Check login of user using the Acrobat library

[Programming-Newbie]

Hello Adobe Support Community,

I'm new to the Acrobat SDK and have only used some of the features. I'm using the Acrobat library through VB.NET right now and I'm trying to check, if an user is actually logged in in Acrobat at the time he's using the program I wrote.

Because I will get an error message everytime if I'm not logged in.

Is there a way through the Acrobat library to check this?

What API does you use?

Hello Bernd!

I don't know if this answers your question but I used this documentation guide for my code:

https://opensource.adobe.com/dc-acrobat-sdk-docs/acrobatsdk/documentation.html

I did import the reference "Adobe Acrobat 10.0 Type Library" to my project and used the following objects to work with:

Acrobat.AcroApp and Acrobat.AcroPDDoc

Thanks!

Oops, wrong link. This is the link I wanted to share:

The IAC API doesn't have a function for this.

Thanks for your answer! Do you have any idea if there is another way to get this working?

What error message do you get, exactly?

I've attached the error message. I found out that I get this error message when I'm not logged in Acrobat.

But I think this error message will not get me anywhere near the answer to my question 😄

Thank you. I wanted to see if this was a message from Acrobat that could be trapped. Adobe give no method or API to look at licensing status, this seems to be a secret. Instead Acrobat is just closed down; it does not set up its COM interfaces.

So, this message needs to be trapped (if it can be) at the level of COM.

Yes I was thinking the same going through this question. Sadly Adobe does not support kind of a feature like that but I can understand it also.
