VB.NET创建外部excel对象
请教下我定义一个excel的application对象的应用
dim x1App as Excel.application就出错了
是不是要引用什么类啊
__________________________________________________________________________
up
__________________________________________________________________________
Imports Excel.Constants
Imports Excel.XlBordersIndex
__________________________________________________________________________
系统设定 追加 --〉com --> Microsoft Excel 11.0 Object Library 双击
确定
然后在代码的最上面加
Imports Excel.Constants
Imports Excel.XlBordersIndex
__________________________________________________________________________
Interop.Excel.dll
Interop.Microsoft.Office.Core.dll
Interop.Office.dll
Interop.VBIDE.dll
加载这四个文件就可以了
__________________________________________________________________________
要引用类库里的 Excel.Constants、 Excel.XlBordersIndex类
__________________________________________________________________________
只有Imports Excel.Form1
没有
Imports Excel.Constants
Imports Excel.XlBordersIndex
我在引用中也引用了Microsoft Excel 11.0 Object Library
怎回事
