http://www.aspupload.com/manual_simple.html
says
Upload.Files is a collection of UploadedFile objects which offer access to
various properties and attributes of uploaded files, such as filename, path,
size, hash value, etc. The UploadedFile object also offers many methods
which enable you to manipulate uploaded files (copy, move, save to the
database, delete, etc.) Individual items of the collection can be referenced
via numeric or string indices, or iterated through via the For-Each
statement.

which links to
http://www.aspupload.com/object_file.html
that says
FileName As String (Read-Only)
Returns the saved file's name. It may be different from the original file
name if unique file generation (the property Upload.OverwriteFiles) is in
effect.
Usage:

Response.Write File.FileName

So, if that returns a string, you can just check the characters after the
last . for the extension.

Hi everybody,
I made something thus:

For Each Arquivo in objUpload.Files
Caminho_e_Arquivo = Arquivo.Path
ExtensaoArquivo = InStr(Arquivo.FileName,".gif")
Exit For
Next

If ExtensaoArquivo = 0 then '»»NÃO foi encontrado a extensão .gif
Response.Write "<script language='JavaScript'>alert('Tipo inválido de
arquivo.\nEnvie arquivo GIF'); "
Response.Write "history.go(-1);</script>"
Response.End()
End If

It was not exactly what I wanted, because I really want to check the kind of
mime file:
image/jpg, image/gif, application/msexcel, etc.... Because the user can
change a file extension, but not the mime type!

Anybody knows anything using aspupload or other component???

Thanks,
