VBA压缩与解压缩源码

Access 2022-04-18 22:08:29

VBA本身没有压缩和解压缩的函数,但可调用zip.dll  unzip.dll 或 winrar.exe 命令行方式来实现对文件的压缩与解压缩


 

1、批量解压缩(一次性解压指定文件夹中所有rar文件)
 

Sub UnRarFile()   '解压缩程序  Dim Rarexe As String  Dim RAR As String  Dim Myadd As String  Dim FileString As String  Dim Result As Long    Rarexe = "C:\program files\winrar\winrar.exe" 'rar程序路径    myRAR = "D:\工资表\*.rar"  '需要解压缩的rar文件,用通配符可以解压所有文件    Myadd = "D:\工资表"     ' 解压后的文件存放路径    FileString = Rarexe & " X " & myRAR & " " & Myadd 'rar程序的X命令,用来解压缩文件的字符串    Result = Shell(FileString, vbHide) '执行解压缩End Sub


运行效果: 把D盘的工资表文件夹中的所有压缩文件一次性解压。

2、批量压缩文件(一次性压缩指定文件夹中所有xls文件)
   

Sub RarFile()   '压缩程序  Dim Rarexe As String  Dim myRAR As String  Dim Myfile As String  Dim FileString As String  Dim Result As Long    Rarexe = "C:\program files\winrar\winrar.exe" 'rar程序路径    myRAR = "D:\工资表\工资表.rar"  '压缩后的文件名    Myfile = "D:\工资表\*.xls"    ' 指定要压缩的文件    FileString = Rarexe & " A " & myRAR & " " & Myfile 'rar程序的A命令压缩文件的字符串    Result = Shell(FileString, vbHide) '执行压缩End Sub

Set oba = CreateObject("Wscript.shell")'[压缩]oba.Run "winrar a c:\test.rar c:\*.txt",0,True'[解压缩]oba.Run "winrar x -o+ C:\test.rar *.txt C:\test",0,TrueSet oba = Nothing
