Encapsulates a modeless dialog window in DLL, but wants to block the main thread at runtime, but does not block the interface

Void DoEvent (); DWORD WINAPI doModal (LPVOID p) {INT I = 0; while (1) {ionization; Sleep (30); if (I = = 83) break; static MSG msg; if (:: PeekMessage (& msg, NULL, 0,0, PM_NOREMOVE) {AfxGetApp ()-> PumpMessage ();}} return 0;} void DoEvent (CScale3DCMessageBoxDlg & dlg) {MSG msg / / fetch the message and retrieve the message queue of the application. Remove if (:: PeekMessage (& msg, NULL, 0,0, PM_REMOVE) from the message queue after PM_REMOVE is fetched) {/ / send message: TranslateMessage (& msg);: DispatchMessage (& msg); dlg.SendMessage (msg.message, msg.wParam, msg.lParam) }} extern "C" _ declspec (dllexport) VOID _ stdcall CreateMsgBox (CWnd * parent) {CScale3DCMessageBoxDlg pDlgMsgBox; pDlgMsgBox.Create (IDD_DIALOG1, parent); pDlgMsgBox.ShowWindow (SW_SHOW); HANDLE hThread [1]; DWORD threadId; hThread [0] = CreateThread (NULL, 0, doModal, 0,0, & threadId); DWORD dwRet Do {dwRet =: MsgWaitForMultipleObjects (1, hThread, FALSE, INFINITE, QS_ALLINPUT); if (dwRet! = WAIT_OBJECT_0) {pDlgMsgBox.UpdateWindow (); DoEvent (pDlgMsgBox) }} while ((dwRet! = WAIT_OBJECT_0) & & (dwRet! = WAIT_FAILED));} after reading the above, do you have any further understanding of how to simulate the doModal dialog box?
