Hi Brian,

From your description, you got some certain error when uploading "exe" file
using the HtmlInputFile control in asp.net web application ,yes?

As far as I know, there is no buildin checking on the uploading file's type
in asp.net and generally we need to provide our checking code, such as
client validaiton script code, here is a tech article which has mentioned
this:

and as for the error you get, would you provide some detailed information
on it ? Thanks.
