Perl Date/Time Properties
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} . ” […]

ActiveX Events in FoxPro
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 […]
Client-Side SSL/TLS Authentication
This blog post is here to clarify a very common misunderstanding. The various Chilkat components that provide SSL/TLS support also provide an option that allows a client-side digital certificate to be used with the secure connection. A certificate identifies you to the server. In 99% of cases you do not need a client certificate. It […]
