问题描述
亲爱的,
我正在创建一个从CDialog派生的类,假设该类名称为"CBase".
我希望它充当MFC的CDialog,并且从基类派生的任何类都将创建一个对话框.我该怎么办?
我尝试过休假
dear,
I''m creating a class derived from CDialog, suppose that class name it is ''CBase''.
I want it acting as CDialog of MFC and any class derived from base create one dialog box. What can I do for it?
I tried out as fallows
CBase : public Cdialog
{
CBase(CWnd* pParent = NULL); // standard constructor
//{{AFX_DATA(CTestDlgBase)
enum { IDD = _UNKNOWN_RESOURCE_ID_ };
protected:
virtual void DoDataExchange(CDataExchange* pDX); // DDX/DDV protected:
DECLARE_MESSAGE_MAP()
}
Cderive : public CBase
{
Cderive(CWnd* pParent = NULL);
//{{AFX_DATA(CTestDlgBase)
enum { IDD = _UNKNOWN_RESOURCE_ID_ };
protected:
virtual void DoDataExchange(CDataExchange* pDX); // DDX/DDV protected:
DECLARE_MESSAGE_MAP()
}
但由于休假而出现错误
错误C2065:"_ UNKNOWN_RESOURCE_ID_":未声明的标识符
错误C2057:期望的常量表达式
当我创建类CBase&的对象时调用DoModal时,对话框未显示.
我该怎么办?
but I got error as fallows
error C2065: ''_UNKNOWN_RESOURCE_ID_'' : undeclared identifier
error C2057: expected constant expression
also when I create object of class CBase & calling DoModal the dialog isn''t shown.
What can I do for it?
