In vb the call looks like this

ExcelApp---Excel.Application

dim MyArray(2)as double
MyArray(1)=1
MyArray(2)=2
ExcelApp.Run("SomeFunc",MyArray)
Works well

How can I do that in MFC
My code is like:
_______________________________________
COleVariant FuncName;FuncName.bstrVal= SysAllocString(L"SomeFunc");
COleVariant MyArray;
double tmp[2]={1,2};
PutValues(&MyArray,tmp,2);
m_ExcelApp.Run(FuncName,MyArray);


The put values function is:
_______________________________________
void PutValues(COleVariant  *ThisArray, double *Arr, long nCount)
{
      int i = 0;      
      long *palDims = 0;
      double      rValue = 0.0;
      SAFEARRAY *psaData = 0;
      SAFEARRAYBOUND *pabound = 0;
      HRESULT      hRes = 0;      

      VariantInit( ThisArray );
        pabound = (SAFEARRAYBOUND *) malloc( 2 * sizeof(SAFEARRAYBOUND) );
      palDims = (long *) malloc( 2 * sizeof(long) );
      if( pabound && palDims )
            {
            pabound[0].cElements = nCount;
            pabound[0].lLbound = 0L;
            pabound[1].cElements = 1;
            pabound[1].lLbound = 0L;
            psaData = SafeArrayCreate( VT_R8, 2, pabound );
            for( i = 0; ( i < nCount) && ( hRes == S_OK) ; i++ )
            {
                palDims[0] = i;
              palDims[1] = 0;
              hRes = SafeArrayPutElement( psaData, palDims,&Arr[i]);
            }
             ThisArray->parray = psaData;
                ThisArray ->vt = VT_R8;
            ThisArray->vt|= VT_ARRAY;
            }
            free( pabound );
            free( palDims );
}
