All,Jeff Glatt has just updated his article "Embed an HTML control in your own window using plain C"
http://www.codeproject.com/com/cwebpage.asp He has also released "COM in plain C, Part 7" http://www.codeproject.com/useritems/com_in_c7.aspBoth links are excellent sources of "how to" information when dealing with COM/C and the understanding of whole windows API event handling.
Cheers, jez.
