Retrieve dialog structure from its ID?

[alb_f]

In my code I need to obtain the DIALOG structure from its ID. I can find how to obtain the ID of a dialog but not how to do this opposite. Is there a way to do this?

The code intercepts a key press (PgUp/PgDn) and then determines from the current active dialog ID which follow-up dialog should be started. To start the next dialog I need the full dialog structure since it is passed as a parameter to the routine.

The question lacks quite a few details, is this a quickwin dialog using module iflogm? or is it an sdk dialog? in either case the callback parameters have all the data that is needed to process the callback.

I assume that @alb_f is referring to the DFLOGM DIALOG structure, which can be used in any project type. I admit to being confused by the request, since as @andrew_4619 says, the DIALOG structure is passed to the callback routine. Perhaps more detail would help.
