分享模态对话框选择if(IDCANCEL == dlg.DoModal())后怎么关闭它
我没有写if(IDCANCEL == dlg.DoModal()) 只写了个
if(IDOK == dlg.DoModal())
结果报错了
if(IDOK == dlg.DoModal())
结果报错了

找到了，我擅自释放了一个指针导致的

还是没有贴关键的代码~

内存泄露的地方，你双击一下看看指在哪行代码？

这是对话框的里面，你看看
#include "stdafx.h"
#include "Cpen.h"
#include "mydialog.h"
// Cmydialog 对话框
IMPLEMENT_DYNAMIC(Cmydialog, CDialog)
Cmydialog::Cmydialog(CWnd* pParent /*=NULL*/)
: CDialog(Cmydialog::IDD, pParent)
{
}
Cmydialog::~Cmydialog()
{
}
void Cmydialog::DoDataExchange(CDataExchange* pDX)
{
CDialog::DoDataExchange(pDX);
DDX_Control(pDX,IDC_EDIT1, name);
DDX_Text(pDX, IDC_EDIT2, width);
DDX_Text(pDX, IDC_EDIT3, height);
DDX_Text(pDX, IDC_EDIT4, dext);
DDX_Control(pDX, IDC_COMBO1, box);
}
BEGIN_MESSAGE_MAP(Cmydialog, CDialog)
END_MESSAGE_MAP()
// Cmydialog 消息处理程序

那要看你的Cmydialog 类中写了些什么？是否有设计内存分配的调用？

我不记得我申请了啥内存啊，我只是定义几个控件变量而已。
然后在Cpen的构造函数中初始化
CpenView::CpenView()
{
Cmydialog backnew;
backnew.width=400;
backnew.height=500;
backnew.dext=2;
if(IDOK==backnew.DoModal())
{
m_width=backnew.width;
m_height=backnew.height;
}
}

这个内存泄露跟模态对话框没关系，你在对话框代码中进行了动态内存的申请动作，所以你必须自己释放掉动态申请的内存，才不会报内存泄露的。

囧，那跟DoModal()有什么关系，你要检查一下你分配内存资源的地方啊~

确实关闭了，结果也内存泄漏了

DoModal()以后就会关闭当前模态对话框了
