We recently migrated applications from one web server to another. Previously they could upload files to the server and if it already existed, it would over write with the new one.
Now I have to manually delete the file from the server so they can upload a new one. If I delete it they can upload a new one and even upload one to overwrite the one they uploaded. But only after I delete the "migrated" one.
All of the security is correct. ASPNET and IIS_WPG have permissions.
Da Code:
If System.IO.File.Exists(UploadLoc + Me.FileUpload_PDF.FileName) Then
System.IO.File.Delete(UploadLoc + Me.FileUpload_PDF.FileName)
End If
Me.FileUpload_PDF.SaveAs(UploadLoc + Me.FileUpload_PDF.FileName)
I get the dreaded "access to the file is denied"
Update: I find if I give "USER" modify rights it works, but that does not seem secure.
