用C++或者VB写一个程序读取一个excel文件的sheet1与sheet2，并使sheet1与sheet2对应的地方相乘

然后再累加求和。 如sheet1的A1与sheet2的A1相乘，sheet1与sheet2都是9行3列。
谢谢大神！！！

Answer 1

Sub aaa()

  If Application.Dialogs(xlDialogOpen).Show Then

     On Error Resume Next

        For C = 1 To 3

            For R = 1 To 9

               ThisWorkbook.Sheets(1).Cells(R, C) = ActiveWorkbook.Sheets(1).Cells(R, C).Value

               ThisWorkbook.Sheets(2).Cells(R, C) = ActiveWorkbook.Sheets(2).Cells(R, C).Value

               ThisWorkbook.Sheets(3).Cells(R, C) = ThisWorkbook.Sheets(1).Cells(R, C).Value * ThisWorkbook.Sheets(2).Cells(R, C).Value

            Next R

       Next C

    ActiveWorkbook.Close (False)

    ThisWorkbook.Save

    MsgBox "Done！" 

  End If

End Sub

需要包含#include"afxdao.h",只能打开xls的
CDaoDatabase m_db;
CDaoRecordset *m_Set;
COleVariant var;
try
{
m_db.Open(path,0,0,"Excel 4.0");
}
catch(CDaoException *e)
{
MessageBox(e->m_pErrorInfo->m_strDescription,"打开失败");
e->Delete();
}
m_set=new CDaoRecordset(&m_db);
m_set->Open(-1,"select * from [sheet1$]",0);
m_set->GetFieldValue(index,&var);
/*自己写*/
m_set->Clsoe();
m_db.Clsoe();
