SLACK CLIENT WINDOW FROZEN WINDOWS
Here is the catch: the problem with having a Microsoft Windows Forms client call these APIs is that they will freeze the UI for significant periods of time. Public Customer GetNextChunk( int chunksize )Ĭustomer cus = new Customer Ĭus.FirstName = r.Next( 3000).ToString () GetNextChunk simulates getting data from a query in pieces, and also has a built-in delay. Method takes a string and returns a string, and includes a 4-second call to sleep to simulate a long call. Our business object has two methods: Method and GetNextChunk. If, in my limited knowledge, I can gain a grasp on them, then they are not too complex for the normal developer. Try to keep an open mind as we analyze these issues they will appear complex at first, but are actually simple.

These helper classes are included in the sample code they should be helpful in writing your own asynchronous APIs. We will also walk through the use and implementation of helper classes which simplify the task of implementing an asynchronous API. This article will focus on these issues by walking through building an asynchronous API for a simple business object. That said, several issues need to be made viable if you want to call objects asynchronously and build asynchronous APIs for your own business objects. Few situations are as frustrating as a frozen UI that can only be cancelled by resorting to Task Manager to kill the process. You could even construct the asynchronous API in such as way as to give progress updates to the caller, and give the client the opportunity to cancel the call. With an asynchronous UI, the client's UI would not freeze. Without an asynchronous API, a client's UI would freeze for the duration of the call. Say, for instance, you have an object that downloads large files from a remote location. If you are creating a Microsoft Windows Forms application, and have an object with methods that may take some time to execute, you may want to consider writing an asynchronous API. If this article appears too referenced without original content, then please let me know what constructive advice I should take. NET developers insist that the future of multithreading involves dividing your application into callback sections. MSDN, amongst others, insist that the future of application programming involves dividing your application into multithreaded parts, because of the growth of the microprocessor industry. This article is largely referenced from the Microsoft MSDN library and assumes a working knowledge of the Microsoft. Simplifying the Use of the APM in Windows Forms
