how to integerate all steps of the installation in one custom page

[jieyar]

I want to process the installation in one custom page using nsDialogs. Now i can add a custom page and hide the default buttons (cancel, next). In the OnClick function of a custom button with the text "Install", I send BM_CLICK to the hided next button to turn to the instfiles page. But how to integrate and customize the instfiles page in my own page with a custom progress?

Thanks in advance!
