3、这里为不带Dlg的那个项目文件

// testDll.cpp : 定义应用程序的类行为。//#include "stdafx.h"#include "testDll.h"#include "testDllDlg.h"#include "LoadDLL.h"//*************原来的代码不动******************BOOL CtestDllApp::InitInstance(){ //这里上面不动，下面加载DLL，就是游戏读条一样的，现在只有一个 if(LoadDll("C://Users//Administrator//Desktop//ZJDLLV1.0.3.dll") == FALSE) { AfxMessageBox("ZJDLLV1.0.3.dll，加载失败!"); AfxGetMainWnd()->CloseWindow(); } else { AfxMessageBox("ZJDLLV1.0.3.dll，加载成功!"); } //下面系统的 CtestDllDlg dlg; m_pMainWnd = &dlg; INT_PTR nResponse = dlg.DoModal(); if (nResponse == IDOK) { // TODO: 在此放置处理何时用 // “确定”来关闭对话框的代码 } else if (nResponse == IDCANCEL) { // TODO: 在此放置处理何时用 // “取消”来关闭对话框的代码 } // 删除上面创建的 shell 管理器。 if (pShellManager != NULL) { delete pShellManager; } // 由于对话框已关闭，所以将返回 FALSE 以便退出应用程序， // 而不是启动应用程序的消息泵。 return FALSE;}

4、这里带Dlg的那个项目文件

#include "LoadDLL.h"//-------中间的不动---------//这里是按钮单机自动生成的槽函数void CtestDllDlg::OnBnClickedOk(){ WORD reslut = MFCdll_OneWORD_SixWORD(2017,9,7,15,23,0); if(reslut == 1) { AfxMessageBox("软件可正常使用！"); } else if(reslut == 0) { AfxMessageBox("软件已过期！"); } AfxMessageBox(MFCdll_OneCHAR_OneVOID());}
