如何关闭从类到另一个类的无模式窗口 [英] How to close a modeless window from class to another class

问题描述

我通过WM_TIMER函数中的另一个对话框创建了无模式对话框.我的对话框已经完成，我想通过代码自动销毁它，所以我按照以下方式完成了

I have created Modeless dialog through another dialog in the WM_TIMER function.And my work is done with the dialog i want to distroy it automatically through code.So i have done in the following way

OnTimer:
{
 ClsWindow *m_pWindow = new ClsWindow;
if(Aflag == true)

 m_pWindow ->Create(ClsWindow::IDD)
 m_pWindow->ShowWindow(SW_SHOW)
}

else
{

 m_pWindow->DestroyWindow()
}

这里的问题是我能够创建无模式对话框，但我无法破坏窗口.如果我不使用计时器，并且如果在任何按钮单击事件中使用此代码，则此代码有效，它可以正常工作.正在连续运行，无法破坏窗户.请建议我解决此问题.

在此先感谢.

Thanks in Advance.

推荐答案

每次输入OnTimer时，都会创建一个新的ClsWindow，以防万一标志==假的，你摧毁它.离开OnTimer处理程序后，要关闭的窗口的指针在创建后已经丢失.
ClsWindow *m_pWindow的属性需要在类级别定义，并且在进入OnTimer时不仅要覆盖它.

Every time you enter OnTimer you create a new ClsWindow and in case flag == false you destroy it. The pointer to the window you want to close was already lost after creation when leaving the OnTimer handler.
A property for ClsWindow *m_pWindow needs to be defined at class level and don''t just overwrite it when entering the OnTimer.

OnTimer:
{ 
  if(Aflag == true)
  {
    m_pWindow = new ClsWindow;
    m_pWindow ->Create(ClsWindow::IDD)
    m_pWindow->ShowWindow(SW_SHOW)
  } else
  {
    m_pWindow->DestroyWindow()
  }
}

祝你好运！
