    return FALSE;
  }

  MFCdll_OneWORD_SixWORD = (pMFCdll_OneWORD_SixWORD)GetProcAddress(g_Hinstance, "ZJY_SoftOverTime");
  MFCdll_OneCHAR_OneVOID = (pMFCdll_OneCHAR_OneVOID)GetProcAddress(g_Hinstance, "ZJY_GetSystemDisk");
  if(NULL == MFCdll_OneWORD_SixWORD || NULL == MFCdll_OneCHAR_OneVOID)
  {
//    AfxMessageBox("加载动态库MFCCallBackDllTest函数失败");
    FreeLibrary(g_Hinstance);
    g_Hinstance = NULL;
    return FALSE;
  }
  return TRUE;
}

//卸载DLL
void UninstallDll()
{

    MFCdll_OneWORD_SixWORD = NULL;
    MFCdll_OneCHAR_OneVOID = NULL;
    FreeLibrary(g_Hinstance);

}

2、LoadDll.h

#ifndef __MFCCLOADDLL_H
#define __MFCCLOADDLL_H

#include <windows.h>

BOOL LoadDll(char *name);  //加载DLL
void UninstallDll();    //卸载DLL

/************************************************************************/

/************************************************************************/
/*易语言使用外部定义
/***********************************************************************/
extern pMFCdll_OneVOID_OneVOID    MFCdll_OneVOID_OneVOID;
extern pMFCdll_OneWORD_OneVOID    MFCdll_OneWORD_OneVOID;

#endif    //MFCCLOADDLL_H

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());
}
