>I noticed e.g. the helpID = 1231681 will popup the subject "Create an Irregularly Shaped Window Sample" as shown in the solution.vcx, this made me think to make use of this functionality, however I would need to know where to find the individual ID's. Anybody who could shed a light over this?

You can view source in the help (rightclick... and you get some fairly decent html), but as it goes with Microsoft, nothing is easy. There are links to other texts, but they all have a form of a [hex GUID].html, IOW as easy to read as Greek combined with Chinese. I tried

HELP ID 0xd0417150
HELP ID 0x09bb
HELP ID 0x4617
HELP ID 0xa20c
HELP ID 0xe6e4e1e39393

where each hex number is a part of one of these links, and I got exactly nothing.

It's easy to know these IDs when you're writing help as you go, using some software (which you wrote for yourself) which would link your help IDs (.WhatsThisHelpID) to the help IDs in your help files.

To know these IDs retroactively would require some serious reverse engineering and, possibly, lawyers (this is M$, remember).
