Routine Description:

  (B) Offers them an ability to skip joining a domain, and go into

  already has the correct domain name in it.

Arguments:

  hdlg - Handle to the wizard page; its parent is the wizard frame

  uMsg - Message to process

  wParam - Message data

  lParam - Message data

Return Value:

  TRUE if the message was handled, or FALSE if not.

  Exception:

                       page to be skipped; TRUE causes page to be processed.

Routine Description:

  UI_DomainPageProc implements a wizard page that:

  (A) Asks to select find an existing computer account, or to provide
      information to create a computer account.

  (B) Offers them an ability to enter the credentials to create an account,
      or provide the name of a domain that has an account.

  Before showing this page, we verify it is supposed to show up by
  checking several special conditions where the page is not necessary.

Arguments:

  hdlg - Handle to the wizard page; its parent is the wizard frame

  uMsg - Message to process

  wParam - Message data

  lParam - Message data

Return Value:

  TRUE if the message was handled, or FALSE if not.

  Exception:
    WMX_ACTIVATEPAGE - If called for activation, return of FALSE causes the
                       page to be skipped; TRUE causes page to be processed.

                       If called for deactivation, return of FALSE causes the
                       page not to be deactivated; TRUE causes page to be
                       deactivated.

Routine Description:

  NameCollisionPageProc presents a wizard page when one or more incompatible
  names are found on the Win9x machine.  Setup automatically generates
  replacement names, so this page is used to adjust what Setup comes up with.

  If there are no incompatible names found on the Win9x machine, or if
  Setup is in unattended mode, this page is skipped.

  The following names are tested:

    Computer Name - Must be alpha-numeric, or with dash or underscore.
                    Spaces are not permitted.

    Computer Domain - If machine is set to participate in an NT domain, then
                      Setup must guess at what the correct computer domain
                      is, since Win9x does not enforce this name.

    User Names - Setup checks each user name to make sure it is valid.   Most
                 of the problems are conflicts with NT group names, such as
                 Guests.


Arguments:

  hdlg - Handle to the wizard page; its parent is the wizard frame

  uMsg - Message to process

  wParam - Message data

  lParam - Message data

Return Value:

  TRUE if the message was handled, or FALSE if not.

  Exception:
    WMX_ACTIVATEPAGE - If called for activation, return of FALSE causes the
                       page to be skipped; TRUE causes page to be processed.

                       If called for deactivation, return of FALSE causes the
                       page not to be deactivated; TRUE causes page to be
                       deactivated.

Routine Description:

  pDoPostReportProcessing contains all of the code that needs to be run after
  the report has been generated for the user but before continuing on with
  the upgrade. This includes tasks like checking to make sure there is enough
  disk space, that there aren't files installed that we can't continue with,
  that the user actually looked at the report, etc. This code is run in both
  the attended and unattended case. Make sure your additions are properly
  protected by the unattended flag if needed.

Arguments:

  hdlg           - the dialog window.
  UiTextViewCtrl - The window to the report text.
  WarningGiven   - Wether the user has looked at the report or saved it.
  TurnOffUnattend - Wether we should return to attended mode.

Return Value:

  TRUE if it is ok to proceed with the upgrade, FALSE otherwise.

Routine Description:

  UI_BackupYesNoPageProc is the wizard window procedure that is called to
  backup asking page. User can choose to do backup or not. In the unattended
  case, this page will not appear, but we do some validation for the backup
  impossible page.

Arguments:

  hdlg      - Specifies the dialog handle

  uMsg      - Specifies the message to process

  wParam    - Specifies the wParam data associated with the message

  lParam    - Specifies the lParam data associated with the message

Return Value:

  WMX_ACTIVATEPAGE: On activation (wParam is TRUE), returns FALSE if
                    page is to be skipped; returns TRUE if page is
                    to be processed.
