CDialog的用法误区

CDialog的用法

//继承CDialog实现一个自己的对话框
class CMyDialog:CDialog
{
public:
    CMyDialog(UINT uIDTemplate = IDD, CWnd* pParent = NULL);
    ~CMyDialog(); 
    {IDD = IDD_MYDIALOG}
    MyCreate();
}

CMyDialog::CMyDialog(UINT uIDTemplate, CWnd* pParent)
:CDialog(uIDTemplate, pParent)
{
  
}

CMyDialog::MyCreate()
{
    Create(IDD, GetParent());
    //注意这里GetParent将返回一个空的句柄,从而导致父窗口是Application的顶级窗口
}

CMyDialog myDlg = new CMyDialog(IDD, pParent);
myDlg->MyCreate();
