More on my last post. I’m trying to increase the 1 minute sending timeout because I have service requests that last well over 1 minute. Some maybe even > 1 hour.

I’ve found al ink that explains what can go after the “service:” suffix.

http://msdn.microsoft.com/en-us/library/ms729739.aspx

I’ve tried adding a ‘bindingConfiguration’ and ‘mexBindingConfiguration’ parameters, but I always get a syntax error when instantiating the service via GetObject. I’ve tried several combinations of all the those parameters, but no joy.

Any ideas?

Great article, thanks Damian.

Any idea how can I set the timeout in Excel?

It keeps timing out after 1 minutes and don’t know how to change it. The fact that there’s no XML client .config doesn’t allow me to do it the regular way.

Also, it’d be good to know where can I find the sintax of what (and how) can go after “service:” in the configuration string (addr) you used to call GetObject.

Ignore my last post…just needed to reference my workstation via the IP address, or likely fully-qualified.name.

I was able to get the service working as specified for myself in debug, but other users can not connect (actually send) to the service.

Anything obvious that I need to do?

Hi Damian, thank you for this tutorial (really useful), it works perfectly. Nevertheless I’m still have a limit with this solution, the netTcpBinding offer only 1minute of connection and unfortunately sometimes my Host program needs lot of more… Do you know how I can increase the binding TimeOut in vba ? I’m looking for a solution but I’m empty-handed.
