Error Message: Controls created on one thread cannot be parented to a control on a different thread.

 

We have 25 act users.  One workstation is having serious Act error messages:  "Controls created on one thread cannot be parented to a control on a different thread."

 

 

More Information below...

 

- Version of Act! you are using:

On Windows 10 workstations:  Act Premium 21.1.187.0, Update 4

On Windows 2016 Server:  Act Premium Web 21.1.187.0, Update 4

 

- If the issue involves Microsoft Office (Outlook, Word , Excel), state the version of Office you are using

Doesn't involve Office

 

- Is your database on your local machine (private database) or is it being shared from a server (shared database)?

Shared from a server.

 

- Operating system you have Act! installed on (i.e., Windows 7, Windows 8)

Windows 10 on the workstations.  Windows Server 2016 on the Act server.

 

- As much detail regarding the question or issue as you can provide:

 

This is the only client workstation experiencing this.  Other workstations seem to be fine.  I checked for the following services on the Act Server and they are all running:  SQL Server (Act7), SQL Server Browser, SQL Server VSS Writer.  I tried restarting restarting Act and then restarted the workstation but after reboot the error message comes back.

 

Thanks for your help.

There is a "full hit" in the ACT! knowledge base here:

Thanks, I will try that.  That makes sense if it was a local database on one local machine, but we have the database on a server, and only one user of the shared database is having the issue.

Re: Error Message: Controls created on one thread cannot be parented to a control on a different thread.

This maybe caused by some corruption in the activity area of the database for this user.

 

Here is a link to an article that maybe of help. Clearing up any old activity for the user is also recommended.

I ran database maintenance and so far the "controls created" error message hasn't shown up again, so fingers crossed.  Thanks.
