Calling main thread from a worker thread

Hi folks, I originally posted this on microsoft.public.dotnet.framework.interop. Reposting to broaden the audience. I'm having an interop problem where my managed component is reentered from COM on the wrong thread, at which point things seem to go downhill very rapidly. I'm successfully making very heavy use of COM interop elsewhere in my C# code, but I'm having trouble finding a way around this particular problem. This is VS .Net 2003.

I have a multi-threaded C# console application that uses WMI (System.Management namespace) to make RPC calls to several servers (600+ ) and returns ScheduledJobs. The section of my code that performs the query is contained in a delegate function that I execute via a second thread. On 1 or 2 of the 600+ servers the query hangs. I've tried to use Thread.Join() coupled with a Thread.Abort() but this does not kill the thread. Based on...

For example, void WorkerMethod() { ... UnregisterAllHotkeys();} void UnregisterAllHotKeys { for(...) {UnregisterHotKey(...);}} UnregisterHotKey is an API function that must be on the thread that RegisterHotKey was called in order to unregister any of the hot keys RegisterHotkey registered. ("The UnregisterHotKey function frees a hot key previously registered by the calling thread.") Is there any way to call UnregisterAllHotkeys, a...

I found this awesome example of calling a Main Thread from a worker thread on abstractvb.com but I read through the example and would like to see if anyone can clarify some of this code below: Questions: 1. The Public Sub New proceedure. Is that just a proceedure named new or is there more to this? I went through the code and I do not see any refrences to 'New'

I know how to call a the main thread from a worker thread in a windows form class, but how does a worker thread call its main thread from a none windows form class? Thank You.

The are 2 threads - main thread and worker thread. The main thread creates the worker thread and then the worker thread runs in an infinite while loop till it is asked to exit by setting an event. The worker thread instantiates an object and calls methods of that object. If some method call fails, the main thread needs to be notified about the failure. What mechanisms exist for notifying the main thread about the worker thread's status -...

I have an object that spawns a worker thread to process one of its methods. That method processes methods on a collection of other objects. During this processing, a user may request to cancel the entire operation. I could request abort on the worker thread, but that is a) potentially messy, and b) not guaranteed to take immediate effect anyway. I would rather have some way of allowing the main thread to tell the worker thread that it...

Hi, As a matter of principle I have refranied from creating an instance of Form or UserControl from within a class that does not inherit from System.Windows.Form. I am looking for comments on Pros and Cons of the approach. My logic has been that UI is always executed on the main application thread. I use Control.InvokeRequired or delegates to ensure that I am

Hi, I have an existing VC 6 MFC application which communicates asynchronly with a VC 2005 managed code dll. I use an unmanaged base class with virtual functions to access methods in the MFC application. Furthermore, I use a pointer to an unmanaged function to jump back into the managed dll. The managed part is basically a remoting enhancement which asynchronly

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. 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,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own.... Now, this would greatly impact the work of software developers. The idea...

Hello I'm a network technician in training and I need your help. I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs. The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols. I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
