Finally, we introduce the code to create a file selection list, where you use the built-in FileSystem object to get information about files and folders.
For simplicity, the routine assumes that the spreadsheet file and the ASP file are in the same directory. Get the current directory name by Vserverfolder= Server.MapPath (".") and convert it to a folder object to find the files in the directory.
The. GetFolder method for filesystem objects is used as follows:
Set oFs = Server.CreateObject ("Scripting.FileSystemObject")
Set ofolder = Ofs.getfolder (Vserverfolder)
By enumerating the. Files Collection of the Folder object, you can get the files under the folders and limit the file types displayed to Excel. Execute the following html/asp code to create a file selection list:
< select Name= "Xlbook" >
Voptions = ""
For each ofile in Ofolder.files
If ofile.type = "Microsoft Excel Worksheet" Then
Voptions = voptions & "< option >" & _
Server.HTMLEncode (ofile.name) & "</option >
