显示模态子对话框时出现问题

问题描述

我的项目是基于对话框的MFC项目.我的父对话框的类名是CdialogchangDlg，我的子对话框的类名是CPicture2和CPicture3.我可以访问我的子对话框.现在，我想从一个子对话框转到另一个子对话框，我使用按钮来执行此操作.

代码是:

My project is a MFC project based on dialogs. The class name of my parent dialog is CdialogchangDlg and my child dialogs are CPicture2 and CPicture3. I can access my child dialogs. Now I want to go to another child dialog from one child dialog, I use buttons to do this.

The code is:

void CPicture2::OnBnClickedButton1()
{
	CPicture3 pic3;
	OnOK();
	pic3.DoModal();
}

和

and

void CPicture3::OnBnClickedButton1()
{
	CPicture2 pic2;
	OnOK();
	pic2.DoModal();
}

该程序运行没有问题.但是，当我单击按钮约300次以在两个子对话框之间切换对话框时，该程序已死.当我单击按钮时，我发现分配给程序的内部存储器会无休止地增加，直到程序死了.有人说，当我使用DoModal()时，当前对话框并没有真正被销毁.真的吗?我该如何解决这个问题?
我是新生，谢谢.

The program runs without problems. But when I click the button about 300 times to change dialog box between the two child dialogs the program is dead. When I click the button, I find the internal memory gave to the program go up with no stop until the program is dead. Some people said when I use DoModal() the current dialog is not really destroyed. Is that true? And how could I resolve this problem?
I am a freshman, thank you.
