Background Query Completion

I have created a VBA code to import data from CSV convert it into a table and refresh the query that is already setup.

I want the user to be informed when the background query is completed by displaying a VBA msgbox.

How to sync background query completion with VBA msgbox?

Is there anyother way to display background query completion.

      Hi PowerBI_Query,

       

      Well done!

      Sorry, misunderstood the requirements. The code that you've posted is not running queries in the background, therefore the user would not be able to do anything until it is completed. My initial thought was that you want the query to run in the background while the user is working on something else and notify once completed to track their attention.

       

      Cheers,

      John

    I am not aware of this being possible. There is no trigger from Power Query refreshing in the background that the VBA object model can pick up on, but to be 100% sure your best bet is in the VBA forums of the Excel groups. This is a Power BI forum and it doesn't have, nor will ever have, VBA.

    Hi PowerBI_Query,

     

    You need to capture QueryTable_AfterRefresh event in VBA. How to do it is quite separate question. Search on the Internet as non-standard events may at time be quite complicated, it depends on the scenario you would like to implements, etc.

     

    Kind regards,

    John
