在代码最低下我加了这段代码，当点击后弹出新的窗口，我现在想弹出后显示hello world新窗口怎么做？ 最好是比原先的窗口小一点，现在弹出的窗口和原先的窗口一样大！不好区分!

void CDialogDlg::OnBnClickedOk()
{
// TODO: Add your control notification handler code here
//OnOK();
CDialogDlg* p = new CDialogDlg();
p->DoModal();
}
很新鲜的代码。你用的相同的对话框资源，自然显示后大小是一致的了。

void CDialogDlg::OnBnClickedOk()
{
// TODO: Add your control notification handler code here
//OnOK();
CDialogDlg* p = new CDialogDlg();
p->DoModal();
delete p;
}

OnInitDialog()中添加如下
{
CDialog::OnInitDialog();
if(CWnd *pWnd=GetOwner())
{
CRect rect;
pWnd->GetWindowRect(rect);
rect.DeflateRect(10,20,30,40);
MoveWindow(rect);
}

[vcmute]

if(CWnd *pWnd=GetParent())也可

横秋不错！

OnInitDialog()中添加如下
{
CDialog::OnInitDialog();
if(CWnd *pWnd=GetOwner()) //GetOwner()如果不为NULL的话，就证明是子窗口。
{
CRect rect;
pWnd->GetWindowRect(rect);
rect.DeflateRect(10,20,30,40); //缩小窗口边框
MoveWindow(rect);
}


这段代码是做什么？ 谁能告诉我谢谢！

MoveWindow(rect);
设置窗口大小和位置

[whitechocolate]

能不能详细的讲讲！谢谢

[whitechocolate]

急啊，谁能帮解决！

[东方匠心]

MoveWindow可以改变窗口的位置和大小
你在窗口初始化的时候调用
你想放到哪　多大你可以自己定义

[AntonlioX]

up

[oyljerry]

在初始化中设置自己需要的大小
