Error Uploading file to Server [RESOLVED]

**EyeTalion** · Dec 5th, 2002, 03:08 PM

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:

Code:

<%@ 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
		</Script>

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?

**EyeTalion** · Dec 9th, 2002, 03:31 PM

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