PSM_REMOVEPAGE message

Removes a page from a property sheet. You can send this message explicitly or by using the PropSheet_RemovePage macro.

Parameters

wParam

Zero-based index of the page to be removed.

lParam

The HPROPSHEETPAGE handle of the page to be removed.

Return value

No return value.

Remarks

An application can specify the index or the handle, or both. If both are specified, lParam takes precedence.

Sending PSM_REMOVEPAGE destroys the property sheet page that is being removed.

A number of messages and one function call occur while the property sheet is manipulating the list of pages. While this action is taking place, attempting to modify the list of pages will have unpredictable results. Accordingly, you should not use the PSM_REMOVEPAGE message in your implementation of PropSheetPageProc or while handling the following notifications and Windows messages.

• PSN_APPLY
• PSN_KILLACTIVE
• PSN_RESET
• PSN_SETACTIVE
• WM_DESTROY
• WM_INITDIALOG

If you need to modify a property sheet page while you are handling one of these messages or while PropSheetPageProc is in operation, post yourself a private Windows message. Your application will not receive that message until after the property sheet manager has finished its tasks. Then you can modify the list of pages.

The following notifications are also affected by property sheet modification.

• PSN_WIZBACK
• PSN_WIZNEXT

You can add or remove pages in response to these notifications, provided that you return (via DWL_MSGRESULT) a nonzero value to specify the desired new page. Note, however, that if you remove a page that is located before the current page (that has a smaller index than the current page), PSN_KILLACTIVE might be sent to the wrong page.
