Faxing from ASP.NET

[David Lozzi]

Howdy,

I'm trying to send faxes from my asp.net code. I'm getting a "server threw
exception". Real helpful. here's my code


Dim FXServ As New FAXCOMLib.FaxServer
Dim FXDoc As FAXCOMLib.FaxDoc
Dim iFaxJob As Integer

'FXServ.Connect("SERVER")

FXDoc = CType(FXServ.CreateDocument("c:\test.txt"),
FAXCOMLib.FaxDoc)

FXDoc.FileName = "c:\test.txt"
FXDoc.FaxNumber = "15551231234"

iFaxJob = FXDoc.Send()

FXServ.Disconnect()


And here's the error


The server threw an exception.
Description: An unhandled exception occurred during the execution of the
current web request. Please review the stack trace for more information
about the error and where it originated in the code.

Exception Details: System.Runtime.InteropServices.COMException: The server

Hard to tell what it is without the COM component, but you might want to see
if you need to use

<%@ Page AspCompat="true" Language="C#" %>

"The AspCompat attribute forces the page to execute in STA mode. The runtime
throws an exception if the compatibility tag is omitted and an STA component
is referenced on the page. If you convert the STA component to an assembly
using Tlbimp.exe, the runtime does not detect that the component uses the
STA model and does not throw an exception, but your application can suffer
from poor performance.

Important
COM components that are created at construction time run before the request
is scheduled to the STA thread pool and consequently run on a multithreaded
apartment (MTA) thread. This has a substantial negative performance impact
and should be avoided. If you use AspCompat with STA components, you should
create COM components only from the Page_Load event or later in the
execution chain and not at page construction time. "
