MFC一些控件的基本用法

1.edit control

显示汉字

CString str_hege = "否";
SetDlgItemText(IDC_EDIT5, str_hege);

 

显示数字

int m ;
CString str_m;
str_m.Format(_T("%d"), m);
SetDlgItemText(IDC_EDIT4, str_m);

 

显示文件路径

string path;  //path1 = "E:\\daoju\\骨料图片\\2\\1.jpg";

CString pathname;

pathname = path.c_str();

SetDlgItemText(IDC_EDIT2, pathname);

 

2. list box

右键单击控件，选择添加变量，声明控件变量的类别为Control,变量类型为CListBox,变量名为m_ListBox_Content.

CString pathname;

m_ListBox_Content.AddString(pathname);

 

3.picture control

pc显示iplimage格式图片比较麻烦，需要和mat格式转换

mat转iplimage

IplImage*TheImage = NULL;
if (TheImage) cvReleaseImage(&TheImage);
TheImage = cvLoadImage("E:\\daoju\\骨料图片\\2\\216.bmp");
Mat img = cvarrToMat(TheImage, true);

iplimage转mat

Mat img;
IplImage imgTmp = img;
IplImage *Image = cvCloneImage(&imgTmp);

转来转去容易出错，可以使用下面的方法，把mat格式的imshow在pc上

 

4.简单的弹窗

CString str3="刀具合格";
MessageBox(str3);
