Service Bus associates a message lock with the AMQP link from which the message was received. For the SDK, this means that you must settle the message with the same ServiceBusReceiver instance that you used to receive it.

In your code, you're creating a new receiver for ReceiveMessage call - so when you attempt to complete or abandon the message, you're using a link for which the message is not valid if any other call to ReceiveMessage has taken place.

Generally, you want to avoid the pattern of creating short-lived Service Bus client objects. They're intended to be long-lived and reused over the lifetime of the application. In your code, you're also implicitly abandoning the senders/receivers without closing them. This is going to orphan the AMQP link until the service force-closes it for being idle after 20 minutes.

I'd recommend pooling your senders/receivers and keeping each as a singleton for the associated queue. Each call to SendMessage or ReceiveMessage should for a given queue should use the same sender/receiver instance.

When your application closes, be sure to close or dispose the ServiceBusClient, which will ensure that all of its child senders/receivers are also cleaned up appropriately.

I'd also very strongly recommend refactoring your class to be async. The sync-over-async pattern that you're using is going to put additional pressure on the thread pool and is likely to result in thread starvation and/or deadlocks under load.

UPDATE

To add some additional context, I'd advise not wrapping Service Bus operations but, instead, have a factory that focuses on managing clients and letting callers interact directly with them.

This ensures that clients are pooled and their lifetimes are managed correctly, while also giving flexibility to callers to hold onto the sender/receiver reference and use for multiple operations rather than paying the cost to retrieve it.

As an example, the following is a simple factory class that you'd create and manage as a singleton in your application. Callers are able to request a sender/receiver for a specific queue/topic/subscription and they'll be created as needed and then pooled for reuse.

I would try to select the button by xpath. I think its way more accurate. If your on chrome or fire fox

right click on the an element on the browser

right click and copy and copy by full xpath

To access the field within the iframe so you have to:

• Induce WebDriverWait for the desired frame to be available and switch to it.

• Induce WebDriverWait for the desired element to be clickable.

• You can use either of the following Locator Strategies:

  • Using CSS_SELECTOR:

Okay so, by convention, if you dont already have a Schema file declared create one,something like,

The issue is in these 3 lines.

rename works for me, perhaps you have a function conflict with another package. Try using dplyr::rename.

To change the columns based on range of values you may use case_when or cut.

Private inheritance means that both public and protected symbols from the base class become private symbols of the derived class. private symbols of the base class are inaccessible to the derived class. With exception of private virtual methods which can still be overridden.

this pointers, or in general Class* ptr used inside the class, can access private fields of the class.

Since the symbol Shape::say is public in Shape, it becomes private in Squire(BTW Did you mean Square?). This prevents its usage by public but not by this. Due to rules of virtuals, this "privatizes" the whole chain of overridden methods.

You could do:

Note: Actually your data has 6 columns.
