VBScript文件或文件夹选择

Question

VBScript文件或文件夹选择

6

我有一个包含几个vbs代码的小型hta文件。它可以选择文件夹或文件并将其复制到固定位置。

<html>
<head>
<Title>File Copy </Title>
<style>
img.exco
{
position:absolute;
bottom:10px;
right:10px
}
</style>
<!--Put this sub here to avoid resize flickering.-->
<script language = "VBScript">
 sub DoResize
    'resize   
    window.resizeTo 690,350
    screenWidth = Document.ParentWindow.Screen.AvailWidth
    screenHeight = Document.ParentWindow.Screen.AvailHeight
    posLeft = (screenWidth - 700) / 2
    posTop = (screenHeight - 430) / 2     
    'move to centerscreen
    window.moveTo posLeft, posTop

  end sub

DoResize()
</script>

我在点击第一个按钮时，选择项目（文件夹或文件）遇到了问题。

它可以很好地选择文件夹，但是在选择文件时，我收到了“第60行未指定的错误”，请帮助我解决问题。我希望文件浏览器窗口保持现在的样子，有“确定”按钮，而不是“打开”按钮，这样我就可以选择文件夹或文件。
此外，文件浏览器没有从我设置的位置启动。如何解决？

你传入了strStartDir参数，但没有使用它，这就是为什么它不会在指定的位置打开。将&h4000替换为你的strStartDir即可打开该位置。另外，不要使用use count到第60行，你应该已经知道这是哪一行了，所以请指出它。 - Sorceri

之前尝试过，结果出现了“行：60 错误：类型不匹配：'shell.BrowseForFolde”... 我找不到一种方法来在同一个对话框窗口中选择文件夹和文件。 - Root Loop

我可以重现这个错误，似乎是在BrowseForFolder()对话框中选择文件而不是文件夹时发生的。不确定如何修复它（甚至是否可以完全修复）。要传递根路径，必须将其添加为最后一个参数，即在&H400之后。 - Tomalak

还有没有一种方法可以指定文件类型？比方说，如果我只想看到.rtm文件（如果存在的话）？ - Root Loop

有什么建议可以在同一个窗口中选择文件夹或文件吗？ - Root Loop

这是设置起始目录和选择文件的示例。

Const GeneratedItemFlag = &h4000

dim shellApp 
dim folderBrowseDialog
dim filePath
set shellApp = CreateObject("Shell.Application")

set folderBrowseDialog = shellApp.BrowseForFolder(0,"Select the file", GeneratedItemFlag, "c:\")


if folderBrowseDialog is nothing then
    msgbox "No file was selected.  This will now terminate."
    Wscript.Quit
else
    filePath= folderBrowseDialog.self.path
end if

谢谢，但这个仍然出现了相同的错误。我在考虑可能是文件类型或扩展名的原因？因为当我使用您的代码或我的代码来选取一些常见的文件类型，如PDF文件或文本文件时，根本没有错误，但如果我选择一些特殊的文件类型，如“.rms或.rtm”，就会出现错误。 - Root Loop

实际上，第一个代码示例中的HTA部分存在一个错误，这将在以后会导致一些问题。标签写成了NAVIGATABLE="no"。它应该是NAVIGABLE="no"。你需要去掉AT。

如何在同一窗口中选择文件或文件夹？根据 MSDN，Shell.BrowseForFolder方法创建一个对话框，使用户能够选择一个文件夹，然后返回所选文件夹的Folder对象。

因此，要浏览文件，我们需要使用另一种方法。存在本地的<input ...>标签与type="file"属性。然而，使用它带来的缺点比优点更多（请参见下面的第2个解决方案）。

在下一个解决方案中，通过使用HtmlDlgHelper对象 - 一个鲜为人知且文档质量较差的对象，可以实现浏览文件。与上述<input ...>标签相比，这个解决方案提供了定义初始位置和文件类型掩码的功能。

<HTML>
<HEAD>
<Title>File/Folder Copy B</Title>
<!-- Browse for 
      - file:   based on the HTMLDlgHelper class 
                registered via C:\Windows\System32\mshtmled.dll
                (.OpenFileDlg returns string)
      - folder: based on the Shell.BrowseForFolder method
                (returns the selected folder's Folder object)
