPE_Ikg, RSCID_Ikg);
	_ikg = *ikgRscP;
 mdlResource_free (ikgRscP); 
 其中的_ikg为全局变量IKGInfo _ikg;
