调用方式:
/* * add the ActiveX control view */ m_ActiveXControl_View = NULL; m_ActiveXControl_View = new CActiveXControl(this); if(-1 == m_ActiveXControl_View->Load()) { delete m_ActiveXControl_View; m_ActiveXControl_View = NULL; } ModifyStyle(0,WS_THICKFRAME,0); MoveWindow(200,100,1000,600,TRUE);
单进程:
::CreateMutex(NULL, TRUE, "XDCNET XDbList.exe"); if(GetLastError()==ERROR_ALREADY_EXISTS) { //关闭原进程 HANDLE handle = NULL; HWND hand = NULL; DWORD dProcessID = 0; dProcessID = GetPIDByName("XDbList.exe");//Get Process by ProcessName handle = OpenProcess(PROCESS_ALL_ACCESS, FALSE, dProcessID); TerminateProcess(handle, 0); } DWORD CDialogApp::GetPIDByName(CString Name) { PROCESSENTRY32 pe32; pe32.dwSize = sizeof(pe32); HANDLE hProcessSnap = ::CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0); if(hProcessSnap == INVALID_HANDLE_VALUE) { return 0; } BOOL bMore = ::Process32First(hProcessSnap, &pe32); while(bMore) { if(_stricmp(pe32.szExeFile,Name)==0) { return pe32.th32ProcessID; ::CloseHandle(hProcessSnap); } bMore = ::Process32Next(hProcessSnap, &pe32); } ::CloseHandle(hProcessSnap); return 0; }
MFC打印机制
MFC线程中有 主窗口和活跃窗口,MFC添加活跃窗口打印界面,
窗口实现堆叠重绘
所有窗口在自己的OnDraw中实现CDC重绘,叠加绘制。
