How can I create an XlfOper with a multi dimensional array ?

[Adjriou Belak]

Hi,

 

 I try to display in Excel this arrays :

 

  std::vector<double> df = market.discountFactors();
  std::vector<double> zc = market.zeroCoupons();
  std::vector<Date> dt = market.maturities();

 

  char * *dfs  =new char*[df.size()];
  char * *zcs =new char*[zc.size()];
  char * *dts =new char*[dt.size()];

  for(int i=0; i< df.size();i++)
   printf(dfs[i],"%c",df[i]);

  
  for(int j=0; j< zc.size();j++)
   printf(zcs[j],"%c",zc[j]);  

 

  for(int k=0; k< dt.size();k++)
   itoa(dt[k].serialNumber(),dts[k],10);  

 

  char ** results[3];
  results[0] = dts;
  results[1] = dfs;
  results[2] = zcs;
    

  return XlfOper(df.size(),3,results);

 

And I've got this message :

warning C4800: 'char ** ' : forcing value to bool 'true' or 'false' (performance warning)
        c:\adjriou\xlw\xlw\xlfoper.h(79) : see reference to function template instantiation 'class XlfOper &__thiscall XlfOper::Set(unsigned short,unsigned char,char ***  )' being compiled

And when I run excel, I have TRUE, TRUE .... ?

 

How can I create an XlfOper with a multi dimensional array ?

 

Thanks a lot for your help.

 

Regards.

I don't know the Excel API, but you probably want to use sprintf in the  
above loop...
