Maintaining filenames of files dropped into a richtext control...

I have been researching a way to override the file drop behavior into a richtext control in my Windows forms application.

For some file types (Excel, Word, PDF, etc) a object link appears with an icon which is the desired affect. What I don't desire is the attachment (or file) being renamed to its object type (ie. spreadsheet.xlsx is being added as "Microsoft Excel Worksheet" for example). I have verified the "FileDrop", "Filename" and "FilenameW" datatypes do in fact carry the name of the file being drop into the RichText control. I have even tried manually adding them.

Any insight into addressing this problem (if possible) would be appreciated.

Thanks

PS. CSV, TXT file types seem to work fine.

What I have tried:

Dim ofd As OpenFileDialog = New OpenFileDialog
ofd.Multiselect = True
ofd.Filter = "All Files (*.*)|"

If ofd.ShowDialog(Me) = System.Windows.Forms.DialogResult.OK Then

   Dim fileNames As Specialized.StringCollection = New Specialized.StringCollection()
   fileNames.AddRange(ofd.FileNames)
   Clipboard.SetFileDropList(fileNames)
   rtbAdditionalInfo.Paste()

End If

ofd.Dispose()
