这下面是一段代码

#include "CFont0.h"
#include "CApplication0.h"
#include "CFont1.h"
#include "CSelection0.h"
#include "COMathFrac.h"
#include "CApplication.h"
#include "COMathRad.h"
#include "COMathScrPre.h"
#include "COMathDelim.h"
#include "CRange0.h"
#include "COMathFunction0.h"
#include "COMathFunctions0.h"

 CCodeCoversion CodeCov;
 StringMatch strmatch;
 
 CSelection0 sel;
 COMathFrac mathFrac;
 COMathRad mathRad;
 COMathScrPre mathScrPre;
 COMathDelim mathDelim;
 CRange0 rang;
 COMathFunction0 mathFunction;
 COMathFunctions0 mathFunctions;

  wstring patten1 = TEXT("[SX(](.*?)[][SX)]");
  wstring temp1=strmatch.WsearchResult(temp, patten1);
  CString str(temp1.c_str());
  CString left=str.Left(1);
  CString right=str.Right(1);
  rang.put_Text(left);
  mathFrac =mathFunctions.Add(rang,7,NULL,NULL);//代码运行到这里错误

  mathFrac.get_Num();  
  rang.put_Text(right);
  mathFrac.get_Den();  
  mathFrac.put_Type(1);  

看得懂吗？

temp1为一字符串，运用正则搜索，然后调用wps的接口类，

我现在想要得到字符串后变成分式，我这样不对，该怎样弄呢？
