Semantic Versioning Starting with Chilkat 10.0.0

Pinned September 26, 2024

Starting with the v10.0.0 release (end of September 2024), Chilkat moves to standard semantic versioning.   Prior to this release, for various technical reasons, Chilkat was stuck with versions 9.5.0.xx, where only xx changed. For this first leap to semantic versioning, where the major version changes to 10 (from 9), there are no backward incompatible changes.  […]

Wrapping a Chilkat Synchronous Method in C# async/await

October 31, 2024 in Async

Chilkat provides its own Async functions, separate from C#’s async/await. For each synchronous Chilkat function that may take time due to network communication or other factors, an Async version is also available, returning a Chilkat Task object (distinct from C#’s Task object). Chilkat’s Async functionality exists in all of the programming languages: C++, PHP, Ruby, […]

What Replaced Old Chilkat Async Methods?

May 8, 2024 in Async

In the distant past, there were some Chilkat classes that had a few ad-hoc Async methods and properties.  For example, the Ftp2 class contained the methods AsyncPutFileStart, AsyncGetFileStart, AsyncAppendFileStart, and properties such as AsyncFinished, AsyncSuccess, and AsyncLog. A number of years ago, these were replaced with a consistent and standard async model that applies to […]

Q/A 11-Nov-2019 (Thread Safety)

November 11, 2019 in Uncategorized

Question: We have a desktop application(client) that can communicate to many devices(servers) at the same time. A different thread pool is used for each device communication, so they do not block each other or the main thread. Because of the issue earlier, I am using the same http object for all communications. Most of the […]

Visual Foxpro IDE crashes when using asynchronous socket methods

November 23, 2018 in Uncategorized

Question: When using asynchronous socket methods, VFP crashes. Try running the code from the example under VFP https://www.example-code.com/foxpro/socket_async.asp What else do I need to configure? Answer: The older IDE’s such as VB6 and FoxPro don’t take kindly to background threads.  The solution is to clean up the threads at the end of your program by […]

Node.js Asynchronous Methods that Return Objects

October 29, 2018 in Uncategorized

This post shows the general technique to get the object returned by a method when it is called asynchronously.   For example, consider the Mailman.GetUidls() method.  A synchronous call to GetUidls returns a StringArray object, as shown here: However, the async version of the method, GetUidlsAsync, returns a Task object. The TaskCompleted callback is called […]

Asynchronous Chilkat Methods in Node.js

September 25, 2015 in Uncategorized

Chilkat implements a thread pool for asynchronous tasks in all programming languages except for Node.js. For Node.js, Chilkat tasks run directly on Node’s internal thread pool (i.e. the libuv thread pool). The Task.Run() method can have 0 or 1 arguments. If an argument is passed, it is the “task completed” callback that get called when […]

Event Callbacks in Java

August 22, 2015 in Uncategorized

Event callbacks in Java (including Android) are supported starting in v9.5.0.52. To receive event callbacks, first create a Java class derived from one of the Chilkat event callback classes. The event callback classes are: CkBaseProgress, CkHttpProgress, CkZipProgress, CkFtp2Progress, CkMailManProgress, CkTarProgress, and CkSFtpProgress. All future Chilkat classes will only use CkBaseProgress. Theses event callback classes will […]

VB.NET TaskCompleted Event for Asynchronous Method Call

August 21, 2015 in Uncategorized

Demonstrates a TaskCompleted event for an asynchronous Chilkat method call. The event callback occurs in the background thread, and therefore any updates to the UI must happen on the UI thread. For this reason, MethodInvoker is used to make updates to a TextBox..
