deactivate speech recognition for ervery command except for activate speech recognition

so I have a lot of commands for my voice assistant that I programmed with visual studio (2019) c# System.Speech and now I want to add a command that deactivates the speech recognition until I say activate speech recognition.
I tried looking through the internet but I haven't found anything yet and I don't know a method myself that would be worth trying. Just deactivating every other command seperatly would be way to much effort.
Does anyone know how to do this or has an idea?
Thx for helping, phantomica

According to your description,when the shutdown command appears, you want to deactivate
speech recognition for every command except for activate speech recognition.
You can follow the steps below to achieve your requirements:
Set a global static variable speechOn, the default value is true.
Try to convert each recognized speech into text and store it in a variable. Then use this variable to compare with "speech on" and "speech off".
Determine the Boolean value of speechOn through the second step. If false, use return; to end the recognition method. If true, continue the recognition method.
My test code is as follows, it was successfully tested.

Multi Client TCP Server not acceping some clients c#

I am trying to make a server that will accept clients, and will communicate with them until they say "exit".
the problem is, after 5-8 clients, the server decides that he don't want to accept any more clients, and when a client is connected.. I simply don't see a "client connected : 123.242.123.13:92313" in the console.
anyone knows the problem?

Basically, what I want to do is to give each client a thread of its own. but after 5-8 connections, the server Socket socketForClient = myList.AcceptSocket(); not working, I think its because I am running out of threads.. but I have no clue why, there should be 1000 threads open when only 5 to 8 connections are made.
please help!

Found out what was the problem, I was highlighting some stuff in the server console, which caused the server to pause.

C# console application stops after nearly 8 minutes

I have a C# console application which reads a folder for every 15 seconds using timer. It works fine,but it pauses after nearly 8 minutes and stops reading folder. Is there any reason for that?

Can anyone guess the issue?

Seems timers are collected by GC. Try to declare timers in outer scope.

private static Timer t2;
...and so on.

MSMQ System.Messaging high resource usage

I have make C# console application which uses timer which connects to MSMQ every 10 seconds get data insert into Oracle database. But the issue is that it log in and log off to domain and create high CPU also create security audit log very much which waste my resources.

How can i solve above issue

Why not host your queue reader process in a windows service. This will continually poll the queue each 10 seconds.
Then use the windows scheduler to start/stop the service at relevant times to create your service window.
This means you won't need to do anything complicated in your scheduled task, and you won't be loading and unloading all the time.

Well from logic you are very correct that I should make windows service not timer service and Task schedule.
But my question was why It is login / log out frequently, which waste the resource of my Domain server. After intense investigation, I found that calling QueueExits is resource critical. Another thing what I found is that when you connect MSMQ queue you are login to share resource, which will login to Domain. As my code was running every 10-20 seconds it was wasting my Domain server resources.
For resolution, I make my MessageQueue object globally in following way
private static MessageQueue mqNewsHeader = new MessageQueue(#".\q_ws_ampnewsheaderrep");
private static MessageQueue mqNewsDetails = new MessageQueue(#".\q_ws_ampnewsrep");
So it will create Once in the life of the Application and we will log in and log out only once. Then I will pass this object to the function as parameter. I see also that my MessageQueue count function was also resource critical, So I change it to following
protected static int GetMessageCount(MessageQueue q)
{
//var _messageQueue = new MessageQueue(queueName, QueueAccessMode.Peek);
//_messageQueue.Refresh(); //done to get the correct count as sometimes it sends 0
// var x = _messageQueue.GetMessageEnumerator2();
int iCount = q.GetAllMessages().Count();
// while (x.MoveNext())
// {
// iCount++;
// }
return iCount;
}
Hope this clear my answer and will help others also.
