按钮触发事件,启动线程:
pThread=new CWinThread(); pThread->m_bAutoDelete=false; // m_pMainDlg = ::AfxGetMainWnd(); pThread=AfxBeginThread(ThreadProc, this); if(pThread==NULL) { //MessageBox(L"启动失败,自动关闭"); //return FALSE; } b_ThreadRunning=TRUE;
void CInfoBridgeDlg::CheckRequestInfo() { int cnt=0; cnt=m_ListCtrl_Entity.GetItemCount(); CString show_content=L"有请求,请处理"; CString no_show_content=L"无请求"; if(cnt>0) { if(timer_has_entity_id_count%2==1) { m_bSendMessage.Attach(IDC_BUTTON_SendMessage, this, RED, WHITE, DKGRAY); Invalidate(); SetDlgItemText(IDC_STATIC_entity_id_notification,show_content); FlashWindow(TRUE); } else { m_bSendMessage.Attach(IDC_BUTTON_SendMessage, this, BLUE, WHITE, DKGRAY); Invalidate(); } timer_has_entity_id_count++; } else { timer_has_entity_id_count=0; m_bSendMessage.Attach(IDC_BUTTON_SendMessage, this, BLUE, WHITE, DKGRAY); Invalidate(); SetDlgItemText(IDC_STATIC_entity_id_notification,no_show_content); FlashWindow(FALSE); } Sleep(1000); } bool b_ThreadRunning=TRUE; // CInfoBridgeDlg message handlers static unsigned int ThreadProc(LPVOID pParam) { while(b_ThreadRunning) { ((CInfoBridgeDlg*)pParam)->CheckRequestInfo(); Sleep(1000); } return 0; }
