Chilkat C++ Libraries safe for multi-threading?
Question: Are the Chilkat C++ libraries safe for multi-threading? Answer: Yes. However, it is best practice that you don’t allow multiple threads to call methods on the same object instance at the same time. Also, objects that communicate via an Internet protocol, such as SMTP, POP3, IMAP, FTP, HTTP, etc. should not be shared between […]
No messages in POP3 mailbox?
Question: I am reading my POP3 mailbox by calling mailman.CopyMail. It returns a bundle object, but the bundle.MessageCount = 0. I know there are emails in the mailbox. What happened?

C# Encrypting/Decrypting with Stream
This C# example demonstrates how to use Chilkat.Crypt2 to encrypt and decrypting using the .NET FileStream class: Chilkat.Crypt2 crypt = new Chilkat.Crypt2(); bool success = crypt.UnlockComponent("Anything for 30-day trial"); if (!success) { MessageBox.Show(crypt.LastErrorText); return; } crypt.CryptAlgorithm = "aes"; crypt.CipherMode = "cbc"; crypt.KeyLength = 128; crypt.SetEncodedIV("0000000000000000", "hex"); crypt.SetEncodedKey("abcdefghijklmnop", "ascii"); // Open input and output files as […]

Bandwidth throttling small amounts of data.
Question: I’m sending ~50kb jpeg files alongside a very bandwidth-intensive application, so I want to make sure that my application doesn’t use more than 10kb/s, so that even those with slow connections will not have this other application impacted by mine. Answer: Concerning bandwidth throttling — it only makes sense with larger amounts of data […]
POP3 Change Password Programmatically?

XML Methods Ending in “2” (GetRoot2, GetChild2, GetParent2, NextSibling2, …)
A Chilkat XML object represents a single node within an XML document. The “root” is the topmost node in the XML document tree. As long as at least a single reference to a node (anywhere in the tree) exists, the entire XML tree remains in memory. Typically, an XML API returns a new node object […]
SMTP Protocol (in a Nutshell)
Question: SendMime requires a from and recipients address string, but the MIME message contains both . The message I receive from the SendMime seems to ignore the addresses in the call and uses the one in the MIME. So why require a from and recipient address? Answer: The SMTP protocol works like this: 1) A […]
