Hi All

I would like to ask a question that somewhat relates to this one -> https://bit.ly/3j3rrFT

When I issue the command ConnectToNewObject('Outlook.Application'), Powerbuilder returns -3 => Object could not be created.

Later I found out that when I have an instance of Outlook running on my desktop, where the PB app also runs, the call returns the error code.

However, when there is no Outlook instance running, the app goes pass the call. Then, a process of setting up a new Outlook account commences as though it's a new computer.

 

What should I do to get around it?

Thanks

CJ

Try and see if the same thing happens when you make an executable and run it.

In the past I've seen this behaviour come and go. My guess is that MS is doing updates which fix/break it.

Lately it works for me for both running from the IDE and from executable, but there's been a long time it only worked correctly from the EXE. All of this without doing any code changes.

Also, make sure your anti virus is up to date with it's definitions. Outlook does some kind of checks on that.

One of the things you will experience is the annoying dialog popping up saying " a program is trying to send email ... allow for 10 minutes " or something like that.

One last thing: make sure the user has assigned a "Default Profile" in outlook (there must be a checkbox somewhere to make the choice the default, when you select a profile when using Outlook for the first time).

try connecttoobject, then newobject:

 

iole_outlook = create OLEObject
li_session = iole_outlook.ConnectToObject("","outlook.application")
IF li_session <> 0 THEN
    li_session = iole_outlook.ConnectToNewObject("outlook.application")
    If li_session <> 0 Then
        //"Error: Creating new Outlook session "
         destroy iole_outlook
         return -1
     end if
END IF

...

When there isn't an Outlook instance running already, my app failed at ConnectToObject (returns -5) and Then passed ConnectToNewObject (returns 0) and it goes on the setup process.

Per Miguel's suggestion, your example code works in EXE although it doesn't in IDE.

Thank you, mike S, for your help.
