More information

Internet Explorer displays the File Download dialog box when the protocol handler uses the IInternetProtocolSink::ReportProgress method to send a BINDSTATUS_CONTENTDISPOSITIONATTACH notification to the transaction handler. To suppress this dialog box, do not send the content disposition notification.

NOTE: This does not suppress the File Download dialog box when you run a hyperlink URL that ends with a file extension that Internet Explorer considers unsafe. For additional information, click the article number below to view the article in the Microsoft Knowledge Base:
