VS2008工程,因结构体字节对其问题导致的string赋值出现崩溃,求大佬解答 未手动字节对其的情况下,sizeof(结构体) = 77, 在手动对其的情况下赋值不出现崩溃, 求大佬求解! 解决方案 » 免费领取超大流量手机卡,每月29元包185G流量+100分钟通话, 中国电信官方发货 #pragma pack 指定结构体字节对齐试试看#pragma pack(push, 8)typedef struct _tagxxxx_t{}xxxx;#pragma pack(pop) #pragma pack 我试过不会崩溃, 结构体变量位置调整也不会出现崩溃。我只是想知道为啥string赋值会崩了 结构体以这种形式定义也不会出现崩溃int iLine; int iCorner; int total_layer; float pixel_to_mm; float min_length; float max_length; float max_angle_thresh; bool isDrawBarcode; // 是否在图片上绘制条码 bool isDrawLine; bool isShowData; bool isShowAngle; bool isDetectAngle:2; cv::Rect detected_rect; std::string strBarcode; 已经有写了赋值操作符,这是一整个结构体代码typedef struct stInputParams{ int iLine; int iCorner; int total_layer; float pixel_to_mm; float min_length; float max_length; float max_angle_thresh; bool isDrawBarcode; // 是否在图片上绘制条码 bool isDrawLine; bool isShowData; bool isShowAngle; bool isDetectAngle; cv::Rect detected_rect; std::string strBarcode; stInputParams() { iLine = 1; iCorner = 1; total_layer = 5; pixel_to_mm = 0.01f; min_length = 0.1; max_length = 1.4f; max_angle_thresh = 90.0f; isDrawBarcode = false; isDrawLine = true; isShowData = true; isDetectAngle = true; isShowAngle = true; detected_rect = cv::Rect(0, 0, 0, 0); strBarcode = std::string("ERROR"); } stInputParams operator=(const stInputParams& params) { iLine = params.iLine; iCorner = params.iCorner; total_layer = params.total_layer; pixel_to_mm = params.pixel_to_mm; min_length = params.min_length; max_length = params.max_length; max_angle_thresh = params.max_angle_thresh; isDrawBarcode = params.isDrawBarcode; isDrawLine = params.isDrawLine; isShowData = params.isShowData; isDetectAngle = params.isDetectAngle; isShowAngle = params.isShowAngle; detected_rect = params.detected_rect; strBarcode = params.strBarcode; return(*this); }}stInputParams; 请教,如何设置vs2008,使能以c++语法解析*.pc文件?多谢 如果获得BIOS信息???? 高分求教PlatformSDK与ADO编译路径包含冲突的问题 关于线程 创建对话框 大3学生为了课程设计将要跳楼,救命的快来。。。 我想问一下mysql的c语言接口问题关于mysql_real_connect() 问一个数学题 关于Semaphore的问题:ReleaseSemaphore()的另一个用法。 关于CView和CFormView的问题。请高手帮忙,多谢!!!! 如何遍历桌面上的所有窗口 MFC中父子窗口传递参数问题 C语言求助
