开发可复用的从Domino中导出数据到Excel的类

在domino开发中我们不可避免的要和报表打交道，一般就是生成各种Excel报表，本人主要为了自己在开发中方便，简单实现了一个基本类，现在功能有限，当然这个类我慢慢的根据以后遇到的需求逐渐完善。

Const EXCEL_APPLICATION        = "Excel.application"

Private Const BASEERROR                                                = 1200
'Private Const ERROR_NOSUCHCELL                            = BASEERROR + 0
'Private Const ERRORTEXT_NOSUCHCELL                    = "Excel Report - Could not get data from cell."

Const REG_97            = "Software\\Microsoft\\Office\\8.0\\Common\\InstallRoot"                    'Registry Key Office 97
Const REG_2000        = "Software\\Microsoft\\Office\\9.0\\Common\\InstallRoot"                    'Registry Key Office 2000
Const REG_XP            = "Software\\Microsoft\\Office\\10.0\\Common\\InstallRoot"                    'Registry Key Office XP
Const REG_2003        ="Software\\Microsoft\\Office\\11.0\\Common\\InstallRoot"                    'Registry Key Office 2003

Const NAME_97        = "Office 97"
Const NAME_2000        = "Office 2000"
Const NAME_XP        = "Office XP"
Const NAME_2003        = "Office 2003"
