ASP.Net Open/Save dialog box not saving PDF documents correctly.
I am using ASP.Net Open/Save dialog box not saving PDF documents correctly. The file acts like it's being saved but the size is only 1KB and the orignal file size is 10KB.
This is my code:
Dim root As String = "C:\"
Dim filepath As String = Request.Params("file")
If Not filepath Is Nothing Then
If File.Exists(filepath) Then
Dim filename As String = Path.GetFileName(filepath)
Dim newFile = root + filename
Response.Clear()
Response.ContentType = "application/pdf"
Response.AddHeader("Conten
"attachment; filename=""" & filename & """")
' Response.WriteFile(newFile
' Response.Flush()
' Response.End()
End If
End If
I apprecate any help you can give me.

Security Exception
Description: The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file.
Exception Details: System.Security.SecurityEx
I am setup as an IIS server. So, I am not sure how to download to my hard drive.
Any suggestions? Thanks for the help so far.

I tried it from another computer that is not setup as a server and got the same error message.
hi, this makes sense, if you are trying to access a file outsite the app domain (eg virtual directory) then it will throw an error - try and right click the folder and give the asp.net user on the pc permissions to the folder...

Hi deanvanrooyen,
Under the Secuity tab of the directory I have added all abilities to all the Users. Under the web sharing tab I have made the directory sharable. The general tab still has readonly checked - even though I uncheck it a serveral times and applied.
Currenty the files are being created but the error message is being stored in them NOT the file data.
Could it be a secuirty issue on the ISP part? I can see the files just fine. I upload them fine and view them with FTP just fine.
I have even tried to change Secuirty Wizard to set FULL access on everything (as dangerous as that was) it did not help. so, I put all the default settings back.
I am at a loss here but I appreciate your help.

Hi deanvanrooyen,
This has become an Emergency. I think I'm going to loose my job if I don't figure this out by tomorrow. Is there anyone you can consult to help us?
The file being created and the error message is being stored in the file.
Please help me.

The ISP is external to my organization - we are very small. I have been working on this problem for soo long everyone is getting impatient with me. :(
I have not been able to get it working on my local dev box because I am trying to access the file from the ISP. On the ISP side I had setup a directory called documents. I have given everyone all permissions. I am able to create new directories under the documents directory and I am able to upload files to the newly created directories. I can verify these files were uploaded correctly by using FTP and viewing them.
I highlighted the directory documents and right click on it. I select the security tab on the documents directory I have the Network_Service, IUSR_4444444 I have given all permissions: Write, Modify, Read, Read and Execute. For Folders, subfolders and files.
My latest code looks like this:
<%@LANGUAGE="VBSCRIPT" CODEPAGE="1252"%>
<%@ IMPORT namespace="System.Data" %>
<%@ IMPORT namespace="System.Web.Http
<%@ Import Namespace="System.IO"%>
<head>
<title>File Download</title>
<script language="VB" runat="server">
Sub Page_Load(sender As Object, e As EventArgs)
Dim filepath As String = Request.Params("file")
If Not filepath Is Nothing Then
If File.Exists(filepath) Then
Dim filename As String = Path.GetFileName(filepath)
Response.Clear()
Response.ContentType = "application/octet-stream;
Response.AddHeader("Conten
Response.Flush()
Response.WriteFile("C:\dow
Response.End()
End If
End If
End Sub
</script>
I am getting a file created in the c:\downloadedDocuments directory but when I view the document it has the permission error.
I have tried to set the all the users to have full access on this directoy on my local machine.
Thank you for trying to help me. If you can give me step by step stuff to check that would be great.

I changed the code to do a File.Copy. File.Copy("C:\\databaseInf
The code calling the File.Copy is located on the ISP server.
I am stilll getting this permisson error:
Server Error in '/' Application.

Description: The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file.

Line 20: ' Response.ContentType = "application/octet-stream;
Any Ideas?

Okay, I think part of my problem is that I am trying to access directories on client side when the code is located on the server and is not JavaScript code.
File.Copy("C:\\databaseInf
How would I access the client's C: directory?
http://localhost/C://databaseInfo.txt??
File.Copy("C:\\databaseInf
How would I access the client's C: directory?
http://localhost/C://databaseInfo.txt??
It's not a good thing to access the clients directory. I doubt there is anything out there apart from ActiveX etc that would let you access the clients file structure from a browser.
You can browse the clients directory using the FileUpload control to choose the file to upload. But if you want to open files from the browser then that's not adviseable vis a browser.

Thank you both for your help. The simple solution: FileWrite parameter is the location of the file being written not the location of where I wanted the file written.
