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, Perl, Python, VB6, VBScript, DataFlex, […]
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:
Here’s a C# class for persisting a TreeView to JSON, and for restoring a TreeView from JSON.
Here are a few snippets of code I needed for internal tools… TreeView –> JSON JSON –> TreeView
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 Chilkat “class”, such as HTTP, […]
This example demonstrates how to open a remote file on an SSH/SFTP server, write to the file, and then close it. This is analogous to opening a local file, writing to it, and closing it. The SFTP protocol (i.e. Secure File Transfer over SSH), follows the same concepts as typical file I/O programming — i.e. open a file, read, write, […]
This sample C# snippet demonstrates how to use the TaskCompleted event to be notified when an asynchronous method completes. Given that the event callback is in the background thread, any UI updates must occur on the main thread. This example demonstrates how to do it:
