本文介绍了一种利用HTML应用程序（HTA）和Windows注册表来实现文件选择的方法，包括两种不同的实现方式：一种是直接通过注册表读取用户选择的文件路径；另一种则是将文件路径写入到临时文本文件中再进行读取。

Rem 选择文件-从注册表中获取
Function SG_BrowseForFileFromReg()
    Dim shell: Set shell = CreateObject("WScript.Shell")
    Dim fso: Set fso = CreateObject("Scripting.FileSystemObject")
    Dim tempFolder: Set tempFolder = fso.GetSpecialFolder(2)
    Dim tempName: tempName = fso.GetTempName()
    Dim tempFile: Set tempFile = tempFolder.CreateTextFile(tempName & ".hta")
    tempFile.Write _
    "<html>" & _
    "<head>" & _
    "<title>Browse</title>" & _
    "</head>" & _
    "<body>" & _
    "<input type='file' id='f' />" & _
    "<script type='text/javascript'>" & _
    "var f = document.getElementById('f');" & _
    "f.click();" & _
    "var shell = new ActiveXObject('WScript.Shell');" & _
    "shell.RegWrite('HKEY_CURRENT_USER\\Volatile Environment\\MsgResp', f.value);" & _
    "window.close();" & _
    "</script>" & _
    "</body>" & _
    "</html>"
    tempFile.Close
    shell.Run tempFolder & "\" & tempName & ".hta", 0, True
    SG_BrowseForFileFromReg = shell.RegRead("HKEY_CURRENT_USER\Volatile Environment\MsgResp")
    shell.RegDelete "HKEY_CURRENT_USER\Volatile Environment\MsgResp"
    fso.DeleteFile tempName & ".hta"
End Function

Rem 选择文件-从临时文件中获取
Function SG_BrowseForFileFromTxt()
    Dim shell: Set shell = CreateObject("WScript.Shell")
    Dim fso: Set fso = CreateObject("Scripting.FileSystemObject")
    Dim tempFolder: Set tempFolder = fso.GetSpecialFolder(2)
    Dim tempName: tempName = fso.GetTempName()
    Dim tempFile: Set tempFile = tempFolder.CreateTextFile(tempName & ".hta")
    Dim tempBaseName: tempBaseName = tempFolder & "\" & tempName
    
    Rem 写HTML应用程序（hta）
    tempFile.Write _
    "<html><head><meta charset='UTF-8' /><title>Browse</title></head>" & _
    "<body><input type='file' id='f'>" & _
    "<script type='text/javascript'>" & _
    " var f = document.getElementById('f');f.click();" & _
    " var fso = new ActiveXObject('Scripting.FileSystemObject');" & _
    " var file = fso.OpenTextFile('" & _
    Replace(tempBaseName, "\", "\\") & ".txt" & "', 2, true, -1);" & _
    " file.Write(' ' + f.value + ' '); file.Close(); window.close();" & _
    "</script></body></html>"
    
    tempFile.Close
    shell.Run tempBaseName & ".hta", 1, True
    
    Set tempFile = fso.OpenTextFile(tempBaseName & ".txt", 1, False, -1)
    SG_BrowseForFileFromTxt = Trim(tempFile.ReadLine)
    tempFile.Close
    
    Rem 删除创建的临时文件
    fso.DeleteFile tempBaseName & ".hta"
    fso.DeleteFile tempBaseName & ".txt"
End Function
