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()
{
   CString report = _T("You have selected the following options:\n");

   // Get the number of property pages from CPropertySheet.
   CPropertySheet* sheet = (CPropertySheet*) GetParent();
   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++)
   {
      CMyPropertyPage* page = (CMyPropertyPage*) sheet->GetPage(i);
