Operation failed

[Guest]

I have written a dll in vb.net to send faxes using the FAXCOMEXLib. The dll
works fine when embedded in a windows application but if i try and embed the
dll in a windows service, when the dll calls the iFaxDocument.ConnectedSubmit
command i receive an operation failed 0x80004005 error. The only explanation
i can come up with is that the FAXCOMExLib needs to be called from an active
form which it doesnt have when running as a service.
Has anyone else experienced this problem and how can i overcome it ?

Thanks in advance

I now have more information. It would appear that the problem is not simply
down to running as a service.
If i click a button on a form to send a fax then everything works fine. If
however the same code gets called from an event (a timer elapsed event) then
the code fails

I now have some more information. It looks like it has nothing to do with the
service.

works fine. However if the code is called from an event e.g. (a timer elapsed
event) then an error occurs
