    #ifndef NO_EXPORT_MAIN

2.

   // Local iconic variables
5.  
   HObject ho_Img5131;

    ReadImage(&ho_Img5131, "C:/Users/Administrator/Desktop/DSC_0097.JPG");
11.  
    dev_open_window_fit_image(ho_Img5131, 0, 0, -1, -1, &hv_WindowHandle);
12.  
    if (HDevWindowStack::IsOpen())
13.  
    ClearWindow(HDevWindowStack::GetActive());
14.  
    if (HDevWindowStack::IsOpen())
15.  
    DispObj(ho_Img5131, HDevWindowStack::GetActive());
16.  
    system("pause");
17.  
     
18.  
    return 0;
19.  
    }

 这时候我们的代码就成功导入vs2019了，运行一下，有一个问题

 界面是黑屏的，找了好久好久，加了一行代码

 SetSystem("use_window_thread", "true");

1.  
   int main()
2.  
   {
3.  
   SetSystem("use_window_thread", "true");
4.  
   // Local iconic variables
5.  
   HObject ho_Img5131;
6.  
    
7.  
   // Local control variables
8.  
   HTuple hv_WindowHandle;
9.  
    
10.  
    ReadImage(&ho_Img5131, "C:/Users/Administrator/Desktop/DSC_0097.JPG");
11.  
    dev_open_window_fit_image(ho_Img5131, 0, 0, -1, -1, &hv_WindowHandle);
12.  
    if (HDevWindowStack::IsOpen())
13.  
    ClearWindow(HDevWindowStack::GetActive());
14.  
    if (HDevWindowStack::IsOpen())
15.  
    DispObj(ho_Img5131, HDevWindowStack::GetActive());
16.  
    system("pause");
17.  
     
18.  
    return 0;
19.  
    }

 最后运行

成功显示图片
