Title: ERR option ignored
Post by: Thomas Bock on July 20, 2022, 10:42:32 AM

For a few weeks we encounter a strange error 65 every now and then, when our programs create a COM object.

Code: [Select]

ON_CREATE:
def object outlook, "[LCL]Outlook.Application", err = *next
if not(tcb(2)) then nameSpace = outlook'getNameSpace("MAPI")
returnThis has been a save way ever since. On the WindX side MSG(-1) returns "Exception occured (err/ret=2/0)"
According to Eric we should check for the object reference > 0. But I wonder why the err option is ignored in these cases.

Can you confirm the error is on the DEF OBJECT or the call to getNameSpace?

The error is thrown by the NEW() function. The constructor as already been left, so I cannot check anything inside the object any more.

I am not certain I follow what is happening. 

If you have an error on the DEF OBJECT you probably should force an error exit on the ON_CREATE otherwise your object will be instantiated without a valid Outlook object.

As for why the object creation fails, we have seen instances where Outlook itself is busy doing something (asking a user a question such as "Delete email?". updating mail from host, sending mail, updating calendar, ...) it doesn't accept a new connection.
