Question: I have a need to unzip files from zip files created with Chilkat library, but I would like the library to allow me to specify the ‘SaveAs’ name of the file being unzipped. I have not seen how to do this in the examples or the API documentation. Could you provide any insight into this for me? I saw that I […]
The major new features/fixes for the 8-February-2009 release are: SOCKS4, SOCKS5 Proxy Support for POP3, SMTP, IMAP, FTP, MHT, HTTP, and Socket. The following properties have been added to each component for SOCKS4/SOCKS5 support: SocksHostname, SocksPort, SocksUsername, SocksPassword, and SocksVersion (4 or 5). Setting these properties to non-empty values is all that is required to use SOCKS4 or SOCKS5 proxies. […]
Any date/time property in Chilkat’s Perl implementation is returned as a SYSTEMTIME object. Here is sample code that demonstrates getting the ValidTo and ValidFrom property from a digital certificate: $sysTime0 = new chilkat::SYSTEMTIME(); $cert->get_ValidFrom($sysTime0); $sysTime1 = new chilkat::SYSTEMTIME(); $cert->get_ValidTo($sysTime1); print “Valid from ” . $sysTime0->{wMonth} . “/” . $sysTime0->{wDay} . “/” . $sysTime0->{wYear} . ” to ” . $sysTime1->{wMonth} .

This blog post is an attempt to explain the concepts of asynchronous socket programming using the Chilkat Socket class/component. There are five types of socket operations that may occur asynchronously: Socket read. Socket write. Connect to remote hostname:port Accept connection from client DNS lookup A synchronous socket operation is easy to understand. If you call ReceiveBytes, the method returns only […]
Question: Why is it the return is blank when encrypting chinese characters? Here’s a snippet of my code: crypt.KeyLength := 256; crypt.SecretKey := Password; crypt.CryptAlgorithm := ‘aes’; crypt.EncodingMode := ‘base64’; OutPutStr := crypt.EncryptStringENC(StringToEncrypt); Answer: Strings in some programming languages such as Visual Basic, C#, VB.NET, Delphi, Foxpro, etc. should be thought of as objects. The object contains a string (i.e. […]

ActiveX components and controls are used in many programming languages, each of which has it’s own way of handling event callbacks. This blog post provides helpful hints about how to receive event callbacks from an ActiveX component. To receive the event, you must bind the ActiveX (also referred to as the COM server) event to the implemented interface methods on […]
The first step in debugging a Chilkat method that returns a failed status is to examine the contents of the LastErrorText property. The LastErrorText property will contain information about the last method call on the object. For example: success = mailman.SendEmail(email); textBox1.Text = mailman.LastErrorText; The LastErrorText property is standard on all Chilkat classes/objects. The error information may also be accessed […]
