HOWTO:在 Visual Basic 中自动运行 Microsoft Excel

针对 Office 2003 的支持已终止

Microsoft 已于 2014 年 4 月 8 日终止了针对 Office 2003 的支持。该更改已影响到您的软件更新和安全选项。 了解这一措施对于您的含义以及如何继续保持受保护状态。

概要
本文演示如何通过使用 Visual Basic 的自动化功能创建和操纵 Excel。
更多信息
有两种方法可以控制自动化服务器:通过使用晚期绑定或早期绑定。若使用晚期绑定,则在声明运行时和自动化服务器为“对象”之前不绑定方法。若使用早期绑定,则您的应用程序在设计阶段知道要与之通信的对象的确切类型,并可以作为一个特定类型声明其对象。本示例使用早期绑定,早期绑定被认为是在多数情况下都很适用的方法,因为它可以提供更高的性能和更好的类型安全性。

要早期绑定到自动化服务器,您需要设置对该服务器类型库的引用。在 Visual Basic 中,该操作是通过“项目”|“引用”菜单下的“引用”对话框完成的。对于本示例,您需要向 Excel 的类型库中添加一个引用,然后才能运行代码。关于如何添加引用,请参见下面的步骤。

生成自动化示例

  1. 启动 Visual Basic,新建一个标准 EXE 项目。默认情况下会创建 Form1。
  2. 选择“项目”|“引用”以显示“引用”对话框。向下滚动列表,直到找到“Microsoft Excel 10.0 对象库”,然后选择此项目以向 Excel 2002 中添加一个引用。如果列表中未显示该项目,请检查是否已正确安装了 Excel 2002。

    注意:如果正在自动运行 Microsoft Office Excel 2003,则该类型库在“引用”列表中显示为“Microsoft Excel 11.0 对象库”。如果正在自动运行 Microsoft Excel 2000,则该类型库在“引用”列表中显示为“Microsoft Excel 9.0 对象库”,如果您使用的是 Microsoft Excel 97,则该类型库显示为“Microsoft Excel 8.0 对象库”。
  3. 单击“确定”,关闭“引用”对话框。
  4. 将 CommandButton 添加到 Form1 中。
  5. 在 Form1 的代码窗口中,插入下面的代码:
       Option Explicit      Private Sub Command1_Click()      Dim oXL As Excel.Application      Dim oWB As Excel.Workbook      Dim oSheet As Excel.Worksheet      Dim oRng As Excel.Range            'On Error GoTo Err_Handler         ' Start Excel and get Application object.      Set oXL = CreateObject("Excel.Application")      oXL.Visible = True         ' Get a new workbook.      Set oWB = oXL.Workbooks.Add      Set oSheet = oWB.ActiveSheet         ' Add table headers going cell by cell.      oSheet.Cells(1, 1).Value = "First Name"      oSheet.Cells(1, 2).Value = "Last Name"      oSheet.Cells(1, 3).Value = "Full Name"      oSheet.Cells(1, 4).Value = "Salary"         ' Format A1:D1 as bold, vertical alignment = center.

Set oRng = oSheet.Range("C2", "C6")      oRng.Formula = "=A2 & "" "" & B2"          ' Fill D2:D6 with a formula(=RAND()*100000) and apply format.
