16 | /* OK, here's how this works. Each of the steps needed for install - | |
17 | dialogs, downloads, installs - are in their own files and have some | |
18 | "do_*" function (prototype in dialog.h) and a resource id (IDD_* or | |
19 | IDD_S_* in resource.h) for that step. Each step is responsible for | |
20 | selecting the next step! See the NEXT macro in dialog.h. Note | |
21 | that the IDD_S_* ids are fake; those are for steps that don't | |
22 | really have a controlling dialog (some have progress dialogs, but | |
23 | those don't count, although they could). Replace the IDD_S_* with | |
24 | IDD_* if you create a real dialog for those steps. */ | |
