There are two possible ways to create an ActiveX within HTML. The first is via an Object HTML tag: <object name=”crypt2″ width=0 height=0 classid=”clsid:3352B5B9-82E8-4FFD-9EB1-1A3E60056904″ standby=”Loading Chilkat Crypt2…” type=”application/x-oleobject” codebase=”http://www.chilkatsoft.com/download/ChilkatCrypt2.cab”> </object> The 2nd way is to dynamically instantiate it within Javascript: var crypt; crypt = new ActiveXObject(“Chilkat.Crypt2”); If the object is created from within Javascript (via CreateObject), then the ActiveX has […]

The Chilkat XML component library (for C#, VB.NET, ASP.NET, ASP, VB6, FoxPro, Delphi, C++, C, Perl, Ruby, Python, Java, etc.) has a number of Search* methods.

Question: What are the reserved characters we have to be aware of when naming folders? Answer: It depends on the operating system and filesystem-type of the computer.
