Delphi: how to call ActiveX Functions that return an OleVariant containing a Byte Array

Delphi ActiveX Event Handling
ActiveX event callbacks can be used to get progress information for lengthy operations, especially for API calls involving communications with servers, such as FTP, SFTP (SSH), IMAP, POP3, SMTP, HTTP, etc. To use an ActiveX in Delphi, the component must be “imported”. This generates wrapper files (TLB.pas) in the “imports” directory, and may also install […]
