3.2 CreatGraphDlg.cpp和CreatGraphDlg.h的实现 // CreatGraphDlg.cpp : implementation file #include \标准AFX头文件 #include \#include \#ifdef _DEBUG

#define new DEBUG_NEW // Standard initialization

// If you are not using these features and wish to reduce the size // of your final executable, you should remove from the following // the specific initialization routines you do not need. CDFSearchDlg dlg; m_pMainWnd = &dlg; int nResponse = dlg.DoModal(); if (nResponse == IDOK) { }

else if (nResponse == IDCANCEL) { }

// Since the dialog has been closed, return FALSE so that we exit the // application, rather than start the application's message pump. return FALSE;

// TODO: Place code here to handle when the dialog is // dismissed with Cancel // dismissed with OK

// TODO: Place code here to handle when the dialog is

#undef THIS_FILE

static char THIS_FILE[] = __FILE__; #endif

//这是表示，如果生成调试版本，要指示当前文件的名称。__FILE__是一个

宏，在编译器编译过程中给它赋值为当前正在编译的文件名称
