I frequently get the following error when using EO Web Dynamic Download. It woeks OK on my development machine under localHost but fails when deployed to my production server.
Other EO web controls work fine, and the temparary folder I use (Server.MapPath("~/PCS_Data/_downloads") is accessed OK by other functions in my web app.
What am I doing wrong?

I create a fille with a textwriter and close it.
My code says
Quote:

Dim args As New NameValueCollection()
args("fn") = tempFIle
e.DynamicDownload(GetType(FileContentGenerator), args) 'e is EO.Web.DownloadEventArgs

Then
Private Class FileContentGenerator
Inherits EO.Web.DynamicDownloadContent

Protected Overrides Sub GenerateContent()
SetFileName(Path.GetFileName(Me.Arguments("fn")), -1)
Dim buffer As Byte() = ReadAllBytes(Me.Arguments("fn"))
Write(buffer, 0, buffer.Length)
File.Delete(Me.Arguments("fn"))
End Sub
End Class

On the web form I have

<eo:Downloader ID="Downloader" runat="server" AutoHideDownloadButton="False" DownloadButtonID="cmdDownload" DynamicContent="true"></eo:Downloader>



The error I get is
Code:

Hi,

We won't be able to tell you why your code can not find this file --- this is your own code trying to read a file and .NET reports that the file does not exist. You will have to troubleshoot these kind of issues yourself.

Thanks!
Phil
