GetTempPath取得的是一个DOS名称,当文件名长度大于8时，长文件名格式“C:\Documents and Settings\Administrator\Local Settings\Temp”会显示成“C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp”的短文件名格式，如何根据自己需要取得系统临时目录的途径，下面是一个新写的函数，调用两个API 实现，相信许多朋友可能用得到。

　　Option Explicit

　　Private Declare Function GetLongPathName Lib "kernel32" Alias "GetLongPathNameA" (ByVal lpszShortPath As String, ByVal lpszLongPath As String, ByVal cchBuffer As Long) As Long

　　Private Declare Function GetTempPath Lib "kernel32" Alias "GetTempPathA" (ByVal nBufferLength As Long, ByVal lpBuffer As String) As Long

　　Sub GetTEMPfolder(Optional ByVal showlong As Boolean = True)

　　Dim longname As String, shortname As String

　　shortname = Space(256)

　　GetTempPath Len(shortname), shortname

　　longname = Space(1024)

　　GetLongPathName shortname, longname, Len(longname)

　　MsgBox "Tempfolder : " & IIf(showlong = True, longname, shortname)

　　End Sub

　　Private Sub Command1_Click()

　　GetTEMPfolder '长文件名

　　GetTEMPfolder False '短文件名

　　End Sub
