MFC的edit control控件显示

1.控件添加变量M_edit后：

CString str;
int x = 10;
str.Format(_T("%d"),x);
M_edit.SetWindowText(str)

2.控件ID为IDC_EDIT1:

CString str;
int x = 10;
str.Format(_T("%d"),x);
SetDlgItemText(IDC_EDIT1,str);

线程函数使用

采用afxBeginThread():

UINT __cdecl ThreadSHOW(LPVOID lParam);//声明UINT __cdecl ThreadSHOW(LPVOID lParam)//定义
{CMFCApplication1Dlg* pDlg = (CMFCApplication1Dlg*)pParam;CString str_num;for (;;){if (pDlg->show_flag){str_num.Format(_T("%d"), pDlg->int_num++);pDlg->SetDlgItemText(IDC_EDIT1, str_num);}if (pDlg->thread_stop_flag){return 0;}}
}

//show_flag、int_num、thread_stop_flag都是在mfc的类中定义的全局变量

//调用

AfxBeginThread(ThreadSHOW, (LPVOID)this);
