(Faxman 4.4.4.0 - .NET controls)

I am finding that if I queue about 20 faxes in Faxman and then have my fax service use the FindFax method to check the status, I am getting an empty value returned. Meaning the FaxID couldn't be found? It will find the Fax while it's in the Pending log. The problem becomes when one fax fails/completes.

Code:
fax_item = FaxMan1.FindFax(fax_id)
If IsNothing(fax_item) Then
myLog.WriteEntry("fax_item is empty for fax_id" & fax_id.ToString)
End If

My log is showing:
fax_item is empty for fax_id311

My problem then becomes that the code is inside a larger for loop. So the FindFax code ends up executing over and over again since conditions are not being met to exit. But the weird part is it never finds the fax. It keeps returning an empty value. But I know the fax exists and has completed or failed by looking at the data in the VbNetSample.exe.

Why does FindFax return nothing? And if it can't find a fax once, why can't it find it again later?

I attempted to use QueryLog when FindFax failed to work. And it returned nothing as well. Even though I can clearly see the fax in the FailedLog using VbNetSample.exe...

fax_item = New DataTech.FaxManNet.Fax
Try
fax_item = FaxMan1.FindFax(fax_id)
If IsNothing(fax_item) Then
myLog.WriteEntry("fax_item is empty for fax_id" & fax_id.ToString)
Try
Dim query As String = "FaxID = " & fax_id.ToString & "')"
Dim results As DataTech.FaxManNet.Log = FaxMan1.QueryLog(query)
Dim log_entries As Short = results.Count
If log_entries > 0 Then
myLog.WriteEntry("Found " & log_entries.ToString & " fax entries")
Try
fax_item = results.Item(0)
Catch ex As Exception
myLog.WriteEntry("Error setting fax_item from query: " & ex.ToString, EventLogEntryType.Error)
End Try
End If
Catch ex As Exception
myLog.WriteEntry("Error querying fax logs " & ex.ToString, EventLogEntryType.Error)
End Try
End If
Catch ex As Exception
myLog.WriteEntry("Error Finding Fax: " & ex.ToString, EventLogEntryType.Error)
End Try

Hi Nicole,

Could you email us the database (faxman4.db) file you are using so we can check this out ? Send it to support@data-tech.com and pls reference this thread.

I just found this issue on a server that only had 8 faxes queued.

Send Time         Sent Time        FaxID         Status
9:59                   9:59               1110           Complete
9:59                  10:01              1112           Complete
9:59                  10:03              1113           Complete
9:59                  10:06              1117           Complete
10:07                                      1114           LineBusy
10:12                                      1111           NoConnect   <--- This is when the empty value was returned
10:13                                      1115           NoConnect
10:14                                      1116           NoConnect

 In my testing, I was only seeing the empty value returned when I was getting different failure statuses. At one point I ended up with all the same errors (Timeout) and did not get the error. Again, it doesn't happen all the time so I'm not really sure where the issue is.

I realized my query string was wrong (it had a parenthesis at the end...)

I get this error:

I found a Microsoft kb that I think is related to this issue...
http://support.microsoft.com/kb/923028
I'm trying to see if I can get a hold of the hotfix to test it.

Does Faxman 4.4.4.0 use the .NET Framework 2.0?

I installed the .NET Framework 2.0 SP1 (which includes the hotfix from the kb article) and I'm still getting the error.

Have you had any luck reproducing the issue on your end?

Hi Nicole,

Can you pls email us the exact query and faxman4.db file you are using so we can try to reproduce this ?

Any updates on this issue? I have sent 2 emails previously requesting an update and have not received a response.
