COBRAS Data Viewer error 3709

Answered Question
Apr 8th, 2010

Hey guys --

I am currently getting an error while running COBRAS Data Viewer, as soon as I run the application and select the database that I exported, I get the following error:

(error): 3709 (The connection cannot be used to perform this operation.  It is either closed or invalid in this context.) in procedure listHandlers_Click of From frmMain

I have to click 'OK'  couple times to clear the message.  Then everytime I select a subscriber, the same error appears.

Any thoughts?

hmmm... not sure what's up with that.

Moved it to the primary download site:

build 26 should be out there now.

What version of the data viewer are you using?

What version and product backup are you trying to open?

Lindborg, you are insane. =)

Thanks for the quick reply.  I am running Data Viewer version 1 Build 25.

Trying to open a Unity Connection backup Version 7.1.3.  Oddly enough, when I open the UnityDataDB backup it gives the error; however, when I try to open the UnityMessage backup, it seems to work fine.

Any help is appreciated.

hmmm... I'm running build 25 as well and I just opened several 7.1(3) backups I have - no problems.  Can you select the "Backup Details" option

and post for me the details it kicks out for your backup?  i'm guessing the backup was made with an older version of Export and a column name it's expecting to be there in the backup is not - i'll need to add logic so "if version is less than X" it doesn't attempt to fish that value.

ah... opposite problem - the latest version of export includes additional SMTP data (proxy addresses among other things) - looks like it's trying to fetch that but bungling on me - let me get a fix for it real quick...
