MFC_代码使用

流程

Main

//.h
class CTestApp : public CWinApp
{
public:
    CTestApp();   

public:
    virtual BOOL InitInstance();  

    DECLARE_MESSAGE_MAP()
};

// .cpp
BEGIN_MESSAGE_MAP(CTestApp, CWinApp) 	
END_MESSAGE_MAP()

 CTestApp theApp;    
  
 CTestApp::CTestApp()
 {
  
 }
  
 BOOL CTestApp::InitInstance()
 {
   InitCommonControls();
   CWinApp::InitInstance();
  
   CTestDlg dlg;
   m_pMainWnd = &dlg;
   INT_PTR nResponse = dlg.DoModal();

   return FALSE;
 }

DECLARE_MESSAGE_MAP

1. 有了 DECLARE_MESSAGE_MAP
    必有 BEGIN_MESSAGE_MAP(CTestApp, CWinApp)
           END_MESSAGE_MAP()

CDialog + 构造函数

//.h
#include "afxcmn.h"
class CTestDlg : public CDialog
{
public:
    CTestDlg(CWnd* pParent = NULL);

    enum{ IDD = IDD_DIALOG1 };
protected:
//     virtual BOOL OnInitDialog();
};

// .cpp
CTestDlg::CTestDlg(CWnd* pParent /*=NULL*/):CDialog(CTestDlg::IDD, pParent)
{
//     m_hIcon = AfxGetApp()->LoadIcon(IDR_MAINFRAME);
}

列表

mfc头文件列表

“afxcmn.h”       //MFC控件
“afxwin.h”       //MFC windows框架
“afxframe.h”
