CString与string、char *类型转换

一文看懂—Agent多智能体协作 多智能体协作已成为AI应对复杂任务的关键范式,通过模拟人类团队分工,实现专业化、高效化和纠错能力。本文系统阐述了多智能体协作的核心概念(智能体分工、工作流编排、工具使用)、与产品规划的关联(任务拆解、错误处理、组织架构设计),以及典型应用场景(报告生成、客服工单、学习规划)。同时剖析了常见陷阱(循环卡死、信息失真、成本失控)及解决方案,并提供了实用工具模板(角色定义卡、工作流画布、成本仪表盘)。最后通过市场竞品分析和旅行规划两个实战案例,展示了多智能体协作的实际价值。该技术正推动AI从单点智能迈向系统智能, 阅读详情

字符串处理

win10,VS17中

1.新建MFC工程,选择对话框程序。


2.默认为Unicode字符。为两个按钮添加消息。



void CCStringDlg::OnBnClickedOk()//确定
{
	//string		-->CString
	//char *		-->
	//const char*           -->
	string str = "string1";
	char* s = "char*1";
	const char* ss = "const char*2";

	CString cstr;
	cstr = str.c_str();
	cstr = s;
	cstr = ss;
	GetDlgItem(IDC_STATIC)->SetWindowText(cstr);


	//CString --> string
	//        --> const char*
	CString cstr2 = _T("CString2");

	string str2 = (CStringA)cstr2;
	const char* s2 = str2.c_str();
}
void CCStringDlg::OnBnClickedBtn()//按钮2
{
	//string --> const char*
	//	 --> char*
	string str = "string";

	const char* s = str.c_str();
	char* p = new char[str.length()+1];
	//memset(p,'\0',str.length()+1);
	//strcpy(p, str.c_str());
	strcpy_s(p, str.length() + 1, str.c_str());

	//char* --> string    const char* --> string
	char* s2 = "char *";
	const char* s3 = "const char *";

	string str2 = s2;
	string str3 = s3;

	CString MFCstr;
	MFCstr = p;
	MessageBox(MFCstr, _T("显示"));

HighTec安装(官网免费)编译 嘎嘎详细~

安装软件最好有自己的一套安装规则,工程软件除了安装主体外还会有很多其他的东西,比如license或者还会有一些驱动,如果所有都随意安装会导致你需要卸载,或者更新软件时,有的需要将原来软件卸载干净,如果没有清晰的安装路径那真是灾难啊~请确保此目录中只有个人许可证。这样基本的配置就ok了,下面打开hightec软件检验下license是否识别到了,会让你选个工作区,建议自己建一个,要不你以后就找不到了,,,如下图拉到下面,按照要求填写信息,随便写就行,注意主要的MAC地址要填本机的物理地址,然后点击2即可。

激光雷达与相机外参标定(附open3d python代码)

现在的激光雷达与相机的标定程序基本都是Ubuntu框架下面的,并且都是C++代码,需要安装的依赖也比较复杂,于是自己写了一个python版本的标定程序,依赖非常简单,Windows系统也可以运行。我这里用的大疆的雷达,点比较密集,更容易用我这种方法标定,旋转的16,32线的雷达也可以用这种方法标定,只是标定点会相对难选取一些。2 手动在点云上选取N个标定点(每个点都对应图像上的点,顺序也要一致)3 通过PNP方法计算出二者的旋转投影矩阵,也就是外参矩阵。1 手动在图像上面选取N个标定点。
