Author ASP.net strange object error
Do

Hi,

I get this error, "Object reference not set to an instance of an object."
when I set the properties

to a label. However, when I response.write them all out, they work just
fine.

Any ideas?

Do

Try

'Display the repeater template with the link enabled

Dim objDoc As New document

dtgDocument.DataSource =
objDoc.getdocuments(Request.QueryString("filename"), , )

dtgDocument.DataBind()

objDoc = Nothing

Try

'Run document security check

Dim objDocUser As New user

Dim objFileProps As New PropertyReaderClass

Dim objPropReader As DocumentProperties

GC.Collect()

Dim strFolder As String

strFolder = Server.MapPath("../files/")

objPropReader = objFileProps. GetDocumentProperties(strFolde
r &
Request.QueryString("filename"))
