在32位或64位Excel VBA上使用Windows SHBrowseForFolder函数可以实现选择文件夹的功能。以下是完善且全面的答案:
Windows SHBrowseForFolder函数是一个Windows API函数,用于显示一个对话框,允许用户选择文件夹。该函数需要通过VBA的Declare语句进行声明和调用。具体步骤如下:
#If VBA7 Then
Private Declare PtrSafe Function SHBrowseForFolder Lib "shell32.dll" Alias "SHBrowseForFolderA" (lpBrowseInfo As BrowseInfo) As LongPtr
Private Declare PtrSafe Function SHGetPathFromIDList Lib "shell32.dll" Alias "SHGetPathFromIDListA" (ByVal pidList As LongPtr, ByVal lpBuffer As String) As LongPtr
#Else
Private Declare Function SHBrowseForFolder Lib "shell32.dll" Alias "SHBrowseForFolderA" (lpBrowseInfo As BrowseInfo) As Long
Private Declare Function SHGetPathFromIDList Lib "shell32.dll" Alias "SHGetPathFromIDListA" (ByVal pidList As Long, ByVal lpBuffer As String) As Long
#End If
Private Type BrowseInfo
hWndOwner As Long
pIDLRoot As Long
pszDisplayName As String
lpszTitle As String
ulFlags As Long
lpfnCallback As Long
lParam As Long
iImage As Long
End Type
Function SelectFolder() As String
Dim bi As BrowseInfo
Dim pathBuffer As String
Dim pidl As LongPtr
' 设置对话框的属性
With bi
.hWndOwner = 0 ' 设置为0表示使用Excel窗口作为父窗口
.lpszTitle = "请选择文件夹" ' 对话框标题
.ulFlags = &H1 ' 显示"新建文件夹"按钮
End With
' 调用SHBrowseForFolder函数显示对话框
pidl = SHBrowseForFolder(bi)
' 获取所选文件夹的路径
pathBuffer = Space$(MAX_PATH)
SHGetPathFromIDList pidl, pathBuffer
' 返回文件夹路径
SelectFolder = Left$(pathBuffer, InStr(pathBuffer, Chr(0)) - 1)
End Function
Sub TestSelectFolder()
Dim folderPath As String
folderPath = SelectFolder()
' 打印所选文件夹路径
MsgBox folderPath
End Sub
通过以上步骤,您可以在32位或64位Excel VBA上使用Windows SHBrowseForFolder函数实现文件夹选择功能。
