I have a small hta file with few vbs codes. It selects folder or file then make a copy to a fixed location.

<head>
<Title>File Copy </Title>
<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

I have problems with selecting items (folder or file) when I click the first button.

It picks up folder well but when selecting files, I got "unspecified error on line 60", please help me to troubleshoot. I want the file browser window like the way it is now with OK button on it, not a "open" button, so I can select both folder or file.
Also the file browser does not start up from the location I setup. How to fix it?

How to select folder or file in the same window? By MSDN, The Shell.BrowseForFolder method creates a dialog box that enables the user to select a folder and then returns the selected folder's Folder object.

Thus, for browse for a file we need to use another method. There exists the native <input ...> tag with type="file" attribute. However, using it brings more cons than pros (see 2nd solution below).

In next solution, the Browse for File is achieved by using the HtmlDlgHelper object - an obscure and poorly documented object that is nevertheless available on all Windows systems... In comparison with <input ...> tag mentioned above, this solution offers to define both initial location and file type masking.

<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)

Here is an example of setting the start directory and the selection of files.

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

There is actually an error in the HTA portion of the first code example that will cause some problems down the road. The tag says NAVIGATABLE="no". It should be NAVIGABLE="no". You need to lose the AT.
