CPropertyPage::OnWizardFinish
当用户单击向导时,完成按钮此成员函数由框架调用。
virtual BOOL OnWizardFinish( );
返回值
非零,则销毁属性表,在完成向导后;否则零。
备注
当用户单击向导中的 Finish 按钮,框架调用此功能;当 OnWizardFinish 返回 TRUE (非零值),属性表可以销毁(不过,实际销毁)。 调用 DestroyWindow 销毁属性表。 不要调用从 OnWizardFinish的 DestroyWindow ;这样做将导致堆损坏或其他错误。
您可以重写该成员函数指定用户必须执行的某些操作,在完成按钮时。 当重写此功能时,返回 FALSE 防止属性表销毁。
有关通知信息的更多信息传播,当用户在某个向导属性表中的"完成"按钮,请参见。Windows SDK的 PSN_WIZFINISH。

示例
// Inform users regarding the selections they have made by
// navigating the pages in propertysheet.
BOOL CShapePage::OnWizardFinish()
{

// Get the number of property pages from CPropertySheet.

int count = sheet->GetPageCount();
// Get the formatted string from each page. This formatted string
// will be shown in a message box. Each page knows about the
// string to be displayed. For simplicity, we derive a class
// from CPropertyPage called CMyPropertyPage. CMyPropertyPage
// has a pure virtual member function called GetPageSelections().
// All pages in the property sheet must be derived from
// CMyPropertyPage so we loop through each page to get the
// formatted string by calling the GetPageSelections() function.
for (int i = 0; i < count; i++)
