Can BackgroundWorke r be Single Threaded Apartment?

=?Utf-8?B?SGFycnkgS2Vjaw==?=

I have introduced a component to my solution that is throwing an exception
about needing to be run in single threaded apartment mode. This component is
created in an async call by a BackgroundWorke r object, which seems to be on a
MTA thread. Is there a way for me to get the BackgroundWorke r thread to run
in STA mode, or do I have to remove the BackgroundWorke r and hand spin my own
async call?

Which VB (classic or dotNet) are you using?

BackgroundWorke r will typically use the thread pool, and AFAIK those are
always MTA threads. Even if they're not, forcing the current
BackgroundWorke r thread to be STA could cause other things to break,
because the threads are shared.

In other words, I think that not using BackgroundWorke r is the correct
approach. If you have to have an STA thread, you should create your own
thread for the purpose so that you can control its apartment model
explicitly.

Hi. I'm having difficulty calling a 3rd party COM object that must be called in the apartment (single) threaded model. As far as I know, there are 3 ways todo this: 1 - use "aspcompat=true" for aspx pages 2 - use attribute for windows/console applications 3 - use System.Thread.CurrentThread.ApartmentState = ApartmentState.STA

I have an application that creates a pretty intensive TreeView at startup time. I had the program running on a single thread sucessfully, but the startup time was a bit excessive.

I have all the code running on the thread OK, but I cannot figure out how...

I'm using a BackgroundWorker to perform a file download from an ftp site.

This all works great when I'm NOT using Threading (BackgroundWorker), however, as soon as I...

Load secondary form in backgroundworker thread

I'm completely new to using background threading, though I have downloaded and run through several samples and understood how they worked. My question is: I have an app whose primary form will almost always lead to the user opening a certain child window that's fairly resource intensive to load. Is it possible to load this form in a backgroundworker and then use the Show method and hide method as necessary? Anyone know of

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
