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.  […]

C++ CkHttp AbortCheck Callback

April 6, 2023 in Callbacks

Chilkat classes that involve network communications can use callbacks. This blog post describes the CkHttp AbortCheck callback. An application can request periodic AbortCheck callbacks according to the HeartbeatMs property setting. (If HeartbeatMs = 0, then no AbortCheck callbacks will occur.) For example:

C Language Callbacks

May 21, 2016 in Uncategorized

This example demonstrates the general pattern for implementing some standard event callbacks functions for the Chilkat “C” API.  All Chilkat “classes” what have events will use the standard Chilkat events shown in the example below (AbortCheck, PercentDone, and ProgressInfo). This example demonstrates callbacks for an SFTP download, but the same technique applies to any other […]

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 […]

HTTP Progress Monitoring in C++

September 14, 2009 in Uncategorized

This blog post shows how to monitor the progress of HTTP uploads and downloads in C++.  The first step is to create a C++ callback class that derives from the CkHttpProgress base class.  You’ll be overriding one or more of the callback methods.  For example: class MyHttpProgress : public CkHttpProgress { public: MyHttpProgress(void) { } […]
