引言

VBScript（Visual Basic Scripting Edition）是一种由微软开发的脚本语言，它是Visual Basic家族的轻量级成员。作为一种解释型脚本语言，VBScript在Windows环境中有着广泛的应用，特别是在系统管理、网页开发（特别是ASP技术）和自动化任务方面。本文将带你从零开始，逐步深入VBScript的世界，帮助你掌握这门脚本语言的核心技术，并通过丰富的应用实例提升你的编程能力，最终成为一名专业的VBScript开发者。

VBScript概述

VBScript是一种基于组件对象模型（COM）的脚本语言，它继承了Visual Basic的基本语法，但更为简洁和灵活。VBScript最初设计用于网页客户端脚本，但由于安全考虑，现代浏览器已不再支持它。然而，在Windows系统管理和服务器端开发（特别是ASP）领域，VBScript仍然扮演着重要角色。

VBScript的特点

• 简单易学：语法简洁，适合初学者入门
• 平台依赖：主要运行在Windows环境下
• 解释执行：无需编译，代码逐行执行
• 自动化能力强：适合系统管理和任务自动化
• 与COM集成：可以调用各种COM组件扩展功能

VBScript的应用场景

• Windows系统管理脚本
• ASP网页开发
• WSH（Windows Script Host）脚本
• HTML应用程序（HTA）
• 自动化测试脚本

VBScript开发环境搭建

开始VBScript编程之前，需要准备适当的开发环境。

必要工具

1. 文本编辑器：任何纯文本编辑器都可以，如Notepad++、VS Code等
2. Windows Script Host（WSH）：Windows系统自带，无需额外安装
3. Internet Explorer（可选）：用于客户端VBScript开发（已过时）

创建第一个VBScript程序

让我们创建一个简单的”Hello, World!“程序：

' 第一个VBScript程序
MsgBox "Hello, World!"

复制代码

将上述代码保存为hello.vbs文件，然后双击运行，你将看到一个显示”Hello, World!“的消息框。

VBScript基础语法

注释

在VBScript中，有两种注释方式：

' 这是单行注释
REM 这也是单行注释，但较少使用
' 多行注释
' 需要在每行前面
' 添加单引号

复制代码

变量与常量

VBScript使用Dim语句声明变量：

Dim name
Dim age, address, salary ' 一次声明多个变量

复制代码

VBScript是弱类型语言，所有变量都是Variant类型，可以存储任何类型的数据。

name = "John Doe"
age = 30
address = "123 Main Street"
salary = 50000.50

复制代码

• 必须以字母开头
• 不能包含句点(.)
• 不能超过255个字符
• 在作用域内必须唯一

使用Const语句声明常量：

Const PI = 3.14159
Const COMPANY_NAME = "ABC Corporation"

复制代码

数据类型

尽管VBScript中所有变量都是Variant类型，但它可以包含不同种类的子类型：

类型转换函数

VBScript提供了一系列类型转换函数：

Dim strNum, num
strNum = "123"
' 转换为整数
num = CInt(strNum) ' num现在是整数123
' 转换为字符串
Dim numToStr
numToStr = CStr(num) ' numToStr现在是字符串"123"
' 其他转换函数
Dim d, b, dt
d = CDbl("3.14") ' 转换为双精度
b = CBool(1) ' 转换为布尔值True
dt = CDate("2023-11-15") ' 转换为日期

复制代码

运算符

VBScript支持多种运算符：

Dim a, b, result
a = 10
b = 3
result = a + b ' 加法，结果为13
result = a - b ' 减法，结果为7
result = a * b ' 乘法，结果为30
result = a / b ' 除法，结果为3.333...
result = a Mod b ' 取模，结果为1
result = a ^ b ' 指数，结果为1000

复制代码

Dim x, y
x = 10
y = 20
Dim isEqual, isNotEqual, isGreater, isLess
isEqual = (x = y) ' False
isNotEqual = (x <> y) ' True
isGreater = (x > y) ' False
isLess = (x < y) ' True

复制代码

Dim p, q
p = True
q = False
Dim andResult, orResult, notResult
andResult = p And q ' False
orResult = p Or q ' True
notResult = Not p ' False

复制代码

Dim firstName, lastName, fullName
firstName = "John"
lastName = "Doe"
' 使用&运算符连接字符串
fullName = firstName & " " & lastName ' "John Doe"
' 使用+运算符也可以连接字符串，但不推荐
fullName = firstName + " " + lastName ' "John Doe"

复制代码

控制结构

控制结构允许你根据条件执行不同的代码块或重复执行代码。

条件语句

Dim age
age = 18
If age < 18 Then
MsgBox "未成年人"
ElseIf age >= 18 And age < 60 Then
MsgBox "成年人"
Else
MsgBox "老年人"
End If

复制代码

当需要根据多个可能的值执行不同操作时，Select Case语句比多个If…Then…Else语句更清晰：

Dim dayOfWeek
dayOfWeek = 3 ' 假设3代表星期三
Select Case dayOfWeek
Case 1
MsgBox "星期一"
Case 2
MsgBox "星期二"
Case 3
MsgBox "星期三"
Case 4
MsgBox "星期四"
Case 5
MsgBox "星期五"
Case 6, 7 ' 可以使用逗号指定多个值
MsgBox "周末"
Case Else
MsgBox "无效的日期"
End Select

复制代码

循环语句

用于已知次数的循环：

Dim i
For i = 1 To 10
MsgBox "这是第 " & i & " 次循环"
Next
' 使用Step关键字指定步长
For i = 10 To 1 Step -1
MsgBox "倒计时: " & i
Next

复制代码

用于遍历集合或数组中的每个元素：

Dim fruits, fruit
fruits = Array("Apple", "Banana", "Orange")
For Each fruit In fruits
MsgBox "水果: " & fruit
Next

复制代码

用于不确定循环次数的情况：

Dim count
count = 0
' Do While...Loop形式
Do While count < 5
count = count + 1
MsgBox "计数: " & count
Loop
' Do Until...Loop形式
count = 0
Do Until count >= 5
count = count + 1
MsgBox "计数: " & count
Loop
' Do...Loop While形式
count = 0
Do
count = count + 1
MsgBox "计数: " & count
Loop While count < 5
' Do...Loop Until形式
count = 0
Do
count = count + 1
MsgBox "计数: " & count
Loop Until count >= 5

复制代码

这是VBScript中较老的循环结构，现在推荐使用Do…Loop：

Dim count
count = 0
While count < 5
count = count + 1
MsgBox "计数: " & count
Wend

复制代码

退出循环

使用Exit For或Exit Do可以提前退出循环：

Dim i
For i = 1 To 10
If i = 5 Then
Exit For ' 当i等于5时退出循环
End If
MsgBox "i = " & i
Next
Dim count
count = 0
Do While count < 10
count = count + 1
If count = 5 Then
Exit Do ' 当count等于5时退出循环
End If
MsgBox "count = " & count
Loop

复制代码

过程与函数

VBScript允许你将代码组织为可重用的过程和函数。

Sub过程

Sub过程是执行一系列操作但不返回值的代码块：

' 定义一个Sub过程
Sub ShowMessage(message)
MsgBox message
End Sub
' 调用Sub过程
ShowMessage "Hello from Sub procedure!"

复制代码

Function函数

Function函数执行操作并返回一个值：

' 定义一个Function函数
Function AddNumbers(a, b)
AddNumbers = a + b ' 使用函数名返回值
End Function
' 调用Function函数
Dim result
result = AddNumbers(5, 3)
MsgBox "5 + 3 = " & result ' 显示 "5 + 3 = 8"

复制代码

参数传递

VBScript支持两种参数传递方式：ByVal（按值传递）和ByRef（按引用传递）：

' ByVal示例
Sub ByValExample(ByVal x)
x = x + 10
MsgBox "过程内的x值: " & x
End Sub
' ByRef示例
Sub ByRefExample(ByRef x)
x = x + 10
MsgBox "过程内的x值: " & x
End Sub
Dim num
num = 5
MsgBox "调用ByValExample前的num值: " & num ' 显示5
ByValExample num
MsgBox "调用ByValExample后的num值: " & num ' 仍显示5，因为按值传递不影响原变量
MsgBox "调用ByRefExample前的num值: " & num ' 显示5
ByRefExample num
MsgBox "调用ByRefExample后的num值: " & num ' 显示15，因为按引用传递修改了原变量

复制代码

可选参数

VBScript支持可选参数，使用Optional关键字：

Sub Greet(name, Optional greeting = "Hello")
MsgBox greeting & ", " & name & "!"
End Sub
Greet "John" ' 显示 "Hello, John!"
Greet "Jane", "Hi" ' 显示 "Hi, Jane!"

复制代码

参数数组

使用ParamArray关键字可以接受可变数量的参数：

Function Sum(ParamArray numbers())
Dim total, i
total = 0
For i = LBound(numbers) To UBound(numbers)
total = total + numbers(i)
Next
Sum = total
End Function
MsgBox "1 + 2 + 3 = " & Sum(1, 2, 3) ' 显示 "1 + 2 + 3 = 6"
MsgBox "1 + 2 + 3 + 4 + 5 = " & Sum(1, 2, 3, 4, 5) ' 显示 "1 + 2 + 3 + 4 + 5 = 15"

复制代码

数组

数组是存储多个相同类型值的变量集合。

声明数组

' 声明固定大小的数组
Dim fruits(2) ' 创建一个包含3个元素的数组（索引0、1、2）
fruits(0) = "Apple"
fruits(1) = "Banana"
fruits(2) = "Orange"
' 声明动态数组
Dim dynamicArray()
ReDim dynamicArray(2) ' 初始大小为3
dynamicArray(0) = "A"
dynamicArray(1) = "B"
dynamicArray(2) = "C"
' 使用Preserve关键字调整数组大小并保留现有值
ReDim Preserve dynamicArray(4) ' 现在大小为5，保留原有值
dynamicArray(3) = "D"
dynamicArray(4) = "E"

复制代码

多维数组

' 声明二维数组
Dim matrix(2, 2) ' 3x3的矩阵
matrix(0, 0) = 1
matrix(0, 1) = 2
matrix(0, 2) = 3
matrix(1, 0) = 4
matrix(1, 1) = 5
matrix(1, 2) = 6
matrix(2, 0) = 7
matrix(2, 1) = 8
matrix(2, 2) = 9

复制代码

数组函数

VBScript提供了一些内置函数来处理数组：

Dim arr, i
' Array函数创建数组
arr = Array("A", "B", "C", "D", "E")
' LBound和UBound函数获取数组的下界和上界
MsgBox "数组下界: " & LBound(arr) ' 显示0
MsgBox "数组上界: " & UBound(arr) ' 显示4
' 遍历数组
For i = LBound(arr) To UBound(arr)
MsgBox "arr(" & i & ") = " & arr(i)
Next
' Join函数将数组连接为字符串
Dim str
str = Join(arr, ", ")
MsgBox "连接后的字符串: " & str ' 显示 "A, B, C, D, E"
' Split函数将字符串分割为数组
Dim sentence, words
sentence = "This is a sample sentence"
words = Split(sentence, " ")
MsgBox "分割后的单词数量: " & UBound(words) + 1 ' 显示5

复制代码

动态数组操作

' 动态添加元素到数组
Function AddToArray(arr, element)
Dim newSize
newSize = UBound(arr) + 1
ReDim Preserve arr(newSize)
arr(newSize) = element
AddToArray = arr
End Function
Dim myArray
myArray = Array("A", "B", "C")
myArray = AddToArray(myArray, "D")
' 动态从数组中删除元素
Function RemoveFromArray(arr, index)
Dim i
For i = index To UBound(arr) - 1
arr(i) = arr(i + 1)
Next
ReDim Preserve arr(UBound(arr) - 1)
RemoveFromArray = arr
End Function
myArray = RemoveFromArray(myArray, 1) ' 删除索引1处的元素"B"

复制代码

错误处理

良好的错误处理是编写健壮脚本的关键。

On Error语句

' 基本错误处理
On Error Resume Next ' 发生错误时继续执行下一行代码
Dim result
result = 10 / 0 ' 这会导致除以零错误
If Err.Number <> 0 Then
MsgBox "发生错误: " & Err.Description
Err.Clear ' 清除错误对象
End If
On Error GoTo 0 ' 关闭错误处理

复制代码

结构化错误处理

虽然VBScript没有像其他语言那样的try…catch结构，但可以通过子程序模拟：

Sub SafeDivision(a, b)
On Error Resume Next
Dim result
result = a / b
If Err.Number <> 0 Then
MsgBox "除法错误: " & Err.Description
Err.Clear
Else
MsgBox a & " / " & b & " = " & result
End If
On Error GoTo 0
End Sub
SafeDivision 10, 2 ' 正常执行
SafeDivision 10, 0 ' 显示错误信息

复制代码

自定义错误

你可以使用Err对象的Raise方法生成自定义错误：

Sub ValidateAge(age)
If age < 0 Then
Err.Raise vbObjectError + 1, "ValidateAge", "年龄不能为负数"
ElseIf age > 150 Then
Err.Raise vbObjectError + 2, "ValidateAge", "年龄不能超过150岁"
End If
End Sub
On Error Resume Next
ValidateAge -5
If Err.Number <> 0 Then
MsgBox "错误 #" & Err.Number & ": " & Err.Description
Err.Clear
End If
On Error GoTo 0

复制代码

文件系统操作

VBScript可以通过FileSystemObject对象进行文件系统操作。

创建FileSystemObject

Dim fso
Set fso = CreateObject("Scripting.FileSystemObject")

复制代码

文件操作

Dim fso, file
Set fso = CreateObject("Scripting.FileSystemObject")
' 创建文本文件并写入内容
Set file = fso.CreateTextFile("C:\Temp\test.txt", True) ' True表示覆盖已存在的文件
file.WriteLine "这是第一行"
file.WriteLine "这是第二行"
file.Write "这是第三行，没有换行"
file.Close
' 追加内容到文件
If fso.FileExists("C:\Temp\test.txt") Then
Set file = fso.OpenTextFile("C:\Temp\test.txt", 8) ' 8表示追加模式
file.WriteLine vbCrLf & "这是追加的内容"
file.Close
End If

复制代码

Dim fso, file, content
Set fso = CreateObject("Scripting.FileSystemObject")
' 检查文件是否存在
If fso.FileExists("C:\Temp\test.txt") Then
' 读取整个文件
Set file = fso.OpenTextFile("C:\Temp\test.txt", 1) ' 1表示只读模式
content = file.ReadAll
file.Close
MsgBox "文件内容:" & vbCrLf & content
' 逐行读取文件
Set file = fso.OpenTextFile("C:\Temp\test.txt", 1)
content = ""
Do Until file.AtEndOfStream
content = content & file.ReadLine & vbCrLf
Loop
file.Close
MsgBox "逐行读取的文件内容:" & vbCrLf & content
End If

复制代码

Dim fso
Set fso = CreateObject("Scripting.FileSystemObject")
' 创建文件夹
If Not fso.FolderExists("C:\Temp\TestFolder") Then
fso.CreateFolder "C:\Temp\TestFolder"
MsgBox "文件夹已创建"
End If
' 复制文件
If fso.FileExists("C:\Temp\test.txt") Then
fso.CopyFile "C:\Temp\test.txt", "C:\Temp\TestFolder\test_copy.txt"
MsgBox "文件已复制"
End If
' 移动文件
If fso.FileExists("C:\Temp\TestFolder\test_copy.txt") Then
fso.MoveFile "C:\Temp\TestFolder\test_copy.txt", "C:\Temp\TestFolder\test_moved.txt"
MsgBox "文件已移动"
End If
' 删除文件
If fso.FileExists("C:\Temp\TestFolder\test_moved.txt") Then
fso.DeleteFile "C:\Temp\TestFolder\test_moved.txt"
MsgBox "文件已删除"
End If
' 删除文件夹
If fso.FolderExists("C:\Temp\TestFolder") Then
fso.DeleteFolder "C:\Temp\TestFolder"
MsgBox "文件夹已删除"
End If

复制代码

Dim fso, file, folder, fileInfo
Set fso = CreateObject("Scripting.FileSystemObject")
' 获取文件信息
If fso.FileExists("C:\Temp\test.txt") Then
Set file = fso.GetFile("C:\Temp\test.txt")
fileInfo = "文件名: " & file.Name & vbCrLf
fileInfo = fileInfo & "路径: " & file.Path & vbCrLf
fileInfo = fileInfo & "大小: " & file.Size & " 字节" & vbCrLf
fileInfo = fileInfo & "创建日期: " & file.DateCreated & vbCrLf
fileInfo = fileInfo & "最后修改日期: " & file.DateLastModified & vbCrLf
fileInfo = fileInfo & "最后访问日期: " & file.DateLastAccessed
MsgBox fileInfo
End If
' 获取文件夹信息
If fso.FolderExists("C:\Temp") Then
Set folder = fso.GetFolder("C:\Temp")
fileInfo = "文件夹名: " & folder.Name & vbCrLf
fileInfo = fileInfo & "路径: " & folder.Path & vbCrLf
fileInfo = fileInfo & "大小: " & folder.Size & " 字节" & vbCrLf
fileInfo = fileInfo & "创建日期: " & folder.DateCreated & vbCrLf
fileInfo = fileInfo & "包含文件数: " & folder.Files.Count & vbCrLf
fileInfo = fileInfo & "包含子文件夹数: " & folder.SubFolders.Count
MsgBox fileInfo
End If

复制代码

Dim fso, folder, file, subfolder, fileList
Set fso = CreateObject("Scripting.FileSystemObject")
' 遍历文件夹中的文件
If fso.FolderExists("C:\Temp") Then
Set folder = fso.GetFolder("C:\Temp")
fileList = "文件夹 " & folder.Path & " 中的文件:" & vbCrLf & vbCrLf
For Each file In folder.Files
fileList = fileList & file.Name & " (" & file.Size & " 字节)" & vbCrLf
Next
MsgBox fileList
End If
' 递归遍历所有子文件夹
Sub ListAllFolders(folderPath)
Dim fso, folder, subfolder, file
Set fso = CreateObject("Scripting.FileSystemObject")
If fso.FolderExists(folderPath) Then
Set folder = fso.GetFolder(folderPath)
' 列出当前文件夹中的文件
For Each file In folder.Files
WScript.Echo folderPath & "" & file.Name
Next
' 递归处理子文件夹
For Each subfolder In folder.SubFolders
ListAllFolders subfolder.Path
Next
End If
End Sub
' 调用递归函数
ListAllFolders "C:\Temp"

Windows系统交互

VBScript可以与Windows系统进行深度交互，执行各种管理任务。

WScript和CScript

VBScript可以通过WSH（Windows Script Host）运行，有两种宿主程序：

• WScript.exe：Windows应用程序，用于图形界面环境
• CScript.exe：控制台应用程序，用于命令行环境

' 检测当前运行的宿主程序
If InStr(1, WScript.FullName, "cscript.exe", vbTextCompare) > 0 Then
WScript.Echo "运行在CScript下"
Else
MsgBox "运行在WScript下"
End If

复制代码

系统信息获取

' 获取计算机名和用户名
Dim wshNetwork
Set wshNetwork = CreateObject("WScript.Network")
MsgBox "计算机名: " & wshNetwork.ComputerName & vbCrLf & _
"用户名: " & wshNetwork.UserName & vbCrLf & _
"用户域: " & wshNetwork.UserDomain
' 获取环境变量
Dim wshShell
Set wshShell = CreateObject("WScript.Shell")
MsgBox "系统目录: " & wshShell.ExpandEnvironmentStrings("%WINDIR%") & vbCrLf & _
"临时目录: " & wshShell.ExpandEnvironmentStrings("%TEMP%") & vbCrLf & _
"程序文件目录: " & wshShell.ExpandEnvironmentStrings("%ProgramFiles%")

复制代码

注册表操作

Dim wshShell
Set wshShell = CreateObject("WScript.Shell")
' 读取注册表值
On Error Resume Next
Dim ieVersion
ieVersion = wshShell.RegRead("HKLM\SOFTWARE\Microsoft\Internet Explorer\Version")
If Err.Number <> 0 Then
MsgBox "无法读取IE版本: " & Err.Description
Err.Clear
Else
MsgBox "Internet Explorer版本: " & ieVersion
End If
' 写入注册表值
' 注意：写入注册表需要管理员权限
wshShell.RegWrite "HKCU\Software\MyApp\Setting1", "Test Value", "REG_SZ"
wshShell.RegWrite "HKCU\Software\MyApp\Setting2", 123, "REG_DWORD"
' 删除注册表值
wshShell.RegDelete "HKCU\Software\MyApp\Setting1"
wshShell.RegDelete "HKCU\Software\MyApp\Setting2"
wshShell.RegDelete "HKCU\Software\MyApp" ' 删除整个键

VBScript可以通过ADO（ActiveX Data Objects）连接和操作数据库。

连接数据库

' 连接到Access数据库
Sub ConnectToAccess()
Dim conn, connStr
' 创建连接对象
Set conn = CreateObject("ADODB.Connection")
' 连接字符串
connStr = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\Temp\MyDatabase.accdb;"
' 打开连接
conn.Open connStr
MsgBox "成功连接到Access数据库"
' 关闭连接
conn.Close
Set conn = Nothing
End Sub
' 连接到SQL Server数据库
Sub ConnectToSQLServer()
Dim conn, connStr
' 创建连接对象
Set conn = CreateObject("ADODB.Connection")
' 连接字符串
connStr = "Provider=SQLOLEDB;Data Source=SERVER_NAME;Initial Catalog=DATABASE_NAME;User ID=USERNAME;Password=PASSWORD;"
' 打开连接
conn.Open connStr
MsgBox "成功连接到SQL Server数据库"
' 关闭连接
conn.Close
Set conn = Nothing
End Sub

执行SQL查询

' 执行查询并获取结果
Sub ExecuteQuery()
Dim conn, connStr, rs, sql
' 创建连接对象
Set conn = CreateObject("ADODB.Connection")
' 连接字符串（以Access为例）
connStr = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\Temp\MyDatabase.accdb;"
' 打开连接
conn.Open connStr
' 创建记录集对象
Set rs = CreateObject("ADODB.Recordset")
' SQL查询语句
sql = "SELECT * FROM Customers"
' 执行查询
rs.Open sql, conn
' 处理结果
Dim result
result = "查询结果:" & vbCrLf & vbCrLf
' 显示列名
Dim i
For i = 0 To rs.Fields.Count - 1
result = result & rs.Fields(i).Name & vbTab
Next
result = result & vbCrLf
' 显示数据
Do Until rs.EOF
For i = 0 To rs.Fields.Count - 1
result = result & rs.Fields(i).Value & vbTab
Next
result = result & vbCrLf
rs.MoveNext
Loop
MsgBox result
' 关闭记录集和连接
rs.Close
conn.Close
Set rs = Nothing
Set conn = Nothing
End Sub

复制代码

执行更新操作

' 执行插入、更新和删除操作
Sub ExecuteUpdate()
Dim conn, connStr, sql
' 创建连接对象
Set conn = CreateObject("ADODB.Connection")
' 连接字符串（以Access为例）
connStr = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\Temp\MyDatabase.accdb;"
' 打开连接
conn.Open connStr
' 插入记录
sql = "INSERT INTO Customers (CustomerName, ContactName, Country) VALUES ('Test Customer', 'John Doe', 'USA')"
conn.Execute sql
MsgBox "已插入新记录"
' 更新记录
sql = "UPDATE Customers SET ContactName = 'Jane Doe' WHERE CustomerName = 'Test Customer'"
conn.Execute sql
MsgBox "已更新记录"
' 删除记录
sql = "DELETE FROM Customers WHERE CustomerName = 'Test Customer'"
conn.Execute sql
MsgBox "已删除记录"
' 关闭连接
conn.Close
Set conn = Nothing
End Sub

使用参数化查询

' 使用参数化查询防止SQL注入
Sub ParameterizedQuery()
Dim conn, connStr, cmd, param
' 创建连接对象
Set conn = CreateObject("ADODB.Connection")
' 连接字符串（以Access为例）
connStr = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\Temp\MyDatabase.accdb;"
' 打开连接
conn.Open connStr
' 创建命令对象
Set cmd = CreateObject("ADODB.Command")
cmd.ActiveConnection = conn
' 设置SQL语句
cmd.CommandText = "SELECT * FROM Customers WHERE Country = ?"
' 创建参数
Set param = cmd.CreateParameter("Country", 200, 1, 50, "USA") ' 200表示adVarChar，1表示adParamInput
cmd.Parameters.Append param
' 执行查询
Dim rs
Set rs = cmd.Execute
' 处理结果
Dim result
result = "查询结果:" & vbCrLf & vbCrLf
' 显示列名
Dim i
For i = 0 To rs.Fields.Count - 1
result = result & rs.Fields(i).Name & vbTab
Next
result = result & vbCrLf
' 显示数据
Do Until rs.EOF
For i = 0 To rs.Fields.Count - 1
result = result & rs.Fields(i).Value & vbTab
Next
result = result & vbCrLf
rs.MoveNext
Loop
MsgBox result
' 关闭记录集和连接
rs.Close
conn.Close
Set rs = Nothing
Set cmd = Nothing
Set conn = Nothing
