如何在代码中（C++）跳过dongle实现 compile code

Question

问题：如何通过修改代码跳过dongle 实现compile code

已使用的方法: comment out 源代码中使用smart dongle 部分，出现了一下窗口。

 

软件版本: Microsoft visual studio 2019.

 

以下是包括smartdongle的代码 (App.cpp)：

#include "smartdongle.h"

/*
....
....
*/

App::App()
{
	unsigned __int64 P1, P2;
	int error;
	//char errorString[QTS_ERROR_STRING_LENGTH_MAX];


   //SmartDongle  Demo Keys
   P1 = /* 没有展示的一串数字符*/;
   P2 = /* 没有展示的一串数字符*/;  


   while (1)
   {
	   error = SmartDongleRead(P1, P2, 0, NULL, 0);
	   if (error)
	   {
			
			int userchoice = AfxMessageBox("A valid Dongle is not present\n", MB_RETRYCANCEL);
			if(userchoice == IDCANCEL)
			{
				PostQuitMessage(0);
				break;
			}
		 
		//  SmartDongleGetErrorString(errorString, error);
		//  AfxMessageBox(errorString);

	   }
	   else
	   {
		   break;
	   }
   }


}

以下是部分 smartdongle.h

/*

SD_ERROR:
