我在 Visual Studio 2010 C++ 控制台中完成了我的工作，但现在我正试图在 Visual Studio C++ 中将我的工作转换为 Windows 应用程序（制作它的界面）。为此，我必须添加一些头文件，我必须在 Windows 表单应用程序中手动添加这些头文件，例如

在此处输入图像描述

它向我展示了一些错误，例如

DetectRegions.h(10): error C2146: syntax error : missing ';' before identifier 'filename'
DetectRegions.h(10): error C4430: missing type specifier - int assumed. Note: C++ does not support default-int

DetectRegions.h(18): warning C4183: 'histeq': missing return type; assumed to be a member function returning 'int'

Plate.h一样DetectRegions.h

opencv我在 Form1.h 中添加了其他标题，例如

#include "opencv2/features2d/features2d.hpp"
#include <opencv/highgui.h>
#include "opencv2/opencv.hpp" .......

您在 DetectRegions.h 中使用 std::string 和 std::vector，但不包括它们的标头

#include <string>
#include <vector>

同样，如果您在那里使用 cv 标头，则需要在其中包含它们。
