A DIF_NEWDEVICEWIZARD_POSTANALYZE request allows an installer to supply wizard pages that Windows displays to the user after the device node (devnode) is registered but before Windows installs the drivers for the device. This request is only used during manual installation of non-PnP devices.

When Sent

A class installer returns NO_ERROR if it successfully supplies page(s). Otherwise, a class installer returns ERROR_DI_DO_DEFAULT or a Win32 error code.

Default DIF Code Handler

Installer Operation

A DIF_NEWDEVICEWIZARD_POSTANALYZE request allows an installer to supply wizard pages that Windows displays to the user after the devnode is registered but before Windows installs the drivers for the device. This request is only used during manual installation of non-PnP devices.

If an installer adds custom postanalyze page(s), the installer should first check whether NumDynamicPages in the class install parameters has reached MAX_INSTALLWIZARD_DYNAPAGES.

After the user clicks Next on a custom page, Windows installs the drivers for the device and the PnP manager starts the device. A postanalyze wizard page is the last opportunity for an installer to do work before the drivers are loaded and the device is started.

An installer should supply a Wizard 97 header title and a header subtitle in the PROPSHEETPAGE structure for a custom wizard page. An installer should not replace the system-supplied wizard title. See the Microsoft Windows SDK for documentation of the PROPSHEETPAGE structure and for more information about property pages.
