Anyone know why I'm getting this error when I try to upload?

"Object reference not set to an instance of an object."

<input id="pdfUpload"
<FORM id="_ctl0" encType="multipart/form-data" runat="server">

If Not pdfUpload.PostedFile Is Nothing Then
If pdfUpload.PostedFile.FileName.Trim().Length > 0 And _
pdfUpload.PostedFile.ContentLength > 0 Then
Const strBaseDir As String = "C:\PBSS_Uploads\"
Dim strFilename As String = _
Path.GetFileName(pdfUpload.PostedFile.FileName)

pdfUpload.PostedFile.SaveAs(strBaseDir & strFilename)

End If
End If

Could you attach the entire source for the upload component including the ASPX part?

Thanks

I created another asp.net project and I only placed a button and <input> tag on the page. I still get the same error.

"Object reference not set to an instance of an object."

Here's the entire program:


<%@ Page Language="vb" AutoEventWireup="false" Codebehind="WebForm1.aspx.vb" Inherits="fileUpload.WebForm1"%>
<%@ Import Namespace="System.IO" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML>
<HEAD>
<title>WebForm1</title>
<Script language="vb" runat="server">
Sub UploadTime(sender as object, e as eventArgs)
'PDF Upload
If Not pdfUpload.PostedFile Is Nothing Then
If pdfUpload.PostedFile.FileName.Trim().Length > 0 And _
pdfUpload.PostedFile.ContentLength > 0 Then
Const strBaseDir As String = "C:\PBSS_Uploads\"
Dim strFilename As String = _
Path.GetFileName(pdfUpload.PostedFile.FileName)

pdfUpload.PostedFile.SaveAs(strBaseDir & strFilename)

End If
End If
End Sub

Looks like your input box needs runat="server" (the pdfUpload box)

thanks rat, that was it.

Do you know how to filter out the common dialog box, so only .pdf extensions show?

let me rephrase this, can you filter out file entensions in ASP.NET like you can in VB?
