VBA返回相应的路径信息，对于在Excel中使用编程来处理数据，极其重要。
下面，为你介绍与返回路径相关的各种代码与函数。
①返回应用程序完整路径
Application.Path
比如：D:\SoftWare\Office2003\OFFICE11
②返回当前工作薄的路径
ThisWorkbook.Path
比如：D:
③返回当前默认文件路径
Application.DefaultFilePath
比如：C:\Documents and Settings\Administrator\My Documents
④只返回路径
Application.ActiveWorkbook.Path
比如：D:
⑤返回路径及工作簿文件名
Application.ActiveWorkbook.FullName
比如：D:\Book1.xls
⑥返回工作簿文件名
Application.ActiveWorkbook.Name
比如：Book1.xls
上面的六种情况，在VBA环境下，你也可以通过如下的代码测试：
MsgBox Application.Path
ActiveSheet.Cells(1, 1).Value = Application.Path
MsgBox ThisWorkbook.Path
ActiveSheet.Cells(2, 1).Value = ThisWorkbook.Path
MsgBox Application.DefaultFilePath
ActiveSheet.Cells(3, 1).Value = Application.DefaultFilePath
MsgBox Application.ActiveWorkbook.Path
ActiveSheet.Cells(4, 1).Value = Application.ActiveWorkbook.Path
MsgBox Application.ActiveWorkbook.FullName
ActiveSheet.Cells(5, 1).Value = Application.ActiveWorkbook.FullName
MsgBox Application.ActiveWorkbook.Name
ActiveSheet.Cells(6, 1).Value = Application.ActiveWorkbook.Name
除此之外，和路径有关的一个函数Dir，是专门用来判断文件是否存在的函数，代码如下：
Application.ScreenUpdating = False
With Application.FileSearch
.FileType = msoFileTypeExcelWorkbooks
.LookIn = ThisWorkbook.Path
.SearchSubFolders = True
.Execute
If .Execute() > 0 Then
m = .FoundFiles.Count '当前目录及子目录所有工作薄总数
'MsgBox m
For Each f In .FoundFiles '在所有的工作薄里做一个循环
'MsgBox Dir(f) '列出每个工作薄的名称，只显示名称，如 dzwebs.xls ，无路径
If (Dir(f) <> "Total.xls") Then
Set xlsApp = New Excel.Application
Set xlsBook = Workbooks.Open(ThisWorkbook.Path & "\" & Dir(f))
Set MyWantGetsheet = xlsBook.Worksheets(1)
For i = 1 To 8
MyWantGetsheet.Cells(i, 6).Value = "www.dzwebs.net"
Next i
xlsBook.Save
xlsBook.Close
xlsApp.Quit
Set xlsApp = Nothing
Set xlsBook = Nothing
Set MyWantGetsheet = Nothing
Application.ScreenUpdating = True
End If
Next
End If
