IDC_STATIC是静态文本框的IDvoidCTextDlg::OnBnClickedButton1(){SetDlgItemText(IDC_STATIC,TEXT("hello"));}voidCTextDlg::OnBnClickedButton2(){CStringstr;GetDlgItem(IDC_STATIC)->GetWindowText(str);MessageBox(str);}

首先在在visual studio2022资源视图中添加两个dialog分别打开每个dialog并绑定类，需要指定基类为CDialog在主界面中添加两个按钮，并分别给按钮绑定click事件（或者双击按钮）首先绑定模态对话框事件，进入DialogDlg.cpp，#include"CMdlDialog.h"//引入模态对话框绑定的类//模态对话...

voidCMFCApplication1Dlg::OnBnClickedaaa1(){//TODO:在此添加控件通知处理程序代码CFolderPickerDialogfd(NULL,0,this,0);if(fd.DoModal()==IDOK){CStringstrFolder;strFolder=fd.GetPathName();//MessageBox(strFolder);SetDlgItemText(IDC_EDIT1,strFolder);}}
