(C++) Return Email Headers as iso-8859-15? (or any other charset)
Question: In C++, is it somehow possible to specify a desired charset (like ISO-8859-15) when getting mail headers with POP3? Answer: Instead of calling the method that returns a “const char *” — which can return either utf-8 or ANSI (see this Chilkat blog post about the Utf8 property common to all Chilkat C++ classes), […]

Very simple C# SSH Shell Console Terminal
Here’s an example that demonstrates a rough start to creating a C# console SSH shell terminal (where the user can type commands and output from the remote command echos to the console: using System; using System.Collections.Generic; using System.Text; using System.IO; namespace SshTerminalConsole { class Program { static void Main(string[] args) { Chilkat.Ssh ssh = new […]
Aborting in C++
The technique for aborting any time-consuming Chilkat C++ method call follows this recipe: Declare your own class that derives from the appropriate Chilkat progress monitoring class. For CkMailMan it is CkMailManProgress (as shown below). For other Chilkat classes it is CkHttpProgress, CkFtpProgress, CkImapProgress, CkZipProgress, etc. Create an implementation for the AbortCheck method. This will override […]
Socket SendString (C++) w/ TCHAR
Question: I need to send a unicode string (e.g TCHAR *ptr) but the API only allows to send char. Answer: /* The _TCHAR data type is defined conditionally in Tchar.h. If the symbol _UNICODE is defined for your build, _TCHAR is defined as wchar_t; otherwise, for single-byte and MBCS builds, it is defined as char. […]
Is Calling .Dispose() Recommended for C# and VB.NET?
Question: In your examples online, we have noticed that .Dispose() is never called after using Chilkat classes (we are writing in C#). Is calling .Dispose() recommended? Does your code not need to destroy any native resources or handles that would normally be cleaned up in the Dispose method (the IDisposeable interface) ? Answer: For objects […]
Chilkat C++ Libs – Link and Maintain Single EXE?
Question: I am developing a single EXE in C++ that doesn’t make use of any external libraries and including MFC. Can I add your zip libaries to my application and still maintain the application as a single EXE? Answer: Yes, the Chilkat C++ libs may be linked directly into your application. This results in a single […]
HTTP Progress Monitoring in C++
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) { } […]
Scan/Replace Text in Email Body in C++
This example may help C++ programmers needing to scan email bodies for strings and automatically replace: void EmailBodyExample(void) { CkEmail email; // Set the plain-text and HTML alternative bodies. // Note: Because we’re using literal strings, the strings passed // to these methods are ANSI strings (i.e. they are 1-byte per char // in this […]
SFTP Progress Monitoring and Abort (C#)
Here is an example for monitoring the progress of an SFTP file transfer: void sftp_OnPercentDone(object sender, Chilkat.PercentDoneEventArgs args) { progressBar1.Value = args.PercentDone; // To abort at any point, you may set args.Abort = true // args.Abort = true; } void sftp_OnAbortCheck(object sender, Chilkat.AbortCheckEventArgs args) { // See https://cknotes.com/?p=149 for more information about // using the […]
